Which HDTV Should I Go For LDC, Plasma, LED Or 3D?

Which HDTV Should I Go For LDC, Plasma, LED Or 3D

With so many HDTV options nowadays it is easy to get confused and end up making the wrong choice or one that doesn't stand up to your expectations.

First of all we need to understand the basics of each HDTV type. Today we have 4 types of HDTVs and they are: LCD, Plasma, LED and 3D, there is a fifth type which is OLED but the technology is in its infancy and you can only find OLED TV sets as big as 19 inches.

LCD High Def TV Sets:

Liquid Crystal Display Televisions (LCD TV) were first introduced by Sharp in 1998, but the liquid crystal display technology has been around since the 80's when it was mainly used in portable computers.

LCD TVs offer bright crystal clear images, super colour-filled pictures but not so good contrast ratio when compared to Plasma. Over the years LCD TV manufacturers have made great improvements on LCD TV's contract ratio but Plasma still lead the way in this category.

Colour accuracy of LCD TV sets are influenced by room light. LCD TVs perform better in brighter rooms due to anti glare technology and brightness. Another factor to consider is viewing angles, on average LCD HDTVs has around 120 degree viewing angles but they still have a long way to go before catching plasma.

On average these TV sets have an autonomy of 100,000 working hours which is about 50 years of use if they are turned on for 5 hours a day.

Plasma High Def TV Sets:

Plasma technology consists of hundreds of thousands of individual pixel cells. Each pixel cell is an individual microscopic light bulb that has a mixture of noble gases and a tiny amount of mercury. When these cells receive electric pulses the gases and mercury form plasma that produces light, illuminating the exact balance of red, green and blue phosphors of each cell which in turn will display the proper colour sequence from the light.

Plasma TVs have the best contrast ratio between all HDTVs, on average the latest Plasma HDVT sets have a contrast ratio of 5,000,000:1. Contrast ratio is a measure of the blackest black compared to the withest white. Plasma TVs can achieve outstanding black levels thanks to internal algorithms that block the power to particular pixels to render a darker pixel. The down side here is that this limits Plasma televisions gray scaling.

Plasma displays can reproduce as much as 16.77 million colours because as afore mentioned each pixel has red, green and blue elements needed to produce every colour in the spectrum. In short, Plasma TVs have the best colour accuracy of all HDTVs.

Another point in favour of Plasma TVs is viewing angles. Plasma manufacturers have nearly achieved perfection with viewing angles nearing the 180 degree mark. Also worth baring in mind that Plasma TVs are more suitable for darker rooms.

LED TVs

LED TVs are the new form of LCD TVs. These TV sets can produce images with greater dynamic contrast with a wider colour gamut and lower power consumption of at least 20-30% when compared to traditional LCD TVs.

LED backlighting allows these TV sets to be extremely thin, most models are approximately one inch think.

Many industry expert don't agree to label LED TVs as unique HDTV category because as afore mentioned LED TVs are simply LDC TVs with LED lights for back lighting instead of fluorescent CFL lighting.

LED TVs presented a solution to the low contrast levels found on traditional LCD TVs. By dimming the back light in areas where the screen should be dark it increases the black levels, consequently increase the contract ratio.

Colour accuracy is very similar to LCD TVs but LED TV has an advantage in displaying more realistic colours. Just like on LCD, LED TVs have very poor viewing angles.

3D Ready TV Sets

The latest on high definition TV, all major manufacturers are producing it with highlights to Sony and Samsung, which in my opinion are manufacturing the best 3D TV sets at the moment.

3D video technology has been around for ages but only now the technology has finally reached our homes. 3D TV sets are Full HD and have resolution of 1920X1080p, a refresh rate of 600Hz and usually support HDMI 1.4 or higher.

Now that you know everything there is to know about the HDTVs you are ready to out buy one that will suit your viewing needs.

What is the Difference Between Plasma TV, LCD TV and LED TV? Simple Must You Know

Difference Between Plasma TV, LCD TV and LED TV

Over the past decade home entertainment technology has really taken some huge leaps forward. Today, the task of buying a new TV is not just a matter of picking your favorite brand or buying the largest size you can afford. There seem to be more options than ever, and this has certainly led to a lot of confusion among consumers. With that in mind, what exactly are the main differences between the different types of TV, and which is the best all

Plasma TVs are one of the older types of flat screen. They are relatively cheap to produce meaning that prices are generally low for the screen size, which led to plasma becoming a popular choice with consumers who wanted to get the largest screen for their money. These TVs use a gas, which then turns into plasma when an electronic current is passed through it; the plasma then emits the light to create the pictures. This results in a high quality, realistic picture that doesn't suffer from motion blur. It also offers a particularly wide viewing angle.

However, plasma screens do tend to only have a lifespan of about 10-15 years and do use a relatively high amount of energy, which is now frowned upon as many consumers are trying to become more environmentally friendly. Plasma screens are also quite thick, and are very heavy for their size, so they can be awkward to move. The screen is also fairly susceptible to glare, especially in bright rooms.

LCD TVs can trace their roots back to computer monitors and were first introduced at around the same time as plasma TVs. These TVs use the same basic technology as your pocket calculator screen and are backlit with fluorescent light. They have a much longer lifespan than plasma screens, something in the region of 30+ years, and also use much less power. Traditionally LCD prices were higher than plasma, but as new manufacturing techniques have evolved the prices are now rapidly falling.

While LCD TVs are available in a wide range of sizes, they do offer the worst performance of all the flat screens though, not only do they have the lowest contrast level but they also have a slow refresh rate meaning that motion blur often occurs. The viewing angle is also much narrower than that of plasma TVs, which means that it can be difficult to find a location that offers a good view for everyone, especially in smaller rooms.

LED TVs are actually the next generation of LCD screens, as they are based on a similar technology but use LED backlighting instead of the fluorescent backlighting found in traditional LCD screens. The new backlighting technology means that they are able to deliver a much more dynamic picture quality, they also use significantly less power than even the most efficient LCD TVs. LED screens can be made to be extremely thin, so they offer consumers the ability to place the TV practically anywhere - indeed it is now commonplace to see TVs fastened to the wall in order to save floor space.You can watch this video for more know What Is difference between PlasmaTV, LCD TV And LED TV. Check it Out :

As this is still a relatively new development, LED screens do tend to be more expensive than their LCD counterparts. However as LED TVs become more widespread the cost of production is expected to drop significantly, which will be reflected through dramatically lower prices in-store. Having said that, LED technology is considered to be the most reliable of all the flat screen formats so many people don't mind paying a little bit more.

The world of home entertainment can certainly be a confusing place, especially as new advances in technology seem to come along on an almost monthly basis. Hopefully this article has shed some light on the current generation of flat screen TVs, so at least you can stand a fighting chance the next time you venture into the home entertainment section of the electronics store.

The Smart TV Revolution

The Smart TV Revolution

What is a Smart TV all

Smart TV's offer the capabilities of a computer, from a television set. It offers a multitude of services that ordinary TVs can't. These TVs, also called connected TV or hybrid TV, is the name given to any technology that connects the features of the web to a television set. It offers access to apps, games, web browsing and Internet Protocol Television, or iPTV.

iPTV allows users to view streaming video from the internet; either video clips or continuous channels. Smart TV offers the ability to access the same content that is on the web from the comfort of the living room. The concept of connecting the internet to a television set isn't entirely new, but technological advances are bringing the idea alive and making it easier than ever. The technology doesn't require the purchase of a new television set when they may have just recently purchased one; it is possible to connect to a set top box, game console, blu-ray player, etc.

Why do I need a Smart TV?

The devices allow users to download music or videos from the web and access them directly from their television, eliminating the need to create CDs or DVDs. There are numerous video streaming websites available that offer video clips, television show episodes, full-length movies, and live continuous feed. Netflix users can easily access movies and TV episodes on their smart TV. Now, instead of crowding around a small computer screen to watch an online movie, everyone can gather together on the couch instead. Sites like Hula, Roku, Boxee, and Apple TV also offer an abundance of available videos that can be accessed via a smart TV.

Internet gaming enthusiast will love the accessibility of their favorite game on a wide screen HDTV. Gaming will be transformed into a more comfortable and visually pleasing experience.

How does it work?

These TVs use an Ethernet cable, some can even go wireless. The process of setting up a smart TV is very similar to setting up a laptop. They run on an operating system, similar to regular computer, only made specifically for use with a television. This allows for the use of the apps and features, either pre-programmed or available for purchase and download. The TV can be controlled with an android or apple smart phone, or even wirelessly.

The future of the Smart TV

Television sets are being transformed from an object in the home used for watching video to a truly interactive experience that the whole family can enjoy. TV manufacturers are working with internet companies to provide better services for their customers. These manufacturers will continue to improve the operating systems they offer so that customers will continue to get the best from their TV. As with any new technology, companies will compete to offer the newest and greatest versions, which mean there will always be something new to look out for.

Plasma, LED, or LCD for Outdoor - Advantages and Disadvantages

Plasma, LED, or LCD for Outdoor - Advantages and Disadvantages

Outdoor digital signage is growing industry with over ten percent of all outdoor advertisements now a digital screen of some shape or another. The screens used for digital advertising are, in essence, the same sort of devices that we use in our homes, although commonly they are of a more durable commercial variety.

There essentially three flavours of modern flat screen TV devices: the plasma, LED and the LCD. LCD (Liquid Crystal Display) uses a crystal fluid between two plates that when electrified produces and image. This is then illuminated by a backlight to create the TV image. LED TVs work in a similar way using liquid crystal except that the backlight is generated by the tiny light emitting diodes.

Plasma on the other hand uses completely different technology, rather than using liquid crystal it has a sheet of plasma (a state of matter beyond to solid, liquid, or gas) which, when electrified, is activated to create the image.

There are advantages and disadvantages to all three systems. Plasmas are bright and require no backlight, LCDs are cheaper to produce and last a long time; LEDs have similar properties but are slightly more expensive but use less power while plasmas tend to be brighter and have a better picture quality.

But which is best for outdoor digital signage all

Well there are advantages and disadvantages to all systems. Strictly speaking plasma screens are good for outdoor locations because of the wider contrast range; however, they also generate a lot of heat that can cause problems but the viewing range is better.

LCD screens are more commonly used now as they are more reliable and with the advent of high brightness screens they are now more common than plasmas, especially with LED backlit screens that have better contrast and brightness.

Whatever option people decide to use, protection for outdoor digital signage is readily available in the from of an outdoor LCD enclosure which will contain either type of television and will protect it from the weather, vandalism and temperature.

Plasma HDTV 1080p - How Long Will Your TV Set Last?

Plasma HDTV 1080p - How Long Will Your TV Set Last

If you are planning to replace your old tube TV with a fancy plasma HDTV but feel worried about the stories of "plasma's burn-in and lifespan issues" here is what you need to know. The latest plasma technology used by reputable manufacturers has the lifespan projections equal to those of LCD screens, which is about 60,000 hours. Depending on your daily usage this may translate to anywhere between 12 and 55 years.

Early versions of plasma displays had an annoying flow - the dreaded "burn-in" or "ghost image" effect. This problem was caused by an ongoing presence of static images such as network logos and browser frames, which over time resulted in permanent damage to the corresponding pixels on the screen. The "burn in" effect has to do with the properties of phosphor used in plasma technology and the way it reacts to light and electrical impulses.

Fortunately, quality manufactures have been working hard to eliminate this effect. In fact, the best brands currently claim to have the burn-in resistance equal to that of a standard CRT screen. This has been made possible by advances in plasma technology such as the use of green phosphor (more resistant to burn-in) and motion adaptive technology. The latter prevents the burn-in effect through microscopic image movements (invisible to the human eye) that prevent static images from etching into the screen.

Plasma HDTV 1080p represents the latest advance in the TV technology. So if you are planning to invest in one here are some important tips for maximizing its lifespan:

1. Plasma monitors are generally more prone to burn-in during the first 200 hours of use. During this time (and even after) it is recommended that you avoid displaying static images for more than an hour. Avoid pausing your DVDs for more than 20 minutes at a time and remember to turn the unit off when not in use.

2. Read your TV's User's Manual and become familiar with its anti-burn-in features. Such features may include running pure gray or white screen settings ("blank screen") to recalibrate the pixels and erase any potential burn-in. This is particularly recommended after the first 100 hours of use and than later, from time to time, based on your usage type. Make sure to follow the anti-burn-in instructions for video games and other static content.

3. Watch everything in full-screen mode to avoid prolonged presence of static black areas around the active frame.

4. Instead of using the manufacturer's default contrast setting, which is usually set to 100%, reduce it to 50% - especially during the first 200 hours of use. The only times when you might feel the need to up the contrast to high is in a brightly lit room. To prevent this, turn the unnecessary lights off and use other practical ways to darken the room while you are watching your plasma TV. Reduce the brightness setting on your TV accordingly (remember "lower is better" for your screen's longevity).

5. Equipment tests have shown that some brands are more resistant to burn-in than others. The top performers include NEC, Sony, Pioneer, and Panasonic. The technology used by Hitachi and Fujitsu (AliS panel type) seems to be more affected with burn-in problems. Also, secondary (less known) brands could be affected with the same problem due to the less advanced technology.

6. Make sure there is sufficient space around your screen to prevent the unit from overheating. Keep it in a well ventilated area.

Plasma and LCD TVs - Buying A New Plasma Or LCD TV

Plasma and LCD TVs

It is always exciting when you need to buy a new television. Be careful in buying your TV because there are so many that come with a large promise, and just do not deliver. This outline will help you figure out what to look for in your new television.

Pardon the pun but, size matters when it comes to purchasing a new TV. Too small a TV you'll feel like you're watching a 19" sitting on the 50 yard line from the nose bleeds. Too large a TV you'll feel like you're watching TV in a soap box. In picking the right size TV for the place you wish to put it, follow these two simple steps. First take a measurement of the distance between where you will be watching the TV and where the TV will be positioned and divide that number by 2 - 3.5, this will give you an approximate size television to get. Second, take a diagonal measurement of the space where the TV will sit using the number you got from your calculation. This is to make sure you have room to place your new television there or you can always make room.

OK Wait, Hold Up. Before setting off on your Television shopping spree you want to do just a little more research on what type of attachments you'll need. Like, do you have a surround system that uses a coaxial audio output connection (analog) instead of an optical audio output connection (digital)all How many HD devices will you connect to your new TV? Such as DVD/Blu-Ray players, gaming consoles, and HD converter boxes. This will determine how many HD-MI ports you will need. How about, do you want to have slide shows of your pics displaying on your screen? Then a couple of USB ports may be in order to plug in digi cams and such. Asking yourself these types of questions before hand will save you a lot time on choosing the right TV. By reading customer reviews, you'll find out that this is a common mistake among consumers.

Another question you'd want to ask yourself is, what type of monitor will you need? Plasma or LCD. What will you be using the TV for? Casual watching, gaming, or sports. What type of room will the TV sit in? A dim-lite room or a well-lite room. Plasma TVs have bright vivid colors and a great picture, prefect for watching sports. Plasma screens produce deeper blacks than LCD screens and are ideal for dim-lite rooms. LCD TVs also has great picture quality, Video games look really good on them. LCD TVs are more energy efficient than plasma TVs. A con for plasma screens is burn-in, 20 minutes of a static or paused frame is all it takes. A con for LCD screens is individual pixel burn out occurs over the life of the LCD that can not be fixed.

When choosing screen resolution there's only two real choices. 720p and 1080p. 1080p is the highest resolution available for now. With that being said more and more devices and media are being geared for 1080p resolution. If you're looking to buy a larger screen TV, then 1080p is the right choice because there is a definite distinction between 720p and 1080p resolutions on bigger TVs. On smaller size TVs under 40", there's not much of a visible difference in 720p or 1080p resolutions. If you're not a big TV watcher, then you can save yourself some money and get a 720p resolution television. But of course the choice is yours.

TV warranties can be a tricky topic depending on who you are. All televisions come with a 1 yr. factory warranty which usually cover parts and labor. The tricky part is when buying an extended warranty for however many years, the first year overlaps with the factory warranty because the extended warranty starts the date the TV was purchased.

Navigating through the world of television buying can be very confusing at times. By know what you are looking for ahead of time, and you can reduce a lot of stress.

Plasma Television

Plasma Television

For years, television has evolved and changed to different sizes, features and qualities. The process of technology is unending. Technology has been integrated to many things and the most visual example of that technology integration is on televisions.

Television or what they call "boob tube" evolved in the early 1930's. There has been a lot of development as the years passed. Currently the most talked about when it comes to televisions are the so called "Plasma TV".

Now, what exactly is a Plasma TVall Maybe some of you would just say that it is a wide slim TV that you can hang around in your room where you want it or when you want it. Now, the bottom line is this, Plasma TV is not just your ordinary TV. The display that you will actually see is made up of thousand cells. These cells are glass compartments infused with a certain gas called "neon-xenon gas". This gas is now plasma suspended.

So what now is plasma? Plasma is a matter that contains number of particles that are electrically charged. When the neon -xenon gases are then electrically charged, it will give phosphors of different colors, such as red, blue and green. These colored elements are the pixels that are contained in the Plasma TV.

Now what are the Plasma TV advantages?

It's very easy to watch. A Plasma TV works well under any light conditions. Even the brightest of the lights can't wash out the pictures. Your Plasma TV screen will not be affected by the glares of backlight unlike the ordinary TVs that you have to set it in such a place where you can see it easily and clearly. Plus it is such a cool TV, very sleek and stylish.

It is wide; the picture is very colorful and smooth. Maybe you actually notice in the ordinary televisions that sometimes there are annoying lines running through the display. In Plasma TV's you will not encounter such things because they are made up of pixels, making a more colorful and smooth images. Truly a Plasma TV gives a superb resolution, an exceptional color that sets it apart from other televisions.

Plasma TV is multi functional. The plasma display could either be a home television monitor, regular TV, an HDTV capable and even a home video. Also you can use it as your computer monitor. Video formats can be accepted by Plasma TV. Different inputs are included in Plasma displays such as video, component video and one to two RGB inputs right from your computer. The average life span of a Plasma TV is for about three and half years even if you watch and use it 24/7.

A different technology was used in the Plasma TVs. Most TVs suffer distortions brought about by some magnetic fields. Plasma TVs are not affected by this even if you put it near the speakers.

Plasma TV design is very unique, it is slim and has a very light weight. Some of the Plasma TVs are just 6 inches thick, surprisingly incredible. Also it is very light, some of them only weigh 50 pounds. This makes it easier to move it around your house wherever you want it. It is very space saving. The unique design really catches attention, because it is very elegant, you would really like to buy your own.

This is the Plasma TV and its characteristics. Who would not like to buy his own? Elegant, space saving, and multi functional, just to name a few. Truly, Plasma TV really delivers. Enjoy real time entertainment with this unique TV. Watching TV will never be the same again. Plasma TV, a wonderful work of technology.       
 

Plasma screen televisions are a new type of audio visual entertainment that utilizes small, inert-gas filled cells and electricity to create plasma. The plasma then excels and activates phosphors to emit light in a pattern dictated by the positioning and the vivacity of the cells. Though plasma research and visual companionship has been used for nearly 60 years in study, it has only recently become available to the consumer public as a means of television.

Plasma screens are very bright and have a wide range of usable colors because of plasma's flexibility. Though the use of power fluctuates in accordance to the necessary level of what is being displayed (i.e. picture quality).

The lifetime of a plasma screen is extraordinary. Plasma screens can operate at factory-ready levels for years of use. They can operate like new for up to 30 years of the Television being on 10 hours a day, provided that the television is cared for properly.

However, plasma screen televisions also have caveats and drawbacks that cause them to be criticized. For instance, plasma screens tend to reflect a lot of ambient or glaring light than some other new televisions. However, some companies are rectifying this by placing an anti-glare filter on the television screen. Another problem with plasma screen televisions is the management of size. It is difficult to make plasma screens small because it takes a certain area for the plasma to be created. Making the containment area behind the screen too small can result in the plasma not being formed correctly. This results in mostly large, flat plasma screens to be the only ones commonly sold.

Also, the plasma screen television is often criticized by its amount of energy consumption. Though, overall, it is a more visually pleasing television that some of its competitors such as the LCD television (Liquid Crystal display), it also consumes more energy than the LCD. For this reason, Plasma screens have been proven to contribute to global warming causing them to gain heavy criticism for environmental rights activists. Not only do they consume a large amount of electricity due to their common size, they also produce nitrogen trifloride, a heavy greenhouse gas that can damage the ozone Though this is still a problem, research is being done to come up with solutions for the problem as Plasma has proven to be one of the most visually pleasing new televisions.

Plasma televisions are rather expensive because of their difficult makeup as well as the high cost of operating and maintaining them. For this reason, extensive warranties are often sold to protect the maintenance costs of the televisions. Plasma screen televisions can cost anywhere from five hundred dollars up to more than five thousand dollars, depending on the overall features, make, model, and visual quality. Also, the store that is selling the particular television also heavily contributes to the cost of the televisions.

Plasma screens are very visually pleasing as well as long-lasting and capable of extraordinary audio-visual display. Though they do have their problems, they are still in the top ranks of televisions being sold today.

Plasma Vs LCD Vs LED TVs - What Are the Differences

Plasma Vs LCD Vs LED TVs

In the last 10 years, TV technology has advanced to a great extent and has brought in state of art technologies in providing the finest flat-screen TVs. The most important aspect of the technology used has mainly focused around the size, resolution and compatibility and with this, in the last 5 to 10 years there has been a gradual change in the choice and viewing expectations of people.

The manufacturers have now started to put in unique features in their flat-screen TV models making the product having a distinctive advantage of full film effect viewing along with outstanding sound technology. There are various types of flat-screen TVs in the market today, and in order that you could decide between Plasma, LCD, and a LED TV, you ought to know a bit about the differences.

Overview of Plasma TV: The display in a Plasma TV is made up of millions of tiny plasma cells, and to put it simply, these cells emit light to create a complete image on the screen when a precise voltage is applied to them.

Plasma TVs available now offer larger screen size than LCDs. The screen sizes of Plasma TVs that are commonly available in the market include, 30 inch, 42 inch, 50 inch and 63 inch models, while the LCD TVs are limited to smaller screen sizes, which range from 10 inch to 40 inch models. Presently larger screen sizes of more than 60 inches are being made available in the market. One favourable point is that, the LCD technology is more flexible, which allows wide variety of screen sizes to be developed.

Advantages on Plasma TVs: extent, making the images life-like and realistic, responding sharply to fast moving images.

Disadvantages of Plasma TVs: Plasma TVS do not perform as well at higher altitudes.     Plasma TVs are more susceptible to burn-in of static images.     Plasma TVS are thicker than LCD TVs and hence much heavier.     Plasma TVs produce glare in brightly lit rooms though some advancement in technology has been made to correct this.

Overview of LCD TVs: LCD TVs have Liquid Crystal Displays, a technology which is seen being used in computer monitors, cell phones, and at times are found in camera screens. LCD screen was first created for computer monitors, and now with the application of the technology in LCD TVs, they seem to be a bit better when you are playing games on your TV. However, the choice entirely depends on the user, since some like the vivid colors in Plasma TV, which comes from its deep black levels.

LCD panels work with liquid crystal solution being sandwiched between two polarized glasses. When an electrical voltage is applied to the liquid crystal, the crystals rotate, and this changes the polarization of the light passing through them. A LCD panel does not generate light by itself. It just filters or subtracts its back light source to create an image on the screen.

Advantages of LCD TVs: LCD TVs have better longevity than the Plasma. The average life-span has been predicted as more than 30 years.     The display of LCD TVs uses lower power compared to Plasma TVs, but has more consumption than LED. -    The screen sizes of LCD TVs are available in various sizes starting from computer monitor screens to over 60 inches.

Disadvantages of LCD TVs: The TV has a very poor contrast level and responds slower to fast moving images, creating a blur.     The prices of LCD TVs are higher than the Plasma, and because of the demand and increased production the prices are gradually falling.

Overview of LED TVs: The term 'LED' stands for Light Emitting Diode. It is an electronic component which emits light when a certain voltage potential is applied to its terminals. Though the TV using this technology is call LED TV, but the LED light source is used as the TV's backlight, while the TV screen is actually LCD. Though some current TV models use CCFL (Cold Cathode Fluorescent Lamps), LED form of backlighting remains a far more efficient TV backlight system.

The Advantages of LED TVs are as follows: With LEDs as the backlighting source, the TVs have a far better dynamic contrast level than LCD TVs, since it uses a direct backlighting technology.     LED TVS are ultra thin as much as about an inch in thickness.     The power consumption of LED TVs are less than the LCD TVs currently available.     Out of the flat screen TVs available in the market today, LED TVs are considered to be most reliable.

The disadvantage is that LED TVS are higher priced than LCD TVs, but prices are expected to come down with increased production.

The above is an attempt to provide a basic conception about the differences between the three technologies available presently in flat-screen TVs which would help a buyer to decide which TV to buy.

So...since there's about a thousand TVs to choose from we're just gonna go over the vital differences between the different technologies.

LCD vs Plasma vs LED

Let's start this off by going over what is the same. Everyone is going to boast about contrast, color reproduction, smoothness, and clarity, but each technology is going to be pretty similar when you're looking at the best of each.

LCD

Pros

LCD gives you a very 3D like experience. The sets with 120Hz or more take away any artifacts (blur from fast moving objects

Cons

LCD TVs with lower than 120Hz really gives you an artifact problem. They'll be cheaper, but may not merit the savings a couple months down the road

Plasma

Pros

Nobody can touch the vividness that Plasma can create.

Big screen for little priceall.. plasma is the only way to go.

Cons

You don't get the same 3D realism that you get with LCD or LED.

Plasmas have a shorter lifespan, though with newer technology they come close

LED

Pros

Incredible 3D realism!

Incredibly thin!

Cons

It's the newest technology so it's a bit pricy

Afterthought

As you can see these TVs (newer models) are fairly similar. The smaller differences may be enough to persuade you one way or the other. Just remember, like in anything else, you get what you pay for. Find that balance between price and quality.

Important Features

Connectivity

Depending on your setup you may need more than one HDMI in. If you plan on ever hooking up a computer to your TV you're going to want to have a VGA in. Some computers and most new notebooks will have HDMI outs, but if not, look for that VGA in.

Full HD 1080p

You can save a decent amount of money if you buy a 720p model HDTV. Your eyes can only resolve so many pixels per inch. So you may not physically be able to notice a difference between 1080p and 720p. If you're TV is big enough you will see a difference. If that difference important, spend the extra money!!! If you don't see the difference save some money.

Speakers

If you don't have a speaker system set up, or you're looking to streamline your entertainment center, good speakers in your TV are a must. That in mind, if you're an audiophile, there most likely will never be a TV with speakers that will satisfy your ears.            or cell phone displays, computer monitors, and to view still images. LCD TVs have a flat screen so there will be no picture distortion and don't have screen "burn in" like curved tube TVs. In general, LCD viewing angle is 175 degrees. The picture can be viewed 87 degrees from each side. LCD TVs are very economical to use and screens less than 35 are fairly inexpensive. LCD TVs are backlit and blocks outside light. So, they are suitable for natural lighting situations. Most LCD TVs have a half lifespan (50% of original brightness) of over 30,000 hours (16 years of viewing at 6 hours per day). LCD sizes generally range from 13 to 65 but some manufacturer will offer up to 100 sizes.

Plasma TV:

A Plasma Display Panel (PDP) is a flat panel display used in large TV displays. They have better and accurate color generation than LCDs, and with far display, wider viewing angles, and do not experience degradation at high angles compared to LCD. Plasma displays are ideal for viewing motion video in large displays.

Plasma screen sizes generally ranges from 32 to 84 but some offer screen sizes up to 100.e technology.

HDTV:

HDTV or High-Definition Television is a digital television broadcasting system offering a higher resolution compared to regular television systems. HDTV is digitally broadcast unlike earlier analog broadcasting, because digital television (DTV) signals require reduced bandwidth because of digital video compression.

HDTV will not have standard TV problems, like low quality sharpness, troubles with brightness or contrast, spots, other visual, or audio imperfections, problems like double images (ghosting), and weak signals. HD television provides clearer pictures with excellent sound quality, a wider viewing screen and up-to-date scanning. HDTV will provide more and superior channels provided by regular satellite or cable television with theater system experience.

LED TV:

LED (Light Emitting Diode) TV is an LCD TV that uses LEDs for back lighting, instead of using the fluorescent lights (as it creates more black spots). They are ideally used for low-energy indicators, as substitutes for traditional light sources in general lighting and automotive lighting.

OLED TVs:

OLED (Organic Light Emitting Diode) TVs depend on light emitting polymer technology. Its features including,nd it has high-speed refresh rates.

Before purchasing a television, know the difference between each technology and purchase the one, which has your desired features and suits your budget.         Description: Know the Difference Between LCD, Plasma, HDTV, LED, and OLED Rating: 4.0 Reviewer: Mahfudz ItemReviewed: Know the Difference Between LCD, Plasma, HDTV, LED, and OLED
