There are some differences that should be noted in the issue of LED TV vs. LCD TV. For starters, a traditional LCD television was created to use florescent lighting or another form of flat lighting while an LED TV will make use of a diode that emits light through an LCD panel. Furthermore, there are a number of different lighting styles within both LED and LCD TVs. For instance, some models contain an LED light panel located behind the LCD panel. In other models, LED lights are found around the outer rim of the screen. While in other models LED lights are tricolored and can be controlled in a way that will allow the picture to have stronger contrasts with blacks and bright colors. This feature is known as local dimming which is ultimately what makes the LED TV so different from traditional LCD television.
Picture Differences between LED TV Vs LCD TV
When a traditional LCD television is in operation, the backlight is always on. LCD televisions create dark areas in contrast by twisting crystals to a closed position to block light. This method provides fewer details in dark areas of the screen by offering a small contrast ratio. The local dimming of LED technology will correct the lower quality dark areas in LCD television. Since the LED diodes that control the lights in this technology are capable of being dimmed rather than blocked, higher details in darker areas of the picture are created. Therefore, LED TV Vs. LCD TV will find a greater advantage in the local dimming possibility of LED technology, simply for the higher contrast providing a detailed picture, and displaying more realistic color.
Life of LED and LCD TV
Another consideration in the LED TV Vs. LCD TV issue is the lifetime of the two television technologies. Many manufacturers will claim that their model will produce roughly 100,000 hours of life. However, since LED is still fairly new there is little data that states the length of the lifecycle of this television. Also model, manufacturer, and type of LED technology can play an important part in determining lifespan. It is true to say that since LED TV technology displays a better picture, there are a larger number of LCD TVs with this technology being produced than traditional LCD television. As this continues it is safe to say that the lifespan of an LED TV will become increasingly longer as itís popularity continues grows.
Differences in Power of LED and LCD
In LED TV Vs. LCD TV is important to mention that the LED diodes used in local dimming will consume more power than traditional LCD televisions of the same size. In fact, the local dimming LED technology uses almost as much power as a plasma television. However, although the traditional LCD TV uses less power than the local dimming LED TV technology, it is also true to say that the white edge lit LED technology (LED lights located around the edge of the screen) uses less power than both LCD TV, and local dimming LED TV.
