Watching television is a favourite pass time to people all over the globe. In fact, using the TV to play games and watch movies has become such an important part of the lives of society, that manufactures continue to search for ways to enhance the television experience. In most cases, this includes a clearer picture, a bigger screen, or better sound. All of these aspects are wrapped up into the latest TVs inventions known as the LED high definition television.

This drive toward giving viewers a more enjoyable TV watching experience has lead to the latest in trends, the LED television. In basic terms, a LED TV can exist as a LCD TV that uses Light Emitting Diode (LEDs) to clarify the picture screen display or as an LED TV which uses complete LEDs. LEDs more effectively direct light in one direction than fluorescent or incandescent bulbs. In a LCD TV, the LEDS are either placed along the back of the screen or around the edge of the screen. When the LEDs are used along the perimeter of the display screen, the term edge lit is labelled to the product.

The use of LED technology in a television allows for slightly different viewing. The size of a television screen using LEDs is limited to 40 inches or greater thus the screen is much larger than those of other TV types. However, the screen is slimmer and sleeker in depth. Typically, a LED television with LEDs along the perimeter of the screen cost less than a TV with back-lit LEDs. Using LEDs around the edges of a TV allows for an even narrower screen option. Yet, a back-lit LED television screen allows for local dimming in which darker blacks are created when LEDs are shut off.

As great as owning a LED HDTV sounds, it is not a purchase to make without a serious consideration of cost. An LED HDTV may cost the buyer $4000. However, serious TV gamers and film watchers will likely find that the capabilities of the LED HDTV to portray fast motion is well worth the money spent. Many claim that they never imagined the difference in picture until viewing the screen. Those concerned about the environment and energy consumption also believe that the 40% cut by the LED TV sets off the upfront cost.

Once the decision to upgrade has been made, there are several factors to consider before shopping for a new TV. A careful comparison should be made between LED TVs, LCD TVs, and Plasma TVs. The newest of the three, LED TVs, offer larger screen options. Their viewing angle is still short of the plasma but the reflective screen and burn out issue are not a problem.

The LED screen has allowed for the capabilities of larger, wider screens. These LED screens are composed of many LEDs combined to form small dots or pixels. A color LED screen has three colors of LED pixels. The pixels are red, green, and blue. When put together, these pixels form white. One single meter of a LED screen can house over 9000 pixels. The number of pixels per meter is determine by the pixel pitch, which is the distance between each pixel. The smaller the pixel pitch in an LED screen, the higher definition the viewer receives and the higher cost the buyer pays.

In addition to the discovery of LED screens in the television world, NCE has broken through with the LED monitor. The LED monitor, like the LED TV screen, promises to offer the best color and clarity. Again these features are not priceless. A LED monitor offers the same features of the LCD flat panel monitor but with more accurate coloring. The high end of the LED monitor price spectrum ranges up to and over $6000. However, one positive aspect about the LED monitor is the absence of Mercury as found in fluorescent backlights.

While there is no rush to run out and upgrade all electronic screens to LED screens, it does appear that this is where the future of viewing is headed. In given time the cost of the screens along with the size capabilities will decrease making LED TVs a common sight in homes everywhere.
