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.

Out of the desire to find better, more exciting ways to watch television or take part in TV gaming has evolved the LED television. An LED television differs from that of the plasma or LCD TVs in that it uses LEDs to direct light and color resulting in more clarity. LEDs have a great capability of directing light into one direction than other lighting methods. These LEDs are either found along the edges of the screen or across the back. These two terms edge-lit and back-lit describe the different LED positions.

The methods of LED technology that manufacturers use for creating LED televisions create two different perspectives for viewers. When the LEDs are placed along the side of the televisions, the screen depth size capabilities are reduced greatly. The screen can be thinner due to the lack of LEDs in the back. An edge lit TV also costs less than a back lit LED TV. However, when the LEDs are used across the back of the televisions, deeper and darker blacks are formed. The LEDs can actually be shut off so no light comes through. In the television world this is referred to as local dimming.

The cost of the clarity and color improvements with a LED HDTV comes with a cost. An upgrade to one of these televisions may cost the buyer up to $4000. Yet, with the upgrade the viewer gains much intensity in action films and gaming. LED TVs are more efficient at creating excellent pictures of fast motions. The LED HDTV manufacturers also claim that television cuts energy consumption by 40%.

The close competition between LCD, plasma, and LED TVs leads to a need for great comparison from the buyer before making a final decision and purchase. While the plasma TV offers a great viewing angle, its reflective screen is often troublesome in light. LCD TVs work well for basic viewing needs but the bulbs do not compare to the newer LED TV creation. The newer LED TVs take the lead when it comes to the picture produced.

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.

It appears that LED has made its presence known in the world of electronics and does not intend to leave anytime soon. However, over time consumers should see reduction capabilities in the size of LED screens along with a reduction in cost.
