Television manufacturers continue to work to create a better and more pleasing viewing experience for consumers. The new craze in film watching and TV gaming opens up the TV electronic world to discover more realistic pictures through color perfection and clarity. Through this venture, many different types of bulbs and lighting sources have been tested and tried. While many have shown great success, the desire for even better continues. The newest discovery being Light Emitting Diode (LEDs) in the LED high definition television.
From the trial of using LEDs for color and clarity in screen projection has evolved the LED television. LEDs are better than fluorescent or incandescent bulbs at directing light in a single direction. These television have much the same features as LCD TVs except that they make use of LEDs. The LEDs are either placed along the outer edges of the screen or across the back of it. Television with perimeter LEDs are edge-lit and televisions with LEDs in the back are back -lit.
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.
When looking at terms associated with a LED screen, the word high definition will likely arise. All LED TVs has full high definition but not to the same degree. The LEDs in a LED screen combine to form little pixels or dots that contribute to the visual output. These red, blue, and green pixels work together to form all other colors including white. On some screens, a group of 9000 LEDs may be located within any one meter. In this case, the LEDs would be close together with a small pitch, space between them. A TV with a small pixel pitch has higher definition than screens with larger pixel pitch.
The LED monitor has also broken ground in the electronics world. While many were happy with their flat panel LCD monitor, the color produced simply did not satisfy manufacturers. The LED monitor out produces the LCD model when it comes to creating accurate and precise color. However, this beautiful color does not come without cost. NEC has the first LED monitor with a high end price range of over $6000. In addition to displaying perfect color, the company also contributes part of its creation to the fact that Mercury is found in fluorescent backlights. Afraid of upcoming strict shipping restrictions, they claim to have made an environmental decisions as well as a color one.
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.
