Almost everyone you know wants to own an LED TV simply because they came across advertisements about the latest technology that it uses and also because they all were taken in by the mumbo jumbo that the marketing representatives told them. The truth is that an LED TV is not about cutting edge technology or next generation television. It is simply an LCD TV that is backlit with LEDs or light emitting diodes in place of the standard cold-cathode fluorescent lights (CCFL).
When LCD TVs were first introduced there were some mutterings about its display output being not so good. There were issues about its ability to display colors in the right tone and also about its contrast features. However, when the LEDs were used instead of CCFL as a part of the effort to address the complaints raised by consumers, the display quality changed dramatically.
The LEDs are affixed to all the four sides of the TV and the light is projected inward to middle using light guides. The ability to dim portions of the screen and reduce the amount of light that reaches the darkened pixels makes the blacks areas appear more darker and visually more realistic. This is imperative to make the contrast features work at peak efficiency. Images become crisper and colors appear absolutely realistic.
With CCFL backlighting, it is impossible to get similar effects because the entire background dims or brightens uniformly and not selectively as the LEDs manage to achieve. Another major advantage is that LED backlighting can cut down on power use and make more efficient use of the panels than any other TVs available in the market. That is why LED TVs are miles ahead of LCDs in terms of performance and acceptability.
The edge backlighting technology has also made it possible to reduce the thickness of the TVs and make them slimmer. The new LED TVs are just about an inch in thickness and they produce stunningly clear picture quality and colors that are truly lifelike.
Continuous innovation in technology and advancement in LED techniques promise consumers a great time in the future in television viewing. There are some premium brands where LEDs are used innovatively. The words in a credit sequence of a movie can remain illuminated while the ones in the black background will remain dim.
LED TVs are expensive no doubt, but they offer true value for money with their remarkable viewing experience and crystal clear, sharp picture quality. Television viewing need not be a drab experience anymore.
