The Utility of Technology

Posts Tagged ‘LED Technology’

As a consumer, looking into buying a television, it can be confusing to sort out the information given by manufacturers. The newest technology, for example LED, is highly touted over current the industry standards, like LCD or plasma because they want you to buy the newest stuff. It’s an odd series of mixed messages you go through so that information is presented in the same order that they want you to consider buying. Of course that starts with the top of the line and works down. Albeit that the top of the line currently is the best option to buy for numerous reasons, it is still time to get all the confusion cleared up.

LED televisions are not different from LCD as much as they’re a development of it. The first, and still popular LCD televisions, are a liquid crystal display that uses a cold cathode fluorescent backlighting. With the introduction of LED technology for backlighting, instead of CCF, televisions have been much higher in quality. They are better with color contrast, brightness and higher quality blacks, which is an industry benchmark. They are also lighter and use as much as forty percent less power. The first LED backlight televisions used all white light diodes. Now, as the technology develops, colored light emitting diodes are used to enhance the job of the LCD.

This addition to LED backlight technology was introduced around 2005. Since then, LED has contributed quite a bit to the color presentation, making even better color contrasts and quicker transitions between pictures. Using colored diodes also cuts down on color bleed because much more control is retained at the light source.

From a buyer’s perspective, it will come down to price. The LED backlight televisions are more expensive than the CCF TV’s. Though it may happen, as other emerging technologies get developed, LED has not replaced florescent backlighting. This means that when you go check television makers you sill still see several options with CCFLCD. These and plasma televisions are the most purchased types right now. LED backlight is now the most prominent display in today’s tablet computers.
