LED TVs over their predecessors.

 

 

LED TVs…

Entertainment remains one of the driving forces of scientific progress.

Electronic makers invest a lot in the development of new state-of-the-art technologies.

LED TVs are one of the recent achievements of the modern-day electronic industry. Will LED eventually replace LCD and plasma TV sets?

There is a whole range of new devices that contain ‘LED’ abbreviation in their titles.

There are several types of displays which are based on light-emitted diodes – LED. However, sources of light play different roles in each of those types.

In OLED, AMOLED and OEL displays, every pixel corresponds to a tiny diode. Electric current is delivered to each and every element of the display to create the full spectrum of colors in a picture.

Such devices are very expensive, small and they do not last long.LED TVs

In LED TVs, diodes play a different role.

As a matter of fact, they are conventional LCD displays, in which high brightness diodes are used for backlighting instead of fluorescent lamps.

The use of the reliable LCD technology allows to produce quite large LCD TV sets – up to 55 inch screens for home use and larger screens for industrial use.

LED TVs take advantage over their predecessors, LCD TVs, from the point of view of color rendering.

It was never possible to realize the real black color in LCD screens because of the light produced by cold-cathode lamps.

No company in the world has managed to get rid of the shortcoming. In addition, the white light wave length complicates the rendition of many color shades, which eventually worsens the image perception.

LCD TVs will most likely be replaced in the future due to their high energy consumption and short durability. LED TVs have none of the above-mentioned drawbacks.

There are two basic types of backlighting used in the new TVs to create high-quality images – Direct LED and Edge LED. Such TVs offer the most distinct picture, but they cost more because of the use of a large number of diodes.

Another advantage of a LED TV is its thinness. The thickest spot of a LED TV is normally 3 centimeters.

For the time being, LED TVs have only one drawback – their price. Experts say, though, that prices on such TVs will begin to decline with the development of their production and new models.
