The world’s largest LED TV is the 60 inch Sony Bravia EX700. This is bigger than the standard 55 and 56 inch sets sold. The smaller ones are around 32 inches.
LED stands for light emitting diode. This is a type of LCD (liquid crystal display) TV with LED backlighting. This is in contrast with the usual fluorescent tubing used.
This type of TV must not be mistaken for the OLED (organic light emitting diode) variant. That is a TV with its own electroluminescent layer made up of organic compound film. The OED TV does not need a backlight. As a matter of fact, the term “world’s largest LED TV” is somewhat inaccurate because it is actually an LCD TV.
LED backlighting is superior to fluorescent lighting. The problem with the latter is it leaks a bit. This limits the TV’s capability of displaying black. Fuzzy images may also appear. Fluorescent lighting also suffers from lack of color saturation. It is due to these deficiencies why LED lighting was developed.
Two types are available: Edge LED and RGB LED. In the former, the TV’s edge is lined with the diodes. This permits casing as thin as one inch.
TVs with RGB Dynamic LEDs have the diodes scattered around the whole panel. This improves the television’s ability to distinguish between light and dark areas. But as technology improves, the difference between the two LED types is narrowing.
Comparisons with Plasma
LED and plasma TVs are both used to make flat screen TVs. Traditionally, plasma TVs have been more affordable than LED. The latter’s advantage is that they are more efficient energy-wise.
The first LED TV sold was the Sony Qualia in 2004. It utilizes the RGB LED lighting system. It would prove popular and be incorporated into other models.
Numerous features are now being added. With quantum dot technology, Gaussian light distribution is improved. The results are superior images. Other features are now being implemented as competition is very tight.
Anyone who wants to buy a set should conduct some research first. It is very easy to get lost in all the technical jargon. Understanding what the TV can and cannot do is therefore essential.
When looking for the world’s largest LED TV, don’t forget that it is an LCD TV. Don’t get confused if store personnel refer to it as such. That is a fact that all would-be buyers should keep in mind.
