LED TVs have proven themselves well and are wildly popular. The cost of such TVs is gradually falling, but even now not everyone knows how these TVs differ from other models and what they are.
LED TVs
LED TV is a LCD TV that uses LEDs to illuminate it. For example, other LCD TVs that came before used a cold cathode to illuminate the screen. It is believed that it is LED TVs that have the best picture quality, unlike previous TV models, namely: color quality, contrast, color depth, brightness and other parameters.
Image quality is affected by a new technology called local dimming. This technology is responsible for local dimming of the screen, due to which the picture quality is increased several times. Unfortunately, this technology has some drawbacks, for example: poor color uniformity in the image, color halos may appear on contrasting transitions, and some of its details may disappear in the dark areas of the image.
Varieties of LED TVs
It is worth noting that LED TVs are divided into two subtypes according to the way the LEDs are arranged, these are: Direct and Edge. Direct means that the LEDs are evenly located behind the screen, and when using Edge technology, in turn, the LEDs will be located around the entire perimeter of the screen, together with the diffusing panel.
Each of these technologies has its own advantages and disadvantages. For example, Direct, allows you to get a more uniform backlighting, but this will increase the thickness of the screen itself, and therefore the TV, and in addition, the power consumption will increase. This is because the number of LEDs increases with this method. Thin or ultra-thin TVs are built with Edge technology, which is the exact opposite.
As mentioned above, the cost of LED TVs is decreasing today. This is due to the advent of TVs with advanced IPS technology. Such TVs have better color reproduction than LED TVs, high brightness and contrast levels, high image definition and many other advantages.
As a result, choosing a TV by the type of backlighting, a person can make a mistake, since it does not always have a decisive effect on the image quality. An important role in this is played by the type of GPU, as well as the image processing technology.
