Recently, many have been worried about the question of what is an LED TV? These units have proven themselves well and have managed to gain widespread popularity. The cost of this type of TVs is gradually decreasing, making them much more affordable. Not everyone understands what an LED TV is, so it is worth understanding the principle of its operation, discussing the pros and cons associated with the production technology.
In fact, this device is a TV on which the screen is backlit by means of LEDs. Earlier LCD TVs used cold cathode lamps. It is worth mentioning the advantages of using an LED matrix in the backlight. Manufacturers are talking about a significant increase in image quality. There are a number of parameters that have a direct impact on how viewers perceive an image. It is customary to refer to them as brightness, contrast level, black depth and color rendering quality. In most cases, LED TVs are significantly ahead of their counterparts.
If we talk about what an LED TV is, then it is worth saying that the mentioned feature is associated with design features.When adjusting the level of the diode glow, it is quite possible to achieve absolute control over the lighting or darkening of certain areas of the screen. In the off state, the LED does not produce any glow, therefore the group of off diodes creates completely black areas. This technology achieves deep blacks and excellent contrast levels. The overall color rendition also becomes significantly better, which has a positive effect on image quality. Thanks to the glow of LEDs, LCD LED TVs have a high screen brightness. The use of a diode matrix allows you to make most of the parameters that are responsible for the output of a high-quality image much better. The significant reduction in energy consumption is another major plus.
Speaking about what an LED TV is, it should be mentioned that no harmful aerosols and mercury are used in production, and this has a beneficial effect on both single-color and tri-color diodes can be used in LED backlighting, which can significantly increase the number of displayed colors ... It is generally accepted to use white LED backlighting, which reduces the risk of image problems.
Manufactured using "local dimming" technology, which is responsible for local dimming. According to it, the LEDs are controlled by groups consisting of several separate elements. The disadvantage of this technology is the possibility of poor uniformity in the displayed image. This is usually the appearance of bright spots in areas with a brightly turned on backlight and dark spots where the backlight is completely off.
