How the screen dimming system works
The principle of operation of the screen dimming system in LED TVs is quite simple. The TV screen consists of pixels of polarized crystals that, when a certain voltage is applied, turn and pass light through themselves. An algorithm has been developed that compares what voltage is applied to the crystals and, depending on the voltage and the number of pixels that are closed in a certain area, turns off the backlight of this area of the screen.
