Edge Lit vs. Full Array For years Edge Lit TVs were the gold standard—and they're still the most common types of TVs available. They use LEDs placed along the edge of the TV, facing the center of the screen, t
2, the image to be displayed is first input into the local dimming system, then an image will be displayed on the screen by setting the luminance of the backlight array and light transmittance of the LC panel according to the input image. Based on the working principle of local dimming ...

The slopes of low and high gray regions for a global roll-off pixel-compensation are calculated based on average and maximum pixel values of a full image. Then, dimming values and pixel-compensation slopes for local blocks are extracted from average and maximum pixel values of full and local ...
