LED television expertise is way different. A light shines behind teams of crystal pixels set in a box like grid pattern. Each pixel has three sectors with each one of the three major colors. The light that shines from behind the grid will shine by way of to the front of the screen if not controlled in some manner. An electronic gate controls how much light can shine by way of each of the pixel grid areas. This determines the amount of light and shade that’s visible on the LED television screen.
