Several LEDs form a display cell called pixel which is responsible for color reproduction and brightness in the design of the LED module. It is a basic point consisting of three primary colors (R-red, G-green, B-blue), on which a full color image is written with the help of a pixel. Pixels are combined into modules that make up the LED display. LEDs on large screens match the pixels. Just like on a regular TV. Although every pixel is noticed when looked closely, at long distances these pixelsare not noticed and form a quality whole.
