According to the color principle, know red R, green G, blue B is called the three primary colors. These three colors can be combined to get any color from black to white. LED display category, a monochrome display, two-color display, full-color display. Monochrome is relatively simple, only need to choose any one of the three primary colors to achieve monochrome display. In practice, select more red LED lights. In this case, a red LED light is a pixel.
Two-color display and monochrome display is more or less the same, as long as the choice of three colors in any two colors to achieve two-color. In practice, choose more red and green. When the red and green light at the same time, you can achieve yellow. Therefore, two-color display can be red, green, yellow 3 colors.
Monochrome display LED lighting is the use of solid semiconductor chips as a light-emitting material in the semiconductor through carrier recombination emission of excess energy caused by photons emitted directly to the red, yellow, blue, green, green, orange, purple, white Light.
Full-color LED display to show a wide range of colors, so you need to be able to show the different colors from black to white. Therefore, full-color LED display requires red, green and blue lights together to form a pixel, in order to show a wide range of colors. Full-color LED display, is divided into real pixel display and virtual pixel display. Both use different display technologies, so the composition of pixels is not the same.
