The important color of LCD is of course the degree of color expression. We know that any color in nature is composed of three basic colors: red, green, and blue. The LCD panel is composed of 1024×768 pixels. Each independent pixel color is controlled by three basic colors of red, green, and blue (R, G, and B). The liquid crystal display produced by most manufacturers reaches 6 bits for each basic color (R, G, B), that is, 64 kinds of performance. Many manufacturers also use the so-called frame rate control (FRC) technology to display full-color images in an emulated manner. That is, each basic color (R, G, B) can reach 8 bits, that is, 256 performance degrees. .
