Let the manufacturer to answer for us: full color led display is a kind of led display, color is rich. By the three primary colors ( Red, green, blue) Display unit of red, green, and blue gray level 256, all 16777216 colors, make electronic screen shows rich colors, high saturation, high resolution, high frequency of dynamic images displayed. Full color led display screen is clear, uniform color, high brightness, using high brightness led, is still clearly visible over a long distance. The effect is good; Using nonlinear correction technology, image more clear, administrative levels feeling stronger; Reliability: the distributed scan technology and modular design technology, higher reliability, stability; Full color led display gradations of color is gray or gray, is refers to the brightness of light and shade degree. For digital display technology, gray level is to display the number of color. In general gray level is higher, the screen showed the more colorful, the picture is more exquisite, more abundant details. Full color led display gray level mainly depends on the A/D conversion system. Of course system of video processing chip, storage and transmission system to provide all the support of the digits. At present domestic LED display mainly adopts eight processing system, namely 256 ( 28) Grey level. Simple understanding is a total of 256 from black to white brightness changes. Use RGB trichromatic can constitute a 256 x 256 x 256 = 16777216 colors. Known as the 16 million colors.
