8, P5, P8, P10, etc.
Outdoor LED display, outdoor LED display is mainly used for outdoor, in the process became the first light-emitting grain encapsulated into a single light-emitting diode, called single lamp, single lamp is generally used to make outdoor screen reflective cup has concentrated effect is used to improve the brightness;
Again by more than the LED single lamp is encapsulated into a single pixel tube or pixel module, and is composed of pixels or pixel module matrix display unit cabinet, according to user needs and application of a place, with a display unit housing as the basic unit of the size of the you need.

Full color LED display full-color LED display is red, green, blue three kinds of LED tube together as a single pixel of LED display.
Full-color LED display, also known as the three primary colors, each pixel has red, green, blue three primary colors, with the help of gray scale control, through the different gray level changes, red, green and blue is a good way to restore the color of nature, combination of 16777216 colors.
