LED (light emitting diode). It is a semiconductor light emitting diode control through the display mode, by gallium (Ga) and arsenic (As), phosphorus (P) and nitrogen (N), indium (In) compounds made of diode, when electrons and holes composite can radiate light, thus it can be used to make leds.

In the circuit and equipment as light, or of text or figures. Phosphorus gallium arsenide diode red glow, gallium phosphide diode hair green light, yellow light, silicon carbide diode indium gallium n diode

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, blue each gray level 256 16777216 colours, realization of LED electronic display shows rich colors, high saturation, high resolution, dynamic images of high frequency.

The basic principle of full color LED display color:

Every point on the CRT display, the display data are data contains three color: red (R), green (G) and blue (B), each color data with a 255 q integer O said, and when the R, G, B 255, shown as white; All are O, shown as black. LED display data from the PC graphics card, which is PC data output to the CRT. After the data output to the LED screen, as a result of the existence of green light with a yellow light, cause the distortion of LED display, including the purpose is to don't need to reduce the effects of yellow light as much as possible.

Full color LED display screen is clear, uniform color, high brightness, using high brightness LED, is still clearly visible over a long distance.

Full color LED display, a 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 to support multiple display mode.
