Outdoor full-color screen adopts red, green and blue light-emitting pipes. 256 grades of gray degree of every pipe forms 16, 777, 216 colors in all. Luminance is higher than 5000cd/ square meter.

Control system of full-color LED display screen is made up of the following three main parts:

1. Data Capture Card: The design adopts high-integration sampling control and storage circuit, which guarantees high reliability of the capture card. Can adjust chroma and contrast of each color via software. Can freeze pictures on the LED display screen via software and can also clear display of the LED via software.

2. Receiver Card: Receive data transmitted from the capture card and have point-by-point dynamic color compensation circuit.

3. Controller Card: Adopt the working way of full latching and static constant current, reduce heating of the system while raising luminance and effectively control the color temperature while restraining current fluctuation of the system.
