LED full-color display usually adopts synchronous display system, which consists of sending card and receiving card. The outdoor display area is below 80 square meters and usually uses one sending card and 40-50 receiving cards (two boxes and one card). Indoor LED full color screens are more expensive due to higher pixel density.
Note: That is, the cost of sending and receiving cards on the display screen, generally only one sending card is required for one screen, and it is installed in the host computer, and the number of sending cards is n. The use of the control card is mainly based on the size of the display to determine the number. Generally speaking, the larger the area and the higher the density of the display screen, the more the number of receiving cards used.
3, accessories
The electronic display should work normally, and also need many accessories, such as computer (desktop computer), air conditioner (heat dissipation), lightning arrester, power distribution cabinet, audio amplifier (optional), TV card (optional), multi-function card (automatic Adjust the physical data such as display temperature, brightness, humidity, etc.), video processor (optional), etc. The spreads of accessories of different brands are very large, and customers can also purchase them locally.
Note: Control computer: necessary equipment to control LED display, need configuration requirements or higher: dual-core CPU, 2G memory, 512M or more discrete graphics, motherboard must have PCI slot.
Audio + Amplifier: A device that allows the display to synchronize the sound of video playback. It is usually equipped with 1 amplifier and 2 speakers.
Power distribution cabinet: small-area LED display can be used; it is recommended that the maximum power consumption is above 10KW power display, which can provide stable voltage supply current for each device of display device, effectively preventing the display power supply from switching. malfunction.
Air conditioning: heat dissipation equipment, outdoor LED display above 20m2 must be configured by the manufacturer air conditioning to ensure the normal operation of the screen and extend the life of the display devices. Generally, the indoor screen or small-area display can be used; the large-area indoor display is strongly recommended to be equipped with a wall-mounted air conditioner to effectively cool down, ensure the normal travel of the display at high temperatures, and reduce the failure rate.

The intelligent adjustment can save energy and save the life of the led display; the indoor display can be used.
