led screen panel

The LED screen panel as a new show media, is a collection of photoelectric and computer technology in the integration of high-tech products. Along with large scale integrated circuit and the rapid development of computer technology, obtained the rapid development, has been widely used in many fields.

In LED display system, most used for transmission, processing, control signal are digital signal, but most current between computer and external display device is through simulated VGA interfaces connected with digital mode, internal computer generated by the display card image information, the D/A (digital/simulation) converter changes for R, G, B tricolor signal and line, field synchronized signal transmission to by cable, signal display device. For analog display devices, such as analog CRT monitor, signal is sent directly to the corresponding processing circuit, drive control tube produce images. And for LCD, DLP display device, such as digital display device which need to configure corresponding A/D (analog/digital) converter, analog signal into A digital signal.
