             The Difference of EDP & LVDS Panel

 

EDP is a kind of communication interface of computer display screen. The resolution of the computer using EDP display interface will be higher than the display resolution of LVDS interface. Generally, the high-definition screen uses this kind of communication interface, that is to say, you can achieve the function of a wide viewing angle.

 

Both EDP and LVDS are video signal interfaces, used in industrial computers to connect touch screens or displays. The LVDS interface utilizes a very low voltage swing (approximately 350mV) for differential data transmission over two PCB traces or a pair of balanced cables, ie, low voltage differential signaling. It is a digital video signal transmission method developed to overcome the disadvantages of large power consumption, large EMI electromagnetic interference, and the like when transmitting broadband high bit rate data in a TTL level manner. Industrial PCS use an LVDS output interface that allows signals to be transmitted at differential MPRs on differential PCB lines or balanced cables. Low-noise and low-power consumption are achieved by low-voltage and low-current driving.

 

The EDP interface is a fully digital interface based on the DisplayPort architecture and protocol. It can transmit high-resolution signals with simpler connectors and fewer pins, and can transmit multiple data at the same time. Therefore, the transmission rate is much higher On LVDS.
