What Is eDP Interface In LCD Monitor?

EDP interface is a kind of communication interface of LCD monitor. Generally, the LCD monitor with eDP interface has higher resolution, and the high-definition LCD monitor often use eDP communication interface. Then what is the eDP interface in the LCD monitor ?

EDP interface is a fully digital interface based on DisplayPort architecture and protocol. It can transmit high-resolution signals with simple connectors and few pins, and support transmit multiple data at the same time, so its transmission speed is much higher than LVDS. It is suitable used in tablet PCs, laptops, all-in-one computers and future mobile phones with large screen and high-resolution.

Features of eDP interface in LCD monitor:

1. The micro packet structure realize the simultaneous transmission of multiple data.

2. No need LVDS conversion circuit, and the circuit is designed with simple layout.

3. Tiny EMI (electromagnetic interference) and powerful copyright protection function.

After reading above description, you may still feel confusing, let's give an example, take the 1920x1200, 24bit color LCD as an example. If LVDS interface is used, 20 pairs of data transmission wires are needed; if eDP interface is used, only 4 pairs of wires are needed. It can be seen that the advantages of eDP interface are quite obvious, especially in high resolution screen. In recent years, in order to improve the data transmission speed between panel and processor, eDP interface has been widely used in industrial PC and industrial tablet PC, and eDP interface is rapidly becoming the mainstream interface.
