EDP interface is a communication interface for LCD screens. LCD screens that generally use EDP interface have higher resolution, and high-definition LCD screens all use EDP communication interface. Today, the editor will focus on explaining what the EDP interface in LCD screens is, hoping to be helpful for everyone to understand the high brightness LCD screen:
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 achieve simultaneous transmission of multiple data. Therefore, its transmission rate is much higher than LVDS. Next, let's talk about the characteristics of the EDP interface in LCD screens:
Characteristics of EDP interface in LCD display screen:
1. The micro packet structure enables simultaneous transmission of multiple data.
2. No need for LVDS conversion circuit, the circuit is simple.
3. Small EMI (electromagnetic interference) and strong copyright protection function.
After reading the above description, many friends may still have doubts. Let's take a color LCD screen with a resolution of 1920x1200 and 24 bits as an example. If LVDS interface is used, 20 pairs of data transmission lines are required; If using EDP interface, only 4 pairs of wires are needed. It can be seen that the advantages of EDP interface are quite obvious, especially in high-definition screens. In recent years, in order to improve the data transmission speed between panels and processors, EDP interfaces have been widely used in industrial control computers and tablets, and EDP interfaces are rapidly becoming the mainstream interface.
