The eDP interface is a fully digital interface based on the DisplayPort architecture and protocol. It can use simpler connectors and fewer pins to transmit high-resolution signals, and can achieve simultaneous transmission of multiple data. Generally, the EDP interface is used LCD screens have higher resolutions, and high-definition LCD screens all use EDP communication interfaces.
What are the advantages of the eDP interface?
1. Easily handle large amounts of data
The high bandwidth provided by eDP (up to 32.4 Gbps, depending on version) enables it to transfer large amounts of data, supporting high resolution (e.g. 4K, 8K) and high refresh rate (e.g. 120Hz, 144Hz) display needs. High bandwidth enables more pixel data to be transferred simultaneously on a single connection. In addition, the multi-channel support function allows users to configure multiple channels as needed to increase data transmission capabilities. By increasing the number of channels, eDP can significantly increase the overall bandwidth to better accommodate high-resolution and high-frame-rate display needs.
2. Simplified connection architecture
eDP uses fewer pins and simpler connectors, which helps reduce signal interference and delay and improve the efficiency of data transmission. Simplified connections also facilitate the design of more compact devices. In addition, the main reason why eDP is widely adopted by many major display manufacturers and mobile device manufacturers is that eDP can enhance interoperability between various types of devices, especially in laptops, tablets and other embedded devices.
3.Compatibility
It can be backward compatible, that is, eDP can be backward compatible with the LVDS (Low Voltage Differential Signal) display interface. We can use a specific conversion solution to allow older devices to use eDP’s new technology. In addition, eDP supports various extended functions such as DSC (Display Stream Compression), DSC 1.2a and panel adaptive adjustment, etc., providing better image quality and responsiveness, which are usually required in high-resolution displays.
High-resolution displays are particularly important in various application scenarios due to their excellent image quality and user experience. Therefore, eDP is an ideal interface choice for high-resolution display applications due to its high bandwidth, low power consumption, flexibility and support for advanced features. Overall, eDP’s compatibility makes it an ideal choice for high-resolution display applications, meeting diverse display needs while ensuring good interoperability between devices.
