5 Embedded Display Port

Embedded DisplayPort (eDP) is a high-performance audio/visual interface developed by the Video Electronics Standards Association (VESA). eDP is an advanced version of the DisplayPort interface, specifically designed for embedded systems such as laptops and all-in-one computers.

eDP's key advantage lies in the efficiency and high-resolution support. eDP uses fewer pins than LVDS, reducing the complexity and size of the connectors. This efficiency is coupled with advanced power saving features such as panel self-refresh (PSR), which allows the system to save power by not refreshing the screen when the image is static.

eDP also provides support for higher resolution and color depth compared to LVDS and DSI, and can carry audio, video, and USB signals over a single cable. However, eDP might not be designed for smaller, low-power devices that do not require high-resolution displays.
