The Video Electronics Standards Association (VESA ) announced today that it has published the Embedded DisplayPort (eDP) Standard version 1.5. Replacing eDP 1.4b, published in 2015, eDP 1.5 retains all key features of the previous specification while adding additional capabilities and performance. These include an improved panel self-refresh protocol coupled with enhancements to VESA’s Adaptive-Sync protocol, a combination that results in added power savings and improved motion image quality.
For devices such as laptop PCs with an embedded display, eDP is the electrical interface for transporting video data from the system’s graphics hardware to the internal display panel. eDP is widely adopted for larger, higher-resolution displays as it provides the highest resolutions, refresh rates and color depths using a low wire count with low EMI radiation. Enhancements to the eDP standard have continued since its introduction more than 10 years ago, thanks to contributions by major OEMs through the VESA organization. eDP applications include laptops, all-in-one PCs, premium tablets, automotive displays, and other systems that incorporate a display panel with a video or graphics video source.
