VESA publishes the eDP 1.5 standard, adding new features and improving existing ones

VESA (Video Electronics Standards Association) recently announced a new version of the embedded DisplayPort standard, eDP 1.5. Compared with eDP 1.4, which was introduced in 2015, eDP 1.5 adds and updates many features, such as adding new features to the variable refresh rate protocol and improving power consumption. For small computer devices such as laptops or all-in-one computers, eDP is the interface used to transfer video output signals from graphics hardware to the built-in display.

This updated eDP 1.5 standard first made improvements in terms of energy savings, this new standard now supports panel self-refresh, static images can be temporarily stored in the display storage, while other components can enter a low-power standby state, the system can wake up at any time as needed to refresh all or part of the display area. In addition, eDP 1.5 has added a new protocol, including allowing the display operator interface to be disabled during normal operation during the vertical sweep period to further reduce power consumption.

As for the games and media playback that everyone cares more about, the eDP interface has long supported variable refresh rates, and this time eDP 1.5 has added new features to it. For movie and streaming playback, the new protocol in eDP 1.5 allows it to make small adjustments to the frame rate of the frame, thereby preventing frame skipping or repeating frames. For a computer or laptop that plays the main game, this new mechanism can effectively reduce screen flickering.

Like the general DP interface, eDP 1.5 will continue to support VESA's DisplayHDR and DisplayHDR True Black standards, providing players with a more vivid and contrasting picture.
