The Video Electronics Standards Association (VESA) has announced a new version of the eDP standard with new features and protocols, including improved adaptive sync support, which is expected to lead to more advanced power optimization for display devices.

VESA announced on the 4th that it is announcing a newly enhanced version 1.5 of the eDP (Embedded DisplayPort) standard.

eDP 1.5 replaces eDP version 1.4b, which was released in 2015, and retains all the features of the previous standard while adding new features and improving performance.

This includes reduced power consumption and improved motion image quality through a combination of improved panel self-refresh protocols and VESA's Adaptive-Sync protocol.

For devices such as notebook PCs with built-in displays, eDP is the electrical interface that transfers video data from the system's graphics hardware to the display panel.

eDP is widely adopted for large-screen, high-resolution displays due to its advantages of achieving high resolution, refresh rate, and color depth with low EMI emissions using fewer wires.

eDP has been around for over 10 years and has evolved over the years thanks to the contributions of many members of VESA.br />
eDP applications can be used on any system equipped with a display panel to provide video or graphical video, including notebook PCs, all-in-one PCs, premium tablets, automotive displays, and others.

Like previous versions, eDP 1.5 supports panel self-refresh as one of its key power-saving features.

With panel self-refresh, static screen images are stored in display memory while the rest of the system enters a low-power standby state. The system can then wake up immediately to update the display, either fully or partially, when needed.

Other new features in eDP 1.5 include the ability to disable the display interface during vertical blanking periods during normal operation, which also saves additional power. eDP 1.5 also supports new panel types, such as OLED panels, which have a long screen life, allowing for lower refresh rates and eliminating the need for a frame buffer.

Like its predecessors, eDP 1.5 also supports VESA’s DisplayHDR and DisplayHDR True Black features, which enable vivid, realistic high dynamic range (HDR) content with excellent color and contrast in embedded display applications.
