VESA Embedded Display Port 1.4, improves battery life for all types of devices

Posted in: Today's Chili

The Video Electronics Standards Association(VESA) has updated the specifications of its embedded Display Port to 1.4 with changes aimed at saving power usage for all types of devices. In a previous update, VESA had introduced a feature called Panel Self Refresh (or PSR) that freed the computer graphic sub-system from having to constantly send image information for static images. Better yet, the graphics processor could in theory be turned OFF. That meant that static images do not consume power on the computer side, but only on the display side. (more…)

VESA announces embedded DisplayPort Version 14, claims better battery life and performance improvements

The embedded DisplayPort (eDP) standard consumes less power than the on-the-way-out LVDS method, and a new update from VESA should cut down on energy usage even more. The reduced power-sipping comes thanks to a new partial-frame update feature for Panel Self Refresh, regional backlight controls, additional link rate options and other tweaks. The upcoming release of eDP Version 1.4 will also support a wider range of mobile devices, including tablets, laptops and “handhelds,” and the auxiliary channel can now carry a display’s multitouch data to the system processor. Additionally, VESA says this latest version of eDP will allow for increased battery life and allow for thinner, lighter devices. Look for the standard to be released in October, and it should make its way to gadgets by 2014.
