VESA Improves Device Battery Life and Performance with Embedded DisplayPort 1.4
 

The Video Electronics Standards Association (VESA) today announced the upcoming release of Embedded DisplayPort (eDP) Version 1.4. This version of VESA's embedded display interface includes new features that will further reduce system power consumption, support multi-touch data over the display interface, and support a wider range of platform topologies including tablets, handheld devices, and notebook PCs. These new features will position eDP as the universal embedded display interface for mobile devices and will lead to increased battery life, reduce system size and weight, as well as increase overall display capabilities.

eDP v1.4 addresses system power reduction through new features, including a new partial-frame update capability for Panel Self Refresh (PSR), lower interface voltage swings, additional link rate options, transport data compression, and regional backlight control. The auxiliary channel will now carry multi- touch data from the display to system processor. eDP v1.4 electrical interface parameters have also been enhanced to accommodate a wider range of system form factors and transmission media.
