VESA Issues Embedded DisplayPort v1.3 Standard
The new standard includes an update to Panel Self Refresh, for improving mobile-PC battery life, and better control for the standard's 5.4-Gbps DisplayPort main link data rate.
The Video Electronics Standards Association (VESA) on Monday announced a new version of its Embedded DisplayPort standard: v1.3.
Embedded DisplayPort (eDP), a companion standard to the regular DisplayPort interface, is intended for use in netbook, notebook, and tablet mobile PCs, as well as all-in-one desktop systems. The new v1.3 includes a feature for Panel Self Refresh (PSR) intended to reduce system power usage, and therefore improve battery life in portable systems. (Portable PCs using the eDP v1.3 PSR feature are expected to be available by 2012.) In addition, eDP v1.3 also provides information on how to use the new 5.4-Gbps DisplayPort main link data rate (aka High Bit Rate 2, or HBR2).
According to a press release VESA released today, eDP is on track to replace the previous standard for LCD panel inputs, Low-Voltage Differential Signaling (LVDS), commonly known as VGA, which . VESA claims that major PC manufacturers such as Dell, LG Display, Lenovo, and Samsung have also committed to phasing out similar legacy technology in favor of digital interfaces like DisplayPort and HDMI in the near future.
The eDP v1.3 standard may now be purchased from VESA, and is provided for free to VESA member companies. For more information about VESA, visit the organization's Web site at VESA.org. To learn more about the DisplayPort v1.2 standard, read the ExtremeTech story, "."
