Embedded DisplayPort Reaches 1.4a

Print

The Video Electronics Standards Association (VESA) publishes the Embedded DisplayPort (ePD) standard version 1.4a-- a replacement to the February 2013 eDP v1.4 bringing an increase in video data transfer rate.

ePD 1.4It incorporates the VESA Display Stream Compression (DSC) standard 1.1, as well as a segmented panel architecture allowing for higher panel integration.

Leveraging on DisplayPort 1.3 as base specification, eDP 1.4a operates at the HBR3 link rate of 8.1Gbps per lane (for maximum bandwidth of 32.4Gbps), allowing it to support 8K resolution displays. Another addition is Multi-SST Operation (MSO), a technology supporting Segmented Panel Display, a VESA display architecture for thinner, lighter and lower-cost display panels.

MSO also allows the division of the 4 high-speed data lanes within the ePD interface into either 2 or 4 panel segments, allowing for higher level of integration on high-resolution displays.

The standard is already available to VESA members, and the association says displays with eDP 1.4a support should ship by 2016.
