embedded DisplayPort (eDP)

Embedded DisplayPort (eDP) is the DisplayPort variant for tablets, notebooks and all-in-one PCs. eDP replaces Low Voltage Differential Signalling (LVDS) and supports the display resolutions 4K and 5K by High Bit Rate (HBR) and by compression of the data stream.

The compression is done with Display Stream Compression (DSC). Version 1.4a also supports 8Kdisplay resolutions with a refresh rate of 60 Hz. Transmission is on four eDP channels at High Bit Rate (HBR).

The various versions of eDP that have been standardized since 2008 relate to the internal connection between the graphics card and notebook display, power consumption reduction, refresh rate, 120 Hz refresh rate, display control protocol, Panel Self Refresh (PSR) and higher bit rate.
