Raw Bandwidth=4 lanes×5
The official eDP 1.4 specification is developed and managed by VESA. The complete technical standard document is usually available to VESA members.
Register mappings for DisplayPort Configuration Data (DPCD).
This article explores the core features, advantages, and technical aspects of the eDP 1.4 standard. What is eDP 1.4? The EDP 1
The physical topology of an eDP 1.4 link consists of high-speed differential pairs utilizing low-voltage AC-coupled signaling. The architecture is split into three distinct channels:
: The standard added support for newer technologies like certain OLED panels, which feature extended display persistence and can operate with a low refresh rate without needing a frame buffer, further saving power.
4 Lanes of Main Link, 1 AUX Channel, dedicated lines for PSR2 synchronization, expanded power paths for high-nit backlights, and secondary data buses. 5. Industrial and Commercial Value
High-resolution panels can be supported with fewer lanes, reducing costs and power.
The eDP 1.4 standard introduced several breakthrough technologies aimed at reducing system power consumption while drastically increasing data throughput.
