Edp 1.4 Specification Pdf Jun 2026

The VESA eDP 1.4 standard introduced a suite of powerful features that fundamentally redefined what was possible for internal display interfaces.

The technologies within eDP 1.4 translate directly into practical advantages for end-users and manufacturers. The standard supports resolutions up to 8K (7680x4320) at a 60Hz refresh rate and enables superior color depth and dynamic contrast with official support for VESA's DisplayHDR and DisplayHDR True Black specifications. By reducing power draw, the standard helps extend the battery life of mobile devices, while features like MSO and DPO allow for thinner, lighter designs and more streamlined system architectures.

When the screen image stops changing, the GPU tells the TCON to refresh the display locally from its own buffer. The GPU and the high-speed main data link then drop into a low-power sleep state, slashing system-wide power consumption. edp 1.4 specification pdf

eDP 1.4 supports standard DisplayPort data rates up to HBR2 (High Bit Rate 2), alongside custom intermediate link rates optimized to reduce power and EMI: Link Rate Designation Speed per Lane Max Bandwidth (4 Lanes) HBR (High Bit Rate) 10.80 Gbps HBR2 (High Bit Rate 2) 21.60 Gbps

A: No. Because eDP is for embedded connections (traces on a PCB or short flex cables), the spec does not cover user-replaceable cables. For that, see the standard DisplayPort cable spec. The VESA eDP 1

Panel Self Refresh (PSR) allows the display panel to refresh its own frame from its own local memory when the computer is displaying a static image (e.g., reading a document).

The is more than just a technical document—it is the key to building displays that are simultaneously high-resolution, power-efficient, and responsive. Whether you are designing the next generation of ultrabooks, medical monitors, or automotive touchscreens, mastering this 200+ page standard will give you a competitive advantage. By reducing power draw, the standard helps extend

Fewer lanes translate directly to smaller connectors, thinner cabling, lower system cost, and reduced EMI. Advanced Link Power Management (ALPM)

Supports higher bit-depth color, providing better image quality for photo and video editing. eDP 1.4 vs. Previous Versions (1.3) eDP 1.4/1.4a Max Link Rate HBR2 (5.4 Gbps) HBR3 (8.1 Gbps in 1.4a) DSC Support Yes (DSC v1.1/1.2) Segmented Panel Power Management Advanced PSR/PSR2 Obtaining the eDP 1.4 Specification PDF
