: Utilizing the HBR3 (High Bit Rate 3) link rate, it supports up to 8.1 Gbps per lane. With four lanes, it provides a total theoretical bandwidth of 32.4 Gbps (25.92 Gbps effective payload). This allows for: 8K resolution at 60Hz. 4K UHD at 120Hz with 10-bit color. 5K resolution at 60Hz with 30-bit color.
The EDP 1.4 specification introduces several key features that enhance the performance and capabilities of display interfaces. Some of the notable features include:
The eDP 1.4 specification was a landmark achievement that successfully bridged the gap between high-performance external DisplayPort standards and the unique power and form-factor requirements of embedded devices. By introducing innovations like HBR3, DSC, and PSR, it enabled the modern era of high-resolution, battery-efficient laptops and tablets.

Below is a comprehensive guide to understanding the features, architectural enhancements, and engineering benefits detailed within the eDP 1.4 specification. Overview of Embedded DisplayPort (eDP) : Utilizing the HBR3 (High Bit Rate 3)
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
If you open the eDP 1.4 specification PDF, you will find these 6 core features dominating the chapters. Understanding these is essential.
Embedded DisplayPort is a standardized internal display interface that connects a device's graphics processing unit (GPU) or system-on-chip (SoC) directly to its internal LCD or OLED display panel. It built upon the foundations of the external DisplayPort standard but introduced unique, power-saving features tailored specifically for embedded architectures. eDP effectively replaced the older, bulkier Low-Voltage Differential Signaling (LVDS) standard, which could no longer keep pace with high pixel densities and strict power budgets. Core Objectives of the eDP 1.4 Specification
The release of the eDP 1.4 specification directly enabled the modern generation of slim, long-battery-life computing hardware: 4K UHD at 120Hz with 10-bit color
Searching for an usually means you are an engineer, system designer, or hardware enthusiast looking to understand implementation details, electrical characteristics, or bandwidth capabilities. Architectural Breakthroughs in eDP 1.4
At its heart, eDP 1.4 focuses on three primary goals: reducing power consumption, minimizing physical space (wire count), and enhancing data throughput. Unlike external DisplayPort connections, which require standard connectors and cables, eDP is "embedded," meaning it is integrated directly into the device's internal circuitry.
