Embedded DisplayPort Technology

eDP Interface Displays

High-performance industrial displays utilizing Embedded DisplayPort (eDP) interface standards. Designed as the modern successor to legacy LVDS systems, our eDP panels transmit high-bandwidth video data up to 5.4 Gbps per lane over ultra-thin micro-coaxial cables. Supporting resolutions up to 4K, integrated panel power rails, low power states like Panel Self Refresh (PSR), and robust noise suppression (ASSR), these displays connect directly to high-end x86 and ARM processor boards.

Premium eDP interface design advantages

High-Speed eDP Bus

Based on the DisplayPort protocol to support high refresh rates, rich pixel depth, and deep colors over 1, 2, or 4 lanes.

Micro-Coaxial Cabling

Uses high-shielded, flexible micro-coaxial ribbon cables with a 0.5mm pitch to reduce space and system weight.

Anti-EMI Layout

Incorporates Alternative Scrambling Seed Reset (ASSR) and low voltage swings to minimize EMI fields.

Panel Self Refresh

Saves power during static display states by running the panel directly from the onboard PSR frame buffer.

Integrated Logic & Power

Single micro-coaxial cable carries the eDP video lanes, auxiliary (AUX) control pins, logic power, and LED backlight rails.

Multi-touch PCAP Lamination

Integrates Projected Capacitive (PCAP) multi-touch panels with direct USB-HID and I2C host communication.

Modern successor to legacy LVDS buses

Advanced high-bandwidth internal routing

Embedded DisplayPort (eDP) has become the standard internal display interface for modern computing boards. Legacy LVDS panels require up to 20 separate copper wires to transmit Full HD video, creating heavy cable runs and high EMI risks. In contrast, eDP transmits high-definition video over a single differential lane pair, allowing the entire system to use a thin, flexible micro-coaxial cable. By integrating power, backlighting controls, and AUX channel communication onto one 30-pin or 40-pin connector, Keetronics eDP modules offer cleaner routing, higher reliability, and massive power savings in advanced embedded HMIs.

  • High-density micro-coaxial connectors (0.5mm pitch I-PEX style)
  • Integrated AUX channel carrying DDC, EDID, and backlight control registers
  • Support for up to 30-bit Deep Color representation
  • Complete compatibility with Intel Core, AMD Ryzen, and NVIDIA Jetson SOCs
