    USB Type C to eDP interface

    ddarmon_2274791

      My system uses a Toshiba TC358860XBG which converts an Embedded Display Port (eDP) video stream into an MIPI DSI stream. I would like to interface a Cypress CCG3 USB Type C controller with the eDP interface of the TC358860.

         

      Is the DisplayPort interface supported by USB Type C compatible with eDP? Or is an extra bridge required to interface DP with eDP? 

         

      Thank you.

          Hi Ddarmon,

           

          Is the DisplayPort interface supported by USB Type C compatible with eDP? Or is an extra bridge required to interface DP with eDP?

          >> This is questions based on DisplayPort SPEC. So that I have to explain the difference between DP and eDP here.

          DisplayPort™

          • External display Interface

          • Needs to interoperate with any external DP Display

          • Many optional features tailored for external display flexibility: HDCP, audio, dual-mode adapters, multi-stream, etc

          Embedded DisplayPort (eDP™)

          • Internal display interface for PC products

          • Uses same GPU video port as external DisplayPort connections

          • Examples where eDP would be utilized: notebooks, netbooks, notepads, all-in-one systems

          • Based on DisplayPort standard with some modifications Protocol and features optimized for internal display use • Only needs to interoperate with dedicated system display

           

          >> As per VESA DisplayPort Alternate Mode on Type-C, we shall be support DisplayPort.

          >> From our solution end, there are shall be no hardware/firmware difference on CCG3 between DP and eDP. But as per VESA DP SEPC, the eDP shall not use it external display Interface.

           

          Best Regards,
