The DisplayPort is designed for internal and external system solution for high bandwidth audio and video data transfer in the notebook and PC market. The standards, defined by Video Electronics Standards Association (VESA), cover provisions for high definition digital audio-video and graphics streaming via the interface through the same cable. This reduces cost and provides ease of use through the plug-and-play feature making it user- friendly for consumer. It also provides performance scalability for future developments of high quality displays, high color depths and high refresh rates display.


    In accordance to requirements outlined by VESA, has developed the external DisplayPort* Interconnect System solution. It consist of 20-circuit, 0.50mm pitch SMT, external receptacles designed with a polarized D-shape mating interface and metal shield for full EMI/RFI protection. In addition, the connectors are designed with four solder pins for added mechanical stability and robustness, as well as a snap-in plastic peg for positive polarization during connector mounting. The receptacle is to be mounted on the device side and the plug, which is overmolded at both ends of the cable assemblies, on the display device. The cable assemblies come in both latching and non- latching versions with cable length of 2m and 15m. Examples of source applications are desktop PC, set-top box, DVD player or game console, and display applications are the likes of TV monitors or projection display.

DisplayPort. It is as follows:


  • Unify external and internal display interfaces
  • Provide scalable performance in terms of resolution, color depth, and refresh rate over fewer wires to support emerging display needs
  • Provide a future foundation for new display usages
  • Provide a small, user-friendly external connector
  • Accelerate deployment of protected digital outputs on PCs to broadly support authorized viewing of protected content
  • Enable a digital display connection as a viable alternative to VGA.
