Goodbye LVDS, Hello Embedded DisplayPort Standard

The Video Electronics Standards Association (VESA) rolled out version 1.3 of the Embedded DisplayPort Standard (eDP). eDP v1.3 features Panel Self-Refresh (PSR) for saving system power and extending battery life in portable PC systems. The Embedded DisplayPort Standard is a companion standard to the DisplayPort interface designed for embedded display applications, including notebook PCs, tablets, netbooks and all-in-one desktop PCs.

eDP v1.3 Standard Features

  • Panel Self-Refresh (PSR)
  • Saves system power and further extends battery life in portable PC systems
  • Adds clarity on how to use the new 5.4 Gb/s DisplayPort main link data rate [HBR2 (High Bit Rate 2)]
  • Available for purchase from VESA (free for VESA member companies)
  • Portable PC devices utilizing the eDP v1.3 PSR are expected in early 2012

Based on industry market trends, eDP will eventually replace LVDS (Low-Voltage Differential Signaling). By 2013, Intel and AMD will no longer support LVDS in favor of scalable and lower power digital interfaces (such as DisplayPort). Dell, Lenovo, Samsung and LG Display also will phase out legacy technologies in the coming years. Industry analysts believe eDP is the ideal replacement for LVDS. eDP offers a feature-rich replacement that is cost effective and ready for high volume implementation.

The Video Electronics Standards Association (VESA) is an internationally non-profit standards organization, representing a global network of hardware, software, PC, display and component manufacturers committed to developing and promoting the electronics industry.
