VESA ® Issues Updated Embedded DisplayPort® Standard

-Version 1.3 created to save system power and further extend device battery life

NEWARK, Calif.–The Video Electronics Standards Association (VESA) has announced a new version of the Embedded DisplayPort Standard (eDP™). eDP 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 includes a new Panel Self-Refresh (PSR) feature that was developed to save system power and further extend battery life in portable PC systems.

Industry market trends indicate that eDP is slated to replace LVDS (Low-Voltage Differential Signaling), the previous standard for LCD panel inputs. In December 2010, Intel and AMD announced that by 2013, the two companies will no longer support LVDS in favor of scalable and lower power digital interfaces, such as DisplayPort. Leading PC manufacturers Dell, Lenovo, Samsung and LG Display announced similar plans to phase out legacy technologies in the coming years.

With eDP now even more capable of saving total device power and battery life, industry analysts believe it is the ideal replacement for LVDS. “As OEMs prepare to retire legacy technologies, such as LVDS, eDP offers a feature-rich replacement that is cost effective and ready for high volume implementation,” says Brian O’Rourke, principal analyst, In-Stat. “This, combined with the growing demand for high performance mobile devices, suggests eDP will continue to gain traction among PC OEMs.”

The eDP v1.3 Standard adds clarity on how to use the new 5.4, Gb/s DisplayPort main link data rate, also known as HBR2 (High Bit Rate 2). eDP v1.3 is now available for purchase from VESA and is provided free of charge to VESA member companies. Portable PC devices utilizing the new eDP v1.3 PSR feature are expected to become available for purchase as early as 2012.
