Embedded DisplayPort: Increased flexibility and power savings render greater display efficiency
While mobile device display performance continues to increase, system chip processes geometries continue to shrink, resulting in a greater proportion of system power consumed by the display and its high-speed interface. The new Embedded Display Port (eDP) v1.4 standard offers several new features that maximize system power efficiency, further consolidate the display interface, and address a wide range of system profiles to satisfy the growing demand for power optimization in the embedded display system.
The Video Electronics Standards Association (VESA) first released the Embedded Display Port (eDP) standard in 2009 as an extension of the DisplayPort standard for use with embedded displays. VESA developed eDP to replace the aging Low-Voltage Differential Signaling (LVDS) standard, and today eDP is used widely in notebook computers and all-in-one systems. The primary benefits of eDP over LVDS include the reduction of signal wires due to its higher data rate, compatibility with submicron chip processes, decreased interference with wireless services, and its ability to accommodate new features.
