Higher performance at lower power is the most critical requirement of SoC designs, specifically those targeted towards mobile and consumer electronics applications. VESA (Video Electronics Standards Association), the technical standards organization for computer display standards, came up with a new power saving feature called PSR (Panel Self Refresh) in eDP 1.3. It is also available as an optional feature in DisplayPort. PSR helps to extend battery life in mobile phones, notebooks, and tablets, and is quickly being adopted in high-end designs.

DisplayPort (DP) is a display interface used to connect a video source to display devices such as monitors and projectors. It provides the fastest refresh rate, high resolution with deep color modes, and increased bandwidth with support for all 3D video and audio formats.
