Abstract: In one embodiment, a display system includes circuitry to, after an exit from a self-refresh state, obtain first frame data with a first refresh rate and second frame data with a second refresh rate different than the first refresh rate, and based on the second refresh rate being greater than the first refresh rate, determine an amount of drift between timing controller circuitry of a graphics controller and timing controller circuitry of a display panel, and based on the amount of drift being above a threshold value, cause the first frame data to not be displayed and cause the second frame data to be displayed at the first refresh rate.

Abstract: Techniques for low-power self-refreshing of a display are disclosed. In the illustrative embodiment, a display receives frames as a base refresh rate, such as from a graphics processor. The graphics processor may determine that the last frame can be displayed for one or more additional frames and place the link to the display in a sleep state. The display can then refresh the last frame on the display. In order to save power, the display can refresh the last frame on the display at a reduced refresh rate, such as at the minimum refresh rate of the display.

Abstract: In one embodiment, a display panel may have multiple regions that are controlled by independent driver circuitries to allow for independent refreshing of different regions. Circuitry, e.g., in a graphics source or in the display, can determine, based on a partial frame update, which panel regions to refresh and refresh those regions, e.g., while not refreshing other regions of the panel.

Abstract: Various embodiments herein provide apparatuses, systems, and methods associated with a region-based power saving scheme for a display, such as an organic light-emitting diode (OLED) display. In embodiments, pixels of an image may be allocated to two or more subsets including a first subset that corresponds to a region of interest (ROI). The two or more subsets may further include a second subset that includes some or all of the pixels that are outside of the ROI. A more aggressive power saving scheme may be applied to the second subset compared with the first subset (which may or may not undergo a power saving scheme). In some embodiments, a saturation level of the pixels of the second subset may be increased in addition to the dimming. Other embodiments may be described and claimed.
