Abstract
Image data for a current image frame may be compensated for transient response variations due to variations at various positions of the display panel by performing pixel drive compensation. The pixel drive compensation may be performed based at least in part upon a multi-frame history of the display panel. In this way, drive compensation corresponding to multi-frame history of a display panel may be implemented.
Claims20
Drive compensation circuitry, configured to:
- receive a multi-frame history from memory, the multi-frame history based upon first pixel data of a first frame and second pixel data of a second frame subsequent to the first frame;
- determine a drive compensation value based on third pixel data of a third frame and the multi-frame history, wherein the drive compensation value indicates a pixel value modification for a pixel of an electronic display;
- provide an additional multi-frame history based on the drive compensation value to selection circuitry coupled to the memory;
- and
- provide the drive compensation value to a display pipeline associated with the electronic display.

A method, comprising:
- receiving a multi-frame history from memory, the multi-frame history based upon first pixel data of a first previously modified frame and second pixel data of a second previously modified frame subsequent to the first frame;
- and
- determining a drive compensation value for a pixel value of a pixel of an electronic display based on third pixel data of a third frame and the multi-frame history;
- and
- providing the drive compensation value to a display pipeline associated with the electronic display.
2 more elements
An electronic device comprising:
- a display panel;
- a memory;
- and
- a display pipeline coupled between the memory and the display panel, wherein the display pipeline comprises:
- drive compensation circuitry, configured to:
- receive, at a first time, a multi-frame history from the memory, the multi-frame history based upon first pixel data of a first frame and second pixel data of a second frame subsequent to the first frame, the first pixel data and the second pixel data having been modified before the first time;
- determine a drive compensation value for a pixel value of a pixel of the display panel based at least in part on third pixel data of a third frame and the multi-frame history;
- and
- provide the drive compensation value to the display pipeline.
