Abstract: Systems and methods for improving perceived image quality of an electronic display, which includes a display region with a rounded border and a display pixel at a pixel position adjacent the rounded border. A display pipeline communicatively coupled to the electronic display receives first image data that indicates target luminance at the pixel position in a rectangular image frame; determines a gain value associated with the pixel position from a gain map, in which the gain value is inversely proportional to distance between the display pixel and the rounded border; determines second image data that indicates target luminance of the display pixel by processing the first image data based at least in part on the gain value; and outputs the second image data to the electronic display to facilitate displaying a non-rectangular portion of the image frame on the display region.

Abstract: Systems and methods for improving perceived image quality of an electronic display, which includes a co-located sub-pixel that controls luminance of a first color component and an offset sub-pixel that controls luminance of a second color component. A display pipeline communicatively coupled to the electronic display determines image data, which indicates target luminance of the first, the second, and a third color component at an image pixel; determines edge parameters, which indicate whether an edge is expected to be present at the offset sub-pixel, based on a difference metric between a first image pixel block around the offset sub-pixel and a second image pixel block offset from the first image pixel block; and determines offset sub-pixel image data by filtering an image pixel group around the offset sub-pixel based at least in part on the edge parameters, wherein the offset sub-pixel image data indicates target luminance of the offset sub-pixel.
