Abstract: A display system includes a display panel having an input to receive pixel data, the pixel data comprising a plurality of pixel values, an array of pixels partitioned into a foveal region and at least one peripheral region, and an array controller to group pixels in the at least one peripheral region into subsets of at least two pixels and to control each subset using a corresponding single pixel value from the plurality of pixel values. The display system further may include a rendering system to foveally render a display image based on the locations of the foveal region and the at least one peripheral regions, wherein for each row of the display image having pixels within at least one of the peripheral region, a number of pixel values represented in the pixel data for the row is less than a number of pixels in the row.

Abstract: A foveated display system includes a rendering device including at least one graphics processing unit (GPU) to render a foveal region and a peripheral region of a first image, wherein the foveal region has a higher resolution than the peripheral region. The system further includes a display device coupled to the rendering device via at least one physical layer. The display device includes a pixel array and a display controller coupled to the pixel array. The display controller includes a scaling component to upscale the first peripheral region to generate a scaled first peripheral region and a blending component to blend the foveal region with the scaled first peripheral region to generate a second image.
