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.
