Abstract: A display device, such as a head mounted device (HMD), displays a virtual scene. The display device includes a motion tracker for detecting rotation of the display device. The display device also includes a processor that is configured to selectively maintain or modify a position of an array of rendered pixels relative to the virtual scene in response to the detected motion. The processor is also configured to upsample the rendered pixels to generate values of display pixels for presentation by the display device. The processor is further configured to translate the values of the display pixels in a rendering plane of the display device based on the detected motion. The translated values of the display pixels can then be presented on a display of the display device.

Abstract: A display device includes a pixel array and a display controller. The pixel array has a non-red-green-blue (non-RGB) pixel format that includes at least first, second, and third color components, and wherein sub-pixels of the first color component are present at a first resolution and sub-pixels of each of the second and third color components are present at a second resolution lower than the first resolution. The display controller is configured to receive a first image in a an RGB pixel format in which sub-pixels of the first color component, sub-pixels of the second color component, and sub-pixels of the third color component each are present in the first image at the second resolution. The display controller further is configured to scale sub-pixels of the first color component in the first image from the second resolution to the first resolution to generate a second image having the non-RGB format.

Abstract: A display system includes a display device and a graphics processing unit (GPU) coupled via at least one physical layer. The display device includes a pixel array having a non-red-green-blue (non-RGB) pixel format. The GPU is configured to render an image in the non-RGB pixel format and provide the rendered image for transmission to the pixel array via the at least one physical layer.

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.
