A display device includes an eyeball tracking inductor, a display panel and a processor, where the processor is electrically connected to the eyeball tracking inductor and the display panel separately; the eyeball tracking inductor is configured to identify user eyeball image information; the processor is configured to determine a gaze region and a split view region of a user viewing the display panel, according to the user eyeball image information, control the gaze region to be displayed at a first resolution, and control the split vision region of the display panel to be displayed at a second resolution, where the first resolution is greater than the second resolution.

A system and method is disclosed that allows multiple casting devices to work together to populate a large display screen according to the subject matter disclosed herein. The system includes a receiving device that includes two or more screen-cast receivers and a controller. Each screen-cast receiver receives from a corresponding casting device at least a portion of a frame of original content of the corresponding casting device generated in a native resolution of the corresponding casting device. The controller synchronizes each received portion of the frame of the original content of the corresponding casting device to form a video output signal that comprises a combination of each received portion, in addition to any internally generated content derived by the receiving display. A casting device may be a smartphone, a tablet, or a computing device, such as a laptop computer.

A method for updating information for a graphics pipeline including executing in the first frame period an application on a CPU to generate primitives of a scene for a first video frame. Gaze tracking information is received in a second frame period for an eye of a user. In the second frame period a landing point on an HMD display is predicted at the CPU based at least on the gaze tracking information. A late update of the predicted landing point to a buffer accessible by the GPU is performed in the second frame period. Shader operations are performed in the GPU in the second frame period to generate pixel data based on the primitives and based on the predicted landing point, wherein the pixel data is stored into a frame buffer. The pixel data is scanned out in the third frame period from the frame buffer to the HMD.
