A virtual reality (VR) display device and a display method are provided, so as to improve the problems that an existing VR display device has higher power consumption and waste of resources. The display method for the VR display device includes: in response to a first operation of a user, initiating a smartview mode (S101); controlling display in a first display region of a screen of the VR display device to be at first definition; controlling display in a second display region, other than the first display region, of the screen of the VR display device to be at second definition (S102); and supplementing and displaying black for part of pixels in the second display region (S103); the first display region is a region watched by human eyes; and the first definition is greater than the second definition.

Embodiments of the present application provide various image display control methods and apparatus, and various display devices. One of the image display control methods comprises: acquiring target pixel density distribution information displayed by an image; adjusting display pixel density distribution of a display according to the target pixel density distribution information; and displaying the image according to the adjusted display. The technical solutions provided in the embodiments of the present application can fully use overall display pixels of a display to differently present display definition of different regions in an image and improve actual usage of the display pixels, which can better meet diversified application needs of a user.

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.

Systems, methods and apparatuses may provide for technology to reduce rendering overhead associated with light field displays. The technology may conduct data formatting, re-projection, foveation, tile binning and/or image warping operations with respect to a plurality of display planes in a light field display.

Complementary near-field and far-field light field displays (LFDs) are provided. A distributed LFD system is disclosed in which the light field is cooperatively displayed by a direct view LFD and a near-eye LFD. The two display components of the system work together synchronously to display a high-fidelity 3D experience to one or multiple viewers.
