  • Publication number: 20220091418
    Abstract: A method of leakage-compensated global illumination comprises obtaining position data for at least one of a head or an eye of a user of a display system by an application processor, rendering image data for an image frame by the application processor based on the position data, modifying the image data to compensate for leakage associated with a global illumination by a display of the display system, and sending the image data to a display driver circuit of the display system for displaying the image frame on the display through the global illumination.

  • Patent number: 11209656
    Abstract: A method including determining a maximum luminance location of a display based on a field of view of an eye of a user of the display, and driving a plurality of light sources in the display based on locations of the plurality of light sources with respect to the maximum luminance location of the display. The plurality of light sources is controlled to have different luminance levels in different display zones corresponding to different zones on the retina of the eye of the user. In some examples, the display zones of the display system that have higher luminance levels can be dynamically changed based on the field of view or the gaze direction of the eye of the user.

  • Patent number: 11158690
    Abstract: A method of manufacturing a display system includes forming a display element having a display active area over a silicon backplane, forming a display driver integrated circuit (DDIC), and bonding the display element to the display driver integrated circuit (DDIC). The display active area may include a light emitting diode such as an organic light emitting diode (OLED). Separately forming the display and the display circuitry may simplify formation of the OLED and allow for a higher density control interface between the display and the DDIC.

  • Patent number: 11127325
    Abstract: Technologies for performing a simplified pixel shifting scheme on a display (e.g., an organic light emitting diode (OLED) display) are disclosed herein. An electronic device presents, on the display, a virtual display having an active area and a margin area surrounding the active area. The active area is to display content (e.g., image data, video data, etc.), and an amount of pixels in the virtual display is greater than an amount of pixels in the active area. The electronic device is also to shift the pixels of the active area within the virtual display according to a pixel shifting technique and update a touch coordinate offset for the touch screen interface based on the shift.

  • Publication number: 20210201446
    Abstract: Examples disclosed herein obtain first image data and the second image data for a foveated image frame to be displayed on a display, the first image data to have a first resolution and the second image data to have a second resolution lower than the first resolution. Disclosed examples also up-sample the second image data based on first metadata to generate up-sampled second image data, the up-sampled second image data to have the first resolution, and combine the first image data and the up-sampled second image data based on second metadata. Disclosed examples further perform, based on third metadata, a combination of at least two different filter operations on an overlap region including a portion of the first image data and a portion of the up-sampled second image data to generate the foveated image frame, the third metadata to specify a width in pixels of the overlap region.

  • Patent number: 11039041
    Abstract: Technology for a display device is described. The display device can include one or more display screens operable to show at least two display panels. The display device can include a controller. The controller can send a request for frame data from each of the at least two display panels to a source device. The controller can receive, from the source device, a same frame indication for each of the at least two display panels. The controller can provide frame data received from the source device based on the same frame indication to the at least two display panels. The same frame indication can cause the at least two display panels to synchronously display frame data received from the source device.

  • Patent number: 10712569
    Abstract: Technologies for virtual reality display include a computing device coupled to a head-mounted display device. The head-mounted display includes a display panel, a pixel emission controller, and a pancake lens assembly. The display panel includes a display surface that emits light as multiple pixels. The pancake lens assembly includes folded optics to direct light to an eye box. The pixel emission controller applies an emission profile to each pixel of the light as a function of the position on the display surface of the corresponding pixel. The emission profile is determined based on an optical coupling between the position on the display surface through the pancake lens assembly to the eye box. The beam width of each pixel may decrease and the beam angle relative to an optical axis may increase as distance from the optical axis increases. Other embodiments are described and claimed.
