Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user's environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.

Abstract: An electronic device may have a display and a gaze tracking system. The electronic device may display images on the display that have a higher resolution in a portion of the display that overlaps a gaze location than other portions of the display. Timing controller circuitry and column driver circuitry may include interpolation and filter circuitry. The interpolation and filter circuitry may be used to perform nearest neighbor interpolation and two-dimensional spatial filtering on low resolution image data. Display driver circuitry may be configured to load higher resolution data into selected portions of a display. The display driver circuitry may include low and high resolution image data buffers and configurable row driver circuitry. Block enable transistors may be included in a display to allow selected blocks of pixels to be loaded with high resolution image data.

Abstract: An electronic device uses a leader synchronize signal generator to synchronize clock signal generators used by multiple components in the electronic device to a common time-base. A processor core complex of the electronic device sends per-frame configuration to a timing controller for frames to be displayed on an electronic display before a corresponding frame begins.

Abstract: Systems and methods may reduce or eliminate image artifacts due to a defective pixel of an electronic display. An electronic display may include pixels that respectively include a self-emissive element, pixel drive circuitry that supplies a pixel drive current to drive the self-emissive element, and signal routing circuitry that reduces or eliminates a visual artifact due to a defective pixel among the pixels. The signal routing circuitry may do this by turning off the self-emissive element, supplying image data from the pixel drive circuitry to a first adjacent pixel, or receiving image data from other pixel drive circuitry from the first adjacent pixel or a second adjacent pixel.

Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The display may have a number of independently controllable viewing zones. Each viewing zone displays a respective two-dimensional image. Each eye of the viewer may receive a different one of the two-dimensional images, resulting in a perceived three-dimensional image. The electronic device may include display pipeline circuitry that generates and processes content to be displayed on the lenticular display. Content generating circuitry may initially generate content that includes a plurality of two-dimensional images, each two-dimensional image corresponding to a respective viewing zone. The two-dimensional images may be processed by per-view processing circuitry. Pixel mapping circuitry may be used to map the two-dimensional images to the array of pixels in the lenticular display. After pixel mapping, additional panel-level processing may be performed.

Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. A plurality of lenticular lenses may extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have a number of independently controllable viewing zones. The viewer may be particularly susceptible to artifacts caused by crosstalk at the edge viewing zones within the primary field of view of the display. Certain types of content may also be more vulnerable to crosstalk than other types of content. Therefore, to mitigate crosstalk artifacts, the pixel value for each pixel may be adjusted based on the viewing zone of the respective pixel and content information (such as texture information or brightness information) associated with the respective pixel.

Abstract: A compensation system includes a processor configured to determine compensated data for display on a sub-pixel of the display device. The processor may receive image data configured to be displayed on the sub-pixel, convert the gray level data to first voltage data; fetch, from a memory, compressed 1×1 sub-pixel uniformity compensation data for the sub-pixel, and decompress the compressed 1×1 sub-pixel uniformity compensation data via a decompressor. The decompressed data comprises the 1×1 sub-pixel uniformity compensation data for the sub-pixel. The processor may also determine a voltage compensation offset value associated with the sub-pixel based on the second voltage data, generate compensated voltage data based in part on the voltage compensation offset value and the first voltage data, convert the compensated voltage data to compensated gray level data; and transmit the compensated gray level data to pixel driving circuitry associated with the sub-pixel.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To prevent a visible border between the reduced resolution areas of the display and full resolution areas of the display, uniformity compensation circuitry may be used to compensate pixel data. The uniformity compensation circuitry may output compensated pixel data for the display using one or more compensation maps that include compensation factors associated with pixel locations. The uniformity compensation circuitry may also use region-specific gamma look-up tables to apply different gamma curves to pixels in different regions of the display. The uniformity compensation circuitry may also be used to form a transition region between different regions of the display.
