Abstract: A lenticular display may be formed with convex curvature. The lenticular display may have a lenticular lens film with lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display. To enable more curvature in the display while ensuring satisfactory stereoscopic display performance, the display may have stereoscopic zones and non-stereoscopic zones. A central stereoscopic zone may be interposed between first and second non-stereoscopic zones. The non-stereoscopic zones may have more curvature than the stereoscopic zone. To prevent crosstalk within the lenticular display, a louver film may be incorporated into the display. The pixel array may have a diagonal layout and may be covered by vertically oriented lenticular lenses.

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 lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. To mitigate jaggedness in a curved edge of the active area, control circuitry may modify input pixel data for the display using dimming factors. Each brightness value of the pixel data may be multiplied by a corresponding dimming factor such that the curved edge has a smooth appearance. Each physical pixel in the display may have an associated perceived pixel that is based on an appearance of that physical pixel through the lenticular lens film. The perceived pixel may have a different footprint than its corresponding physical pixel. The dimming factors for boundary smoothing in the curved edges may be based on the perceived pixels.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a locally modified region that overlaps the optical sensor. The locally modified region of the display may have a modification relative to a normal region of the display that does not overlap the optical sensor. The modification may mitigate diffractive artifacts that would otherwise impact the optical sensor that senses light passing through the display. To mitigate diffraction artifacts, the locally modified region of the display may use spatial randomization (e.g., spatial randomization of signal paths and/or spatial randomization of via locations), opaque structures may be formed with circular footprints, a black masking layer may be formed with circular openings, apodization may be used, and/or a phase randomization film may be included.

Abstract: An electronic device uses a multidimensional (e.g., 3D) scaler to process multiple-viewing-angle (e.g., 3D-aware) images by resampling each view image and processing image data of each view image according to a view map to change resolution or improve perceived image quality. After being processed, each view image of the multiple-viewing-angle image is used to rebuild a final processed multiple-viewing-angle (e.g., 3D-aware image) with all views for displaying on the electronic device.

Abstract: Electronic devices, displays, and methods are provided for performing pixel grouping to enable efficient display operation at higher frame rates and lower image resolutions without sacrificing significant image quality. An electronic display may include a number of rows of display pixels and driving circuitry. The driving circuitry may receive a frame of image data and drive a set of adjacent groups of rows of equal number using the frame of image data. Adjacent groups of rows may respectively include two or more adjacent rows.

Abstract: In an embodiment, an electronic device includes a display and an eye tracker. The display includes one or more foveated areas. In the embodiment, the eye tracker is configured to collect eye tracking data regarding a gaze of one or more eyes of a user on the display. The electronic device also includes processing circuitry operatively coupled to the display. In the embodiment, the processing circuitry is configured to receive an indication of a motion associated with the gaze from the eye tracker. The processing circuitry is also configured to determine a previous location associated with the gaze during a previous frame and a target position associated with the gaze during a target frame. In the embodiment, the processing circuitry is configured to expand one or more foveated areas of the display adjacent a previous position of the gaze of the user.

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 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. A eye and/or head tracking system may use a camera to capture images of a viewer of the display. Control circuitry in the electronic device may use the captured images from the eye and/or head tracking system to determine which viewing zones are occupied by the viewer's eyes. The control circuitry may disable or dim viewing zones that are not occupied by the viewer's eyes in order to conserve power. An unoccupied viewing zone and an adjacent, occupied viewing zone may display the same image to increase sharpness in the display.

Abstract: An electronic device may include a display having an array of pixels and a backlight that provides backlight illumination for the array of pixels. The backlight may be a direct-lit backlight with a two-dimensional array of light-emitting diodes operable in a local dimming scheme. The electronic device may include control circuitry that provides pixel signals to the array of pixels and backlight signals to the backlight. The control circuitry may adjust the pixel signals and the backlight signals to compensate for brightness and color non-uniformity in the backlight. To compensate for image-dependent backlight non-uniformity, the control circuitry may simulate artificial backlight data based on the target image to be displayed and stored point spread information. To compensate for white-point-dependent backlight non-uniformity, the control circuitry may use measured actual backlight data that describes color variations across the backlight for a given target white point.
