    Abstract: An electronic device may include a stereoscopic display that is configured to display three-dimensional content for a viewer. The stereoscopic display may include a lenticular lens film with lenticular lenses that extend across the length of the display and may be referred to as a lenticular display. The lenticular display may have convex curvature. The lenticular display may include a color filter layer with color filters and an opaque masking layer. The color filter layer may be interposed between the lenticular lens film and an array of display pixels for the display. The color filter layer may mitigate ghost image artifacts and reflections of ambient light. Microlenses may be included between the lenticular lens film and the array of display pixels to improve the efficiency of the display. The display may include a Fresnel lens layer. The lenticular lens film may include lenticular lenses having different shapes.

    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 generate content that includes a plurality of two-dimensional images, each two-dimensional image corresponding to a respective viewing zone. Pixel mapping circuitry may be used to map the two-dimensional images to the array of pixels in the lenticular display. The array of pixels may have a diagonal layout. An offset map may be used by the pixel mapping circuitry to account for the diagonal layout.

    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. Crosstalk between viewing zones and disparity between images received from different viewing zones may result in disparity-caused shifts in images perceived by viewer of the lenticular display. To mitigate these disparity-caused shifts, compensation circuitry may be included in the display pipeline circuitry. The compensation circuitry may include stored disparity-caused shift calibration information that is used for the compensation. The stored disparity-caused shift calibration information may be a polynomial function that outputs a magnitude of disparity-caused shift for a given pixel location.

    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.
