    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 array of pixels in a display may be illuminated by a backlight having an array of light-emitting diodes in an array of respective cells. A reflector is used to reflect light from the light-emitting diodes through the array of pixels. Within the cells, the reflector has cross-sectional profiles that help distribute light emitted from the light-emitting diodes toward edges of the cells. A light diffuser layer for the backlight may have a partially reflective layer such as a thin-film interference filter with an angularly dependent transmission. Within each cell, the reflector may have cross-sectional profiles with portions that are parabolic or elliptical.

    Abstract: An electronic device may include a display. The display includes display driver circuitry for driving data lines routed across the display. The electronic device may have a recessed device housing region, where at least some of the data lines are routed around the recessed region. The data lines being routed around the recessed region may be formed in at least two different metal routing layers. The electronic device may further include additional display driver circuitry for driving data lines from another peripheral housing edge to obviate the need to route around the recessed region. The data lines from the two display driver circuitries can be disconnected at random locations or can be interlaced to achieve spatial interleaving. The display driver circuitry may include demultiplexing circuitry having smaller switches coupled in parallel with larger demultiplexer routing switches to reduce voltage kick and charge injection.

    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 louver film may have a plurality of transparent portions separated by opaque walls. The opaque walls may control the emission angle of light from the display, reducing crosstalk. The louver film may be interposed between the lenticular lens film and the display panel.

    Abstract: A display may have a backlight unit that provides backlight illumination. The backlight unit may include a light guide that distributes light through the display. The light guide may include opposing first and second edges. A first light source such as a first row of light-emitting diodes may emit light into the first edge and a second light source such as a second row of light-emitting diodes may emit light into the second edge. In a normal viewing mode, both light sources are active and backlight illumination is provided over a normal range of angles. In a restricted angle-of-view mode, only one light source is active and backlight is emitted in a more concentrated fashion over a restricted range of angles. In a high luminance restricted angle-of-view mode, the active light source is driven at an elevated level.

    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.
