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: A system may have a display that includes a plurality of light sources such as light-emitting diodes. The display may be an exterior display that is routinely operated in daytime conditions where ambient light levels are very high. To increase contrast in an exterior display, the display may include a sunlight blocking element. A static sunlight blocking element may include a louver film with asymmetric light blocking portions. The system may include an ambient light sensor that is configured to determine ambient light levels. Based on the detected ambient light level, control circuitry in the system may adjust one or more adjustable components in the display. The display may include an adjustable diffuser that has at least two states with different haze levels. The display may include an adjustable tint layer that has at least two states with different transmission levels.

Abstract: A display may include a color filter layer, a liquid crystal layer, and a thin-film transistor layer. A camera window may be formed in the display to accommodate a camera. The camera window may be formed by creating a notch in the thin-film transistor layer that extends inwardly from the edge of the thin-film transistor layer. The notch may be formed by scribing the thin-film transistor layer around the notch location and breaking away a portion of the thin-film transistor layer. A camera window may also be formed by grinding a hole in the display. The hole may penetrate partway into the thin-film transistor layer, may penetrate through the transistor layer but not into the color filter layer, or may pass through the thin-film transistor layer and partly into the color filter layer.

Abstract: To enable a display to display different content to different viewers, a display may include a time-sequential directional backlight unit. The backlight unit may emit light in different directions in different configurations. In a first state, the backlight unit emits light at maximum brightness in a first direction. In a second state, the backlight unit emits light at maximum brightness in a second direction that is different than the first direction. The backlight unit may repeatedly and rapidly switch between the different states. The first direction may be towards a first viewer whereas the second direction may be towards a second, different viewer. Therefore, each viewer receives backlight in one of the configurations and does not receive backlight in the other configuration. In synchronization with the backlight unit, the liquid crystal display panel may repeatedly switch between displaying content for the first viewer and displaying content for the second viewer.

Abstract: Embodiments described herein generally take the form of an electronic device including a primary and secondary display; at least the secondary display is force-sensitive and further has its force-sensing circuitry in-plane with the display. The secondary display and force-sensing circuitry may be encapsulated between two glass layers that are bonded to one another by a frit. In some embodiments the force-sensing circuitry is formed from, or constitutes part of, the frit.

Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.

Abstract: A pixel array may be illuminated with backlight illumination from a backlight. The backlight may include a two-dimensional array of light-emitting diodes, with each light-emitting diode being placed in a respective cell. Different light-emitting diodes may have unique brightness magnitudes based on the content of the given display frame. Driver integrated circuits may control one or more associated light-emitting diodes to have a desired brightness level. The driver integrated circuits may be formed in an active area of the backlight. The driver integrated circuits may be arranged in groups that are daisy chained together. A digital signal (that includes information such as addressing information) may be propagated through the group of driver integrated circuits. To manage thermal performance of the backlight, the backlight may include a thermally conductive layer and/or a heat sink structure. To increase the efficiency of the backlight, the backlight may include one or more reflective layers.

Abstract: An electronic device may have a display. Inactive portions of the display such as peripheral portions of the display may be masked using an opaque masking layer. An opening may be provided in the opaque masking layer to allow light to pass. For example, a logo may be viewed through an opening in the opaque masking layer and a camera may receive light through an opening in the opaque masking layer. The display may include upper and lower polarizers, a color filter layer, and a thin-film transistor layer. The opaque masking layer may be formed on the upper polarizer, may be interposed between the upper polarizer and the color filter layer, or may be interposed between the color filter layer and the thin-film transistor layer. The upper polarizer may have unpolarized windows for cameras, logos, or other internal structures.

Abstract: An electronic device may have a housing in which a display is mounted. A gasket may be mounted in a groove between the display and housing. The gasket may contain an embedded stiffener. Corner brackets may be installed in the corners of the housing. The housing may have inner and outer concentric ribs. Recesses in the housing may be configured to receive the corner brackets. The recesses may be formed between the inner and outer concentric ribs. Gap filling structures such as a foam layer may be interposed between a rear housing wall and a display backlight unit. Display color variations may be corrected by using a backlight unit having an array of light-emitting diodes of different colors. An electrostatic discharge protection layer may be grounded to a housing using conductive tape. Black edge coatings and adhesive-based structures may block stray light. Camera window regions may be supported using adhesive.
