Abstract: An electronic device may have a display. Inactive portions of the display may be masked using an opaque masking layer. An opening may be provided in the masking layer. A camera may receive light through the 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 upper polarizer may have an unpolarized window aligned with the opening in the opaque masking layer for the camera, a logo, or another internal structure. The unpolarized window may be formed from openings in polarizer layers such as a polyvinyl alcohol layer and optical retarder layers. The openings may pass through all or less than all of the polarizer layers. The openings may be filled with transparent filler material. The polarizer may include a try-acetyl cellulose layer that continuously covers the opening in other polarizer layers.

Abstract: An electronic device may be provided with a display mounted in a housing. The display may include a liquid crystal display module and a reflective polarizer having an in-plane optical axis. The display may also include a backlight unit that includes a light source, a light guide element, and a reflector film coupled to a backside of the light guide element. The display may also include a light retardation layer such as a quarter wave film. The quarter wave film may be arranged between the reflective polarizer and the reflector film of the backlight unit. During operation of the display, partially polarized light that is output from a front side of the light guide element may have a first component parallel to the in-plane optical axis and a second component perpendicular to the in-plane optical axis of the reflective polarizer. The second component may be reflected from the reflective polarizer.

Abstract: A display may receive image data to be displayed for a user of an electronic device. Display driver circuitry in the display may include a timing controller that receives the image data. The timing controller can analyze frames of the image data to determine average luminance values for the frames. The display may include an array of organic light-emitting diode display pixels. Each display pixel may include a light-emitting diode. A transistor in each display pixel may be coupled in series with the light-emitting diode between positive and ground power supply terminals. The timing controller can limit peak luminance in the image data that is displayed on the array of display pixels as a function of average luminance. The timing controller can also direct power regulator circuitry to adjust a power supply voltage applied to the positive power supply terminal based on the average luminance.

Abstract: A display may have a layer of liquid crystal material between a color filter layer and a thin-film transistor layer. Column spacer structures may be formed between the color filter layer and the thin-film transistor layer to maintain a desired separation between the color filter and thin-film transistor layers. The column spacer structures may be formed from polymer structures such as photoresist pillars and may include metal pads. The metal pads may be formed on the upper surface of the thin-film transistor layer or the lower surface of the color filter layer. The photoresist pillars may be formed on a surface in the display such as the lower surface of the color filter layer. Column spacer structures may include main spacer structures, subspacer structures, and intermediate thickness spacer structures to enhance pooling mura and light leakage performance.

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.
