Abstract: Electronic devices may be provided with displays that have polarizers. A polarizer may have a polymer layer that has a portion covered with a dichroic dye to form a polarized region and a portion that is free of dichroic dye to form an unpolarized region. The unpolarized region may be formed by masking the polymer layer during a dye coating process. Masks may be formed from polymers. The shape of the mask may define the shape of the unpolarized region. The mask may be left in place within the polarizer or may be removed from the polarizer during fabrication. Unpolarized regions may also be formed by light bleaching, chemical bleaching, and material removal techniques. Bleached areas may be chemically stabilized. A moisture barrier layer may be incorporated into the polarizer to help prevent the unpolarized region from reverting to a polarized state.

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: 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: 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: Electronic devices may include displays. A display may include display layers having an array of display pixels and a backlight unit that provides backlight illumination to the display pixels. The backlight unit may include a light guide plate that distributes light across the display layers and a stack of optical films that may be used to enhance backlight performance. The optical films may be interposed between the light guide plate and the display layers. The light guide plate may be provided with one or more rounded edges formed from curved surfaces and/or one or more beveled edges formed from chamfered surfaces. Providing the light guide plate with rounded or beveled edges may minimize abrasive contact between the light guide plate and the adjacent optical films. An injection molding tool may be used to mold a light guide plate with rounded or beveled edges.
