Abstract: A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The dynamic range of the display may be enhanced by using the second stage to perform local dimming operations. The pixel pitch of the second stage may be greater than the pixel pitch of the first stage to ease alignment tolerances and reduce image processing complexity. The color stage and monochromatic stages may share a polarizer. A color filter in the color stage may have an array of red, green, and blue elements or an array of white, red, green, and blue elements. The color stage may be a fringe field display and the monochrome stage may be an in-plane switching display or a twisted nematic stage.

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 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: An electronic device may include a display having an array of display pixels. Each display pixel may include a red subpixel, a green subpixel, a blue subpixel, and a white subpixel. The display may be controlled using display control circuitry. The display control circuitry may convert frames of display data from a red-green-blue (RGB) color space to a red-green-blue-white (RGBW) color space. The display control circuitry may supply data signals corresponding to a frame of display data in the RGBW color space to the array of display pixels. A frame of display data may be converted from the RGB color space to the RGBW color space based on an amount of color saturation in the frame of display data, based on information identifying what code is running on control circuitry in the electronic device, and/or based on ambient lighting condition information.

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.
