    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: Display backlight structures may provide backlight illumination that passes through display layers in the display. Light-emitting diodes may emit blue light into an edge of a light guide plate. Optical films may overlap the light guide plate. The optical films may include a quantum dot enhancement film. A peripheral strip of yellow reflector or other light control structures may be incorporated into the backlight structures to reduce blue edge effects. The light control structures may have features with a spatially varying density, may be formed from quantum dot enhancement film, or may be formed form other structures. The light control structures may be formed on the surfaces of the optical films, on a reflective layer under the light guide plate, or on a surface of a mold frame or other structure that lies in a plane parallel to the plane of the light guide plate.

    Abstract: A display may have an array of pixels that display images for a user. The backlight unit may have a light-guide layer. An array of light-emitting diodes may emit light into an edge of the light-guide layer. The light guide layer may overlap a backlight reflector. The backlight reflector may include a backlight reflector panel formed from a stack of dielectric layers on a rectangular substrate. The backlight reflector may also include a strip of backlight reflector tape having an edge that is overlapped by an edge portion of the backlight reflector panel. Color compensating features such as printed colored ink patterns may be formed on the backlight reflector to adjust the color of backlight illumination in portions of the backlight unit adjacent to the light-emitting diodes.
