Abstract: An electronic device may be provided with a display. The display may be overlapped by an antiglare film. The antiglare film may have a rough surface to diffuse incident light, thereby reducing glare. Additionally, the antiglare film may have a smooth portion that forms a transparent window and allows light to pass through undiffused. The electronic device may include a light-based component, such as a camera, that receives undiffused light through the transparent window. By overlapping the light-based component with the transparent window, the light-based component may receive the light in an unimpeded manner, thereby making more accurate measurements of the light. The display may have one or more display layers, such as opaque masking layers or polarizers, with openings that are aligned with the transparent window. The light-based component may receive the light through these openings so that the light is not absorbed or polarized before reaching the component.

Abstract: An array of pixels in a display may be illuminated by a backlight having an array of light-emitting diodes in an array of respective cells. A reflector is used to reflect light from the light-emitting diodes through the array of pixels. Within the cells, the reflector has cross-sectional profiles that help distribute light emitted from the light-emitting diodes toward edges of the cells. A light diffuser layer for the backlight may have a partially reflective layer such as a thin-film interference filter with an angularly dependent transmission. Within each cell, the reflector may have cross-sectional profiles with portions that are parabolic or elliptical.

Abstract: An array of pixels in a display may be illuminated by a backlight having an array of light-emitting diodes in an array of respective light-emitting diode cells. A cavity reflector in each cell may help distribute blue light emitted from the light-emitting diode of that cell toward edges of the cell. Optical films in the backlight may include a photoluminescent layer such as a phosphor layer that converts blue light from the light-emitting diode array into white light and may include a dichroic filter for reflecting white light away from the diode array towards the pixel array. A light diffuser layer for the backlight may have printed white ink pads, recesses filled with a high index of refraction material, protrusions for light scattering, light-scattering particles, thin-film interference filters, partially reflective mirrors, and other structures for diffusing the light from the light-emitting diodes.
