Abstract: Electronic devices may be provided with backlight structures that provide backlight illumination for a display. The backlight structures include a light source such as an array of light-emitting diodes that launches light into an edge of a light guide plate. The light guide plate distributes the light laterally across display layers in the display. One or more optical films such as brightness enhancement films and diffuser layers are interposed between the display layers and the light guide plate. The light guide plate includes light guide plate alignment features that mate with corresponding optical film alignment features in the optical films. The light guide plate alignment features may be protrusions that extend into openings such as notches or holes in the optical films. The light guide plate may have a protruding portion that extends around a periphery of the light guide plate and surrounds a perimeter of the optical films.

Abstract: An electronic device such as a laptop computer or other device may have a housing. A display may be coupled to the housing. The display may have a pixel array configured to display an image. Backlight illumination for the pixel array may be provide by a backlight unit. The backlight unit may have a light guide layer. A light source may provide light to an edge of the light guide layer. The light guide layer may scatter the light outwardly to serve as the backlight illumination for the pixel array. The backlight unit may have optical films interposed between the light guide layer and the pixel array. The optical films may include flexible polymer layers such as diffuser layers and prism films. The optical films may each have a bent alignment portion that bends back on itself while wrapping around an edge of the light guide layer.

Abstract: A display (14) may include a color filter layer (56), a liquid crystal layer (52), and a thin-film transistor layer (58). A camera window opening (84) may be formed in the display (14) to accommodate a camera (86). The camera window opening (84) may be formed by creating a notch (84) in the thin-film transistor layer (58) that extends inwardly from the edge of the thin-film transistor layer (58). The notch (84) may be formed by scribing the thin-film transistor layer (58) around the notch location and breaking away a portion (58") of the thin-film transistor layer (58). A camera window opening (84) may also be formed by grinding a hole (84) in the display (14). The hole (84) may penetrate partway into the thin-film transistor layer (58), may penetrate through the thin-film transistor layer (58) but not into the color filter layer (56), or may pass through the thin-film transistor layer (58) and partly into the color filter layer (56).
