Abstract: A display has an array of display pixels formed from display layers such as one or more polarizer layers, a substrate on which an array of display pixel elements such as color filter elements and downconverter elements are formed, a liquid crystal layer, and a thin-film transistor layer that includes display pixel electrodes and display pixel thin-film transistors for driving control signals onto the display pixel electrodes to modulate light passing through the display pixels. A light source such as one or more laser diodes or light-emitting diodes may be used to generate light for the display. The light may be launched into the edge of a polymer layer or other light guide plate structure. A light guide plate may include phase-matched structures such as holographically recorded gratings or photonic lattices that direct the light upwards through the array of display pixels.

Abstract: An electronic device may be provided with a display. The display may include display layers characterized by an active area and backlight structures that provide backlight to the active area. To accommodate components such as a button, an edge portion of a light guide plate in the backlight structures that does not overlap the active area is bent out of the plane of the light guide plate. The bent edge portion of the light guide plate may be formed by molding clear plastic in a die or by bending a flexible sheet of clear polymer. Flared structures may be formed on the flexible sheet of clear polymer to help guide light from light-emitting diodes into the flexible sheet of clear polymer. The flared structures may be formed by applying resin coating layers to the flexible sheet of clear polymer.

Abstract: An electronic device is provided with a display such as a liquid crystal display. The display includes a liquid crystal display module an array of display pixels. A backlight unit is used to provide backlight illumination to the display module. A shutter module having local dimming elements is used to locally control the amount of light that is transmitted through the display. The local dimming elements can be formed from liquid crystal display structures, polymer-dispersed liquid crystal display structures, photovoltaic material, electrowetting display structures, and/or other suitable light controlling elements. Each local dimming element controls the amount of light that is transmitted through an overlapping region of the array of display pixels. The local dimming elements may be arranged in a uniform array having rows and columns or may be shaped and sized differently and located in specific regions of the display.

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: Electronic devices may be provided with display structures such as glass and polymer layers in a liquid crystal display. The glass layers may serve as substrates for components such as a color filter layer and thin-film transistor layer. The polymer layers may include films such as a polarizer film and other optical films. During fabrication of a display, the polymer layers and glass layers may be laminated to one another. Portions of the polymer layers may extend past the edges of the glass layers. Laser cutting techniques may be used to trim away excess portions of the polymer layer that do not overlap underlying portions of the glass layers. Laser cutting may involve application of an adjustable infrared laser beam.

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.
