    Abstract: A display such as a liquid crystal display may have an array of pixels that is illuminated using backlight illumination from a backlight. The backlight may have a light guide layer that distributes light from light-emitting diodes across the display. The light guide layer may have a planar portion that provides backlight illumination to the array of pixels and may have bent edge portions that curve out of the plane of the planar portion. Light scattering structures may be formed in the planar portion to extract backlight illumination from the light guide layer. A light sensor adjacent to the bent portion may monitor leaked light. The light guide layer may have two bent portions on opposing edges of the light guide layer.

    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: A backlight unit may include a turning film that receives light from a light guide layer. The turning film may have a plurality of elongated protrusions that extend across the turning film. Each protrusion may have a concave surface. The concave surface may be a curved surface that curves inward towards the interior of the turning film. Light from the light guide layer may pass through the turning film and be reflected towards a viewer by the concave surfaces of the protrusions. In a liquid crystal display, the turning film may be interposed between the light guide layer and a lower polarizer. In certain embodiments, the turning film may be the only optical layer interposed between the light guide layer and the lower polarizer. In other embodiments, the turning layer and a diffuser layer may be the only optical layers interposed between the light guide layer and the lower polarizer.

    Abstract: A display polarizer may have a polymer layer such as a polyvinyl alcohol layer coated with a dichroic dye such as iodine. A polymer layer such as a tri-acetyl cellulose layer may be formed on the polyvinyl alcohol layer so that the iodine is interposed between the polyvinyl alcohol layer and the tri-acetyl cellulose layer. To provide protection for the iodine layer, an additional polymer layer such as an additional tri-acetyl cellulose layer and a layer of adhesive may be formed on top of the polymer layer. A functional layer such as an antireflection layer may form an outermost layer in the polarizer. Compensation films may be formed beneath the polyvinyl alcohol layer. Additional display layers such as a lower polarizer layer and interposed layers such as a thin-film transistor layer, liquid crystal layer, and color filter layer may be formed below the compensation films.

    Abstract: An electronic device may be provided with a display. The display may have an active area with an array of display pixels and an inactive border region containing metal lines and other support circuitry. The array of display pixels may be formed from organic light-emitting diode structures in an organic-light-emitting diode layer. The display may also include an encapsulant layer on the organic light-emitting diode layer and a substrate layer. An opaque masking layer may be formed in the inactive border region. The opaque masking layer may overlap structures in the inactive border region such as the support circuitry, thereby blocking the support circuitry from view. The opaque masking layer may be formed a glass layer in the display, in part of a polarizer in a display, under a planarization layer, or between other layers in the display.

    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: 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.
