摘要:
An electronic device may have a liquid crystal display with backlight structures. The backlight structures may produce backlight that passes through an array of display pixels. The display pixels may include electrode structures and thin-film transistor structures for controlling electric fields in a layer of liquid crystal material. The liquid crystal material may be formed between an outer display layer and an inner display layer. The inner display layer may be interposed between the backlight structures and the liquid crystal material. Thin-film transistor structures, electrodes, and conductive interconnection lines may be deposited in a layer on the inner surface of the outer display layer. A layer of color filter elements may be used to provide the display with color pixels. The color filter elements may be formed on top of the thin-film transistor layer or on a separate color filter array substrate such as the inner display layer.

A display may include a backlight structure. The backlight structure may include a light guide plate. Holes in the light guide plate may be configured to receive corresponding light-emitting diodes. The holes may separate an edge portion of the light guide plate from a main central portion of the light guide plate. Adhesive may be attached to the lower surface of the edge portion. The adhesive may be attached to a device housing or may be attached to a flex circuit that is attached to the housing with additional adhesive. The light-emitting diodes may be mounted within packages in pairs. The packages may be mounted on the flex circuit. Traces on part of the flex circuit may be covered by part of the light guide plate without any intervening adhesive. A reflective structure may be interposed between the traces and parts of the main portion of the light guide plate.

An electronic device may have a display such as a liquid crystal display. The display may have an array of display pixels. The array of display pixels may display images for a user in an active area of the display. An inactive area of the display may surround the active area. An opaque masking layer may be provided in the inactive area to block internal components in the electronic device from view. An optical component such as a light-based proximity sensor, ambient light sensor, image sensor, or light-emitting status indicator may be aligned with an opening in the opaque masking layer. A liquid crystal shutter may be provided in the display. The liquid crystal shutter may be controlled by control circuitry in the electronic device. The liquid crystal shutter may be aligned with the opening in the opaque masking layer in the inactive area and with the optical component.

The color filter elements may be interposed between the thin-film transistor layer and the backlight structures or the thin-film transistor layer may be interposed between the color filter elements and the backlight structures. The backlight structures may be formed from optical fiber, a two-dimensional array of light-emitting diodes, a light guide plate that includes a rectangular recess for receiving optical films, or light guide plate structures that include internal light scattering structures. A light guide plate may be provided with alignment features that mate with alignment features on optical films.

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.
