Abstract: An electronic device may be provided with a display having a backlight with light sources of different colors. The electronic device may include a color ambient light sensor that measures the color of ambient light and control circuitry that adjusts the color of light emitted from the backlight based on the color of ambient light. The light sources may include at least first and second light-emitting diodes that emit light having different color temperatures. The control circuitry may adjust the intensity of light emitted from the first light-emitting diode relative to the intensity of light emitted from the second light-emitting diode to produce a backlight color that more closely matches the color of ambient light. The first and second light-emitting diodes may include an ultraviolet light-emitting diode die and a blue light-emitting diode die that are mounted in a common semiconductor package.

Abstract: A display may store extended display identification data for communicating the capabilities of the display to a source device such as a graphics processing unit. The extended display identification data may include a red primary color value, a green primary color value, and a blue primary color value. The primary color values in the extended display identification data may be determined during manufacturing. For example, a light sensor may measure the native primary colors of the display, and calibration computing equipment may determine if the native primary colors of the display are within a target color gamut. If the native primary colors of the display are outside of the target color gamut by an amount larger than a threshold, the primary color values in the extended display identification data may be adjusted to account for the color variation.

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.

Abstract: A display may have a backlight with a row of light-emitting diodes that emit light into an edge surface of a light guide layer. The light guide layer may have opposing planar surfaces. Light-scattering structures such as light-scattering holes that extend between the planar surfaces may be used to scatter rays of light by refraction and/or diffraction and can thereby homogenize light from the light-emitting diodes. The homogenized light may then be extracted from the light guide layer and may serve as backlight illumination for an array of pixels such as an array of liquid crystal display pixels. Light-scattering structures such as grooves, pits, bumps, and other structures for scattering light from the light-emitting diodes may be formed on the edge surface of the light guide layer to enhance light mixing.

Abstract: An electronic device may have a display. Inactive portions of the display may be masked using an opaque masking layer. An opening may be provided in the masking layer. A camera may receive light through the 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 upper polarizer may have an unpolarized window aligned with the opening in the opaque masking layer for the camera, a logo, or another internal structure. The unpolarized window may be formed from openings in polarizer layers such as a polyvinyl alcohol layer and optical retarder layers. The openings may pass through all or less than all of the polarizer layers. The openings may be filled with transparent filler material. The polarizer may include a try-acetyl cellulose layer that continuously covers the opening in other polarizer layers.

Abstract: The described embodiments relate generally to liquid crystal displays (LCDs), and more particularly to methods for extending a glass portion of a display to an edge of a display housing. In one embodiment, a thin cover glass layer is provided between a color filter glass layer and an upper polarizer. The thin cover glass layer is supported along an edge of the display by a filler material that can include a foam dam and a glass spacer or adhesive filler. The filler material allows the cover glass layer to be supported without damaging any drivers or circuits located on an underlying thin film transistor glass layer. In another embodiment, a glass spacer circuit with integrated drivers and circuitry on its lower surface can support the cover glass along the edge of the display.

Abstract: A display may have a backlight unit that provides backlight illumination. The backlight unit may include a light guide that distributes light through the display. The light guide may include opposing first and second edges. A first light source such as a first row of light-emitting diodes may emit light into the first edge and a second light source such as a second row of light-emitting diodes may emit light into the second edge. In a normal viewing mode, both light sources are active and backlight illumination is provided over a normal range of angles. In a restricted angle-of-view mode, only one light source is active and backlight is emitted in a more concentrated fashion over a restricted range of angles. In a high luminance restricted angle-of-view mode, the active light source is driven at an elevated level.
Abstract translation: 显示器可以具有提供背光照明的背光单元。 背光单元可以包括通过显示器分配光的光导。 光导可以包括相对的第一和第二边缘。 诸如第一排发光二极管的第一光源可以将光发射到第一边缘中，并且诸如第二排发光二极管的第二光源可以将光发射到第二边缘。 在正常观看模式下，两个光源都是有效的，并且在正常的角度范围内提供背光照明。 在受限制的视角模式中，只有一个光源处于活动状态，并且在限制的角度范围内以更集中的方式发射背光。 在高亮度限制视角模式中，主动光源以升高的水平被驱动。
