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: An electronic device may include display pixels and a display cover layer. The display cover layer may be formed from a transparent material such as glass. The display cover layer may have a nanotextured upper surface to improve the optical and mechanical characteristics of the display cover layer. The nanotextured upper surface may include first and second different types of nanostructures. The first type of nanostructures may have a relatively low aspect ratio and a first average height. The second type of nanostructures may be elongated nanostructures with a relatively high aspect ratio and a second average height that is greater than the first average height.

Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.

Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated by a backlight unit that includes an array of light-emitting diodes. A backlight brightness selection circuit may select brightness values for the light-emitting diodes. The backlight brightness selection circuit may select the brightness values based on image data, based on brightness values used in previous image frames, based on device information, and/or based on sensor information. The backlight brightness selection circuit may select the backlight brightness levels to mitigate visible artifacts such as flickering and halo. The backlight levels selected by the backlight brightness selection may be modified by a power consumption compensation circuit. The power consumption compensation circuit may estimate the amount of power consumption required to operate the backlight using the target brightness levels and may modify the target brightness levels to meet maximum power consumption requirements.

Abstract: An electronic device includes a display having an emulation component and a separate calibration component. The emulation component may provide a user of the device with a list of available emulation presets at least some of which is common across a large batch of displays. The calibration component may include at least one factory calibration setting that may be shared among one or more of the emulation presets. The user may optionally add to the list of emulation presets by filling up empty emulation slots in the emulation component. The user may also be given the option to recalibrate the display or to add custom calibration datasets using calibration targets different than factory targets. The custom calibration datasets may be optimized for one or more of the emulation presets. Thus, when the user selects a particular emulation preset, the display may automatically select the desired calibration dataset for optimal performance.

Abstract: An electronic device may have a display mounted in a housing. The housing may have a stand that supports the housing on a support surface or may have other shapes. The display may have pixels that display an image. The display may also have a two-dimensional array of light-emitting devices such as light-emitting diodes that supply backlight illumination for the pixels. An array of temperature sensors may be overlapped by the pixels. Control circuitry may maintain historical backlight aging information during operation of the display. The aging information may include information on output brightness levels of the light-emitting diodes and light-emitting diode operating temperatures.

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.
