Abstract: An array of pixels in a display may be illuminated by a backlight having an array (36) of light-emitting diodes (38) in an array of respective cells. A reflector (68) is used to reflect light from the light-emitting diodes (38) through the array of pixels. Within the cells, the reflector (68) has cross-sectional profiles that help distribute light (80) emitted from the light-emitting diodes (38) toward edges of the cells. A light diffuser layer (34) for the backlight may have a partially reflective layer (96) such as a thin-film interference filter with an angularly dependent transmission. Within each cell, the reflector (68) may have cross-sectional profiles with portions that are parabolic or elliptical.

Abstract: A display may receive image data to be displayed for a user of an electronic device. Display driver circuitry in the display may include a timing controller that receives the image data. The timing controller can analyze frames of the image data to determine average luminance values for the frames. The display may include an array of organic light-emitting diode display pixels. Each display pixel may include a light-emitting diode. A transistor in each display pixel may be coupled in series with the light-emitting diode between positive and ground power supply terminals. The timing controller can limit peak luminance in the image data that is displayed on the array of display pixels as a function of average luminance. The timing controller can also direct power regulator circuitry to adjust a power supply voltage applied to the positive power supply terminal based on the average luminance.

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: The present disclosure relates generally to a liquid crystal display (LCD) that has a large color gamut. In certain embodiments, the large color gamut in the LCD may be obtained by adding a spectrum-filter into different layers of the LCD. The spectrum-filter may be designed to filter a portion of a color band from a light emitted from one or more light emitting diodes (LEDs) in the LED thereby increasing the color gamut on the LCD.

Abstract: A method and system for temporal dithering of pixels in a display 14. The dithering of the pixels may allow for simulation of 8-bit color from a 6-bit display. Moreover, the dithering of the pixels may be selected to follow a specific pattern to minimize display artifacts, which might otherwise result from interference generated by pixel inversion techniques performed during the pixel dithering. Through application of selective dithering techniques, including utilization of specific dithering patterns, the generation of display artifacts via interference from pixel inversion techniques during the display of an image may be minimized.

Abstract: A lenticular display may be formed with convex curvature. The lenticular display may have a lenticular lens film with lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display. To enable more curvature in the display while ensuring satisfactory stereoscopic display performance, the display may have stereoscopic zones and non-stereoscopic zones. A central stereoscopic zone may be interposed between first and second non-stereoscopic zones. The non-stereoscopic zones may have more curvature than the stereoscopic zone. To prevent crosstalk within the lenticular display, a louver film may be incorporated into the display. The louver film may have a plurality of transparent portions separated by opaque walls. The opaque walls may control the emission angle of light from the display, reducing crosstalk. The louver film may be interposed between the lenticular lens film and the display panel.

Abstract: A display may have a layer of liquid crystal material between a color filter layer and a thin-film transistor layer. Column spacer structures may be formed between the color filter layer and the thin-film transistor layer to maintain a desired separation between the color filter and thin-film transistor layers. The column spacer structures may be formed from polymer structures such as photoresist pillars and may include metal pads. The metal pads may be formed on the upper surface of the thin-film transistor layer or the lower surface of the color filter layer. The photoresist pillars may be formed on a surface in the display such as the lower surface of the color filter layer. Column spacer structures may include main spacer structures, subspacer structures, and intermediate thickness spacer structures to enhance pooling mura and light leakage performance.
