摘要： An organic light-emitting diode display may have an array of pixels. The pixels may each have an organic light-emitting diode with a respective anode and may be formed from thin-film transistor circuitry formed on a substrate. A mesh-shaped path may be used to distribute a power supply voltage to the thin-film circuitry. The mesh-shaped path may have intersecting horizontally extending lines and vertically extending lines. The horizontally extending lines may be zigzag metal lines that do not overlap the anodes. The vertically extending lines may be straight vertical metal lines that overlap the anodes. The pixels may include pixels of different colors. Angularly dependent shifts in display color may be minimized by ensuring that the anodes of the differently colored pixels overlap the vertically extending lines by similar amounts.

摘要： A display may have an array of pixels. Each pixel may have a light-emitting diode such as an organic light-emitting diode. The organic light-emitting diodes may each have a reflective electrode such as a metal anode and a partially reflective electrode such as a metal cathode. Emissive material may be formed between the electrodes. The electrodes of each organic light-emitting diode may form an optical cavity. A wrinkled layer may be formed over the optical cavity to reduce sensitivity to process variations associated with forming encapsulation structures for the display. The wrinkled layer may include annealed organic layers. The organic layers may wrinkle during an annealing process at an annealing temperature. The annealed organic layers may include a first organic layer with a glass transition temperature below the annealing temperature and a second organic layer with a glass transition temperature above the annealing temperature.

摘要： An electronic device may include a display having an array of organic light-emitting diode display pixels. Color filter elements may be used to allow the display to present color images. A blue subpixel may be formed using part of an emissive layer and red and green subpixels may share a separate second part of the emissive layer. In four-subpixel designs, a white or yellow subpixel may also share the emissive layer with the red and green subpixels. Tandem diode configurations may be used in which a blue subpixel has two blue diodes connected in series and other subpixels are formed from respective pairs of series-connected diodes. A pixel definition layer may be formed from a light-absorbing material to suppress ambient light reflections.

摘要： An electronic device may be provided with a display. A content generator may generate frames of image data to be displayed on the display. The display may have an array of pixels that emit light to display images. The pixels may contain light-emitting devices such as organic light-emitting diodes, quantum dot light-emitting diodes, and light-emitting diodes formed from discrete semiconductor dies. As a result of aging, the light producing capabilities of the light-emitting devices may degrade over time. The electronic device may have a temperature sensor that gathers temperature measurements and an ambient light sensor. A pixel luminance degradation compensator may apply compensation factors to uncorrected pixel luminance values associated with the frames of image data to produce corresponding corrected pixel luminance values for the display. The compensation factors may be based on aging history information such as pixel luminance history, ambient light exposure, and temperature measurements.

摘要： 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 pixel array may have a diagonal layout and may be covered by vertically oriented lenticular lenses.

摘要： A display device may include a processor that may receive image data, such that the image data may include gray level data and display brightness value (DBV) data for a first pixel of a display. The processor may then determine a gain compensation factor associated with the first pixel based on a correction spatial map, a brightness adaptation lookup table (LUT), the gray level data, and the DBV data. The processor may then determine an offset compensation factor associated with the first pixel based on the correction spatial map, the brightness adaptation lookup table (LUT), the gray level data, and the DBV data. The processor may generate compensated gray level data by applying the gain compensation factor and the offset compensation factor to the gray level data and transmit the compensated gray level data to pixel driving circuitry associated with the first pixel.
