Abstract: A display may have pixels configured to display images. The pixels may be formed from thin-film transistor circuitry on a substrate. Color filter elements formed from colored polymer such as colored photoimageable polymer may be formed on the substrate. A black matrix formed from black photoimageable polymer may have an array of openings. The colored polymer may have first portions that overlap the black matrix and second portions in the openings that form the color filter elements. In some portions of the pixels, the thin-film transistor circuitry may be interposed between the first portions of the colored polymer and the black matrix. In other portions of the pixels, data lines may be formed that are overlapped by the black matrix and that are interposed between the first portions of the colored polymer and the black matrix.

Abstract: A pixel array may be illuminated with backlight illumination from a backlight. The backlight may include a two-dimensional array of light-emitting diodes, with each light-emitting diode being placed in a respective cell. Different light-emitting diodes may have unique brightness magnitudes based on the content of the given display frame. Driver integrated circuits may control one or more associated light-emitting diodes to have a desired brightness level. The driver integrated circuits may be formed in an active area of the backlight. The driver integrated circuits may be arranged in groups that are daisy chained together. A digital signal (that includes information such as addressing information) may be propagated through the group of driver integrated circuits. To manage thermal performance of the backlight, the backlight may include a thermally conductive layer and/or a heat sink structure. To increase the efficiency of the backlight, the backlight may include one or more reflective layers.

Abstract: A display may have an array of pixels controlled by display driver circuitry. The display driver circuitry may supply the pixels with data signals over data lines in columns of the pixels and may supply the pixels with gate line signals over gate lines in rows of the pixels. The display driver circuitry may have a display driver integrated circuit located on one of the edges of the display. The display driver circuitry may also have gate driver integrated circuits that extend along opposing edges of the display to form a pair of shift registers. Conductive lines in a display substrate may be coupled to opposing ends of the shift registers and to intermediate locations within the shift registers to minimize delays in distributing a gate high voltage signal from the display driver integrated circuit to the shift registers.
