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 touch screen may be formed from a display and perimeter touch electrodes. Touches detected at one or more of the perimeter touch electrodes can be imputed to touch on a region of the display of the touch screen adjacent to the perimeter touch electrodes. In some examples, the perimeter touch electrodes comprise segmented frit metal arranged around the perimeter of the display (e.g., frit metal used to encapsulate the display). In some examples, the perimeter touch electrodes can be coupled to one or more touch sensing circuits via switching circuitry. In some examples, the switching circuitry can be operated based on control signals shared with the display circuitry.
