    Abstract: An electronic device may include a display having an array of display pixels on a substrate. The display pixels may be organic light-emitting diode display pixels or display pixels in a liquid crystal display. In an organic light-emitting diode display, hybrid thin-film transistor structures may be formed that include semiconducting oxide thin-film transistors, silicon thin-film transistors, and capacitor structures. The capacitor structures may overlap the semiconducting oxide thin-film transistors. Organic light-emitting diode display pixels may have combinations of oxide and silicon transistors. In a liquid crystal display, display driver circuitry may include silicon thin-film transistor circuitry and display pixels may be based on oxide thin-film transistors. A single layer or two different layers of gate metal may be used in forming silicon transistor gates and oxide transistor gates. A silicon transistor may have a gate that overlaps a floating gate structure.

    Abstract: A display may be provided with integral touch functionality. The display may include a common electrode layer having row electrodes arranged in rows and column electrodes interposed between the row electrodes of each row. The row electrodes may be electrically coupled by conductive paths. The row and column electrodes may be coupled to touch sensor circuitry that uses the row and column electrodes to detect touch events. Each electrode of the common electrode layer may cover a respective portion of an array of pixels. Each pixel of the display may have a respective aperture. The conductive paths that electrically couple row electrodes of the common electrode layer may cover or otherwise block some light from passing through pixels, resulting in reduced apertures. Dummy structures may be provided for other pixels that modify the apertures of the other pixels to match the reduced apertures associated with the conductive paths.

    Abstract: A display such as a liquid crystal display has a display substrate that includes a layer of liquid crystal material sandwiched between a color filter layer and a thin-film-transistor layer. An oversized polarizer is laminated to the surface of the display substrate. Laser-based polarizer trimming equipment is used to trim away excess portions of the polarizer from the display substrate. A thickness gauge gathers thickness information from the laminated polarizer and display substrate. The thickness information is used to adjust the position of a laser relative to the polarizer during polarizer trimming operations. The laser beam moves along a cutting path that is unique to the display substrate. A vision system performs an inspection to determine whether the display substrate is damaged following polarizer trimming operations. Based on the inspection, laser parameters may be adjusted prior to performing polarizer trimming operations on additional polarizers and display substrates.

    Abstract: An electronic device is provided with a display such as a liquid crystal display. The display has a layer of liquid crystal material sandwiched between an upper display layer such as a color filter layer and a lower display layer such as a thin-film-transistor layer. An upper polarizer is formed on the upper surface of the color filter layer. A lower polarizer is formed on the lower surface of the thin-film-transistor layer. To protect display layers such as the color filter layer and the thin-film-transistor layer, a coating is deposited on a peripheral edge of the display layer. A laser is used to cut through portions of the polarizer that overhang the display layer while also cutting through the coating on the peripheral edge of the display layer. Following laser trimming operations, the coating is flush with an edge surface of the polarizer.

    Abstract: An electronic device is provided with a display such as a liquid crystal display mounted in an electronic device housing. The display has a layer of liquid crystal material sandwiched between an upper display layer such as a color filter layer and a lower display layer such as a thin-film-transistor layer. An upper polarizer is formed on the upper surface of the color filter layer. A lower polarizer is formed on the lower surface of the thin-film-transistor layer. To protect display layers such as a glass color filter layer substrate for the color filter layer from damage during polarizer trimming operations, a coating is deposited on a peripheral edge of the glass color filter layer substrate. The coating may be formed from an elastomeric polymer such as silicone and may remain in place or may be removed following trimming operations.
