Abstract: A display may have rows and columns of pixels that form an active area for displaying images. A display driver integrated circuit may provide multiplexed data signals to demultiplexer circuitry in the display. The demultiplexer circuitry may demultiplex the data signals and provide the demultiplexed data signals to the pixels on data lines. Gate lines may control the loading of the data signals into the pixels. The display may have a length dimension and a width dimension that is shorter than the length dimension. The data lines may extend parallel to the width dimension and the gate lines may extend parallel to the length dimension such that there are more data lines than gate lines in the display. A notch that is free of pixels may extend into the active area. Data lines extending parallel to the width dimension of the display may be routed around the notch.

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: An electronic device may be provided with an organic light-emitting diode display. The display may include row driver circuitry that provides an emission control signal at an output terminal to display pixels. The emission control signals may enable or disable light emission by the pixels. The row driver circuitry may include a bootstrapping capacitor that stores charge for boosting a gate signal at an intermediate node for a pull-up transistor above a power supply voltage. The row driver circuitry may include a pull-down transistor coupled to the intermediate node. The source terminal of the pull-down transistor may be coupled to the output terminal or an additional pull-down transistor may be stacked with the pull-down transistor to reduce leakage current. Charge pump circuitry may be coupled to the intermediate node to ensure that the intermediate node is maintained at a voltage above the power supply voltage.

Abstract: A display may have an array of pixels formed from thin-film transistor circuitry. The thin-film transistor circuitry may include thin-film layers of dielectric, semiconductor, and metal on a dielectric substrate. Test structures may be formed around the periphery of the substrate to facilitate testing of the thin-film circuitry during manufacturing. The test structures may include test pads that are coupled to the thin-film circuitry by test lines extending from the thin-film circuitry. Following testing, the outermost portions of the display and the test pads on these display portions may be removed by cutting the substrate along a substrate cut line. The test lines may be formed from parallel lines that are shorted together, semiconductor layers, multiple layers of conductive material, and other structures that resist corrosion along the cut line.

Abstract: An organic light-emitting diode display may have an array of pixels. Each pixel may have multiple subpixels of different colors. To avoid undesired color shifts when operating the display, the display may be configured so that subpixels of different colors are not coupled to each other through parasitic capacitances. The subpixels may include red, green, and blue subpixels or subpixels of other colors. Each subpixel may include an organic light-emitting diode having an anode and a cathode. The anode of each organic light-emitting diode may be coupled to a respective storage capacitor. Capacitive coupling between subpixels can be minimized by configuring the subpixel structures of each pixel so that the storage capacitors of the subpixels do not overlap the anodes of other subpixels in the pixel. Anode and capacitor overlap with subpixel data lines may also be reduced or eliminated.

Abstract: An evaporation tool is provided that has an elongated evaporation source with elongated edges that run parallel to a longitudinal axis and shorter edges that run perpendicular to the longitudinal axis. The evaporation source has multiple evaporation sources formed by respective source orifices through which material is evaporated. An evaporation control structure is mounted to the evaporation source to enhance the directionality of evaporated material. A shadow mask is provided that has a rectangular frame for supporting a metal mask layer with a pattern of openings. The evaporation control structure ensures that the evaporated material from the source is evaporated towards the shadow mask. Angled walls attached to the elongated edges, a series of vertical walls that extend between the angled walls in the evaporation control structure, and aligned vertical wall extensions on the frame of the shadow mask are used to block evaporated material following angled trajectories.
