    Abstract: An organic light-emitting diode display may have an array of pixels. Each pixel may have an organic light-emitting diode with an anode and cathode. The anodes may be formed from a patterned layer of metal. Thin-film transistor circuitry in the pixels may include transistors such as drive transistors and switching transistors. Data lines may supply data signals to the pixels and horizontal control lines may supply control signals to the gates of the transistors. A switching transistor may be coupled between a voltage initialization line and each anode. The voltage initialization lines and capacitor structures in the thin-film transistor circuitry may be formed using a layer of metal that is different than the layer of metal that forms the anodes.

    Abstract: A display may have an array of pixels. Each pixel may have a light-emitting diode that emits light under control of a drive transistor. The organic light-emitting diodes may have a common cathode layer, a common electron layer, individual red, green, and blue emissive layers, a common hole layer, and individual anodes. The hole layer may have a hole injection layer stacked with a hole transport layer. Pixel circuits for controlling the diodes may be formed from a layer of thin-film transistor circuitry on a substrate. A planarization layer may cover the thin-film transistor layer. Lateral leakage current between adjacent diodes can be blocked by shorting the common hole layer to a metal line such as a bias electrode that is separate from the anodes. The metal line may be laterally interposed between adjacent pixels and may be formed on the planarization layer or embedded within the planarization layer.

    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: A display may have an active area with an array of pixels to display images. An inactive area in the display may be formed from an opening in the active area. The inactive area may be enclosed by the pixels in the active area. An inactive border may run along an edge of the inactive area. A grid of positive power supply lines may be used to supply power to the pixels. Initialization voltage lines may be used to distribute initialization voltages to the pixels for use during transistor threshold voltage compensation operations. The inactive border may be free of positive power supply lines and initialization voltages lines. Control signal lines and data lines may pass through the inactive border to supply control signals and data signals respectively to the pixels. The display may have thin-film transistor circuitry with multiple layers of data lines.
