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 touch screen display may include gate line driver circuitry coupled to a display pixel array. The display may be provided with intra-frame pausing (IFP) capabilities, where touch or other operations may be performed during one or more intra-frame blanking intervals. In one suitable arrangement, a gate driver circuit may include multiple gate line driver segments each of which is activated by a separate gate start pulse. Each gate start pulse may only be released at the end of an IFP interval. In another suitable arrangement, dummy gate driver units may be interposed among active gate driver units. Gate output signals may propagate through the dummy gate driver units during the IFP internal. In another suitable arrangement, each active gate driver unit may be provided with a buffer portion that protects at least some transistor in the gate driver unit from undesired stress.

Abstract: An electronic device display may have an array of pixel circuits. Each pixel circuit may include an organic light-emitting diode and a drive transistor. Each drive transistor may be adjusted to control how much current flows through the organic light-emitting diode. Each pixel circuit may include one or more additional transistors such as switching transistors and a storage capacitor. Semiconducting oxide transistors and silicon transistors may be used in forming the transistors of the pixel circuits. The storage capacitors and the transistors may be formed using metal layers, semiconductor structures, and dielectric layers. Some of the layers may be removed along the edge of the display to facilitate bending. The dielectric layers may have a stepped profile that allows data lines in the array to be stepped down towards the surface of the substrate as the data lines extend into an inactive edge region.

Abstract: A display may have an array of pixels. The array of pixels may have a shape such as a circular shape or other shape with a curved edge. Display driver circuitry may supply data signals to the pixels using folded vertical data lines and bisected horizontal gate lines. Each folded vertical lines may have a first segment in a left half of the array and a second segment in a right half of the display. Curved coupling segments in an inactive area of the display may be used in joining the first and second segments. Display driver circuits may be provided in top and bottom portions of the inactive area to supply data to respective top and bottom portions of the array. Gate driver output buffers may have different strengths in different rows of the array.

Abstract: A display may include an array of pixels that receive control signals from a chain of gate drivers. The pixels can be formed using semiconducting oxide transistors, whereas the gate drivers can be formed using silicon transistor. Each gate driver may include a shift register subcircuit and an output buffer subcircuit. The shift register subcircuit may include a first set of transistors at least partially controlled by one or more shift register clock signals. The output buffer subcircuit may include a second set of transistors at least partially controlled by one or more output buffer clock signals. The output buffer clock signals can toggle independently from the shift register clock signals. Operated in this way, the shift register clock signals can have pulse widths optimized for stability while the output buffer clock signals can have pulse widths optimized for speed.

Abstract: A display may include an array of pixels that receive control signals from a chain of gate drivers. Each gate driver may include a mix of silicon transistors, one or more semiconducting oxide transistors, and one or more capacitors. The semiconducting oxide transistors can each have a back gate terminal shorted to one of its source-drain terminals, shorted to its front gate terminal, or configured to receive a bias voltage. Configured in this way, the gate driver circuit can exhibit less threshold voltage drift and thus improved device reliability over time.

Abstract: An organic light-emitting diode display may have thin-film transistor circuitry formed on a substrate. The display and substrate may have rounded corners. A pixel definition layer may be formed on the thin-film transistor circuitry. Openings in the pixel definition layer may be provided with emissive material overlapping respective anodes for organic light-emitting diodes. A cathode layer may cover the array of pixels. A ground power supply path may be used to distribute a ground voltage to the cathode layer. The ground power supply path may be formed from a metal layer that is shorted to the cathode layer using portions of a metal layer that forms anodes for the diodes, may be formed from a mesh shaped metal pattern, may have L-shaped path segments, may include laser-deposited metal on the cathode layer, and may have other structures that facilitate distribution of the ground power supply.

Abstract: A display may include an array of pixels. Each pixel in the array may include a drive transistor, emission transistors, a data loading transistor, a gate voltage setting transistor, an initialization transistor, an anode reset transistor, a storage capacitor, and an optional current boosting capacitor. A data refresh may include a initialization phase, a threshold voltage sampling phase, and a data programming phase. The threshold voltage sampling phase can be substantially longer than the data programming phase to decrease a current sampling level during the threshold voltage sampling phase, which helps reduce the display luminance sensitivity to temperature variations.
