    Abstract: The present disclosure relates to an electronic device that includes a display that has a plurality of scan lines. The display also includes a first data line that has a first number of pixels. The first data line forms a first number of crossovers with the plurality of scan lines. Additionally, the display includes a second data line that has a second number of pixels that is different than the first number of pixels. The second data line forms a second number of crossovers with the plurality of scan lines that is equal to the first number of crossovers.

    Abstract: A display pixel may include an organic light-emitting diode, one or more emission transistors, a drive transistor, a gate setting transistor, a data loading transistor, and an initialization transistor. The drive transistor may be implemented as a semiconducting-oxide transistor to mitigate threshold voltage hysteresis to improve first frame response at high refresh rates, to reduce undesired luminance jumps at low refresh rates, and to reduce image sticking. The gate setting transistor may also be implemented as a semiconducting-oxide transistor to reduce leakage at the gate terminal of the drive transistor. The initialization transistor may also be implemented as a semiconducting-oxide transistor so that it can be controlled using a shared emission signal to reduce routing complexity. The remaining transistors in the pixel may be implemented as p-type silicon transistors. Display pixels configured in this way can support in-pixel threshold voltage compensation and on-bias stress phase to further mitigate the hysteresis.

    Abstract: A touch sensor panel comprising a first touch node electrode of a plurality of touch node electrodes, the first touch node electrode coupled to a first sense connection comprising a first set of traces, the first sense connection configured to have a first resistance per unit length that varies along a length of the first sense connection, and a second touch node electrode of the plurality of touch node electrodes, the second touch node electrode coupled to a second sense connection comprising a second set of traces, the second sense connection configured to have a second resistance per unit length that varies along a length of the second sense connection differently than the first resistance per unit length varies along the length of the first sense connection. An effective resistance of the first sense connection and the second sense connection are equal.

    Abstract: A display pixel is provided that is operable to support hybrid compensation scheme having both in-pixel threshold voltage canceling and external threshold voltage compensation. The display may include multiple p-type silicon transistors with at least one n-type semiconducting-oxide transistor and one storage capacitor. An on-bias stress phase may be performed prior to a threshold voltage sampling and data programming phase to mitigate hysteresis and improve first frame response. In low refresh rate displays, a first additional on-bias stress operation can be performed separate from the threshold voltage sampling and data programming phase during a refresh frame and a second additional on-bias stress operation can be performed during a vertical blanking frame. The display pixel may be configured to receive an initialization voltage and an anode reset voltage, either of which can be dynamically tuned to match the stress of the first and second additional on-bias stress operations to minimize flicker.

    Abstract: A display may include an array of organic light-emitting diode display pixels having transistors characterized by threshold voltages subject to transistor variations. Compensation circuitry may be used to sense a current from selected display pixels. A display pixel may include a drive transistor, a gate setting transistor for driving a reference voltage onto the gate terminal of the drive transistor, a data loading and current sensing transistor for connecting the drive transistor to a data/current-sensing line, a light-emitting diode, an emission control transistor coupled between the drive transistor and the diode, and an anode resetting transistor for selectively resetting the anode terminal of the diode. During pixel conditioning and current sensing operations, the anode resetting transistor may be constantly turned on to ensure that there is no voltage perturbation at the source terminal of the drive transistor, which can help prevent hysteresis-induced current sensing error.

    Abstract: A display may have rows and columns of pixels. Gate lines may be used to supply gate signals to rows of the pixels. Data lines may be used to supply data signals to columns of the pixels. The data lines may include alternating even and odd data lines. Data lines may be organized in pairs each of which includes one of the odd data lines and an adjacent one of the even data lines. Demultiplexer circuitry may be configured dynamically during data loading and pixel sensing operations. During data loading, data from display driver circuitry may be supplied, alternately to odd pairs of the data lines and even pairs of the data lines. During sensing, the demultiplexer circuitry may couple a pair of the even data lines to sensing circuitry in the display driver circuitry and then may couple a pair of the odd data lines to the sensing circuitry.
