    Abstract: A display may have an array of organic light-emitting diode display pixels. Each display pixel may have a light-emitting diode that emits light under control of a drive transistor. Each display pixel may also have control transistors for compensation and programming operations. Each display pixel may have six thin-film transistors and one capacitor. One of the six transistors may serve as the drive transistor and may be compensated using the remaining five transistors and the capacitor. The capacitor may have a first terminal coupled to the gate of the drive transistor and a second terminal coupled to the light-emitting diode. In one embodiment, two scan control signals and two emission control signals may be used for each row of display pixels. In another embodiment, a single scan control signal and a single emission control signal may be formed for each row of display pixels.

    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: A display may include an array of pixels. Each pixel in the array includes an organic light-emitting diode coupled to a drive transistor, a data loading transistor, a first capacitor for storing data charge, and a second capacitor. During a data programming phase, the data loading transistor may be activated to load in a data value onto the first capacitor. After the data programming phase, the second capacitor may be configured to receive a lower voltage, which extends a threshold voltage sampling time for the pixel. Configured and operated in this way, the temperature luminance sensitivity of the display can be reduced.

    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 measure a transistor threshold voltage for a pixel. The threshold voltage may be sampled by controlling the pixel to sample the threshold voltage onto a capacitor at the pixel. The pixel may include at least one semiconducting-oxide transistor, silicon transistors, and a light-emitting diode. The diode may be coupled to a data line that can be used for both data loading and compensation sensing operations. Reset operations may be performed after data programming and before emission to reset the anode voltage for the diode.

    Abstract: A display has rows and columns of pixels (22). A data line (Dn) in each column provides image data signals to the pixels of that column. Each row has first and second control lines (select[m], monitor[m]) coupled to the gates of first and second respective transistors (SE, MO) in each pixel. A third transistor in each pixel servea as a drive transistor (DR) and is coupled in series with a light-emitting diode (30) between positive and ground power supply voltages (VDD, VSS). A display driver circuitry in the display characterizes each of the light-emitting diodes in a column using the data line in an adjacent column from that light-emitting diode. Each of the drive transistors in a column is characterized using the data line in that column and the data line in an adjacent column.
