Abstract: A display may have an array of pixels arranged in rows and columns. Display driver circuitry may load data into the pixels via data lines that extend along the columns. The display driver circuitry may include gate driver circuitry that supplies horizontal control signals to rows of the pixels. The horizontal control signals may include emission enable signals for controlling emission enable transistors and scan signals for controlling switching transistors. During an emission phase of operation for the display, the emission enable signal may be pulse-width modulated by the emission control gate driver circuits in the gate driver circuitry to control the output of the light-emitting diodes. The emission control gate driver circuits may be controlled using an emission start signal and a pair of two-phase clocks.

Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

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.
