Abstract: A display may have an array of pixels controlled by display driver circuitry. Gate driver circuitry supplies gate line signals to rows of the pixels. The gate driver circuitry may include blocks of gate driver circuits each having an output coupled to a respective one of the gate lines. The gate driver circuits of each block are coupled in a chain to form a shift register. Each block has a local block-level gate start pulse generator. The display driver circuitry has a display driver circuit that supplies a gate start pulse clock to each of the local block-level gate start pulse generators. The local block-level gate start pulse generators create gate start pulses that are applied to the first gate driver circuit in each shift register. The display driver circuit may delay the gate start pulse clock when it is desired to implement an intraframe pause.

Abstract: A display may include an array of pixels such as light-emitting diode pixels. The pixels may include multiple circuitry decks that each include one or more circuit components such as transistors, capacitors, and/or resistors. The circuitry decks may be vertically stacked. Each circuitry deck may include a planarization layer formed from a siloxane material that conforms to underlying components and provides a planar upper surface. In this way, circuitry components may be vertically stacked to mitigate the size of each pixel footprint. The circuitry components may include capacitors that include both a high-k dielectric layer and a low-k dielectric layer. The display pixel may include a via with a width of less than 1 micron.

Abstract: A display may include an array of pixels. A pixel can include an organic light-emitting diode, up to three thin-film transistors, and up to two capacitors. The pixel can include a drive transistor, an emission transistor, and a select transistor. The select transistor can be used to apply a reference voltage to the gate of the drive transistor during a global reset phase and during a global threshold voltage sampling phase and can also be used to apply a data voltage to the gate of the drive transistor during a data programming phase. The drive transistor can receive a power supply voltage that toggles between a low voltage during the global reset phase and a high voltage during other phases of operation. Configured and operated in this way, the pixel need not include separate dedicated anode reset and initialization transistors.

Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have a steep sidewall, a sidewall with an undercut, or a sidewall surface with a plurality of curves to disrupt continuity of the OLED layers. A control gate that is coupled to a bias voltage and covered by gate dielectric may be used to form an organic thin-film transistor that shuts the leakage current channel between adjacent anodes on the display.

Abstract: An electronic device may have a display and a gaze tracking system. The electronic device may display images on the display that have a higher resolution in a portion of the display that overlaps a gaze location than other portions of the display. Timing controller circuitry and column driver circuitry may include interpolation and filter circuitry. The interpolation and filter circuitry may be used to perform nearest neighbor interpolation and two-dimensional spatial filtering on low resolution image data. Display driver circuitry may be configured to load higher resolution data into selected portions of a display. The display driver circuitry may include low and high resolution image data buffers and configurable row driver circuitry. Block enable transistors may be included in a display to allow selected blocks of pixels to be loaded with high resolution image data.
