Abstract: A pixel circuit for an electronic display may include a memory to store a digital data signal indicative of a value within a data range. The pixel circuit may also include a light-emitting diode to emit light based at least in part on the digital data signal. The pixel circuit may also include an initialization transistor to initialize the pixel circuit before the light-emitting diode emits light and a driving transistor to activate based at least in part on the digital data signal.

Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower and higher resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.

The pixel may be driven for a first duration of time according to the first digital data signal and for a second duration of time according to the second digital data signal.

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 an undercut to disrupt continuity of some but not all of the OLED layers. The undercut may be defined by three discrete portions of the pixel definition layer. The undercut may result in a void that is interposed between different portions of the OLED layers to break a leakage path formed by the OLED layers.

Abstract: Efficiently transmitting image data to an electronic display may be provided by skipping regions of the electronic display that display a default value. The electronic display may include a number of pixels, a row driver, and a data driver. The row driver may activate a first subset of the pixels for programming. The data driver may program a default pixel value to respective pixels of the first subset of the pixels for which image data has not been received and may program image data to respective pixels of the first subset of the pixels for which image data has been received.

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 have an array of pixels arranged in rows and columns. Each pixel may have a transistor for controlling the amount of output light associated with that pixel. The transistors may be thin-film transistors having active areas, first and second source-drain terminals, and gates. Gate lines may be used to distribute gate control signals to the gates of the transistors in each row. Data lines that run perpendicular to the gate lines may be used to distribute image data along columns of pixels. The gate lines may be connected to gate line extensions that run parallel to the data lines. The data lines may each overlap a respective one of the gate line extensions. Vias may be used to connect the gate line extensions to the gate lines. The gate line extensions may all have the same length.

Abstract: This application relates to methods and apparatus for refreshing a display device at various frequencies. Specifically, multiple areas of the display device can be refreshed concurrently at different frequencies. In this way, when static content is being displayed in certain areas of the display device, those certain areas can be refreshed at a lower rate than areas displaying dynamic content such as video or animation. By refreshing at lower rates, the energy consumed by the display device and subsystems associated with the display device can be reduced. Additionally, processes for reducing flicker when refreshing the display device at different refresh rates are disclosed herein.
