Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower (L) and higher (M, H) 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.

Abstract: An electronic device may have a display. A gaze detection system may gather information on a user's point of gaze on the display. Based on the point-of-gaze information, control circuitry in the electronic device may produce image data for an image with areas of different resolutions. A full-resolution portion of the image may overlap the point of gaze. Lower resolution portions of the image may surround the full-resolution portion. The display may have a pixel array. The pixel array may include rows and columns of pixels. Data lines may be used to supply data to the columns of pixels in accordance with row selection signals supplied to the rows of pixels. Display driver circuitry may be used to display the image using the pixel array. The display driver circuitry may have row selection circuitry and column expander circuitry that are responsive to a resolution mode selection 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 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 housing and a display in the housing. The display may have one or more curved edges such as curved edges associated with rounded corners in the display and housing. The display may have an array of pixels. The display may include full-strength pixels and may have a band of antialiasing pixels having selectively reduced strengths to visually smooth content displayed along the curved edges. The pixels may be organic light-emitting diode pixels, liquid crystal display pixels, or other display pixels. Organic light-emitting diode pixels may have drive transistors and associated organic light-emitting diodes. Selectively elevated series or opaque light blocking structures of selectively reduced areas may be used to selectively reduce the strength of the antialiasing pixels. Liquid crystal display pixels may include electrodes of different shapes and/or opaque layer openings of different sizes to form antialiasing pixels in desired patterns.

Abstract: A display is provided that includes an array of display pixels and gate driver circuitry for providing data and gate line signals to the display pixels. Gate driver circuitry may include gate driver circuits that generate the gate line signals. A gate driver circuit may include at least a buffer transistor, a bootstrapping capacitor coupled to the buffer transistor, a pulldown transistor coupled in series with the buffer transistor, and an isolation transistor coupled to the gate of the pulldown transistor. The buffer transistor may directly receive a first clock signal, whereas the isolation transistor may directly receive a second clock signal that is complementary to the first clock signal. The pulldown transistor is substantially larger than the buffer transistor. The buffer transistor is substantially larger than the isolation transistor. Configured as such, clock loading is minimized while the pulldown transistor is sized to provide the desired fall time performance.

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: A display may have an array of pixels controlled by display driver circuitry. The display driver circuitry may supply the pixels with data signals over data lines in columns of the pixels and may supply the pixels with gate line signals over gate lines in rows of the pixels. The display driver circuitry may have a display driver integrated circuit located on one of the edges of the display. The display driver circuitry may also have gate driver integrated circuits that extend along opposing edges of the display to form a pair of shift registers. Conductive lines in a display substrate may be coupled to opposing ends of the shift registers and to intermediate locations within the shift registers to minimize delays in distributing a gate high voltage signal from the display driver integrated circuit to the shift registers.

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.
