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.

Abstract: A display may have an array of pixels arranged in rows and columns. Display driver circuitry may be provided along an edge of the display. Data lines that are associated with columns of the pixels may be used to distribute data from the display driver circuitry to the pixels. Gate lines in the display may each have a horizontal straight portion that extends along a respective row of the pixels and may each have one or more non-horizontal segments such as zigzag segments. The non-horizontal portion of each gate line may be connected to the horizontal straight portion of the gate line by a via. The non-horizontal portions may each have portions that are overlapped by portions of the data lines. Dummy gate line structures may be provided on the display that are not coupled to any of the pixels in the display.

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 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 electronic display may include a pixel circuit. The pixel circuit may include memory storage to store data values representative of image data to be depicted via the pixel circuit. The memory storage may also include memory components for storing bits of the data value. The pixel circuit may also include a light-emitting device for emitting light based at least in part on the data value and a controller. The controller may receive the data value and store the bits based on a mapping between the bits and the memory components. The mapping may be determined based on routing one or more of the bits associated with one or more defective memory components of the memory components to one or more other memory components of the memory components. The controller may also drive the light-emitting device to emit light based on the bits stored in accordance with the mapping.

Abstract: A display with an array of pixels may be provided with redundant pixel control circuits. Switching circuitry may be used to couple pixel control circuits to light-emitting diodes for the pixels. The switching circuitry can be configured using control signals from non-volatile memory in decoder circuitry such as thermometer code decoder circuitry. During manufacturing, the display may be inspected for defects. Defective pixel control circuits can be replaced with redundant pixel control circuits so that the display operates satisfactory. The decoder circuitry may supply control signals to the switching circuitry to switch redundant pixel control circuitry into use while bypassing defective pixel control circuits.

Abstract: An electronic display may include an active area having a first pixel formed in the active area, where the first pixel emits light in response to image data. The electronic display may also include a controller to transmit the image data to the first pixel. The first pixel may include an organic light-emitting diode that emits the light in response to the image data, memory to digitally store the image data received from the controller, and driver circuitry to receive the image data from the memory. The driver circuitry may cause the organic light-emitting diode to emit the light in response to the image data.
