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: 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: 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: 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.
