    Abstract: A display may have an array of organic light-emitting diode display pixels. Each display pixel may include a drive transistor coupled in series with one or more emission transistors and a respective organic light-emitting diode (OLED). A semiconducting-oxide transistor may be coupled between a drain terminal and a gate terminal of the drive transistor to help reduce leakage during low-refresh-rate display operations. To compensate for variations in the threshold voltage of the semiconducting-oxide transistor, the magnitude of a high voltage level of a scan control signal provided to the gate terminal of the semiconducting-oxide transistor may be adjusted. Sensing circuitry may be used to sense a display current while displaying a calibration image. The sensed display current may be compared to an expected display current associated with the calibration image. Processing circuitry may update the high voltage level based on the actual display current compared to the expected display current.

    IPC: G09G3/20

    Abstract: A display may have curved edges such as rounded corners. Pixels in the display may be controlled so that the active area of the display has the desired curved edge shape. In order to maximize the apparent smoothness of the curved edge, the display may include circuitry that dims some of the pixels based on their location relative to a spline for the curved edge. The display circuitry may include a multiplication circuit that receives image data as a first input and dimming factors from a gain table as a second input. The image data may include a brightness level for each pixel in the array of pixels. The multiplication circuit may multiply the brightness level for each pixel by its respective dimming factor. This modified image data may then be supplied to the imaging pixels using display driver circuitry.

    Abstract: One embodiment describes an electronic display that displays image frames with a first refresh rate or a second refresh rate, in which the second refresh rate is lower than the first refresh rate; a display driver that writes the image frames by applying voltage to a display panel; and a timing controller that receives first image data from an image source, in which the first image data describes a first image frame and a first desired refresh rate equal to the second fresh rate; and that instructs the display driver to apply a first set of voltage polarities to the display panel to display first image frame at the first refresh rate and to apply a second set of voltage polarities to the display the first image frame at the second refresh rate when polarity of inversion imbalance accumulated is equal to polarity of the first set of voltage polarities.

    Abstract: An electronic device that includes processing circuitry configured to generate a frame of image data that has a frame duration is provided. The electronic device includes a display that has a plurality of pixels. Each of the plurality of pixels displays image data from the frame of image data for a pixel emission period that is less than the frame duration. A first pixel of a column of pixels of the plurality of pixels begins displaying the image data from the frame of image data at a first time for a first duration. A second pixel of the column of pixels that is adjacent to the first pixel begins displaying the image data from the frame of image data at a second time for a second duration. The first and second durations are equal to the pixel emission period. The second time begins after the first duration of time.

    Abstract: An electronic device includes an electronic display and processing circuitry. The electronic display includes pixels with behaviors that vary with temperature. As such, the processing circuitry generates image data to send to the electronic display (102) and adjust the image data (52) or vary an operation of the electronic display based at least in part on a predicted temperature effect on at least part of the active area of the electronic display (100). The processing circuitry determines the predicted temperature effect at least in part due to a first heat producing component or changes in content of the image data.

    Abstract: An electronic device may have a display such as an organic light-emitting diode display. Electronic devices may also include a number of sensors such as accelerometers and gaze detection sensors. A graphics processing unit (GPU) may render digital pixel values for pixels in the device display. Frames (F2) with long rendering times may cause latency. To reduce latency, an image frame may be displayed for an extended period of time (68) to wait for the subsequent frame (F2) to finish rendering. Once the subsequent image frame (F2) has finished rendering, the subsequent image frame may be displayed without delay. To increase the lifespan of the display, variable persistence may be used. Sensor data and other factors may be used to dynamically determine persistence for minimal motion blur and maximum display lifespan. Sensor data may also be used to determine refresh rates for different portions of 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.
