    Abstract: Devices and methods for reducing or eliminating image artifacts are provided. By way of example, a method of preventing an occurrence of an image artifact on a display panel may include generating a first gate signal to be supplied to a first gate of a first transistor, generating a second gate signal to be supplied to a second gate of a second transistor, and adjusting a falling edge rate of the first gate signal or a rising edge rate of the second gate signal to reduce a voltage drop associated with row pixels of the display panel. Adjusting the falling edge rate of the first gate signal or the rising edge rate of the second gate signal include decreasing the falling edge rate of the first gate signal or the rising edge rate of the second gate signal during a period of time in which the first gate signal falls.

    Abstract: Methods and devices employing mura prevention circuitry, are provided. In one example, a method may include supplying a first voltage pathway between a common electrode driver and a common electrode of an electronic display device and supplying a second voltage pathway between the common electrode driver and ground. Mura prevention circuitry may be supplied that activates the first voltage pathway when the electronic display device is turned on and an activation gate signal is provided from a gate corresponding to the common electrode driver. Further, the mura prevention circuitry may activate the second voltage pathway when the electronic display device is turned off or no activation gate signal is provided from the gate corresponding to the common electrode driver.

    Abstract: A display may have an array of display pixels to display images. Digital display data may be received by a digital-to-analog converter. The digital-to-analog converter can convert the digital display data to analog display data for the display pixels. The magnitudes of the analog display data signals that the digital-to-analog converter provides to the display pixels can be controlled by a control signal such as a reference voltage received by the digital-to-analog converter. A brightness controller may have multiple peak luminance control profiles. A brightness setting may be processed by a look-up table to produce information identifying a selected one of the peak luminance control profiles. The brightness controller may use the selected peak luminance control profile and average frame luminance for the digital display data to produce the reference voltage that controls the digital-to-analog controller.

    Abstract: A system, method, and device for increasing uniformity between displays incorporating components from different manufacturers. Incorporating components from different manufactures in different displays may cause the different displays to appear differently even under similar conditions. By modifying the operating parameters used to drive the display according to performance characteristics for various conditions, displays incorporating components from different manufacturers may be configured to produce a substantially similar picture under similar conditions. The various conditions may include stimulus information, such as temperature or touch activity.

    Abstract: An electronic device may have a display with an array of pixels. The device may have an array of components such as an array of light sensors for capturing fingerprints of a user through an array of corresponding transparent windows in the display. A capacitive touch sensor, proximity sensor, force sensor, or other sensor may be used by control circuitry in the device to monitor for the presence of a user's finger over the array of light sensors. In response, the control circuitry can direct the display to illuminate a subset of the pixels, thereby illuminating the user's finger and causing reflected light from the finger to illuminate the array of light sensors for a fingerprint capture operation. The display may have display driver circuitry that facilitates the momentary illumination of the subset of pixels with uniform flash data while image data is displayed in other portions of the display.

    Abstract: An electronic device may display image content via an electronic display by controlling light emission from display pixels of the electronic display. A processor of the electronic device may receive image data destined for a defective display pixel (e.g., dim pixel, dead pixel). The processor may convert a gray level of the image data into a luminance domain to generate a target luminance that would have been emitted by the defective display pixel had the display pixel not been defective. After selecting a compensation mask, the processor may distribute the target luminance of the defective display pixels to nearby non-defective pixels of the electronic display to conceal the presence of the defective display pixel.
