    Abstract: System and method for improving displayed image quality of an electronic display that displays a first image frame by applying a first voltage to a display pixel and a second image frame directly before the first image frame by applying a second voltage to the display pixel. A display pipeline is communicatively coupled to the electronic display and receives first image data corresponding with the first image frame, where the image data includes a first grayscale value corresponding with the display pixel. Additionally the display pipeline determines an inversion balancing grayscale offset based at least in part on the first grayscale value when polarity of the first voltage and polarity of the second voltage are the same and determines magnitude of the first voltage by applying the inversion balancing grayscale offset to the first grayscale value to reduce likelihood of a perceivable luminance spike when displaying the first image frame.

    Abstract: The present disclosure relates to various techniques, systems, devices, and methods for driving high resolution monitors while reducing artifacts thereon. Data may be stored on pixels of a display such that a first half of the pixels of the display (e.g., arranged in a checkerboard fashion) have data of a first polarity stored on them during a first half of a frame, then a second half of the pixels of the display have data of a second polarity stored on them during a second half of the frame. In such an arrangement, the polarity used to provide data to the pixels may be switched only one time during each frame. The data provided to drive the second half of pixels may be inverted relative to the first half of pixels. The display may use the dot inversion method to provide overall good image quality, yet operate with reduced power consumption.

    Abstract: An electronic device may have a display that has column driver circuitry for providing data line signals to data lines in an array of display pixels. Gate line signals on gate lines in the array and the data line signals may be used in controlling the array to display images for a user of the electronic device. The column driver circuitry may include voltage divider circuitry such as a chain of resistors with reference voltage nodes. The nodes may be provided with reference voltages from corresponding input pins. During normal operation of the column driver circuitry, a voltage supply may supply a set of column driver voltage divider reference voltages to the input pins. During power state transitions when power supply lines for the column driver circuitry might be subjected to undesirable current surges, the voltage supply may be used in supplying transitional voltages to the input pins.

    Abstract: Devices and methods for providing an indication of an active frame start, while reducing a number of line buffers utilized by conventional systems are provided herein. By way of example, an electronic display panel may include a host device (e.g., a processor) that provides an indication of a pending active frame start. The indication may be provided at a predetermined and fixed time/line interval before the active frame start. Next, a timing controller of the display circuitry may generate a vertical start pulse during vertical blanking based upon the indication and the fixed time/line interval. The vertical start pulse may be used to drive multi-clock integrated row driver circuits.

    Abstract: A method and system are provided for compensating for brightness changes in a display having an array of display pixels. The method includes storing a plurality of look-up tables, where each table has a plurality of brightness signals that provide compensation for a brightness change when the refresh rate is changed during a panel self-refresh. The method also includes using display control circuitry to determine the refresh rate associated with an input signal and to determine a compensation based on the refresh rate. The display control circuitry may, for example, use non-linear interpolation to generate a look-up table for the refresh rate. The display control circuitry may adjust the input signal based on the look-up table to produce an output signal that compensates for a brightness change at the refresh rate. The output signal may be transmitted to the array of display pixels.

    Abstract: Systems, methods, and device are provided to provide inversion techniques for dynamic variable refresh rate electronic displays. One embodiment of the present disclosure describes An electronic display including a display panel that display images with varying refresh rates and a timing controller that receives image data from an image source, determines a counter value, and instructs a driver in the electronic display to apply a voltage to the display panel to write an image on the display panel, in which a negative voltage is applied when the counter value is positive and a positive voltage is applied when the counter value is less than or equal to zero. Additionally, the timing controller update the counter value based at least in part on duration the image is displayed on the display panel, wherein the counter value increases when the voltage is positive and decreases when the voltage is negative.
