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.
