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.

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: The disclosure describes procedures for dynamically employing a variable refresh rate at an LCD display of a consumer electronic device, such as a laptop computer, a tablet computer, a mobile phone, or a music player device. In some configurations, the consumer electronic device can include a host system portion, having one or more processors and a display system portion, having a timing controller, a buffer circuit, a display driver, and a display panel. The display system can receive image data and image control data from a GPU of the host system, evaluate the received image control data to determine a reduced refresh rate (RRR) for employing at the display panel, and then transition to the RRR, whenever practicable, to conserve power. In some scenarios, the transition to the RRR can be a transition from a LRR of 50 hertz or above to a RRR of 40 hertz or below.
