9. The electronic device of claim 8 , comprising a fourth frame of image content similar to the third frame of image content, wherein the display is configured to operate at the first refresh rate due to the similar image content of the third frame and the fourth frame.

10. The electronic device of claim 1 , wherein the display is configured to transition from the first frame of image content to the second frame of image content based on a clock emission signal.

11. An electronic display comprising:

12. The electronic display of claim 11 , wherein the display driver circuitry is configured to sequence down the refresh rate from the second refresh rate to the first refresh rate during the period of time.

13. The electronic display of claim 11 , wherein the display pixel comprises a native hysteresis, and after the period of time, hysteresis effects of the display pixel level out.

14. The electronic display of claim 13 , wherein increased sampling of the native hysteresis eliminates the hysteresis effects of the display pixel, and wherein the second refresh rate eliminates the hysteresis effects of the display pixel.

15. A method for operating an electronic display in a low refresh rate mode, the method comprising:

displaying, via display driver circuitry, a first frame of image content at a first refresh rate by driving a display pixel of the electronic display;

determining, via the display driver circuitry, a second frame of image content for display on the electronic display is different from the first frame of image content;

driving, via the display driver circuitry, the display pixel to display the second frame of image content by increasing a refresh rate for a period of time; and

after the period of time, driving, via the display driver circuitry, the display pixel to display the second frame of image content at the first refresh rate.

16. The method of claim 15 , wherein increasing the refresh rate comprises driving the display pixel to generate a plurality of image frames equivalent to the second frame of image content.

17. The method of claim 16 , comprising sequencing the increased refresh rate back down to the first refresh rate by changing a timing of each of the plurality of image frames, wherein the first refresh rate is a low refresh rate.

18. The method of claim 15 , comprising:

programming, via the display driver circuitry, image data onto the display pixel, wherein the image data comprises a clock emission signal configured to control a timing of the increased refresh rate and the first refresh rate; and

driving, via the display driver circuitry, the display pixel to generate the second frame of image content based on the image data and the clock emission signal.

19. The method of claim 18 , wherein the display pixel is configured to generate a plurality of image frames based on the image data and the clock emission signal, wherein the clock emission signal tapers the increased refresh rate to the first refresh rate.

20. The method of claim 15 , comprising:

determining, via the display driver circuitry, the second frame of image content is the same as the first frame of image content; and

driving, via the display driver circuitry, the electronic display to display the second frame of image content at the first refresh rate.
