1. A display, comprising:
an array of pixels configured to display moving content at an animation speed; and
control circuitry configured to:
compare the animation speed to first and second speed thresholds, wherein the second speed threshold is higher than the first speed threshold and wherein the first and second speed thresholds are based on a type of animation being displayed and whether the type of animation involves single-edge movement or multiple-edge movement;
change a frame rate of the display from a first frame rate to a second frame rate when the animation speed is greater than the second speed threshold, wherein the second frame rate is higher than the first frame rate; and
change the frame rate of the display from the second frame rate to the first frame rate when the animation speed is less than the first speed threshold.
