Claim:
1. A display device, comprising: a pixel array; a first group of gate drivers and a second group of gate drivers each operatively coupled to the pixel array; a data driver operatively coupled to the pixel array to provide frame data to the pixel array; and a control circuit operatively coupled to a gate driver of the first group or the second group, wherein the control circuit is configured to: wherein the control circuit is configured to (i) cause the first group of gate drivers to refresh a first portion of the pixel array at a normal refresh rate, (ii) cause the second group of gate drivers to refresh a second portion of the pixel array at a modified refresh rate, and (iii) when there are different refresh signals concurrently in use in the pixel array, perform compensation on the frame data to mitigate perception of ripples at a refresh boundary.
