Systems and methods for reducing visual artifacts in displays due to refresh rate

Abstract:

Techniques for reducing image artifacts on a display s may include receiving image data, such that the image data includes pixel luminance data for a frame of image data. The technique may also include determining an emission duration for a pixel of the plurality of pixels during a sub-frame of the frame of image data based on the pixel luminance data. The technique may also include determining an emission duration extension to apply to the emission duration associated with the sub-frame based on a luminance baseline associated with the sub-frame, a luminance level associated with the sub-frame, and a time period associated with the sub-frame. The technique may then involve sending an emission signal to the pixel, such that the emission signal is configured to cause the pixel to emit light for a duration that correspond to the emission duration and the emission duration extension.
