1. An electronic device comprising:
a display pixel;
a first bias voltage supply configured to supply a first bias voltage corresponding to a first subframe of a frame of image data to the display pixel and supply a second bias voltage corresponding to a second subframe of the frame of image data to the display pixel, wherein the first bias voltage differs from the second bias voltage; and
a reset bias voltage supply configured to supply a first reset bias voltage corresponding to the first subframe of the frame of image data to the display pixel and supply a second reset bias voltage to the second subframe of the of the frame of image data to the display pixel, wherein the first reset bias voltage differs from the second reset bias voltage.
