Abstract
Some embodiments provide application, at a beginning of a first display frame, of a first potential to a pixel imaging element, the first potential to reset the pixel imaging element to a reset state, application, during the first display frame, of a second potential to the pixel imaging element, the second potential to set the pixel imaging element to a desired imaging state, and change, at a beginning of a second display frame subsequent to the first display frame, of the second potential to a third potential, the third potential to reset the pixel imaging element to the reset state.
