Abstract: A method for driving a display device includes driving a first pixel circuit based on first and second fields of a frame, and driving a second pixel circuit based on first and second fields of the frame. The first field of the first pixel circuit overlaps the second field of the second pixel circuit. The second field of the first pixel circuit overlaps the first field of the second pixel circuit. Operations performed in the first field include storing a gray scale data voltage, and operations performed in the second field include supplying an amount of current to a light emitter based on the stored gray scale data voltage. The first and second pixel circuits are in adjacent rows of the display device.
