Abstract
A frame of a video signal is divided into a plurality of sub-frames. Each of the sub-frames is composed by an address period for selecting light emitting pixels or light non-emitting pixels at every scanning line in accordance with a pixel data, and a discharge sustaining period for causing a light emitting pixel to emit at a number of times in accordance with weighting of each sub-frame. A plurality of sub-frames are adjacently disposed to form a sub-frame block. A reset period is provided in a first sub-frame of the sub-frame block so as to initialize all pixels prior to the address period.
