Abstract: A display panel includes a plurality of unit light emission areas (light emission elements) arranged in a matrix. Each unit light emission area is defined by a first discharge cell and a second discharge cell. The second discharge cell has a light-absorbing layer. When the display panel is driven to express an image having a plurality of gradation levels, address discharge is selectively caused in the second discharge cells in accordance with an input image signal. Light leaks to the first discharge cell from the second discharge cell upon the address discharge. This light is used to express the gradation of low luminance. Since luminance difference between gradation levels of a low luminance image is reduced, it is possible to display a high quality, low luminance image.

Abstract: The object is to provide a method for driving a plasma display panel, the method being capable of providing improved display quality. A display cell of the plasma display panel is reset to a light-emitting cell state (or a non-light-emitting cell state) only in the head subfield during the display period of one field. Then, in each subfield, executed is a data write process for applying successively a scanning pulse, for generating a selective erase discharge, to each of the row electrodes in order to change selectively each of the display cells from the light-emitting cell state (non-light-emitting cell state) to the non-light-emitting cell state (light-emitting cell state) in accordance with an input video signal. Also executed in each subfield is a light emission sustain process for applying a train of sustain pulses to each of the row electrodes in conjunction with the scanning pulse, the train of sustain pulses generating a sustain discharge to allow only a display cell in the light-emitting cell state to emit light for the number of times corresponding to a weight of each of the subfields.
