摘要： A plasma display panel that can enlarge the voltage margin and can realize a stable display is provided. The plasma display panel includes first and second display electrodes X, Y for generating surface discharge and address electrodes A that cross the display electrodes via a dielectric layer. In the preparation process of the addressing for forming charge distribution corresponding to display contents, charge forming and charge adjusting are performed. The charge forming generates wall voltage having the same polarity at the same kind of interelectrode of all cells constituting the screen, for three kinds of interelectrodes, an interelectrode XY between the display electrodes, an interelectrode XA between the first display electrode and the address electrode, and an interelectrode YA between the second display electrode and the address electrode. The charge adjusting decreases the wall voltage by applying an increasing voltage that increases continuously or step by step.

摘要： A method for driving an AC type plasma display panel is provided in which time necessary for addressing can be shortened without deteriorating stability of a display. Before the addressing, a reset process is performed by applying an increasing waveform voltage between a reference potential line and a scan electrode so as to equalize charge in all cells. In the addressing, a selection voltage Vya1 having the same polarity as a final applied voltage Vyr2 in the reset process and an absolute value larger than the voltage Vyr2 by a potential difference &Dgr;Vy is applied between a scan electrode corresponding to a selected row and the reference potential line.

摘要： The present invention enables a liquid crystal display device using LEDs as a light source to reduce uneven brightness, increase efficiency of heat discharged from the LEDs, and provide area brightness control. The liquid crystal display device includes a liquid crystal display panel and a backlight. The backlight includes a light guide panel and a plurality of LEDs arranged on a line. The light guide panel includes a concave portion extending in a longitudinal direction of the light guide panel. A large number of LEDs are placed in the concave portion of the light guide panel. The plurality of LEDs arranged on a line emit light alternately in opposite directions. This configuration allows for uniform brightness distribution without forming a large number of concave portions in the light guide panel. Further, this configuration also allows for area brightness control by controlling a large number of LEDs by group.
