Abstract: A plasma display device and a method for driving a Plasma Display Panel (PDP), which can reduce power consumption without causing display malfunction or reducing image quality, are provided. When the input of an image signal is stopped or when an input image signal is in an entirely-black image state, the application of a drive pulse for driving the PDP is stopped. Here, when the input of the image signal is resumed or when the input image signal switches from the entirely-black image state to a normal image state, the absolute value of a peak potential of the drive pulse or the pulse width thereof is increased to increase the strength of discharge until a predetermined period elapses after the resumption or switching and then the absolute value of a peak potential of the drive pulse or the pulse width is returned to a normal absolute value or a normal pulse width.

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.
