Abstract

A highly reliable plasma display panel (PDP) display device is provided by reducing power consumption in the PDP display device without deteriorating display brightness and by reducing temperature increase. The PDP display device is provided with a PDP (1) having a plurality of electrodes, a driving circuit (2) for supplying the electrode with a drive waveform, a power supply circuit (3) for supplying the drive circuit with power, and a power control circuit (4) for adjusting output power that can be supplied to the electrode of the PDP by controlling a stop period of the power supply circuit, based on the light emitting status of the PDP.

Description

technical field

[0001] The present invention relates to a power reduction technology of a power circuit used in a plasma display panel (Plasma Display Panel) display device. Background technique

[0002] A plasma display panel (hereinafter referred to as "PDP") is commercialized as a color display panel. FIG. 20 is a diagram showing an electrode arrangement and a drive circuit configuration of a commercially available conventional three-electrode AC PDP of the surface discharge type (see, for example, Non-Patent Document 1).

[0003] As shown in FIG. 20, the three-electrode AC type PDP has a structure as follows: electrodes (X electrodes and Y electrodes, or also referred to as sustain electrodes.) that serve as anodes and cathodes are arranged in parallel on the substrate on the front side, and The address electrodes are arranged on the substrate on the back side so as to intersect the sustain electrode pairs. Each intersection point constituting the electrodes is assigne...
