Plasma display device

Abstract

Provided is a plasma display apparatus capable of reducing power consumption by effectively using charges charged in a plasma display panel and achieving a high luminance by a reduction in reactive power. This plasma display apparatus includes: a plasma display panel in which X electrodes, Y electrodes, and Z electrodes are disposed on a front substrate and address electrodes are disposed on a rear substrate; and an X drive circuit, a Y drive circuit, a Z drive circuit and an address drive circuit for performing discharge light emission by applying a Z pulse between the Z electrode and the X electrode or between the Z electrode and the Y electrode and applying an X (Y) pulse between the X electrode and the Y electrode. The Z drive circuit includes a coil and switches using an LC resonance operation with the capacitance of the plasma display panel, and the Z pulse having a narrow pulse width can be generated by generating a Z pulse in the Z drive circuit.

Description

technical field [0001] The present invention relates to a plasma display device, and in particular to an effective technology applied to a Z driving circuit of a plasma display panel in which a Z electrode is disposed between a slit of an X electrode and a Y electrode on a front substrate. Background technique [0002] For example, a plasma display device has a plasma display panel in which X electrodes and Y electrodes are arranged parallel to each other on a front substrate, and address electrodes are arranged orthogonally on a rear substrate sandwiching a discharge space. As for the electrodes, a Z electrode is arranged in parallel with the X electrode and the Y electrode at a position between the slits of the X electrode and the Y electrode on the front substrate. This plasma display panel is controlled by an X drive circuit, a Y drive circuit, an address drive circuit, and a Z drive circuit (for example, refer to Patent Document 1). In particular, since the trigger pul...

Problems solved by technology

In particular, as shown in FIG. 17, since the Z drive circuit applies a rectangular wave with a narrow pulse width to the plasma display panel, the capacitance, applied voltage, and frequency of the panel are correspondingly lost, so the following problems arise: Increase in power consumption (reactive power), decrease in luminance due to insufficient power necessary for light emission due to increase in reactive power, increase in cost due to increase in circuit scale, etc.
