Embodiment Construction

[0026] The plasma display panel of the present invention will be described below with reference to the accompanying drawings. 3 is a structural diagram of a plasma display panel in the present invention, and FIGS. 4a to 4c are implementation diagrams of a shutdown signal when the plasma display panel is turned off in the present invention.

[0027] In the present invention, the plasma display panel has: a plurality of address electrodes (X 1 -X k ); a plurality of scanning electrodes arranged in the horizontal direction (Y 1 -Y n ); contains the continuous electrode (Z 1 -Z m ) constitutes a module (60). The scanning electrodes are formed corresponding to the continuous electrodes, one ends of the continuous electrodes are connected to each other, and the same voltage is input during operation.

[0028] Above-mentioned module (60) is made of above-mentioned scanning electrode (Y 1 -Y n ) and continuous electrodes (Z 1 -Z m ) horizontally alternately formed front pane...

Abstract

The plasma display panel drive device finishes the execution of frame while receiving power cut off signal, initializing the unit over one time till the consumption of power inside the capacitor, to avoid the abnormal action of the plasma display panel when the power restarts to ensure the stability of power shutoff. It comprises several electrodes crossed units and the unit sending off signal to the electrode to execute initialization of the power control section, shutting off the power after receiving cut off signal. It can realize stable power shut off, to avoid odd action of plasma display panel when he power is reconnected.

Description

【Technical field】 [0001] The invention relates to a plasma display panel driving device and a driving method thereof. 【Background technique】 [0002] The present invention relates to a plasma display panel driving device and its driving method. The characteristics of this plasma display panel driving device and its driving method are: after receiving the power cut-off signal, the frame in progress is executed and the unit is initialized more than once. Turn off the power, so that the stable power off is completed and the power charged in the capacitor is consumed to prevent the abnormal operation of the plasma display panel when the power is restarted. [0003] A conventional plasma display panel is shown in FIG. 1 , which is a schematic diagram of multiple driving circuit substrates located behind the panel. [0004] A plasma display panel is a display device that uses vacuum ultraviolet rays (VUV) generated during gas discharge inside the panel to collide with phosphors i...
