Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] As shown in Figure 1-4.

[0020] A three-electrode driving method for a slot-type plasma display panel, comprising the following steps:

[0021] First, use the metal grid as the common electrode and make it form an AC phase discharge mode with the sustain electrode and the address electrode;

[0022] Secondly, each frame to be displayed is divided into subfields, and each subfield includes a recovery period for erasing discharge and initializing the wall charge distribution in each cell, and an addressing period for generating wall charge distribution in the cell to be ignited according to the display data and a sustain period in which the wall charges accumulated in the cell are distributed and discharged during the sustain address period to continue to emit light;

[0023] Third, during the driving process of the slot-type plasma display pane...

Abstract

A SMPDP three electrodes drive method and device loads control signal at the metal net board in suspension, with the signal keeping in suspension at the removal and maintenance stage. In the period of address searching, it applies voltage signal to the metal net plate to generate a relatively stable electric field, keeping all the discharge units in marginal discharge state, ensuring the unit not being ignited affected by those ignited ones after the completion of the recovery cycle. It avoids the misignition caused by the suspension state of the original metal net plate electrodes in address searching, to improve the plasma display panel overall screen reliability.

Description

technical field [0001] The invention relates to a driving method of a plasma display panel, especially a driving method used in the driving process of a slot-type plasma display panel, in particular to a slot-type plasma display panel capable of avoiding misignition. Electrode drive method. Background technique [0002] The plasma flat panel display (PDP), which emerged in the early 1990s, has attracted widespread attention for its advantages of digitization, large screen, high resolution, high definition, wide viewing angle, thin thickness and light weight. [0003] The existing slot-type plasma display panel (SMPDP) uses two electrodes, which are the sustain electrode (X electrode) on the front substrate and the address electrode (A electrode) on the rear substrate. . During the driving process of the slot-type plasma display panel, the X electrode and the A electrode are perpendicular to each other. In the SMPDP display, during the maintenance period, only positive and ...
