Abstract

A shadow mask type PDP driving method is provided. At least one subfield is set during displaying one frame image. Each subfield comprises an address period, a sustain period and an erase period. Each sustain period comprises three phases. In the first phase an opposed discharge is performed between the scan electrode and the address electrode. In the second phase a surface discharge is performed between the scan electrode and the sustain electrode. In the third phase an opposed discharge is performed between the sustain electrode and the address electrode.

Description

technical field [0001] The invention relates to a driving method of a shadow mask type plasma display panel, in particular to a cycle display driving method which combines the advantages of the existing opposing discharge driving method and surface discharge driving method, specifically a shadow mask A cyclic display driving method for a plasma display panel. Background technique [0002] The structure of the currently used shadow mask type plasma display panel mainly includes a front substrate, a rear substrate and a shadow mask. Starting from the glass substrate, the front substrate is the scanning electrode, the dielectric layer, and the protective layer formed on the surface of the dielectric layer; the rear substrate is starting from the glass substrate, and is the addressing electrode perpendicular to the scanning electrode, the dielectric layer, and the protective layer formed on the dielectric layer. The protective layer; the shadow mask sandwiched between the front...
