Plasma display panel drive method and plasma display device

Abstract

Disclosed is a plasma display panel drive method, wherein one field is configured using multiple sub-fields having a write-in period during which write-in discharge is caused, a sustain period during which sustain discharge is caused by applying a voltage to the data electrode and by alternately applying a sustain pulse corresponding to the luminance weight to the scan electrode and the sustain electrode, and an erase period during which erase discharge is caused by applying a prescribed voltage to the scan electrode and the sustain electrode, wherein during the erase period, erase discharge is selectively caused only in the discharge cells in which write-in discharge is caused during the immediately previous write-in period, and wherein during the sustain period of at least one sub-field, a voltage lower than the voltage applied to the data electrode of the discharge cell coated with a phosphor emitting red light is applied to the data electrode of the discharge cell coated with a phosphor emitting green light.

Description

technical field [0001] The present invention relates to a driving method of an AC surface discharge plasma display panel and a plasma display device. Background technique [0002] A plasma display panel (hereinafter referred to as "panel") has a plurality of discharge cells having scan electrodes, sustain electrodes, and data electrodes, and excites red, green, and blue colors by using ultraviolet rays generated by gas discharge in the discharge cells. The phosphor emits light to perform color display. [0003] As a method of driving the panel, there is generally a subfield method, that is, a plurality of subfields having an initialization period, a writing period, and a sustaining period are used to form one field, and grayscale display is performed by combining the subfields that emit light. Methods. An initializing operation is performed in an initializing period of each subfield, an addressing operation is performed in an addressing period, and a sustaining operation i...

Problems solved by technology

Therefore, if the forced initialization operation is simply omitted, there is a problem that the address discharge does not occur or the discharge delay time of the address discharge becomes too long, so that the address operation becomes unstable, and normal image display cannot be performed.

In addition, there is another problem that the variation in the discharge characteristics of each discharge cell cannot be absorbed, and the setting boundary of the driving voltage becomes narrow.
