Problems solved by technology

The general PDP discharge control voltage waveform is provided with a master reset period in the sustain period in the first subfield, and is provided with a slave reset period in the sustain periods of other subfields. There are following defects in adopting such a PDP discharge voltage control waveform: The farther the other subfields outside the first subfield are from the main reset period in the first subfield, the probability of discharge failure increases, resulting in low discharge problems

Embodiment Construction

[0012] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0013] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0014] A master reset is added in the 5th or 8th subfield. Such parts are more effective in high grayscale areas when the field is all white. Generally speaking, consumers or PDP factories perform audio-visual or inspection on high grayscales, which can effectively solve low discharge / high discharge.

[0015] Progressive misdischarge is checked in the full white field or red, green and blue with heavy load after long-term discharge under the ...

Abstract

The invention discloses a method for preventing false electric discharge of a PDP (plasma display panel) screen, relating to the technology of PDP (plasma display panel) screen, aiming at preventing false electric discharge through program modification under the condition of no circuit superaddition, and solving the false electric discharge in the working process of PDP screen. The technique key point in the invention is as follow: a master reset cycle is added in other sub filed except for the first sub field. The method disclosed by the invention is mainly used for preventing the false electric discharge phenomenon of the PDP screen.

Description

technical field [0001] The invention relates to PDP screen technology, in particular to a method for preventing PDP screen from generating electricity. Background technique [0002] The PDP panel is a display that emits light by gas discharge. Each pixel unit of the PDP screen corresponds to a discharge chamber. The discharge chamber is filled with inert gas, phosphor, X electrode and Y electrode. The discharge control voltage applied between the X electrode and the Y electrode causes the discharge of the inert gas to generate ultraviolet rays. , and the ultraviolet rays irradiate the phosphor powder again, thereby realizing the pixel light emission. [0003] An image displayed by the PDP consists of 8 subfields, and each subfield is divided into an address period and a sustain period. The address periods in the first to eighth subfield periods are the same for a long time, and the number of sustain periods increases sequentially. The first The sustain period of the subfie...
