Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as Figure 1-7 shown.

[0027] A burn-in drive method for a plasma display panel, which is different from the existing burn-in method in that when the plasma display screen is burnt-in, at least three connections with different amplitudes and different widths are applied during the ignition period. Pulse voltage, so that the pulse voltage applied to the display screen for the first time gradually increases to reduce the high-voltage impact on the display screen.

[0028] The waveform of the specific applied voltage can be adopted Figure 1 to Figure 7 The waveform shown, where:

[0029] figure 1 It is one of the new aging driving waveforms of the plasma display screen. During the ignition period, there are three ignition pulse rectangular wave signals with different amplitudes and different widths.

[0030] figure 2 It is the second a...

Abstract

The invention provides an ageing process driven method for plasma display screen which main relates to ageing process used in large-size groove shape plasma display board production process. An ageingprocess driven method only sending a high-voltage firing pulse processes ageing process for display screen before MgO structure parameter stability in PDP production process, this kind ageing processeasy lead to spark phenomenon for some pixel points with unstable parameter, and causes pixel point burnout, reduces producing screen rate. To prevent spark phenomenon in ageing process efficiently,the method provided by the invention changes firing pulse into three pulse signals with various width and breadth during firing, and pulse voltage primary impressed on the display screen is increasedgradually, and high voltage shock to display screen is reduced. Accordingly, display quality of the display screen is ensured, good rate of whole screen is increase and production cost is reduced.

Description

technical field [0001] The invention relates to a burn-in driving method of a plasma display screen, in particular to a burn-in drive method of a large-size slot-type plasma display screen, in particular to a burn-in drive method of a plasma display screen. 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] At present, the existing PDP screens all use a three-electrode AC plasma flat panel display (AC-PDP). Sustain electrodes (X electrodes) and scan electrodes (Y electrodes), both of which are called display electrodes, address electrodes (A electrodes) are vertically distributed on the rear substrate, and X electrodes and Y electrodes are parallel to each other and connected to A electrodes. Orthogonal. In the AC-PDP display, during the sustain ...
