Abstract
The present invention discloses a plasma display panel driving method without a transparent electrode. The present invention comprises steps as follows: discharging between two general bus electrodes; improving the step voltage in an addressing period of a maintaining electrode X from 100V-120V to 170V-190V; improving the maintaining pulse voltage and the erasing pulse voltage from 160V-180V to 220V-240V; expanding the width of the first maintaining pulse from 28 us-32 us. The present invention solves the problem of unstable discharge caused by not adopting a transparent electrode to guarantee the normal operation of a PDP display screen by increasing the driving voltage.
Description
Technical field
The present invention relates to a kind of driving method of plasma display PDP display screen, particularly a kind of driving method that does not adopt the PDP display screen of transparency electrode.
Background technology
Present PDP such as main flow adopt ito transparent electrode, can reduce discharging gap like this, and sparking voltage is reduced, thereby PDP is worked in less voltage range, and work can be more stable like this, and the picture quality of demonstration also can significantly improve.But, adopt transparency electrode can make light transmission rate reduce 30%, and the complex manufacturing technology of transparency electrode, can increase manufacturing cost, and if do not adopt transparency electrode, existing driving method can cause the discharge instability under the driving voltage.
Summary of the invention
The purpose of this invention is to provide a kind of driving method that does not adopt the plasma display panel of transparency electrode, solved and do not adopted transparency electrode can cause discharge problem of unstable under the driving voltage.
The technical solution adopted in the present invention is, a kind of driving method that does not adopt the plasma display panel of transparency electrode, this method is carried out discharge between two bus B US electrodes, be set at 170V～190V with keeping electrode X electrode at the plateau voltage of address period, with keep electrode X electrode keep pulse voltage and erase pulse voltage is set at 220V～240V, this is kept first width of keeping pulse of electrode X electrode expands to 28us～32us.
Driving method of the present invention, by improving driving voltage, just improve the firing voltage of keeping between electrode X electrode, the scan electrode Y electrode, solve the problem that does not adopt transparency electrode and cause discharge instability, and guaranteed the operate as normal of PDP display screen.
Description of drawings
Fig. 1 be under the existing driving method scan electrode Y electrode, keep electrode X waveform electrode figure;
Fig. 2 is the scan electrode Y electrode that adopts the inventive method, keeps electrode X waveform electrode figure.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
The prebasal plate of plasma display PDP display screen does not adopt transparency electrode, only adopts bus B US electrode, and metacoxal plate adopts general structure.Because not having transparency electrode, discharge is to carry out between two bus B US electrodes, discharging gap at this moment will be far longer than the discharging gap with ito transparent electrode, will cause the unsettled phenomenon of discharge under former driving voltage.Adopt driving method of the present invention, be raised to 170V～190V at the plateau voltage of address period by 100V～120V with keeping electrode X electrode, with keep electrode X electrode keep pulse voltage and erase pulse voltage is raised to 220V～240V by 160V～180V, this first width of keeping pulse of keeping electrode X electrode is expanded to 28us～32us.
Do not have transparency electrode and have only the increase of the caused discharging gap of bus B US electrode, mean the increase of firing voltage, therefore will correspondingly improve the phenomenon that driving voltage could be eliminated discharge instability.Can adopt in address phase and maintenance stage and improve driving voltage, it is constant that address phase is kept the firing voltage that discharges between electrode X electrode, scan electrode Y electrode and the addressing electrode A electrode, and therefore improving driving voltage needs to increase the firing voltage of keeping between electrode X electrode, the scan electrode Y electrode in fact.Driving method of the present invention, improve the voltage in two stages, actual is to improve the firing voltage of keeping between electrode X electrode, the scan electrode Y electrode, and with first width expansion of keeping pulse, be because in address period under this structure very big discharge time-delay is arranged when keeping the phase transition.
From the contrast of the waveform of Fig. 1, Fig. 2 as can be seen, the scan electrode Y electrode under the driving method of the present invention, keep electrode X waveform electrode and can guarantee PDP display screen operate as normal.
