Embodiment Construction

[0008] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0009] The front substrate of the plasma display PDP display screen does not use transparent electrodes, only bus electrodes, and the rear substrate adopts a common structure. Since there is no transparent electrode, the discharge is performed between the two bus electrodes. At this time, the discharge gap is much larger than the discharge gap with the ITO transparent electrode, which will cause unstable discharge under the original driving voltage. Using the driving method of the present invention, the step voltage of the sustain electrode X during the address period is increased from 100V~120V to 170V~190V, and the sustain pulse voltage and erase pulse voltage are increased from 160V~180V to 220V~240V, and The width of the first sustain pulse is extended to 28us to 32us.

[0010] The increase in the discharge gap caused by the absence of transparent electrode...

Description

Technical field [0001] The invention relates to a method for driving a PDP display screen of a plasma display, in particular to a method for driving a PDP display screen that does not use transparent electrodes. Background technique [0002] The current mainstream PDPs use ITO transparent electrodes, which can reduce the discharge gap and reduce the discharge voltage, so that the PDP can work in a smaller voltage range, so that the work will be more stable and the displayed image quality will be greatly improved. . However, the use of transparent electrodes will reduce the light transmittance by 30%, and the manufacturing process of the transparent electrodes will be complicated, which will increase the manufacturing cost. If the transparent electrodes are not used, the existing driving method will cause unstable discharge under the driving voltage. Summary of the invention [0003] The object of the present invention is to provide a method for driving a plasma display screen th...
