Embodiment Construction

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

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

Description

technical field [0001] The invention relates to a driving method of a PDP display screen of a plasma display, in particular to a driving method of a PDP display screen without transparent electrodes. Background technique [0002] The current mainstream and other PDPs all use ITO transparent electrodes, which can reduce the discharge gap and 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 is complicated, which will increase the manufacturing cost. If the transparent electrodes are not used, the existing driving method will cause the discharge under the driving voltage to be unstable. Contents of the invention [0003] The object of the present invention is to provide a driving method of a plasma display screen...
