Problems solved by technology

Because in the ready-to-work state, the formation of several full-screen write pulses and erase pulses and the discharge formed during these pulses deteriorate the contrast of the image, and in the erase state, supplementary erase is used simultaneously with the positive polarity pulse pulse, which during addressing causes an increase in the voltage of the control pulse during information addressing

Abstract

The present invention discloses a control method for AC gas discharge display screen. Before entering the stand-by state and after entering the stand-by staet, erasing is performed so that the pulse number is decreased during the stand-by state to raise the contrast of image. During the display state and while adding the first pulse to the scanning display electrode to maintain discharge, accessory pulse is applied to the common display electrode to raise the control reliability of the display screen.

Description

technical field [0001] The invention belongs to the technical field of gas discharge, and in particular relates to a control method of an AC gas discharge display screen, which can be used in a display system containing an AC gas discharge display screen (PDP), including a color TV video module and a spliced ​​display screen. Background technique [0002] According to the literature search conducted by the applicant, the prior art materials related or close to this patent application include the following: [0003] 1. Known a kind of alternating gas discharge display screen (PDP) with parallel, coplanar and grouped scanning display electrodes (selectable display electrodes) and common display electrodes and addressing electrodes perpendicular to the display electrodes control method. This method includes: adding a control pulse and a discharge sustaining pulse to the electrode during the half-selected addressing working state, the full-selecting addressing working state and...
