Title:
METHOD OF DRIVING AC DISCHARGE DISPLAY
Document Type and Number:
WIPO Patent Application WO/1999/018561
Kind Code:
A1
Abstract:
A method of maintaining/driving the discharge of an AC discharge display in which at least one of a pair of discharge electrodes is covered with a dielectric layer. A pulse Vy is a narrow width pulse whose pulse width is shorter than a period for which the priming effect of generated charged particles or quasi-stable atoms persists in a discharge space. A pulse Vx is a wide width pulse which is generated before the priming effect produced by the pulse Vy disappears and at about the time when the pulse Vy is generated and has a pulse width long enough for the discharge to stop due to wall charges generated on the dielectric layer. The pulses Vx and Vy are continuously applied between the pair of electrodes to generate a sustained discharge and the influence of the collision of ions against the discharge electrodes and the phosphor is reduced.
