New address-while-display driving method for high picture quality PDP

We propose a new address-while-display (AWD) driving method to obtain a high contrast ratio and a wide driving margin which is composed of a short ramp reset period, a sustain period and an address period as a basic unit. The short ramp reset (SRR) pulse made it possible to assure the wide operating voltage margin and minimize the background luminance by redistributing the wall charges between address and scan electrode. As a result, a high dark room contrast ratio of 10000 to 1 or more could be obtained with a wide operating voltage margin of 40V for stable addressing operation. An improved moving picture quality could be obtained by reducing the dynamic false contour through the alternating subfield arrangement (ASA) method without any other additional image processing.
