Abstract
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 the 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 could be obtained with a wide operating voltage margin of 40V for stable address.
