Abstract
We have developed a new cell structure and a new driving method for further improvement of 50-inch XGA-type wide PDPs picture quality. Luminous efficiency, bright room contrast ratio and vertical resolution were improved by adopting "waffle-structured" barrier ribs and black strips. High dark room contrast ratio and overcoming dynamic false contour were achieved by adopting new driving method "CLEAR". "PDP-502HD" released in July 1999 exhibited a high contrast ratio of 560:1 and a high peak luminance of 560 cd/m^2 with these technologies.
