Positive column cell PDP and its DC mode memory driving (II) : 20cm diagonal panel and TV display

Abstract

It was reported that a TV picture is displayed on a 6cm diagonal DC PDP with positive column cell which was driven by DC mode memory scheme with 0.6 lm/W luminous efficiency. This paper reports followings : A same type 20cm diagonal panel with 0.57 cell pitch displays TV picture. 30 cel1s with wall phosphor shows 1.0 lm/W, luminous efficiency. The life is about 50000h. It is possible to remove vertical contaminate in the DC mode memory by compensating pulse with anode. We shows quantitatively dynamic false outline in the DC mode memory and if we use Kaji et al scanning method the false outline is removed.
