説明

Various motional artifacts appear on PDP images Also a gray scale capability at low luminance levels is not satisfactory These problems can be overcome by increasing the number of sub-fields and the field frequency This paper introduces a driving method with which 900cd/m2 luminance and 600 : 1 dark room contrast were achieved by applying only one reset pulse per TV field An expression of 54 randomly addressable subfields on an AC-PDP was made possible by adopting a 3-phase sustain pulse technique combined with an Address-While-Display drive scheme The technique provided a sixfold increase in field frequency to 360Hz compared to the conventional frequency of 60Hz It was proven by using a 42″ PDP that blurring of moving images was reduced significantly.
