Abstract
The present invention relates to a plasma display panel, and more particularly, to a method of displaying the gray scale in a plasma display panel. According to the present invention, a method of displaying gray scales in a plasma display panel having an inverse gamma correction unit that operates using gamma tables includes the steps of allowing the inverse gamma correction unit to match picture signals, which corresponds to an n number of frames (n is a natural number) respectively, to an n number of previously stored gamma tables, allowing the inverse gamma correction unit to perform an inverse gamma process on the picture signals received according to the matched gamma tables to produce real gray scales every frame, and allowing the inverse gamma correction unit to divide the real gray scales every frame by n and then to produce last real gray scales. More fine gray scales can be represented by extending the number of real gray scales. It is thus possible to remove noise and provide a much smooth image.
