Compensation method for improving the image quality of a plasma display panel

摘要

A compensation process for improving color saturation and image quality of a plasma display panel (PDP) comprises the steps of a) calculating the brightness of a visible light generated by environment light on PDP through performing a numeric operation according to a color mixing theory, and the corresponding light ought to be generated by each of red, green, and blue discharge cells of each of a plurality of pixels on the PDP sufficient to exclude the visible light generated by environment light on PDP; b) increasing or decreasing strength of input image signals of each of said red, green, and blue discharge cells in accordance with the result of calculation; and c) generating light from each of said red, green, and blue discharge cells to eliminate said visible light from causing an adverse effect on said PDP. This can reduce manufacturing cost without modifying the construction of PDP or performing an additional processing thereon.
