Image display method and system for plasma display panel

摘要

The present invention relates to an image display method and system for a plasma display panel (PDP), in which an image of each field displayed on the PDP corresponding to input image signals is divided into sub-fields of different weights, the sub-fields being divided into two continuous sub-field groups and a weighting value of the sub-field groups being different, and in which the weighting values of the sub-fields are combined to display grays. The method includes generating original grays; determining a diffusion filter value; generating final grays by applying the diffusion filter value to the original grays; generating gray data corresponding to the final grays, the gray data being distributed over the two sub-field groups; and displaying an image on the PDP according to the gray data. The disclosed method and system reduce flicker and contour noise and other display problems associated with the display of 50 Hz Phase Alternating by Line image signals.
