Embodiment Construction

[0042] Preferred examples of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] FIG. 1 is a schematic diagram of an image display method for a PDP according to a first preferred example of the present invention.

[0044] Referring to FIG. 1 , as a method of visually diffusing the generated gray scale flicker, an image display method for a PDP according to a first preferred example of the present invention in initial gray scale data determined by an external image signal A diffusion filter is applied to produce the final grayscale data. The diffusion filter includes an even-field diffusion filter 10 applied to even-field grayscale data, and an odd-field diffusion filter 20 applied to odd-field grayscale data.

[0045] Preferably, gradation data conversion via the even-field diffusion filter 10 and gradation data conversion via the odd-field diffusion filter 20 are performed so that signal processing can be performed in o...

Abstract

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.

Description

technical field [0001] The present invention relates to an image display method and system for a plasma display panel. The present invention relates to a method for reducing flicker, contour noise, interference patterns, and other such problems when realizing an image by inputting a 50 Hz progressive inversion image signal. An image display method and system for a plasma display panel. Background technique [0002] A plasma display panel (PDP) is a display device in which a plurality of discharge cells are arranged in a matrix, and the discharge cells are selectively illuminated to restore image data input as electrical signals. [0003] In such a PDP, it is necessary to be able to display grayscale to exhibit the performance of a color display device. To achieve this, a grayscale implementation method is used in which a single field is divided into a plurality of subfields and the subfields are controlled by time-sharing processing. [0004] A major concern of designers o...
