Embodiment Construction

[0047] Preferred examples of the present invention will now be described in detail with reference to the accompanying drawings.

[0048] figure 1 is a schematic diagram of an image display method for a PDP according to the first preferred example of the present invention.

[0049] see figure 1 , as a method of visually diffusing the generated gradation flicker, an image display method for a PDP according to a first preferred example of the present invention applies diffusion filtering in initial gradation data determined by an external image signal device to generate 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.

[0050] 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 i...

Abstract

PURPOSE: A method for displaying an image of a plasma display panel and an apparatus thereof are provided, which reduces flicker and false contour noise by diffusing a sub field using a diffusion filter using human visual characteristics. CONSTITUTION: An image of each field displayed on a plasma display panel in correspondence to a 50Hz input image signal is divided into a plurality of sub fields having different weight respectively, and gray level is displayed by assembling weights of the above sub fields. Original gray level is generated on the basis of the input image signal, and a diffusion filter value is determined on the basis of the input image signal. Then, final gray level is generated by applying the diffusion filter value to the original gray level. Gray level data corresponding to the final gray level is generated, and an image is displayed on the plasma display panel according to the gray level data.

Description

[0001] This patent application is a divisional application of the following patent application: [0002] Application number: 02131851.4 [0003] Application date: September 6, 2002 [0004] Title of Invention: Image Display Method and System for Plasma Display Panels technical field [0005] 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 [0006] 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. [0007] In such a PDP, it is necessary to be able to display grayscale to exhi...
