Abstract

The present invention relates to a plasma display apparatus for displaying TV images and a method for processing image thereof. The plasma display apparatus according to the present invention comprises a gray-level signal division part for dividing a gray-level signal during one frame into a first gray-level signal and a second gray-level signal, a high pass filter filters the first gray-level signal through high frequency bandwidth and a low pass filter filters the second gray-level signal through low frequency bandwidth. As a result, both flicker and a dual-image phenomenon is reduced.

Description

[0001] This application claims priority from Korean Application No. 10-2005-0002669, filed Jan. 11, 2005, the entire contents of which are hereby incorporated by reference. technical field [0002] The invention relates to a plasma display panel, in particular to a plasma display device for eliminating flicker and double image on the display panel and an image processing method thereof. Background technique [0003] Usually in a plasma display panel, the partition formed between the front substrate and the rear substrate is composed of unit cells, each of which is filled with an inert gas, including a primary luminescent gas such as neon, helium or their mixed gas and a small amount of of xenon. When emitting light due to a high-frequency voltage, the inert gas emits vacuum ultraviolet rays to cause the phosphor to emit light so that an image is generated on the display panel. Such a display panel is attracting attention as a next-generation display device because it can be...
