Plasma display panel

Abstract

A plasma display panel for improving a color coordinates correction and a color temperature is disclosed. In the plasma display panel, a vertical barrier rib separates red, green and blue discharge cells from each other in a longitudinal direction. A horizontal barrier rib is provided between the vertical barrier ribs to separate the red, green and blue discharge cells from each other in a wide direction. The horizontal barrier rib has a first horizontal barrier rib provided between the red discharge cells, a second horizontal barrier rib provided between the green discharge cells, and a third horizontal barrier rib provided between the blue discharge cells and having a smaller width than the first and second horizontal barrier ribs.

Description

[0001]This application claims the benefit of Korean Patent Application No. P2003-102178 filed in Korea on Dec. 31, 2003, which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a plasma display panel, and more particularly to a plasma display panel that is adaptive for improving a color coordinates correction and a color temperature.[0004]2. Description of the Related Art[0005]Generally, a plasma display panel (PDP) radiates a phosphorous material using an ultraviolet ray with a wavelength of 147 nm generated upon discharge of an inactive mixture gas such as He+Xe, Ne+Xe or He+Ne+Xe, to thereby display a picture including characters and graphics. Such a PDP is easy to be made into a thin-film and large-dimension type. Moreover, the PDP provides a very improved picture quality owing to a recent technical development. Particularly, since a three-electrode, alternating current (AC) surface-discharge PDP has wal...

Benefits of technology

[0017]Accordingly, it is an object of the present invention to provide a plasma display panel that is adaptive for improving a color coordinates correction and a color temperature.

Problems solved by technology

On the other hand, the PDP adopting the stripe-type barrier rib 24 has disadvantages in that it fails to have a high brightness characteristic because an amount of the visible light amount produced by a radiation of the phosphorous material 26 within the discharge cell is small due to a limitation in its area coated with the phosphorous material and in that a width of the gas flowing path between the upper and lower discharge cells is large due to a non-existence of the structure provided between the barrier ribs 24 at a region where the upper and lower discharge cells are divided, thereby causing a cross talk to lead to a color interference phenomenon between the pixels of the PDP.

However, the PDP in which a pitch between the discharge cells for implementing the red(R), green(G) and blue(B) colors has a non-symmetric structure has a problem in that horizontal pitches of the red(R), green(G) and blue(B) discharge cells are too reduced as a resolution of the PDP goes higher, thereby causing an increase of discharge voltage, a reduction of operation margin and a reduction of brightness / efficiency characteristics.
