Problems solved by technology

Therefore, in the case of representing fade-in or fade-out images, the former method using gamma correction has a problem due to the occurrence of a step phenomenon in R and G colors
[0010] On the other hand, the latter method using asymmetric discharge cells has a problem of occurrence of discharge imbalance due to differences between areas for discharge cells of different colors
These methods also have the problem of misdischarge caused by unbalanced discharge and reduced voltage margin for stable driving
Furthermore, this method increases production cost and reduces visual resolution since a single mask is required for printing R, G, and B phosphor layers

Embodiment Construction

[0033] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0034] figure 1 is an exploded perspective view of a plasma display device according to an embodiment of the present invention.

[0035] The PDP 10 includes a front substrate 10a and a rear substrate 10b integrally bonded with a seal such as frit. A plurality of discharge cells are provided in the PDP. A plasma discharge is generated in the discharge chamber. Vacuum ultraviolet (VUV) light generated by the plasma discharge excites the fluorescent layer. Visible light emitted by the fluorescent layer is used to form an image.

[0036] A plasma display device having a PDP 10 includes: a base plate 14 for supporting a rear substrate of the PDP 10 and mounting a plurality of printed wiring board assemblies 12; a front cabinet 16 arranged in front of the PDP 10; and a rear case 18 arranged in the The rear of the chassis 14 is to surround the PDP 10 and the cha...

Abstract

A Plasma Display Panel (PDP) includes: front and rear substrates facing each other; address electrodes arranged on the rear substrate; barrier ribs arranged between the front and rear substrate to define first, second, and third color discharge cells, the discharge cells being filled with a discharge gas; first, second, and third color layers adapted to be excited by the discharge gas and to emit light; and display electrodes arranged on the front substrate, the display electrodes including non-transparent protrusion electrodes protruding inward from edges of the discharge cells. The non-transparent protrusion electrodes of at least two of the first, second, and third color discharge cells have different areas.

Description

technical field [0001] The present invention relates to a plasma display panel (PDP), and more particularly, to a PDP utilizing non-transparent protruding electrodes protruding inward from edges of discharge cells to improve color temperature and brightness chamber contrast ratio (BRCR). Background technique [0002] A plasma display panel (PDP) is an image forming device that excites phosphor layers using plasma discharge. A predetermined voltage is applied between two electrodes arranged in a discharge space of the PDP to generate plasma discharge. Vacuum ultraviolet (VUV) light generated by the plasma discharge excites the fluorescent layer. Visible light emitted from the fluorescent layer is used to form an image. PDPs are classified into AC, DC, and hybrid PDPs. [0003] The AC PDP includes a pair of front and rear substrates facing each other. Address electrodes are disposed on the rear substrate. A dielectric layer is disposed to cover the...
