Problems solved by technology

As a result, as the distance from the center of the discharge cell increases, the density and density uniformity of the plasma generating the surface discharge become significantly weaker, thereby reducing discharge efficiency and brightness

Embodiment Construction

[0057] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, in which like reference numerals denote like elements.

[0058] refer to figure 1 , The PDP according to the present invention has a surface facing structure in which a first substrate 1 (hereinafter referred to as "front substrate") and a second substrate 3 (hereinafter referred to as "rear substrate") face each other and are bonded together. A plurality of barrier ribs 5 are provided between the front substrate 1 and the rear substrate 3 to form a plurality of separated discharge cells 7R, 7G, 7B capable of generating plasma discharge. The discharge cells 7R, 7G, and 7B are filled with Ne—Xe gas. Phosphor layers 9R, 9G, and 9B are formed on the inner walls of the respective discharge cells 7R, 7G, and 7B with phosphor materials of R, G, and B primary colors.

[0059] Address electrodes 11 are formed, which extend in the y-axis direction ...

Abstract

A plasma display panel (PDP) that has improved discharge efficiency and luminance includes: a first substrate and a second substrate which are provided to oppose each other; barrier ribs which are provided between the first and second substrates and by which a plurality of discharge cells are partitioned; a phosphor layer formed in each of the discharge cells; address electrodes formed either on the first substrate or on the second substrate; and display electrodes formed on the first substrate to extend in a direction intersecting with the address electrodes. The display electrodes include: at least a pair of first display electrodes which are provided close to both peripheral portions of each discharge cell; and a second display electrode provided between the first display electrodes to cross the discharge cell, the second display electrode facing the first display electrodes on both sides to form at least two discharge gaps within each discharge cell.

Description

technical field [0001] The present invention relates to a plasma display panel (PDP) that displays images by utilizing gas discharge. Background technique [0002] In general, a PDP is a display device in which plasma generated by gas discharge emits vacuum ultraviolet (VUV) light that excites a phosphor layer, and uses red (R), green (G), blue (B) Visible light to display images. A PDP having a large-sized display screen of 60 inches or more can be realized with a thickness of 10 cm or less. Since the PDP is a self-luminous display device similar to a cathode ray tube (CRT), it provides excellent color reproduction and a wide viewing angle. In addition, since the PDP is more favorable than a liquid crystal display (LCD) in terms of manufacturing process, productivity, and cost, it has become popular as a flat panel display for televisions and computers. [0003] An alternating current (AC) PDP includes a rear substrate and a front substrate. The rear substrate has addre...
