Embodiment Construction

[0022] The invention will now be described in more detail with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[0023] FIG. 1 is a plan view of a plasma display panel (PDP) 1 . The frit 3 forms between two substrates 2 (one underneath the other) at the peripheral edge of the substrates. The display area 4 is formed inside the glass frit 3 . The visible image is displayed in the display area.

[0024] FIG. 2 is a partially exploded perspective view of a PDP 100 constructed in accordance with one embodiment of the present invention. FIG. 3 is a cross-sectional view of the PDP 100 of FIG. 2 taken along line III-III' of FIG. 2 . FIG. 4 is a cross-sectional view of the PDP 100 of FIG. 2 taken along line IV-IV' of FIG. 3 .

[0025] Referring to FIGS. 2 and 3 , the PDP 100 includes a pair of substrates 110 , a sheet 120 , a first discharge electrode 131 , a second discharge electrode 132 , a frit 140 , grooves 150 , and a phosph...

Abstract

The present invention provides a plasma display panel (PDP) that prevents a frit or a sealing material from entering into a display region during a sealing process of the PDP. The plasma display panel includes a pair of substrates spaced apart from each other by a predetermined gap and facing each other, and a sheet interposed between the pair of substrates. First discharge electrodes and second discharge electrodes are disposed inside the sheet. The second discharge electrodes are spaced apart from the first discharge electrodes. The sheet includes a barrier rib part and a dielectric part. The barrier rib part has a plurality of holes that defines discharge cells together with the pair of substrates. A frit or sealing material is interposed between the dielectric part and each of the pair of the substrates. The frit seals a space formed between the pair of the substrates. A groove is formed on the surface of one substrate of the pair of the substrates. The groove is formed around edge of the substrate outside display region, so that the groove effectively prevent frit from spreading into the display region during manufacturing process of the PDP

Description

technical field [0001] The present invention relates to a plasma display panel (PDP), and more particularly, to a PDP designed to prevent its display area from being contaminated by frit. Background technique [0002] A plasma display panel (PDP), which has replaced a conventional cathode ray tube (CRT) display device, displays images using visible rays generated by applying a discharge voltage to a discharge gas sealed between two substrates. A plurality of electrodes are formed on the substrate, and ultraviolet rays are first generated by applying a voltage through the electrodes. The ultraviolet rays excite phosphors formed in the PDP, resulting in generation of visible light. [0003] Discharge cells of the PDP are formed between barrier ribs formed between two substrates. The discharge electrodes intersect the discharge cells to apply a voltage to the discharge cells. The two substrates are sealed with frit at a predetermined thickness around their edges. The discha...
