Embodiment Construction

[0040] In order to simplify the description and to show the differences and advantages of the present invention over the prior art, the same reference numerals will be used for elements performing the same functions.

[0041] A method of manufacturing a plasma panel according to the invention will now be described, in this case a panel provided with cells arranged in straight rows and columns, in particular with regard to the manufacture of a panel carrying an array of barrier ribs, wherein the The barrier ribs are also straight, in this case the plate detailed is the rear plate.

[0042] The fabrication starts with a soda lime glass plate measuring 254 mm x 162 mm x 3 mm, provided with an electrode array formed of silver conductors, which is itself coated with a conventional dielectric layer baked at 540°C.

[0043] Described below is the fabrication of barrier rib arrays on this plate in order to obtain:

[0044]- a series of continuous, parallel ribs 2 having a thickness o...

Abstract

The panel has two plates forming between them a sealed space filled with discharge gas and partitioned into discharge cells. The cells are delimited between the plates by partitions (3) forming a network and are distributed in lines and columns. The portion of the partition separating any two adjacent cells of the same column has a cavity (51) which is arranged in the thickness of the partition and which emerges at the top of the partition.

Description

technical field [0001] The present invention relates to a plasma panel comprising: two plates, a sealed space is left between the two plates, the space is filled with a discharge gas, and the space is divided into discharge cells, the discharge cells are defined between the plates by barrier ribs forming an array; and at least two arrays of electrodes arranged in such a way that one electrode of each array traverses each cell. Background technique [0002] Document WO 00 / 46832 (FUJITSU), specifically in its Figure 15 and reproduced in the following figure 1 and figure 2 In, a plasma panel of this type is described in which an array of barrier ribs defines a cell 1, said plasma panel comprising: [0003] - a series of narrow ribs 2 that are continuous, parallel and along a first direction; and [0004] - a series of thick ribs 3 that are discontinuous, parallel and along a second direction perpendicular to the first direction. [0005] Here, the narrow ribs define the co...
