Process for the production of plasma displays with distributed getter material and displays thus obtained

Abstract

A manufacturing process for the production of plasma display panels (80) is described which allows to obtain in a simple way displays wherein, in contact with the atmosphere present in channels (C) or cells of the display, getter materials deposits (81, 81', ...) are present.

Description

technical field [0001] The invention relates to a process for manufacturing a plasma display panel with distributed getter material; the invention also relates to a display obtained according to the process of the invention. Background technique [0002] A plasma display panel is known by the abbreviation PDP, which will be used below. [0003] The PDP consists of two planar glass parts, a front one and a rear one, sealed at their peripheries by a low-melting glass glue. In this way, a closed space is formed between the two glass parts, filled with a noble gas mixture and containing the functional components, as detailed below; typically, the noble gas mixture includes neon and xenon, the latter being present in an amount of about 4-15% . [0004] The operating principle of the PDP is based on the conversion of ultraviolet rays from so-called phosphors to visible light when a discharge is generated in a rare gas mixture. To form an image, multiple light sources of small s...

Problems solved by technology

However, also this solution presents a significant constructional difficulty, in fact, in order to deposit the getter selectively only on the top surface of the ribs, a very precise masking operation is necessary to avoid material spreading along the sidewalls. and occupy the area assigned to phosphors (or cover them, if these already exist)
