Abstract
A process is disclosed for making grids for flat-panel displays. The screen grids are coated with non-evaporable getter materials and the metal sheet forming the grid is coated with a coating that is as thick as the resulting grid and having at least the same surface area as the image formation zone of the flat-panel display. At least one side of the grid is coated with one or more non-evaporable getter materials and then parts of the sheet thereby coated are selectively removed. Some embodiments of grids produced with such a process are also disclosed.
Claims28
A method for producing a flat panel display having a grid coated with getter materials, comprising:
- providing a metal sheet being as thick as the resulting grid and having a surface area at least as large as the image formation zone;
- coating the metal sheet with one or more non-evaporable getter (NEG) materials at least one side of the metal sheet;
- and
- selectively removing portions of the metal sheet after it is coated with the NEG material.
An article of manufacture for a flat panel display, comprising:
- a metal sheet having a surface area as large as at least an image formation zone for the flat panel display;
- a coating on the metal sheet, the coating comprising at least one non-evaporable getter (NEG) material;
- and
- a plurality of grid holes formed in the metal sheet, the grid holes extending through the coating.
