Abstract
A method of making a display panel comprising a transparent rigid substrate and an electrode structure held against the rigid substrate by means of a flexible backing comprises the steps of sandwiching the electrode structure between the transparent rigid substrate and flexible backing, sealing the backing to the substrate and evacuating the atmosphere from the sealed sandwich structure. The atmospheric air pressure causes the flexible backing to uniformly press the electrode structure against the transparent rigid substrate. A suitable gas atmosphere and getter device is also disclosed.
Claims7
A method of manufacturing a display panel, comprising the steps of
- positioning an electrode structure against one face of a rigid, glass pane having a window area,
- positioning a substantially impervious, flexible sheet over said electrode structure,
- sealing said sheet to said pane along a continuous area surrounding said electrode structure, and
- reducing the pressure in the space between said sheet and said pane in which said electrode structure is located below the pressure on the external side of said sheet to press said electrode structure against said pane.
A method of manufacturing a flat-panel display, comprising the steps of
- positioning an electrode structure against one face of a rigid panel over a window area in said panel,
- positioning a getter rearwardly of said panel,
- positioning a melleable, gas-impervious metal foil sheet over said getter and said electrode structure
- sealing said sheet to said panel throughout a continuous area surrounding said electrode structure and said getter,
- pumping gas out of the space between said panel and said fail sheet,
- backfilling said space with one or more noble gases while maintaining the pressure in said space below atmospheric pressure, and then
- operating said getter to remove reactive gases from said space and to further reduce the pressure therein.
A method of manufacturing a flat-panel display, comprising the steps of
- positioning an electrode structure against one face of a rigid panel over a window area in said panel,
- positioning a porous, compressible blanket over said electrode structure,
- positioning a getter rearwardly of said panel,
- positioning a malleable, gas-impervious metal foil sheet over said blanket and said getter and said electrode structure,
- sealing said sheet to said panel throughout a continuous area surrounding said electrode structure and said getter,
- pumping gas out of the space between said panel and said fail sheet,
- backfilling said space with one or more nobel gases while maintaining the pressure in said space below atmospheric pressure, and then
- operating said getter to remove reactive gases from said space and to further reduce the pressure therein.
