Claims18
A flat-panel display, comprising
- a self-supporting, gas-impervious, rigid glass pane having a peripheral portion surrounding a viewing area therein,
- an electrode display structure positioned adjacent said viewing area of said pane,
- a gas-impervious metallic rear sheet overlying said electrode structure,
- sealing means hermetically sealing said rear sheet to said peripheral portion of said pane throughout a continuous area surrounding said viewing area to provide between said pane and said rear sheet a completely enclosed cavity in which said electrode structure is located,
- the pressure within said cavity being less than the pressure on the external side of said sheet, and
- said rear sheet being in force transmitting relationship with said electrode structure and sufficiently soft and malleable so as to be deformed and pressed toward said pane by the differential pressure across said sheet to exert a force on said electrode structure to press said electrode structure against said pane.
