Abstract: A flat-panel device is fabricated by a process in which a pair of plate structures (40 and 42) are sealed along their interior surfaces (40A and 42B) to opposite edges (44A and 44B) of an outer wall (44) to form a compartment. Subsequently, exterior support structure (64) is attached to the exterior surface of one of the plate structures (40) to significantly increase resistance of the compartment to bending. Exterior support structure (66) is normally likewise attached to the exterior surface of the other plate structure (42) after the sealing operation. The compartment is then typically pumped down to a high vacuum through a suitable pump-out port (46) and closed. By providing the exterior support structure at such a relatively late stage in the fabrication process, the need for using spacers to support the device against external forces is eliminated or substantially reduced while simultaneously avoiding severe fabrication difficulties that arise in attaching the exterior support structure before the sealing operation.

Abstract: A flat-panel device comprising: a main compartment (70) formed with a first plate structure (40), a second plate structure (42), and a generally annular outer wall (44) that extends between the plate structures; an auxiliary compartment (72) situated outside the main compartment (70), the auxiliary compartment (72) formed with an auxiliary wall (76) that contacts the first plate structure (40) outside the main compartment (70), extends away from the first plate structure (40) and main compartment (70), bends back towards the second plate structure (42), and contacts the second plate structure (42) outside the main compartment (70), the auxiliary compartment (72) connected pressure-wise to the main compartment (70) so that the two compartments reach largely equal steady-state compartment pressures; a getter (74) situated in the auxiliary compartment (72); and control circuitry situated over the first plate structure (40) outside the compartments, the auxiliary wall (76) not extending significantly further away from the first plate structure (40) than the control circuitry.
