Abstract
A method for assembling two parallel plates respectively forming the bottom and the face of a flat display screen including a degassing step of the plates and a vacuum burn-in step. The method includes the steps of subjecting a first plate to a burn-in step by electronic bombardment, moving under a vacuum the first plate so as to face a second plate, and assembling the two plates with a specific peripheral sealing joint.

A method for assembling two parallel plates (1, 2) respectively forming the bottom and the face of a flat display screen including a degassing step of the plates (1, 2) and a vacuum burn-in step, the method including the following steps:
- subjecting a first plate (2) to a burn-in step by electronic bombardment,
- moving under a vacuum the first plate so as to face a second plate (1), and
- assembling the two plates (1, 2) with a specific peripheral sealing joint.
An equipment for assembling two parallel plates (1, 2) respectively constituting the bottom and the viewing surface of a flat display screen, including:
- at least one input airlock chamber (21) communicating with a vacuum chamber or a chamber in an inert atmosphere;
- at least one tunnel furnace (22) for thermal degassing of the plates (1, 2);
- means (23) for transferring under a vacuum a first plate (2) from the outside of the tunnel furnace toward an electronic bombardment burn-in section (25);
- means (23) for transferring under a vacuum the first plate (2) from the burn-in section (25) toward the sealing section (26);
- means for transferring under a vacuum a second plate (1) from a thermal processing section toward a sealing section (26);
- and
- at least one output airlock chamber for progressive transfer to atmosphere.
