Abstract
When manufacturing a vacuum enclosure of an image display unit, degassing is performed by baking a back-side substrate provided with a plurality of strip-like slender spacer in a standing state. In this time, radiant heat is applied to the upper side of the spacer, to prevent the radiant heat reaching the side of the spacer, and to prevent an increase in a temperature difference between the spacer and back-side substrate.
Claims28
A method of manufacturing a vacuum enclosure of an image display unit having a plurality of reinforcing member arranged upright on a plate surface of a pair of opposed substrates,
- wherein the method is an image display unit manufacturing method, characterized by a step of controlling a temperature of the reinforcing member so as to adjust a temperature of the reinforcing member close to a temperature of the substrate, in a heat treatment process to heat and cool the substrate provided with the reinforcing member.
An apparatus for manufacturing a vacuum enclosure of an image display unit having a plurality of reinforcing member arranged upright on a plate surface of a pair of opposed substrates,
- wherein the apparatus is an image display unit manufacturing apparatus comprising:
- a heat treatment means for heating and cooling the substrate provided with the reinforcing member;
- and
- a control means for controlling a temperature of the reinforcing member to close to a temperature of the substrate, when heating and cooling by the heat treatment means.
