ABSTRACT:
A method of exposing a photosensitive layer or a fluorescent slurry layer deposited on the inner surface of a panel in which a shadow mask frame assembly is installed and apparatus therefor, are provided. A shadow mask installed inside the panel is induction-heated to a predetermined temperature using an induction-heating coil to be sufficiently expanded, and then the photosensitive layer or the fluorescent slurry layer deposited inside the panel is exposed via electron beam passing holes formed in the shadow mask. Therefore, the initial stabilization time for the CRT can be shortened.
