Abstract
Apparatus for manufacturing cathode ray tube display screens having a face plate with an affixed layer of photosensitive material and an apertured mask spaced from the photosensitive layer and attached to the faceplate includes an exposure chamber having a source of actinic energy spaced from the faceplate and a shutter intermediate the actinic energy source and the faceplate with the shutter movable in one given direction to initiate and to interrupt impingement of the faceplate by light rays from the actinic energy source. In a process for fabricating cathode ray tube display screens, a faceplate having a layer of photosensitive material on the inner surface and an apertured mask spaced from the photosensitive material and affixed to the faceplate is disposed on and supported by an exposure chamber having a source of actinic energy spaced from the faceplate with a shutter intermediate the energy source and the faceplate and the shutter movable in a given direction to cause light rays from the energy source to impinge the faceplate and movable in the same given direction to interrupt impingement of the faceplate by light rays from the energy source.
