An exposure apparatus for colour cathode ray tubes.

摘要

An exposure apparatus for the manufacture of colour cathode ray tubes having a single faceplate with a phosphor screen on an inner surface thereof comprises light source (42) for emitting ultraviolet light, exposure device including a base (51) for supporting the faceplate with a photosensitive layer (52) having a plurality of secondary light source (47) emitting exposure light for exposing corresponding sub-regions and moving device (50) for shifting the position of the secondary light sources (47), and light distribution device (57) for distributing the ultraviolet light emitted from the light source device (42) substantially equally to the secondary light sources (47).
