    摘要: In an exposure method for a picture tube, photoresists which are applied on an inner surface of a panel are exposed through a shadow mask to fix the photoresists on the inner surface of the pane. A position where light, which is emitted by an exposure light source and passes through an outermost slot of the shadow mask, becomes directly incident on the inner surface of the panel, and a position where light, which is emitted by an exposure light source at the same position as that of the first exposure light source or at a different position from that of the first exposure light source, passes through a slot inside the outermost slot of the shadow mask, is reflected by an outer surface of the panel, and returns, becomes incident on the inner surface of the panel are set to coincide with each other. An exposure apparatus for achieving this method is also disclosed.

    摘要: A color cathode ray tube (CRT) has a panel having a fluorescent film consisting of a number of groups of phosphors each radiating in a particular color. A shadow mask adjoins the fluorescent film and is formed with a number of apertures by etching. Electron guns are located at the side opposite to the fluorescent film with respect to the shadow mask, and emit electron beams for causing the phosphors to radiate. An insulating glass layer covers the edges of the apertures on the side of the shadow mask that faces the fluorescent film. The glass layer increases the mechanical strength of the shadow mask and enhances landing accuracy.
