  • Method for preparing a viewing-screen structure for a CRT having temperature-compensated mask-mounting means, including cooling mask during exposure
    Patent number: 3970456
    Abstract: In a direct photographic process for preparing a viewing-screen structure for a shadow-mask-type CRT having temperature-compensated mask-mounting means, an inner surface of the panel is coated with a layer of light-hardenable material and then heated above 50.degree.C to dry the layer. While the panel is above 40.degree.C, the layer is exposed to actinic light through the mask of the tube. The temperature-compensating-mounting means for the mask is cooled, as with streams of air, to adjust the spacing between the mask and the inner surface of the panel and to prevent the mask from being twisted on the mounting means. Also the mask may be cooled to prevent doming of the mask.
