摘要:
A process for manufacturing a color picture tube capable of minimizing the thermal deformation of the shadow mask is disclosed. A getter is filled with a Ba material, a high or low vaporizing material having a different vaporizing temperature compared with that of the Ba material, and the getter is installed within the color picture tube. The getter is heated by a microwave heating device, so that the Ba material is vaporized so that the vacuum level of the color picture tube is raised. The high or low vaporizing material is vaporized and coated onto an aluminum film of a panel or on the surface of the shadow mask. This vaporizing material layer coated on the aluminum film or on the surface of the shadow mask absorbs the heat generated by the shadow mask, so that the thermal expansion and the thermal deformation of the shadow mask is inhibited, thereby improving the colorimetric purity of the phosphor screen and extending the life expectancy of the color picture tube.
