Abstract: A method for processing color cathode ray tubes each having a color selection electrode consisting of a thin metal foil with a pattern of electron-transmissive apertures formed therein. The foil is stretched across the bulb of the tube and sealed directly thereto. According to this invention, such a tube may be exposed and screened without the necessity of resorting to a processing system which dictates the use of interchangeable masks.
Abstract translation: 一种处理彩色阴极射线管的方法，每个彩色阴极射线管均具有由形成有电子透射孔图案的薄金属箔构成的选色电极。 箔被拉伸穿过管的灯泡并直接密封在其上。 根据本发明，这种管可以被暴露和筛选，而不需要诉诸使用可互换掩模的处理系统。
