The demands of modern television reception have necessitated the use of the “all-magnetic” cathode ray tube in receivers. The ion-burn screen blemish associated with the all-magnetic tube can be prevented by depositing a thin layer of aluminium on the back of the phosphor coating. The characteristics required by such a layer and methods of preparing it are described in this paper. Further advantages, of the aluminium backed screen, among them the prevention of screen voltage saturation effects and improved brightness and contrast, are described and explained.
