Abstract
A post-mask-deflection color cathode ray tube is disclosed that has a strip-type tension foil shadow mask in the form of two intercalated combs providing mutually insulated first and second arrays of strips. Each of the arrays is adapted to receive a different electrical potential effective to cause electron beams passing therethrough to be deflected by the electrical fields created between the strips. A method of manufacturing is also disclosed.
