ABSTRACT:
A color television display tube having color selection means connected electrically by at least one metal contact spring to a resistive layer provided on the inner surface of the envelope of the tube. A low resistance contact face is applied on the resistive layer between the spring and the layer to reduce the contact resistance therebetween, thereby reducing undesirable interference radiation transmitted by the tube.
