ABSTRACT:
A cathode ray tube subjected to an antistatic treatment and a method of making the same. A conductive surface of a panel of a bulb body is grounded through a metal reinforcement serving as a reinforcement for maintaining the bulb's inward bursting resisting properties to instantaneously leaking any electrified charge, thereby providing the antistatic cathode ray tube which is free from the effect of air-conditioned humidities. Thus, there is the effect of preventing the occurrence of erroneous operations of the cathode ray tube and peripheral units and adverse effects on the human body, e.g., electric shock due to the charged static electricity on the panel surface, and there is another effect that the implosion protective adhesive glass tape or the member interposed between the conductive coating and the metal reinforcement is equivalent to lead wires thus eliminating the use of lead wires and thereby eliminating the provisions of complicated connections to the panel surface.
