Abstract
A method of manufacturing a color display tube comprising an envelope having a display window and a color selection electrode and suspension means for suspending the color selection electrode, which four suspension means each contain a member which is fused into the envelope. In the method these members are heated by means of a laser. The members may be provided with bores on which the laser beam is incident, the surfaces of which may be blackened to increase heat absorption. The method is more energy efficient and less cumbersome than the prior method which relied upon coils to heat the members by induction of eddy currents.
