摘要:
A method of manufacturing a control grid used in a fluorescent display tube is disclosed. The grid is produced by preparing a fine wire net, placing the wire net upon a metal frame member, and irradiating laser beams to the contact portions of the wire net and frame to weld the wire net and the frame.
