BAND COUPLING STRUCTURE FOR FLAT CATHODE RAY TUBE

摘要

PURPOSE: A band coupling structure is provided to reduce the thickness of panel and manufacturing costs by recovering the displacement of the panel during ventilation process, through the use of a tension force. CONSTITUTION: A flat cathode ray tube comprises a panel(102) which is pressured by an atmospheric pressure since the cathode ray tube is vacuumed; and a funnel(103) having a linear section(103a) formed at the top of the funnel so as to mount a band(110), wherein the linear section is vertical to the panel. The band to be coupled onto the top of the funnel has a tension force of 600kgf to 3000kgf. The linear section is formed into a length of 16mm or longer.
