BULB FOR CATHODE RAY TUBE

摘要

PURPOSE: A bulb for cathode ray tube is provided to apply uniformly a fluorescent layer by changing an inside structure of a panel. CONSTITUTION: A bulb for cathode ray tube comprises a panel(21), a funnel(22), and a deflection yoke(27). The panel(21) has uniform thickness between its front portion and its rear portion. A fluorescent layer(23) and an aluminum layer(24) are applied sequentially on the rear portion. The funnel(22) is combined with the panel(21). An electron gun(26) is installed at a neck portion of the bulb. The electron gun(26) emits an electron beam to the fluorescent layer(23) of the panel(21). The deflection yoke(27) is loaded on an outer circumference of the funnel(22) in order to deflect the electron beam to each portion of the fluorescent layer(23).
