【Abstract】 A multi-gun color CRT can make the realization of large screen thin CRT into possible.The key of this proposal is to determine the structure of the glass bulb and calculate its strength.The parameterized methods are used to design the glass bulb structure,such as surface form,curavture variety.The design efficiency of glass bulb is greatly improved.Our computer simulation results show that the structure of the glass bulb designed for a 42-inch nine-gun color CRT can satisfy strength requirements as well as the surface form.更多还原
