摘要
利用光学折射原理推导了平面彩色显像管显示屏内表面与其虚像的关系 ,并进行了数值计算模拟 ,得到了显示屏内表面的优化曲率半径。采用此设计方法制作彩色显像管 ,既能得到失真较小的显示图像 ,又能使显示屏内表面曲率半径较大 ,提高显示屏抵抗大气压力的能力。
The relationship between the inner surface of the flat face cathode ray tube(CRT)and the virtual image was derived and simulated on the basis of optical reflection,and the radius of the inner surface curvature of the tube was optimized.The advantages of the CRT with optimized inner surface geometry include less virtual image distortion and higher strength against air pressure because of larger radius of the inner surface curvature.
