Abstract

In this paper, we have studied the effect of electron reflection on shadow mask on which tungsten oxide film is coated and have studied the variation of beam mislanding with coating thickness in CRT. We found the method to be able to control coating thicknessed and optimum coating thickness of tungsten oxide film was 1∼2$\mu\textrm{m}$. Mislanding of electron beam was reduced about 20∼48% with increasing coating thickness in CRT
