| Abstract: | In this paper, some mechanics problems on the
design of CRT are discussed. These problems include the
FEM analysis of the thermal stress during the manufac-
turing process of the panel and of the thermal deformation
of the mask, and the investigation of the vibration and mi-
crophony effect of the mask. Furthermore, by a numerical
example, the effectiveness of this analysis is investigated. |
