| 摘要 |
The present invention is directed to a color cathode ray tube comprising an evacuated envelope with a tube axis including a face panel having an inside wall with stud pins, a funnel connected to the panel and a neck extending from the funnel; a shadow mask assembly including a shadow mask facing the face panel, and a mask frame for supporting the shadow mask; a plurality of support members for suspending the shadow mask assembly to the stud pins, each of the support members comprising a first arm portion coupled to the study pin, a second arm portion connected to the mask frame and a folded portion connecting the first and second arm portions with each other; and a control member for controlling a deformation of each the support members, the control member connecting the folded portion to the mask frame, whereby the rotation of the shadow mask assembly caused by a deformation of the support member by an irregular inside wall of the face panel or by a thermal expansion of the shadow mask assembly can be prevented.
