| Abstract: | In order to improve the quality of the color picture tube and reduce the influence of geomagnetic field on the color picture tube, usually the color picture tube is pre-adjusted to meet the demand by using gauss-room to stimulate geomagnetic field of market area during the manufacture of the color picture tube. A kind of new equipment that economically and effectively shields the influence of geomagnetic field is put forward through studing the concerned disciplines of electron optics, electromagnetic shielding theory and magnetic material, etc. An advanced tester of the color picture tube is used to compare the shielding result of the new equipment with that of current shielding equipment in the same condition. It is proved that this new equipment is more effective and practicable. This new equipment can restrain the influence of geomagnetic field and increase the geomagnetic tolerance of the color picture tube. |
| Keywords: | geomagnetic field color picture tube shield misregister geomagnetic tolerance |
