COLOR PICTURE TUBE HAVING A LOW EXPANSION TENSION MASK. |
| 摘要 |
<p>A color picture tube (10) has a tension mask (24) attached to a support frame (50), wherein the mask is made from a material having a significantly lower coefficient of thermal expansion than the coefficient of thermal expansion of the material of the frame.
