摘要
The present invention relates to a method for pre-stressing the CRT tension mask 24 to induce creep. The method includes the steps of applying a suitable force to the mask material to induce stress therein, heating the mask material to an ultimate temperature, for a sufficient time, while under stress, to induce creep, and cooling the material.
