Abstract
A tension mask assembly for a color cathode-ray tube includes a tension mask including a plurality of strips separated a predetermined distance from each other to form slots, a plurality of bridges connecting the strips to section the slots, and a plurality of holes formed in each of short side portions of the tension mask, a frame including first and second support members supporting both long side portions of the tension mask to apply a tension force to the strips of the tension mask, and at least a pair of elastic members supporting the first and second support members, and a plurality of vibration attenuation units coupled to the holes formed at both short side portions of the tension mask to attenuate vibrations of the tension mask.

A tension mask assembly for a color cathode-ray tube, comprising:
- a tension mask including a plurality of strips separated a predetermined distance from each other to form slots, a plurality of bridges connecting the strips to section the slots, and a plurality of holes formed in each of short side portions of the tension mask;
- a frame including first and second support members supporting both long side portions of the tension mask to apply a tension force to the strips of the tension mask, and at least a pair of elastic members supporting the first and second support members;
- and
- a plurality of vibration attenuation units coupled to the holes formed at both short side portions of the tension mask to attenuate vibrations of the tension mask,
- with one end portion of one of the vibration attenuation units being bent so as not to be separated from a hole of the tension mask,
- with the one of the vibration attenuation units being firmly secured to the tension mask.
(Currently Amended) A tension mask assembly for a color cathode-ray tube, comprising:
- a tension mask;
- a frame supporting the tension mask;
- and
- a plurality of vibration attenuation units coupled to the tension mask through the holes formed at both short side portions of the tension mask to attenuate vibrations of the tension mask, at least one end portion of two vibration attenuation units being bent at an angle so as not to be separated from each of the holes of both short side portions of the tension mask.
