Abstract
A tension mask assembly for a color cathode ray tube includes a tension mask including at least two divided portions, each having a plurality of strips separated a predetermined distance from each other for forming slots, and each having a plurality of bridges for connecting the strips and defining slots, and a frame including first and second support members for supporting both end portions of the divided portions so that tension is applied to the strips of the divided portions and at least one pair of elastic members for supporting the first and second support members.
Claims27
A tension mask assembly for a color cathode ray tube, comprising:
- a tension mask including at least two divided portions, each of said portions having a plurality of first strips separated a predetermined distance from each other by first slots, and each of said portions having a plurality of first bridges for connecting said first strips to each other and for defining said first slots;
- and
- a frame including first and second support members supporting end regions of said portions, and including at least one pair of elastic members to support said first and second support members and to apply tension to said first strips of said portions.
An apparatus, comprising:
- a tension mask including at least two divided portions, each one of said portions having a plurality of first strips separated a predetermined distance from each other by first slots, and each of said portions having a plurality of first bridges for connecting said first strips to each other and for defining said first slots;
- and
- a frame including first and second support members supporting end regions of said divided portions, and including at least one pair of elastic members to support said first and second support members and to apply tension to said first strips of said portions;
- adjacent divided portions selected from among said at least two divided portions partly overlapping each other at an overlapping portion, with a frictional force being formed at said overlapping portion.
1 more element
A method, comprising:
- emitting electron beams from an electron gun toward a tension mask assembly;
- passing said electron beams through said tension mask assembly at locations corresponding to first and second slots formed by said tension mask assembly;
- blocking said electron beams from passing through said tension mask assembly at locations corresponding to first and second strips formed by said tension mask assembly;
- blocking said electron beams from passing through said tension mask assembly at locations corresponding to first and second bridges formed by said tension mask assembly, said tension mask assembly having at least two divided portions, each one of said at least two divided portions having a plurality of said first strips separated a predetermined distance from each other by said first slots, and each of said divided portions having a plurality of said first bridges for connecting said first strips to each other and for defining said first slots, said tension mask assembly having a frame including first and second support members supporting end regions of said divided portions, and including at least one pair of elastic members to support said first and second support members and to apply tension at least to said first strips of said divided portions, each of said divided portions having at least one edge region, said edge regions of adjacent ones of said divided portions overlapping each other and being connected with each other at an overlapping portion, said overlapping edge regions forming said second slots and said second strips at said overlapping portion, said first strips having same shape as said second strips, said first slots having same shape as said second slots;
- and
- forming a frictional force between said adjacent ones of said divided portions, at said overlapping portion where said edge regions of said adjacent ones of said divided portions overlap each other.
