Patent ID: 7005786

Claim:
A tension mask frame assembly for a color CRT comprising: a frame comprising: first and second support members separated a predetermined distance from each other, and first and second elastic members installed between the first and second support members to support the first and second support members, each of the first and second elastic members having a connection portion and support portions separated by and connected to corresponding opposite sides of the connection portion, each of the support portions being fixed to a corresponding one of the first and second support members; a mask having electron beam passing holes formed therein and installed such that tension is applied by the first and second support members; a correction unit connecting the first and second support members or connecting the support portions at a location of the first and second elastic members between the connection portion and said mask, said correction unit to correct a mis-landing of an electron beam due to a thermal expansion of said mask and said frame by changing a radius of curvature in a tube axis direction of the first and second support members and said mask by a difference in the thermal expansion amount between the first and second elastic members and the first and second support members; and single-metal hook members selectively installed at the first and second support members and the first and second elastic members.
