Abstract
A flat tension mask frame assembly is provided, including a frame and a tension mask. The frame has first and second support members which are separated from each other by a predetermined distance, and have fixing portions and flange portions which are bent inwardly from the fixing portions and become narrower from the center portion to both ends of the flange portions, and at least two elastic members fixed at both ends to the first and second support members for supporting the support members. The tension mask has facing edges which are fixed to the fixing portions of each of the first and second support members in a state where a tensile stress has been applied to the facing edges.
Claims11
A tension mask-frame assembly, comprising:
- a frame comprising
- two support members spaced from each other, each of said support members comprising a fixing portion and a flange portion;
- and
- at least two elastic members each having opposite end portions fixed to the support members for supporting the support members;
- and
- a tension mask having opposite edges fixed to the fixing portions of the support members, respectively, in a state when the tension mask is being stretched in a stretching direction by a tensile stress tending to move the opposite edges of the tension mask away from each other;
- wherein the flange portion of each of the support members has a width, as measure in the stretching direction, decreasing from a central region of said flange portion toward opposite ends thereof, thereby limiting a capability of a central region of the frame, which corresponds to the central regions of the flange portions, to deform in the stretching direction.
A tension mask-frame assembly, comprising:
- a frame comprising
- two support members spaced from each other, each of said support members comprising a fixing portion and a flange portion extending at a predetermined angle from the fixing portion;
- and
- at least two elastic members each having opposite end portions fixed to the support members for supporting the support members;
- and
- a tension mask having opposite edges fixed to the fixing portions of the support members in a state when the tension mask is being stretched in a stretching direction by a tensile stress tending to move the opposite edges of the tension mask away from each other;
- wherein each of the support members has a deformability in the stretching direction which increases from a central region of said support member toward opposite ends thereof;
- and
- wherein the fixing portions of each of the support members is curved away from the other support member in the stretching direction.
