Abstract
A mask frame assembly including a frame having an opening, a mask having a first end and a second end supported on the frame, and a first member disposed between the first end of the mask and the frame, the first member including a material having a coefficient of thermal expansion greater than that of the mask. A method of manufacturing a display apparatus using the mask frame assembly also is disclosed.
Claims20
A mask frame assembly comprising:
- a frame having an opening;
- a mask having a first end and a second end supported on the frame;
- and
- a first member disposed between the first end of the mask and the frame, the first member comprising a material having a coefficient of thermal expansion greater than that of the mask.

A method of manufacturing a display apparatus, the method comprising the steps of:
- providing a mask frame assembly having a frame and at least one opening, a mask having an end supported on the frame, and a member disposed between the end of the mask and the frame comprising a material having a coefficient of thermal expansion greater than that of the mask;
- coupling the mask to the member by a coupling;
- applying a tensile force to the mask and through the coupling by heating the mask frame assembly such that the mask expands a first distance and the member expands a second distance greater than the first distance;
- and
- depositing a deposition material through the at least one opening to a display region of a substrate.
