Abstract
A mask frame assembly for thin film deposition, the mask frame assembly including a frame having an opening; a plurality of masks having deposition patterns, the masks being fixed to the frame such that the deposition patterns extend over the opening; and a balance stick being fixed to the frame such that the balance stick is between two of the plurality of masks, the balance stick made from an elastically tensile material.
Claims5
A mask frame assembly for thin film deposition, the mask frame assembly comprising:
- a frame having an opening and a plurality of grooves;
- a plurality of masks having deposition patterns, the masks being spaced from each other and fixed to the frame such that the deposition patterns extend over the opening, wherein a longitudinal axis of each of the masks extends in a first direction;
- and
- a balance stick being fixed to one of the grooves on the frame, wherein the balance stick is between two of the plurality of masks such that a longitudinal axis of the balance stick is substantially parallel to the longitudinal axis of each of the masks, the balance stick comprising an elastic material, wherein a thickness of the balance stick is greater than a thickness of each of the masks and wherein an outwardly-facing surface of each balance stick is substantially flush with an outwardly-facing surface of each of the masks.
