Method of manufacturing mask assembly for thin film deposition

摘要

A method of manufacturing a mask assembly for thin film deposition includes: positioning a division mask on a mask frame, wherein the division mask has a length in a first direction that is greater than a width in a second direction perpendicular to the first direction; and spot welding opposing ends of the division mask along the first direction to the mask frame, wherein the spot welding comprises: forming first welding points in a first zigzag pattern starting from a peripheral portion along the second direction of the division mask toward a central portion along the second direction of the division mask; and forming second welding points between the first welding points.

1. A method of manufacturing a mask assembly for thin film deposition, comprising:
positioning a division mask on a mask frame, wherein the division mask has a length in a first direction that is greater than a width in a second direction perpendicular to the first direction; and spot welding opposing ends of the division mask along the first direction to the mask frame, wherein the spot welding comprises:
forming first welding points in a first zigzag pattern, by starting the first zigzag pattern, simultaneously or sequentially, from opposite sides of the division mask and extending the first zigzag pattern along the second direction of the division mask toward a central portion of the division mask; andforming second welding points between the first welding points by forming the second welding points in a second zigzag pattern to extend along the second direction and cross a formation path of the first welding points.
