Abstract

The present invention relates to a laser processing method and a method for manufacturing a mask assembly, the laser processing method comprising: arranging a plurality of guide lines on a workpiece in a first axis direction of a plate-shaped workpiece, wherein the plurality of guide lines include curves; arranging a plurality of unit processing regions disposed on the workpiece to be spaced apartfrom each other along the plurality of guiding lines; and illuminating the plurality of unit processing regions while moving the irradiation position of the laser beam using the laser beam.

Description

technical field [0001] The present invention relates to a laser processing method and a method of manufacturing a mask assembly, and more particularly, to a laser processing method and a method of manufacturing a mask assembly that compensate for shape changes when stretching a workpiece. Background technique [0002] When manufacturing an active matrix organic light-emitting diode (AMOLED), a vacuum deposition process is performed to deposit several layers of organic material, and should be deposited for each of the RGB (red, green and blue) pixels Different organic materials. Here, a fine metal mask (FMM) is used as a screen mask so that the organic material is only deposited on desired pixels and not on other regions. [0003] Generally, a fine metal mask assembly is fabricated such that each of a plurality of mask bars fabricated as separate masks is stretched and fixed to a frame by welding or the like. When a masking rod is stretched to secure said masking rod to the...
