Abstract: A laser processing apparatus includes: a laser generator that generates a laser beam, a diffractive optical element that divides the laser beam generated by the laser generator into a plurality of sub-laser beams, and a beam gap adjustor that adjusts a gap between neighboring ones of the plurality of sub-laser beams. Therefore, by installing a diffractive optical element that divides a laser beam that is generated by the laser generator into the plurality of sub-laser beams and a beam gap adjustor to adjust a gap between a plurality of sub-laser beams, the laser processing apparatus can form a processing pattern of various resolutions in a shadow mask while improving a processing speed of the shadow mask.

Abstract: A mask substrate that includes a first area and a second area surrounding the first area is provided. Then, a laser beam is irradiated on the mask substrate to at least partly remove a material of the second area. After that, a physical force is applied to the mask substrate to separate the first area from the mask substrate thereby forming an opening through the mask substrate.

Abstract: A manufacturing method of a metal mask including a plurality of pattern openings includes forming a first depression portion by radiating a first laser beam focused on a plane beyond a subject under processing, and then forming the plurality of pattern openings at a bottom part of the first depression portion by radiating a second laser beam focused on the bottom part of the first depression portion. Because the energy of the second laser beam is less than the first laser beam, manufacturing time of the mask is reduced while the sidewalls of the pattern opening are smooth and may be inclined, to allow for a better deposition of organic emission material onto a large display.
Abstract translation: 包括多个图形开口的金属掩模的制造方法包括：通过将聚焦在超过加工对象的平面上的第一激光束照射形成第一凹陷部分，然后在第一凹部的底部形成多个图案孔 通过照射聚焦在第一凹陷部分的底部上的第二激光束来抑制凹陷部分。 因为第二激光束的能量小于第一激光束，所以掩模的制造时间减小，而图案开口的侧壁是平滑的并且可以倾斜，以便有机发射材料更好地沉积到大的 显示。

Abstract: A sheet cutting apparatus and a sheet cutting method using the same are disclosed. In one aspect, the sheet cutting apparatus includes a holder for rotatably supporting a sheet roll, a lamination unit for pulling and unwinding a front end of the sheet unwound from the sheet roll, a table on which the sheet unwound by the lamination parts is attached, and a tension unit for giving tension to the sheet attached on the table. Since the sheet cutting apparatus may cut the sheet consistently and stably, product quality and production efficiency should increase.

Abstract: A metal sheet holding device for manufacturing a pattern mask used in manufacturing processes of a flat panel displays include a first holder and second holder. The first holder includes an adhesive layer contacting edge portions of a metal sheet, and a first frame supporting the metal sheet using the adhesive layer. The second holder includes a second frame below the first frame, a supported plate positioned at the center of the second frame, and an adhered unit positioned between the central portion of a metal sheet and the supported plate. The adhered unit generates an electrostatic force or a magnetic force to hold the central portion of the metal sheet.

Abstract: A laser processing apparatus includes a laser generator for generating laser beams, a diffraction optic element for dividing the laser beam generated by the laser generator into a plurality of sub-laser beams, and a beam number controller for controlling the number of the plurality of sub-laser beams. Accordingly, the diffractive optic element that splits a laser beam generated by the laser beam generator into a plurality of sub-laser beams and the beam number controller that controls the number of sub-laser beams are provided so that the processing speed of a processing target can be improved and, at the same time, the number of laser beams can be promptly controlled, thereby promptly forming various patterns of the processing target.
