A mask manufacturing equipment includes a first stage on which a mask frame is disposed, the mask frame including cell openings arranged in a first direction and a second direction intersecting the first direction, a transfer module that places cell masks on the mask frame to respectively overlap the cell openings of the mask frame and the cell masks, a camera module that photographs the cell masks, a first processing module that irradiates a first laser beam between a border portion corresponding to a portion of the mask frame adjacent to an N-th cell opening and a first edge area of an N-th cell mask disposed on the border portion, and a second processing module that irradiates a second laser beam to a boundary area between the first edge area and a second edge area extending from the first edge area.

Mask manufacturing equipment and method of manufacturing mask using the same

A mask assembly includes a mask frame through which a plurality of openings is defined and a plurality of cell masks disposed to respectively correspond to the cell openings. Each of the cell masks includes a mask main body substantially parallel to a plane defined by a first direction and a second direction crossing the first direction, where a plurality of holes is defined through the mask main body, a bonding portion disposed along an edge of the mask main body, and a tensile portion extending from the bonding portion and disposed spaced apart from the mask main body. The tensile portion includes first tensile portions spaced apart from each other in the first direction and disposed at opposite sides of the mask main body and second tensile portions spaced apart from each other in the second direction and disposed at opposite sides of the mask main body.

Mask assembly, mask manufactured using the same, and method of manufacturing display panel

Provided is a mask including a mask frame including a base part in which cell openings are defined, and a coating part surrounding edges of the cell openings, covering at least a portion of an upper surface of the base part, and including a materials that is different from that of the base part, and unit masks on the mask frame, respectively corresponding to the cell openings, including a material that is different from that of the coating part, and in which openings are defined.

Mask and method of manufacturing the same

A method for manufacturing a mask includes providing, on a stage, a mask frame in which a plurality of cell openings is defined; providing each of the cell openings with a cell mask material in which a second area and a plurality of first areas are defined, where the second area is disposed around each of the first areas; emitting a laser beam to the second area to harden the second area; and removing the first areas, thereby forming a plurality of cell masks disposed in the cell openings, respectively.

Mask and method for manufacturing mask

An apparatus and a method for manufacturing a mask assembly and a method of manufacturing a display device are provided. The apparatus may include: a tensioning part configured to be spaced apart from a mask frame comprising at least one opening, the tensioning part configured to tension a mask sheet in at least one of a first direction and a second direction, the mask sheet comprising a cell area corresponding to the at least one opening, and a dummy portion arranged outside the cell area; a pressing part configured to correspond to the dummy portion and press the dummy portion in a third direction intersecting a plane in which the first direction and the second direction extend; and a header configured to irradiate a laser beam toward the mask sheet to fix the mask sheet to the mask frame.

Method and apparatus for manufacturing mask assembly and method of manufacturing display device

A mask chuck may include a base plate including a central region and an edge region surrounding the central region, a head part including a first surface connected to the edge region of the base plate and configured to move on the edge region to be close to the central region or away from the central region, and a pad part disposed on a second surface of the head part opposite to the first surface of the head part. The edge region may include a first edge region extending in a first direction, a second edge region extending in the first direction and spaced apart from the first edge region in a second direction crossing the first direction, a third edge region extending in the second direction, and a fourth edge region extending in the second direction and spaced apart from the third edge region in the first direction.

Mask chuck and mask manufacturing apparatus including same

A mask frame assembly manufactured via an extension-welding process on a stage, the mask frame assembly includes: a mask frame disposed on a stage, the mask frame including a first frame and a second frame having a first length, and a third frame and a fourth frame having a second length, the second length less than the first length. The mask frame assembly also includes a mask having respective ends welded and combined onto the first frame and the second frame. The first frame and the second frame include a slot disposed toward the stage, and at least portions of the first frame and the second frame corresponding to the slot are not in contact with the stage. The third frame and the fourth frame and the stage are in contact with the stage.
