A repairing method of a mask assembly includes providing a mask assembly including a frame, an open mask including a first opening disposed on an upper surface of the frame, and a first unit mask including a plurality of first deposition openings to overlap the first opening in a plan view and disposed on an upper surface of the open mask, first cutting the open mask at an outside of the first unit mask such that a second opening having a size greater than a size of the first opening is defined, and connecting the second unit mask including a plurality of second deposition openings corresponding to the plurality of first deposition openings to the first cut open mask.

A deposition mask group includes a first deposition mask having two or more first through holes arranged along two different directions, a second deposition mask having two or more second through holes arranged along two different directions and a third deposition mask having two or more third through holes. The first through hole and the second through hole or the third through hole partly overlap when the first deposition mask, the second deposition mask and the third deposition mask are overlapped.

Provided is a mask which includes a mask body having a plurality of through hole portions and including a polymer film and a plurality of magnetic particles dispersed in the polymer film, and a polymer coating layer disposed on an outer surface of the mask body. Accordingly, the time and cost of manufacturing a mask are reduced and the precision of a deposition process is improved as well, so that the manufacturing yield of a display panel using the mask is improved and a display panel manufactured using the same has improved reliability.

Provided by the present disclosure are a mask assembly and a manufacturing method thereof. In the mask assembly, a plurality of connecting posts are arranged at intervals on an outer periphery of a body of a metal plate, and a plurality of grooves matched with the connecting posts are arranged on a metal frame.

The present invention relates to an electromagnetically transparent metallic-luster member including a base and a metal layer formed over the base, wherein the metal layer includes a plurality of portions which are at least partly discontinuous and separate from each other, the metal layer includes a portion including aluminum element and a portion including indium element, the portion including indium element localizes in the metal layer, and a volume content (vol %) of the portion including indium element in the metal layer is 5-40 vol %.

A deposition mask includes: a first surface and a second surface, in which a plurality of through-holes are formed; a pair of long side surfaces connected to the first and second surfaces, and defining a profile of the deposition mask in a longitudinal direction of the deposition mask; and a pair of short side surfaces connected to the first and second surfaces, and defining a profile of the deposition mask in a width direction of the deposition mask. The long side surface includes a first portion that is recessed inside and includes a first end portion positioned along the first surface, and a second end portion positioned along the second surface and positioned inside the first end portion. The through-hole includes a first recess formed on the first surface, and a second recess formed on the second surface and connected to the first recess through a hole connection portion.

A method for printing uses at least one ink. The method includes: a step of focusing a laser beam so as to generate a cavity in an ink film; a step of forming at least one ink droplet from a free surface of the ink film; and a step of depositing the droplet onto a depositing surface of a receiving substrate positioned at a given distance from the film. The laser beam is oriented in the direction opposite the gravitational force. The free surface of the film is oriented upwards towards the depositing surface placed above the ink film.

A screen tensioning device used during fabrication of mask plate includes a screen tensioning machine base and a jig disposed on the screen tensioning machine base, and further includes a magnetic plate positioned above the screen tensioning machine base, and an upwardly-directed vertical suction force acting on the screen of the mask plate to be fabricated by the magnetic plate is equal to an upwardly-directed vertical suction force acting on the screen of the mask plate by a magnetic field system in a vacuum evaporation chamber during evaporation. A screen tensioning method used during fabrication of mask plate is also provided.

Embodiments of the present disclosure relate to forming multi-depth films for the fabrication of optical devices. One embodiment includes disposing a base layer of a device material on a surface of a substrate. One or more mandrels of the device material are disposed on the base layer. The disposing the one or more mandrels includes positioning a mask over of the base layer. The device material is deposited with the mask positioned over the base layer to form an optical device having the base layer with a base layer depth and the one or more mandrels having a first mandrel depth and a second mandrel depth.
