Abstract
Disclosed are an alignment mask, a metal mask assembly, and a preparation method therefor. The alignment mask includes a mask body. The mask body includes: multiple alignment holes; and, separating parts surrounding at least some alignment holes and used for separating the areas at where the at least some alignment holes are located from other areas, where the separation parts include at least one semi-etched line.
Claims15
An align mask, comprising a mask body, wherein the mask body comprises:
- a plurality of align holes;
- and
- an isolation part, enclosing at least two of the align holes and isolating an area, where the at least two of the align holes are arranged, from other areas;
- wherein the isolation part comprises one or more half-etch lines;
- the mask body is strip-shaped,
- the mask body comprises:
- a retention area,
- two cut-out areas arranged at two ends of the retention area;
- and
- two cut-out half-etch lines respectively arranged at junctions between the two cut-out areas and the retention area;
- and
- the two cut-out half-etch lines extend in a first direction which is the same as an extending direction of short edges of the mask body.
A metal mask assembly, comprising a mask frame, a metal mask, an align mask, and a first welding spot part between the align mask and the mask frame;
- wherein the metal mask and the align mask are respectively welded onto the mask frame;
- the align mask comprises a body of a retention area;
- the body of the retention area comprises:
- a plurality of align holes, and
- a partitioning part, partitioning an area where at least two of the plurality of align holes are arranged from other areas;
- and
- the partitioning part comprises one or more cutting lines;
- the first welding spot part is arranged in the area where the at least two of the plurality of the align holes are arranged;
- the body of the retention area is strip-shaped;
- the plurality of align holes are closer to a first long edge of the body of the retention area than a second long edge of the body of the retention area, and are arrayed along the first long edge;
- the second long edge is a long edge opposite to the first long edge of the body of the retention area;
- the plurality of align holes comprise:
- two first align holes;
- and
- second align holes arranged between the two first align holes;
- wherein the two first align holes are respectively closer to two short edges of the body of the retention area than the second align holes;
- each of the short edges is provided with a first part, and a projection of one of the first align holes is closer to the each short edge than the second align holes, on the each short edge is arranged in the first part;
- and
- the first long edge is provided with two second parts corresponding to the two first align holes respectively, and a projection of each of the two first align holes, on the first long edge, is arranged in a corresponding second part.
A metal mask assembly, comprising a mask frame, a metal mask, an align mask, and a first welding spot part between the align mask and the mask frame;
- wherein the metal mask and the align mask are respectively welded onto the mask frame;
- the align mask comprises a body of a retention area;
- the body of the retention area comprises:
- a plurality of align holes, and
- a partitioning part, partitioning an area where at least two of the plurality of align holes are arranged from other areas;
- and
- the partitioning part comprises one or more cutting lines;
- the first welding spot part is arranged in the area where the at least two of the plurality of the align holes are arranged;
- the body of the retention area is strip-shaped;
- the plurality of align holes is closer to a first long edge of the body of the retention area than a second long edge of the body of the retention area and are arrayed along the first long edge;
- the second long edge is a long edge opposite to the first long edge of the body of the retention area;
- short edges of the body of the retention area are provided with first parts respectively;
- and projections of the plurality of align holes, on the short edges, are arranged in the first parts;
- the body of the retention area further comprises at least two test openings, the at least two test openings are closer to the second long edge of the body of the retention area than the first long edge of the body of the retention area and are arrayed along the second long edge;
- the partitioning part comprises a fourth cutting line arranged on one sides, away from the first long edge, of the plurality of align holes;
- and the fourth cutting line extends in a second direction which is the same as an extending direction of long edges of the body of the retention area;
- and
- the first parts of the two short edges, the first long edge and the fourth cutting line are connected end to end to form a loop around the plurality of align holes.
