[0011] The above-mentioned metal mask plate used in the preparation of a display panel, wherein the jig is threadedly connected to the receiving groove.

[0012] In the above-mentioned metal mask plate used in the preparation of a display panel, the receiving groove is a hexagonal groove, and the fixture is threadedly connected to the receiving groove via a hexagonal screw.

[0013] The above-mentioned metal mask plate used in the preparation of display panels, wherein, further comprises: a mesh stretching area and a metal frame, wherein the mesh stretching area and the alignment area are both arranged on the metal frame.

[0014] The above-mentioned metal mask plate used in the preparation of a display panel, wherein the alignment area is located on both sides of the stretching area.

[0015] The above-mentioned metal mask plate used in the preparation of the display panel further includes: a vapor deposition area, on which a vapor deposition pattern is provided.

[0016] The above-mentioned metal mask plate used in the preparation of a display panel, wherein the distance between the alignment area and the display panel is 20-30 microns.

[0017] Compared with the prior art, the above technical solution has the following positive effects:

[0018] The utility model provides a receiving groove, in which the jig can be detachably installed, and the positioning is accurate. During the cleaning process, the color mixing caused by abnormal positioning due to wear can be prevented, thereby saving time, labor and cost. BRIEF DESCRIPTION OF THE DRAWINGS
