In specific implementation, the Mask provided by the embodiment of the invention can be based on the Mask of the Open Mask, and the Open Mask is designed to be an AA area full-empty design, so that the light-emitting layer can be uniformly and effectively evaporated in the AA area to realize the light emission of the AA area. Open Mask is mainly used in the production of white light organic electroluminescent devices (WOLEDs) of Active-matrix organic light emitting diodes (AMOLED). The technology is mainly used for manufacturing and producing large-size panels, the size of an Open Mask is large, and common layers such as a hole injection layer, a hole transport layer and an organic electroluminescent layer are manufactured in WOLED technology.
In particular, as shown in fig. 2, each first connection portion 3 includes connection bars 32 and connection blocks 31 alternately arranged at intervals, wherein the width of the connection block 31 is larger than the width of the connection bar 32 in a direction perpendicular to the direction in which the first connection portion 3 extends (i.e., in a direction along AB as in fig. 2); the plurality of first connecting portions 3 are radially distributed around the shielding portion 2. Further, the connection bars 32 and the connection blocks 31 may be distributed symmetrically with respect to the shielding portion 2. In the embodiment of the present invention, each first connection portion 3 includes the connection bars 32 and the connection blocks 31 alternately arranged at intervals, that is, the first connection portion 3 includes the connection bars 32, so that the first connection portion 3 can be made as thin and narrow as possible, so as to avoid affecting the manufacture of the light emitting layer in the area other than the preset area of the display area, and the connection firmness of the first connection portion can be ensured by including the connection blocks 31 in the first connection portion 3.
In specific implementation, referring to fig. 3, the mask plate further includes a plurality of annular second connection portions 4 surrounding the shielding portion 2 in sequence, where the second connection portions 4 are disposed to intersect with the first connection portions 3, so as to form a spider-web structure. In the embodiment of the invention, each first connecting part 3 comprises connecting strips 32 and connecting blocks 31 which are alternately arranged at intervals, the mask plate further comprises a plurality of annular second connecting parts 4 which sequentially encircle the shielding parts 2, the second connecting parts 4 and the first connecting parts 3 are arranged in a crossing way to form a spider-like net structure, and the connecting strips 32 and the connecting blocks 31 are symmetrically distributed in the center with the shielding parts 2 as the center, so that the uniformity control of the net stretching force can be facilitated and the position precision of the shielding parts can be ensured when the mask plate is manufactured through net stretching.
In a specific implementation, the shielding portion 2, the first connecting portion 3, and the second connecting portion 4 are all made of the same material as the frame 1. In the embodiment of the invention, the shielding part, the first connecting part and the second connecting part are all made of the same material as the frame, and the mask plate can be manufactured by a one-time etching process, so that the mask plate is simpler to manufacture.

In a specific implementation, the distance between the two points furthest from the shielding part 2 is less than or equal to 2 mm. For example, when the shielding portion is circular, the diameter of the circular shape is less than or equal to 2 mm. That is, since the shielding portion 2 of the mask plate in the embodiment of the present invention is mainly used for setting components such as a camera on the display panel, and since the components are smaller, the size of the shielding portion 2 should not be too large, so as to reduce the influence on the light-emitting layer of the organic light-emitting display panel.
