Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] During the process of using the mask to form the encapsulation layer on the display substrate, the encapsulation material deposited on the mask will warp and cause the part of the mask in contact with it to warp, affecting the normal use of the mask. An embodiment of the present invention provides a mask. When the mask is used to form an encapsulation layer on a display substrate, the degree of warping of the mask is small, and the e...

Abstract

The invention provides a mask plate and a mask assembly, and belongs to the technical field of display. The mask plate comprises n opening areas and perimeter areas beside the n opening areas, whereinn>=1, and concave parts are arranged in the perimeter areas of the mask plate. By means of the mask plate, the problem that in a mask plate use process, the tilting degree of a packaging material which participates on the mask plate is large, so that the tilting degree of the mask plate is large, and effects on normal use of the mask plate are large is solved; the mask plate is used for producinga display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a mask plate and a mask component. Background technique [0002] With the development of science and technology, the application of the display panel is more and more extensive. The display panel includes a display substrate and an encapsulation layer. In the process of manufacturing the display panel, the encapsulation layer needs to be formed on the formed display substrate. [0003] In the process of forming the encapsulation layer on the display substrate, it is necessary to face the opening area of ​​the mask plate to the display area of ​​the display substrate, and deposit the encapsulation material on the display substrate from the side of the mask plate away from the display substrate, so as to cover the display area of ​​the display substrate. A layer of encapsulation material is formed inside. Moreover, during the process of depositing the encapsulation material, the ...
