Abstract

The application discloses a mask plate assembly comprising a mask frame, a first mask plate and a second mask plate, a bearing surface is formed on the surface of one side of the mask frame, and the mask frame comprises a groove with an opening located in the bearing surface; the first mask plate comprises a plurality of first open holes and first shielding areas distributed around the first open holes, a plurality of extending ends are formed in the circumferential direction of the first mask plate, the extending ends are clamped in the grooves, and the bearing surface is exposed through the space between every two adjacent extending ends; and the second mask plate comprises a plurality of second open holes in one-to-one correspondence with the first open holes, second shielding areas distributed around the second open holes and an edge area fixed with the bearing surface. In the mask plate assembly provided by the invention, the first mask plate and the second mask plate are not overturned, so that the accuracy of the evaporation position is improved, and the evaporation quality is improved.

Description

technical field [0001] The present application belongs to the technical field of display devices, and in particular relates to a mask assembly. Background technique [0002] With the development of display technology, the current mobile phone screen has a tendency to develop towards medium and large sizes. In the manufacturing process of the display panel for mobile phone screens, it is necessary to re-layout the evaporated glass substrate to meet the new medium and large size requirements. The same typesetting change was made to the layout of the mask plate used to evaporate the glass substrate to be evaporated, but after the layout was changed, the magnetic strip in the evaporation machine appeared to be poorly adsorbed to the mask plate, which affected the evaporation. Plating quality. Contents of the invention [0003] An embodiment of the present application provides a mask assembly, in which neither the first mask nor the second mask is reversed, thereby improving t...
