Abstract

Embodiments of the present application provide a mask assembly and a manufacturing method thereof. The mask assembly includes a frame, a main mask, and an auxiliary mask. The main mask and the auxiliary mask are stacked, and the outer peripheral area of ​​the main mask and the outer peripheral area of ​​the auxiliary mask are respectively connected to the inner peripheral area of ​​the frame. The main mask is provided with a plurality of process holes, and the auxiliary mask is provided with at least one avoidance hole, and the process hole is directly opposite to a part of the corresponding avoidance hole. The stretching force between the auxiliary mask plate and the frame frame is greater than the stretching force between the main mask plate and the frame frame. The frame and the auxiliary mask are pre-formed as a component that is not easy to deform again and has high strength. After the main mask is connected to the frame in the first state, the frame in the first state will not be deformed again. Obvious deformation occurs, so that the flatness error of the main mask is small, and the shape accuracy of the process hole of the main mask and the position accuracy relative to the frame are high.

Description

technical field [0001] The present application relates to the technical field of masks, and in particular, the present application relates to a mask assembly and a preparation method thereof. Background technique [0002] During the manufacturing process of the display panel, the evaporation of the luminescent material needs to be realized through the mask plate assembly. The mask assembly usually includes a frame and a mask. The outer peripheral area of ​​the mask is connected to the inner peripheral area of ​​the frame. The mask is provided with a plurality of process holes, and the luminescent material is plated on the display panel through the process holes. preset position on . [0003] In the mask plate assembly, the flatness of the mask plate and the position accuracy of the process hole in the mask plate relative to the frame frame are two important indicators. In order to ensure the flatness of the mask, it is usually necessary to stretch the mask and then connect...
