Abstract

The invention discloses a precision metal mask and a mask component thereof, comprising: an effective display area; two welding areas, the two welding areas are respectively located at two ends of the effective display area in the length direction On the side, at least one of the welding areas is a set welding area, and the set welding area is provided with a first through hole. According to the precision metal mask of the present invention, by setting the first through hole in the set welding area, it is beneficial to the stress distribution of the precision metal mask during the average stretching process, reducing the risk of wrinkles in the welding area, thereby ensuring welding Accuracy, reduce the situation of virtual soldering, improve the quality of evaporation.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a precision metal mask and a mask assembly having the same. Background technique [0002] Generally, in the preparation process of the display panel, the precision metal mask plays an important role, especially in the preparation process of the OLED display panel, it directly determines whether the organic light-emitting material can be accurately evaporated on the corresponding OLED substrate. . [0003] However, in the related art, in the process of welding the precision metal mask plate to the metal frame, a virtual welding situation often occurs and the welding is not strong, which affects the quality of evaporation. SUMMARY OF THE INVENTION [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a precision metal mask. By setting the first through hole in the set welding a...
