Abstract

The invention discloses a precise mask plate and a mask plate. The precise mask plate comprises a mask plate body which comprises at least one evaporation area, a shielding area at least partially surrounding the evaporation area and an edge area surrounding the evaporation area and the shielding area, wherein the evaporation area comprises a plurality of precise evaporation holes, the edge area comprises a plurality of edge area openings, and the shielding area comprises a plurality of grooves. According to the precise mask plate provided by the invention, due to the fact that the supporting strength difference of the shielding area, the edge area and the evaporation areas is small, the stress difference borne by all the areas can be reduced in the net stretching process of the precise mask plate, the probability that the precise mask plate is wrinkled after net stretching is reduced, and the product yield is improved.

Description

technical field [0001] The invention belongs to the technical field of vapor deposition equipment, and in particular relates to a precision mask plate and a mask plate. Background technique [0002] Now, in the preparation of OLED (Organic Light-Emitting Diode, organic electroluminescent diode) display panel, the evaporation process is used to form the light-emitting material layer. During the evaporation process, a precision mask is required. There is a wrinkle problem, which affects the product yield. Contents of the invention [0003] Embodiments of the present invention provide a precision mask and a mask. The precision mask provided in the present application has a greatly reduced probability of wrinkles after stretching, which improves product yield. [0004] In one aspect, an embodiment of the present invention provides a precision mask, including a mask body, the mask body includes at least one evaporation region, a shielding region at least partially surrounding ...
