METAL MASK PLATE AND MANUFACTURING METHOD THEREFOR

Title:

METAL MASK PLATE AND MANUFACTURING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2017/117999

Kind Code:

A1

Abstract:

A metal mask plate (10) and a manufacturing method therefor. The metal mask plate (10) has a first main surface (S11) and a second main surface (S12) which are opposite to each other, and comprises a plurality of panel defining areas (100) which are arranged at intervals and a main frame portion (110). In each panel defining area (100), a plurality of through holes (101) for defining a pixel structure are arranged in a matrix. Each of the through holes (101) is in communication with the first main surface (S11) and the second main surface (S12) of the metal mask plate (10). Side walls of every two adjacent through holes (101) are directly connected to each other on the second main surface (S12) of the metal mask plate (10), so that the metal mask plate (10) between the two adjacent through holes (101) in the panel defining area (100) has a thickness D1. The main frame portion (110) of the metal mask plate (10) has a second thickness D2, and the first thickness D1 and the second thickness D2 satisfy |D1-D2|/D1 ≤ 20%. Therefore, the present invention can effectively avoid fold deformation caused by a thickness difference when a net is opened, so that the quality of an OLED display product manufactured using the fine metal mask plate can be effectively improved.
