Abstract

The invention discloses a method for manufacturing an OLED mask. The mask master is obtained as a medium through the existing mask manufacturing method, and combined with an electroforming process, a large number of OLED masks with good practical application effects can be produced. A new method is provided for the manufacture of the OLED mask, and the production cost is reduced. Moreover, no exposure machine and photomask are needed in the manufacturing process of the OLED mask in the present invention, which can simplify the production equipment and production process, thereby further reducing the production cost, and has good practical application effect.

Description

Technical field [0001] The invention relates to the field of flat display devices, in particular to a method for manufacturing an OLED mask. Background technique [0002] Organic Light Emitting Diode (OLED) is a new type of display and lighting technology. Generally, OLED thin films are prepared by vacuum evaporation technology, that is, organic / metal materials are heated in a vacuum environment (~10-5Pa), the materials are sublimated by heat, and through the patterns on a mask with a certain pattern, the substrate An organic / metal film with a certain shape is formed on the surface. [0003] OLED masks are mainly made by welding metal sheets with a certain pattern to the metal frame. The existing metal flakes are mainly obtained by chemical etching. However, due to the high price of metal sheets obtained by etching at present, their large-scale use is limited. [0004] In order to obtain an OLED mask with a lower price, at present, technicians are trying to use an electroforming ...
