Abstract
The present invention provides a mask, a method for manufacturing a mask, and a method for manufacturing an OLED panel. The method of manufacturing a mask includes: providing a metal plate; defining a first blocking area, a second blocking area and a coating area located between the first blocking area and the second blocking area; reducing a thickness of the coating area; and intervally hollowing the coating area to thereby form skeletons which are intervally disposed and connected between the first blocking area and the second blocking area and hollowing areas which are surrounded by the first blocking area, the second blocking area and the skeletons. Accordingly, the present invention can improve the production yield.
Claims13
A method of manufacturing a mask, comprising steps of:
- providing a metal plate;
- defining a first blocking area, a second blocking area, and a coating area located between the first blocking area and the second blocking area on the metal plate;
- reducing a thickness of the coating area to thereby make the thickness of the coating area be less than that of the first blocking area and the second blocking area;
- performing an intervally hollowing processing on the coating area to thereby make the coating area be formed with skeletons and hollowing areas, wherein the skeletons are intervally disposed and connected between the first blocking area and the second blocking area, and the hollowing areas are surrounded by the first blocking area, the second blocking area and the skeletons;
- providing a frame and installing the hollowing processed metal plate onto the frame to thereby obtain the mask;
- wherein the step of reducing a thickness of the coating area comprises:
- etching the coating area to thereby etch off a part of the coating area along a thickness direction of the coating area.
A method of manufacturing a mask, comprising steps of:
- providing a metal plate;
- defining a first blocking area, a second blocking area, and a coating area located between the first blocking area and the second blocking area on the metal plate;
- reducing a thickness of the coating area to thereby make the thickness of the coating area be less than that of the first blocking area and the second blocking area;
- intervally hollowing the coating area to thereby make the coating area be formed with skeletons and hollowing areas, wherein the skeletons are intervally disposed and connected between the first blocking area and the second blocking area, and the hollowing areas are surrounded by the first blocking area, the second blocking area and the skeletons.
A mask comprising:
- a metal plate, wherein the metal plate comprises a first blocking area, a second blocking area and a coating area located between the first blocking area and the second blocking area, the coating area comprises skeletons which are intervally disposed and connected between the first blocking area and the second blocking area and hollowing areas which are surrounded by the first blocking area, the second blocking area and the skeletons, a thickness of the skeletons is less than that of the first blocking area and the second blocking area;
- and
- a frame, wherein the metal plate is installed onto the frame.
