Abstract
The present invention provides a mask for an OLED thin-film encapsulation, including a hollow portion having an opening configured to form a thin-film encapsulation layer, a cover portion configured to cover a non-thin-film encapsulation region on a substrate, the cover portion having a first surface contacting with the substrate, and a second surface away from the substrate, the cover portion having an edge surrounding the opening and close to a side of the cover portion contacting with the substrate, and at least one portion of the edge of the cover portion formed with a beveled corner.

A mask for an OLED (organic light-emitting diode) thin-film encapsulation, comprising:
- a hollow portion having an opening configured to form a thin-film encapsulation layer on a substrate;
- and
- a cover portion configured to cover a non-thin-film encapsulation region on the substrate, wherein the cover portion has a first surface contacting with the substrate, and a second surface away from the substrate;
- wherein the cover portion has an edge surrounding the opening and close to a side of the cover portion contacting with the substrate, at least one portion of the edge of the cover portion is formed with a beveled corner;
- an area of the first surface is smaller than an area of the second surface;
- and the second surface covers the first surface.
