Abstract

In one aspect, an encapsulation sheet, a method of manufacturing an organic light emitting display device using the encapsulation sheet, and an organic light emitting display device is provided. The encapsulation sheet includes a carrier film; and a first sheet formed on the carrier film, wherein the first sheet comprises at least one of tin fluorophosphates glass, chalcogenide glass, tellurite glass, borate glass, and phosphate glass.

Claims

1. An encapsulation sheet, comprising:

a carrier film; and

a first sheet formed over the carrier film,

a second sheet between the carrier film and the first sheet, wherein the second sheet comprises tungsten, and wherein the first sheet comprises at least one of chalcogenide glass, tellurite glass, borate glass, and phosphate glass, and

wherein the first sheet is separable from the carrier film.

2. The encapsulation sheet of claim 1 wherein the second sheet is patterned.

3. An encapsulation sheet, comprising:

a carrier film;

a first sheet formed over the carrier film,

the first is separable from the carrier film, and the first sheet comprising at least one of tin fluorophosphates glass, chalcogenide glass, tellurite glass, borate glass, and phosphate glass; and

a second sheet formed between the carrier film and the first sheet, the second sheet patterned as stripes, and the second sheet formed of tungsten.

4. The encapsulation sheet of claim 3, wherein the first sheet comprises tin fluorophosphates glass and the tin fluorophosphates glass comprises tin (Sn) by 20 to 80 weight %, phosphorus (P) by 2 to 20 weight %, oxygen (O) by 3 to 20 weight %, and fluorine (F) by 10 to 36 weight %.
