Title:
SUBSTRATE AND METHOD FOR MANUFACTURING OLED DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/080195
Kind Code:
A1
Abstract:
A substrate (1), comprising a first base (11), a bonding layer (12), and a second base (13). The bonding layer (12) bonds between the first base (11) and the second base (13), and the bonding layer (12) is a UV decomposed adhesive. Also provided is a method for manufacturing an OLED device. A PI film layer (2) is manufactured in a substrate and is bonded to the base at the lowest layer by means of a UV decomposed adhesive, so that after the manufacture of an organic light-emitting device is completed, the base at the lowest layer can be easily lifted off only under ultraviolet irradiation without additionally bonding a backboard for support. The cost of base lift-off is greatly reduced, and the production yield is improved.
