Title:
LARGE-AREA ELECTROLUMINESCENT LIGHT-EMITTING DEVICES
Document Type and Number:
WIPO Patent Application WO2005120136
Kind Code:
A3
Abstract:
An electroluminescent light-emitting device is manufactured in a semi-continuous process (80, 40, 64) using vapor deposition technology to reduce the thickness of the dielectric layers (72, 52). The phosphor (34), dielectric (52) and electrode (58) layers are deposited sequentially on a flexible web substrate (30), preferably PET (14) coated with conductive ITO (12), which is passed through the deposition sections (74, 32, 54, 82, 84) on a continuous basis. By depositing the dielectric layers in vacuum (50), very thin layers are possible, which yields increased transparency and electrical capacitance. Accordingly the resulting multi-layer structure is suitable for the manufacture of large-area EL devices.
