Title:
STABLE ELECTROLUMINESCENT DEVICES
Document Type and Number:
WIPO Patent Application WO2002080627
Kind Code:
A3
Abstract:
An electroluminescent device comprising a transparent or translucent support, a transparent or translucent first electrode, a second conductive electrode and an electroluminescent phosphor layer sandwiched between the transparent or translucent first electrode and the second conductive electrode, chracterized in that the first and second electrodes each comprises a polymer or copolymer of a 3,4-dialkoxythiophene, which may be the same or different, in which the two alkoxy groups may be the same or different or together represent an optionally subsituted oxy-alkylene-oxy bridge; a display comprising the above-mentioned electroluminescent device; a lamp comprising the above-mentioned electroluminescent device; manufacturing processes for the above-mentioned electroluminescent devices; and the use of such devices for the integrated backlighting of static and dynamic posters and signage.
