Appeal 2007-1261
Application 10/196,523
The Appellants claim a method for preparing a layered composite
capable of forming a light-emitting device. This method is adequately
represented by claims 1 and 7, which read as follows:
1. A method for preparing a layered composite capable of forming a
light-emitting device, said method comprising the steps:
(a) obtaining a substrate material, said substrate material comprising
a layer of an electrode material;
(b) screen-printing at least one emitting layer on said substrate
material, wherein said at least one emitting layer is comprised of alternating
layers of electron transport material and hole transport material, said hole
transport material selected from the group of poly(vinyl carbazole),
poly(arylene vinylene), and starburst polyamines, said at least one emitting
layer capable of functioning as a light-emitting layer in a light-emitting
device; and
(c) applying a conductive paste material to said emitting layer, said
conductive paste material comprising a layer of an electrode material.
7. A method according to claim 1 wherein at least one of said at least
one emitting layer comprises a light emitting molecule selected from the
group consisting of tris(8-quinolinolato)aluminum, bis(2-(2-hydroxyphenyl)
pyridinato)beryllium, anthracene, tris(2-phenylpyridine)iridium doped in a
host 4,4'-N,N'-dicarbazol-biphenyl, their derivatives and blends thereof.
