US Patent 7667391: Electrically excited organic light-emitting…
US 7667391 · granted 2010-02-23
Abstract
A light-emitting device, comprising: a multi-layer stack of materials supported on an optically transparent support member, a first spatial filter, and a second spatial filter spaced from the first spatial filter. The multi-layer stack including at least one organic light-emitting layers, an anode layer, and a cathode layer. The first spatial filter is disposed intermediate the multi-layer stack of materials and the second spatial filter.
