Abstract
Official abstract text for this publication.
An electroluminescent device ( 9 ) for emitting light ( 7 ) whose color point is able to be set variably, comprising at least two electroluminescent regions ( 41, 42 ) that, to allow the same operating voltage to be applied, are arranged to be connected in parallel electrically, wherein the electroluminescent regions ( 41, 42 ) comprise—at least one first electroluminescent region ( 41 ) of a first electroluminescent material for emitting light in a first spectral band in accordance with a first luminance vs. voltage characteristic ( 81 ), and—at least one second electroluminescent region ( 42 ) of a second electroluminescent material for emitting light in a second spectral band that is not the same as the first spectral band, in accordance with a second luminance vs. voltage characteristic ( 82 ) that is not the same as the first luminance vs. voltage characteristic ( 81 ).
First claim
Opening claim text (preview).
