发明名称 ELECTROLUMINESCENT DEVICE HAVING A VARIABLE COLOR POINT
摘要 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).
