White and colored organic electroluminescent devices using single emitting material by novel color change technique |
摘要 |
An organic electroluminescent device such as a light-emitting diode is disclosed, in which the emission layer comprises a single emitting material at different aggregate state to obtain constant chromaticity white emission. Correspondingly, a novel configuration has been developed to get white emission and color change in the organic EL devices.
