APPLICATION: US 2006-370663 8 Mar 2006. PRIORITY: TW 2005-94127032 9 Aug 2005. DOCUMENT TYPE: Patent CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Section cross-reference(s): 76 An org. light-emitting device is described comprising a first luminescent layer for generating a first component of a first color light; a second luminescent layer for generating a second component of the first color light; and a third luminescent layer, interposed between the first luminescent layer and the second luminescent layer, for generating a second color light different from the first color light, where when a voltage applied to the org. light-emitting device changes to cause decreasing luminescent intensity of the first luminescent layer, the luminescent intensity of the second luminescent layer may automatically increase to compensate for the decreased luminescent intensity of the first luminescent layer. .
