LICHT EMITTIERENDE EINRICHTUNG |
摘要 |
<p>An organic light emissive device, which comprises: an anode; a cathode; and an organic light emissive region between the anode and the cathode, which region comprises: a layer of blue light electroluminescent organic material which emits light having first CIE co-ordinates by exciton radiative decay; and a layer of longer wavelength electroluminescent organic material which intrinsically emits light having second CIE co-ordinates by exciton radiative decay; wherein the layers of blue light and longer wavelength materials are selected so that the organic light emissive region emits white light falling within a region having a CIE X coordinate equivalent to that emitted by a black body at 3000-9000K and CIE gamma co-ordinate of said light emitted by a black body.</p> |
