Abstract： |
The invention relates to an organic electrochromic lightening component, specially a white organic electrochromic lightening component that includes cathode layer, anode layer and multi organic layer which is between the cathode layer and anode layer, thereinto the lightening layer of the organic layer is multi layer configuration which comprises multi lightening layers with different lightening efficiency, interface is between the lightening layers, it characterized in that said lightening layers are arranged according to that the lightening layer is anear to the interface of the lightening layer that the distributing density is small. The invention obtains the organic electrochromic lightening component that the lightening efficiency is maximized and fineness of the color is increased by arrangement of the lightening layer. |
