Abstract: |
The invention discloses an organic electroluminescent element, which contains a layer of optical modulating layer in the organic functional layer, wherein the organic functional layer concludes at least two luminous areas; the light is mixed to obtain the white light; the optical modulating layer lies between two luminous areas, which has the property of cavity and electron transmission; the luminous chromaticity of element can be adjusted through the thickness of optical modulating layer, which generates white light with pure chromaticity. |
