Abstract:
A method of reducing the internal reflected light in an OLED device comprising the step of either scattering light emitted from the OLED or removing light emitted from the OLED. An OLED device comprising a color changing medium film, a transparent substrate, and either a means for scattering light emitted from the OLED or a means for removing light emitted from the OLED such that the internal reflected light is reduced.
