An active diffuser for reducing speckle and a laser display device having the active diffuser

摘要

The active diffuser for reducing speckle according to the present invention is coated on the other surface of the electroactive polymer film having at least one scattering pattern, the first transparent electrode coated on one side of the electroactive polymer film and the electroactive polymer film Including the second transparent electrode, the scattering pattern of the electroactive polymer film is characterized in that the shape of the pattern is changed by the voltage applied through the first transparent electrode and the second transparent electrode.
