| 20090026471 | LIGHT-SCATTERING STRUCTURE, LIGHT EMITTING DEVICE COMPRISING THE SAME AND METHOD OF FORMING THE SAME - A light-scattering structure with micron-scale or submicron-scale protruding portions is provided to improve the light extraction efficiency of light emitting devices. The protruding portions function as scattering sites and can be assembled closely. A method of forming a light-scattering structure is also provided, wherein all the conventional substrate materials can be used for the substrate of the light-scattering structure, and scattering sites of submicron-scale, micron-scale or larger size can be fabricated. | 01-29-2009 |
