| 摘要 |
The present invention relates to a wavelength conversion film and, more particularly, to a film which is used in a package of an optical source device and improves the light conversion efficiency of the device by including a nano-phosphor and a nanopattern as a wavelength conversion film which is mass-produced. The nanopattern is formed on the wavelength conversion film. The nanopattern is a dot pattern or a line pattern. The present invention improves the light conversion efficiency of the device. |
