METHOD FOR MANUFACTURING PHOSPHOR SHEET FOR WHITE OLED LIGHT SOURCES AND WHITE OLED LIGHT SOURCES MANUFACTURED USING THE SAME

摘要

The present invention relates to a method for manufacturing a fluorescent sheet to implement a white light source used in organic light emitting diode (OLED) and the white light source for the OLED implemented by using the same. In order to simplify the method for manufacturing the white OLED light source and reduce the manufacturing costs thereof, the present invention uses a low refractive index silicone resin to manufacture the fluorescent sheet and attaches the manufactured fluorescent sheet to the glass surface of an RGB OLED light source to implement the white OLED light source instead of directly injecting phosphors into an OLED to implement the white OLED light source. The method includes: (a) a process of coating first low refractive index silicon on the fluorescent sheet; (b) a process of dispersing RGB phosphors in the first low refractive index silicon; (c) a process of mixing second low refractive index silicon in the first low refractive index silicon having the RGB phosphors dispersed therein during the process (b); (d) a process of removing air bubbles; (e) a process of coating the fluorescent sheet which has the air bubbles removed in the process (d) onto a silicone release film and drying the coated fluorescent sheet; and (g) a process of laminating a fluorine release film or silicone release film onto the fluorescent sheet dried in the process (e).
