논문 초록 (Abstract)
We investigated light extraction film based on polymer dispersed liquid crystal (PDLC) for application inorganic light emitting diodes (OLEDs). At least 30 seconds of direct UV irradiation process for curing PDLC filmon a bottom-emitting OLEDs was successfully achieved without damage on the intrinsic properties of the OLED.We demonstrated that high haze and transmittance can be tuned simultaneously by controlling the UV curingtime. By adding PDLC as an external layer without any additional treatment, the light scattering and extractionis increased. Consequently, a PDLC scattering film with 89.8% and 59.9 of total transmittance and hazerespectively, achieved about 16% of light intensity enhancement from integrating sphere measurement.
