Organic light emitting diodes (OLEDs) have many advantages like high performance and human-friendly light

source. Currently, light source market size is growing up and especially LED/OLED are soon to take over its

market. The light sources take up an average of 20 % of the lighting market. As of 2018, light sources will

comprise approximately 80 % with the expansion of OLEDs. Nevertheless, it was still a key issue that OLED

lighting is high cost than LED lighting. To surmount these problems, development of fusion and complex

materials using OLED lighting come to the fore.

In this study, our research has tended to focus on possibility of UV curable sealant with moisture capability.

Therefore, we fabricated OLED lighting using silicon based UV curable sealant and analyzed characteristics of

OLED lighting as a function of moisture scavenger contents of sealant, as observed in Fig. 1.
