초록

본 연구에서는 LCD BLU에 적용 가능한 면광원용 저온소성 형광체 페이스트(paste)를 제조하여 그 특성을 검토하였다. 형광체 paste에는 저온 소성용 아크릴 레진을 바인더로 사용하였으며, 그 열분해특성을 검토한 결과 400℃에서 잔탄이 0.1 wt%이하인 것을 확인 할 수 있었다. 본 연구에서 제조한 paste로 스크린 인쇄를 통해 면광원용 device를 제작한 결과 형광체 휘도에 대해 100%에 가까운 발광특성을 나타내었다.

In this study we have manufactured and characterized the low temperature calcined phosphor paste that can be used as a flat light source for LCD BLU. For the phosphor paste, the low temperature calcined acryl resin was used as the binder. From the result of thermal decomposition measurement, residual carbonaceous materials was found to be less than 0.1 wt% at 400℃. A flat light source device that was made by screen printing using the manufactured paste showed a near 100% luminous efficiency compared to the luminance of the phosphor.
