초록

액정표시장치의 고효율 백라이트 집광시트로 활용하기 위하여 배면 개구형 집광시트를 설계 및 분석하였다. Microlens array sheet, 피라미드 array sheet, 그리고 cone array sheet에 대해서 자체 정렬에 의한 배면 개구 형성 특성을 비교 분석한 결과, microlens array sheet가 가장 우수하였고, 다음으로 피라미드 array sheet였으며, cone array sheet가 가장 부적합하였다.

Optical sheets with apertures on the opposite side of the substrate are designed and analyzed in order to use them as high efficiency light concentration sheets in LCD edge-lit backlight. Formation of apertures by self-aligning exposure were analyzed for the microlens array sheet, pyramid array sheet, and cone array sheet and the microlens array sheet showed the best performance for the formation of apertures by the self-aligning exposure.
