Abstract

일면 상에 입사되는 주변 및 관찰자를 향해 후방 산란되는 상태와 입사가시 광이 매체를 통해 다른면의 광 흡수기로 매체를 통해 전달되어 관찰자가 어두운 디스플레이를 감지하고, 광기전 구조(25)가 전달되는 가시광에 응답하여 출력 전압을 생성하기 위한 광 흡수기로 이용되는 상태간에 스위칭할 수 있는, PDLC 재료 등의, 액정 매체(20)를 갖는, 예를들면 페이퍼 화이트형 디스플레이의 밝은 배경 상에 어두운 문자를 디스플레이 할 수 있는 액정 디스플레이 소자(10), 휴대용 컴퓨터 등의 장비에서 생성된 전력은 배터리 전원(45)을 보충하는데 이용될 수 있다.
