Abstract

본 발명의 강유전성 액정 디스플레이는 하나의 액정 셀 뒤에 다른 하나의 액정 셀이 2개의 편광자 사이에 연속하여 배열된 2개의 액정 셀을 포함하는데, 하나의 액정 셀은 선형 전극을 포함하고 다른 액정 셀은 픽셀형 전극을 포함한다. 픽셀형 전극은 선형 전극에 동기하며 상 정보를 형성하면서 작동한다. 액정 셀의 배향과 굴절률은, 제어 전압이 역전되는 경우, 투과가 실제적으로 변경되지 않도록 선택한다. 2개의 디스플레이는 개폐각이 절대로 ±22.5°를 넘지 않도록 작동한다. 전압의 극성은 일반적으로 셀을 가로지르는 DC 전압이 없도록 주기적으로 반전된다.
