Field sequential 액정 디스플레이(FSLCD)는 컬러필터를 사용하지 않아 높은 투과율 특성을 보이고 광
원으로 LED를 사용함으로써 색재현성이 매우 우수하다. 하지만 FSLCD(60Hz 구동)를 실현하기 위해서는 액정의 응답속도가 5ms이하로 고속응답 특성을 보여야 한다. 따라서 본 논문에서는 고속응답 ECB(electrically controlled birefringence) 셀의 최적 구조를 연구하여 5ms 이하의 응답시간을 얻었다. 그리고 ECB 모드에서 높은 구동전압과 시야각을 개선하기 위해 필름 보상을 연구하였다. 판상형 액정필름(discotic film)과 TAC(triacetyl cellulose) 필름의 위상차 값을 최적화함으로써 구동전압을 5V로 낮추고 상하좌우에서 160° 이상(CR>10:1)의 시야각을 실현하였다.

The field sequential liquid crystal display (FSLCD) has several advantages such as a high
transmittance due to no use of color filter and high color reproductivity because of use of LED backlight for a light source. To realize FSLCD, however, a response time of the LCD must be below 5ms for 60 Hz frequency of applied field. In this paper, we have optimized structure of electrically controlled birefringence (ECB) cell for fast response time and then achieved fast response time under 5ms in all grey scales. In addition, we have studied the film compensation to improve the operating voltage and viewing angle for the ECB cell. By optimizing the condition of the discotic and triacetyl cellulose (TAC) films, operating voltage decreases down to 5V and viewing angle was improved greatly over 160° with contrast ratio > 10:1 at horizontal and vertical direction, respectively.
