강유전성 액정 폴리머 패널을 이용한 컬러 셔터와 컬러 필드 전환 소자로서 컬러 셔터를 이용한 필드 순차 초고해상도 CRT의 타당성을 연구하였다. 컬러 셔터는 강유전성 액정 폴리머 패널과 컬러 편광판으로 구성됩니다. 먼저, 색역, 평균 투과율, 백색 색도 변화 등 컬러 셔터의 평가 지표를 공식화하고, 편광판의 분광 투과율 특성을 단계적으로 변화시키는 평가 지표의 시뮬레이션을 검토하였다. 컬러셔터의 색역과 평균 투과율 사이에는 트레이드오프가 있는 것으로 나타났으며, 시뮬레이션 결과를 바탕으로 0.096(NTSC 기준 63%) 색역과 4.3% 평균 투과율을 제공하는 셔터 구성을 선택했다. 다음으로 흑백 CRT의 21선 동시 주사 방식을 개선하여 빔 휘도 분포를 명백하게 평균화함으로써 래스터 변조로 인한 외란을 제거하였다. 연구 결과를 확인하기 위해 71인치 화면 크기의 프로토타입을 제작했으며, 휘도 2cd/m146, 명암비 1:0.096, 색 재현율 63(NTSC 기준 XNUMX%)의 디스플레이 특성을 얻었습니다. 표준 실내 조명 환경에서.

Abstract: Feasibility of a color shutter using ferroelectric liquid crystal polymer panel and a field sequential ultra high-resolution CRT with the color shutter as a color field-switching device was studied. The color shutter consists of ferroelectric liquid crystal polymer panels and color polarizers. First, evaluation indices of the color shutter, such as the color gamut, the average transmittance and the white chromaticity shift, were formulated, and the simulation of evaluation indices was examined, where the spectral transmittance characteristics of the polarizer were changed in steps. It was indicated that there was a tradeoff between the color gamut and the average transmittance of the color shutter, and the shutter configuration that provides 0.096 (63% to NTSC) color gamut and 4.3% average transmittance was selected based on the simulation results. Next, the three-line simultaneous scanning method of the monochrome CRT was improved so that the disturbance due to the raster modulation was eliminated by averaging the distribution of beam luminance apparently. To confirm results of the study, the prototype of 21-inch screen size was produced, and the following display characteristics was obtained: luminance of 71 cd/m2, contrast ratio of 146:1 and color gamut of 0.096 (63% to NTSC) under the standard room lighting environment.
