Abstract

In this paper, we proposed the novel hybrid guest-host liquid crystal display using the negative charged black particles in order to improve the low contrast ratio. We designed patterned electrode in order to switch the charged particle to the opposite electrode and improved the electro-optical characteristics by optimize the mixture of guest materials. In Comparison with the Heilmeier Guest-Host mode, proposed hybrid guest-host structure showed 80% reduction of transmittance in dark state, and the performance was examined by comparing contrast ratio.

본 논문에서는 Guest-Host 디스플레이의 문제점인 낮은 명암대비비를 해결하기 위해서 음전하로 대전 된 흑색입자를 이용한 고성능 하이브리드 Guest-Host 디스플레이를 제안하였다. 우리는 패턴 된 전극구조의 설계로 전압에 따른 입자의 스위칭을 고려하였으며, 염료 및 입자의 혼합비를 최적화하여 전기광학특성을 향상 시켰다. 따라서 기존 Heilmeier Guest-Host 디스플레이에 비교하여 dark 특성을 80%이상 향상시켰으며, 명암대비비를 비교분석함으로써 제안 된 모드의 성능 우수성을 검증하였다.
