Abstract

We introduce a parallax barrier type autostereoscopic display in order to overcome the limited viewing angle of the conventional parallax barrier type displays. The proposed method adopts a special structure of double pairs of ITO that have a common TN-LC at the core of the conventional parallax barrier. Compared with the conventional parallax barrier type displays, the proposed display uses moving parallax barriers and eye tracking system to make stereoscopic view images adapted to the movement of viewer. We implemented a prototype of the proposed dual layer parallax barrier system, and verified that the proposed autostereoscopic display maintains seamless 3D views even when a viewer's head is moving.

본 논문에서는 기존 무안경식 3D 디스플레이의 제한된 시야각으로 인한 3D 시청에서의 불편함을 해소하기 위해 새로운 패렐랙스 배리어 방식을 제안한다. 제안된 방식은 기존 패렐랙스 배리어의 TN-LCD 구조에서 LC를 공유하는 이중 계층의 ITO 쌍을 추가하였으며, 시선 추적 장치에 의해 시청자의 위치를 감지하여 자동으로 3D 시야각을 시청자의 위치에 맞도록 변화 시킬 수 있는 이중 계층의 패렐랙스 구조를 갖는다. 제안한 이중 계층 패렐랙스 배리어 방식을 시제품으로 구현하고 실험한 결과, 제안한 방식의 유효성을 확인할 수 있었다.
