초록
기존의 디스플레이가 전달하던 2차원 평면 정보를 넘어서서 실제와 같은 3차원 공간 정보를 전달하는 3D 디스플레이 기술이 최근 주목을 받고 있다. 3D 디스플레이를 구현하는 방법은 170년이 넘는 역사에 걸맞게 매우 다양하지만 사용자가 입체감을 느끼기 위하여 특수 안경을 착용해야 하는 안경식과 착용할 필요가 없는 무안경식으로 크게 나눌 수 있다. 본 논문에서는 이러한 3D 디스플레이 기술 중 대형 크기인 3DTV에 적합한 기술들의 원리와 장단점을 살펴보고 현재 수준에서 개선되어야 할 사항들과 이를 위해 필요한 요소 기술들에 대하여 전망한다.
Abstract
The three-dimensional (3D) display, which can provide 3D information to the observer, attracts much attention nowadays. With a long history over hundred and seventy years, there exist various kinds of 3D display technologies and it is common to categorize them into two groups - technologies with special glasses and technologies without special glasses. In this paper, the pros and cons of 3D display technologies which are suitable for large-size 3DTV are reviewed and the technology requirements for future 3DTV are also discussed.
