Abstract:
A stereoscopic image system using a multi-layered display device is provided to improve depth of a stereoscopic image to be displayed by afterimage effects by electrically changing positions of central depth planes. A multi-layered image display(100) includes a first display(110) for projecting an applied basic image and a second display(120) for displaying the basic image projected from the first display, wherein the second display comprises plural display devices. An image processor(300) generates each basic image corresponding to the plural display devices and provides the generated basic image to the first display. A voltage controller(400) electrically controls the plural display devices and operates one display device, corresponding to the basic image provided from the first display in a state different from the rest display devices. A lens array(200) comprises plural basic lenses and displays a stereoscopic image by forming the basic images displayed in the display devices, in different central depth planes.

본 발명은 렌즈 어레이를 이용한 입체 디스플레이 시스템에 관한 것이다. 본 발명에서는 영상 처리부가 3차원 영상의 재생을 위한 기초 영상을 다수 생성하며, 이러한 기초 영상들은 화상 표시부로 전달되어 표시된다. 화상 표시부에서 표시되는 기초 영상은 렌즈 어레이의 행렬로 배열된 다수의 기초 렌즈에 의하여 각각 결상되어 3차원 영상으로 재생된다. 특히, 렌즈 어레이는 제1 방향 또는 제2 방향으로 렌즈 어레이의 중심이 구부러지도록 소정 곡률을 가지므로, 상기 각각의 기초 영상이 화상 표시부 상에 표시되는 기초 영상 영역의 경계가 상기 렌즈 어레이의 곡률 반경의 중심에서 각 기초렌즈의 양 끝을 연결한 직선이 상기 화상 표시부와 만나는 지점으로 재정의 되어 시야각이 증가된다. 또한, 렌즈 어레이와 화상 표시부 사이에 격벽을 위치시켜 플립트(Flipped) 영상, 즉 이웃하는 렌즈를 통해 보이는 원하지 않는 영상을 제거하여, 보다 시야각이 현저하게 증가한 입체 영상을 표시할 수 있다.
