Abstract

A two dimensional point light source array can replace both the viewing zone forming optics and the back light panel in the contact-type 3 dimensional imaging systems based on LC panels. This replacement can make the system structure of the 3 dimensional imaging systems no different from that of the conventional LCD and can reduce undesirable visual effects caused by the viewing zone forming optics. The problem with the point light source array is the visual quality deterioration of the system due to the non-ideal nature of the array.

본 연구는 2차원 PLS(Point Light Source) 배열과 디스플레이 장치의 조합을 통하여 시역형성용 광학판이 없는 3차원 영상을 재생하는 방법에 관한 것이다. PLS를 사용하여 3차원 영상을 디스플레이 하는 경우 기존의 시차장벽(parallax barrier), 렌티큘러(lenticular), 마이크로 렌즈(microlens lens) 등의 광학판을 사용할 때 발생하는 여러 가지 광학적 문제점 등을 해소할 수 있다. PLS로 사용된 LED 광원이 가져야 할 특성을 조사하였으며 PLS 배열을 통한 입체영상 디스플레이의 시역에 대해 실험을 통하여 입증 하였다.
