Even if auto-stereoscopic and polarization based 3D displays are not working with the same principles, their common aim is to provide two different images in the eyes of the observer. In this paper we show that Fourier optics instrument for viewing angle measurements can be applied to both types of displays. Luminance measurements are made at different locations and what will be seen by an observer in front of the display is predicted. Precise 3D characteristics can be derived and direct comparison becomes possible.

In the constructed auto-stereoscopic display system for one observer. 1.stereoscopic images displayed on a special LCD are made on a large concave mirror. 2.The view-zone limiting aperture is set between the projection lens and the concave mirror. 3.The real image of the aperture is made at the observer's eye position by the concave mirror. 4.The observer's eye-position tracking of the view-zone is realized. 5.At same time, stereoscopic image changes automatically according to the eye position of the observer.

We have developed the Scan-backlight Stereoscopic LCD that is a kind of field-sequential -Stereoscopic LCD combining the Dual- Directional- Backlight and the fast-response OCB panel. The Dual-Directional-Backlight using a double-sided prism sheet can change the direction of light by switching the LED light sources. The OCB panel using Feed-Forward Drive can realize frame rate of 120 Hz. As a result, the Scan-backlight Stereoscopic display works at its original resolving power, and produces flicker-free stereoscopic images. This auto- stereoscopic display can resolved the problems of the double images and the pseudoscopic images in case of watching at oblique angles.

SDI has been developing mobile 3D display for years. For mobile applications, we adapted parallax barrier method. We have developed auto stereoscopic swing 3D display in which people can 3D image in both portrait and landscape mode. Furthermore to increase 3D resolution, we have developed a high resolution 3D display using time division multiplexing parallax barrier method

A natural 3D image is considered by many people to be next-step in evolution of displays. This paper introduces autostereoscopic 3D of 60-view number, which is made using slanted lenticular lens array and LCD of 15.1 inch diagonal size and 3200 by 2400 pixel numbers and presents the results of our prototype. Due to its large view number, smooth motion parallax is observed and the visual fatigue is reduced.

A new technique to construct an auto-stereoscopic display that offers massive horizontal parallax images is proposed Multiple telecetnric imaging systems are arranged in a modified 2D array. The horizontal parallax images displayed by LCD panels are imaged to be superimposed on a 3D screen. All parallax images are displayed in the different horizontal directions because all imaging systems have different horizontal positions. The difference of the vertical display directions due to the imaging system's vertical positions is canceled by a vertical diffuser placed at the 3D screen. Observers can percept 3D images with the binocular disparity, the vergence, and the smooth motion parallax. In addition, the accommodation function may also work because a number of parallax images are displayed with a very small angle interval in the horizontal direction. A prototype 3D display including 64 color LCD panels was constructed.

시청 피로 정도는 3차원 디스플레이의 성능을 평가할 수 있는 여러 요소 중 하나이다. 3차원 디스플레이의 시청 피로도를 개선하기 위한 많은 연구 중 시차 조정 방법은 3차원 영상의 시차를 적절한 분포를 가지도록 하는 간단한 방법으로써 많은 연구가 진행되고 있다. 본 논문에서는 시차 장벽 방식의 오토스테레오스코픽 3차원 디스플레이에서 시차 분포가 시청 피로에 미치는 영향을 기반으로 수평 영상 이동 방식을 이용하여 시차 조정하는 방법을 제안한다. 제안하는 방법은 Speeded-Up Robust Feature(SURF)를 이용하여 3차원 영상의 시차 분포를 구하고, 이전 연구를 통해 구한 시차 분포가 시청 피로에 미치는 영향을 토대로 시차 조정 정도를 결정하고 3차원 영상의 시차를 조정한다. 제안 방법의 성능을 평가하기 위하여, 우리는 실제 제작된 시차 장벽 방식의 오토스테레오스코픽 3차원 디스플레이를 사용하여 최적 시청 거리에서 주관 평가를 실시한다. 실험 결과는 다양한 시차 분포를 가지는 3차원 영상에 대하여 제안 방법을 적용 한 후 시청 피로 정도가 감소함을 보여준다.
