根据双目视差原理和柱面光栅的分光特性研制了液晶三维自由立体显示器。该立体显示器由二维平板液晶显示器和柱面光栅有机耦合而成。采用九个视差图实现了三维静态、动态和视频的显示效果。一个19英寸的立体显示器具有相对应的平面显示器相同的亮度、对比度和色彩,其分辨率在垂直和水平方向都有合理的下降。该立体显示器的观看距离是(1000±500) mm,视角为90o,可供多人不戴立体眼镜就能自由观看立体图像。
According to the binocular parallax principle and the spectral characteristics of the cylindrical grating, a three-dimensional liquid crystal display is developed. The three-dimensional display by the two-dimensional flat-panel liquid crystal display and cylindrical grating organic coupling made. Using nine parallax images to achieve a three-dimensional static, dynamic and video display. A 19-inch stereo display has the same brightness, contrast and color as the corresponding flat-panel displays, with a reasonable reduction in both vertical and horizontal resolution. The viewing distance of the stereoscopic display is (1000 ± 500) mm, the viewing angle is 90 °, and a stereoscopic image can be freely viewed by a plurality of people without stereoscopic glasses.
