    • A three dimensional display is provided which can. operate in an autostereoscopic mode, requiring no viewing aid, and a stereoscopic mode, requiring a viewing aid such as polarized spectacles. In the autostereosocopic mode, light from illuminators is imaged by lenses through LCD display panels at regions where the left and right eyes of an observer are located. Thus, a two dimensional image displayed on one panel is visible to the right eye of the observer whereas a two dimensional image displayed by the other panel to visible to the left eye of the observer. In the stereoscopic mode, light from the illuminators through the LCD panels is visible throughout an extended region by both eyes of the observer. However, the light from the panels is polarized in mutually perpendicular directions and the spectacles comprise polarizers for the left and right eyes which substantially pass only light corresponding to the left and right images, respectively.
    • 提供三维显示器。 以自动立体模式操作,不需要观看辅助,以及需要诸如偏光眼镜之类的观察辅助的立体模式。 在自动立体异味模式中,来自照明器的光通过透镜通过LCD显示面板在观察者的左眼和右眼所在的区域成像。 因此,在一个面板上显示的二维图像对于观察者的右眼是可见的,而另一个面板显示的二维图像对于观察者的左眼可见。 在立体模式中,通过观察者的双眼,通过LCD面板的照明器的光在整个扩展区域中是可见的。 然而,来自面板的光在相互垂直的方向上极化,眼镜包括左眼和右眼的偏振器,其基本上仅通过对应于左图像和右图像的光。
