The invention provides a stereoscopic display device which is applied to the field of display. The stereoscopic display device comprises a light source device and an optical element. The light source device is used for outputting original beams to the optical element. The optical element obtains a first light beam at a first position according to the original light beam. The optical element is used for changing the transmission direction of the original beam at the second position to obtain a second beam. The stereoscopic display device further comprises a spatial light modulator or a diffusion screen. The spatial light modulator is used for modulating the first light beam and the second light beam according to different image information to obtain two paths of imaging light. The diffusion screen is used for diffusing the first light beam and the second light beam carrying different image information to obtain two paths of imaging light. According to the three-dimensional display device, the same light source device can be shared by adding the optical element, so that the cost of the three-dimensional display device is reduced.

    本申请提供了一种立体显示装置,应用于显示领域。立体显示装置包括光源器件和光学元件。光源器件用于向光学元件输出原始光束。光学元件用于在第一位置根据原始光束得到第一光束。光学元件用于在第二位置改变原始光束的传输方向,得到第二光束。立体显示装置还包括空间光调制器或扩散屏。空间光调制器用于根据不同的图像信息调制第一光束和第二光束,得到两路成像光。扩散屏用于对携带不同图像信息的第一光束和第二光束进行扩散,得到两路成像光。在本申请中,通过增加光学元件,可以共用同一个光源器件,从而降低立体显示装置的成本。
