Optical three-dimensional display device

[0020] Example 1

[0021] An optical stereo display device, such as Figure 1 to Figure 4 As shown, it includes a projector 1 and a lens array screen 2. The lens array screen 2 or the projector 1 is provided with a translation and rotation mechanism. The lens array screen 2 performs a translation and rotation movement through a translation and rotation mechanism, and the lens array screen 2 uses a translation and rotation mechanism. Performing translational and rotational movement, the light emitted by the projector 1 is incident on the lens array screen 2. With the translation and rotation of the translation and rotation mechanism, the direction of the emitted light of each lens unit 3 on the lens array screen 2 changes synchronously with the translation and rotation. .

[0022] Preferably, the lens array screen 2 is configured as a reflective lens array screen 2 or a transmissive lens array screen 2.

[0023] Preferably, each lens unit 3 on the lens array screen 2 corresponds to a b
