Multi-viewpoint three-dimensional display system and display method

[0061] The optical path diagram of the first scheme of the multi-viewpoint three-dimensional display system constructed based on the I-type time-division multiplexing projection unit of the present invention is as follows figure 1 As shown, the I-type time-division multiplexing projection units are arranged in a plane, including a control unit and several I-type time-division multiplexing projection units 10, and all I-type time-division multiplexing projection units 10 are arranged adjacent to each other in a plane; each I-type time-division multiplexing projection unit The multiplexing projection unit 10 includes a display screen 11, a projection lens 12 and a clear aperture array 13; the display screen 11 is used to display optical image information; the projection lens 12 is used to project the image of the display screen 11 onto the projection surface; the clear aperture The array 13 is composed of a plurality of clear apertures and placed at the aperture of the projection...

[0082] The optical path diagram of the first scheme of the multi-viewpoint three-dimensional display system constructed based on the type II time-division multiplexing projection unit of the present invention is as follows Figure 7 As shown, the Type II time-division multiplexing projection unit is arranged in a plane, and its difference from the first scheme of Embodiment 1 is that the time-division multiplexing projection unit 10 is a Type II time-division multiplexing projection unit, which The distance between the display screen 11 and the projection lens 12 is equal to the focal length of the projection lens 12; II type time division multiplexing projection unit 10 also includes an auxiliary lens 20, a field lens 30 and a diffusion sheet 40 attached to the field lens 30, and the diffusion sheet 40 It is used to scatter incident light; the auxiliary lens 20 images the display screen 11 on the projection surface; the center of the field lens 30 is set on the projection surf...

[0097] The optical path diagram of the first scheme of a multi-viewpoint three-dimensional display system constructed based on a type III time-division multiplexing projection unit of the present invention is as follows Figure 9 As shown, the Type III time-division multiplexing projection unit is arranged in a plane, and its difference from the first scheme of Embodiment 1 is that the time-division multiplexing projection unit 10 is a Type III time-division multiplexing projection unit, which The distance between the display screen 11 and the projection lens 12 is greater than the focal length of the projection lens 12, and the display screen 11 is projected into a real image on the projection surface through the projection lens 12; III time division multiplexing projection unit 10 also includes a field lens 30 and is attached to the field lens 30 The scattering sheet 40 is placed, and the scattering sheet 40 is used to scatter the incident light, and the center of the field l...
