specific Embodiment approach 1
[0014] Such as figure 1 As shown, it is a schematic structural diagram of the stereoscopic projection display device in this specific embodiment. The stereoscopic projection display device includes a stereoscopic projector 1 , a holographic projection film screen 3 and glasses 5 . The stereo projector 1 is used to project a sequence of image frames that can be used for stereoscopic display. The position of the stereo projector 1 enables the light projected by the stereo projector to be projected onto the holographic projection film screen 3. The glasses 5 and the stereo projector 1, it is used for the user to watch the picture emitted by the holographic projection film screen 3 after wearing it.
[0015] Specifically, the stereo projector 1 can be an active stereo projector or a passive stereo projector.
[0016] When it is an active stereoscopic projector, the projected image frame sequence is an image frame sequence in which the left and right eye image sequences are alter...
specific Embodiment approach 2
[0027] The difference between this specific embodiment and Embodiment 1 is that in this specific embodiment, the positional relationship between the projector and the projection film constitutes a rear-projection positional relationship, that is, the projector is located on the back side of the holographic projection film screen, The light projected by the stereo projector is refracted and transmitted by the holographic projection film screen and reaches the user watching. In the first specific embodiment, the positional relationship between the projector and the projection film is a front-projection positional relationship.
[0028] like Figure 4 As shown, it is a schematic structural diagram of the stereoscopic projection display device in this specific embodiment. The stereoscopic projection display device includes a stereoscopic projector 2 , a holographic projection film screen 4 and glasses 6 . Stereo projector 2 projects image frame sequence for stereoscopic display,...
