Description

Technical Field

[0002] At present, there are devices in the prior art that use a projection device to project images onto a transparent projection board with a holographic film pasted thereon by means of rear projection to present a holographic effect. However, because all the projected images are displayed on the same plane, the holographic effect presented in this way is not very ideal in terms of sensory perception. Therefore, in order to increase the holographic effect of the projected image, a flexible projection display screen is used and bent at a certain angle to increase the projected holographic effect. When the flexible projection display screen is bent, it is not convenient to adjust the bending deformation of the flexible projection display screen by touching the flexible projection display screen.
