Abstract
Claims
1. A passive glasses-free stereoscopic display device suitable for positioning a portable electronic device having a flat screen capable of generating a planar image, the passive glasses-free stereoscopic display device comprising: a body including a housing portion defining a positioning space for positioning the portable electronic device and having an opening through which the flat screen can be viewed; a transparent cover having an arc-shaped cross-section and disposed on the body, and having a transparent viewing area facing the flat screen; and a Fresnel lens having an arc-shaped structure disposed on the transparent viewing area of the transparent cover and facing the planar image, for refracting light from the planar image.
2. The passive glasses-free stereoscopic display device as described in claim 1, wherein, The housing of the main body has two positioning holes. The passive naked-eye stereoscopic display device also has a fixing member. The fixing member has two parts respectively positioned on the sides of the positioning holes and a fixing part located between the two sides for positioning the portable electronic device in the positioning space.
3. The passive glasses-free stereoscopic display device as described in claim 2, wherein, The fixing part of the fastener is elastic.
4. The passive glasses-free stereoscopic display device as described in claim 1, wherein, The transparent door cover has two horizontally obscured areas, and the transparent viewing area is located between the two obscured areas.
5. The passive glasses-free stereoscopic display device as described in claim 1, wherein, The housing portion of the main body has a bottom wall, a top wall located above the bottom wall, and an arc-shaped side wall disposed between the bottom wall and the top wall. The bottom wall has a first pivot groove, and the top wall has a second pivot groove corresponding to the first pivot groove. The transparent door cover also has a first pivot portion pivotally disposed in the first pivot groove and a second pivot portion pivotally disposed in the second pivot groove.
6. The passive glasses-free stereoscopic display device as described in claim 1, wherein, The passive naked-eye stereoscopic display device also has an elastic buffer body, which is located in the positioning space of the main body and is used by the portable electronic device to be positioned against it.
7. The passive glasses-free stereoscopic display device as described in claim 6, wherein, The elastic buffer is a light-blocking structure.
8. A passive glasses-free stereoscopic display device suitable for positioning a portable electronic device having a flat screen capable of generating a planar image, the passive glasses-free stereoscopic display device comprising: a body including a housing portion capable of defining a positioning space for positioning the portable electronic device, the housing portion having an arc-shaped transparent viewing area corresponding to the flat screen; and a Fresnel lens having an arc-shaped structure disposed in the transparent viewing area of the body and facing the planar image, for refracting light from the planar image.
9. The passive glasses-free stereoscopic display device as described in claim 8, wherein, The positioning space of the main body has a lower opening and an upper opening facing the lower opening. The passive naked-eye stereoscopic display device also has a lower cover and an upper cover. The lower cover is located at the lower opening and the upper cover is located at the upper opening.
10. The passive glasses-free stereoscopic display device as described in claim 9, wherein, The lower cover has a lower positioning part, the upper cover has an upper positioning part, and the portable electronic device is positioned between the lower positioning part and the upper positioning part.
