Abstract

A stereo display device includes a light source module, an image determining array, an imaging module, and a spatial dividing element. The light source module sequentially emits first and second lights to target regions in different directions. The image determining array includes pixel units respectively disposed in the target regions, and each of the pixel units sequentially provides first and second information to the first and second lights respectively. The imaging module guides the first light having the first information to form first imaging units, and guides the second light having the second information to form second imaging units. The spatial dividing element sends the first image units to first viewing regions respectively and sends the second image units to second viewing regions respectively, and two of the first image units corresponding to adjacent two of the pixel units are transmitted to the first viewing regions in different directions.

First claim

What is claimed is:

1. A stereo display device, comprising:
a light source assembly;

an imaging lens device, disposed adjacent to the image determining array, wherein the imaging lens device is optically coupled to the image determining array, and the imaging lens device receives the first light from the pixel units to form a plurality of first imaging units and receives the second light from the pixel units to form a plurality of second imaging units; and
a spatial dividing element optically coupled to the imaging lens device, wherein the spatial dividing element receives the first image units and sends the first image units to a plurality of first viewing regions respectively, and the spatial dividing element receives the second image units and sends the second image units to a plurality of second viewing regions respectively, wherein the first viewing regions and the second viewing regions are not overlapped, and two of the first image units corresponding to adjacent two of the pixel units are transmitted to the first viewing regions in different directions.

2. The stereo display device of claim 1 , wherein the first light and the second light are substantially parallel lights propagating in the different directions.

3. The stereo display device of claim 1 , wherein the spatial dividing element comprises a plurality of slanted cylindrical lenses, the pixel units are arrayed in a first direction and a second direction, and an extending direction of the slanted cylindrical lenses is not parallel with the first direction and the second direction, wherein each of the slanted cylindrical lenses in the first direction covers M number of the pixel units, wherein M is a positive integer, and each of the slanted cylindrical lenses has a slant angle δ of tan-1(1/M).

4. The stereo display device of claim 3 , wherein a sum width of each of the first image units and each of the second image units is cos(δ)/M times a length of the pixel units of the image determining array.

5. The stereo display device of claim 1 , further comprising:
a diffusing film, wherein the first image units and the second image units are formed thereon.

6. The stereo display device of claim 1 , wherein the imaging lens device comprises a plurality of lenses, and each of the lenses is disposed corresponding to each of the pixel units.

7. The stereo display device of claim 1 , wherein the imaging lens device comprises:
a first cylindrical lens, disposed at a side of the image determining array; and
a second cylindrical lens, disposed at another side of the image determining array, wherein an extension direction of the first cylindrical lens is substantially orthogonal to an extension direction of the second cylindrical lens.

8. The stereo display device of claim 1 , wherein the light source assembly comprises:
at least one first light source and at least one second light source, respectively radiating a first radiated light and a second radiated light; and
a lens optically coupled to the at least one first light source and at least one second light source, wherein the lens converts the first radiated light and the second radiated light to the first light and the second light, which are parallel lights.

9. The stereo display device of claim 8 , wherein the light source assembly further comprises a controller connected to the first light source and the second light source.

10. The stereo display device of claim 1 , wherein the light source assembly comprises:
