Abstract

A 3D display system includes a rotational base, a 3D projecting device, an image capturing device, and a controller. The 3D projecting device is rotatably disposed on the rotational base. The image capturing device is disposed on the 3D projecting device. The controller is electrically connected to the image capturing device, the rotational base, and the 3D projecting device.

First claim

What is claimed is:

1. A 3D display system, comprising:
a rotational base;
a 3D projecting device, comprising:
a housing, rotatably disposed on the rotational base;
a displayer, disposed in the housing and configured to emit light with a first light transport direction;
an optical lens, disposed in the housing and configured to change the first light transport direction of the light into a second light transport direction;
a polarizer disposed in the housing, the polarizer defining a triangular space together with the displayer and the optical lens, and configured to reflect the light with the first light transport direction and permitting the light with the second light transport direction to transmit therethrough; and

at least one pivoting mechanism disposed in the housing and configured to drive each of the displayer, the optical lens and the polarizer to move relative to the housing;
an image capturing device, disposed on the 3D projecting device; and
a controller, electrically connected to the image capturing device, the rotational base, and the 3D projecting device.

2. The 3D display system according to claim 1 , wherein the light emitted by the displayer passes through the polarizer, the optical lens, and the polarizer in sequence.

3. The 3D display system according to claim 1 , wherein the image capturing device and the polarizer face toward the same direction.

4. The 3D display system according to claim 1 , further comprising:
a box, accommodating the displayer, the optical lens, and the polarizer therein;
wherein the pivoting mechanism is pivotally connected to the box, electrically connected to the controller, and configured to simultaneously change positions of the displayer, the optical lens, and the polarizer relative to the housing.

5. The 3D display system according to claim 1 , wherein the at least one pivoting mechanism comprises:
a first pivoting mechanism, electrically connected to the controller and the 3D projecting device, and configured to change a position of the displayer relative to the housing.

6. The 3D display system according to claim 1 , wherein the at least one pivoting mechanism comprises:
a second pivoting mechanism, electrically connected to the controller and the 3D projecting device, and configured to change a position of the optical lens relative to the housing.

7. The 3D display system according to claim 1 , wherein the at least one pivoting mechanism comprises:
a third pivoting mechanism, electrically connected to the controller and the 3D projecting device, and configured to change a position of the polarizer relative to the housing.

8. The 3D display system according to claim 1 , wherein the rotational base comprises a rotary column and the 3D projecting device is fixed on the rotary column.

9. The 3D display system according to claim 1 , wherein the polarizer covers the displayer and the optical lens.
