Abstract

A portable computer with a projecting function includes a main body, a display module, a pivot, and a projection module. The display module is connected to the main body via the pivot and capable of rotating relative to the main body. The projection module is disposed on the pivot for projecting the information of the main body. The portable computer is, for example, a laptop computer, or a tablet computer.

Claims

1. A portable computer with a projecting function, comprising:

a main body storing information;

a pivot connected with the main body;

a display module connected to the main body via the pivot to be capable of rotating relative to the main body; and

a projection module disposed on the pivot for projecting the information.

2. The portable computer according to claim 1, wherein the projection module comprises a projection lens located in an extension direction of a rotating axis of the pivot.

3. The portable computer according to claim 1, wherein the display module is capable of rotating an angle relative to the main body to allow the display module and the main body to form an inverted V-shape structure.

4. The portable computer according to claim 3, wherein the angle is less than 180 degrees to enable a display surface of the display module to be set inwards.

5. The portable computer according to claim 3, wherein the angle is greater than 180 degrees to enable a display surface of the display module to be set outwards.

6. The portable computer according to claim 1, wherein the pivot is a multi section fixing pivot for fixing the display module at different angles after the display module rotates relative to the main body.

7. The portable computer according to claim 1, wherein each of the main body and the display module has an anti-skid member for avoiding skidding.

8. The portable computer according to claim 7, wherein the anti-skid members are opposite to the pivot.

9. The portable computer according to claim 7, wherein the anti-skid members have a patterned grain.

10. The portable computer according to claim 1, wherein the portable computer is a laptop computer or a tablet computer.

11. The portable computer according to claim 1, wherein the projection module is a liquid crystal on silicon (LCOS) projection module or a digital light processing (DLP) projection module.

12. A portable computer with a projecting function, comprising:

a main body storing information;

a pivot connected with the main body;

a display module connected to the main body via the pivot to be capable of rotating relative to the main body, wherein the display module includes a display surface and a marginal surface which are near each other; and

a projection module, disposed on the marginal surface of the display module, for projecting the information.

13. The portable computer according to claim 12, wherein the main body comprises an anti-skid member for avoiding skidding.

14. The portable computer according to claim 13, wherein the anti-skid member has a patterned grain.

15. The portable computer according to claim 12, wherein the portable computer is a laptop computer or a tablet computer.

16. The portable computer according to claim 12, wherein the projection module is a liquid crystal on silicon (LCOS) projection module or a digital light processing projection module.
