Abstract

A curved display apparatus for a vehicle includes a laser scanning projector projecting an image onto a predetermined projection area. A first plane mirror is configured to reflect the image projected from the laser scanning projector, and a second plane mirror is configured to reflect the image reflected from the first plane mirror. A curved screen is configured to display the image reflected from the second plane mirror. A controller is configured to control output timing of laser beams outputted from the laser scanning projector based on a shape of the curved screen.

Claims

1. A curved display apparatus for a vehicle, comprising:

a laser scanning projector projecting an image onto a projection area;

a first plane mirror configured to reflect the image projected from the laser scanning projector;

a second plane mirror configured to reflect the image reflected from the first plane mirror;

a curved screen configured to display the image reflected from the second plane mirror; and

a controller configured to control output timing of laser beams outputted from the laser scanning projector based on a shape of the curved screen.

2. The curved display apparatus of claim 1, wherein the laser scanning projector comprises:

a laser generator configured to output the laser beams;

a laser combiner configured to combine the laser beams projected from the laser generator; and

a microelectromechanical systems (MEMS) scanner configured to project the image onto the projection area by scanning the laser beams.

3. The curved display apparatus of claim 2, wherein the laser combiner comprises:

a plurality of collimator lenses that are disposed in each of projection directions of the laser beams projected from the laser generator; and

a plurality of dichroic mirrors corresponding to each of the projection directions of the laser beams projected from the plurality of collimator lenses.

4. The curved display apparatus of claim 2, wherein the MEMS scanner comprises a MEMS mirror scanning the laser beams.

5. The curved display apparatus of claim 4, wherein the controller controls a direction of the laser beams scanned by the MEMS mirror according to a curvature value of the curved screen.

6. The curved display apparatus of claim 2, wherein the laser generator comprises:

a red laser source configured to project a red laser beam;

a green laser source configured to project a green laser beams; and

a blue laser source configured to project a blue laser beam.

7. The curved display apparatus of claim 6, wherein the laser generator further comprises an infrared laser source configured to project an infrared laser beam.

8. The curved display apparatus of claim 7, further comprising:

an infrared camera photographing an infrared image reflected from the curved screen; and

an application driver executing an application function according to control instructions of the controller,

wherein the controller determines a touched position on the curved screen based on the infrared image.

9. The curved display apparatus of claim 8, wherein the image displayed on the curved screen comprises a user interface configured with a plurality of selectable objects, and if the touched position corresponds to any one of the plurality of objects, the controller generates the control instructions for operating the application function mapped to a selected object.
