Abstract

A curved display apparatus includes a projector, first and second mirrors, a curved screen, an infrared illuminator, an infrared camera, and a controller. The projector is configured to project an image onto a projection area. The first mirror is configured to reflect the image projected from the projector. The second mirror is configured to reflect the image reflected from the first mirror. The curved screen is configured to display the image reflected from the second mirror. The infrared illuminator is configured to output infrared rays onto the curved screen. The infrared camera is configured to capture an infrared image of the curved screen. The controller is configured to determine the image displayed on the curved screen and control the projector according to the determined image, determine a light reflection area based on the infrared image, and control the projector to rearrange an image displayed in the light reflection area.

First claim

What is claimed is:

1. A curved display apparatus for a vehicle, comprising:
a projector configured to project an image onto a predetermined projection area;
a first mirror configured to reflect the image projected from the projector;
a second mirror configured to reflect the image reflected from the first mirror;
a curved screen configured to display the image reflected from the second mirror;
an infrared illuminator configured to output infrared rays onto the curved screen;
an infrared camera configured to capture an infrared image of the curved screen; and
a controller configured to determine the image displayed on the curved screen and control the projector according to the determined image,
wherein the controller is configured to determine a light reflection area on the curved screen based on the infrared image and control the projector to rearrange an image that is displayed in the light reflection area.

2. The curved display apparatus of claim 1 , wherein the controller is configured to control the projector to display a black image in the light reflection area.

3. The curved display apparatus of claim 1 , wherein the first mirror is an aspherical mirror manufactured based on a curvature value of the curved screen.

4. The curved display apparatus of claim 1 , wherein
the image displayed on the curved screen comprises a user interface configured with a plurality of selectable objects, and
the controller is configured to control the projector to display the plurality of objects a region except for the light reflection area.

5. The curved display apparatus of claim 4 , wherein the controller is configured to determine a touched position on the curved screen based on the infrared image.

6. The curved display apparatus of claim 5 , further comprising
an application driver configured to execute an application function according to control instructions of the controller,
wherein when it is determined that the touched position corresponds to any one of the plurality of objects, the controller is configured to generate control instructions for operating an application function mapped to the selected object.

7. The curved display apparatus of claim 4 , wherein the controller is configured to determine a display area of each of the plurality of objects based on a selection frequency of each of the plurality of objects.

8. The curved display apparatus of claim 1 , wherein the controller is configured to the projector to display a black image in a region within a predetermined range from the light reflection area.

9. The curved display apparatus of claim 1 , wherein the controller is configured to determine, as the light reflection area, a region having coordinates of pixels that deviate from a predetermined pixel value range.
