Abstract

A plate-shaped display device is partitioned into a meter display area and a HUD display area. Images displayed on the display device are visible on both front and rear surfaces of the display device. A direct image displayed on the meter display area is projected toward an eye range of a vehicle driver. A reflected image displayed on the HUD display area is firstly projected in a direction opposite to the eye range. Then, the reflected image is reflected at a magnifying mirror and a windshield, then finally projected toward the eye range.

Claims

1. A display apparatus comprising:

a display device for displaying an image being visible on both front and rear surfaces thereof,

whereby a first image to be displayed on a first area of the display device is directly projected toward a predetermined eye range, and a second image to be displayed on a second area of the display device, different from the first area, is at least reflected once before being projected toward the predetermined eye range.

2. The display apparatus as claimed in claim 1, further comprising an optical member disposed in the opposite direction to a direction of projecting the first image for reflecting the second image, last of all, toward the predetermined eye range.

3. The display apparatus as claimed in claim 2,

wherein the optical member projects the second image once toward a windshield of a vehicle for making the windshield reflect the second image, last of all, toward the predetermined eye range.

4. The display apparatus as claimed in claim 3, further comprising a second image generator for generating an inversely distorted image to compensate a distortion caused by the reflections of the optical member and the windshield.

5. The display apparatus as claimed in claim 1,

wherein one of the first and the second images is a generated image based on predetermined control signals, and the other is a view image around a vehicle taken by a vehicle on-board camera, said view image being substantially invisible to naked eyes.

6. The display apparatus as claimed in claim 2,

wherein one of the first and the second images is a generated image based on predetermined control signals, and the other is a view image around a vehicle taken by a vehicle on-board camera, said view image being substantially invisible to naked eyes.

7. The display apparatus as claimed in claim 3,

wherein one of the first and the second images is a generated image based on predetermined control signals, and the other is a view image around a vehicle taken by a vehicle on-board camera, said view image being substantially invisible to naked eyes.

8. The display apparatus as claimed in claim 4,

wherein one of the first and the second images is a generated image based on predetermined control signals, and the other is a view image around a vehicle taken by a vehicle on-board camera, said view image being substantially invisible to naked eyes.
