Abstract

There is provided laminated glass including a display suited to windshield glass.

The laminated glass 30 according to the present invention is configured by bonding, through substantially rectangular interlayers 16, 18 and 20, a substantially rectangular glass plate 12 and a substantially rectangular glass plate 14, which have the same sizes as each other. The laminated glass 30 has a plurality of rectangular organic EL displays 34, 36 and 38 as displays built at certain positions in the laminated glass 30. In other words, the laminated glass 30 according to the present invention suited to windshield glass is configured by interposing the organic EL displays 34, 36 and 38 between the interlayer 16 and the interlayer 20 disposed between the glass plate 12 and the glass plate 14.

Claims

1. A laminated glass utilized as windshield glass for a vehicle, comprising:

at least two glass plates and an interlayer interposed there between;

at least one display interposed between the at least two glass plates; and

wherein the at least one display is disposed in a peripheral edge area of the laminated glass as seen from the interior of the car,

wherein the interlayer comprises three layers the middle layer of which surrounds the display,

wherein the at least one display comprises a flat panel display, and

wherein the at least one display is disposed on a car-interior side of an optically shielding layer disposed on the peripheral edge area of the laminated glass and wherein the optical shielding layer is black ceramic.

2. The laminated glass according to claim 1, wherein the display is disposed in each of left and right vertical edge areas of the laminated glass.

3. The laminated glass according to claim 2, wherein the at least one display has dimensions of from 80 to 200 mm in length and from 100 to 150 mm in width.

4. The laminated glass according to claim 1, wherein the at least one display is disposed at a central position in a top edge area or a bottom edge area of the windshield glass.

5. The laminated glass according to claim 4, wherein the at least one display has dimensions of from 70 to 150 mm in length and from 150 to 350 mm in width.

6. A display device for a vehicle, comprising:

the laminated glass defined in claim 1;

an image sensor capturing an image showing a scene behind the vehicle; and

an image processor displaying the image showing the scene behind the vehicle on the display disposed in the laminated glass, the image being captured by the image sensor.

7. The display device according to claim 6, wherein:

the image sensor captures images showing scenes on lateral sides behind the vehicle; and

the image processor displays an image showing a scene on a right side behind the vehicle on a first display disposed in a right vertical edge area of the laminated glass, and an image showing a scene on a left side behind the vehicle on a second display disposed in a left vertical edge area of the laminated glass, both of the images being captured by the image sensor.

8. The display device according to claim 6, wherein:

the image sensor captures an image showing a central scene behind the vehicle; and

the image processor displays the image showing the central scene behind the vehicle on the display disposed at a central position in a top edge area or bottom edge area of the laminated glass, the image being captured by the image sensor.

9. The display device according to claim 1, wherein the flat panel display is a liquid crystal display.

10. The display device according to claim 1, wherein the flat panel display is an organic electro-luminescent display.

11. The display device according to claim 10, wherein the flat panel display is a transmissive type of organic electro-luminescent display.

12. The display device according to claim 1, wherein the interlayer is made from an ethylene-vinyl acetate copolymer.

13. The display device according to claim 1, wherein the middle layer has a thickness equal to the thickness of the display.
