Abstract

There is a problem in a dual emission device emitting light out of both surfaces that an image on the surface and an image on the rear surface are different from each other (either image is mirror-reversed). A dual emission device is disclosed in which either light emitted from the light-emitting device is reflected by glass including a semi-transmissive film to display on glass an image same as another image obtained also from the light-emitting device, and simultaneously, external information can be viewed through the glass. A mirror can be arranged between the dual emission device and the glass including a semitransparent film.

Claims

1. A vehicle comprising;

a car navigation system;

an interior comprising a light-emitting device including an anode and a cathode; and

a front glass with a semi-transmissive film,

wherein information from the car navigation system out of one of the anode and the cathode is displayed on the interior, and

wherein the information from the car navigation system out of the other one of the anode and the cathode is displayed on the semi-transmissive film.

2. The vehicle according to claim 1, wherein a second information of at least one of speed meter and clock is also displayed on the interior and the semi-transmissive film.

3. The vehicle according to claim 1,

wherein the vehicle further comprising a sensor detecting external information of the vehicle, and

wherein a third information from the sensor is also displayed on the interior and the semi-transmissive film.

4. The vehicle according to claim 1, wherein the vehicle is one of a sports car, a track, a bus, a station wagon,

an track ambulance, a tractor, a tanker, a train, and a motor cycle.

5. A vehicle comprising;

a camera detecting external information of the vehicle;

a light-emitting device including an anode and a cathode; and

a front glass with a semi-transmissive film,

wherein information from the camera out of one of the anode and the cathode is displayed on the light-emitting device, and

wherein the information from the camera out of one of the other of the anode and the cathode is displayed on the semi-transmissive film.

6. The vehicle according to claim 5, wherein a second information of at least one of speed meter and clock is also displayed on the interior and the light-emitting device.

7. The vehicle according to claim 5,

wherein the vehicle further comprising a sensor detecting external information of the vehicle, and

wherein a third information from the sensor is also displayed on the light-emitting device and the semi-transmissive film.

8. The vehicle according to claim 5, wherein the vehicle is one of a sports car, a track, a bus, a station wagon,

an ambulance, a tractor, a tanker, a train, and a motor cycle.

9. A vehicle comprising;

a camera detecting external information of the vehicle;

a light-emitting device including an anode and a cathode; and

a rear window glass with a semi-transmissive film,

wherein information from the camera out of one of the anode and the cathode is displayed on the light-emitting device, and

wherein the information from the camera out of one of the other of the anode and the cathode is displayed on the semi-transmissive film.

10. The vehicle according to claim 9, wherein a second information of at least one of speed meter and clock is also displayed on the light-emitting device and the semi-transmissive film.

11. The vehicle according to claim 9,

wherein the vehicle further comprising a sensor detecting external information of the vehicle, and

wherein a third information from the sensor is also displayed on the light-emitting device and the semi-transmissive film.

12. The vehicle according to claim 9, wherein the vehicle is one of a sports car, a track, a bus, a station wagon,

an ambulance, a tractor, a tanker, a train, and a motor cycle.

13. A vehicle comprising;

a camera detecting external information of the vehicle,

a light-emitting device including an anode and a cathode;

a front glass with a first semi-transmissive film; and

a rear window glass with a second semi-transmissive film,

wherein information from the camera out of one of the anode and the cathode is displayed on the light-emitting device, and

wherein the information from the camera out of the other one of the anode and the cathode is displayed on the first semi-transmissive film and the second semi-transmissive film.

14. The vehicle according to claim 13, wherein a second information of at least one of speed meter and clock is also displayed on the light-emitting device, the first semi-transmissive film and the second semi-transmissive film.

15. The vehicle according to claim 13,

wherein the vehicle further comprising a sensor detecting external information of the vehicle, and

wherein a third information from the sensor is also displayed on the light-emitting device, the first semi-transmissive film and the second semi-transmissive film.

16. The vehicle according to claim 13, wherein the vehicle is one of a sports car, a track, a bus, a station wagon,
