Abstract

A display device includes a light source irradiating excitation light and a window glass for a vehicle, such as a windshield, capable of emitting visible light through incident radiation of the excitation light, and allows the window glass for a vehicle to emit the light so as to display a message toward an outside of the vehicle by irradiation with the excitation light.

First claim

The invention claimed is:

1. A display device comprising:
a light source irradiating excitation light; and
a window glass for a vehicle, the window glass emitting visible light through incident radiation of the excitation light,
the window glass being allowed to emit the visible light so as to display a message toward an outside of the vehicle by irradiation with the excitation light,
wherein the window glass comprises two transparent plates and an interlayer provided between the two transparent plates so as to be in direct contact with the two transparent plates, and has a laminated glass structure in which the two transparent plates are bonded together via the interlayer,

wherein the interlayer is a resin film comprising a resin and a fluorescent material dispersed in the resin, the fluorescent material being capable of emitting visible light through incident radiation of the excitation light, and
wherein the light source is arranged in an interior of the vehicle, the interior of the vehicle being inward of an innermost surface of the window glass, and the innermost surface of the window glass is irradiated with the excitation light.

2. The display device according to claim 1 , wherein the message comprises at least one selected from the group consisting of a sentence, a trademark, a warning, and a message showing a vehicle condition.

3. The display device according to claim 1 , wherein the message is for surrounding cars or for pedestrians and light vehicles.

4. The display device according to claim 1 , wherein the display device is configured to display the message toward the outside of the vehicle based on an inputted voice.

5. The display device according to claim 1 , wherein the display device is configured to display the message toward the outside of the vehicle when it is inferred that a movable body is approaching.

6. The display device according to claim 1 , wherein the display device is configured to change a position of displaying the message toward the outside of the vehicle depending on a direction from which a movable body is approaching.

7. The display device according to claim 1 , wherein the light source is configured to irradiate the excitation light in a desired pattern such that the visible light emitted by the window glass forms the message, the message being a desired message among a plurality of messages, the desired message corresponding to the desired pattern of the irradiated excitation light.

8. A message transmission method comprising:
irradiating excitation light from a light source toward a window glass for a vehicle, the window glass emitting visible light through incident radiation of the excitation light; and
allowing the window glass to emit the visible light so as to display a message toward an outside of the vehicle by irradiation with the excitation light, thereby transmitting the message toward the outside of the vehicle,
wherein the window glass comprises two transparent plates and an interlayer provided between the two transparent plates so as to be in direct contact with the two transparent plates, and has a laminated glass structure in which the two transparent plates are bonded together via the interlayer,
wherein the interlayer is a resin film comprising a resin and a fluorescent material dispersed in the resin, the fluorescent material being capable of emitting visible light through incident radiation of the excitation light, and
wherein the light source is arranged in an interior of the vehicle, the interior of the vehicle being inward of an innermost surface of the window glass, and the irradiating of the excitation light comprises irradiating the innermost surface of the window glass with the excitation light.

9. The message transmission method according to claim 8 , wherein the message comprises at least one selected from the group consisting of a sentence, a trademark, a warning, and a message showing a vehicle condition.

10. The message transmission method according to claim 8 , wherein the message is for surrounding cars or for pedestrians and light vehicles.

11. The message transmission method according to claim 8 , further comprising displaying the message toward the outside of the vehicle based on an inputted voice.

12. The message transmission method according to claim 8 , further comprising displaying the message toward the outside of the vehicle when it is inferred that a movable body is approaching.

13. The message transmission method according to claim 8 , further comprising changing a position of displaying the message toward the outside of the vehicle depending on a direction from which a movable body is approaching.

14. The message transmission method according to claim 8 , wherein the excitation light is irradiated in a desired pattern such that the visible light emitted by the window glass forms the message, the message being a desired message among a plurality of messages, the desired message corresponding to the desired pattern of the irradiated excitation light.
