Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a light control glass and an automotive window system.
[0002]
[Prior art]
In recent years, a light control glass has been proposed. Dimmable glass is a type of glass that can freely adjust the light transmittance and the degree of coloring of the glass itself, so that the light can be blocked without using a curtain or shutter, or the separated side of the glass cannot be seen. A glass that can be made possible.
[0003]
As the light control glass, for example, those using liquid crystal, those using a thermochromic method, a photochromic method, and the like are known. In the case of using liquid crystal, what is normally in a transparent state is one in which light is blocked by changing the orientation of liquid crystal molecules by applying a voltage, and the thermochromic method and photochromic method are respectively A substance that is colored by applying heat and irradiating light of a specific wavelength is used.
[0004]
Further, there have been proposed ones using such a light control glass for a window of a building (for example, see Patent Document 1) and those using a light control glass for a window of an automobile (for example, see Patent Document 2).

[0006]
[Problems to be solved by the invention]
However, what is proposed in the above-mentioned documents and the like is to reduce the irradiation of sunlight mainly to suppress an increase in the room temperature and to secure a view.
[0007]
On the other hand, in recent years, crimes such as vandalism have increased, but due to poor housing conditions in the city center, more cars are parked in outdoor parking lots away from home, and the money left inside the car is visible from outside. It can be said that the vehicle is often parked in an unpopular place in a state that is easy to do.
[0008]
As a countermeasure against such a situation, a light transmittance is reduced by attaching a film to a glass surface. However, in this case, it takes time to attach and detach, and it cannot be attached to the front of the vehicle.
[0009]
Therefore, it is desired to use the light control glass in a vehicle window by combining it with another security system.
[0010]
Liquid crystal is currently used in various fields as a thin display device, but cannot be used as a display device in the above-mentioned light control glass. In order to use a liquid crystal as a display device, a backlight and a color filter are necessary, and if these are provided, they cannot be used as a window.
[0011]
As for the photochromic glass using the photochromic system or the thermochromic system, the entire surface of the glass is merely colored in the same color, so that an image cannot be displayed naturally.
[0012]
If it is possible to use a light control glass that is a transparent panel, has a function as a display device, and can change the light transmittance, the interior of the vehicle should be invisible. In this case, it is difficult to cause vandalism on the vehicle, and when an abnormality is detected, the surroundings can be notified to the surroundings by the function of the light control glass as a display device.
[0013]
This is common to buildings such as stores, and it is possible to display the presence of an intruder toward the street when the presence of an intruder is detected, while keeping the inside of the store invisible after closing the store. It is.
[0014]
The present invention has been made in view of the above points, and has as its object to provide a vehicle window system using a light control glass and a light control glass having an image display function.
[0015]
[Means for Solving the Problems]
The present invention provides a light control glass using an organic EL element, and a window system for an automobile that drives the light control glass in response to signals from an ignition key switch device and various sensors.
[0016]
More specifically, the present invention provides the following.
[0017]
(1) An organic electroluminescent element layer, which is a light control glass that can be adjusted to have an arbitrary light transmittance, and is formed by sandwiching a transparent light emitting layer that emits light by applying a predetermined voltage between two transparent electrodes. Is sandwiched between two transparent plates.
[0018]
According to the invention of the above (1), in the light control glass, “two organic electroluminescent element layers formed by sandwiching a transparent light emitting layer that emits light by applying a predetermined voltage between two transparent electrodes are used. The use of light control glass that is thinner and lighter and easier to handle compared to known light control glass using liquid crystal, etc. Becomes possible.
[0019]
In recent years, light control glass using liquid crystal, electrochromic glass, or the like has been proposed. Liquid crystals are widely used as thin display devices in the field of display devices. However, as a thin display device, an organic electroluminescence (organic EL) display has attracted attention in terms of being able to be made thinner and being a self-luminous type as compared with a liquid crystal. .
[0020]
Therefore, by adopting the technology of the organic EL display for the light control glass, it becomes possible to obtain a light control glass that can be made thinner and lighter than the conventional liquid crystal light control glass.
[0021]

[0023]
Unlike a liquid crystal display device, a liquid crystal light control glass does not use a backlight or a color filter, so if the light transmittance is reduced, it only becomes cloudy and opaque. Can not be selected. On the other hand, since the organic EL element is of a self-luminous type, its coloring is determined according to the color emitted from the luminous body.
[0024]
Therefore, by using an organic EL element capable of color development as in the present invention for the light control glass, it is possible to select an arbitrary coloring.
[0025]
(3) The light control glass according to (1) or (2), wherein an image can be displayed by the organic electroluminescence element layer.

Can be displayed instead of being colored, so that various information can be notified to the outside.
[0027]
Since the light control glass is a glass in which the light transmittance is originally variable, it is configured only for adjusting the light transmittance entirely or partially.
[0028]
However, when the organic EL element is used for the light control glass as in the present invention, the organic EL element develops its own color, so that a plurality of colors can be formed at once, and the image display device can be used. It is.
[0029]
For example, when used in a car or store window, it is possible to display an advertisement, connect to a security sensor, and report any abnormalities.
[0030]
(4) An organic electroluminescent element layer, which is a light control glass that can be adjusted to have an arbitrary light transmittance, and is formed by sandwiching a transparent light emitting layer that emits light by applying a predetermined voltage between two transparent electrodes. And a photochromic glass layer which is colored by reacting with light of a specific wavelength emitted from the light emitting layer, is sandwiched between two transparent plates.
[0031]
According to the invention described in the above (4), in the light control glass, “an organic electroluminescent element layer formed by sandwiching a transparent light emitting layer that emits light by applying a predetermined voltage between two transparent electrodes; The photochromic glass layer, which is colored in response to light of a specific wavelength emitted from the light-emitting layer, is sandwiched between two transparent plates. " Since the photochromic glass layer is colored, the light transmittance is sufficiently changed, and when light other than light having a wavelength for coloring the photochromic glass layer is emitted, it functions as a display device to the outside. Can also be provided.
[0032]
(5) An automotive window system comprising a light control glass adjustable to an arbitrary light transmittance and a control device for controlling the light control glass, wherein the system is connected to an ignition key switch device. Light transmittance changing means for changing the light transmittance of the light control glass is provided, and the light transmittance change means changes the light transmittance of the light control glass according to removal of a key to the switch device. A window system for an automobile, wherein the window system performs a control operation.
[0033]
According to the invention of the above (5), in the automotive window system using the light control glass, "the system is a light transmittance changing the light transmittance of the light control glass connected to an ignition key switch device. Changing means is provided, and the light transmittance changing means executes control for changing the light transmittance of the light control glass in response to removal of a key to the switch device. Since it is possible to make the inside of the vehicle invisible when a driver is absent such as when parking, it is possible to have a security function such as theft prevention of luggage placed inside the vehicle.
[0034]
The window of the automobile needs to have a predetermined light transmittance in order to secure the safety of maintaining the visibility. However, it is desirable to reduce the light transmittance of the window as much as possible in order to ensure privacy inside the vehicle when the vehicle is stopped, prevent theft of luggage placed in the vehicle when parking, and the like.
[0035]
Therefore, as in the present invention, by interlocking the window made of the light control glass with the ignition key switch device, when the key is removed, the light transmittance of the window is automatically reduced so that the inside of the vehicle can be visually recognized. By making it impossible, it is possible to have a security function.

The organic electroluminescent element layer formed as described above is sandwiched between two transparent plates ", thereby making the light control glass thinner and lighter.
[0038]
In recent years, light control glass using liquid crystal, electrochromic glass, or the like has been proposed. Liquid crystals are widely used as thin display devices in the field of display devices. However, as a thin display device, an organic EL display has attracted attention in that it can be made thinner and that it is a self-luminous type as compared with liquid crystal.
[0039]
Therefore, by adopting the technology of the organic EL display for the light control glass, it becomes possible to obtain a light control glass that can be made thinner and lighter than the conventional liquid crystal light control glass.
[0040]

Abnormality notification means, and the abnormality notification means performs control for causing the light control glass to emit light in response to detection of the abnormality detection means, '' whereby the window itself emits light when an abnormality is detected. Thus, the abnormality can be notified to the outside.
[0042]
The window of the automobile needs to have a predetermined light transmittance in order to secure the safety of maintaining the visibility. However, it is desirable to reduce the light transmittance of the window as much as possible in order to ensure privacy inside the vehicle when the vehicle is stopped, prevent theft of luggage placed in the vehicle when parking, and the like. Therefore, it has been proposed to use the light control glass for an automobile window.
