Description

【0001】
【発明の属する技術分野】
本発明は、例えばビル等の建物の外部にいる人に向けての広告、ニュース等の情報提供に用いる映像表示装置及び映像表示方法に関するものである。
【0002】
【従来の技術】
従来の映像表示装置は、建物の外壁にLED、液晶、ネオン灯等のディスプレイを設置することにより、映像を表示している。
【0003】
また、投影用の壁面に投影機を介して映像を表示する装置もある。
【0004】
【発明が解決しようとする課題】
しかしながら、前者のLED、液晶、ネオン灯等のディスプレイの表示装置は、建物の外壁や屋上に設置する必要があり、建物の外壁に設けた場合には、表示装置を設けた部分からは採光ができず、建物の美観を損ねたり、保守点検や安全管理のコストが高い等の問題がある。
【0005】
また、後者の壁面に投影機を介して映像を表示する装置においては、表示する壁面は投影用の壁面に適した加工を施す必要があり、壁面の材質、デザインの自由度を損ねてしまう。また、投影機は屋外に置くため、風雨等に対する対策も必要となる。
【0006】
本発明の目的は、上述の課題を解決し、太陽電池を備えた採光用の窓部を利用し、窓部を介して外部に画像情報を伝達する映像表示装置及び映像表示方法を提供することにある。
【0007】
【課題を解決するための手段】
上記目的を達成するための本発明に係る映像表示装置は、太陽電池パネルを含む半透光性を有するガラス窓と、該ガラス窓に内部から映像を投影する投影機とを有することを特徴とする。
【0008】
また、本発明に係る映像表示方法は、太陽電池を含む半透光性を有するガラス窓に、内部から投影機による映像を表示し、前記ガラス窓の外側から前記映像を視認できるようにすることを特徴とする。
【0009】
【発明の実施の形態】
本発明を図示の実施の形態に基づいて詳細に説明する。
図1は本実施の形態における映像表示装置の概略図を示しており、建物1の窓枠は太陽電池を含む半透光性を有するガラス窓2が嵌め込まれ、建物1内の天井3には、このガラス窓2に映像を投影するための投影機4が吊設されている。
【0010】
そして、ガラス窓2の太陽電池により発電した電力はバッテリ5に蓄電され、制御回路6を介して投影機4に供給されるようになっている。
【0011】
図2はガラス窓2の断面図を示しており、透明な2枚の板ガラス11間に、例えば膜厚数μmのアモルファスや多結晶や単結晶から成る薄膜太陽電池12を成膜したものが用いられている。この薄膜太陽電池12は膜厚が数μmなため、薄膜太陽電池12自体に透光性を有しており、ガラス窓2全体として半透光性とされ、太陽光を室内に採光することができる。
【0012】
また、図3に示すように、例えば2枚の透明な板ガラス11の間に板厚1mm程度のアモルファスや多結晶や単結晶の結晶系の太陽電池パネル13を適宜配置したものを用いてもよい。この結晶系の太陽電池パネル13自体は、住宅の屋根等に用いられている太陽光発電に用いられているものと同様のものであり透光性はない。しかし、図3に示すように分割した太陽電池パネル13を間隔を隔てて配置することにより、ガラス窓2全体としては半透光性を有し、ガラス窓2から採光することができ、窓の役割を果たすことができる。また、この場合のガラス窓2の透光率は、ガラス窓2の面積に対する太陽電池パネル13の面積を調整することにより適宜に設計することができる。
【0013】
これらの太陽電池はシリコン系、シリコン合金系、化合物系等の種々のものが知られているが、何れを用いてもよい。
【0014】
このような太陽電池を含む半透光性を有するガラス窓2を用いることにより、昼間は太陽光を受光し、太陽電池により発電を行い、室内照明の電力に使用したり、バッテリ5に蓄電しながら、ガラス窓2から太陽光を室内に採光することができる。また、このガラス窓2は半透光性であるため、室内を適度に遮光することができ、外部から室内が見え難くするブラインド効果も得られる。
【0015】
夜間においてはガラス窓2の半透光性を利用して、室内に設けた投影機4を用いて、昼間にバッテリ5に蓄電した電力によってガラス窓2に映像を投影し、建物の外部にいる人に向けて広告、ニュース等の情報を表示する。夜間においては周囲が暗いため、投影された弱い光による映像であっても外部から視認することができる。
【0016】
投影機4による投影映像は、ガラス窓2の外にいる人が正像として見るものであるから、左右反転した映像を投影する必要があり、また映像の種類は動画、静止画の何れでもよい。
【0017】
制御回路6は例えばタイマ回路等を有し、夜間の一定の時間から投影機4による投影を始め、所定の時間になると停止するようにすればよい。或いは、周囲が暗くなってから投影を始め、明るくなると停止するようにしてもよい。
【0018】
このようにして、バッテリ5に蓄電した電力により投影機4を動作させ、制御回路6のタイマ回路などが乾電池により作動するようにすると、室内の商用電力を全く使用せずに済む。広告主が場所を借用し、設備のみを負担すれば、建物の使用者から電力の供給を受けずに、広告を続けることができる。
【0019】
なお、上述の実施の形態では、投影機4とバッテリ5の電力により作動するようにしたが、バッテリ5を使用せずに、商用電力等によって作動させてもよいことは勿論である。
【0020】
本実施の形態においては、映像を建物のガラス窓に投影する場合について説明したが、例えばバスや電車等の乗物のガラス窓を利用することもできる。
【0021】
【発明の効果】
以上説明したように本発明に係る映像表示装置及び映像表示方法は、太陽電池を含むガラス窓を被投影面とすることにより、デザインや設計の自由度を損ねることなく、画像情報を伝達できる。

[0008]
Further, the image display method according to the present invention is to display an image by a projector from the inside on a semi-transparent glass window including a solar cell, and to allow the image to be visually recognized from the outside of the glass window. It is characterized by.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described in detail based on the illustrated embodiment.
FIG. 1 is a schematic diagram of an image display device according to the present embodiment. A window frame of a building 1 is fitted with a semi-transparent glass window 2 including a solar cell, and a ceiling 3 in the building 1 A projector 4 for projecting an image on the glass window 2 is suspended.
[0010]
The electric power generated by the solar cell in the glass window 2 is stored in the battery 5 and supplied to the projector 4 via the control circuit 6.
[0011]
FIG. 2 is a cross-sectional view of the glass window 2, which is formed by forming a thin film solar cell 12 made of, for example, an amorphous, polycrystalline or single crystal film having a thickness of several μm between two transparent glass plates 11. Have been. Since the thin-film solar cell 12 has a thickness of several μm, the thin-film solar cell 12 itself has a light-transmitting property, the entire glass window 2 is semi-transparent, and sunlight can be taken indoors. it can.
[0012]
Further, as shown in FIG. 3, for example, a solar cell panel 13 of an amorphous, polycrystalline or single crystal type having a thickness of about 1 mm may be appropriately disposed between two transparent glass sheets 11. . The crystalline solar panel 13 itself is the same as that used for solar power generation used for a roof of a house or the like, and has no translucency. However, by arranging the divided solar cell panels 13 at intervals as shown in FIG. 3, the glass window 2 as a whole has a semi-transmissive property, and can receive light from the glass window 2. Can play a role. In this case, the transmittance of the glass window 2 can be appropriately designed by adjusting the area of the solar cell panel 13 with respect to the area of the glass window 2.
[0013]
Various types of solar cells such as silicon-based, silicon alloy-based, and compound-based solar cells are known, and any of them may be used.
[0014]
By using the semi-transparent glass window 2 including such a solar cell, sunlight is received in the daytime, power is generated by the solar cell, and the power is used for indoor lighting or stored in the battery 5. Meanwhile, sunlight can be taken into the room from the glass window 2. Further, since the glass window 2 is semi-translucent, the interior of the room can be appropriately shielded from light, and a blind effect of making the interior difficult to see from the outside can be obtained.
[0015]
At night, the semi-transmissive property of the glass window 2 is used to project an image on the glass window 2 by the electric power stored in the battery 5 during the day, using the projector 4 provided in the room, and the user is outside the building. Display information such as advertisements and news to people. At night, the surroundings are dark, so that even an image due to the projected weak light can be visually recognized from the outside.
[0016]
Since the image projected by the projector 4 is what a person outside the glass window 2 sees as a normal image, it is necessary to project a horizontally inverted image, and the type of image may be either a moving image or a still image. .
[0017]
The control circuit 6 has, for example, a timer circuit and the like, and the projection by the projector 4 may be started at a certain time at night and stopped at a predetermined time. Alternatively, the projection may be started after the surroundings are dark, and may be stopped when the surroundings are bright.
[0018]
In this way, when the projector 4 is operated by the electric power stored in the battery 5 and the timer circuit and the like of the control circuit 6 are operated by the dry battery, it is not necessary to use indoor commercial electric power at all. If the advertiser rents the place and pays only for the equipment, the advertisement can be continued without receiving power supply from the building user.
[0019]
In the above-described embodiment, the projector 4 and the battery 5 are operated by electric power. However, it is needless to say that the projector 4 may be operated by commercial power or the like without using the battery 5.
[0020]
In the present embodiment, a case has been described in which an image is projected on a glass window of a building. However, for example, a glass window of a vehicle such as a bus or a train can be used.
[0021]
【The invention's effect】
As described above, the image display device and the image display method according to the present invention can transmit image information without impairing the design and the degree of freedom of design by using a glass window including a solar cell as a projection surface.
