Description

本考案は薄型の映像投写スクリーンに関し、プロジェクターから投写された映像が、明るく、高解像度であり、広視野角度かつ高コントラスト比を実現できる薄型の液晶調光フィルム(2)を用いて、既設或いは新設の透明ガラス(1)或いは透明合成樹脂製の壁面や窓や扉に、高透明度を有し、充分に密着し液晶調光フィルム(2)全体を余り無く、また隙間無く接着固定することができ、しかも接着面にキズ跡や汚れを残さず再剥離が可能な薄型透明両面粘着フィルム(3)を合体させ、或いは介在させて、フレームや補強板を一切使用せずに全面を直接接着させ、印加電圧の調節による調光機能により透視可能な透明状態から透視不可能な白色の状態までの間で、不透明度を可変調節しながら、室内に設置されたプロジェクター(12)から静止画或いは動画を投写して様々に表現し、屋外から鑑賞することができる液晶利用の調光機能付き薄型映像投写スクリーンフィルムを提供することができることになった。    The present invention relates to a thin image projection screen, which uses a thin liquid crystal light control film (2) capable of realizing an image projected from a projector with high brightness, high resolution, a wide viewing angle and a high contrast ratio. Highly transparent, fully adhered to the newly-installed transparent glass (1) or transparent synthetic resin walls, windows and doors, and can be adhesively fixed to the entire liquid crystal light control film (2) without any gaps. The thin and transparent double-sided adhesive film (3), which can be peeled off without leaving scratches or stains on the bonding surface, is combined or interposed, and the entire surface is directly bonded without using any frame or reinforcing plate. The projector (12) installed indoors while variably adjusting the opacity from a transparent state that can be seen through a dimming function by adjusting an applied voltage to a white state that cannot be seen through. Still or being projected video from variously expressed, was supposed to be able to provide a thin image projection screen film with light control function of the liquid crystal utilization can enjoy the outdoors.

しかも、映像を投写しない状況では、液晶利用の調光機能付き薄型映像投写スクリーンフィルムを取り外したり、移動したりすることもなく、設置したそのままの状態で、液晶調光フィルム(2)の特性を生かし電圧を印加して透明にすれば、既設或いは新設の透明ガラス(1)等も薄型透明両面粘着フィルム(3)も透明である為、完全に透視して室内の様子が屋外から見え、例えば室内陳列品などのアピールが行える液晶利用の調光機能付き薄型映像投写スクリーンフィルムである。    In addition, in the situation where no image is projected, the thin film projection screen film with the light control function using the liquid crystal does not need to be removed or moved, and the characteristics of the liquid crystal light control film (2) can be changed as it is installed. If a voltage is applied to make it transparent, the existing or new transparent glass (1) and the thin transparent double-sided adhesive film (3) are also transparent, so that the interior can be seen completely from the outside, and This is a thin image projection screen film with a dimming function using liquid crystal that can appeal to indoor display items.

従来のネマチック液晶を利用した液晶調光フィルムは、その特性上から電圧非印加時に分子が一方向へ規則的に配列されるわけではないので、光を遮断する効果が低下し白色の状態の度合いが不十分で映像を投写して映像用スクリーンとして利用するには充分な明るさ、解像度並びにコントラスト比を得ることができなかったが、「特許文献1」特開2002−040402による処の、強誘電性液晶および反強誘電性液晶からなる高分子組合液晶(PALC)等の発明により充分な明るさ、広視野角度、高解像度、高コントラスト比を実現できるようにはなった。    Due to the characteristics of conventional liquid crystal light control films using nematic liquid crystals, molecules are not regularly arranged in one direction when no voltage is applied, so the effect of blocking light is reduced and the degree of white state is reduced. However, it was not possible to obtain sufficient brightness, resolution and contrast ratio for projecting an image and using it as an image screen due to insufficient image quality. Inventions such as a polymer combination liquid crystal (PALC) comprising a dielectric liquid crystal and an antiferroelectric liquid crystal have made it possible to realize sufficient brightness, a wide viewing angle, high resolution, and a high contrast ratio.

しかしそれとて従来の技術では、液晶調光フィルム(2)をポリビニルブチラート(PVB)やエチレンビニルアセテート(EVA)等の接着樹脂を使用して2枚のガラス板や透明樹脂板に挟み込んで一体化した、非常に重厚かつ高価で、既設の建築物に使用する場合は、該当するガラス部分そのものを工事して取り外し交換し施行しなければならない重作業と多額の費用を必要とする物であった。    However, according to the conventional technology, the liquid crystal light control film (2) is sandwiched between two glass plates or a transparent resin plate using an adhesive resin such as polyvinyl butyrate (PVB) or ethylene vinyl acetate (EVA) to be integrated. When used for existing buildings, it is a heavy, expensive and expensive work that requires the heavy work of constructing, removing, replacing and implementing the relevant glass part itself, and requires a large amount of cost. Was.

また、液晶調光フィルム(2)を、1枚ないし2枚のガラス或いは樹脂板に上述のようなポリビニルブチラート(PVB)やエチレンビニルアセテート(EVA)等の接着樹脂をもって貼り付けて、補強の為の外枠或いはフレーム等を取り付けてパネルとして利用する方法もあるが、これとて既設或いは新設のガラス板に密着させて取り付けることはできないので、間隙に空気の層が介在してしまい、光の透過率と屈折率が一定にならないのと、1枚ないし2枚のガラス板或いは樹脂板等が介在する故、プロジェクターから映像を投写してスクリーンとして利用した場合、既設或いは新設のガラスを経て外側から見ると映像の画質は解像度、明るさ、視野角度、コントラスト比の点で著しく低下してしまっていて実用に耐えられなかった。    Further, the liquid crystal light control film (2) is attached to one or two glass or resin plates with an adhesive resin such as polyvinyl butyrate (PVB) or ethylene vinyl acetate (EVA) as described above to provide reinforcement. There is also a method of attaching an outer frame or frame for use as a panel, but since it can not be attached to an existing or new glass plate in close contact, an air layer intervenes in the gap and light Since the transmittance and refractive index of the glass do not become constant and one or two glass plates or resin plates are interposed, when an image is projected from a projector and used as a screen, it passes through the existing or new glass. When viewed from the outside, the image quality of the image was remarkably reduced in terms of resolution, brightness, viewing angle, and contrast ratio, and was not practical.

仮に液晶調光フィルム(2)を、既設或いは新設のガラス面に直接貼り付ける場合でも、全面を密着させて固定する方法ではなく、周辺部や四隅など一部分のみに両面接着テープ或いは接着樹脂などで取り付ける方法のみであり、いずれの場合にも映像表示用スクリーンとして使用する場合、上述の通り鮮明な画像表現ができず文字などは特に認識しにくかった。    Even if the liquid crystal light control film (2) is directly adhered to the existing or new glass surface, it is not a method of fixing the entire surface in close contact, but using a double-sided adhesive tape or an adhesive resin on only a part of the periphery or four corners. In this case, when the screen is used as an image display screen, a clear image cannot be expressed as described above, and characters and the like are particularly difficult to recognize.

液晶調光フィルム(2)の特性である電圧を印加してフィルム全面を透明化して透視を可能にしたり、電圧の印加を止めて不透明化、つまり白色の状態にして透視できない状態にしてプロジェクターからの投写により映像を表現したりする働きをより効果的かつ実用的に、また廉価で経済的に利用する為に、既設或いは新設の透明ガラス(1)或いは透明合成樹脂製の壁面や窓や扉に対して大がかりな工事や施工、或いは取り替え作業を施すことなく、迅速、簡便かつ安定して全面の貼り付け設置ができ、しかも明るさや広視野角、コントラスト比も充分に確保でき高画質の映像を廉価に提供することと、液晶調光フィルム(2)が透明状態から白色の状態までの間、印加電圧の調節により透明度ならびに白度が連続して可変する事を利用し、映像用スクリーンとして、そこに表現される映像のユニークさと斬新さを合わせて演出し提供することを課題とした。    Applying a voltage, which is a characteristic of the liquid crystal light control film (2), to make the entire surface of the film transparent so that it can be seen through, or to stop the application of voltage to make it opaque, that is, to make it into a white state and make it impossible to see through the projector In order to more effectively and practically use the function of expressing images by projecting images, and at low cost and economically, existing or new transparent glass (1) or transparent synthetic resin walls, windows and doors High-quality images can be quickly, easily and stably stuck on the entire surface without large-scale construction, construction, or replacement work, and also have sufficient brightness, wide viewing angle, and contrast ratio. And that the transparency and whiteness of the liquid crystal light control film (2) can be continuously varied by adjusting the applied voltage from the transparent state to the white state. As a video screen, was an object of the present invention to provide and produce to match the uniqueness and novelty of the video that are represented there.

本考案では、分子が一方向へ規則的に配列されず光を遮断する効果の少ない、つまり電圧を印加しない状態で白色になり不透明となった状態でも映像表示装置としては投写映像の明るさが不足し、解像度が低く、狭視野角度、低コントラスト比となってしまうネマチック液晶などの液晶を原材料に使用したものではなく、明るさも充分にあり、広視野角度、高解像度、高コントラスト比を実現できる、例えば、「特許文献1」特開2002−040402による処の、強誘電性液晶および反強誘電性液晶を40重量%と高分子60重量%以上とからなる高分子組合液晶(PALC)等を使用した薄型の液晶調光フィルム(2)を用いて、既設或いは新設の透明ガラス(1)或いは透明合成樹脂製の壁面や窓や扉に、高透明度を有し、充分に密着し液晶調光フィルム(2)全体を間隙無く安定して接着固定することができ、しかも接着面にキズ跡や汚れを残さず再剥離が可能な薄型透明両面粘着フィルム(3)を「図5」のように合体させ、「図6」のように透明ガラス(1)との間に介在させて、フレームや補強板を使用せずに全面を直接接着し、調光機能により透視可能な透明状態から透視不可能な白色の状態までの間で、不透明度あるいは白度を可変調節しながら、室内に設置されたプロジェクター(12)から静止画或いは動画を投写して様々に表現し、屋外から鑑賞することができることに着目し解決の手段とした。    In the present invention, the molecules are not regularly arranged in one direction, and the effect of blocking light is small, that is, the brightness of the projected image is reduced as a video display device even when it becomes white and opaque when no voltage is applied. Lack of resolution, low resolution, narrow viewing angle, low contrast ratioThe liquid crystal such as nematic liquid crystal is not used as a raw material, but it has sufficient brightness and realizes wide viewing angle, high resolution, high contrast ratio For example, a polymer combination liquid crystal (PALC) comprising 40% by weight of a ferroelectric liquid crystal and an antiferroelectric liquid crystal and 60% by weight or more of a polymer according to Japanese Patent Application Laid-Open No. 2002-040402. Using a thin liquid crystal light control film (2) using, a high degree of transparency and sufficient density on existing or new transparent glass (1) or transparent synthetic resin walls, windows and doors The thin transparent double-sided pressure-sensitive adhesive film (3) that can stably adhere the entire liquid crystal light control film (2) without any gap and that can be re-peeled without leaving scratches or dirt on the bonding surface is shown in FIG. ], And interposed between the transparent glass (1) as shown in FIG. 6 and directly adhered to the entire surface without using a frame or a reinforcing plate. While the opacity or whiteness is variably adjusted from the state to the non-transparent white state, a still image or a moving image is projected from the projector (12) installed in the room to variously express the image, and from the outdoors. Focusing on being able to appreciate, it was a means of solution.

また、映像を投写しない状況では、「図1」の状態の液晶利用の調光機能付き薄型映像投写スクリーンフィルムを取り外したり、移動したりすることもなく、設置したそのままの状態で、液晶調光フィルム(2)の特性を生かし電圧を印加して透明にすれば、既設或いは新設の透明ガラス(1)も薄型透明両面粘着フィルム(3)も透明である為、完全に透視して室内の様子が屋外から見え、例えば室内の陳列品などを屋外に対してアピールできる液晶利用の調光機能付き薄型映像投写スクリーンフィルムを提供することを目的として、上述の液晶調光フィルム(2)に再剥離が可能な薄型透明両面粘着フィルム(3)を「図5」のように合体させたり、透明ガラス(1)との間に介在させて課題の解決を図った。    Also, in a situation where no image is projected, the liquid crystal dimming operation is performed without removing or moving the thin film projection screen film with dimming function using liquid crystal in the state shown in FIG. If the film (2) is made transparent by applying a voltage by making use of the characteristics of the film (2), the existing or new transparent glass (1) and the thin transparent double-sided adhesive film (3) are transparent, so that the room is completely seen through. The liquid crystal light control film (2) is peeled off from the liquid crystal light control film (2) in order to provide a thin image projection screen film with a light control function using a liquid crystal that can be viewed from the outside and, for example, can display indoor display items to the outside. As shown in FIG. 5, a thin transparent double-sided pressure-sensitive adhesive film (3) which can be combined with the transparent glass (1) was used to solve the problem.

本考案の液晶利用の調光機能付き薄型映像投写スクリーンフィルムとは前述の特性を備えた液晶調光フィルム(2)と薄型透明両面粘着フィルム(3)のそれぞれを「図5」のように合体させたもの、或いは「図6」のように、合体或いは透明ガラス(1)等との間に薄型透明両面粘着フィルム(3)が介在している状態のものを言うのであるが、液晶調光フィルム(2)と薄型透明両面粘着フィルム(3)の両方共に薄型で柔軟性を有し、かつ薄型透明両面粘着フィルム(3)は再剥離性を有しながらも充分な接着力をもつので、平面だけに限らず、貼り付け対象物が大曲面の場合でも貼り付けが可能となり、その状態でも上述の様に室内に設置されたプロジェクター(12)から静止画或いは動画を投写して様々に表現し、屋外から鑑賞することができる。    The thin liquid crystal projection screen film with dimming function using the liquid crystal of the present invention combines the liquid crystal dimming film (2) and the thin transparent double-sided adhesive film (3) having the above-mentioned characteristics as shown in FIG. It refers to a state in which a thin transparent double-sided adhesive film (3) is interposed between a united or transparent glass (1) or the like as shown in FIG. Since both the film (2) and the thin transparent double-sided pressure-sensitive adhesive film (3) are thin and flexible, and the thin transparent double-sided pressure-sensitive adhesive film (3) has sufficient adhesive strength while having removability, In addition to flat surfaces, it is possible to paste even when the object to be pasted is a large curved surface. Even in this state, the still image or moving image is projected from the projector (12) installed in the room as described above and variously expressed. And watch from outside Rukoto can.

以上のようにして本考案の課題は解決され、下記の実施例に説明されるような効果を得たが、それらの効果をより有効に利用する為に、例えば街中の商店のショーウインドーや店内を屋外から観覧できるように透明ガラス(1)を外壁に多く使用した既設或いは新設の建築物に使用すれば、液晶調光フィルム(2)と薄型透明両面粘着フィルム(3)からなる液晶利用の調光機能付き薄型映像投写スクリーンフィルムは設置工事費用も製品コストも共に、非常に低価格で供給が可能であり、しかも既設の場合でも建築物の改造や、建築部材を取り替えたりする必要もなく、迅速、簡単、安全かつ廉価に施行取り付けができると言う効果がある。    As described above, the problem of the present invention has been solved, and the effects described in the following embodiments have been obtained.In order to use those effects more effectively, for example, a shop window in a town or a shop window is used. If it is used for existing or new buildings where a large amount of transparent glass (1) is used for the outer wall so that it can be viewed from the outside, the use of liquid crystal comprising a liquid crystal light control film (2) and a thin transparent double-sided adhesive film (3) can be achieved. The thin film projection screen film with optical function can be supplied at very low price, both in installation cost and product cost, and there is no need to remodel buildings or replace building members even if it is already installed, The effect is that the installation can be performed quickly, easily, safely and inexpensively.

室内の様子や陳列物を屋外の人々に通常の通り観覧して欲しい場合には液晶利用の調光機能付き薄型映像投写スクリーンフィルムの印加電圧をオンにして透明な状態にし、室内に設置されたプロジェクター(12)を作動させなければ従来通りの目的を達成でき、液晶利用の調光機能付き薄型映像投写スクリーンフィルムを取り外したり移動したりしなくても、設置したそのままの状態でその効果が得られる事となった。    If you want people outside to view the interior and display objects as usual, turn on the applied voltage of the thin film projection screen film with dimming function using liquid crystal to make it transparent and set it indoors. If the projector (12) is not operated, the conventional object can be achieved, and the effect can be obtained as it is without removing or moving the thin film projection screen film with the dimming function using the liquid crystal. It was done.

透明ガラス(1)等の面に設置された液晶利用の調光機能付き薄型映像投写スクリーンフィルムに目的の或いは好みの映像を投写し屋外の人々にその画像を観覧してもらおうと思えば、液晶利用の調光機能付き薄型映像投写スクリーンフィルムの印加電圧をオフにして不透明つまり白色の状態にしたり、もしくは単巻可変変圧器をもちいて印加電圧を調節し様々な程度の半透明状態にしたりして、室内に設置されたプロジェクター(12)を作動させ、プロジェクターから投写された映像(13)を様々な、充分に明るく、高解像度、広視野角、高コントラスト比で優れた映像を色々な演出効果を伴って披露することができることとなった。    If you want to project a desired or desired image on a thin film projection screen film with a dimming function using liquid crystal installed on a surface such as a transparent glass (1) and have people outdoors see the image, Turn off the applied voltage of the thin film projection screen film with dimming function used to make it opaque, that is, white, or adjust the applied voltage using a single-turn variable transformer to make it variously translucent. Then, the projector (12) installed in the room is operated, and the image (13) projected from the projector is variously rendered to be variously bright, with high resolution, a wide viewing angle, and a high contrast ratio. It can be shown with the effect.

その映像のコンテンツは例えば自店や他社の宣伝であったり、お知らせであったり、認可された情報やニュースであってもよい。またスピーカーを併設して連動して音の効果を提供することも可能であるし、イルミネーションや照明機器と連動して映像と音響と照明のコラボレーションをもって演出する事も可能となり、大きな演出効果を得た。    The content of the video may be, for example, an advertisement of the own store or another company, a notice, or authorized information or news. In addition, it is possible to provide sound effects in conjunction with speakers, and it is also possible to produce collaboration with video, sound and lighting in conjunction with illumination and lighting equipment, resulting in a large production effect Was.

前述のとおり映像表示に適した高分子組合液晶(PALC)を調光液晶層(9)として「図3」のような構造で本考案の液晶調光フィルム(2)を準備した。この場合の液晶調光フィルム(2)の厚みは、透明ポリエチレンテレフタレート(PET)フィルム(7)それぞれが約175マイクロメートル、両外側に合計2枚使用するので合計約350マイクロメートル、透明通電電極(ITO)フィルム(8)それぞれが約30マイクロメートル、調光液晶層(9)の両側に合計2枚使用するので合計約60マイクロメートル、中心に位置する調光液晶層(9)は約25マイクロメートル、したがって液晶調光フィルム(2)の総肉厚は約435マイクロメートルとなる。    As described above, a liquid crystal light control film (2) of the present invention having a structure as shown in FIG. 3 was prepared using a polymer combination liquid crystal (PALC) suitable for image display as a light control liquid crystal layer (9). In this case, the thickness of the liquid crystal light control film (2) is about 175 micrometers for each transparent polyethylene terephthalate (PET) film (7), and about 350 micrometers in total because two films are used on both outer sides. Each of the (ITO) films (8) is about 30 micrometers, and a total of about 60 micrometers because a total of two sheets are used on both sides of the light control liquid crystal layer (9), and the light control liquid crystal layer (9) located at the center is about 25 micrometers. Meters, and thus the total thickness of the liquid crystal light control film (2) is about 435 micrometers.

次に、薄型透明両面粘着フィルム(3)は「図4」のように、中心層には、表面の凹凸が非常にすくなく滑面化された基材の透明ポリエチレンテレフタレート(PET)フィルム(11)が位置しその厚みは約25マイクロメートル。両外側には、硬化後も再剥離性を有し、且つ透明度の高いウレタン系樹脂を適度な接着力と適切な粘着力を実現する為に試行錯誤を何度も繰り返した結果最良となった割合で架橋剤を混合した物を使用し、微低接着力タイプで再剥離性に優れた透明粘着材層(10)を作る為に一定の極めて均等な厚みに、且つむら無く塗布処理を施して、さらに両側の透明粘着材層(10)の両外面の凹凸をも可能な限り滑らかにし、余分な空気や混合物を除去し高透明度を保持する為に光が屈折する要因を除外したものを準備する。片方の透明粘着材層(10)の塗布厚は約25マイクロメートル、両方を合計すると約50マイクロメートルとなり、薄型透明両面粘着フィルム(3)の総肉厚は約75マイクロメートルとなる。    Next, as shown in FIG. 4, the thin transparent double-sided pressure-sensitive adhesive film (3) has a central layer made of a transparent polyethylene terephthalate (PET) film (11) having a very smooth surface without any irregularities on the surface. Is located and its thickness is about 25 micrometers. Both sides have re-peelability even after curing, and the best result was obtained by repeating trial and error many times to realize a suitable adhesive strength and an appropriate adhesive strength with urethane resin with high transparency and high transparency Using a mixture of cross-linking agents in proportions, apply a coating treatment with a uniform and uniform thickness to make a transparent adhesive layer (10) with a very low adhesive strength and excellent removability. Further, irregularities on both outer surfaces of the transparent adhesive material layer (10) on both sides are smoothed as much as possible, and a factor that refracts light in order to remove excess air and a mixture and maintain high transparency is excluded. prepare. The coating thickness of one transparent adhesive layer (10) is about 25 micrometers, and the total thickness of both is about 50 micrometers, and the total thickness of the thin transparent double-sided pressure-sensitive adhesive film (3) is about 75 micrometers.

このようにして作られた薄型透明両面粘着フィルム(3)の透明粘着材層(10)は液晶調光フィルム(2)の最外面にある透明ポリエチレンテレフタレート(PET)フィルム(7)との接着相性もよく、上述のとおり合体させて、或いは適宜使用して「図6」のように、合体或いは透明ガラス(1)等との間に薄型透明両面粘着フィルム(3)が介在している状態にして液晶利用の調光機能付き薄型映像投写スクリーンフィルムとなり、その総肉厚は透明ガラス(1)等の対象物は別にして、約435マイクロメートルと約75マイクロメートルを加えた約510マイクロメートルとなる。まさにフィルムと言う呼称に相応しく、かつ映像表示用スクリーンとしての特性上、鮮明な画像を投写するには好ましい薄さとなった。    The transparent pressure-sensitive adhesive layer (10) of the thin transparent double-sided pressure-sensitive adhesive film (3) thus produced is bonded to the transparent polyethylene terephthalate (PET) film (7) on the outermost surface of the liquid crystal light control film (2). It is also possible to combine them as described above, or to use them as appropriate, so that the thin transparent double-sided adhesive film (3) is interposed between the united or transparent glass (1) as shown in FIG. It becomes a thin image projection screen film with a dimming function using liquid crystal, and its total thickness is about 510 micrometers, which is about 435 micrometers and about 75 micrometers, excluding objects such as transparent glass (1). It becomes. It is exactly the same as the name of film, and because of its characteristics as a screen for displaying images, it is thin enough to project a clear image.

本考案の液晶利用の調光機能付き薄型映像投写スクリーンフィルムの一実施例として、薄型透明両面粘着フィルム(3)の片方の透明粘着材層(10)に液晶調光フィルム(2)を「図5」のように貼り付けるにあたり、気泡や塵が混入したりゆがんだりしないように留意しながら作業を行い、サイズを整えてからしっかりと押さえつけ、透明粘着材層(10)が安定するに必要な一定のエージング期間を設けて常温暗所に保管する。その後、貼り付けようとする既設或いは新設の透明ガラス(1)等の面の埃や汚れを綺麗に取り除き、その面に「図6」のように薄型透明両面粘着フィルム(3)のもう一方の透明粘着材層(10)を、気泡や塵が混入しないように工夫しながら目的の位置に合わせて貼り付ける。    As an example of the thin film projection screen film with a light control function using liquid crystal of the present invention, a liquid crystal light control film (2) is provided on one transparent adhesive layer (10) of a thin transparent double-sided adhesive film (3). When sticking as shown in 5 ”, work while paying attention not to mix or distort bubbles and dust, adjust the size and press down firmly, necessary for the transparent adhesive material layer (10) to stabilize. Store in a dark place at room temperature with a fixed aging period. Then, the dust or dirt on the surface of the existing or new transparent glass (1) to be stuck is removed neatly, and the other surface of the thin transparent double-sided adhesive film (3) as shown in FIG. The transparent pressure-sensitive adhesive layer (10) is adhered to a target position while devising so that air bubbles and dust are not mixed.

或いは、「図2」に表されたように、貼り付けようとする既設の透明ガラス(1)等の面の埃や汚れを綺麗に取り除いた後、薄型透明両面粘着フィルム(3)、液晶調光フィルム(2)の順に同様の留意点を踏まえながら貼り付け作業を行ってもよい。    Alternatively, as shown in FIG. 2, after removing dust and dirt from the surface of the existing transparent glass (1) to be stuck, a thin transparent double-sided adhesive film (3), a liquid crystal tone The sticking operation may be performed in the order of the optical film (2) while keeping the same points in mind.

液晶利用の調光機能付き薄型映像投写スクリーンフィルムは液晶調光フィルム(2)を包含しており、液晶の調光動作には電界を発生させる為の印加電圧の供給が必要となる。「図1」に表したように、その接点となる液晶調光フィルムの電極板(5)には液晶調光フィルムの電源供給ケーブル(6)が固定されていて外部から電力が供給されるが、これら液晶調光フィルムの電極板(5)と液晶調光フィルムの電源供給ケーブル(6)の部位には薄型透明両面粘着フィルム(3)は接着されず、「図7」にあらわしたように、別途に被服の為のカバー(14)をもって保護、隠蔽される。その寸法は最大15ミリメートル幅の例えば樹脂製のもので、周囲の外観に見合った色合いと形状のものを使用し、被服の為のカバー(14)は透明ガラスを支える枠(4)の近辺等に隣接して設置すると外観はよりよくなる。    A thin image projection screen film with a light control function using a liquid crystal includes a liquid crystal light control film (2), and the light control operation of the liquid crystal requires the supply of an applied voltage for generating an electric field. As shown in FIG. 1, a power supply cable (6) for the liquid crystal light control film is fixed to the electrode plate (5) of the liquid crystal light control film serving as the contact point, and power is supplied from the outside. The thin transparent double-sided adhesive film (3) is not bonded to the portions of the electrode plate (5) of the liquid crystal light control film and the power supply cable (6) of the liquid crystal light control film, as shown in FIG. It is protected and concealed separately with a cover (14) for clothing. Its dimensions are up to 15 mm wide, for example made of resin, of a color and shape suitable for the surrounding appearance, and the cover for clothing (14) is near the frame (4) supporting the transparent glass, etc. The appearance will be better if installed next to the.

透明ガラス(1)面に液晶利用の調光機能付き薄型映像投写スクリーンフィルムを貼り終えて設置し液晶調光フィルムの電極板(5)と液晶調光フィルムの電源供給ケーブル(6)の部位を別途に被服の為のカバー(14)で被い、被服の為のカバー(14)を両面粘着テープで透明ガラス(1)面に固定し、液晶調光フィルムの電源供給ケーブル(6)の先端を電源コンセントに接続すれば設置は完了する。    Finish attaching the thin image projection screen film with dimming function using liquid crystal on the transparent glass (1) surface and install it. The electrode plate of liquid crystal dimming film (5) and the power supply cable of liquid crystal dimming film (6) Separately, cover with a cover (14) for clothing, fix the cover (14) for clothing on the transparent glass (1) surface with double-sided adhesive tape, and the tip of the power supply cable (6) of the liquid crystal light control film Connect to the power outlet to complete the installation.

本実施例では、液晶調光フィルムの電源供給ケーブル(6)の中間位置に通電のオンとオフを制御し、印加電圧を連続して調節できる単巻可変変圧器を接続し、液晶利用の調光機能付き薄型映像投写スクリーンフィルムの透明度と不透明度つまり白度を連続して可変的に調節できるようにし、「図7」のように室内に設置されたプロジェクター(12)から液晶利用の調光機能付き薄型映像投写スクリーンフィルムに向けて投写し、プロジェクターから投写された映像(13)を表示した。その際、液晶利用の調光機能付き薄型映像投写スクリーンフィルムの白度を最大にした場合、プロジェクターから投写された映像(13)を透明ガラス(1)の向こう側、つまり屋外から鑑賞したが、非常に広視野角度であり、高コントラスト比で明るく鮮明で解像度も高く、細かい文字などもはっきりと読み取る事ができた。    In the present embodiment, a single-turn variable transformer capable of controlling on and off of the current supply and continuously adjusting the applied voltage is connected to an intermediate position of the power supply cable (6) of the liquid crystal light control film to adjust the use of the liquid crystal. The transparency and opacity, that is, the whiteness of the thin film projection screen film with light function can be continuously and variably adjusted, and the dimming using liquid crystal is performed from a projector (12) installed indoors as shown in FIG. Projected onto a function-equipped thin image projection screen film, and the image (13) projected from the projector was displayed. At that time, when the whiteness of the thin film projection screen film with a light control function using liquid crystal was maximized, the image (13) projected from the projector was viewed from the other side of the transparent glass (1), that is, from outside. It has a very wide viewing angle, a high contrast ratio, and is bright, clear, and has a high resolution. Fine characters can be clearly read.

また液晶利用の調光機能付き薄型映像投写スクリーンフィルムの透明度を最大にして、室内に設置されたプロジェクター(12)の投写を停止すると、同様に屋外から室内が既設或いは新設の透明ガラス(1)だけが存在するかのように透視ができ、液晶利用の調光機能付き薄型映像投写スクリーンフィルムが貼り付けてある事を判別するには近づいて凝視する必要があった。    When the projection of the projector (12) installed indoors is stopped by maximizing the transparency of the thin film projection screen film with a dimming function using liquid crystal, similarly, the indoor or outdoor transparent glass (1) It was necessary to get close to staring to determine that a thin film projection screen film with a light control function using liquid crystal was attached.

加えて単巻可変変圧器の可変電圧を調節すると、液晶利用の調光機能付き薄型映像投写スクリーンフィルムは連続的に異なる程度の半透明状態になり、そこに表現されたプロジェクターから投写された映像(13)を見ると、まるで立体映像やホログラムを見るように空間に映像が浮き上がって見えて、さらに単巻可変変圧器の可変電圧を調節してスクリーンを不透明化或いは透明化へと変化させると、映像は徐々に鮮明な画像に、或いはより不鮮明な画像に変化し非常に斬新かつユニークな映像表現が可能となった。    In addition, when adjusting the variable voltage of the single-turn variable transformer, the thin film projection screen film with dimming function using liquid crystal becomes translucent to different degrees continuously, and the image projected from the projector expressed there Looking at (13), the image appears to float in space as if viewing a stereoscopic image or hologram, and the screen is changed to opaque or transparent by adjusting the variable voltage of the autotransformer. The video gradually changed to a clear image or a blurred image, and a very novel and unique video expression became possible.

尚、本考案の実施に於いて、液晶利用の調光機能付き薄型映像投写スクリーンフィルムが貼り付け設置位置から自然にずり落ちたり、微妙に移動したり、剥がれたりする事は無く、翻って故意に取り外しを意図する場合に於いては、対象物にキズや汚れを残したりすることもなく簡便に撤去できることも確認された。    In the practice of the present invention, a thin image projection screen film with a dimming function using a liquid crystal does not naturally fall, delicately move, or peel off from the mounting position, and it turns on purpose When it was intended to remove the object, it was confirmed that the object could be easily removed without leaving scratches or dirt on the object.

また、本考案の実施に使用した液晶調光フィルム(2)の重量は、上述の厚みで1平方メートルあたり約500グラム、透明粘着材層(10)の接着力は測定の結果、約1N/25mmあり、自然に設置位置がずれたり、移動したりすることの無いバランスが保たれていて、大曲面への貼り付け設置にも問題が無い事が確認できた。The weight of the liquid crystal light control film (2) used in the practice of the present invention was about 500 g per square meter with the above-mentioned thickness, and the adhesive strength of the transparent adhesive layer (10) was measured to be about 1 N / 25 mm. It was confirmed that the balance was maintained so that the installation position did not naturally shift or move, and that there was no problem with pasting and installation on a large curved surface.
