本発明は抗菌層のあるタッチスクリーン及びその製造法に関するもので、特にナノサイズの金属材料をタッチスクリーンの表面に均一かつ緊密に付着させ、抗菌機能のあるタッチスクリーンの製作及びその方法を指したものである。 The present invention relates to a touch screen and a manufacturing method of antimicrobial layer, in particular by depositing a metal material nanosized uniformly and intimately to the surface of the touch screen, pointing to fabrication and method of a touch screen with antibacterial function Is.
ここ数年来、ネットワークの勢い盛んな発展によって電子情報産業の革命をもたらし、電子情報製品の設計及び製造業者は消費者の差し迫ったニーズを満足するため、すでに多くの軽薄短小かつ携帯しやすい製品を開発しており、他に使用者の親和性のニーズに符合するため、更にその各種電子情報製品の入出力介面、または装置に消費者の使用慣習を徹底的に変える設計が行われ、その中の一つの重要な設計がすなわち「タッチスクリーン」である。電子情報製品のタッチスクリーンはその電子情報製品から出力された文字または図形の画面を表すことに用いられるほか、使用者が入力した文字または指令をその電子情報製品に伝送することにも使われ、それと同時にその電子情報製品の出力及び入力装置でもあるので、使用者はその各電子情報製品上でそのタッチスクリーンに現れる文字または図形を見て更に画面の指示によって直接そのタッチスクリーンに現れる仮想のボタンまたは図標（アイコン）を押せば、順調にその電子情報製品を操作制御することができる。使用者に対して言えば、その電子情報製品は使用上極めて便利であり、かつ操作上極めて親和力がある。ソフトウェア設計者に対して言えば、その電子情報製品は極めてフレキシブルに設計された互動式作業プラットフォームを提供し、それによって更に親和力のある互動プログラムを設計することができる。また購買者に対して言えば、その電子情報製品は定額外の入力装置を必要としないので、ほかに入力装置の購入に必要な費用及び予め残す設置空間を節約することができる。 Over the last few years, the vigorous development of the network has revolutionized the electronic information industry, and the design and manufacturers of electronic information products already have many small, light, small, and portable products to satisfy the immediate needs of consumers. In order to meet the needs of other users' compatibility, the design for changing the usage customs of consumers to the input / output interface of various electronic information products or devices has been made. One important design is the “ touch screen”. The touch screen of the electronic information product is used not only to represent the screen of characters or figures output from the electronic information product, but also to transmit the characters or commands entered by the user to the electronic information product, At the same time, since it is also an output and input device of the electronic information product, the user looks at the characters or figures that appear on the touch screen on each electronic information product, and further displays virtual buttons that appear directly on the touch screen by instructions on the screen Alternatively, if a mark (icon) is pressed, the electronic information product can be smoothly controlled. For the user, the electronic information product is very convenient in use and very compatible in operation. For software designers, the electronic information product provides an interactive work platform that is designed to be very flexible, thereby allowing more interactive programs to be designed. In addition, to the purchaser, the electronic information product does not require an input device that is not a fixed amount, so that it is possible to save the cost necessary for purchasing the input device and the installation space left in advance.
そのために、ここ数年来、タッチスクリーンが設けられる各種電子情報製品はすでに多くの公共場所に幅広く使用され、例えば学校、デパート、病院、空港、汽車駅等で多くの不特定使用者に情報の問い合わせ及びガイダンスを行うことに供され、使用者のために操作が簡単便利でかつ親和力のある入出力装置を提供し、このほか、それに取り付けられるソフトウェアの設計が適切である場合、それにより更に効果的に多くの使用者が公共場所で遭遇する多くの問題及び困りごとを迅速に解決することができる。ところが、玉に瑕というか、この種のタッチスクリーンが設けられる電子情報製品は公共場所に設置され、多くの使用者の操作に供されるので、発生可能な唯一の欠点は細菌が伝播する媒介物に極めてなりやすく、公共衛生及び人々の健康の大きな脅威になる。そのために、如何にして公共場所中の各種電子情報製品のタッチスクリーンの清潔衛生を確保するかが、各公共場所の主管機関の特に注意するべき、かつ軽易に見落とせない重要な課題になっている。 For this reason, various electronic information products with touch screens have been widely used in many public places for the past several years. Provide an input / output device that is easy to operate and has a good affinity for the user, and is more effective if the software attached to it is properly designed. In addition, many problems and troubles that many users encounter in public places can be solved quickly. However, since the electronic information products that are equipped with this kind of touch screen are installed in public places and are operated by many users, the only disadvantage that can occur is the transmission of bacteria. It is extremely prone to things and is a major threat to public health and people's health. Therefore, how to ensure the cleanliness and hygiene of the touch screens of various electronic information products in public places is an important issue that should be paid special attention to the main authority of each public place and cannot be easily overlooked. Yes.
タッチスクリーンがすでに公共場所での細菌を伝播する媒介物になることに鑑み、多くの電子情報製品の設計及び製造業者はこの潜在的危機を解決するため、尽力して細菌抑制能力のあるタッチスクリーンを研究開発し、その方法はタッチスクリーンの上に細菌抑制能力のある組成物を塗布するが、一般に、現在の各電子情報製品の業者が使用する細菌抑制組成物の多くは有機物から構成され、それら有機物がタッチスクリーンの表面に塗布されると細菌の生長を抑制することができるが、それらの融点または沸点が低いので極めて容易に蒸発または分解してしまい、そのために長期間の細菌抑制効果がなく、更にその材料には一般に毒性があるので、人間が直接接触する製品に応用または塗布することに適しない。他の業者は近年来かなり流行っている酸化チタン触媒を利用して抑菌または抗菌処理を行っているが、それはＵＶ光源の下で行わなければ光催化及び殺菌作用がなく、一般の室内の光源でのＵＶ光線はかなり微弱であるので、それに発生する抗菌効果はあまり理想でない。 In view of the fact that touchscreens are already a mediator for the transmission of bacteria in public places, many electronic information product designs and manufacturers are working hard to resolve this potential crisis with a touchscreen capable of controlling bacteria. Research and development, and the method is to apply a composition capable of inhibiting bacteria on a touch screen, but in general, many of the presently used bacteria inhibiting compositions are composed of organic matter, When these organic substances are applied to the surface of the touch screen, the growth of bacteria can be suppressed, but since their melting point or boiling point is low, they evaporate or decompose very easily, and thus have a long-term bacteria suppression effect. In addition, the material is generally toxic and is not suitable for application or application to products in direct human contact. Other vendors have been using antibacterial or antibacterial treatments using titanium oxide catalysts that have been quite popular in recent years, but they have no photo-acceleration and bactericidal action unless performed under a UV light source. Since the UV light at is very weak, the antibacterial effect that occurs in it is not very ideal.
そのために、いかにして適切な抑菌材料を選択し、並びに新しい製造過程を設計して抗菌機能を兼ねたタッチスクリーンを製造し、そのタッチスクリーンの抗菌特性及び応用領域を向上するのが本発明のここで検討する重要な課題である。
前述周知のタッチスクリーンがそれぞれ長くから存在する問題に鑑み、発明人は長年の実務経験及び研究心得によって、本発明の抗菌層のあるタッチスクリーン及びその製造法を開発した。
