Description
本発明は調光ミラー装置に関し、より具体的には、残像効果を利用した調光ミラー装置に関する。 The present invention relates to a light control mirror device, and more specifically to a light control mirror device using an afterimage effect.
従来から、鏡状態と透明状態とを切り替えることのできる調光ミラーについて、研究開発が進められている。 Conventionally, research and development has been conducted on a dimming mirror capable of switching between a mirror state and a transparent state.
例えば特許文献１（特開２００５−２７４６３０号公報）においては、全固体型調光ミラー光スイッチ及びその製造方法等を提供すべく、「透明な基材に多層薄膜を形成した調光ミラー光スイッチ素子であって、基材の上に、イオンストレージ層、固体電解質層、プロトン注入層、及びマグネシウム・ニッケル系合金薄膜を用いた調光ミラー層を形成したことを特徴とする全固体型調光ミラー光スイッチ素子、透明な基材に多層薄膜を形成した調光ミラー光素子を製造する方法であって、基材の上に、イオンストレージ層、固体電解質層、プロトン注入層、及びマグネシウム・ニッケル系調光ミラー層を積層することを特徴とする全固体型調光ミラー光スイッチ素子の製造方法、及びその応用製品。」が提案されている。 For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-274630), “a dimming mirror optical switch in which a multilayer thin film is formed on a transparent substrate” is provided in order to provide an all-solid-state dimming mirror optical switch and a manufacturing method thereof. An all-solid-state light control device comprising an ion storage layer, a solid electrolyte layer, a proton injection layer, and a light control mirror layer using a magnesium-nickel alloy thin film on a substrate. Mirror light switch element, method of manufacturing dimming mirror optical element in which multilayer thin film is formed on transparent substrate, ion storage layer, solid electrolyte layer, proton injection layer, and magnesium / nickel on substrate A manufacturing method of an all-solid-state dimming mirror optical switch element characterized by laminating a system dimming mirror layer and its application product have been proposed.
また、例えば特許文献２（特開２００７−３０１７７８号公報）においては、界面の構造を制御してスイッチングの耐久性を高めた調光ミラーを提供すべく、「透明な基材に、多層薄膜を形成した薄膜素子であり、水素を含むガスにより鏡状態から透明状態に変化し、また、酸素を含むガスにより透明状態から鏡状態に変化する調光材料において、多層薄膜が、調光層、バッファ層、及び触媒層から成ることを特徴とする調光ミラー材料、及び該調光ミラー材料を用いて調光機能を付加した調光ミラー機能を有する物品。」が提案されている。 Further, for example, in Patent Document 2 (Japanese Patent Application Laid-Open No. 2007-301778), “a multilayer thin film is formed on a transparent base material in order to provide a dimming mirror having an improved switching durability by controlling the interface structure. A thin film element formed in a light control material that changes from a mirror state to a transparent state by a gas containing hydrogen, and changes from a transparent state to a mirror state by a gas containing oxygen. A light control mirror material comprising a layer and a catalyst layer, and an article having a light control mirror function to which a light control function is added using the light control mirror material have been proposed.
更に、特許文献３（特開２００４−２５８４００号公報）においては、マグネシウム・ニッケル系合金薄膜などの希土類金属の水素化物からなる薄膜の実用的な新たな用途を提供すべく、「マグネシウム・ニッケル系合金薄膜などの希土類金属の水素化物を含む調光ミラー層２０を、情報表示部としての液晶パネル部１１の前側に配置した。従って、印加する電圧を制御するのみで、透明状態とすることにより、情報表示部としての液晶パネル部１１を通常の情報表示媒体として使用できると共に、該調光ミラー層２０を鏡面状態とすることにより、鏡として使用することができる。」との提案がなされている。 Further, in Patent Document 3 (Japanese Patent Application Laid-Open No. 2004-258400), in order to provide a new practical application of a thin film made of a hydride of a rare earth metal such as a magnesium / nickel alloy thin film, A dimming mirror layer 20 containing a rare earth metal hydride such as an alloy thin film is disposed on the front side of the liquid crystal panel section 11 as an information display section, so that it can be made transparent only by controlling the applied voltage. The liquid crystal panel unit 11 as the information display unit can be used as a normal information display medium, and can be used as a mirror by setting the light control mirror layer 20 to a mirror surface state. ” Yes.
しかし、特許文献１に開示されている全固体型調光ミラー光スイッチ素子は、光ファイバー通信に用いる光スイッチ素子に関するものであり、特許文献２及び特許文献３に開示されている調光ミラーは、透明な状態と鏡の状態がスイッチングできる従来の調光ミラーに関するものに過ぎない。 However, the all-solid-state dimming mirror optical switch element disclosed in Patent Document 1 relates to an optical switch element used for optical fiber communication, and the dimming mirrors disclosed in Patent Document 2 and Patent Document 3 are It merely relates to a conventional dimming mirror that can switch between a transparent state and a mirror state.
これに対し、本発明者は、従来に無い新規な方法で制御することによって新規な機能を有する調光ミラー装置を実現することができないか鋭意検討した結果、残像効果を利用することができれば付加価値のある調光ミラー装置を得ることができることを見出し、本発明を完成するに至った。即ち、本発明の目的は従来に無い新規な機能を有する調光ミラー装置の提供にある。 On the other hand, the present inventor has eagerly studied whether or not a dimming mirror device having a novel function can be realized by controlling by a novel method that has not been conventionally used. The inventors have found that a valuable dimming mirror device can be obtained, and have completed the present invention. That is, an object of the present invention is to provide a dimming mirror device having a novel function that has not been found in the past.
本発明者は上記目的を達成すべく、印加電圧のオン／オフ又は極の切換えにより鏡面状態又は透明状態に変化する調光ミラー層と、前記印加電圧のオン／オフ又は極の切換えをそれぞれ所定の時間間隔で可変的に行う制御回路と、を具備し、前記透明状態の時間を人の目の時間分解能付近の残像効果を伴う時間とすることによって、鏡面状態の前記調光ミラー層に映る像と、透明状態の前記調光ミラー層を透過して見える背後の像とが、残像効果によって二重に見えること、を特徴とする調光ミラー装置を提供する。 In order to achieve the above object, the present inventor predetermines a dimming mirror layer that changes to a mirror surface state or a transparent state by turning on / off or switching the applied voltage, and switching the applied voltage on / off or switching the pole. And a control circuit that variably performs at a time interval of, and by making the time in the transparent state a time with an afterimage effect in the vicinity of the time resolution of the human eye, it is reflected in the light control mirror layer in the mirror state Provided is a light control mirror device characterized in that an image and a back image that appears to be transmitted through the light control mirror layer in a transparent state appear double due to an afterimage effect.
このような構成を有する本発明の調光ミラー装置によれば、人の目の残像効果により、調光ミラー層の第一の面（前面）側からみた場合に、鏡面状態となった調光ミラー層の前面に映る前面側の像と、透明状態となった調光ミラー層を透過して見える第二の面（後面）側の像とが、二重写しとなって見える。 According to the dimming mirror device of the present invention having such a configuration, the dimming in a mirror state when viewed from the first surface (front surface) side of the dimming mirror layer due to the afterimage effect of human eyes. An image on the front surface reflected on the front surface of the mirror layer and an image on the second surface (rear surface) side that appears to be transmitted through the dimming mirror layer in a transparent state appear as a double copy.
また、制御回路によって印加電圧のオン／オフをそれぞれ所定の時間間隔で可変的に行うことによって、前面に映るものが、前面側の像から後面側の像に、又は、後面側の像から前面側の像に、次第に切り替わっていく。 In addition, the control circuit variably turns on and off the applied voltage at predetermined time intervals, so that what appears on the front surface changes from the front side image to the rear side image, or from the rear side image to the front side. It gradually switches to the side image.
上記の本発明の調光ミラー装置においては、前記透明状態の時間が２０ｍｓ〜２００ｍｓであること、更には、５０ｍｓ〜１００ｍｓであることが好ましい。 In the dimming mirror device of the present invention, the time for the transparent state is preferably 20 ms to 200 ms, and more preferably 50 ms to 100 ms.
このような構成を有する本発明の調光ミラー装置によれば、上記のような作用効果をより確実に得ることができる。 According to the dimming mirror device of the present invention having such a configuration, the above-described operational effects can be obtained more reliably.
上記の本発明の調光ミラー装置においては、前記調光ミラー層の背後（即ち、調光ミラー層の後面側）に設けられた光源を含むこと、が好ましい。 In the dimming mirror device of the present invention, it is preferable to include a light source provided behind the dimming mirror layer (that is, the rear surface side of the dimming mirror layer).
このような構成を有する本発明の調光ミラー装置によれば、制御回路によって印加電圧のオン／オフをそれぞれ所定の時間間隔で可変的に変化させることによって、調光ミラーの後面側に位置する光源からの光をまぶしく感じず、かつ、暗い場所でも使用することのできる鏡を実現することができる（特に透明状態の時間が５０ｍｓ以下）。 According to the dimming mirror device of the present invention having such a configuration, the control circuit is located on the rear surface side of the dimming mirror by variably changing the on / off of the applied voltage at predetermined time intervals. It is possible to realize a mirror that does not feel light from the light source and can be used even in a dark place (particularly, the time for the transparent state is 50 ms or less).
本発明は、上記の本発明の調光ミラー装置を含むことを特徴とする表示装置にも関する。かかる表示装置としては、例えば、液晶表示装置を含む携帯電話及びタブレット型端末機器等が挙げられる。 The present invention also relates to a display device including the light control mirror device of the present invention.

以下、図面を参照しながら本発明の調光ミラー装置の代表的な実施形態について詳細に説明するが、本発明はこれらのみに限定されるものではない。なお、以下の説明では、同一または相当部分には同一符号を付し、重複する説明は省略する場合がある。また、図面は、本発明を概念的に説明するためのものであるから、表された各構成要素の寸法やそれらの比は実際のものとは異なる場合もある。 Hereinafter, typical embodiments of the light control mirror device of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to these. In the following description, the same or corresponding parts are denoted by the same reference numerals, and redundant description may be omitted. Further, since the drawings are for conceptually explaining the present invention, the dimensions and ratios of the components shown may be different from the actual ones.
図１は、本発明の調光ミラー装置の一実施形態の構成を示す概略図であり、図２は、図１に示す調光ミラー装置１における制御回路による印加電圧のオン／オフの切換えの時間間隔の一例を示すグラフである。 FIG. 1 is a schematic diagram showing a configuration of an embodiment of a dimming mirror device of the present invention, and FIG. 2 is a diagram illustrating switching of on / off of an applied voltage by a control circuit in the dimming mirror device 1 shown in FIG. It is a graph which shows an example of a time interval.
本実施形態の調光ミラー装置１は、図１に示すように、印加電圧のオン／オフにより鏡面状態又は透明状態に変化する調光ミラー層２と、印加電圧のオン／オフをそれぞれ所定の時間間隔で可変的に切換可能な制御回路３と、を具備する。また、調光ミラー層２の後面側には光源４が設置されており、電源コード５が接続されている。 As shown in FIG. 1, the dimming mirror device 1 of the present embodiment includes a dimming mirror layer 2 that changes to a mirror surface state or a transparent state according to on / off of the applied voltage, and a predetermined on / off state of the applied voltage. And a control circuit 3 that can be variably switched at time intervals. A light source 4 is installed on the rear side of the light control mirror layer 2 and a power cord 5 is connected thereto.
この調光ミラー装置１においては、図２に示すように、印加電圧オンの鏡面状態の時間ｔａ及び印加電圧オフの透明状態の時間ｔｂのうち、透明状態の時間ｔｂを人の時間分解能（５０ｍｓ〜１００ｍｓ）と同等かもしくはより短く設定することが最大の特徴である。 In the dimming mirror device 1, as shown in FIG. 2, the transparent time tb of the mirror surface time ta with the applied voltage on and the transparent time tb with the applied voltage off is set to a human time resolution (50 ms). It is the greatest feature that it is set to be equal to or shorter than 100 ms).
このように設定することによって、鏡面状態の調光ミラー層２に映る像と、透明状態の調光ミラー層２を透過して見える背後の像とが、残像効果によって二重に見えるという従来に無い作用効果を得ることができる。 By setting in this way, an image reflected on the mirror-like light control mirror layer 2 and a back image that can be seen through the light-control light mirror layer 2 in a transparent state can be doubled by the afterimage effect. There is no effect.
ここで、調光ミラー層２としては、従来公知の調光ミラー層を用いることができ、例えばエレクトロクロミック式の調光ミラーでもガスクロミック式の調光ミラーを用いることができる。 Here, as the light control mirror layer 2, a conventionally known light control mirror layer can be used. For example, an electrochromic light control mirror or a gas chromic light control mirror can be used.
また、オン／オフの切換えを可変的に（即ち、透明状態の時間ｔａ及び鏡面状態の時間ｔｂの長さを変更可能に）制御する制御回路３としては、従来公知の制御回路を用いることができ、例えばフリップフロップ回路等を用いて構成することができる。 In addition, as the control circuit 3 that variably controls the on / off switching (that is, the length of the transparent state time ta and the specular state time tb can be changed), a conventionally known control circuit can be used. For example, a flip-flop circuit or the like can be used.
透明状態の時間ｔｂは、上記のとおり、２０ｍｓ〜２００ｍｓ、更には５０ｍｓ〜１００ｍｓあればよく、特にまぶしくなく明るい鏡面状態にする場合には、５０ｍｓ以下であること、が好ましい。他方、鏡面状態の時間ｔａは、例えば１００〜２００ｍｓであればよい。 As described above, the time tb in the transparent state may be 20 ms to 200 ms, more preferably 50 ms to 100 ms, and is preferably 50 ms or less particularly in a bright mirror surface state. On the other hand, the mirror state time ta may be, for example, 100 to 200 ms.
なお、図３は、本発明の調光ミラー装置における制御回路による印加電圧の極の切換えの時間間隔の一例を示すグラフである。調光ミラー層の種類によっては、このように印加電圧の極の切換えによって本発明を実現することができる。 FIG. 3 is a graph showing an example of the time interval for switching the poles of the applied voltage by the control circuit in the dimming mirror device of the present invention. Depending on the type of the light control mirror layer, the present invention can be realized by switching the poles of the applied voltage in this way.
以上、本発明の調光ミラー装置の一実施形態について概略的に説明したが、本発明はこれらのみに限定されるものではなく、特許請求の範囲に記載の技術的思想の範囲であらゆる設計変更が可能であり、これら設計変更された態様も当然に本発明に含まれる。 As mentioned above, although one Embodiment of the light control mirror apparatus of this invention was demonstrated roughly, this invention is not limited only to these, All the design changes are in the range of the technical idea as described in a claim.
