Description

本発明は、白黒の液晶を使用してカラフルな表示物を点滅させることができる点滅表示体に係り、キーホルダー用又はアクセサリー用液晶表示装置に関する。 The present invention relates to a blinking display body capable of blinking colorful display objects using black and white liquid crystal, and relates to a liquid crystal display device for a key holder or an accessory.

従来、液晶パネルを利用した広告板として特許文献１に記載された広告板が提案されている。この広告板は、デザイン化されていないセグメント電極を内蔵する液晶パネルを内蔵用ケースに設置し、この内蔵用ケース内に光源を配備し、この光源で液晶パネルを照射するものである。   Conventionally, the advertising board described in patent document 1 is proposed as an advertising board using a liquid crystal panel. In this advertising board, a liquid crystal panel having a segment electrode that is not designed is installed in a built-in case, a light source is provided in the built-in case, and the liquid crystal panel is irradiated with the light source.

また液晶を点滅表示する液晶広告媒体が引用文献２に記載されている。この広告媒体は、電極付きの基板間に液晶を挟持した液晶パネルを点滅させ、この液晶パネルの前面に図柄層を設けたものである。そして、図柄層の周辺を白黒に点滅させることで、人目を惹く広告媒体とするものである。   Also, a liquid crystal advertising medium that flashes and displays liquid crystal is described in Patent Document 2. In this advertising medium, a liquid crystal panel having liquid crystal sandwiched between substrates with electrodes is blinked, and a design layer is provided on the front surface of the liquid crystal panel. Then, by flashing the periphery of the design layer in black and white, the advertisement medium is attractive.

特表２００３−５０７７５１号公報Japanese translation of PCT publication No. 2003-507751 特開平８−１５６６５号公報JP-A-8-15665

液晶を使用した特許文献１の広告板は、点滅する液晶表示パネルの前面に、偏光フィルムや屈折フィルムを定着して広告表示部を設けることで、この液晶表示パネルの点滅に伴って、広告表示部の周囲や文字・図柄等の明暗が交互に変わるようにしている。更に、液晶表示パネルの裏側に配置した光源で液晶パネルを照らすことで、広告表示を鮮明に表示しようとするものである。   The advertising board of patent document 1 using a liquid crystal is provided with an advertising display unit by fixing a polarizing film or a refractive film on the front surface of a flashing liquid crystal display panel. The surroundings of the part and the light and darkness of characters and designs are changed alternately. Further, the advertisement display is clearly displayed by illuminating the liquid crystal panel with a light source disposed on the back side of the liquid crystal display panel.

ところが、この広告板では、液晶表示パネルの前面に、広告内容を示す広告表示部を設けているので、この広告表示部は、液晶パネルの光が透過するように設ける必要がある。そのため、偏光フィルムや不透明フィルムに広告表示部を設けたり、液晶表示パネルのスクリーン表面に直接表示したりする手段が採用されているが、いずれにしても、広告表示部は、液晶表示パネルによる背面からの光を透過して表示するので、特許文献１の広告板は、通常の印刷物をそのままの色彩や明度で表示することは困難であった。しかも、液晶パネルの照度が極めて低いので、昼間に使用する場合は、液晶表示パネルの裏側に配置した光源を利用する必要がある。このため、広告表示部から光源までにある程度の距離が必要となり、広告板の厚みが極めて厚くなる不都合もあった。   However, since this advertisement board is provided with an advertisement display section showing advertisement contents on the front surface of the liquid crystal display panel, it is necessary to provide the advertisement display section so that light from the liquid crystal panel can be transmitted. For this reason, means for providing an advertisement display part on a polarizing film or an opaque film or displaying directly on the screen surface of the liquid crystal display panel is adopted. Therefore, it is difficult for the advertising board of Patent Document 1 to display a normal printed matter with the same color and lightness. Moreover, since the illuminance of the liquid crystal panel is extremely low, it is necessary to use a light source disposed on the back side of the liquid crystal display panel when used in the daytime. For this reason, a certain distance is required from the advertisement display unit to the light source, and there is a disadvantage that the thickness of the advertisement board becomes extremely thick.

一方、特許文献２の広告媒体は、図柄層の後面に配した液晶パネルの点滅に伴って図柄層の周囲を白黒に点滅させ、あるいは図柄層自体の色や表示の濃さを変化させるものである。例えば、図柄層を形成するシートに遮光性シートを用いた場合は、図柄層の周囲の色が液晶パネルの点滅に伴って変化する広告になる。ところが、遮光性シートを用いて、図柄層の周囲の色が変化するものでは、常に図柄層が表出しており周囲の限られた部分のみが変化し、しかも昼間ではこの液晶パネルの照度が低いので、広告媒体として人目を惹く効果はあまり期待できない。   On the other hand, the advertising medium of Patent Document 2 blinks around the design layer in black and white as the liquid crystal panel disposed on the rear surface of the design layer flashes, or changes the color of the design layer itself and the display density. is there. For example, when a light-shielding sheet is used as the sheet for forming the symbol layer, the advertisement changes in accordance with the blinking of the liquid crystal panel. However, if the surrounding color of the design layer changes using a light-shielding sheet, the design layer always appears and only a limited portion of the surroundings changes, and the illuminance of this liquid crystal panel is low in the daytime. Therefore, it cannot be expected to attract a lot of attention as an advertising medium.

また、特許文献２において、また、図柄層を形成するシートに半透過性シートを用いると、周囲の変化と共に、図柄層の色や表示の濃さも変化するようになる。ところが、半透過性シートを用いて図柄層の色や表示の濃さも変化するように設けるには、偏光シートや屈折シートなどを用いなければ、図柄層を効果的に変化させることはできず、その分、図柄層の構成が複雑になってしまう。また、いずれのシートを用いたにしても、図柄層の裏面に配した液晶パネルの点滅によって図柄層を表示する構成であるから、液晶パネルの照度が低いために、昼間に十分な広告効果を得ることはできない。   Further, in Patent Document 2, when a semi-permeable sheet is used as a sheet for forming a symbol layer, the color of the symbol layer and the display density change as the surroundings change. However, in order to change the color of the design layer and the darkness of the display using a translucent sheet, the design layer cannot be effectively changed unless a polarizing sheet or a refractive sheet is used. Accordingly, the structure of the symbol layer becomes complicated. In addition, no matter which sheet is used, the design layer is displayed by the flashing of the liquid crystal panel placed on the back side of the design layer. I can't get it.

そこで本発明は、上述の課題を解消すべく創出されたもので、点滅する白黒の液晶パネルを利用して、昼間でもカラフルで効果的な表示効果が得られ、しかも極めてシンプルでスリムな構成でありながら、表示物の表示手段を自由に選択することができるキーホルダー用又はアクセサリー用液晶表示装置の提供を目的とするものである。 Therefore, the present invention was created to solve the above-mentioned problems. By using a blinking black and white liquid crystal panel, a colorful and effective display effect can be obtained even in the daytime, and the configuration is extremely simple and slim. However, an object of the present invention is to provide a liquid crystal display device for a key ring or an accessory that can freely select a display means for a display object.

本発明の手段は、表示物２の表示面に液晶パネル１を重ね合せ、該液晶パネル１通電時に液晶パネル１で表示面を遮蔽し、液晶パネル１無通電時に透明になった液晶パネル１を通して表示面を表示させ、液晶パネル１の点滅に伴って表示物２の表示面が点滅して見えるように設けたキーホルダー用又はアクセサリー用液晶表示装置において、該液晶表示装置の表示面側から液晶パネル１、表示物２、制御基盤３の順序で透明な収納ケース５内に収納すると共に、該液晶パネルに通電する太陽電池からなる電源４を収納ケース５内に収納し、表示物は光反射性のシート又はフィルムに印刷された表示面を有するものとし、液晶パネル１の表面を覆う透明なエポキシ樹脂製の被覆材６を収納ケース５に充填して収納ケース５を密閉し、液晶パネル１の表面を覆う透明なエポキシ樹脂製の被覆材６を通して光反射性の表示物２の表示面で光が反射し、光の届く場所において長期間表示面が点滅しているかの如く表示するようにしたことにある。 According to the means of the present invention, the liquid crystal panel 1 is overlaid on the display surface of the display object 2, the display surface is shielded by the liquid crystal panel 1 when the liquid crystal panel 1 is energized, and the liquid crystal panel 1 passes through the liquid crystal panel 1 that is transparent when not energized. In a liquid crystal display device for a key holder or accessory provided so that a display surface is displayed and the display surface of a display object 2 appears to blink as the liquid crystal panel 1 blinks, the liquid crystal panel from the display surface side of the liquid crystal display device 1. The display object 2 and the control board 3 are stored in the transparent storage case 5 in this order, and the power source 4 composed of a solar cell energizing the liquid crystal panel is stored in the storage case 5. The display object is light-reflective. The display case printed on the sheet or film is filled with a transparent epoxy resin coating 6 covering the surface of the liquid crystal panel 1 and the storage case 5 is hermetically sealed. Light is reflected by the display surface of the light reflective display object 2 through the coating material 6 made of transparent epoxy resin covering the surface of, as long-term display surface in the reach of the light is displayed as if flashing It is to have done.

本発明により、液晶パネル１無通電時に透明になった液晶パネル１を通して表示面を表示させ、液晶パネル１の点滅に伴って表示物２の表示面が点滅して見えるように設けたことで、昼間でもカラフルで効果的な表示効果が得られる。また、表示物２の表示面に液晶パネル１を重ね合せるだけでよいので、極めてシンプルでスリムな構成にすることができる。しかも、表示物２は透明になった液晶パネル１を通して表示されるので、表示物の表示手段も自由に選択することができる。 According to the present invention, the display surface is displayed through the liquid crystal panel 1 that is transparent when the liquid crystal panel 1 is not energized, and the display surface of the display object 2 appears to blink as the liquid crystal panel 1 blinks. A colorful and effective display effect can be obtained even in the daytime. Moreover, it is only Ru superimposing the liquid crystal panel 1 to the display surface of the display object 2 can be made very simple and slim structure. Moreover, since the display object 2 is displayed through the transparent liquid crystal panel 1, display means for the display object can be freely selected.

また、各構成部材を収納ケース５内に収納し、液晶パネル１の表面を覆う透明なエポキシ樹脂製の被覆材６で収納ケース５を閉じるように設けているので、極めてシンプルでスリムな構成にすることができる。この結果、本発明点滅表示装置を、キーホルダーやアクセサリー等の小物用品に用いることが可能である。   In addition, since each component is stored in the storage case 5 and the storage case 5 is closed with a transparent epoxy resin covering material 6 covering the surface of the liquid crystal panel 1, the configuration is extremely simple and slim. can do. As a result, the blinking display device of the present invention can be used for small articles such as key holders and accessories.

更に、電源４として太陽電池を用い、前記被覆材６を透明なエポキシ樹脂とし、該被覆材６を透明な収納ケース５内に充填して収納ケース５を密閉することで、極めて密封効果が高く、しかも電源４の交換がなくても、光の届く場所において長期間点滅するキーホルダー用又はアクセサリー用液晶表示装置を提供することができる。 Furthermore, a solar cell is used as the power source 4, the covering material 6 is made of a transparent epoxy resin, and the covering material 6 is filled in the transparent housing case 5 to seal the housing case 5, so that the sealing effect is extremely high. In addition, it is possible to provide a liquid crystal display device for a key holder or an accessory that blinks for a long time in a place where light reaches even if the power source 4 is not replaced.

光反射性のシート又はフィルムに表示面を印刷することで、液晶パネル１が透明になったときに、このシート又はフィルム自体の反射効果によって、表示物２の表示面をより効果的に表示させることができる。しかも、周囲が明るいほど効果的な表示効果が得られる。   By printing the display surface on a light-reflective sheet or film, when the liquid crystal panel 1 becomes transparent, the display surface of the display object 2 is displayed more effectively by the reflection effect of the sheet or film itself. be able to. In addition, the brighter the surroundings, the more effective display effect can be obtained.

このように本発明によると、点滅する白黒の液晶パネルを利用して、昼間でもカラフルで効果的な表示効果が得られ、しかも極めてシンプルでスリムな構成でありながら、表示物の表示手段を自由に選択することができるといった有益な種々の効果を奏するものである。   As described above, according to the present invention, a blinking black and white liquid crystal panel can be used to provide a colorful and effective display effect even in the daytime. There are various beneficial effects that can be selected.

本発明の最良の形態は、表示物２の表示面に液晶パネル１を重合する。該液晶パネル１通電時に液晶パネル１で表示面を遮蔽し、液晶パネル１無通電時に透明になった液晶パネル１を通して表示面を表示させる。表示物２は、光反射性のシート又はフィルムに印刷されている。表示物２と液晶パネル１と制御基盤３と太陽電池とを透明なエポキシ樹脂製の収納ケース５内に収納する。液晶パネル１の表面を覆う透明なエポキシ樹脂製の被覆材６で収納ケース５を密封することで、当初の目的を達成するものである。   In the best mode of the present invention, the liquid crystal panel 1 is polymerized on the display surface of the display object 2. The liquid crystal panel 1 shields the display surface when the liquid crystal panel 1 is energized, and the liquid crystal panel 1 that is transparent when the liquid crystal panel 1 is not energized displays the display surface. The display object 2 is printed on a light-reflective sheet or film. The display object 2, the liquid crystal panel 1, the control board 3, and the solar cell are stored in a storage case 5 made of transparent epoxy resin. The original purpose is achieved by sealing the storage case 5 with a transparent epoxy resin coating 6 covering the surface of the liquid crystal panel 1.

本発明は、点滅する液晶パネル１を用いて表示物２に周囲の注意を惹くように表示するキーホルダー用又はアクセサリー用液晶表示装置である。 The present invention is a liquid crystal display device for a key holder or an accessory that displays a flashing liquid crystal panel 1 so as to attract the attention of the surroundings to the display object 2.

本発明小物用表示装置の主要構成は、液晶パネル１、表示物２、制御基盤３、電源４にて構成され、制御基盤３と電源４は、液晶パネル１を点滅させるものである。通電時の液晶パネル１は、液晶がパネル前面を黒く表示し、無通電時に透明になる液晶パネル１を用いる。   The main structure of the display device for small items of the present invention is composed of a liquid crystal panel 1, a display object 2, a control board 3, and a power source 4. The control board 3 and the power source 4 blink the liquid crystal panel 1. The liquid crystal panel 1 when energized uses the liquid crystal panel 1 in which the liquid crystal displays the front face of the panel in black and becomes transparent when de-energized.

点滅する液晶パネル１は、表示物２の表示面に重ね合せる。そして、該液晶パネル１通電時に、黒く表示された液晶パネル１で表示面を遮蔽し、液晶パネル１無通電時に透明になった液晶パネル１を通して表示面を表示させるものである。このように、液晶パネル１の点滅に伴って表示物２の表示面で光が点滅して見えるようにしている。 The liquid crystal panel 1 to be blinking, Ru overlapping the display surface of the display object 2. When the liquid crystal panel 1 is energized, the display surface is shielded by the liquid crystal panel 1 displayed in black, and the display surface is displayed through the liquid crystal panel 1 that is transparent when the liquid crystal panel 1 is not energized. Thus, so that the light appears to flash on the display surface of the display object 2 with the flashing of the liquid crystal panel 1.

表示物２は、任意の文字、図柄、絵、写真等を表示する部材で、紙材や合成樹脂材、金属材など、任意のシートやフィルムを使用することができる。また、表示面に当たる光によって表示が見えるようにしているので、仕切り２の材質に、透光性のシートやフィルムを使用する必要はない。更に、表示面に当たる光をより効果的に反射せしめる材質、所謂光反射性のシート又はフィルムに印刷された表示面を設けることで、表示面で光が反射して、あたかも、表示面が点滅しているかの如き状態になり、より高い表示効果を得ることができる。 The display object 2 is a member that displays an arbitrary character, pattern, picture, photograph, or the like, and an arbitrary sheet or film such as a paper material, a synthetic resin material, or a metal material can be used. Further, since the display can be seen by the light hitting the display surface, it is not necessary to use a translucent sheet or film as the material of the partition 2. Furthermore, by providing a display surface printed on a so-called light-reflective sheet or film that reflects light that strikes the display surface more effectively , light is reflected on the display surface, as if the display surface blinks. As a result, a higher display effect can be obtained.

図中符号５は収納ケースであり、表示物２と液晶パネル１とを収納する。図示の収納ケース５は、更に制御基盤３と電源４をセットにして収納してある。また、収納ケース５の開口部を透明な被覆材６で閉じ、この被覆材６で液晶パネル１の表面を覆うように設けている。この際、電源４に太陽電池を用いることで、電池交換の必要がない表示装置を提供することができる。図示例では、前記被覆材６を透明なエポキシ樹脂とし、該被覆材６を収納ケース５内に充填して収納ケース５を密閉することで、防水効果や防塵効果に優れた表示装置の提供も可能になる。このような構成の本発明表示装置によると、例えばキーホルダーなどの小物製品に、点滅表示機能を付与することが可能になる。   Reference numeral 5 in the drawing denotes a storage case that stores the display object 2 and the liquid crystal panel 1. The illustrated storage case 5 further stores the control board 3 and the power supply 4 as a set. Further, the opening of the storage case 5 is closed with a transparent covering material 6, and the covering material 6 is provided so as to cover the surface of the liquid crystal panel 1. At this time, by using a solar battery as the power source 4, a display device that does not require battery replacement can be provided. In the illustrated example, the covering material 6 is made of a transparent epoxy resin, the covering material 6 is filled in the storage case 5 and the storage case 5 is sealed, thereby providing a display device having an excellent waterproof effect and dustproof effect. It becomes possible. According to the display device of the present invention having such a configuration, a blinking display function can be given to a small product such as a key holder.

本発明液晶表示装置は、点滅する液晶パネル１を用いて表示物２に注意を惹くように表示するものである。そのため、表示物２の表示面に液晶パネル１を重ねることにある。そして、液晶パネル１通電時に液晶パネル１で表示面を遮蔽し、液晶パネル１無通電時に透明になった液晶パネル１を通して表示面を表示させることで、液晶パネル１の点滅に伴って表示物２の表示面が点滅して見えるように表示される。したがって、従来の表示方法のように、表示物２の裏面から光を通して表示する方法と全く異なる方法となっている。すなわち、もともと見易い表示物２を遮蔽し、視線を遮断することで、点滅表示するといった全く逆の方法を採用している。この結果、周囲が明るいほど効果的な表示効果が得られ、液晶パネルの照度が低いために、昼間に十分な広告効果を得ることはできないといった従来の問題点は解消されたものである。 The liquid crystal display device of the present invention uses a flashing liquid crystal panel 1 to display a display object 2 so as to attract attention. Therefore, the liquid crystal panel 1 is overlaid on the display surface of the display object 2. Then, the display surface is shielded by the liquid crystal panel 1 when the liquid crystal panel 1 is energized, and the display surface is displayed through the liquid crystal panel 1 that is transparent when the liquid crystal panel 1 is not energized. Is displayed so that the display surface appears blinking. Therefore, like the conventional display method, it is a completely different method from the method of displaying light from the back surface of the display object 2. That is, a completely opposite method is employed in which the display object 2 that is easy to see is shielded and the line of sight is blocked to blink. As a result, the brighter the surroundings, the more effective display effect is obtained, and since the illuminance of the liquid crystal panel is low, the conventional problem that a sufficient advertising effect cannot be obtained in the daytime is solved.

尚、本発明における図示例の各構成は、本発明の一実施例に過ぎず、各構成部材の形状、寸法等の設計変更、形態の変更など、現在知られている技術範囲で自由に変更することができるものである。   In addition, each structure of the example of illustration in this invention is only one Example of this invention, and can change freely in the technical range currently known, such as a design change of the shape of each structural member, a dimension, change of a form, etc. Is something that can be done.
