Description

【０００１】
【発明の属する技術分野】
この発明は、フィルム液晶装置を表示部材として用い、そのフィルム液晶装置を湾曲状態でケースに組み付けた場合でも視認性の低下を防止できる携帯電子機器に関する。
【０００２】
【従来の技術】
最近はフィルム液晶装置を湾曲してケース内に設置して、表示面を湾曲した状態で保持する構成の腕時計、その他の携帯電子機器が普及を始めている。このようなフィルム液晶装置を湾曲してケース内に支持する手法としては、例えば特開平６−６６９６９号公報に記載の腕時計の構造が知られている。係る腕時計の構造では、時計ケースの上部からフィルム液晶装置を組み込む構造となっており、前記時計ケースに湾曲した支持面を有する凹部が形成されており、この凹部の湾曲支持面に沿ってフィルム液晶装置を湾曲させ、この湾曲状態を維持して固定される。
【０００３】
また、ケースの凹部の内周面には段部が形成されており、この段部の高さはフィルム液晶装置よりも若干高くなるように形成されており、この段部に対してガラス面等の表示用透明部材をフィルム液晶装置の上から組み込み、フィルム液晶装置を表示用透明部材とケースの支持面とで挟み込み固定する。これにより、前記フィルム液晶装置と表示用透明部材とが一定の間隙を保って表示用透明部材が固定され、腕時計の薄型化を実現する。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の腕時計の構造では、フィルム液晶装置と表示用透明部材とが一定の間隙をもって固定されているため、表示が奥目（「奥目」は定義するのが好ましいと思います）になってしまい、表示内容の視認性が低下するという問題点があった。なお、「奥目」とは、ケースに設けられたガラス等を通して表示される数字や文字を見たときに、それらの数字等がそのガラスに対して奥に配置してあると認識できる程度をいう。
【０００５】
そこで、この発明は、上記に鑑みてなされたものであって、湾曲してケースに組み付けた状態でフィルム液晶装置の表示内容の視認性を向上できる携帯電子機器を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記のような観点から、この発明の携帯電子機器は、複数の固定穴を有するフィルム液晶装置と、前記固定穴に対応する位置に案内突起を有し、少なくとも内面が湾曲した形状の表示用透明部材とを備え、フィルム液晶装置の固定穴に案内突起を通し前記案内突起を固定穴に対して固定し、この状態でケース内に収容するものである。
【０００７】
フィルム液晶装置を表示用透明部材の湾曲に沿って固定するにあたり、表示用透明部材に設けた案内突起をフィルム液晶装置の固定穴に通して固定することで、フィルム液晶装置が湾曲状態で且つ表示用透明部材に対して極小の隙間をもって固定される。また、好ましい態様では、フィルム液晶装置がギャップ変化を起こすことなく、表示用透明部材の内側面に当接して固定される。これにより、フィルム液晶装置の表示内容が奥目になるのを抑制できるから、高い視認性を保つことができる。なお、案内突起と固定穴との固定方法は、かしめやしまりばめ等の公知のものを適宜選択して用いることができる。
【０００８】
また、この発明において、前記案内突起と固定穴とは、それぞれフィルム液晶装置が湾曲した状態での山頂部と裾野部とに位置しているのが好ましい。すなわち、フィルム液晶装置が比較的硬いため湾曲し難いため、湾曲した状態の山頂部で固定すると共に更に両方の裾野部で固定を行うことで、安定した湾曲形状を維持でき、ギャップ変化を抑制できる。
【０００９】
また、この発明の携帯電子機器では、更に、前記フィルム液晶装置の背面に配置されるバックライトを有し、このバックライトに前記案内突起に対応した固定穴が設けられ、前記案内突起をフィルム液晶装置の固定穴を貫通させ、少なくともバックライトの固定穴をもって固定する。
【００１０】
このように、案内突起によりフィルム液晶装置と共にＥＬ等のバックライトを固定できれば、表示用透明部材にフィルム液晶装置とバックライトとを一体に組み込んでケース内に収容できる。
【００１１】
また、この発明の携帯電子機器では、更に、前記フィルム液晶装置の背面に配置されるバックライトを有し、このバックライトに前記案内突起に対応した固定穴が設けられ、前記案内突起をフィルム液晶装置の固定穴およびバックライトの固定穴を貫通させ、バックライトの側面を押える押え板を配置し、この押え板の固定穴に前記貫通した案内突起を固定する。バックライトの押え板によりバックライトおよびフィルム液晶装置を押えることで、これらの固定が安定するので、より視認性が向上する。
【００１２】
また、この発明の携帯電子機器は、フィルム液晶装置と、少なくとも内面が湾曲した形状であり、フィルム液晶装置の側面を嵌め入れる溝を有し且つこの溝が前記内面に近接状態になるレール体を設けた表示用透明部材とを備え、このレール体の溝にフィルム液晶装置の側面を嵌め入れて固定し、この状態でケース内に収容するものである。
【００１３】
フィルム液晶装置をレール体の溝に嵌め入れて固定すると、前記溝が表示用透明部材の内面に近接状態になっているため、フィルム液晶装置と表示用透明部材の湾曲内面とが極小の間隙をもって固定される。これにより、フィルム液晶装置の表示内容が奥目になるのを抑制できるから、高い視認性を保つことができる。なお、レール体は表示用透明部材と一体成形でもよいし後付けであってもよい。
【００１４】
また、この発明において、前記レール体に対し、バックライトの側面を嵌め入れる溝を、前記フィルム液晶装置を嵌め入れる溝の下方に近接して形成するのが好ましい。
【００１５】
ＥＬ等の湾曲可能なバックライトの側面を嵌め入れる溝をレール体に設けることで、表示用透明部材にフィルム液晶装置とバックライトとを一体に組み込んでケース内に収容できる。
【００１６】
【発明の実施の形態】
以下、この発明につき図面を参照しつつ詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。また、下記実施の形態の各要素には、置換容易であるか或いは実質的に同一の要素が含まれることはいうまでもない。
【００１７】
実施の形態１
図１は、この発明の実施の形態１に係る腕時計を示す組立図である。この腕時計１００は、表示用透明部材１と、フィルム液晶装置２と、ＥＬパネル３と、回路ブロック４と、機器ケース５とから主に構成されている。表示用透明部材１は、ガラスや透明樹脂等から構成される。また、表示用透明部材１は、フィルム液晶装置２のアクティブエリアに対応する部分が透明の表示領域となり、その周囲がフィルム液晶装置２の受台１１となる。受台１１には、複数の案内ピン１２が一体形成され、表示用透明部材１の内側湾曲面の山頂部１３に対応する位置に一対設けられ、その山頂部１３の両側の裾野部分１４にそれぞれ一対設けられている。案内ピン１２は段部を有し、大径部分１２ａをフィルム液晶装置２の固定用に、小径部分１２ｂをＥＬパネル３の固定用に使用する。
【００１８】
なお、案内ピン１２は表示用透明部材１と一体成形しなくても、後付け可能である。一方、フィルム液晶装置２のアクティブエリアの周囲には、複数のカシメ穴２１が設けられている。このカシメ穴２１は、上記案内ピン１２にそれぞれ対応する位置に穿孔され、その穴径は案内ピン１２の大径部分１２ａが遊嵌できる程度とするのが好ましい。更に、フィルム液晶装置２の背面にはＥＬパネル３が配置され、前記ＥＬパネル３の周囲にも前記案内ピン１２に対応したカシメ穴３１が複数形成されている。なお、バックライトは、ＥＬパネル３に限定されず、湾曲成形した導光板とＬＥＤ等の光源とから構成したものであってもよい（図示省略）。この場合は、導光板の周囲にカシメ穴を穿孔すればよい。
【００１９】
次に、この腕時計１００の組み立て工程を説明する。先ず、表示用透明部材１の案内ピン１２の大径部分１２ａがフィルム液晶装置２のカシメ穴２１を貫通するようにし、フィルム液晶装置２を湾曲させながら、表示用透明部材１とフィルム液晶装置２との位置合わせを行いつつ取り付ける。続いて、ＥＬパネル３のカシメ穴３１に前記案内ピン１２の小径部分１２ｂが貫通するようにＥＬパネル３の位置合わせを行い、このＥＬパネル３のカシメ穴３１を通った案内ピン１２の先端を熱カシメする。これにより、ＥＬパネル３とフィルム液晶装置２が表示用透明部材１に対して固定される。固定した状態を図２の斜視図に示す。
【００２０】
また、フィルム液晶装置２を湾曲させた状態で湾曲頂部２２が表示用透明部材１の内面の山形頂部１３にて固定され、その両側の裾野部２３において更に固定されている。このように、フィルム液晶装置２の湾曲頂部２２および裾野部２３で固定することで、組立時にフィルム液晶装置２に無理な力が加わるのが防止され、ギャップムラの発生が防止される。フィルム液晶装置２およびＥＬパネル３を表示用透明部材１に固定した状態で、表示用透明部材１とフィルム液晶装置２との間隙は表示用透明部材１の受台１１の高さで規制され、両者の間隙が極小に保たれる。この結果、フィルム液晶装置２の表示内容が奥目になることなく、その視認性を向上できる。また、フィルム液晶装置２の製造精度にばらつきが生じた場合は、従来の構造では表示用透明部材１との間隙が不均一になっていたが、案内ピン１２により固定することでフィルム液晶装置２の厚みにばらつきが生じていても、狙った曲率に湾曲させやすく、より視認性が高まる。
【００２１】
なお、フィルム液晶装置２とＥＬパネル３との間隙は、案内ピン１２の大径部分１２ａの高さにより規制され、前記高さがフィルム液晶装置２の厚さより小さければフィルム液晶装置２とＥＬパネル３とは密着状態で固定され、前記高さがフィルム液晶装置２の厚さより大きければその差分の間隙をもってフィルム液晶装置２とＥＬパネル３とが固定される。フィルム液晶装置２およびＥＬパネル３を固定した後は、回路ブロック４と共に時計ケース５内に収納する。
【００２２】
なお、図示しないが、カシメ穴２１と案内ピン１２をしまりばめの状態にして熱カシメすることなく、案内ピン１２を圧入するようにしてもよい。更に案内ピン１２に代えて矩形の板状突起等の、カシメ穴２１を貫通させてカシメ或いは圧入が可能な構造であれば、同図に示したものに限定されない。また、受台１１の高さは極小であるのが好ましく、更にはフィルム液晶装置２を湾曲させると若干鞍状に変形して中央部分が低くなるので、受台１１は実質的には高さを有しなくてもよい。
【００２３】
図３は、上記腕時計の変形例を示す組立図である。同図に示すように、矩形の湾曲した押え板６をＥＬパネル３の背面側部に配置し、前記押え板６に設けたカシメ穴６１に案内ピン１２を貫通させ、この状態で熱カシメを行うようにしてもよい。このようにすれば、押え板６と受台１１とによりフィルム液晶装置２およびＥＬパネル３が側部で挟み込まれて固定される。図４にその固定状態の斜視図を示す。これにより、安定した固定が行えると共にフィルム液晶装置２の湾曲精度を向上できるので、表示用透明部材１の曲率と合致させやすくなる結果、表示内容の視認性を更に向上できる。
【００２４】
実施の形態２
図５は、この発明の実施の形態２に係る腕時計を示す組立図である。この腕時計２００は、上記同様、表示用透明部材２０１と、フィルム液晶装置２０２と、ＥＬパネル２０３と、回路ブロック４と、機器ケース５とから主に構成されている。表示用透明部材２０１の背面には、フィルム液晶装置２０２の側部２２１を嵌め込む溝２１１を有するレール体２１２が形成されている。また、レール体２１２にはフィルム液晶装置２０２１用の溝２１１に沿って、ＥＬパネル２０３の側部２３１を嵌め込む溝２１３が形成されている。
【００２５】
フィルム液晶装置２０２は、溝２１１の形成方向端部（図示省略）から所定位置まで差し込まれて固定される。フィルム液晶装置２０２を固定した状態を図６の斜視図に示す。続いて、ＥＬパネル２０３を、同様に溝２１３の形成方向端部（図示省略）から所定位置まで差し込み固定する。ＥＬパネル２０３を固定した状態を図７の斜視図に示す。フィルム液晶装置２０２用の溝２１１は、表示用透明部材２０１の湾曲面２１４に近接して形成されており、この溝２１１にフィルム液晶装置２０２を嵌め込むことでフィルム液晶装置２０２と表示用透明部材２０１との間隙を極小に保ことができる。これにより、フィルム液晶装置２０２の表示内容の視認性を向上できる。
【００２６】
また、レール体２１２を形成することで組立作業を簡単にできる。なお、前記レール体２１２は表示用透明部材２０１と一体で成形してもよいし、後付けしてもよい。更に、レール体２１２の溝２１１、２１３に代えて複数の突起物を側方に形成し、この突起物により実質的な溝を形成してフィルム液晶装置２０２を固定するようにしてもよい（図示省略）。
【００２７】
以上の実施の形態１および２において、フィルム液晶装置２、２０２が波状に湾曲する場合も同様の構成で固定できる。また、表示用透明部材１、２０１は、内面がフィルム液晶装置２、２０２と同じように湾曲していればよく、必ずしも外面が同様の形状で湾曲していなくてもよい。また、ＥＬパネル３、２０３に代えて、導光板を固定して前記導光板の端部にＬＥＤを設置するように構成してもよい。この場合、導光板にＥＬパネルと同様のカシメ穴を設け、前記案内ピンにより固定する。
【００２８】
また、上記実施の形態では、腕時計を例示して説明したが、これに限定されず、例えば携帯電話、小型液晶ＴＶ等の各種携帯電子機器にも適用できる。
【００２９】
【発明の効果】
以上説明したように、この発明の携帯電子機器では、複数の固定穴を有するフィルム液晶装置と、前記固定穴に対応する位置に案内突起を有し、少なくとも内面が湾曲した形状の表示用透明部材とを備え、フィルム液晶装置の固定穴に案内突起を通し前記案内突起を固定穴に対して固定し、この状態でケース内に収容するようにしたので、フィルム液晶装置の表示内容の視認性を向上できる。
【００３０】
また、この発明の携帯電子機器では、案内突起と固定穴とを、それぞれフィルム液晶装置が湾曲した状態での山頂部と裾野部とに位置させることで、フィルム液晶装置を安定した湾曲させることができる。
【００３１】
また、この発明の携帯電子機器では、フィルム液晶装置の背面に配置されるバックライトを有し、このバックライトに前記案内突起に対応した固定穴が設けられ、前記案内突起をフィルム液晶装置の固定穴を貫通させ、少なくともバックライトの固定穴をもって固定するので、携帯電子機器の組立性を向上できる。
【００３２】
また、この発明の携帯電子機器では、フィルム液晶装置の背面に配置されるバックライトを有し、このバックライトに前記案内突起に対応した固定穴が設けられ、前記案内突起をフィルム液晶装置の固定穴およびバックライトの固定穴を貫通させ、バックライトの側面を押える押え板を配置し、この押え板の固定穴に前記貫通した案内突起を固定するので、携帯電子機器の組立性を向上でき且つ視認性を向上できる。
【００３３】
また、この発明の携帯電子機器では、フィルム液晶装置と、少なくとも内面が湾曲した形状であり、フィルム液晶装置の側面を嵌め入れる溝を有し且つこの溝が前記内面に近接状態になるレール体を設けた表示用透明部材とを備え、このレール体の溝にフィルム液晶装置の側面を嵌め入れて固定し、この状態でケース内に収容するので、フィルム液晶装置の表示内容の視認性を向上できる。
【００３４】
また、この発明の形態電子機器では、レール体が、バックライトの側面を嵌め入れる溝を、前記フィルム液晶装置を嵌め入れる溝の下方に近接して有するので、携帯電子機器の組立性を向上できる。

BACKGROUND OF THE INVENTION
The present invention relates to a portable electronic device that can prevent a decrease in visibility even when a film liquid crystal device is used as a display member and the film liquid crystal device is assembled in a case in a curved state.
[0002]
[Prior art]
Recently, wristwatches and other portable electronic devices having a configuration in which a film liquid crystal device is curved and installed in a case and the display surface is held in a curved state have begun to spread. As a method for bending and supporting such a film liquid crystal device in a case, for example, the structure of a wristwatch described in JP-A-6-66969 is known. In such a wristwatch structure, a film liquid crystal device is incorporated from above the watch case, and a concave portion having a curved support surface is formed in the watch case, and a film liquid crystal is formed along the curved support surface of the concave portion. The device is bent and fixed while maintaining this bent state.
[0003]
Further, a step portion is formed on the inner peripheral surface of the concave portion of the case, and the height of the step portion is formed so as to be slightly higher than the film liquid crystal device. The display transparent member is assembled from above the film liquid crystal device, and the film liquid crystal device is sandwiched and fixed between the display transparent member and the support surface of the case. As a result, the transparent display member is fixed with the film liquid crystal device and the transparent display member kept at a certain gap, and the watch is made thinner.
[0004]
[Problems to be solved by the invention]
However, in the structure of the above conventional wristwatch, the film liquid crystal device and the transparent display member are fixed with a certain gap, so that the display is on the back (I prefer to define “back”). As a result, there is a problem that the visibility of the display content is lowered. “Okume” refers to the degree to which numbers and characters displayed through the glass etc. provided on the case can be recognized as being located behind the glass. Say.
[0005]
Therefore, the present invention has been made in view of the above, and an object of the present invention is to provide a portable electronic device that can improve the visibility of display contents of a film liquid crystal device in a state of being bent and assembled to a case.
[0006]
[Means for Solving the Problems]
In view of the above, the portable electronic device of the present invention includes a film liquid crystal device having a plurality of fixing holes, a transparent display for display having a guide protrusion at a position corresponding to the fixing holes, and at least an inner surface being curved. The guide projection is passed through the fixing hole of the film liquid crystal device, the guide projection is fixed to the fixing hole, and is accommodated in the case in this state.
[0007]
When the film liquid crystal device is fixed along the curve of the display transparent member, the guide projection provided on the display transparent member is fixed through the fixing hole of the film liquid crystal device, so that the film liquid crystal device is in a curved state and displayed. It is fixed to the transparent member with a minimal gap. In a preferred embodiment, the film liquid crystal device is fixed in contact with the inner surface of the display transparent member without causing a gap change. Thereby, since it can suppress that the display content of a film liquid crystal device becomes a backdrop, high visibility can be maintained. As a method for fixing the guide projection and the fixing hole, a known method such as caulking or interference fitting can be appropriately selected and used.
[0008]
In the present invention, it is preferable that the guide protrusion and the fixing hole are respectively positioned at a peak portion and a skirt portion when the film liquid crystal device is curved. In other words, since the film liquid crystal device is relatively hard and difficult to bend, it is possible to maintain a stable curved shape and to suppress a gap change by fixing at the top of the curved state and further fixing at both skirts. .
[0009]
The portable electronic device according to the present invention further includes a backlight disposed on a back surface of the film liquid crystal device, and the backlight is provided with a fixing hole corresponding to the guide protrusion, and the guide protrusion is provided with the film liquid crystal. The fixing hole of the device is penetrated, and at least the fixing hole of the backlight is fixed.
[0010]
Thus, if a backlight such as an EL can be fixed together with the film liquid crystal device by the guide projection, the film liquid crystal device and the backlight can be integrated into the display transparent member and accommodated in the case.
[0011]
The portable electronic device according to the present invention further includes a backlight disposed on a back surface of the film liquid crystal device, and the backlight is provided with a fixing hole corresponding to the guide protrusion, and the guide protrusion is provided with the film liquid crystal. A fixing plate for pressing the side surface of the backlight is disposed through the fixing hole of the device and the fixing hole of the backlight, and the penetrating guide protrusion is fixed to the fixing hole of the pressing plate. By pressing the backlight and the film liquid crystal device with the backlight pressing plate, the fixation of these is stabilized, so that the visibility is further improved.
[0012]
According to another aspect of the present invention, there is provided a portable electronic device comprising: a film liquid crystal device; and a rail body having at least a curved inner surface and having a groove into which the side surface of the film liquid crystal device is fitted and the groove being in proximity to the inner surface. A transparent member for display provided, and the side surface of the film liquid crystal device is fitted and fixed in the groove of the rail body, and is accommodated in the case in this state.
[0013]
When the film liquid crystal device is fitted and fixed in the groove of the rail body, the groove is in a state of being close to the inner surface of the display transparent member, so that the film liquid crystal device and the curved inner surface of the display transparent member have a minimal gap. Fixed. Thereby, since it can suppress that the display content of a film liquid crystal device becomes a backdrop, high visibility can be maintained. The rail body may be integrally formed with the display transparent member or may be retrofitted.
[0014]
In the present invention, it is preferable that a groove into which the side surface of the backlight is fitted is formed in the rail body in the vicinity of the groove into which the film liquid crystal device is fitted.
[0015]
By providing the rail body with a groove into which the side surface of the bendable backlight such as EL is fitted, the film liquid crystal device and the backlight can be integrated into the display transparent member and accommodated in the case.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. Further, it goes without saying that each element in the following embodiment can be easily replaced or includes substantially the same element.
[0017]
Embodiment 1
1 is an assembly view showing a wristwatch according to Embodiment 1 of the present invention. The wristwatch 100 mainly includes a display transparent member 1, a film liquid crystal device 2, an EL panel 3, a circuit block 4, and a device case 5. The display transparent member 1 is made of glass, transparent resin, or the like. In addition, the display transparent member 1 is a transparent display region in a portion corresponding to the active area of the film liquid crystal device 2, and the periphery thereof is a cradle 11 of the film liquid crystal device 2. A plurality of guide pins 12 are integrally formed on the cradle 11 and are provided in pairs at positions corresponding to the peak portions 13 of the inner curved surface of the display transparent member 1, and are respectively provided on the skirt portions 14 on both sides of the peak portions 13. A pair is provided. The guide pin 12 has a stepped portion, and the large diameter portion 12 a is used for fixing the film liquid crystal device 2 and the small diameter portion 12 b is used for fixing the EL panel 3.
[0018]
The guide pin 12 can be retrofitted without being integrally formed with the display transparent member 1. On the other hand, a plurality of crimping holes 21 are provided around the active area of the film liquid crystal device 2. The caulking hole 21 is preferably drilled at a position corresponding to each of the guide pins 12, and the hole diameter is preferably set such that the large diameter portion 12a of the guide pin 12 can be loosely fitted. Further, an EL panel 3 is disposed on the back surface of the film liquid crystal device 2, and a plurality of crimping holes 31 corresponding to the guide pins 12 are formed around the EL panel 3. Note that the backlight is not limited to the EL panel 3, and may be a curved light guide plate and a light source such as an LED (not shown). In this case, a caulking hole may be drilled around the light guide plate.
[0019]
Next, the assembly process of the wristwatch 100 will be described. First, the transparent member for display 1 and the film liquid crystal device 2 are bent while the film liquid crystal device 2 is curved such that the large diameter portion 12 a of the guide pin 12 of the transparent display member 1 penetrates the caulking hole 21 of the film liquid crystal device 2. Install while aligning with. Subsequently, the EL panel 3 is aligned so that the small diameter portion 12b of the guide pin 12 passes through the caulking hole 31 of the EL panel 3, and the tip of the guide pin 12 passing through the caulking hole 31 of the EL panel 3 is positioned. Caulking with heat. Thereby, the EL panel 3 and the film liquid crystal device 2 are fixed to the transparent member 1 for display. The fixed state is shown in the perspective view of FIG.
[0020]
Further, in a state where the film liquid crystal device 2 is curved, the curved top portion 22 is fixed at the mountain-shaped top portion 13 on the inner surface of the display transparent member 1 and further fixed at the skirt portions 23 on both sides thereof. In this way, by fixing at the curved top portion 22 and the skirt portion 23 of the film liquid crystal device 2, an excessive force is prevented from being applied to the film liquid crystal device 2 at the time of assembly, and the occurrence of gap unevenness is prevented. With the film liquid crystal device 2 and the EL panel 3 fixed to the display transparent member 1, the gap between the display transparent member 1 and the film liquid crystal device 2 is regulated by the height of the cradle 11 of the display transparent member 1, The gap between the two is kept to a minimum. As a result, the visibility of the film liquid crystal device 2 can be improved without making the display content in the back. When the manufacturing accuracy of the film liquid crystal device 2 varies, the gap with the transparent display member 1 is not uniform in the conventional structure. However, the film liquid crystal device 2 is fixed by the guide pins 12. Even if there is variation in the thickness of the film, it is easy to bend to the targeted curvature, and the visibility is further improved.
[0021]
