Description

タッチパネルの支持構造およびその製造方法Touch panel support structure and manufacturing method thereof
　本発明は液晶や有機ＥＬ等のディスプレイ素子の上に配置されて、表示素子の表示内容に対応して指やペンを用いた押圧操作で情報を入力するタッチパネルの支持構造およびその製造方法に関する。 The present invention relates to a support structure for a touch panel, which is arranged on a display element such as a liquid crystal or an organic EL, and inputs information by a pressing operation using a finger or a pen corresponding to the display content of the display element, and a manufacturing method thereof.
　多くの電子機器には表示装置として液晶表示素子、有機ＥＬデバイス素子等のフラットパネルディスプレイが用いられる。そして、その表面に電子機器への入力装置としてタッチパネルを重ねて配電して、表示装置の表示に従ってタッチパネルに指などで接触して所望の情報を入力する。
　かかるタッチパネルの支持構造としては、多くは特開２００８−７０７６２号公報に示されるように、前面パネル１０２および固定枠体１０３と液晶ディスプレイ１０５の間にタッチパネル１０４を挟んで支持する構造が採用されている。第１１図に示すように、この構造ではタッチパネル１０４の周囲は前面パネルで押さえられているので、前面パネルが額縁状に出張った形状となり、タッチパネルの周辺は必ず前面パネルと重畳するようにならなければならない。
　また、特開２００５−２４２５０１号公報に示されるように、筐体２０５の窓２５１の周辺に両面テープ２０８でタッチパネルを支持する構造も採用されている。第１２図に示すように、この構造でも同様に筐体２０５自体がタッチパネルの周囲を額縁状に出張った形状となり、タッチパネルの周辺は必ず筐体２０５と重畳するようにならなければならない。 Many electronic devices use flat panel displays such as liquid crystal display elements and organic EL device elements as display devices. Then, a touch panel is superimposed on the surface as an input device to the electronic device and power is distributed, and desired information is input by touching the touch panel with a finger or the like according to the display on the display device.
As a support structure of such a touch panel, a structure in which the touch panel 104 is supported between the front panel 102 and the fixed frame 103 and the liquid crystal display 105 as shown in Japanese Patent Application Laid-Open No. 2008-70762 is adopted. Yes. As shown in FIG. 11, since the periphery of the touch panel 104 is held by the front panel in this structure, the front panel has a shape of a business trip and the periphery of the touch panel must be superimposed on the front panel. I must.
Further, as disclosed in Japanese Patent Laid-Open No. 2005-242501, a structure in which a touch panel is supported by a double-sided tape 208 around the window 251 of the housing 205 is also employed. As shown in FIG. 12, in this structure as well, the case 205 itself has a shape that makes a business trip around the touch panel, and the periphery of the touch panel must always overlap the case 205.
　上述したように、従来のタッチパネルの支持構造では、タッチパネルの周囲は前面パネルあるいは筐体により額縁状になり、タッチパネルの表面が前面パネルあるいは筐体から少し窪んだ状態になるので、タッチパネルに接触する場合に前面パネルあるいは筐体が邪魔になり、特にタッチパネルの周辺部を接触する場合には誤操作にもつながる問題点がある。
　また、従来のタッチパネルの支持構造では、必ず前面パネルあるいは筐体よりなる額縁の出張りが存在するためにデザイン上でも制約を受ける問題点がある。
　更に、従来のタッチパネルの支持構造では、タッチパネルの周囲の前面パネルあるいは筐体の額縁部分の境界に手垢やゴミが付着したりして、使用する期間が長くなれば汚く汚れてしまう問題点もある。
　従って、本発明は上述した従来の問題点に鑑みてなされ、タッチパネルと、前記タッチパネルが収容できる開口部を有する筐体と、筐体の少なくとも前記開口部を覆うように貼られた透明樹脂フィルムとを備え、前記透明樹脂フィルムの裏面に接着材を介して前記タッチパネルを貼り付けることを特徴とする。
　また、本発明は、前記タッチパネルの表面と前記筐体表面を略平面にすることを特徴とする。
　更に、本発明は、前記開口部は前記タッチパネルとほぼ同じ大きさに形成することを特徴とする。
　更に、本発明は、前記タッチパネルは前記接着材を介して前記透明樹脂フィルムで支持されることを特徴とする。
　更に、本発明は、前記接着材を前記タッチパネル表面に全面に設けられることを特徴とする。
　更に、本発明は、前記接着材としてＵＶ硬化性樹脂を用いることを特徴とする。
　更に、本発明は、前記筐体は樹脂製とし、前記透明樹脂フィルムは前記開口部を除く前記筐体に接着されていることを特徴とする。
　更に、本発明の製造方法は、前記筐体の射出成形時に前記透明樹脂フィルムを前記筐体表面にインサート成形することを特徴とする。
　更に、本発明の製造方法は、前記筐体を仰向けにして透明樹脂フィルムの裏側に液状の前記接着材を付着し、その上に前記タッチパネルを前面を前記透明樹脂フィルム側に向けて前記開口部内に置き、前記タッチパネルの自重を利用して前記タッチパネルと前記接着材間にある空気の気泡等を前記開口部と前記タッチパネルの隙間から抜きながら接着することを特徴とする。
　更に、本発明の製造方法は、前記筐体を仰向けのまま前記筐体の前記開口部と前記タッチパネルの隙間に液状の接着用ＵＶ樹脂を滴下して前記筐体と前記タッチパネルの側面とを接着することを特徴とする。
　本発明に依れば、筐体とタッチパネルの表面が平坦化でき、両者の表面を透明樹脂フィルムで覆うことによりシームレス支持構造を実現できる。そして、タッチパネルは全体的に接着材を介して透明樹脂フィルムに固定され、透明樹脂フィルムは筐体に接着されることで強固に固定されるので、従来の額縁などの機械的な支持なしでタッチパネルを筐体に強固に固定できる支持構造を実現できる。
　また、本発明に依れば、従来の額縁状の支持構造を排除することができ、恰も筐体自体がタッチパネルであるようなデザインが可能となる。
　更に、本発明に依れば、透明樹脂フィルムで筐体およびタッチパネル表面をシームレスに覆うので、タッチパネルと筐体の隙間が形成されず、外部からゴミや水分の侵入も防げ、掃除も筐体と同時に行える。
　更に、本発明に依れば、タッチパネルが筐体と一体に取り扱えてカーナビや携帯電話などの電子機器の組み立てがより少ない部品数で行え、組み立て工程の簡素化に役立つ。また、タッチパネルメーカーでタッチパネルを筐体に取り付けてから電子機器メーカーへの供給も可能となる。更に、タッチパネルメーカーでタッチパネルを筐体に組み込んだ後に製品試験を行えるので、タッチパネルの組み立てによる工程不良は電子機器メーカーでは皆無となる。
　また、本発明の製造方法に依れば、筐体の成形においてフィルム　インサート成形を用いることで筐体の射出成形時にその表面を透明樹脂フィルムで覆い接着できるので、シームレス構造を同時に実現できる。
　更に、本発明の製造方法に依れば、筐体を仰向けにして開口部にタッチパネルを固定して作業ができるので、作業性を大幅に向上できる。
　更に、本発明の製造方法に依れば、タッチパネルを筐体に取り付けた後に出荷できるので電子機器メーカーでのタッチパネルの組み立てを不要にできる。 As described above, in the conventional touch panel support structure, the periphery of the touch panel is framed by the front panel or the housing, and the surface of the touch panel is slightly depressed from the front panel or the housing, so that it touches the touch panel.

Further, according to the manufacturing method of the present invention, since the surface can be covered and bonded with a transparent resin film at the time of injection molding of the casing by using film insert molding in the molding of the casing, a seamless structure can be realized at the same time.
Furthermore, according to the manufacturing method of the present invention, the work can be performed with the casing facing up and the touch panel fixed to the opening, so that workability can be greatly improved.
Furthermore, according to the manufacturing method of the present invention, since the touch panel can be shipped after being attached to the casing, it is not necessary to assemble the touch panel at an electronic device manufacturer.

　第１図に本発明のタッチパネルの支持構造を説明する断面図を示す。
　本実施の態様では、タッチパネル１と、タッチパネル１を収容できる開口部２を有する筐体３と、筐体３の表面に接着される透明樹脂フィルム４と、開口部２の透明樹脂フィルム４の裏面に塗布する接着材５とで構成されている。
　タッチパネル１は既に知られているように、液晶ディスプレイよりも少し大きく横長矩形の２枚のガラス板のそれぞれの内面に導電性電極を配置して、表面を指や専用のペン等で触れることで導電性電極を接触させて電気的なボタンとして機能する入力装置である。タッチパネルにはガラスーガラス構造のものやフィルムーガラス構造のものがあり、動作原理としては抵抗膜式、静電容量式あるいは超音波式のものがある。
　筐体３はポリカーボネート樹脂をインサート成形して形成され、上面の中央付近にタッチパネル１と略同じ横長矩形の開口部２が設けられる。開口部２はタッチパネル１が収容できる大きさであり、両者には若干の隙間しか形成されない。筐体３は主として黒色に着色され、中が透視できないようにしている。
　透明樹脂フィルム４は約１００~５００μｍの厚みの高透過性のポリエステル（ＰＥＴ）フィルムで形成され、筐体３の開口部２を完全に覆い、筐体３の他の部分とほぼ重畳して接着されている。この構造により透明樹脂フィルム４は開口部２を除き筐体３の表面で固定され支持されている。透明樹脂フィルム４は表面反射防止フィルムとしても働き、これで覆われる筐体３表面とタッチパネル１表面の反射防止を行う。
　開口部２の透明樹脂フィルム４の裏面には全体にダイレクトボンディング用ＵＶ硬化性樹脂よりなる接着材５が塗布され、タッチパネル１の前面を全体的に透明樹脂フィルム４に貼り付けている。従って、タッチパネル１はこの接着材５で透明樹脂フィルム４に固定され、結果的に透明樹脂フィルム４を介して筐体３で支持される構造になっている。なお、タッチパネル１と筐体３の隙間には接着用ＵＶ樹脂６が充填され、タッチパネル１と筐体３との固着を行い、タッチパネル１は接着材５と接着用ＵＶ樹脂６とで固定支持される。
　液晶ディスプレイ７は筐体３に一端を固定した取り付け金具８を用いてちょうどタッチパネル１のすぐ下側に固定される。なお、液晶ディスプレイ７の代わりに有機ＥＬディスプレイ等の他のフラットパネルディスプレイを用いても良い。
　かかる支持構造に依れば、筐体３とタッチパネル１の表面が平坦化でき、両者の表面を透明樹脂フィルム４で覆うことによりシームレス支持構造を実現できる。これにより従来の額縁状の支持構造をブレークスルーすることができ、恰も筐体３自体がタッチパネルであるようなデザインが可能となる。また、タッチパネル１と筐体３とを透明樹脂フィルム４で被覆するので、外部からゴミや水分の侵入も防げ、掃除も筐体３と同時に行える。
　第２図に本発明のタッチパネルの支持構造を説明する分解斜視図を示す。
　一番上に高透過樹脂フィルム４があり、その下にポリカーボネート樹脂を成形した黒色の筐体３がり、筐体３の開口部２に位置する高透過樹脂フィルム４の裏面に付着されるダイレクトボンディング用ＵＶ硬化性樹脂よりなる接着材５があり、その下にタッチパネル１があり、タッチパネル１と筐体３の隙間に充填される接着用ＵＶ樹脂６がある。
　この支持構造ではタッチパネル１が筐体３と一体に取り扱えてカーナビや携帯電話などの電子機器の組み立てがより少ない部品数で行え、組み立て工程の簡素化に役立つ。また、タッチパネルメーカーでタッチパネル１を筐体３に取り付けてから電子機器メーカーへの供給も可能となる。更に、タッチパネルメーカーでタッチパネル１を筐体３に組み込んだ後に製品試験を行えるので、タッチパネル１の組み立てによる工程不良は皆無となる。
　次に、第３図~第１０図を参照して本発明の製造方法について説明する。
　まず、筐体３の成形工程と、タッチパネル１の透明樹脂フィルム４への貼り付け工程と、タッチパネル１と筐体３の接着工程とで構成されている。
　筐体３の成形工程は第３図~第８図を参照して説明する。
　第３図において、上金型１１と下金型１２とで筐体３の成形形状のキャビティー１３（第７図参照）を形成している。下金型１２には樹脂の射出孔１４が設けられ、ここから加熱されたポリカーボネート樹脂がキャビティー１３に注入される。第３図では下金型１２の表面に透明樹脂フィルム４をフィルム送り装置１５で供給する。なお、上金型１１には既に成形を終えた筐体３が保持されている。
　続いて、第４図に示すように、下金型１２に設けたクランプ１６で透明樹脂フィルム４の端部を押さえ、供給されたフィルムの端部をヒートカットしてフィルム送り装置１５は待機位置に戻る。同時に、取り出しロボット１７が開放された上金型１１と下金型１２の間に侵入してくる。
　続いて、第５図に示すように、成形品をイジェクトタービン１８で上金型１１から引き離し、取り出しロボット１７の上面に設けた吸着チャック１９で筐体３となる成形品を吸着する。同時に、取り出しロボット１７の下面に取り付けたヒーター２０でフィルムを加熱して射出孔１４から減圧してフィルムを下金型１２の面に密着させる。
　続いて、第６図に示すように、取り出しロボット１７が成形品を外部に運び出し、イジェクトタービン１８は上金型１１の中に戻る。同時に、上金型１１を下降させて型閉じを開始する。
　続いて、第７図に示すように、型閉じが完了すると両金型で成形形状のキャビティー１３が形成される。両金型は１３０℃に加熱され、ポリカーボネート樹脂は２２０℃に加熱され１００Ｍｐａの保圧圧力で射出孔１４からキャビティー１３内に射出成形される。この際に筐体３の開口部２に対応する部分は上金型１１がフィルムに密接しているので、ポリカーボネート樹脂は注入されず開口部２が形成される。結果的に、透明樹脂フィルム４は筐体３となる表面と開口部２とを覆い、透明樹脂フィルム４は筐体３の表面に強固に熱圧着されて接着される。このような成形をフィルム　インサート成形と呼んでいる。
　最後に、第８図に示すように、取り出された成形品は外周の不要なはみ出したフィルムをカッター２１でトリミングして透明樹脂フィルム４を接着した筐体３を完成する。
　次に、第９図を参照してタッチパネル１の透明樹脂フィルム４への貼り付け工程について説明する。
　筐体３は仰向けにして透明樹脂フィルム４を下側にして、透明樹脂フィルム４の裏側に液状のダイレクトボンディング用ＵＶ硬化性樹脂よりなる接着材５を付着する。その上にタッチパネル１を前面を透明樹脂フィルム４側に向けて開口部２内に置き、タッチパネル１の自重を利用してタッチパネル１と接着材５間にある空気の気泡等を開口部２とタッチパネル１の隙間から抜く。このときに気泡を良く抜くために減圧してタッチパネル１の接着を行っても良い。タッチパネル１の接着の作業が終了すると、接着材５に紫外線を照射して硬化させる。
　この工程では、開口部２内にタッチパネル１を置くだけで接着が行えるので、タッチパネル１の位置合わせなどが不要となり、作業効率が極めて高くなる。
　更に、第１０図を参照してタッチパネル１と筐体３の接着工程を説明する。
　筐体３は仰向けのまま筐体３の開口部２とタッチパネル１の隙間に液状の接着用ＵＶ樹脂６を滴下する。その後、紫外線を照射して接着用ＵＶ樹脂６の硬化を行う。なお、前述した接着材５と接着用ＵＶ樹脂６の硬化を同時に行っても良い。
　接着用ＵＶ樹脂６はタッチパネル１の側面と筐体３とを強固に接着し、ほとんど同一体であるように強固に支持できる。この結果、タッチパネル１は裏面が浮いていても前面を指などで接触することでスイッチの働きを行える。 FIG. 1 shows a cross-sectional view for explaining a support structure for a touch panel according to the present invention.
In this embodiment, the touch panel 1, a housing 3 having an opening 2 that can accommodate the touch panel 1, a transparent resin film 4 that is bonded to the surface of the housing 3, and the back surface of the transparent resin film 4 in the opening 2. And an adhesive 5 applied to the substrate.
As already known, the touch panel 1 is formed by placing conductive electrodes on the inner surfaces of two horizontally long rectangular glass plates that are slightly larger than the liquid crystal display and touching the surface with a finger or a dedicated pen. This is an input device that functions as an electrical button by contacting a conductive electrode. The touch panel includes a glass-glass structure and a film-glass structure. The operation principle includes a resistance film type, a capacitance type, and an ultrasonic type.
The casing 3 is formed by insert-molding polycarbonate resin, and a horizontally-long rectangular opening 2 that is substantially the same as the touch panel 1 is provided near the center of the upper surface. The opening 2 is sized to accommodate the touch panel 1, and only a slight gap is formed between them. The housing 3 is mainly colored black so that the inside cannot be seen through.
The transparent resin film 4 is formed of a highly permeable polyester (PET) film having a thickness of about 100 to 500 μm, completely covers the opening 2 of the housing 3, and substantially overlaps with the other portions of the housing 3. Has been. With this structure, the transparent resin film 4 is fixed and supported on the surface of the housing 3 except for the opening 2. The transparent resin film 4 also functions as a surface antireflection film, and performs antireflection on the surface of the housing 3 and the surface of the touch panel 1 that are covered with the film.
An adhesive 5 made of a UV curable resin for direct bonding is applied to the entire back surface of the transparent resin film 4 in the opening 2, and the entire front surface of the touch panel 1 is attached to the transparent resin film 4. Therefore, the touch panel 1 is fixed to the transparent resin film 4 with the adhesive material 5, and as a result, is configured to be supported by the housing 3 through the transparent resin film 4. The gap between the touch panel 1 and the housing 3 is filled with an adhesive UV resin 6 to fix the touch panel 1 and the housing 3, and the touch panel 1 is fixedly supported by the adhesive 5 and the adhesive UV resin 6. The
The liquid crystal display 7 is fixed just below the touch panel 1 using a mounting bracket 8 having one end fixed to the housing 3. Instead of the liquid crystal display 7, another flat panel display such as an organic EL display may be used.
According to such a support structure, the surfaces of the housing 3 and the touch panel 1 can be flattened, and a seamless support structure can be realized by covering both surfaces with the transparent resin film 4. As a result, the conventional frame-like support structure can be broken through, and the housing 3 itself can be designed as a touch panel. Moreover, since the touch panel 1 and the housing 3 are covered with the transparent resin film 4, dust and moisture can be prevented from entering from the outside, and cleaning can be performed simultaneously with the housing 3.
FIG. 2 shows an exploded perspective view for explaining the touch panel support structure of the present invention.
There is a high-permeability resin film 4 on the top, a black casing 3 molded with polycarbonate resin underneath, and direct bonding attached to the back surface of the high-permeability resin film 4 located in the opening 2 of the casing 3 There is an adhesive 5 made of a UV curable resin, and there is a touch panel 1 thereunder, and an adhesive UV resin 6 filled in a gap between the touch panel 1 and the housing 3.
In this support structure, the touch panel 1 can be handled integrally with the housing 3 and an electronic device such as a car navigation system or a mobile phone can be assembled with a smaller number of parts, which helps simplify the assembly process. In addition, after the touch panel 1 is attached to the housing 3 by the touch panel manufacturer, the supply to the electronic device manufacturer is also possible. Further, since the product test can be performed after the touch panel 1 is incorporated into the housing 3 by the touch panel manufacturer, there is no process failure due to the assembly of the touch panel 1.
Next, the manufacturing method of the present invention will be described with reference to FIGS.
First, it is comprised by the formation process of the housing | casing 3, the sticking process to the transparent resin film 4 of the touch panel 1, and the adhesion process of the touch panel 1 and the housing | casing 3. FIG.
The molding process of the housing 3 will be described with reference to FIGS.
In FIG. 3, the upper mold 11 and the lower mold 12 form a cavity 13 (see FIG. 7) having a molded shape of the housing 3. The lower mold 12 is provided with a resin injection hole 14 from which a heated polycarbonate resin is injected into the cavity 13. In FIG. 3, the transparent resin film 4 is supplied to the surface of the lower mold 12 by the film feeding device 15. The upper mold 11 holds the housing 3 that has already been molded.
Subsequently, as shown in FIG. 4, the end of the transparent resin film 4 is pressed by the clamp 16 provided in the lower mold 12, and the end of the supplied film is heat-cut, so that the film feeding device 15 is in the standby position. Return to. At the same time, the take-out robot 17 enters between the opened upper mold 11 and lower mold 12.
Subsequently, as shown in FIG. 5, the molded product is pulled away from the upper mold 11 by the eject turbine 18, and the molded product to be the housing 3 is sucked by the suction chuck 19 provided on the upper surface of the take-out robot 17. At the same time, the film is heated by the heater 20 attached to the lower surface of the take-out robot 17 and depressurized from the injection hole 14 so that the film is brought into close contact with the surface of the lower mold 12.
Subsequently, as shown in FIG. 6, the take-out robot 17 carries the molded product to the outside, and the eject turbine 18 returns to the upper mold 11. At the same time, the upper mold 11 is lowered to start mold closing.
Subsequently, as shown in FIG. 7, when the mold closing is completed, a mold-shaped cavity 13 is formed by both molds. Both molds are heated to 130 ° C., and the polycarbonate resin is heated to 220 ° C. and injection molded from the injection hole 14 into the cavity 13 with a holding pressure of 100 Mpa. At this time, since the upper mold 11 is in close contact with the film at the portion corresponding to the opening 2 of the housing 3, the opening 2 is formed without pouring polycarbonate resin. As a result, the transparent resin film 4 covers the surface to be the housing 3 and the opening 2, and the transparent resin film 4 is firmly thermocompression bonded to the surface of the housing 3. Such molding is called film insert molding.
Finally, as shown in FIG. 8, a film 3 that has been taken out of the outer periphery of the molded product that has been taken out is trimmed with a cutter 21 to complete the housing 3 to which the transparent resin film 4 is adhered.
Next, the process of attaching the touch panel 1 to the transparent resin film 4 will be described with reference to FIG.
The housing 3 is turned upside down and the transparent resin film 4 is on the lower side, and an adhesive 5 made of a liquid UV curable resin for direct bonding is attached to the back side of the transparent resin film 4. On top of that, the touch panel 1 is placed in the opening 2 with the front surface facing the transparent resin film 4, and air bubbles or the like between the touch panel 1 and the adhesive 5 are removed from the opening 2 and the touch panel using the weight of the touch panel 1. Pull out from the gap of 1. At this time, the touch panel 1 may be bonded under reduced pressure in order to remove bubbles well. When the operation of bonding the touch panel 1 is completed, the adhesive material 5 is irradiated with ultraviolet rays and cured.
In this step, since the bonding can be performed simply by placing the touch panel 1 in the opening 2, the alignment of the touch panel 1 is not necessary, and the working efficiency becomes extremely high.
Furthermore, the adhesion process of the touch panel 1 and the housing | casing 3 is demonstrated with reference to FIG.
The liquid bonding UV resin 6 is dropped into the gap between the opening 2 of the housing 3 and the touch panel 1 with the housing 3 facing up. Thereafter, the adhesive UV resin 6 is cured by irradiating with ultraviolet rays. The adhesive 5 and the adhesive UV resin 6 described above may be cured simultaneously.
The bonding UV resin 6 firmly bonds the side surface of the touch panel 1 and the housing 3 and can be firmly supported so as to be almost the same body. As a result, the touch panel 1 can function as a switch by touching the front surface with a finger or the like even when the back surface is floating.
