Description

本発明は、タッチパネル装置に関するものである。   The present invention relates to a touch panel device.

従来、湾曲可能なタッチパネルは、上面の透明電極を有する基板と下面の透明電極を有するフィルムとが空間を介在させて対向し、空間に配置されたドットスペーサにより湾曲させたり捩じったりしてもショートが発生しないタッチパネル（下記特許文献１参照）や、上部フィルム基板および下部フィルム基板を透明プラスチックフィルムで構成したタッチパネル（下記特許文献２参照）や、曲面状のタッチ面を有した静電容量方式タッチパネルの背面に画像を投射する表示装置（下記特許文献３参照）や、球面状の表示画面の前面に取付けて用いられる平面状の検出面を有するタッチスクリーン（下記特許文献４参照）があった。   Conventionally, a bendable touch panel has a substrate having a transparent electrode on the upper surface and a film having a transparent electrode on the lower surface facing each other through a space, and is bent or twisted by a dot spacer disposed in the space. Touch panel (see Patent Document 1 below), a touch panel in which the upper film substrate and the lower film substrate are made of a transparent plastic film (see Patent Document 2 below), and a capacitance having a curved touch surface There is a display device that projects an image on the back of a touch panel (see Patent Document 3 below) and a touch screen (see Patent Document 4 below) that has a flat detection surface that is attached to the front surface of a spherical display screen. It was.

また、下記特許文献５乃至７では、入力装置の直線性不良を防止するために、電極を傾斜、Ｖ字、湾曲させて配置していた。   Further, in Patent Documents 5 to 7 below, in order to prevent poor linearity of the input device, the electrodes are arranged in an inclined, V-shaped, or curved shape.

特開２００８−１０２９６８号JP 2008-102968 A 特開２００８−０４７０２６号JP 2008-047026 A 特開２００７−２７９８１９号JP 2007-279819 A 特開昭６３−６６６２８号JP-A-63-66628 特開平６−２６６４９１号JP-A-6-266491 特開昭５６−５００２３０号JP 56-500230 A 特開昭４７−３６９２３号JP 47-36923 A

しかしながら、上記した従来のタッチパネル装置では、上記特許文献１および２は、タッチパネルを湾曲させて使用することはできるが、表示を正面から見たときの表示とタッチ位置との位置ずれを補正することができず、上記特許文献３は、投射画像とタッチ位置の位置ずれは低減できるが、平面状の液晶パネルと投射画像の歪みが生じる恐れがある。上記特許文献４は、視差補正方法により位置ずれは補正されるが、タッチスクリーン自体を湾曲させて使用することができないといった問題があった。また、上記特許文献５乃至７においても、タッチパネル自体を湾曲させて使用することができないといった問題があった。   However, in the above-described conventional touch panel device, Patent Documents 1 and 2 can be used by curving the touch panel, but correct the positional deviation between the display and the touch position when the display is viewed from the front. In Japanese Patent Application Laid-Open No. 2004-260688, the positional deviation between the projected image and the touch position can be reduced, but there is a risk that the flat liquid crystal panel and the projected image are distorted. Although the above-mentioned Patent Document 4 corrects the positional deviation by the parallax correction method, there is a problem that the touch screen itself cannot be curved and used. In addition, the above Patent Documents 5 to 7 also have a problem that the touch panel itself cannot be bent and used.

そこで本発明は、上記状況に鑑みて、複雑な回路や演算を必要とせずに湾曲させて使用したときの位置精度を向上させることができるタッチパネル装置を提供することを目的とする。   SUMMARY OF THE INVENTION In view of the above situation, an object of the present invention is to provide a touch panel device that can improve the positional accuracy when it is curved and used without requiring a complicated circuit or calculation.

以下、本発明の実施例について、図面を参照しながら詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 4 is a perspective view of a touch panel device representing a first embodiment of the present invention, and FIG. 4 is a principle diagram of positional deviation when a conventional touch panel device is bent and used.

これらの図において、１は可動側透明基板、２は可動側透明基板１の電極、３は電極２に接続される引き回しパターン、４は粘着糊、５は絶縁レジスト、６はドットスペーサ、７は固定側透明基板、８は固定側透明基板７の電極、９は電極８に接続される引き回しパターン、１０はコントロール基板、１１はコネクタ、１２はフレキシブルプリント基板である。可動側透明基板１には、対向する１対の辺が内側に湾曲するＩＴＯ膜からなる能動領域１ａ、能動領域１ａの湾曲していない対向する端部にＡｇペーストからなる電極２が形成され、能動領域１ａの周囲に電極２に接続されるＡｇペーストからなる引き回しパターン３が形成され、能動領域１ａの周囲に粘着糊４が配設されている。固定側透明基板７には、矩形状のＩＴＯ膜からなる能動領域７ａと、電極２と直交する方向の能動領域７ａの対向する端部にＡｇペーストからなる電極８が形成され、能動領域７ａの周囲に電極８に接続されるＡｇペーストからなる引き回しパターン９が形成され、能動領域７ａ上にドットスペーサ６が配設されるとともに能動領域７ａの周囲に絶縁レジスト５が配設されている。   In these drawings, 1 is a movable transparent substrate, 2 is an electrode of the movable transparent substrate 1, 3 is a drawing pattern connected to the electrode 2, 4 is adhesive glue, 5 is an insulating resist, 6 is a dot spacer, 7 is A fixed transparent substrate, 8 is an electrode of the fixed transparent substrate 7, 9 is a routing pattern connected to the electrode 8, 10 is a control substrate, 11 is a connector, and 12 is a flexible printed circuit board. The movable transparent substrate 1 is formed with an active region 1a made of an ITO film having a pair of opposing sides curved inward, and an electrode 2 made of Ag paste at the opposite end of the active region 1a that is not curved, A lead pattern 3 made of Ag paste connected to the electrode 2 is formed around the active region 1a, and an adhesive paste 4 is arranged around the active region 1a. The fixed transparent substrate 7 is formed with an active region 7a made of a rectangular ITO film and an electrode 8 made of an Ag paste at opposite ends of the active region 7a in the direction orthogonal to the electrode 2, and the active region 7a A lead pattern 9 made of Ag paste connected to the electrode 8 is formed in the periphery, a dot spacer 6 is disposed on the active region 7a, and an insulating resist 5 is disposed around the active region 7a.

可動側透明基板１がドットスペーサ６により一定の間隔をあけて固定側透明基板７上に配置され、粘着糊４によって固定される。このとき、引き回しパターン３および９が導電性接着剤（図示なし）でフレキシブルプリント基板１２に接続される。そして、コントロール基板１０に実装されたコネクタ１１にフレキシブルプリント基板１２を接続することで、タッチパネル装置１３が完成される。   The movable-side transparent substrate 1 is arranged on the fixed-side transparent substrate 7 at a predetermined interval by dot spacers 6 and fixed by the adhesive paste 4. At this time, the routing patterns 3 and 9 are connected to the flexible printed circuit board 12 with a conductive adhesive (not shown). The touch panel device 13 is completed by connecting the flexible printed board 12 to the connector 11 mounted on the control board 10.

以上のように構成された本発明のタッチパネル装置は、図１のＸ方向に湾曲が可能であって、可動側透明基板１の能動領域１ａを押下すると、固定側透明基板７の能動領域７ａと接触し、測定された電圧値により押下した座標位置が決定される。可動側透明基板１の能動領域１ａを対向する１対の辺が内側へ湾曲するＩＴＯ膜で形成することで、湾曲させて使用しても表示装置１４の表示に合わせて押下した点とタッチパネル装置１３で検出される点の位置ずれを補正することができるため、位置ずれが抑制できる。   The touch panel device of the present invention configured as described above can be bent in the X direction of FIG. 1, and when the active region 1 a of the movable transparent substrate 1 is pressed, the active region 7 a of the fixed transparent substrate 7 The pressed coordinate position is determined by the touched voltage value measured. A touch panel device in which the active region 1a of the movable-side transparent substrate 1 is formed of an ITO film having a pair of opposing sides curved inward, so that it is pressed in accordance with the display of the display device 14 even if it is curved. Since the position shift of the point detected at 13 can be corrected, the position shift can be suppressed.

ここで、従来のタッチパネル装置を湾曲させた場合に生じる位置ずれの原理と本発明のタッチパネル装置の補正方法について説明する。図４に示すように、従来のタッチパネル装置１００を湾曲した表示装置１４に距離ｔの間隔をあけて装着した場合、表示装置１４のα点に表示されたボタンを見ながらタッチパネル装置１００のβ点を押下すると、実際には表示装置１４のγ点を押下したことになり距離Ｄの位置ずれが生じる。本発明のタッチパネル装置１３において、図１に示すように、可動側透明基板１の能動領域１ａを電極２が形成されていない対向する１対の辺を内側へ湾曲するＩＴＯ膜で形成することにより、電流が流れる方向（電極２と直交する方向）に対して、電極２に近い能動領域１ａの幅が広くなり、中央付近（電極２から遠いところ）の能動領域１ａの幅が狭くなることから、Ｒ＝ρ（Ｌ／ｗＴ）〔ただし、Ｒは能動領域１ａの抵抗値、ρは能動領域１ａの抵抗率、Ｌは能動領域１ａの長さ、ｗは能動領域１ａの幅、Ｔは能動領域１ａの厚み〕により、ρ、ＬおよびＴは定数であることから、Ｒはｗの値によって決定されるため、ｗの値が大きい電極２に近い場所ほど能動領域１ａの抵抗値が低くなり、ｗの値が小さい電極２から遠い場所ほど能動領域１ａの抵抗値が高くなる。これにより、図２に示すように、能動領域１ａの等電位線１ｂは電極２の近くになるに連れて間隔が狭くなる。また、表示装置１４の表示を正面から見たとき、図４（ｂ）に示すように、端部ほど見える表示の間隔が狭くなる。よって、表示装置１４の表示の間隔と能動領域１ａの等電位線１ｂの間隔を近似させることにより、位置ずれが抑制できる。   Here, the principle of misalignment that occurs when a conventional touch panel device is bent and the correction method of the touch panel device of the present invention will be described. As shown in FIG. 4, when the conventional touch panel device 100 is attached to the curved display device 14 with a distance t, the β point of the touch panel device 100 while viewing the button displayed at the α point of the display device 14. When the button is pressed, the γ point of the display device 14 is actually pressed and a positional deviation of the distance D occurs. In the touch panel device 13 of the present invention, as shown in FIG. 1, the active region 1a of the movable transparent substrate 1 is formed of an ITO film that curves inward with a pair of opposing sides where the electrodes 2 are not formed. The width of the active region 1a near the electrode 2 is widened and the width of the active region 1a near the center (away from the electrode 2) is narrowed with respect to the direction in which the current flows (direction perpendicular to the electrode 2). , R = ρ (L / wT) [where R is the resistance value of the active region 1a, ρ is the resistivity of the active region 1a, L is the length of the active region 1a, w is the width of the active region 1a, and T is active Since ρ, L, and T are constants depending on the thickness of the region 1a], R is determined by the value of w. Therefore, the resistance value of the active region 1a is lower as the position is closer to the electrode 2 having a larger value of w. , The farther away from the electrode 2, the smaller the value of w, the more active The resistance of the band 1a is high. As a result, as shown in FIG. 2, the equipotential lines 1 b of the active region 1 a become narrower as they become closer to the electrode 2. Further, when the display on the display device 14 is viewed from the front, as shown in FIG. Therefore, by approximating the display interval of the display device 14 and the interval of the equipotential lines 1b of the active region 1a, the positional deviation can be suppressed.

このように、本実施例に示すタッチパネル装置は、能動領域１ａを対向する１対の辺が内側へ湾曲するＩＴＯ膜で形成し、能動領域１ａの等電位線１ｂを端部に近づくに連れて間隔を狭くすることで位置ずれが抑制できるため、複雑な補正処理をすることなく従来と同様の構成で位置精度の向上を図ることができるという特徴を有している。   As described above, in the touch panel device shown in the present embodiment, the active region 1a is formed of an ITO film having a pair of opposing sides curved inward, and the equipotential line 1b of the active region 1a is approached to the end. Since the positional deviation can be suppressed by narrowing the interval, the positional accuracy can be improved with the same configuration as the conventional one without performing complicated correction processing.

本実施例では、凸方向に湾曲している表示装置に装着しているが、凹面方向に湾曲した表示装置に装着してもよく、種々の方法が考えられる。   In this embodiment, the display device is mounted on the display device curved in the convex direction. However, the display device may be mounted on the display device curved in the concave direction, and various methods are conceivable.

An active region 21a made of a rectangular ITO film is formed on the movable transparent substrate 21, and an electrode 22 made of Ag paste is formed on the opposite end of the active region 21a, and connected to the electrode 22 around the active region 21a. A drawing pattern 23 made of Ag paste is formed, and an adhesive paste 24 is disposed around the active region 21a. On the fixed-side transparent substrate 27, an active region 27a made of an ITO film having a pair of opposing sides curved, and an electrode 28 made of Ag paste are formed at opposite ends of the active region 27a in a direction orthogonal to the electrode 22 Then, a lead pattern 29 made of Ag paste connected to the electrode 28 is formed around the active region 27a, the dot spacer 26 is disposed on the active region 27a, and the insulating resist 25 is arranged around the active region 27a. It is installed.

可動側透明基板２１がドットスペーサ２６により一定の間隔をあけて固定側透明基板２７上に配置され、粘着糊２４によって固定される。このとき、引き回しパターン２３と２９が導電性接着剤（図示なし）でフレキシブルプリント基板３２に接続される。そして、コントロール基板３０に実装されたコネクタ３１にフレキシブルプリント基板３２を接続することで、タッチパネル装置が完成される。   The movable-side transparent substrate 21 is arranged on the fixed-side transparent substrate 27 at a predetermined interval by dot spacers 26 and fixed by the adhesive paste 24. At this time, the drawing patterns 23 and 29 are connected to the flexible printed circuit board 32 with a conductive adhesive (not shown). Then, the touch panel device is completed by connecting the flexible printed board 32 to the connector 31 mounted on the control board 30.

以上のように構成された本発明のタッチパネル装置は、図５のＹ方向に湾曲が可能であって、可動側透明基板２１の能動領域２１ａを押下すると、固定側透明基板２７の能動領域２７ａと接触し、測定された電圧値により押下した座標位置が決定される。固定側透明基板２７の能動領域２７ａを対向する１対の辺が内側へ湾曲するＩＴＯ膜で形成したため、湾曲させて使用しても表示装置の表示に合わせて押下した点とタッチパネル装置で検出される点の位置ずれを補正することができるため、位置ずれが抑制できる。位置ずれを抑制する原理については第１実施例と同様である。   The touch panel device of the present invention configured as described above can be bent in the Y direction of FIG. 5, and when the active area 21 a of the movable transparent substrate 21 is pressed, the active area 27 a of the fixed transparent substrate 27 The pressed coordinate position is determined by the touched voltage value measured. Since the active region 27a of the fixed-side transparent substrate 27 is formed of an ITO film having a pair of opposing sides curved inward, the touched point is detected by the touch panel device even if it is curved and used according to the display on the display device. Therefore, the positional deviation can be suppressed. The principle for suppressing the displacement is the same as in the first embodiment.

このように、本実施例に示すタッチパネル装置は、能動領域２７ａの等電位線２７ｂを端部に近づくに連れて間隔を狭くすることで位置ずれが抑制できるため、複雑な補正処理をすることなく従来と同様の構成で位置精度の向上を図ることができるという特徴を有している。   As described above, the touch panel device shown in this embodiment can suppress misalignment by narrowing the interval as the equipotential line 27b of the active region 27a approaches the end portion, so that complicated correction processing is not performed. It has a feature that the positional accuracy can be improved with the same configuration as the conventional one.

本実施例では、凸方向に湾曲している表示装置に装着しているが、凹面方向に湾曲した表示装置に装着してもよく、種々の方法が考えられる。   In this embodiment, the display device is mounted on the display device curved in the convex direction. However, the display device may be mounted on the display device curved in the concave direction, and various methods are conceivable.
