Description

本考案は、タッチパネルに関し、特に、配線構造が変更されたタッチパネルに関する。 The present invention relates to a touch panel, and more particularly to a touch panel with a changed wiring structure.

現在、家電市場において、タッチパネル（ｔｏｕｃｈｐａｎｅｌ）は、多機能携帯電話、携帯電話、タブレットコンピュータ、ノートパソコンなど、多くの製品に応用されている。タッチパネルは、斬新なマンマシンインターフェースであり、ユーザが指又はスタイラスを使用してモニターに表示されたオブジェクトに対して直接操作したり、コマンドを出したりすることができるため、利便性及び直感性に富む。 At present, in the home appliance market, touch panels are applied to many products such as multi-function mobile phones, mobile phones, tablet computers, and notebook computers. The touch panel is a novel man-machine interface that allows the user to directly operate on objects displayed on the monitor and issue commands using a finger or stylus, making it convenient and intuitive. Rich.

現在、頻繁に見られるタッチパネルの動作原理は、抵抗膜方式、静電容量方式、表面弾性波方式などである。タッチパネルは、一般に、表示領域と、表示領域周辺を取り囲む周辺領域とからなる。表示領域は、タッチ検出信号を生成するために用いられる。周辺領域内には、タッチ検出信号を信号処理機構に伝達して演算を行うために用いられる複数のリードが設置される。これにより、タッチ位置の座標を確定することができる。 At present, the operation principle of a touch panel that is frequently seen is a resistive film method, a capacitance method, a surface acoustic wave method, and the like. The touch panel generally includes a display area and a peripheral area surrounding the display area. The display area is used to generate a touch detection signal. In the peripheral area, a plurality of leads used for performing calculations by transmitting the touch detection signal to the signal processing mechanism are installed. Thereby, the coordinates of the touch position can be determined.

一般に、表示領域中の透明電極は、Ｘ方向及びＹ方向の電極からなる。図１を参照する。図１は、従来のタッチパネル１００の導電パターンを示す平面図である。図１に示すように、タッチパネル１００の表示領域１０１外側は、周辺領域１０３によって取り囲まれる。周辺領域１０３は、上側領域１０３ａ、下側領域１０３ｂ、右側領域１０３ｃ及び左側領域１０３ｄとからなる。 Generally, the transparent electrode in the display area is composed of electrodes in the X direction and the Y direction. Please refer to FIG. FIG. 1 is a plan view showing a conductive pattern of a conventional touch panel 100. As shown in FIG. 1, the outside of the display area 101 of the touch panel 100 is surrounded by a peripheral area 103. The peripheral area 103 includes an upper area 103a, a lower area 103b, a right area 103c, and a left area 103d.

タッチパネル１００の周辺領域１０３の上側領域１０３ａには、複数の周辺リード１０６が形成される。 A plurality of peripheral leads 106 are formed in the upper region 103 a of the peripheral region 103 of the touch panel 100.

タッチパネル１００の表示領域１０１上には、導電パターン１０４が形成される。導電パターン１０４は、複数の第１の電極１０４１、複数の第２の電極１０４２及び複数の間隔１０４３を有する。複数の第１の電極１０４１は、間隔１０４３をあけて配列される。各間隔１０４３には、複数の第２の電極１０４２が設置される。即ち、１つの第１の電極１０４１に複数の第２の第２の電極１０４２が組み合わされる。各間隔１０４３内の複数の第２の電極１０４２は、それぞれ電極導線１０４２１を有し、これら全ての電極導線１０４２１は、表示領域１０１から上側領域１０３ａまで延伸して上側領域１０３ａ上の周辺リード１０６にそれぞれ接続される。各第１の電極１０４１の上側端も、上側領域１０３ａ上の周辺リード１０６にそれぞれ接続される。
電極導線１０４２１と周辺リード１０６とが接続されることにより、電極から生成される検出信号は、処理機構（図示せず）に伝達される。 A conductive pattern 104 is formed on the display area 101 of the touch panel 100. The conductive pattern 104 includes a plurality of first electrodes 1041, a plurality of second electrodes 1042, and a plurality of intervals 1043. The plurality of first electrodes 1041 are arranged with an interval 1043 therebetween. A plurality of second electrodes 1042 are provided at each interval 1043. That is, a plurality of second second electrodes 1042 are combined with one first electrode 1041. Each of the plurality of second electrodes 1042 in each interval 1043 has an electrode lead wire 10421, and all the electrode lead wires 10421 extend from the display region 101 to the upper region 103a to the peripheral leads 106 on the upper region 103a. Each is connected. The upper end of each first electrode 1041 is also connected to the peripheral lead 106 on the upper region 103a.
By connecting the electrode lead wire 10421 and the peripheral lead 106, a detection signal generated from the electrode is transmitted to a processing mechanism (not shown).

しかし、上述の従来技術によるタッチパネルにおいては、各間隔１０４３内の第２の電極１０４２の電極導線１０４２１によって占められる広範囲の非検出領域Ａが形成されてしまう。即ち、全ての第２の電極１０４２の電極導線１０４２１が上側領域１０３ａに向かって敷設されるため、非検出領域Ａの幅が広くなる。これにより、導電パターン１０４の各アレイ間の距離が影響を受けるため、タッチ感度に劣る上、タッチパネル１００の特性上直線性に劣る。また、リードの接点数が多すぎるため、フレキシブル回路基板を接続する際の失敗率が高い。 However, in the touch panel according to the above-described conventional technology, a wide non-detection region A occupied by the electrode conductive wire 10421 of the second electrode 1042 in each interval 1043 is formed. That is, since the electrode conductors 10421 of all the second electrodes 1042 are laid toward the upper region 103a, the width of the non-detection region A is increased. Thereby, since the distance between each array of the conductive patterns 104 is affected, the touch sensitivity is inferior, and the touch panel 100 is inferior in linearity due to the characteristics. In addition, since the number of contact points of the lead is too large, the failure rate when connecting the flexible circuit board is high.

このため、業界においては、従来のタッチパネルの導電パターンに改良を加えることにより、非検出領域の幅及び空間を減少し、表示領域を最大化することが求められていた。 For this reason, the industry has been required to reduce the width and space of the non-detection area and maximize the display area by improving the conductive pattern of the conventional touch panel.

図２〜図５を参照する。図２〜図５を用いて本考案のタッチパネル２００の製造工程を順番に説明する。図２に示すように、先ず、タッチパネル２００内部の導電パターンを設置するベースとなる基板２０１を準備する。基板２０１は、シリカガラス、ポリメタクリル酸メチル（ＰＭＭＡ）、ポリカーボネート（ＰＣ）、ポリエチレンテレフタレート（ＰＥＴ）などからなる透明（透光）の板体である。基板２０１は、タッチパネル２００内部の導電線路を保護し、ユーザが指又はスタイラスでタッチ動作を行う平面（基板２０１の外表面）を提供するために用いられる。基板２０１は、タッチパネル２００内部の表示モジュール（ＬＣＤ表示モジュールなど）から放出される画像光を透過し、ユーザに画像を表示する。本実施形態のタッチパネル２００は、基板２０１の背面を俯瞰した視角から説明を行う。ここで、背面（内表面）とは、タッチパネル２００が使用される際にユーザが接触しない表面である。 Please refer to FIG. The manufacturing process of the touch panel 200 of the present invention will be described in order with reference to FIGS. As shown in FIG. 2, first, a substrate 201 serving as a base on which a conductive pattern inside the touch panel 200 is installed is prepared. The substrate 201 is a transparent (translucent) plate made of silica glass, polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), or the like. The substrate 201 is used to protect a conductive line inside the touch panel 200 and provide a plane (an outer surface of the substrate 201) on which a user performs a touch operation with a finger or a stylus. The substrate 201 transmits image light emitted from a display module (such as an LCD display module) inside the touch panel 200 and displays an image to the user. The touch panel 200 of the present embodiment will be described from a viewing angle obtained by looking down on the back surface of the substrate 201. Here, the back surface (inner surface) is a surface that the user does not contact when the touch panel 200 is used.

図２に示すように、基板２０１は、表示領域２０２と表示領域２０２外側に設けられる周辺領域とを具える。周辺領域は、表示領域２０２を囲んで図中下側から、第１の周辺領域２０３ａ、上方の第２の周辺領域２０３ｂ、左側の第３の周辺領域２０３ｃ及び右側の第４の周辺領域２０３ｄである。

That is, the first peripheral region 203a and the second peripheral region 203b are located on the first side of the display region 202 and the second side opposite to the first side with the display region interposed therebetween. The third peripheral region 203c and the fourth peripheral region 203d are respectively located on the third side of the display region and the fourth side located on the opposite side to the third side. The shielding layer (patterned mask layer) 204 corresponds to the positions of the first peripheral region 203a, the second peripheral region 203b, the third peripheral region 203c, and the fourth peripheral region 203d. The shielding layer 204 has a function of shielding and concealing the outer periphery of the display area 202. The shielding layer 204 of the present embodiment is opaque (translucent) and is formed by printing or applying a material that is an insulating material.

図３に示すように、基板２０１上に表示領域２０２、各周辺領域２０３ａ〜２０３ｄ及び遮蔽層２０４を形成後、タッチパネル２００内部の導電パターンの製作を行う。透明導電パターン２０５は、フォトエッチング又は他の方式によって表示領域２０２中に形成する。透明導電パターン２０５により、タッチパネル２００のタッチ領域が構成される。透明導電パターン２０５は、静電容量方式の電極とし、複数の縦方向の第１の電極２０５１と、該第１の電極２０５１の横に位置してこれと対を成す複数列の第２の電極２０５２とからなる。本実施形態の図中、これらの複数列の横方向の列に相当する複数の各第２の電極２０５２には、同一の符合を記す（例えば、横方向の第１列の電極の符合は、何れもＲＸ１と記す）。
複数の第１の電極２０５１が縦方向に間隔をあけて配列されることにより、表示領域２０２内には、複数の間隔２０６が画定される。即ち、各間隔２０６は、各２つの第１の電極２０５１間に位置する。複数の第２の電極２０５２は、第１の電極２０５１に相対して各間隔２０６内に設けられる。
また、各間隔２０６内の一部の第２の電極２０５２は、第１の電極導線２０５３ａを有し、残る第２の電極２０５２は、第２の電極導線２０５３ｂを有する。複数の第１の電極導線２０５３ａは、一方向（図中の下方）に向けて第１の周辺領域２０３ａまで延伸し、他方、複数の第２の電極導線２０５３ｂは、反対方向（図中の上方）に向けて第２の周辺領域２０３ｂまで延伸する。即ち、第２の電極の一部の電極導線（第１の電極導線２０５３ａ）と残りの電極導線（第２の電極導線２０５３ｂ）とは、互いに反対方向に延伸する。 As shown in FIG. 3, after forming the display area 202, the peripheral areas 203 a to 203 d and the shielding layer 204 on the substrate 201, a conductive pattern inside the touch panel 200 is manufactured. The transparent conductive pattern 205 is formed in the display area 202 by photoetching or other methods. The touch area of the touch panel 200 is configured by the transparent conductive pattern 205. The transparent conductive pattern 205 is an electrostatic capacitance type electrode, and includes a plurality of first electrodes 2051 in the vertical direction and a plurality of rows of second electrodes that are positioned beside the first electrodes 2051 and are paired therewith. 2052.

The first lead 2091 passes through the lower portion 208 and is connected to the first lead 2091 of the first peripheral lead structure 209.

図１３は、本考案の他の実施形態によるタッチパネルを示す平面図である。本実施形態によるタッチパネルの全体構造は、前述の実施形態と略同一であるため、同一の部材及び符合は、贅言しない。上述の実施形態と同一の部材は、本実施形態においても同一の符号を使用する。
図１３に示すように、本実施形態においては、第１の周辺領域２０３ａに第１の並列接続領域２０７が画定され、第２の周辺領域２０３ｂに画定される第２の並列接続領域３０７を有する。
第２の並列接続領域３０７は、複数の第２の絶縁部３０８及び第２の周辺リード構造３０９を有する。複数の第２の絶縁部３０８の一部は、複数の第２の電極導線２０５３ｂを被覆する。第２の絶縁部３０８は、多層のポリエステルフィルム又は無機材料である。
第２の周辺リード構造３０９は、第２の並列接続領域３０７に位置して、遮蔽層２０４上に設置され、第２の絶縁部３０８上に跨設される。第２の周辺リード構造３０９の材料及び製造工程は、第１の周辺リード構造２０９と同一である。
また、第２の周辺リード構造３０９は、複数の第３のリード３０９１、第４のリード３０９２及び第５のリード３０９３を有する。第３のリード３０９１は、一部の第２の電極導線２０５３ｂに接続される。第４のリード３０９２は、残りの第２の電極導線２０５３ｂに接続される。第５のリード３０９３は、複数の第１の電極２０５１に接続される。 FIG. 13 is a plan view illustrating a touch panel according to another embodiment of the present invention. Since the entire structure of the touch panel according to the present embodiment is substantially the same as that of the above-described embodiment, the same members and symbols are not exaggerated. The same members as those in the above embodiment use the same reference numerals in this embodiment.
As shown in FIG. 13, in the present embodiment, a first parallel connection region 207 is defined in the first peripheral region 203a, and a second parallel connection region 307 is defined in the second peripheral region 203b. .
The second parallel connection region 307 includes a plurality of second insulating portions 308 and a second peripheral lead structure 309. A part of the plurality of second insulating portions 308 covers the plurality of second electrode conductors 2053b. The second insulating portion 308 is a multilayer polyester film or an inorganic material.
The second peripheral lead structure 309 is located on the second parallel connection region 307, installed on the shielding layer 204, and straddled on the second insulating portion 308. The material and manufacturing process of the second peripheral lead structure 309 are the same as those of the first peripheral lead structure 209.
The second peripheral lead structure 309 includes a plurality of third leads 3091, fourth leads 3092, and fifth leads 3093. The third lead 3091 is connected to a part of the second electrode conductor 2053b. The fourth lead 3092 is connected to the remaining second electrode conductor 2053b. The fifth lead 3093 is connected to the plurality of first electrodes 2051.

さらに詳細に述べると、各間隔２０６内の縦方向同一列の横向きに対応する第２の電極２０５２（図１３中、縦方向第１列に対応する第２の電極２０５２は、ＲＸ１と記し、縦方向第２列〜第４列は、それぞれＲＸ２〜ＲＸ４と記す）の第２の電極導線２０５３ｂは、第３のリード３０９１及び第４のリード３０９２によって並列接続される。これにより、第２の電極導線２０５３ｂの接点数が減少する。 More specifically, the second electrode 2052 corresponding to the horizontal direction of the same vertical column in each interval 206 (in FIG. 13, the second electrode 2052 corresponding to the first vertical column is denoted as RX1, The second electrode conductors 2053b in the directions of the second column to the fourth column are indicated as RX2 to RX4, respectively, and are connected in parallel by the third lead 3091 and the fourth lead 3092. As a result, the number of contacts of the second electrode conductor 2053b decreases.

第２の絶縁部３０８は、第１の絶縁部２０８と同一のステップにより形成することができる。また、第２の周辺リード構造３０９は、第１の周辺リード構造２０９と同一のステップにより形成することができる。 The second insulating portion 308 can be formed by the same step as the first insulating portion 208. Further, the second peripheral lead structure 309 can be formed by the same steps as the first peripheral lead structure 209.

上述したことから分かるように、本考案のタッチパネルは、各間隔２０６内の第２の電極２０５２の第１の電極導線２０５３ａと第２の電極導線２０５３ｂとがそれぞれ上下方向に延伸し、下方の第１の周辺領域２０３ａと上方の第２の周辺領域２０３ｂとに分かれてそれぞれ至る。これにより、第１の電極と第の電極間の間隔２０６に第１の電極導線２０５３ａ及び第２の電極導線２０５３ｂを敷設するために形成される非検出領域Ａ’の幅が縮小される。本考案の非検出領域Ａ’と図１に示す従来技術の非検出領域Ａとを比較すると、本考案の非検出領域Ａ’は、従来技術の非検出領域Ａより、明確に幅が縮小されていることが分かる。これにより、基板２０１全体上における、透明導電パターン２０５の第１の電極２０５１及び第２の電極２０５２のアレイ配列が密集したものにできるため、タッチ感度及びタッチパネル特性の直線性を高めることができる。
また、第１の周辺リード構造２０９及び／又は第２の周辺リード構造３０９と、各間隔２０６内の同一列の第２の電極２０５２の第１の電極導線２０５３ａ及び／又は第２の電極導線２０５３ｂと、が並列接続されることにより、第１の周辺リード構造２０９及び第２の周辺リード構造３０９のリードの数を電極導線の数より少なくすることができる。リードの数が減少するため、リードの接点数も減少する。これにより、フレキシブル回路基板の寸法を縮小することができ、接点とフレキシブル回路基板との結合不良率を低減することができる。また、従来技術と比較し、本考案においては、銀ペーストによって第１の周辺リード構造２０９及び第２の周辺リード構造３０９が構成されるため、信号を伝送する際の抵抗を低減することができる。これにより、第１の電極導線２０５３ａ及び／又は第２の電極導線２０５３ｂから、第１の周辺リード構造２０９及び第２の周辺リード構造３０９に検出信号が伝送される際、信号の伝送速度が高まるため、タッチ感度を高めることができる。 As can be seen from the above, in the touch panel of the present invention, the first electrode conductor 2053a and the second electrode conductor 2053b of the second electrode 2052 in each interval 206 extend in the vertical direction, and the lower first One peripheral area 203a and an upper second peripheral area 203b are divided into the respective areas. Thereby, the width of the non-detection region A ′ formed for laying the first electrode conductor 2053a and the second electrode conductor 2053b in the interval 206 between the first electrode and the first electrode is reduced. Comparing the non-detection area A ′ of the present invention with the non-detection area A of the prior art shown in FIG. 1, the width of the non-detection area A ′ of the present invention is clearly reduced compared to the non-detection area A of the prior art. I understand that Thereby, since the array arrangement of the first electrode 2051 and the second electrode 2052 of the transparent conductive pattern 205 can be made dense on the entire substrate 201, the touch sensitivity and the linearity of the touch panel characteristics can be improved.
In addition, the first peripheral lead structure 209 and / or the second peripheral lead structure 309 and the first electrode conductor 2053a and / or the second electrode conductor 2053b of the second electrode 2052 in the same column within each interval 206 are provided. Are connected in parallel, the number of leads of the first peripheral lead structure 209 and the second peripheral lead structure 309 can be made smaller than the number of electrode conductors. Since the number of leads is reduced, the number of contact points of the leads is also reduced. Thereby, the dimension of a flexible circuit board can be reduced and the coupling failure rate of a contact and a flexible circuit board can be reduced. Compared with the prior art, in the present invention, since the first peripheral lead structure 209 and the second peripheral lead structure 309 are configured by silver paste, resistance when transmitting a signal can be reduced. . Accordingly, when a detection signal is transmitted from the first electrode lead wire 2053a and / or the second electrode lead wire 2053b to the first peripheral lead structure 209 and the second peripheral lead structure 309, the signal transmission speed is increased. Therefore, touch sensitivity can be increased.
