Description
本考案は、タッチパネルと液晶表示パネルとを結合させた構造に係り、特に、容量式タッチパネルと液晶表示パネルとの一体構造に関する。 The present invention relates to a structure in which a touch panel and a liquid crystal display panel are combined, and more particularly, to an integrated structure of a capacitive touch panel and a liquid crystal display panel.
液晶表示パネル(LCD)は、現在、広く利用されており、液晶表示パネルの構造には様々なものがある。図1および図2を同時に参照する。図1は、従来の液晶表示パネルを示す構造断面図である。図2は、従来の液晶表示モジュールを示す構造断面図である。図1および図2に示すように、従来の液晶表示パネル1は、液晶表示モジュール10および保護板11を含む。 Liquid crystal display panels (LCDs) are currently widely used, and there are various types of liquid crystal display panels. Please refer to FIG. 1 and FIG. 2 simultaneously. FIG. 1 is a structural cross-sectional view showing a conventional liquid crystal display panel. FIG. 2 is a structural sectional view showing a conventional liquid crystal display module. As shown in FIGS. 1 and 2, the conventional liquid crystal display panel 1 includes a liquid crystal display module 10 and a protection plate 11.
液晶表示モジュール10は、下偏光板12、下基板101、下導電層102、液晶層103、上導電層104、カラーフィルタ層13、上基板105および上偏光板14を含む。 The liquid crystal display module 10 includes a lower polarizing plate 12, a lower substrate 101, a lower conductive layer 102, a liquid crystal layer 103, an upper conductive layer 104, a color filter layer 13, an upper substrate 105, and an upper polarizing plate 14.
また従来、液晶表示パネルとタッチパネルとが組み合わされた操作が簡便な抵抗膜式タッチパネルにより位置を検出する方法があった。この抵抗膜式タッチパネルの位置検出方法には、表示装置の接触位置にタッチオブジェクトにより印加された接触圧を利用し、2層の抵抗膜を接触させてスイッチを閉じ、接触信号を制御装置に送信して処理を行い、接触位置を検出することができる抵抗膜式タッチパネルが初期に存在した。しかし、このタッチパネルは、抵抗膜が長期間繰り返し押圧されると変形または破損が発生し、タッチパネルの信頼性が低下する虞があった。 Conventionally, there has been a method of detecting a position by a resistive touch panel that is simple in operation in which a liquid crystal display panel and a touch panel are combined. In this method of detecting the position of the resistive touch panel, the contact pressure applied by the touch object is applied to the contact position of the display device, the two resistive films are brought into contact, the switch is closed, and the contact signal is transmitted to the control device. In the initial stage, there was a resistive touch panel capable of performing processing and detecting a contact position. However, this touch panel may be deformed or damaged when the resistance film is repeatedly pressed for a long period of time, which may reduce the reliability of the touch panel.
そのため、従来の抵抗膜式タッチパネルが有する欠点を改善することが可能な容量式タッチパネルが開発されている。この容量式タッチパネルの構造は、上下に配置されたそれぞれの電極パターン層と、各電極パターン層で挟設された誘電体とからなる。液晶表示パネルと容量式タッチパネルとを接合させるときは、一般に、液晶表示パネルと容量式タッチパネルとを先に別々に製作しておき、後で順次接合させて一体成形させていた。これにより、ユーザは、例えば、指、タッチペンなどの導電物を用いてタッチパネルの表面に表示された図案および文字に触って選択し、入力および操作を行っていた。 Therefore, capacitive touch panels that can improve the drawbacks of conventional resistive touch panels have been developed. The structure of this capacitive touch panel is composed of respective electrode pattern layers arranged above and below, and a dielectric sandwiched between the electrode pattern layers. In general, when a liquid crystal display panel and a capacitive touch panel are joined, the liquid crystal display panel and the capacitive touch panel are separately manufactured first, and then sequentially joined and integrally formed. As a result, the user touches a design and characters displayed on the surface of the touch panel using a conductive material such as a finger or a touch pen, for example, and performs input and operation.
しかし、タッチパネルおよび液晶表示パネルは、何れも表面に保護板を配置させる必要があった。また、一般にタッチパネルおよび液晶表示パネルの保護板が同じガラス材料で製造されるため、製造には多くの材料が重複して使用された。さらに、一般にタッチパネルと液晶表示パネルとを先に別々に製造してから、後で順次接合させるため、製造工程が複雑となる上に製造時間が浪費され、不良品が発生しやすかった。さらには、タッチパネルと液晶表示パネルとを別々に製造してから積層させる方式では、製品が厚くなり薄型化させることが困難であった。 However, both the touch panel and the liquid crystal display panel have to have a protective plate on the surface. Moreover, since the protective plate of a touch panel and a liquid crystal display panel is generally manufactured with the same glass material, many materials were used redundantly for manufacturing. Furthermore, since the touch panel and the liquid crystal display panel are generally manufactured separately and then sequentially joined later, the manufacturing process becomes complicated and manufacturing time is wasted, and defective products are likely to occur. Furthermore, in the method in which the touch panel and the liquid crystal display panel are separately manufactured and then laminated, it is difficult to make the product thicker and thinner.
本考案の目的は、容量式タッチパネルと液晶表示パネルとを一体構造に形成させる方式が、他に基板を追加する必要がないため、薄型化させることが可能な容量式タッチパネルと液晶表示パネルとの一体構造を提供することにある。 The purpose of the present invention is to form a capacitive touch panel and a liquid crystal display panel in an integrated structure, and it is not necessary to add another substrate. It is to provide a unitary structure.
上記課題を解決するために、本考案に係る容量式タッチパネルと液晶表示パネルとの一体構造は、液晶表示パネル、第1の電極層および第2の電極層を含む。液晶表示パネルは、下偏光板および上偏光板を有する液晶表示モジュールを含む。上偏光板の上に形成される第1の電極層は、所定の電極パターンを有し、上偏光板の下に形成される第2の電極層は、所定の電極パターンを有する。 In order to solve the above problems, an integrated structure of a capacitive touch panel and a liquid crystal display panel according to the present invention includes a liquid crystal display panel, a first electrode layer, and a second electrode layer. The liquid crystal display panel includes a liquid crystal display module having a lower polarizing plate and an upper polarizing plate. The first electrode layer formed on the upper polarizing plate has a predetermined electrode pattern, and the second electrode layer formed below the upper polarizing plate has a predetermined electrode pattern.
本実施形態において、液晶表示パネルと、上偏光板の上または下に形成された容量式パターン層とのみを含む。 In the present embodiment, only the liquid crystal display panel and the capacitive pattern layer formed on or below the upper polarizing plate are included.
上述したように、本考案の容量式タッチパネルと液晶表示パネルとの一体構造は、基板を増やす必要がないため全体の厚さが増大せず、製品の薄型化および軽量化を行うことができる。また、本考案では、容量式タッチパネルを液晶表示パネルと別々に生産してから組み立てるのではなく、直接、液晶表示パネルと接合させるため、製造工程が簡単であり、良品率が高くて製造コストが安価なため、加工性および生産性を向上させることができる。また、本考案の電極パターン層は、液晶表示パネルの上偏光板に接合され、ユーザの指またはタッチオブジェクトが接触する操作面に近いため、感度が高い。 As described above, the integrated structure of the capacitive touch panel and the liquid crystal display panel of the present invention does not require an increase in the number of substrates, so the overall thickness does not increase, and the product can be made thinner and lighter. In addition, in the present invention, since the capacitive touch panel is not manufactured separately from the liquid crystal display panel and then assembled, it is directly joined to the liquid crystal display panel, so the manufacturing process is simple, the yield rate is high, and the manufacturing cost is high. Since it is inexpensive, processability and productivity can be improved. In addition, the electrode pattern layer of the present invention is bonded to the upper polarizing plate of the liquid crystal display panel, and has a high sensitivity because it is close to the operation surface on which the user's finger or touch object comes into contact.
以下、考案の実施の形態を通じて本考案を説明するが、以下の実施形態は実用新案登録請求の範囲にかかる考案を限定するものではなく、また実施形態の中で説明されている特徴の組み合わせの全てが考案の解決手段に必須であるとは限らない。 Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the claims of the utility model registration, and are combinations of features described in the embodiments. Not all are essential to the solution of the idea.

図4を参照する。図4は、本考案の第1実施形態による容量式タッチパネルと液晶表示パネルとの一体構造100を示す分解斜視図である。図4に示すように、第1の電極層2は、互いに接触しないように平行に配列された複数の長尺状の電極21を有する所定の電極パターン20を含む。第2の電極層3は、互いに接触しないように平行に配列された長尺状の電極31を有する複数の電極パターン30を含む。第1の電極層2の各電極21および第2の電極層3の各電極31は、制御装置(図示せず)と電気的に接続されている。 Please refer to FIG. FIG. 4 is an exploded perspective view showing an integrated structure 100 of the capacitive touch panel and the liquid crystal display panel according to the first embodiment of the present invention. As shown in FIG. 4, the first electrode layer 2 includes a predetermined electrode pattern 20 having a plurality of elongated electrodes 21 arranged in parallel so as not to contact each other. The second electrode layer 3 includes a plurality of electrode patterns 30 having elongated electrodes 31 arranged in parallel so as not to contact each other. Each electrode 21 of the first electrode layer 2 and each electrode 31 of the second electrode layer 3 are electrically connected to a control device (not shown).
第1実施形態において、第1の電極層2の長尺状の各電極21と、第2の電極層3の長尺状の各電極31とは、互いに垂直に配列されている。第1の電極層2の電極21は、所定の軸方向Yの位置検出を行い、第2の電極層3の電極31は、所定の軸方向Xの位置検出を行う。しかし、他の実施形態では、第1の電極層2の電極21で軸方向Xの位置検出を行い、第2の電極層3の電極31で軸方向Yの位置検出を行ってもよい。 In the first embodiment, the long electrodes 21 of the first electrode layer 2 and the long electrodes 31 of the second electrode layer 3 are arranged perpendicular to each other. The electrode 21 of the first electrode layer 2 performs position detection in a predetermined axial direction Y, and the electrode 31 of the second electrode layer 3 performs position detection in a predetermined axial direction X. However, in another embodiment, the position in the axial direction X may be detected with the electrode 21 of the first electrode layer 2, and the position in the axial direction Y may be detected with the electrode 31 of the second electrode layer 3.
他の実施形態では、電極パターンの長尺状電極の電極は、菱形、正方形、正六角形など、様々な形状にしてもよい。図5を参照する。図5は、本考案の第2実施形態による容量式タッチパネルと液晶表示パネルとの一体構造100aを示す分解斜視図である。第2実施形態の第1の電極層2の電極パターン20a中の長尺状の各電極21は、六角形の幾何学形状である複数の電極22が接続されて形成されている。また、第2の電極層3の電極パターン30a中の長尺状の各電極31は、六角形の幾何学形状である複数の電極32が接続されて形成されたものである。 In other embodiments, the electrodes of the elongated electrodes of the electrode pattern may have various shapes such as rhombus, square, regular hexagon. Please refer to FIG. FIG. 5 is an exploded perspective view showing an integrated structure 100a of a capacitive touch panel and a liquid crystal display panel according to a second embodiment of the present invention. Each elongated electrode 21 in the electrode pattern 20a of the first electrode layer 2 of the second embodiment is formed by connecting a plurality of electrodes 22 having a hexagonal geometric shape. In addition, each elongated electrode 31 in the electrode pattern 30a of the second electrode layer 3 is formed by connecting a plurality of electrodes 32 having a hexagonal geometric shape.
ユーザがタッチオブジェクト(例えば、指またはその他の導電物)でタッチパネルに触ると、液晶表示パネル1中で第1の電極層2および第2の電極層3が制御装置(図示せず)に接続され、タッチオブジェクトが第1の電極層2および第2の電極層3にそれぞれ感応して容量結合が発生する。そして、電位が変化した信号が制御装置に送信され、対応した軸方向X、Yの位置が処理され、接触位置を検出することができる。 When the user touches the touch panel with a touch object (for example, a finger or other conductive material), the first electrode layer 2 and the second electrode layer 3 are connected to a control device (not shown) in the liquid crystal display panel 1. The touch object is sensitive to the first electrode layer 2 and the second electrode layer 3 to generate capacitive coupling. Then, a signal whose potential has changed is transmitted to the control device, the corresponding positions in the axial directions X and Y are processed, and the contact position can be detected.
図6および図7を同時に参照する。図6は、本考案の第3実施形態による容量式タッチパネルと液晶表示パネルとの一体構造100bを示す分解斜視図である。図7は、本考案の第3実施形態による容量式タッチパネルと液晶表示パネルとの一体構造100bの電極パターン層4を示す部分断面図である。第3実施形態は、容量式タッチパネルと液晶表示パネルとの一体構造100bが上偏光板14上に形成された電極パターン層4を含む点が異なる以外、第1実施形態と略同じである(同じ部材は、同じ符号で表されている)。 Please refer to FIG. 6 and FIG. 7 simultaneously. FIG. 6 is an exploded perspective view showing an integrated structure 100b of a capacitive touch panel and a liquid crystal display panel according to a third embodiment of the present invention. FIG. 7 is a partial cross-sectional view showing an electrode pattern layer 4 of an integrated structure 100b of a capacitive touch panel and a liquid crystal display panel according to a third embodiment of the present invention. The third embodiment is substantially the same as the first embodiment except that the integrated structure 100b of the capacitive touch panel and the liquid crystal display panel includes the electrode pattern layer 4 formed on the upper polarizing plate 14 (same as the first embodiment). The members are represented by the same reference numbers).
電極パターン層4は、複数の長尺状の第1の電極41および複数の長尺状の第2の電極42を有する所定の電極パターン40を含む。第1の電極41と第2の電極42とは、互いに交差するように非平行に配列され、第1の電極41と第2の電極42とが交差する箇所には絶縁層43が形成され(図7を参照する)、第2の電極42が第1の電極41に接触しないように跨設されている。第1の電極41および各第2の電極42のそれぞれには、六角形の幾何学形状である複数の電極411、421が接続されて形成されている。電極411、421は、タッチセンサの感度を向上させるために、六角形の幾何学形状にする。 The electrode pattern layer 4 includes a predetermined electrode pattern 40 having a plurality of long first electrodes 41 and a plurality of long second electrodes 42. The first electrode 41 and the second electrode 42 are arranged non-parallel so as to cross each other, and an insulating layer 43 is formed at a location where the first electrode 41 and the second electrode 42 intersect ( As shown in FIG. 7, the second electrode 42 is straddled so as not to contact the first electrode 41. A plurality of electrodes 411 and 421 having a hexagonal geometric shape are connected to each of the first electrode 41 and each second electrode 42. The electrodes 411 and 421 have a hexagonal geometric shape in order to improve the sensitivity of the touch sensor.
ユーザがタッチオブジェクト(例えば、指またはその他の導電物)でタッチパネルに触れると、タッチオブジェクトと接触された領域に対応した第1の電極41および第2の電極42との間で感応し、それぞれ容量結合が発生する。そして、接触された領域の大きさおよび位置に応じて電位が変化した信号が制御装置に送信される。これにより、第1の電極41および第2の電極42の軸方向X、Yに対応した信号と、接触された領域の大きさに対応した信号を基に、タッチオブジェクトの接触位置を判断することができる(図示せず)。 When the user touches the touch panel with a touch object (for example, a finger or other conductive material), the touch is sensed between the first electrode 41 and the second electrode 42 corresponding to the area in contact with the touch object. Bonding occurs. Then, a signal whose potential changes according to the size and position of the contacted area is transmitted to the control device. Thereby, the contact position of the touch object is determined based on the signals corresponding to the axial directions X and Y of the first electrode 41 and the second electrode 42 and the signal corresponding to the size of the contacted area. (Not shown).
図8を参照する。図8は、本考案の第4実施形態による容量式タッチパネルと液晶表示パネルとの一体構造100cを示す分解斜視図である。第4実施形態の容量式タッチパネルと液晶表示パネルとの一体構造100cは、電極パターン層4が上偏光板14の下に形成される点が異なる以外、第3実施形態と略同じである(同一の部材は、同一の符号で表されている)。また、第4実施形態の容量式タッチパネルと液晶表示パネルとの一体構造100cは、第3実施形態と同様に、タッチオブジェクトと、第1の電極41および第2の電極42との間に発生される容量結合により、接触位置を判断することができる。 Please refer to FIG. FIG. 8 is an exploded perspective view showing an integrated structure 100c of a capacitive touch panel and a liquid crystal display panel according to a fourth embodiment of the present invention. The integral structure 100c of the capacitive touch panel and the liquid crystal display panel of the fourth embodiment is substantially the same as that of the third embodiment except that the electrode pattern layer 4 is formed under the upper polarizing plate 14 (the same). Are indicated by the same reference numerals). Further, the integral structure 100c of the capacitive touch panel and the liquid crystal display panel of the fourth embodiment is generated between the touch object and the first electrode 41 and the second electrode 42, as in the third embodiment. The contact position can be determined by capacitive coupling.
