Description
本発明はタッチパネル付き表示装置を備える電子機器の入力表示面に貼り合わされる意匠板、およびタッチパネル入力表示機器に関する。
The present invention relates to a design board bonded to an input display surface of an electronic device including a display device with a touch panel, and a touch panel input display device.
近時、液晶等のディスプレイとタッチパネル等の入力部とが一体として構成された多機能携帯端末(いわゆる、スマートフォン)が知られている。このようなタッチパネルモジュールでは、静電気放電(Electric Discharge;ESD)から回路を保護するための効果的な対策が求められている。従来、例えば、以下の(1)~(4)に示すような静電気対策技術が知られている。
Recently, multifunctional mobile terminals (so-called smartphones) in which a display such as a liquid crystal display and an input unit such as a touch panel are integrally formed are known. In such a touch panel module, an effective measure for protecting a circuit from electrostatic discharge (ESD) is required. Conventionally, for example, countermeasures against static electricity as shown in the following (1) to (4) are known.
(1)特許文献1では、タッチパネルディスプレイを備える携帯電子機器の筐体において静電気対策のための導電部を設けることが提案されている。具体的には、特許文献1では、図10の(a)に示すように、携帯電子機器の筐体134が、タッチパネルモジュール120の外周部を覆うように形成されており、筐体134におけるタッチパネルモジュール120を覆う部分と、当該タッチパネルモジュール120との間に導電部130が設けられている。なお、図10において、符号110は、カバーガラスを示し、符号150は、液晶表示モジュールを表している。
(1) Patent Document 1 proposes to provide a conductive portion for countermeasures against static electricity in a casing of a portable electronic device including a touch panel display. Specifically, in Patent Document 1, as shown in FIG. 10A, the casing 134 of the portable electronic device is formed so as to cover the outer peripheral portion of the touch panel module 120, and the touch panel in the casing 134. A conductive portion 130 is provided between a portion covering the module 120 and the touch panel module 120. In FIG. 10, reference numeral 110 denotes a cover glass, and reference numeral 150 denotes a liquid crystal display module.
(2)特許文献2では、液晶表示装置において、カラーフィルタ基板上に透明電極層を形成し、導電材により、当該透明電極層とTFT基板とを電気的に接続することで、導電材を経由して、透明電極層からTFT基板側に静電気を逃すことが提案されている。
(2) In Patent Document 2, in a liquid crystal display device, a transparent electrode layer is formed on a color filter substrate, and the transparent electrode layer and the TFT substrate are electrically connected by a conductive material, thereby passing through the conductive material. Thus, it has been proposed to release static electricity from the transparent electrode layer to the TFT substrate side.
(3)図12に示すように、タッチパネルモジュール120のセンサーパターンの外周に静電気対策用の接地パターンを設ける。なお、図12に示す例では、タッチパネルモジュール120のためのメタル配線141に接地パターンが含まれており、フレキシブル基板142を介して、筐体に収納される本体基板側で接地される。
(3) As shown in FIG. 12, a grounding pattern for preventing static electricity is provided on the outer periphery of the sensor pattern of the touch panel module 120. In the example shown in FIG. 12, the metal wiring 141 for the touch panel module 120 includes a ground pattern, and is grounded via the flexible substrate 142 on the main body substrate side accommodated in the housing.
(4)図12および図13に示すように、筐体134において、タッチパネルモジュール120のセンサーパターン(122、123、141)よりも外側の位置に、インサートSUS(Steel Use Stainless)板金132の一部がセンサーパターン(122、123、141)側に露出するようにして設ける。これによりインサートSUS板金132を、静電気を接地GNDに導くための避雷針として利用する。なお、図13は、図12のA101-A101線における矢視断面図である。
(4) As shown in FIG. 12 and FIG. 13, a part of the insert SUS (SteeltainUsetainStainless) sheet metal 132 is provided at a position outside the sensor pattern (122, 123, 141) of the touch panel module 120 in the housing 134. Is exposed to the sensor pattern (122, 123, 141) side. Accordingly, the insert SUS sheet metal 132 is used as a lightning rod for guiding static electricity to the ground GND. 13 is a cross-sectional view taken along line A101-A101 in FIG.
また、この他の静電気対策として、筐体に、導電性の良い金属部材を採用したいわゆるマグキャビを使用することなどが挙げられる。
In addition, as another countermeasure against static electricity, a so-called mag-cavity employing a metal member having good conductivity can be used for the casing.
しかしながら、上述のような従来の静電気対策技術(1)~(4)には、それぞれ、次のような問題がある。
However, the conventional antistatic techniques (1) to (4) as described above have the following problems.
まず、(1)については、筐体の構造やデザインが限定される。すなわち、図10の(a)に示すように、筐体134は、導電部130を設けているためにタッチパネルモジュール120を覆うような構造でなければならない。また、このような構造を採用するため、カバーガラス110を設けなければ、電子機器全体の前面(紙面上側が前面側である)をフラットに構成することができない。
First, regarding (1), the structure and design of the housing are limited. That is, as shown in FIG. 10A, the housing 134 must have a structure that covers the touch panel module 120 because the conductive portion 130 is provided. In addition, since such a structure is employed, the front surface of the entire electronic device (the upper side on the paper surface is the front side) cannot be configured flat unless the cover glass 110 is provided.
また、(2)については、液晶表示装置における静電気対策しか想定されていない。図11を用いて、具体的に説明すると次のとおりである。タッチパネルの構造としては、例えば、図11の(a)、(b)および(c)に示すようなものが挙げられる。
For (2), only countermeasures against static electricity in liquid crystal display devices are assumed. This will be described in detail with reference to FIG. Examples of the structure of the touch panel include those shown in (a), (b), and (c) of FIG.
図11の(a)に示す構造は、カバーガラス110に、タッチパネルのセンサーパターン(122、123、141)を形成したものである。
The structure shown in FIG. 11A is obtained by forming a touch panel sensor pattern (122, 123, 141) on the cover glass 110. FIG.
図11の(b)に示す構造は、カバーガラス110とは別に、ガラス基板111を設け、当該ガラス基板111にタッチパネルのセンサーパターン(122、123、141)を形成した後、カバーガラス110と、センサーパターン形成後のガラス基板111とを張り合わせたものである。
In the structure shown in FIG. 11B, a glass substrate 111 is provided separately from the cover glass 110, and a touch panel sensor pattern (122, 123, 141) is formed on the glass substrate 111. The glass substrate 111 after the sensor pattern is formed is pasted together.
図11の(c)に示す構造は、液晶表示モジュール150の表示領域の表面にタッチパネルのセンサーパターン(122、123、141)を形成したタッチパネル付き液晶表示装置151と、カバーガラス110とから構成される構造である。
The structure shown in FIG. 11C includes a liquid crystal display device 151 with a touch panel in which a touch panel sensor pattern (122, 123, 141) is formed on the surface of the display area of the liquid crystal display module 150, and a cover glass 110. It is a structure.
つまり、(2)については、その適用の範囲が、図11の(c)に示したタッチパネル付き液晶表示装置または液晶表示装置単体に限定される。このため、(2)は、図11の(a)および(b)に示したような、その他の構造の場合における静電気対策として適用することができない。
That is, for (2), the range of application is limited to the liquid crystal display device with a touch panel shown in FIG. For this reason, (2) cannot be applied as a countermeasure against static electricity in the case of other structures as shown in (a) and (b) of FIG.
また、(3)については、静電気対策用の接地パターンが、センサーパターンのメタル配線と同じフレキシブル基板を経由して本体基板と配線されているため、静電気が接地パターンに対して放電したときに、当該フレキシブル基板で断線が発生する場合がある。
For (3), since the ground pattern for countermeasures against static electricity is wired to the main board via the same flexible substrate as the metal wiring of the sensor pattern, when static electricity is discharged to the ground pattern, Disconnection may occur in the flexible substrate.
また、フレキシブル基板での断線が発生しない場合でも、放電により、センサーパターンの断線や、タッチパネル制御用ICのフリーズが発生する場合がある。
In addition, even if the flexible substrate is not disconnected, the sensor pattern may be disconnected or the touch panel control IC may be frozen due to the discharge.
例えば、フレキシブル基板は、メタル配線等と比べれば、比較的抵抗が高い箇所となるので、接地パターンに対して放電した静電気が、フレキシブル基板に流れず、意図しない箇所に侵入するおそれがある。このため、接地パターンを設けていても、接地パターンに対して放電した静電気がセンサーパターンに侵入し、これによりセンサーパターンが破壊されるおそれがあった。
For example, since the flexible substrate has a relatively high resistance compared to a metal wiring or the like, static electricity discharged to the ground pattern may not flow into the flexible substrate and may enter an unintended location. For this reason, even if the ground pattern is provided, static electricity discharged with respect to the ground pattern may enter the sensor pattern, which may destroy the sensor pattern.
また、(4)については、インサートSUS板金には設計上の制約が多い。具体的には、次のとおりである。
For (4), insert SUS sheet metal has many design restrictions. Specifically, it is as follows.
例えば、防水性を十分に確保するために、インサートSUS板金を露出できない場合がある。
For example, in some cases, the insert SUS sheet metal cannot be exposed in order to ensure sufficient waterproofness.
また、筐体の小型化により、インサートSUS板金の露出には、高度な加工技術が必要となる傾向があり、このため製造ばらつきが生じてインサートSUS板金がきれいに露出しない場合がある。
Also, due to the downsizing of the casing, there is a tendency that advanced processing technology is required for the exposure of the insert SUS sheet metal. For this reason, manufacturing variations may occur and the insert SUS sheet metal may not be exposed cleanly.
また、インサートSUS板金の露出間隔Xに制約があるため、避雷針の防護効果が得られない箇所ができる。
Also, because the exposure interval X of the insert SUS sheet metal is limited, there are places where the lightning rod protection effect cannot be obtained.
具体的には、図12に示すインサートSUS板金の間隙X1において静電気が発生すると、インサートSUS板金およびセンサーパターンのうち、静電気が発生した箇所と近いほうに静電気が侵入する可能性が高い。
Specifically, when static electricity is generated in the gap X1 of the insert SUS sheet metal shown in FIG. 12, there is a high possibility that the static electricity will invade near the place where the static electricity is generated in the insert SUS sheet metal and the sensor pattern.
これらの設計上の制約は、スマートフォンをはじめ、完成品が狭額縁化するにつれて、より大きな制約となってきている。例えば、狭額縁化により、インサートSUS板金を露出することが難しいことも多い。
These design restrictions are becoming more restrictive as smartphones and other finished products become narrower. For example, it is often difficult to expose the insert SUS sheet metal by narrowing the frame.
他にもデザイン等の制約でマグキャビを使用することができない場合もある。理由としては、樹脂と比べて、マグキャビは製造コストが高くなる傾向があり、塗装の面でも制約が多い等が挙げられる。
マ グ There are also cases where it is not possible to use Magcavi due to design restrictions. The reason for this is that, compared to resin, magcavity tends to be expensive to manufacture, and there are many restrictions in terms of painting.
本発明は、上記の問題点に鑑みてなされたものであり、その目的は、多様な構造のタッチパネルに適用することができ、効果的に静電気対策がなされた意匠板等を実現することにある。

図2は、前面側から意匠板1を見た状況について示している。また、図2では、意匠板1の長手方向を紙面上下に対応させ、短手方向を紙面左右に対応させている。なお、図2では、説明の便宜上、図3および図1に示している一部部材を省略している。 (Plan view)
FIG. 2 shows a situation where thedesign plate 1 is viewed from the front side. Moreover, in FIG. 2, the longitudinal direction of the design board 1 is made to respond | correspond up and down on a paper surface, and the transversal direction is made to respond | correspond to paper surface right and left. In FIG. 2, for convenience of explanation, some members shown in FIGS. 3 and 1 are omitted.
図2は、前面側から意匠板1を見た状況について示している。また、図2では、意匠板1の長手方向を紙面上下に対応させ、短手方向を紙面左右に対応させている。なお、図2では、説明の便宜上、図3および図1に示している一部部材を省略している。 (Plan view)
FIG. 2 shows a situation where the
図2に示すように、意匠板1は、タッチパネルモジュールのセンサーパターン21と、センサーパターン21に電気的に接続されるメタル配線(センサー信号導通配線)41と、メタル配線41と電気的に接続されフレキシブル基板(可動基板)42と、メタル配線41の外周に設けられるメタル配線(導通配線)43とを備える構成である。また、意匠板1には、液晶表示装置の表示領域を視認できるようにするための窓部40が設けられている。
As shown in FIG. 2, the design board 1 is electrically connected to the sensor pattern 21 of the touch panel module, the metal wiring (sensor signal conduction wiring) 41 electrically connected to the sensor pattern 21, and the metal wiring 41. In this configuration, a flexible substrate (movable substrate) 42 and a metal wiring (conductive wiring) 43 provided on the outer periphery of the metal wiring 41 are provided. Further, the design plate 1 is provided with a window portion 40 so that the display area of the liquid crystal display device can be visually recognized.
センサーパターン21は、センサーパターン21上の指やタッチペン等の接触位置を検出するための透明電極(後述)が配置される。センサーパターン21の透明電極には、例えば、ITO(Indium Tin Oxide)部材等を用いることができる。また、接触位置の検出方式としては、例えば、投影静電容量方式を採用することができる。しかしながら、これに限られず、従来知られている任意の検出方式を採用することができる。
The sensor pattern 21 is provided with a transparent electrode (described later) for detecting a contact position of a finger or a touch pen on the sensor pattern 21. For the transparent electrode of the sensor pattern 21, for example, an ITO (Indium Tin Oxide) member or the like can be used. As a contact position detection method, for example, a projected capacitance method can be adopted. However, the present invention is not limited to this, and any conventionally known detection method can be employed.
なお、電子機器の組み立て工程では、液晶表示装置(不図示)が、意匠板1の背面(すなわち、図2の紙面奥手、図3、4の紙面下方向)に配置される。センサーパターン21は、光を透過させるため、窓部40を通じて液晶表示装置の表示領域が視認可能となる。また、窓部40は、透明なガラス部材またはアクリル部材により構成してもよいし、開口部として構成してもよい。
In the assembly process of the electronic device, a liquid crystal display device (not shown) is disposed on the back surface of the design board 1 (that is, on the back side of the paper in FIG. 2 and in the downward direction on the paper in FIGS. 3 and 4). Since the sensor pattern 21 transmits light, the display area of the liquid crystal display device can be visually recognized through the window 40. Moreover, the window part 40 may be comprised with a transparent glass member or an acrylic member, and may be comprised as an opening part.
また、図2に示すように、センサーパターン21を取り囲むように額縁状に、メタル配線41が設けられる。
Further, as shown in FIG. 2, a metal wiring 41 is provided in a frame shape so as to surround the sensor pattern 21.
メタル配線41には、本体基板(図2において不図示)と接続するためのフレキシブル基板42が電気的に接続されている。センサーパターン21の検出信号は、メタル配線41、フレキシブル基板42、および本体基板の順に伝送される。
The metal wiring 41 is electrically connected to a flexible substrate 42 for connection to a main body substrate (not shown in FIG. 2). The detection signal of the sensor pattern 21 is transmitted in the order of the metal wiring 41, the flexible substrate 42, and the main body substrate.
なお、メタル配線41は、静電気対策のための接地配線が含まれており、フレキシブル基板42を経由してタッチパネルの制御基板(以下、本体基板と称する)の接地電位と接続される。言い換えれば、上記接地配線は、センサーパターン21に接続されているメタル配線と併設されており、両者ともにフレキシブル基板42に接続されている。
The metal wiring 41 includes a ground wiring for countermeasures against static electricity, and is connected to a ground potential of a control board (hereinafter referred to as a main body board) of the touch panel via the flexible board 42. In other words, the ground wiring is provided side by side with the metal wiring connected to the sensor pattern 21, and both are connected to the flexible substrate 42.
このため、メタル配線41に含まれる接地配線に侵入した静電気は、フレキシブル基板42を経由して本体基板の接地電位に放電される。
For this reason, static electricity that has entered the ground wiring included in the metal wiring 41 is discharged to the ground potential of the main body substrate via the flexible substrate 42.
メタル配線43は、メタル配線41を取り囲むように額縁状に設けられている。メタル配線43の外周外側には、少なくとも一部において、メタル配線43を突出させて突出部43pが設けられる。図2では、紙面左下および右下の部分に突出部43pが設けられている。
The metal wiring 43 is provided in a frame shape so as to surround the metal wiring 41. At least a part of the outer periphery of the metal wiring 43 is provided with a protruding portion 43 p that protrudes the metal wiring 43. In FIG. 2, protrusions 43p are provided at the lower left and lower right portions of the drawing.
図2では、意匠板1の短辺部分のうち、メタル配線43の突出部43pを設ける箇所を符号1eにて示している(以下、短辺部分(幅広部)1eと称する)。
In FIG. 2, a portion of the short side portion of the design plate 1 where the protruding portion 43p of the metal wiring 43 is provided is indicated by reference numeral 1e (hereinafter referred to as a short side portion (wide portion) 1e).
突出部43pは、このように短辺部分1eにおいて設けることが好ましい。いいかえれば、突出部43pは、長手方向に突出させることが望ましい。その理由は、短手方向(すなわち、長辺部分(幅狭部))は、狭額縁化のためこのような突出部43pを設けるのに十分なスペースがない場合が多いからである。しかしながら、図2に示す例は、単なる実施例であり、これに限られず、スペース的に可能であれば、短手方向に突出部43pを設けてもよい。
The protrusion 43p is preferably provided in the short side portion 1e as described above. In other words, it is desirable that the protrusion 43p protrude in the longitudinal direction. The reason is that the short direction (that is, the long side portion (narrow portion)) often does not have enough space to provide such a protrusion 43p for narrowing the frame. However, the example shown in FIG. 2 is merely an example, and the present invention is not limited to this example. If space is possible, the protrusion 43p may be provided in the short direction.
(断面図1)
次に、図3を用いて、図2に示すA1-A1線における断面構造について説明する。図3において紙面上側が、意匠板1(あるいは電子機器)の前面である。また、以下の図3の説明では、矢印A10の向きを上と表現する。矢印A10の向きと電子機器の前面方向は対応している。 (Cross sectional view 1)
Next, a cross-sectional structure taken along line A1-A1 shown in FIG. 2 will be described with reference to FIG. In FIG. 3, the upper side of the drawing is the front surface of the design plate 1 (or electronic device). In the following description of FIG. 3, the direction of the arrow A10 is expressed as “up”. The direction of the arrow A10 corresponds to the front direction of the electronic device.

Next, a cross-sectional structure taken along line A1-A1 shown in FIG. 2 will be described with reference to FIG. In FIG. 3, the upper side of the drawing is the front surface of the design plate 1 (or electronic device). In the following description of FIG. 3, the direction of the arrow A10 is expressed as “up”. The direction of the arrow A10 corresponds to the front direction of the electronic device.
図3に示すように、筐体34の上に、意匠板1が、両面テープ(防水テープ)33により貼り合わされる。両面テープ33としては、例えば、防水性のものを採用することができる。
As shown in FIG. 3, the design plate 1 is bonded onto the housing 34 with a double-sided tape (waterproof tape) 33. As the double-sided tape 33, for example, a waterproof one can be adopted.
意匠板1は、最前面のカバーガラス10に、センサーパターン21を含むタッチパネル層45が形成されてなる構成である。
The design plate 1 has a configuration in which a touch panel layer 45 including the sensor pattern 21 is formed on the front cover glass 10.
センサーパターン21は、センサーパターン21上のタッチ接触位置のX座標を検出するための透明電極21aおよびY座標を検出するための透明電極21bを含む。透明電極21aおよび透明電極21bは、それぞれタッチパネル層45のカバーガラス10側に配置される。なお、ここでは、電子機器の短手方向をX軸方向とし、長手方向をY軸方向としている。
The sensor pattern 21 includes a transparent electrode 21a for detecting the X coordinate of the touch contact position on the sensor pattern 21 and a transparent electrode 21b for detecting the Y coordinate. The transparent electrode 21a and the transparent electrode 21b are disposed on the cover glass 10 side of the touch panel layer 45, respectively. Here, the short direction of the electronic device is the X-axis direction, and the long direction is the Y-axis direction.
透明電極21bは、メタル配線41と電気的に接続される。また、透明電極21aおよび21bは、絶縁層22および24によって絶縁される。
The transparent electrode 21b is electrically connected to the metal wiring 41. The transparent electrodes 21a and 21b are insulated by the insulating layers 22 and 24.
また、メタル配線41の外側(紙面左方向)には、メタル配線43が設けられる。また、メタル配線41およびメタル配線43は、カバーガラス10に近い側に設けられる絶縁層22およびカバーガラス10から遠い側に設けられる絶縁層24の層間に設けられている。
Further, a metal wiring 43 is provided outside the metal wiring 41 (in the left direction in the drawing). The metal wiring 41 and the metal wiring 43 are provided between the insulating layer 22 provided on the side close to the cover glass 10 and the insulating layer 24 provided on the side far from the cover glass 10.
また、タッチパネル層45の前面(カバーガラス10側)では、センサーパターン21の外側の外周部(すなわち、センサーパターン21より紙面左側)において、ブラックマトリクス層25が設けられる。このようにブラックマトリクス層25により遮光することで、メタル配線41およびメタル配線43を、外部から隠蔽している。
Further, on the front surface (the cover glass 10 side) of the touch panel layer 45, the black matrix layer 25 is provided on the outer peripheral portion of the sensor pattern 21 (that is, the left side of the sensor pattern 21). Thus, the metal wiring 41 and the metal wiring 43 are concealed from the outside by being shielded by the black matrix layer 25.
また、タッチパネル層45の背面(カバーガラス10と逆の側)では、センサーパターン21の外側の外周部において、ブラックインク26が塗布され、前面と同様に遮光される。
Further, on the back surface (the side opposite to the cover glass 10) of the touch panel layer 45, the black ink 26 is applied on the outer periphery of the sensor pattern 21 and is shielded in the same manner as the front surface.
なお、上述のとおり、電子機器の組み立て工程において、液晶表示装置が、意匠板1の背面(図3の符号P1に示す位置)に配置されても構わない。
As described above, in the electronic device assembly process, the liquid crystal display device may be disposed on the back surface of the design plate 1 (position indicated by reference numeral P1 in FIG. 3).
(断面図2)
次に、図1を用いて、図2に示すA2-A2線における断面構造について説明する。図1においても、図3と同様、紙面上側が、意匠板1(あるいは電子機器)の前面である。また、矢印A10の向きを上と表現する。矢印A10の向きと電子機器の前面方向は対応している。 (Cross sectional view 2)
Next, a cross-sectional structure taken along line A2-A2 shown in FIG. 2 will be described with reference to FIG. In FIG. 1, as in FIG. 3, the upper side of the drawing is the front surface of the design board 1 (or electronic device). The direction of the arrow A10 is expressed as “up”. The direction of the arrow A10 corresponds to the front direction of the electronic device.
次に、図1を用いて、図2に示すA2-A2線における断面構造について説明する。図1においても、図3と同様、紙面上側が、意匠板1(あるいは電子機器)の前面である。また、矢印A10の向きを上と表現する。矢印A10の向きと電子機器の前面方向は対応している。 (Cross sectional view 2)
Next, a cross-sectional structure taken along line A2-A2 shown in FIG. 2 will be described with reference to FIG. In FIG. 1, as in FIG. 3, the upper side of the drawing is the front surface of the design board 1 (or electronic device). The direction of the arrow A10 is expressed as “up”. The direction of the arrow A10 corresponds to the front direction of the electronic device.
図1に示すように、突出部43pは、絶縁層22および絶縁層24の層間に設けられる。
As shown in FIG. 1, the protrusion 43 p is provided between the insulating layer 22 and the insulating layer 24.
突出部43pは、図3に示したメタル配線43に比べて、やや意匠板1の中心寄り(紙面右側)に配置されている。このため、突出部43pは、両面テープ33よりも内側の領域(紙面右側)に配置されている。
The protrusion 43p is disposed slightly closer to the center of the design board 1 (right side of the drawing) than the metal wiring 43 shown in FIG. For this reason, the protrusion 43p is disposed in an inner region (right side of the drawing) than the double-sided tape 33.
また、突出部43pから、タッチパネル層45の背面にかけて、開口部OP1が設けられる。いいかえれば、突出部43pが配置されている位置において、絶縁層24から、ブラックインク26にかけて開口部OP1が設けられる。また、開口部OP1は、例えば、次の工程により形成することができる。すなわち、ブラックインク26の塗布工程、および、絶縁層24の形成工程において、予め開口部OP1に相当する部分に保護膜(レジスト)を形成しておく。そして、工程後に当該保護膜を剥離することで、保護膜が形成されていた部分に開口部OP1を形成することができる。
Further, an opening OP1 is provided from the protrusion 43p to the back surface of the touch panel layer 45. In other words, the opening OP1 is provided from the insulating layer 24 to the black ink 26 at the position where the protrusion 43p is disposed. Further, the opening OP1 can be formed by the following process, for example. That is, in the application process of the black ink 26 and the formation process of the insulating layer 24, a protective film (resist) is formed in a portion corresponding to the opening OP1 in advance. Then, by removing the protective film after the process, the opening OP1 can be formed in the portion where the protective film has been formed.
また、筐体34において、突出部43pと対向する位置には、インサートSUS板金(接地部)32が設けられている。このインサートSUS板金32は本体基板(不図示)に設けられる接地電位GNDと電気的に接続される。なお、本体基板を配置する位置は、筐体の形状に応じて任意に設計することができる。例えば、本体基板は、図1において、符号P2に示す位置に配置されていてもよい。また、このような配置において、意匠板1と本体基板との間に仕切りが設けられていてもよい。
In the housing 34, an insert SUS sheet metal (grounding portion) 32 is provided at a position facing the protruding portion 43p. The insert SUS sheet metal 32 is electrically connected to a ground potential GND provided on a main body substrate (not shown). The position where the main body substrate is arranged can be arbitrarily designed according to the shape of the housing. For example, the main body substrate may be disposed at a position indicated by reference sign P2 in FIG. In such an arrangement, a partition may be provided between the design plate 1 and the main body substrate.
また、ここでは、筐体34にインサートSUS板金32を設けて本体基板の接地電位GNDと接続する構成としたがこれに限られない。セット側のいずれかの場所に接地電位GNDが設けられていればよく、この接地電位GNDが突出部43pと、導通部材31を介して接続可能となっていればよい。
In this case, the insert SUS sheet metal 32 is provided in the housing 34 and connected to the ground potential GND of the main body substrate, but the present invention is not limited to this. It is only necessary that the ground potential GND is provided at any place on the set side, and it is only necessary that the ground potential GND can be connected to the protruding portion 43p via the conductive member 31.
また、突出部43pと、インサートSUS板金32とは、導通部材31によって電気的に接続される。導通部材31としては、例えば、ガスケット等の導電性貼物を用いることができる。言い換えれば、導通部材31は、ブラックインク26および絶縁層24に設けられた開口部OP1に挿入されることで、突出部43pと、インサートSUS板金32とを電気的に接続する。
Further, the protruding portion 43p and the insert SUS sheet metal 32 are electrically connected by the conductive member 31. As the conductive member 31, for example, a conductive paste such as a gasket can be used. In other words, the conductive member 31 is inserted into the opening OP1 provided in the black ink 26 and the insulating layer 24, thereby electrically connecting the protrusion 43p and the insert SUS sheet metal 32.
なお、図2に示すメタル配線43において、紙面左下に位置する突出部43pと紙面右下に位置する突出部43pとは線Lに対して対称的に構成することができる。
In the metal wiring 43 shown in FIG. 2, the protrusion 43p located at the lower left side of the drawing and the protrusion 43p located at the lower right of the drawing can be configured symmetrically with respect to the line L.
また、以上では、メタル配線43は、メタル配線41の全周囲を取り囲む閉じた配線であったが、これに限られない。メタル配線43は、所望の静電気対策効果を得られる範囲で開いた配線として配置することができる。例えば、“コ”の字型のように、配線の両端部がつながっていない構成することも可能である。また、この場合、配線の両端部において、突出部43pを設けることが好ましい。
In the above description, the metal wiring 43 is a closed wiring that surrounds the entire periphery of the metal wiring 41, but is not limited thereto. The metal wiring 43 can be arranged as an open wiring within a range where a desired antistatic effect can be obtained. For example, a configuration in which both ends of the wiring are not connected, such as a “U” shape, is possible. In this case, it is preferable to provide the protrusions 43p at both ends of the wiring.

以下において、図4~9を用いて、意匠板1の変形例について説明する。 (Modification)
Hereinafter, modified examples of thedesign plate 1 will be described with reference to FIGS.
以下において、図4~9を用いて、意匠板1の変形例について説明する。 (Modification)

以上では、センサーパターン21と接続するメタル配線41に含まれる接地配線と、接地パターンとしてのメタル配線43とを別個に構成したが、これらを共通化した構成も可能である。本変形例1は、このような構成の具体例について説明する。 (Modification 1)
In the above, the ground wiring included in themetal wiring 41 connected to the sensor pattern 21 and the metal wiring 43 as the ground pattern are separately configured, but a configuration in which these are shared is also possible. In the first modification, a specific example of such a configuration will be described.
以上では、センサーパターン21と接続するメタル配線41に含まれる接地配線と、接地パターンとしてのメタル配線43とを別個に構成したが、これらを共通化した構成も可能である。本変形例1は、このような構成の具体例について説明する。 (Modification 1)
In the above, the ground wiring included in the
図4および図5を用いて、本変形例1に係るメタル配線41、およびメタル配線41の突出部41pの具体的な形状の例について説明する。
Examples of specific shapes of the metal wiring 41 and the protrusion 41p of the metal wiring 41 according to the first modification will be described with reference to FIGS.
図4は、意匠板1を背面から見た外観図である。すなわち、図4は、図1、図3に示す矢印10の方向に意匠板1の背面を見た外観図である。図5は、図4における領域R1の詳細を拡大して表した図である。なお、図4では、本体基板に接続するためのフレキシブル基板の記載を省略している。
FIG. 4 is an external view of the design board 1 as viewed from the back. That is, FIG. 4 is an external view of the back surface of the design plate 1 in the direction of the arrow 10 shown in FIGS. FIG. 5 is an enlarged view showing details of the region R1 in FIG. In FIG. 4, the description of a flexible substrate for connecting to the main body substrate is omitted.
図4に示すように、意匠板1のメタル配線41において、4つの突出部41p(41A~41D)を設ける構成であってもよい。メタル配線41は、最も外周側に接地配線を含む。突出部41A~41Dは、メタル配線41の接地配線を外周外側に突出させて設けることができる。
As shown in FIG. 4, the metal wiring 41 of the design plate 1 may be provided with four projecting portions 41p (41A to 41D). The metal wiring 41 includes a ground wiring on the outermost periphery side. The projecting portions 41A to 41D can be provided by projecting the ground wiring of the metal wiring 41 to the outer periphery.
上記構成の場合、突出部41A~41Dは、図4に示すように、額縁状に配置されたメタル配線41の短辺の外周外側に設けてもよい。すなわち、突出部41A~41Dは、ベゼル(枠)の短辺に設けてもよい。
In the case of the above configuration, the protrusions 41A to 41D may be provided outside the outer periphery of the short side of the metal wiring 41 arranged in a frame shape as shown in FIG. That is, the protrusions 41A to 41D may be provided on the short side of the bezel (frame).
図4に示す意匠板1では、ベゼルの長辺の幅Nが、ベゼルの短辺の幅W1,W2よりも狭くなっている。そこで、ベゼルの長辺よりも幅が広く、スペース的に余裕のあるベゼルの短辺に突出部を設けている。すなわち、紙面左側のベゼルの短辺において、突出部41Bおよび41Cを設け、紙面右側のベゼルの短辺において、突出部41Aおよび41Dを設けている。
In the design plate 1 shown in FIG. 4, the width N of the long side of the bezel is narrower than the widths W1 and W2 of the short side of the bezel. Therefore, the protrusion is provided on the short side of the bezel that is wider than the long side of the bezel and has a sufficient space. That is, protrusions 41B and 41C are provided on the short side of the bezel on the left side of the paper, and protrusions 41A and 41D are provided on the short side of the bezel on the right side of the paper.
続いて、図5を用いて、図4の領域R1の詳細について説明する。図5に突出部41Aの詳細な形状の一例を示している。図5に示すように、突出部41Aは、メタル配線41の接地配線が長辺方向に延長され、内側方向に屈曲されて、さらにその先端部で矩形に形成されることにより構成される。また、突出部41の矩形部分に合わせて、開口部OP1が設けられる。
Subsequently, the details of the region R1 in FIG. 4 will be described with reference to FIG. FIG. 5 shows an example of the detailed shape of the protruding portion 41A. As shown in FIG. 5, the protrusion 41 </ b> A is configured by extending the ground wiring of the metal wiring 41 in the long side direction, bending the metal wiring 41 in the inner direction, and further forming a rectangular shape at the tip portion. In addition, an opening OP <b> 1 is provided in accordance with the rectangular portion of the protrusion 41.
なお、例示的には、メタル配線41の短辺の幅L1は、数十マイクロメートルであり、突出部41Aの幅L2は、1000マイクロメートル程度である。このため、突出部41Aは、視認できるオーダーの大きさであり、意匠板1と、筐体34とを組み立てる工程における位置合わせは比較的容易である。すなわち、開口部OP1に導通部材31を挿入し、意匠板1と筐体34とを貼りあわせるための位置合わせが容易となる。
For example, the width L1 of the short side of the metal wiring 41 is several tens of micrometers, and the width L2 of the protruding portion 41A is about 1000 micrometers. For this reason, the protruding portion 41 </ b> A has an order size that can be visually recognized, and alignment in the process of assembling the design plate 1 and the housing 34 is relatively easy. That is, alignment for inserting the conductive member 31 into the opening OP1 and bonding the design plate 1 and the housing 34 becomes easy.
また、図2では、フレキシブル基板の近傍に突出部43pを設けることが好ましい。例えば、フレキシブル基板の両脇に突出部43pを二つ設けてもよい。これにより、フレキシブル基板に静電気が浸入することを防ぐことができる。

(作用・効果)
以上に示したように、本発明に係る意匠板1は、表示装置またはタッチパネル付き表示装置を含む部品と組み合わされて電子機器を構成する。上記部品には、電子機器の筐体、制御基板、通信モジュールその他の部品が含まれる。この電子機器は、タッチパネル入力表示機器である。意匠板1は、タッチパネル入力表示機器に搭載される表示装置またはタッチパネル付き表示装置と貼り合わされる。 (Action / Effect)
As described above, thedesign board 1 according to the present invention is combined with a component including a display device or a display device with a touch panel to constitute an electronic device. The above components include electronic equipment casings, control boards, communication modules, and other components. This electronic device is a touch panel input display device. The design plate 1 is bonded to a display device mounted on a touch panel input display device or a display device with a touch panel.
以上に示したように、本発明に係る意匠板1は、表示装置またはタッチパネル付き表示装置を含む部品と組み合わされて電子機器を構成する。上記部品には、電子機器の筐体、制御基板、通信モジュールその他の部品が含まれる。この電子機器は、タッチパネル入力表示機器である。意匠板1は、タッチパネル入力表示機器に搭載される表示装置またはタッチパネル付き表示装置と貼り合わされる。 (Action / Effect)
As described above, the
図11の(a)~(c)に、タッチパネルの構造の類型について示したが、本発明に係る意匠板1は、上述したように、広く多様な類型に適用することができる。
11A to 11C show the types of the structure of the touch panel, but the design plate 1 according to the present invention can be applied to a wide variety of types as described above.
すなわち、図1~3に示すように、意匠板1にタッチパネルのセンサーパターン21が設けられていてもよい。また、図6および8に示すように、意匠板1と、タッチパネルモジュール20が貼り合わされる構成であってもよい。また、図8および図9に示すように、意匠板1と、タッチパネル付き液晶表示モジュール51が貼り合わされる構成であってもよい。
That is, as shown in FIGS. 1 to 3, a touch panel sensor pattern 21 may be provided on the design plate 1. Moreover, as shown in FIGS. 6 and 8, the design plate 1 and the touch panel module 20 may be bonded together. Moreover, as shown in FIG. 8 and FIG. 9, the structure by which the design board 1 and the liquid crystal display module 51 with a touch panel are bonded together may be sufficient.
また、意匠板1は、液晶表示装置の表示領域を視認可能に設けられる窓部40と、意匠板1における、表示面との貼り合わせ面に、窓部40の外周を囲むように設けられる、周囲を絶縁されたメタル配線43と、メタル配線43の少なくとも一部にて、上記外周外側に該メタル配線43を突出させて設けられる突出部43pと、上記電子機器にて、突出部43と対向して設けられるインサートSUS板金32との間を電気的に接続するための導通部材31を挿入するために上記メタル配線43を絶縁する部分である絶縁層24およびブラックインク26に設けられる開口部OP1と、を有する。
Moreover, the design board 1 is provided so that the outer periphery of the window part 40 may be enclosed in the bonding surface with the window part 40 provided so that the display area of a liquid crystal display device can be visually recognized, and the display surface in the design board 1. The metal wiring 43 that is insulated from the periphery, the projecting portion 43p provided by projecting the metal wiring 43 outside the outer periphery at least at a part of the metal wiring 43, and the projecting portion 43 facing the electronic device An opening OP1 provided in the insulating layer 24 and the black ink 26, which is a portion that insulates the metal wiring 43 in order to insert the conductive member 31 for electrically connecting the insert SUS sheet metal 32. And having.
なお、上記メタル配線43は、タッチパネルのセンサーパターン21と接続されるメタル配線41とは別個に設けられていてもよい。また、図4および図5に示すようにメタル配線41に共通化されていてもよい。
The metal wiring 43 may be provided separately from the metal wiring 41 connected to the sensor pattern 21 of the touch panel. Further, as shown in FIGS. 4 and 5, the metal wiring 41 may be shared.
上記構成によれば、メタル配線43に印可された静電気を、フレキシブル基板42を介さずに接地させることができる。メタル配線43に印可された静電気は、開口部OP1に挿入され、突出部43pと、インサートSUS板金32とを電気的に接続する導通部材31を介して、インサートSUS板金32に放電され、接地電位GNDにおいて接地される。これにより、フレキシブル基板42の断線を防ぐことができる。
According to the above configuration, the static electricity applied to the metal wiring 43 can be grounded without using the flexible substrate 42. The static electricity applied to the metal wiring 43 is inserted into the opening OP1 and discharged to the insert SUS sheet metal 32 via the conductive member 31 that electrically connects the protruding part 43p and the insert SUS sheet metal 32 to the ground potential. Grounded at GND. Thereby, disconnection of the flexible substrate 42 can be prevented.
また、図1に示す両面テープ33が防水テープであり、意匠板1の外側の全周囲を囲む構成であったとする。この構成によれば、図1に示す両面テープ33の内側(紙面右側)は、両面テープ33により閉領域が形成される。閉領域は、両面テープ33により外部からの水の浸入が防がれる防水保護範囲となる。また、両面テープ33は、防水性を有するため所定の幅を有しているものとする。
Further, it is assumed that the double-sided tape 33 shown in FIG. 1 is a waterproof tape and surrounds the entire outer periphery of the design board 1. According to this configuration, a closed region is formed by the double-sided tape 33 inside the double-sided tape 33 shown in FIG. The closed region is a waterproof protection range in which water entry from the outside is prevented by the double-sided tape 33. The double-sided tape 33 has a predetermined width because it has waterproofness.
よって、図1に示すように、防水性を有する両面テープ33の防水保護範囲内に開口部OP1を設ければ、突出部43p等が配置されている箇所に外部から水が浸入することを防ぐことができ防水性を保つことができる。
Therefore, as shown in FIG. 1, if the opening OP1 is provided within the waterproof protection range of the waterproof double-sided tape 33, water can be prevented from entering from the outside to the place where the protrusion 43p and the like are disposed. Can be waterproof.
また、図12に示したようなインサートSUS板金132を露出させるような加工を筐体34等に施さなくても済む。よって、図12に示したような構成と比べれば、加工が容易となるため、製造ばらつきを抑えることができる。
Further, it is not necessary to perform a process for exposing the insert SUS sheet metal 132 as shown in FIG. Therefore, as compared with the configuration as shown in FIG. 12, processing becomes easier, and manufacturing variations can be suppressed.
なお、以上では、開口部を意匠板1の背面に設けたが、開口部を前面に設ける構成とし、意匠板1の前面において接地部を設けて、突出部43pと接地する構成とすることも可能である。
In addition, although the opening part was provided in the back surface of the design board 1 in the above, it is set as the structure which provides an opening part in the front surface, and provides the grounding part in the front surface of the design board 1, and makes it the structure which contacts the protrusion part 43p. Is possible.
さらにいえば、上記構成は、意匠板、タッチパネルモジュール、液晶表示モジュール、これら以外の電子部品等を含むセットを、単に部品としてとらえ、それぞれ個別に設計すると得ることが困難である。すなわち、これらを個別に設計するだけでは、意匠板が有するメタル配線の突出部と、セット側のインサートSUS板金32とを導通部材31で接続するという発想が得難いといえる。
Furthermore, it is difficult to obtain the above configuration by simply considering a set including a design plate, a touch panel module, a liquid crystal display module, and other electronic components as components and designing them individually. That is, it can be said that it is difficult to obtain the idea of connecting the protruding portion of the metal wiring included in the design plate and the set-side insert SUS sheet metal 32 with the conductive member 31 only by designing them individually.
よって、上記構成は、意匠板、タッチパネルモジュール、液晶表示モジュール、これら以外の電子部品等を含むセットの位置関係を把握して、総合的に設計することにより得ることができるといえる。
Therefore, it can be said that the above-described configuration can be obtained by grasping the positional relationship of a set including a design board, a touch panel module, a liquid crystal display module, and other electronic components, and comprehensively designing it.
通信モジュールは、通常、タッチパネルのセンサーパターンからの影響をさけるため、タッチパネルから離間して、セット側において、電子機器の背面よりに配置されることが多い。
In order to avoid the influence from the sensor pattern of the touch panel, the communication module is usually arranged away from the touch panel and on the set side from the back of the electronic device.
よって、図1~3等に示すように、メタル配線43をタッチパネルのセンサーパターンと接続されるメタル配線41と個別に構成する場合であっても、図4および図5に示すように、メタル配線43をタッチパネルのセンサーパターンと接続されるメタル配線41と共通化する場合でも、通信モジュールに対する影響は、殆ど無い、あるいは少ないといえる。
Therefore, as shown in FIGS. 1 to 3, etc., even if the metal wiring 43 is configured separately from the metal wiring 41 connected to the sensor pattern of the touch panel, as shown in FIGS. Even when 43 is shared with the metal wiring 41 connected to the sensor pattern of the touch panel, it can be said that the communication module has little or no influence.
