Description
本發明,係有關於將檢測出觸碰位置之感測器電極藉由細線之網格來構成的觸控面板。The present invention relates to a touch panel configured by a grid of thin lines for sensor electrodes that detect a touch position.
圖1以及圖2A、2B,係為作為此種觸控面板之先前技術例,而對於在日本專利申請公開2017-103317號公報(2017年6月8日發行)中所記載之靜電電容式之觸控面板的構成作展示者。此觸控面板,係被設為在透明基板10上,依序層積形成第1導體層、絕緣層、第2導體層以及保護膜之構成。在圖1中,以矩形框所包圍的部份,係為感測器電極所位置之感測器區域20,在圖1中,係將感測器電極之詳細圖示作省略。FIGS. 1 and 2A and 2B are examples of the prior art of such a touch panel, and for the electrostatic capacitance type described in Japanese Patent Application Publication No. 2017-103317 (issued on June 8, 2017) The composition of the touch panel serves as a presenter. This touch panel is configured such that a first conductor layer, an insulating layer, a second conductor layer, and a protective film are sequentially stacked on the
感測器電極,係由第1感測器電極和第2感測器電極所成,第1感測器電極係藉由第1導體層而被形成,第2感測器電極係藉由第2導體層而被形成。The sensor electrode is formed by the first sensor electrode and the second sensor electrode, the first sensor electrode is formed by the first conductor layer, and the second sensor electrode is formed by the 2 conductor layers.
第1感測器電極30,係如同圖2A中所示一般,將使被配列在與感測器區域20之長邊21相平行的X方向上之複數之島狀電極31藉由連結部32而被作連結所成的電極列33,在與感測器區域20之短邊22相平行之Y方向上作複數並排配置,而構成之。The
第2感測器電極40,係如同圖2B中所示一般,將使被配列在Y方向上之複數之島狀電極41藉由連結部42而被作連結所成的電極列43,在X方向上作複數並排配置,而構成之。The
此些之第1感測器電極30以及第2感測器電極40,係分別藉由細線之網格而被形成,電極列33和43,係以相互被作了絕緣的狀態而相交叉,連結部32和42係位置在相互重疊之位置處。The
從第1感測器電極30之各電極列33的X方向兩端,係分別被導出有第2導出配線51,從第2感測器電極40之各電極列43的Y方向其中一端,係分別被導出有第1導出配線52。被作複數配列並從感測器區域20所被導出之第1導出配線52以及第2導出配線51,在圖1中,係將除了位置在配列之兩端處者以外的圖示作省略。From both ends of each
在成為矩形狀的透明基板10之其中一方之長邊的中央部分處,係被配列形成有端子部53,第1導出配線52以及第2導出配線51係分別一直延伸至端子部53處並與端子部53作連接。以包圍感測器區域20、第1導出配線52以及第2導出配線51的方式而被形成於透明基板10之周緣部處的接地配線54,亦係被與端子部53作連接。At the central portion of one of the long sides of the rectangular
第1導出配線52、第2導出配線51以及端子部53,係藉由第1導體層而被形成,接地配線54,係被形成於第1以及第2導體層之雙方處。The first lead-
具備有上述一般之構成的第1以及第2導體層,在此例中係成為使用包含有銀等之導電粒子的導電墨水,並藉由凹版膠印(gravure offset)印刷而被作印刷形成者。The first and second conductor layers having the above-mentioned general configuration are used in this example as conductive ink using conductive particles containing silver or the like, and are printed by gravure offset printing.
另外,在觸控面板中,當將電極圖案或配線圖案使用包含有銀等之導電粒子之導電墨水來進行印刷形成的情況時,為了不會對於觸控面板所被作配置之顯示部的視覺辨認性有所損害,將位置在感測器區域中之感測器電極設為具備有高的光透過效率並且難以被視覺辨認到一事係為重要,因此,如同上述之觸控面板一般地,使用導電墨水而印刷形成的感測器電極,一般而言係成為藉由細線之網格所構成者。In addition, in the touch panel, when the electrode pattern or the wiring pattern is printed and formed using conductive ink containing conductive particles such as silver, in order not to visualize the display portion where the touch panel is arranged Recognition is impaired. It is important to set the sensor electrode located in the sensor area to have high light transmission efficiency and difficult to be visually recognized. Therefore, like the above-mentioned touch panel, Sensor electrodes printed using conductive ink are generally made up of a grid of thin lines.
另一方面,就算是如此這般地藉由細線之網格來構成感測器電極,也無法避免起因於細線之網格有所存在的部分和並未存在的部分所產生的視覺性的對比之發生,此種對比,係成為對於顯示部之視覺辨認性造成有一定程度的影響。On the other hand, even if the sensor electrode is formed by a grid of thin lines in this way, the visual contrast between the existing part and the non-existing part of the thin line grid cannot be avoided. As a result, this contrast has a certain impact on the visibility of the display.
關於此點,在上述之觸控面板中,由於第1感測器電極30和第2感測器電極40係使連結部32和42位置在相互重疊之位置處並以使電極列33和43相互交叉的方式而被作配置,亦即是,第2導體層之島狀電極41,係成為於第1導體層中之並未存在有細線之網格的位置處,以將該位置作填埋的方式而被作配置的構成,因此,在第1導體層處所發生的對比和在第2導體層處所發生的對比,係以相互抵消的方式而作用,藉由此,感測器區域之對比度係成為被作降低。In this regard, in the above-mentioned touch panel, since the
然而,在第1導體層和第2導體層之間,由於係存在有絕緣層,因此,第2導體層之視覺性的對比、和中介有絕緣層之第1導體層之視覺性的對比,係並非為相同,關於此點,在先前技術之觸控面板中,係成為並未對於感測器區域之對比度完全消除的狀態。However, between the first conductor layer and the second conductor layer, since there is an insulating layer, the visual contrast between the second conductor layer and the first conductor layer with the insulating layer in between, This is not the same. In this regard, in the touch panel of the prior art, the contrast of the sensor area is not completely eliminated.

另一方面,圖4,係為對於第2層64之印刷配線的詳細內容作展示者,在感測器區域20處,係被形成有第2感測器電極100和第2假配線110。第2感測器電極100,係將使被配列在Y方向上之複數之島狀電極101藉由連結部102而被作連結所成的電極列103,在X方向上作複數並排配置,而構成之,第2假配線110,係在感測器區域20中,於第2感測器電極100所被作設置之區域以外的區域處,與第2感測器電極100相互絕緣地而被作設置。On the other hand, FIG. 4 shows the details of the printed wiring of the
第2感測器電極100和第2假配線110,均係藉由細線之網格所構成,此些之第2感測器電極100和第2假配線110,係於該些之間被形成有第2空隙121地而被作配置,並且構成身為單一之連續的周期性網格圖案之第2網格圖案120。被包含於第2網格圖案120中之細線,係在與第2空隙121相交叉之場所處被作斷絕。第2網格圖案120,在此例中,係被設為與第1網格圖案90相同之網格圖案,構成網格的細線之與感測器區域20之長邊21之間所成的角度,亦係被設為相同。另外,與圖3相同的,係將第2空隙121相對性地作擴大展示。Both the
圖5,係為對於將圖3中所示之第1層62之印刷配線和圖4中所示之第2層64之印刷配線包夾著絕緣層63地而作了重疊的狀態作展示者,第1層62之第1網格圖案90和第2層64之第2網格圖案120,係以相互在將單位格子之菱形之邊各200μm地作對分的中點處而相互交叉的方式而被作重疊,藉由此,係成為使一邊之長度為200μm的菱形之格子如同圖5中所示一般地在感測器區域20之全面上極為均勻地被形成的狀態。另外,第1感測器電極70之電極列73和第2感測器電極100之電極列103,係使連結部72和102位置在相互重疊之位置處而相互交叉。FIG. 5 is a diagram showing a state where the printed wiring of the
如同上述一般,若依據本例,則在第1感測器電極70所被形成之第1層62的感測器區域20處,第1網格圖案90係成為均一地存在的狀態,在第2感測器電極100所被形成之第2層64的感測器區域20處,第2網格圖案120係成為均一地存在的狀態。故而,在第1層62以及第2層64之兩者中,係均不會發生起因於細線之網格之有無所導致的視覺性之對比,就算是在使第1層62和第2層64作了重疊的狀態下,亦當然並不會發生視覺性的對比,而成為能夠將感測器區域20之對比度完全地消除者。故而,係並不會對於顯示部造成視覺性的影響,而能夠得到在美觀性上係為佳之優良品質的觸控面板。As described above, according to this example, at the
另外,第1網格圖案90和第2網格圖案120,由於係如同上述一般地以在將菱形之邊各200μm地作對分的中點處而交叉的方式而被作重疊,因此,構成第1網格圖案90之細線和構成第2網格圖案120之細線係並不會相互接近,故而,也不會發生像是相互作了接近的細線之組看起來像是一條的粗線一般之描繪出可視覺辨認到的相對性而言為明顯之線的情形。In addition, the
第1層62之印刷配線和第2層64之印刷配線,在上述之例中,係成為在基體61之其中一面側處包夾著絕緣層63地而被形成者,但是,第1層62之印刷配線和第2層64之印刷配線,係亦可設為分別被形成在基體61之其中一面側和另外一面側處的構成。圖6B,係為對於此構成作展示者,針對與圖6A相對應之部分,係附加有相同之元件符號。圖6B中,67係代表保護膜。另外,基體61係被設為絕緣體。In the above example, the printed wiring of the
於此,針對被形成在第1感測器電極70所被作設置之第1層62處的第1網格圖案以及被形成在第2感測器電極100所被作設置之第2層64處的第2網格圖案,更進而作詳細說明。Here, for the first grid pattern formed on the
第1網格圖案和第2網格圖案,係均被設為將1種類的單位格子作為配列要素而藉由依循於一對之配列周期方向的平面填充所得到的格子圖案,一對之配列周期方向,係相互為非平行,在一對之配列周期方向之各者所定義之方向上,係產生有單位格子之與該配列周期方向相對應的並進周期,第1網格圖案和第2網格圖案,係將一對之配列周期方向和與該些分別相互對應的並進周期相互設為相等。Both the first grid pattern and the second grid pattern are set as a grid pattern obtained by filling a plane in the direction of a pair of alignment cycles with one type of unit grid as the alignment element. The periodic direction is non-parallel to each other. In the direction defined by each of the paired arranging periodic directions, a parallel period corresponding to the arranging periodic direction of the unit lattice is generated, the first grid pattern and the second In the grid pattern, the direction of the paired arrangement period and the parallel periods corresponding to these are equal to each other.
第1網格圖案和第2網格圖案,係以具備有特定之偏差的方式而被作對位並重疊。在上述之例中,第1網格圖案和第2網格圖案之單位格子,係以在將被設為一邊之長度為400μm之菱形的菱形之邊各200μm地作對分的中點處而交叉的方式,來使第1網格圖案和第2網格圖案被作重疊,亦即是,第1網格圖案和第2網格圖案,係以在一對之配列周期方向的雙方之各者中具備有與該配列周期方向相對應的並進周期之1/2周期之偏差的方式而被作對位並重疊。藉由此,來成為使構成第1網格圖案和第2網格圖案之細線彼此以最大的間隔來相互分離,並且成為在被作了重疊的狀態下一邊之長度為200μm的菱形會被均一地形成,但是,在第1網格圖案和第2網格圖案之重疊中,係只要以在一對之配列周期方向的雙方之各者中具備有與該配列周期方向相對應的並進周期之1/4周期以上3/4周期以下之範圍之偏差的方式來作對位即可,藉由此,係能夠充分地避免由重疊所導致的細線彼此之接近。The first grid pattern and the second grid pattern are aligned and overlapped with a specific deviation. In the above example, the unit grids of the first grid pattern and the second grid pattern intersect at the midpoint of the rhombus that is set to a side with a length of 400 μm, each of which is divided by 200 μm. The first grid pattern and the second grid pattern are overlapped, that is, the first grid pattern and the second grid pattern are arranged in a pair of the two in the periodic direction It is aligned and overlapped in such a way that a deviation of 1/2 of the parallel period corresponding to the direction of the arrangement period is provided. By this, the thin lines constituting the first grid pattern and the second grid pattern are separated from each other at the maximum interval, and in the overlapped state, the rhombus with a length of 200 μm on one side is uniformized However, in the overlapping of the first grid pattern and the second grid pattern, it is only necessary to have a parallel period corresponding to the arrangement period direction in each of the pair of arrangement period directions in a pair The alignment may be performed in a manner of deviation within the range of 1/4 cycle to 3/4 cycle, and by this, it is possible to sufficiently avoid the proximity of the thin lines caused by overlap.
單位格子,在上述之例中,係被設為菱形,但是,係並不被限定於此,而可採用多樣化的形狀。例如,單位格子之形狀,係亦可為正方形或正六角形。此些之格子圖案之一對之配列周期方向之相對角度,在正方形中係成為90°,在正六角形中係成為60°。又,並進周期,係成為相互平行之相對向之邊的彼此之間隔(在正方形時,係為1邊之長度)。The unit grid is set to a rhombus in the above example, but the system is not limited to this, and various shapes can be adopted. For example, the shape of the unit grid may be square or regular hexagon. The relative angle of the arrangement period direction of one pair of these lattice patterns becomes 90° in squares and 60° in regular hexagons. In addition, the advancing period is the interval between the mutually opposing sides that are parallel to each other (in the case of a square, the length is one side).
圖7A、7B,係分別為對於正方形之格子圖案131、132作展示者,圖7C,係為對於該些之格子圖案131、132為以在一對之配列周期方向之雙方的各者中具備有與該配列周期方向相對應的並進周期之1/2周期之偏差的方式而被作對位並重疊的狀態作展示者。FIGS. 7A and 7B show the
圖8A、8B,係分別為對於正六角形之格子圖案141、142作展示者,圖8C,係為對於該些之格子圖案141、142為以在一對之配列周期方向之雙方的各者中具備有與該配列周期方向相對應的並進周期之1/2周期之偏差的方式而被作對位並重疊的狀態作展示者。FIGS. 8A and 8B show the regular
進而,單位格子之形狀,係亦可為長方形或平行四邊形,又,亦可為被3組之相互平行之相對向之邊所包圍的相對向之2邊間之間隔並非為相同之六角形。Furthermore, the shape of the unit grid may be a rectangle or a parallelogram, or the interval between two opposing sides surrounded by three sets of opposing sides that are parallel to each other may not be the same hexagon.
圖9,係為對於單位格子為長方形之格子圖案151、152被作了重疊的狀態作展示者,圖10,係為對於具備有被3組之相互平行之相對向之邊所包圍的相對向之2邊間之間隔之其中一者為窄的橫方向為長之六角形之單位格子的格子圖案161、162被作了重疊的狀態作展示者。Fig. 9 is a display for the state in which the
在此些之圖9以及圖10中所例示一般之多樣化的形狀之單位格子,係可藉由對於正方形或正六角形之單位格子或者是藉由該單位格子所成的格子圖案而進行下述(1)或(2)之圖形轉換操作,來得到之。The general unit cell of various shapes illustrated in FIG. 9 and FIG. 10 can be performed by a square or regular hexagonal unit cell or a lattice pattern formed by the unit cell as follows (1) or (2) graphics conversion operation to get it.
(1)使平面內之任意之一個方向作向異性伸縮的圖形轉換 (2)轉換為「將平面內之任意所定義的第1斜交座標系中之圖形的各點之座標值,代入至具備有與第1斜交座標系相異之座標軸間角度的任意之第2斜交座標系中,所得到的圖形」之圖形轉換(1) Convert the graphic in any direction in the plane to anisotropic expansion and contraction (2) Convert to "the coordinate value of each point of the graphic in the first oblique coordinate system defined in the plane, substitute into Graphic conversion of any second oblique coordinate system with an angle between coordinate axes different from the first oblique coordinate system"
例如,藉由(1)之操作,正方形係成為長方形或菱形、平行四邊形,藉由(2)之操作,正方形係成為菱形。又,正六角形,係藉由(1)或(2)之操作,而成為被3組之相互平行之相對向之邊所包圍的相對向之2邊間之間隔並非為相同之六角形。For example, by the operation of (1), the square becomes a rectangle or a rhombus, a parallelogram, and by the operation of (2), the square becomes a rhombus. In addition, the regular hexagon is formed by the operation of (1) or (2), and the interval between the opposing two sides surrounded by the three opposing sides that are parallel to each other is not the same hexagon.
另外,單位格子,在上述記載中,雖係成為將4個或6個的頂點藉由以直線所成之邊來作連結並將內部作了包圍的形狀,但是,係亦可設為將4個或6個的頂點藉由曲線或以直線和曲線所成之邊來作連結並將內部作了包圍的形狀。In addition, in the above description, the unit grid has a shape in which four or six vertices are connected by edges formed by straight lines and surrounds the interior. However, the unit grid can also be set to 4 One or six vertices are connected by a curve or an edge formed by a straight line and a curve, and the interior is surrounded by a shape.
此種形狀之單位格子,係可藉由對於正方形或正六角形之單位格子而進行下述(3)之操作,來得到之。The unit cell of this shape can be obtained by performing the following operation (3) for the unit cell of square or regular hexagon.
(3)將相互平行之相對向之邊的線段,一同置換為相同之曲線或者是以曲線和直線之結合所成之線(3) Replace the line segments of opposite sides parallel to each other with the same curve or a line formed by the combination of curve and straight line
圖11,係為對於使具備有對正方形之單位格子而進行了(3)的操作之單位格子的格子圖案171、172被作了重疊的狀態作展示者,圖12,亦係為對於使具備有對正方形之單位格子而進行了(3)的操作之單位格子的格子圖案181、182被作了重疊的狀態作展示者。另外,圖13A,係為對於對正方形之單位格子而進行了(3)的操作所得到之單位格子190的形狀例更進而作展示者,圖13B,係為對於對正六角形之單位格子而進行了前述(1)的操作所得到之單位格子200的形狀例更進而展示者。FIG. 11 is a display for the state in which the
能夠將1種類的單位格子依循相互非平行之一對之配列周期方向以及與該些分別相互對性之並進周期而並行前進的操作來進行平面填充之單位格子或者是以該單位格子所成之格子圖案,係亦可將上述(1)~(3)之操作作複合性的進行,來得到之。Unit grids that can be plane-filled according to the arrangement period direction of a pair of unit grids that are not parallel to each other and the parallel cycles of these mutually opposite parallel cycles, or a unit grid formed by the unit grid The lattice pattern can also be obtained by performing the above operations (1) to (3) in a complex manner.
另外,第1網格圖案和第2網格圖案,只要單位格子之配列周期方向與並進周期係相互一致,則單位格子的形狀自身係並非絕對需要相互一致。例如,第2網格圖案之單位格子,係亦可為對於第1網格圖案之單位格子而進行了上述(3)之操作者。In addition, as long as the arrangement period direction of the unit grid and the parallel period system coincide with each other in the first grid pattern and the second grid pattern, the shape itself of the unit grid does not necessarily need to coincide with each other. For example, the unit grid of the second grid pattern may be the operator who performed the above (3) for the unit grid of the first grid pattern.
以上,雖係針對被形成於第1層62處之第1網格圖案以及被形成於第2層64處之第2網格圖案而作了說明,但是,此些之第1網格圖案以及第2網格圖案,係如同前述一般地,為了將感測器區域20之對比消除,而分別位置在感測器區域20之全部區域處,在圖6A中所示之層構成之觸控面板的情況時,第1感測器電極70和第2假配線110係包夾著絕緣層63而相互重疊,同樣的,第2感測器電極100和第1假配線80係成為包夾著絕緣層63而相互重疊。In the above, the first grid pattern formed at the
接著,針對藉由第2層64所形成之第2感測器電極100、和在感測器區域20之周圍的邊框區域處而藉由第1層62所形成的第1導出配線52,此兩者間之連接部分作說明。Next, for the
圖14,係為對於此連接部分作展示者,在第1導出配線52之前端處,係被形成有由細線之細密之網格所成的第1連接部52a。另一方面,在第2感測器電極100之端緣處,係被延長形成有延長部104。延長部104,在此例中,係由使構成第2感測器電極100之網格作了延長的大網格部104a、和從大網格部104a起而更進而作了延長形成的小網格部104b,而構成之。小網格部104b,係被設為細線之細密的網格,此小網格部104b和第1導出配線52之第1連接部52a,係成為具備有單位格子為正方形之同一之網格構造者。FIG. 14 is a display of this connection portion. At the front end of the first lead-
在絕緣層63處,係被形成有第1貫通孔63a,第1導出配線52之第1連接部52a和第2感測器電極100之延長部104,係位置於此第1貫通孔63a中,並相互被作接觸導通,藉由此,第1導出配線52係被與第2感測器電極100作連接。另外,具備有同一之網格構造的第1連接部52a和小網格部104b,在此例中,係如同圖14中所示一般,以具備有1/2節距(1/2周期)之偏差的方式而被作對位並重疊。At the insulating
另一方面,在與第2感測器電極100包夾著絕緣層63地而相互重疊之第1假配線80(在圖14中係以虛線作標示)的邊緣處,在此例中,係被設置有使細線之網格作了缺損的第1凹部81,藉由此第1凹部81,第1假配線80之邊緣係從第1貫通孔63a而分離。藉由設置此種第1凹部81,在此例中,係成為能夠避免起因於第1假配線80與第2感測器電極100相接觸一事所發生的問題者。On the other hand, at the edge of the first dummy wiring 80 (indicated by a broken line in FIG. 14) overlapping the
亦即是,若是起因於在第1層62、絕緣層63以及第2層64之印刷中所發生的印刷偏差或暈滲而導致第1假配線80從絕緣層63之邊緣而超出、亦即是超出至第1貫通孔63a內,並與第2感測器電極100之延長部104作接觸導通,則會發生該第1假配線80所作了接觸導通的第2感測器電極100之靜電電容產生顯著的變化之問題。相對於此,藉由在第1假配線80處,設置使其之邊緣從第1貫通孔63a而分離的第1凹部81,由於係被形成有確保有該第1凹部81之尺寸之量的絕緣之間隙,因此,就算是在印刷中發生有該尺寸以內之的印刷偏差或暈滲,也能夠避免第1假配線80與第2感測器電極100之接觸導通,故而,係能夠防止第2感測器電極100之靜電電容產生變化之問題的發生。另外,在圖14中所示之第1凹部81的尺寸d1
、d2
,例如係設為確保有160μm之程度者。That is, if the printing error or blooming occurs in the printing of the
圖15,係為對於第1感測器電極70和第2導出配線51之連接部分作展示者。在第2導出配線51之前端處,係與第1導出配線52之第1連接部52a相同的,被形成有由細線之細密之網格所成的第2連接部51a,經由此第2連接部51a,第1感測器電極70和第2導出配線51係被作連接。FIG. 15 shows a connection part between the
第1感測器電極70、第2導出配線51以及第2連接部51a,係藉由相同之第1層62而被形成,故而,第2連接部51a係成為被絕緣層63所覆蓋,但是,例如在將被與第1感測器電極70之端緣作連結的第2連接部51a作為用以進行第1感測器電極70之電性檢查之檢查用墊片來使用的情況時,係如同圖15中所示一般,在絕緣層63處,係被設置有使第2連接部51a露出之第2貫通孔63b。於此情況,係可能會發生與前述之第2感測器電極100和第1導出配線52之間之連接部分相同的問題。故而,在與第1感測器電極70包夾著絕緣層63地而相互重疊之第2假配線110(在圖15中係以虛線作標示)的邊緣處,係設置使第2假配線110之邊緣從第2貫通孔63b而分離之第2凹部111。The
藉由如此這般地設置第2凹部111,係能夠防止起因於印刷偏差或暈滲而導致第2假配線110超出至第2貫通孔63b內並與第2連接部51a作接觸導通並且造成第1感測器電極70之靜電電容產生變化之問題的發生。另外,在圖15中所示之第2凹部111的尺寸d1
、d2
,係設為與第1凹部81相同之值。By providing the second concave portion 111 in this way, it is possible to prevent the second dummy wiring 110 from exceeding the second through
另外,如同上述一般,當在第1假配線80或第2假配線110之邊緣處(換言之,第1網格圖案或第2網格圖案之邊緣處)存在有並不存在著細線之網格之凹部的情況時,凹部係以位置在感測器區域之外側處為理想,亦即是,感測器區域之邊緣係以設定在較凹部而更內側處為理想。In addition, as described above, when there is a grid where no thin line exists at the edge of the
