Description
本案係關於一種平面顯示裝置的技術，尤指一種觸控螢幕面板及其製作方法。The present invention relates to a technology of a flat display device, and more particularly to a touch screen panel and a method for fabricating the same.
通常，觸控螢幕裝置係指一種裝置，當一使用者之一手指或是一物體，例如一觸控筆，接觸該螢幕所顯示之一特定位置時，該觸控螢幕對於該接觸點識別一座標值，以執行配備於該觸控螢幕之一電子裝置的一控制。依照驅動和感應的方法，以及應用於該觸控螢幕裝置的技術，該觸控螢幕裝置可以有不同類型的螢幕，例如一電容式觸控螢幕、電阻式薄膜觸控螢幕、使用紅外線或超音波的表面音波式觸控螢幕、或其類似者。
習知技術上，該觸控螢幕面板係以將該第一感應電極圖型與該第二感應電極圖型形成於相同平面上的方式製作，且該第二感應電極圖型(或該第一感應電極圖型)係經由與該第一及第二感應電極圖型形成於不同平面上的橋接圖型相連接，使得該第一感應電極圖型及該第二感應電極圖型互相不接觸。
亦即，請參閱第1圖所示，於一習知觸控螢幕面板中，第一感應電極圖型20-1及第二感應電極圖型20-2係在一透明基板(圖中未顯示)上規則地以菱形排列方式互相相鄰而形成，於此，該第一感應電極圖型20-1係於該透明基板(未顯示)上形成複數個列，且排列於相同列之該第一感應電極圖型20-1係互相連接而形成。另一方面，該第二感應電極圖型20-2係於該透明基板(未顯示)上形成複數個列，且排列於相同列之該第二感應電極圖型20-2係互相分離而形成，此時，該橋接圖型係用來將該分離的第二感應電極圖型20-2互相連接。
第2圖說明於第1圖所示之習知觸控螢幕中被該橋接圖型所相連接的該第二感應電極圖型，其中第2A圖係為一底視圖，而第2B圖係從第2A圖線A-A’方向所取的一截面視圖。
於此，參考第2圖，製作該習知觸控螢幕面板的方法將說明如下。首先，第一感應電極圖型20-1及第二感應電極圖型20-2係形成於一透明基板10上，此時，排列於相同列之該第一感應電極圖型20-1係形成為互相連接，而排列於相同列之該第二感應電極圖型20-1係形成為互相分離；其次，一絕緣層30係配置於該透明基板10上以覆蓋該第一感應電極圖型20-1及該第二感應電極圖型20-2；然後，接觸孔40於該第二感應電極圖型20-2上之該絕緣層30中形成；之後，該接觸孔40以導電物質填入；接著，橋接圖型50形成於該絕緣層30上，以將該分離的第二感應電極圖型20-2互相連接。
在該習知觸控螢幕面板中，該接觸孔40及該橋接圖型50係需要用來連接分離的該第二感應電極圖型20-2，關於這方面，由於該接觸孔40之面積小而具有一高接觸電阻，因此該第二感應電極圖型20-2間的導電性降低，且因此應用於具有一大面積的一觸控螢幕面板會有難度；此外，由於形成該接觸孔40的光刻製程係額外進行，使得該觸控螢幕面板的整體製造程序變得更為複雜。更進一步，因為該第一感應電極圖型20-1與該第二感應電極圖型20-2係排列於相同平面，在該第一感應電極圖型20-1與該第二感應電極圖型20-2之間必須維持一預定距離或更大的一間隙，因此，在該觸控螢幕面板之製造程序中，例如於該第一感應電極圖型20-1與該第二感應電極圖型20-2之間的短路等缺陷，可能會發生。Generally, a touch screen device refers to a device that recognizes a contact point of a touch screen when a user's finger or an object, such as a stylus, touches a specific position displayed on the screen. A coordinate value to perform a control of an electronic device equipped with one of the touch screens. According to the driving and sensing method and the technology applied to the touch screen device, the touch screen device can have different types of screens, such as a capacitive touch screen, a resistive film touch screen, using infrared or ultrasonic waves. Surface acoustic wave touch screen, or the like.
Conventionally, the touch screen panel is formed by forming the first sensing electrode pattern and the second sensing electrode pattern on the same plane, and the second sensing electrode pattern (or the first The sensing electrode pattern is connected to the bridge pattern formed on the different planes by the first and second sensing electrode patterns, such that the first sensing electrode pattern and the second sensing electrode pattern do not contact each other.
That is, as shown in FIG. 1 , in a conventional touch screen panel, the first sensing electrode pattern 20-1 and the second sensing electrode pattern 20-2 are on a transparent substrate (not shown in the figure). The first sensing electrode pattern 20-1 is formed on the transparent substrate (not shown) to form a plurality of columns, and is arranged in the same column. A sensing electrode pattern 20-1 is formed by interconnecting. On the other hand, the second sensing electrode pattern 20-2 is formed on the transparent substrate (not shown) to form a plurality of columns, and the second sensing electrode patterns 20-2 arranged in the same column are separated from each other to form At this time, the bridge pattern is used to interconnect the separated second sensing electrode patterns 20-2.
FIG. 2 illustrates the second sensing electrode pattern connected to the bridge pattern in the conventional touch screen shown in FIG. 1 , wherein FIG. 2A is a bottom view, and FIG. 2B is a bottom view. A cross-sectional view taken in the direction of line AA' of the 2A line.
Here, referring to FIG. 2, a method of fabricating the conventional touch screen panel will be described below. First, the first sensing electrode pattern 20-1 and the second sensing electrode pattern 20-2 are formed on a transparent substrate 10. At this time, the first sensing electrode pattern 20-1 arranged in the same column is formed. The second sensing electrode patterns 20-1 arranged in the same column are formed to be separated from each other. Secondly, an insulating layer 30 is disposed on the transparent substrate 10 to cover the first sensing electrode pattern 20 -1 and the second sensing electrode pattern 20-2; then, the contact hole 40 is formed in the insulating layer 30 on the second sensing electrode pattern 20-2; after that, the contact hole 40 is filled with a conductive material Next, a bridge pattern 50 is formed on the insulating layer 30 to interconnect the separated second sensing electrode patterns 20-2.
In the conventional touch screen panel, the contact hole 40 and the bridge pattern 50 are required to connect the separated second sensing electrode pattern 20-2. In this regard, the contact hole 40 has a small area. And having a high contact resistance, so the conductivity between the second sensing electrode pattern 20-2 is reduced, and thus it is difficult to apply to a touch panel having a large area; in addition, since the contact hole 40 is formed The lithography process is additionally performed, making the overall manufacturing process of the touch screen panel more complicated. Further, the first sensing electrode pattern 20-1 and the second sensing electrode pattern 20-2 are arranged in the same plane, and the first sensing electrode pattern 20-1 and the second sensing electrode pattern are A gap of a predetermined distance or more must be maintained between 20-2. Therefore, in the manufacturing process of the touch screen panel, for example, the first sensing electrode pattern 20-1 and the second sensing electrode pattern Defects such as short circuits between 20-2 may occur.

而且，依據本發明的觸控螢幕面板，有可能藉由在一預定距離或以下之間距形成該第一及第二感應圖型，以改善觸控靈敏性及可見性。In view of the above circumstances, it is an object of the present invention to provide a touch screen panel having improved conductivity of a sensing electrode pattern and a method of fabricating the same.

本發明揭露一種觸控螢幕面板及其製作方法，其包含一第一感應圖型，形成於一絕緣層之一下表面上；以及一第二感應圖型，形成於該絕緣層之一上表面上，其中：該第一感應圖型及該第二感應圖型係以互為不同之方向形成，且當該第一感應圖型及該第二感應圖型投影至相同平面時，該第一感應圖型及該第二感應圖型具有4μm或以下之一間隙形成於其間，藉此可改善導電性、觸控靈敏性及可見性。
如下所述，本發明之一種觸控螢幕面板及其製作方法，將參閱後附圖式加以詳細說明。
在本發明之敘述中，判斷足以使本發明的主旨不必要模糊的已公開習知功能及配置的詳細敘述被省略。此外，於本說明書及申請專利範圍中所使用的術語或用詞不應被詮釋為侷限於某個詞彙意義，並且應以發明人所瞭解適當的概念，基於他或她能夠定義的術語，以其他人所見最好的方式來描述他或她的發明。
然而，相同技術領域中具有通常知識者將理解，所提供之實施方式係作為說明之目的，並非限定於如實施方式及後附申請專利範圍所揭露欲保護的主題內容。因此，顯然對於相同技術領域中具有通常知識者而言，於不脫離本發明之範疇及精神下，可能將實施例作出各種改變及修正，且都適當地包含於後附申請專利範圍所定義的範圍。
第3圖為依據本發明之一實施方式，說明一種觸控螢幕面板之一截面視圖。
請參閱第3圖，依據本發明之一實施方式之一觸控螢幕面板100，包含一基底構件102、形成於該基底構件102上之第一感應圖型104和一絕緣層106，以及形成於該絕緣層106上之第二感應圖型108。
該基底構件102可使用一透明基板(或是一膜)。例如，該基底構件102可使用，但不限於，一玻璃基板或一塑膠基板。此外，該基底構件102可由相關技術領域中習知的任何可撓性(flexible)材料所形成。
該第一感應圖型104係於該基底構件102上所形成，於此，該第一感應圖型104係於該基底構件102上以複數個列形成，且排列於同一列之該第一感應圖型104係互相連接而形成，該第一感應圖型104可以多邊形形狀所形成。多邊形形狀的一實施例，可以為三角形、四邊形(菱形、四邊形或正方形)、六邊形、或其類似者，然而，該第一感應圖型104之形狀不限於此，且該第一感應圖型104之形狀可由其他不同形狀所形成。該第一感應圖型104可由導電材料，例如氧化銦錫(ITO)、金屬奈米線(metal nanowire)、金屬網(metal mesh)、石墨烯(graphene)、有機電極、或其類似者所製成，且可由透明電極所製成。於本發明中，該透明電極係指不可被視覺識別的電極，因此該透明電極可包含即使材料本身並非透明、但由於其微細結構而不可被視覺識別的電極。
如第3圖所示，該第一感應圖型104可被該絕緣層埋入其內而未自該絕緣層之該表面凸出而形成，然不限於此。如有必要，該第一感應圖型104可以自該絕緣層之該表面凸出而形成。
該絕緣層106係形成於該基底構件102上以覆蓋該第一感應圖型104。該絕緣層106扮演使該第一感應圖型104電絕緣於該第二感應圖型108、同時保護該基底構件102之角色。該絕緣層106可由一無機材料或有機材料所製成，當該絕緣層106係由一無機材料所製成時，可藉由例如濺鍍一無機材料，如二氧化矽，使該絕緣層106沉積於該基底構件102上，當該絕緣層106係由一無機材料所製成時，該絕緣層106可以具有可維持在一預定水準内的一耐受性(durability)。同時，當該絕緣層106係由一有機材料所製成，可藉由施加一有機材料，例如一光硬化樹脂，並使之硬化，可使該絕緣層106於該基底構件102上形成，通常，該有機材料係在一相對低溫(例如，約220ºC)烘烤。因此，當一偏光片(polarizer)(圖中未顯示)形成於該基底構件102及該絕緣層106之間，可以避免所得的偏光片(未顯示)被該有機材料所破壞。更進一步，當該基底構件102係由一撓性材料所製成，該絕緣材料106係以有機材料所製成為較佳選擇。
該第二感應圖型108係形成於該絕緣層106上。此處，該第二感應圖型108係於該基底構件102上以複數個列形成，且排列於同一列之該第二感應圖型108係互相連接而形成，亦即，由於該第二感應圖型108係形成於與該第一感應圖型104所形成於其上之不同平面上，排列於該相同列之該各自第二感應圖型108可互相連接。
該第二感應圖型108係以與該第一感應圖型104所形成方向之不同方向(例如其正交方向)形成，因此，該第一感應圖型104及該第二感應圖型108可提供一使用者所接觸之點的X及Y軸座標上的資訊。
該第二感應圖型108亦可以多邊形形狀所形成。多邊形形狀的一實施例，可以為三角形、四邊形(菱形、四邊形或正方形)、六邊形、或其類似者，然而，該第二感應圖型108之形狀不限於此，且該第二感應圖型108之形狀可由其他不同形狀所形成。該二感應圖型108可由導電材料，例如氧化銦錫(ITO)、金屬奈米線、金屬網、石墨烯、有機電極、或其類似者所製成，且可由透明電極所製成。
於本發明中，當該第一感應圖型及該第二感應圖型投影至相同平面時，該第一感應圖型及該第二感應圖型係以之間具有4μm或以下之一間隙W所形成。
如第1圖及第2圖所示，在其中具有該第一感應圖型20-1及該第二感應圖型20-2形成於相同平面之結構的習知觸控螢幕面板中，該第一感應圖型20-1及該第二感應圖型20-2由於例如圖型間干涉之問題，而應互相分離。
然而，本發明之觸控螢幕面板，該第一感應圖型104及該第二感應圖型108係形成於互相不同之平面上，因此該第一和第二感測圖案104和108可以不考慮其間所形成之間隙而形成。
此外，本發明人構思的想法是，當該第一和第二感測圖案104和108被投影在同一平面上時，假如在它們之間所形成的間隙為4微米或以下，該第一感測圖案104與該第二感測圖案108之間產生的電容係明顯增加而提高觸控靈敏性，且此想法完成了本發明。
具體地，觸控靈敏性可由互電容(mutual capacitance，Cm)所表示，互電容係在接觸螢幕時，於該第一感測圖案104和該第二感測圖案108之間所產生，ΔCm代表在接觸螢幕前及後之Cm的變化量。
在接觸螢幕時，於該第一感測圖案104和該第二感測圖案108之間所產生的互電容係由以下方程式1所表示：

(其中，ε代表一介電常數，A代表一截面積，而d代表圖型間的一距離。)
當該第一感測圖案104和該第二感測圖案108係互相接近而形成時，d為減少，因而Cm為增加。
由於ΔCm代表在接觸螢幕前(基礎Cm)及在接觸螢幕後(接觸Cm)之Cm的變化量，假如ΔCm大，接觸螢幕前後的信號差值就大，亦即觸控靈敏性為優良。
此外，當基礎Cm增加，一信號雜訊比(signal-to-noise ratio，SNR)亦增加而改善觸控靈敏性，亦即，該觸控螢幕面板之SNR可以由Cm對Ccell
的比例來表示。Ccell
係指在晶胞(cell)電極(例如液晶顯示器(LCD)電極、有機發光二極體(OLED)電極或其類似者)中，而非指該第一及第二感應圖型104及108中，所產生的電容。Ccell
作用似一種雜訊，其在觸控螢幕面板中係無用的電容，關於此方面，當該第一感測圖案104和該第二感測圖案108間的間隙係形成為4μm或以下，相較於其數值落於上述範圍以外的例子，該基礎Cm係大幅增加且SNR亦增加而改善觸控靈敏度。
假如該第一及第二感應圖型104及108間的間隙係落於本發明上述範圍內，該間隙愈小，該基礎Cm增加愈多。因此，於本發明中，該間隙的下限值並不特別限定於維持這種趨勢的一範圍值內，例如，該間隙可為0(零)。
如本發明之另一實施方式，其中該間隙W具有一負值之例子(其中當該第一感應圖型及該第二感應圖型投影至相同平面時，這些圖案係有重疊)，亦包含於本發明之範圍內。關於此方面，第4圖示意說明該觸控螢幕面板之該第一感測圖案和該第二感測圖案間間隙的差別、以及第5圖依據本案發明另一實施方式，示意說明當該間隙具有一負值之一觸控螢幕面板。
當該第一感應圖型及該第二感應圖型係有重疊(當該間隙具有一負值)時，ΔCm以及Cm為大幅增加，因此該觸控靈敏性為大幅增加。
當該第一及第二感應圖型係有重疊，該重疊區域面積並無特別限定，然而，例如，以該第一感應圖型104或該第二感應圖型108的整體面積為基礎，該重疊區域面積優選為50%或以下。
此外，當本發明之感應圖型具有落於上述範圍內的間隙時，可見性可被顯著地改善。該感應圖型係藉由圖型部分與非圖型部分間之反射率差異被視覺識別。假如該感應圖型係視覺上可識別，則該觸控螢幕面板之可見性降低。本發明人構思的想法是，假如圖案部分之間的間隙為4μm或以下，則非圖案部分的面積顯著窄小以致於不會在視覺上可識別，而且這個想法完成了本發明。關於這方面，圖案間的間隙可以為4μm或以下，而且優選地，為3μm或以下。圖案間的間隙愈窄，越少的非圖案部分為可識別，因此間隙的下限並無特別的限定。
如第3圖所示，該第二感應圖案108可自該絕緣層之表面凸出，然不限於此。如有必要，該第二感應圖案108可以被該絕緣層埋入其內而形成而未自該絕緣層106之上表面凸出。
此外，本發明提供一種製作一觸控螢幕面板之方法。
第6圖為依據本發明之一實施方式，依序說明該製作觸控螢幕面板方法的視圖。
請參閱第6圖，首先，該第一感應圖型104係形成於該基底構件102上(如第6A圖)，此處，該第一感應圖型104可藉由，例如，一網印方法而形成。於此情況下，該第一感應圖型104可由金屬奈米線或金屬網所製成，然而，本發明不限於此；且該第一感應圖型104可藉由濺鍍方法、光刻方法、或任何相關技術領域中所習知之其他不同方法而形成。更進一步，該第一感應圖型104可由一導電材料，例如氧化銦錫(ITO)、石墨烯、有機電極或其類似者所製成，該導電材料為相關技術領域中所習知者且無特別限定。
其次，該絕緣層106係形成於該基底構件102上以覆蓋該第一感應圖型104(如第6B圖)。該絕緣層106可藉由沉積一無機材料或塗佈一有機材料於該基底構件102上而形成。
然後，該第二感應圖型108係於該絕緣層106之上形成(如第4C圖)，於此，當該第一及第二感應圖型104及108投影至相同平面時，該第二感應圖型108可形成具有4μm或以下之一間隙。該第二感應圖型108可藉由，例如，網印方法所形成，於此情況下，該第二感應圖型可由金屬奈米線或金屬網所製成，然而，本發明不限於此；且該第二感應圖型108可藉由濺鍍方法、光刻方法、或相關技術領域中所習知之任何其他不同方法而形成。更進一步，該第二感應圖型108可以由一導電材料，例如氧化銦錫(ITO)、石墨烯、有機電極或其類似者所製成，該導電材料為相關技術領域中所習知而無特別限定。
依據本發明的一實施方式，由於該第一感應圖型104及該第二感應圖型108係於互為不同之平面上所形成，因此可能不藉由橋接圖型或是接觸孔來互相連接排列於相同列之該各自第二感應圖型。於此情況下，由於只需要進行簡單的疊層製程即可，而無需進行光刻製程來形成該接觸孔，該觸控螢幕面板的整體製造程序可簡化，且製造時間及成本亦可降低。此外，並無因為該接觸孔的高接觸電阻所造成的導電性下降，因此該感應圖型的導電性可被維持在一預定的水準。
此外，由於該第一感應圖型104及該第二感應圖型108係於互為不同之平面上所形成，因此可能藉由網印方法形成該第一感應圖型及該第二感應圖型、以及從而製造具有大面積的觸控螢幕面板。更進一步，該第一感應圖型104及該第二感應圖型108間形成之間隙可為4μm或以下，以改善觸控靈敏性。
其次，依據本發明另一實施方式之製作觸控螢幕面板方法，將參閱第7圖說明。第7圖說明一種依據本發明之另一實施方式之製作觸控螢幕面板方法，其中，當該第一感應圖型及該第二感應圖型投影於相同平面時，該第一感應圖型及該第二感應圖型係互相重疊而形成(間隙W為負值而形成)。
如第7圖所示之製作方法，可用參閱第6圖所敘述之製作方法相同方式來進行，除了該間隙W係為負值而形成以外，亦即，該第一及第二感應圖型104及108係互相重疊，因此，相關之詳細敘述於此省略。
於此之後，較佳實施方式將參閱實施例及比較實施例被描述以更具體了解本發明。然而，於相關技術領域中具有通常知識者將理解，所提供之實施方式係作為說明之目的，並非限制如實施方式及後附申請專利範圍所揭露欲保護的主題內容。因此，顯然對於相同技術領域中具有通常知識者而言，於不脫離本發明之範疇及精神下，可能將實施例作出各種改變及修正，且都適當地包含於後附申請專利範圍所定義的範圍。
實施例
實施例1~4及比較實施例1~3
具有規則性菱形形狀之第一感應圖型，係藉由濺鍍氧化銦錫(ITO)形成於一聚醚碸(polyethersulfone，PES)高分子基板上，以及一有機絕緣層係塗佈於該第一感應圖型上，然後具有規則性菱形形狀之第二感應圖型再藉由濺鍍氧化銦錫(ITO)於該有機絕緣層上形成。
於此，當該第一及第二感應圖型104及108投影至相同平面時，該第一及第二感應圖型係被製備而具有如下方表1所述之一間隙。

[表1]
請參閱表1及第8圖，相較於比較實施例1~3之該第一感應圖型及該第二感應圖型間具有間隙大於4μm，於實施例1~4中可見，該第一感應圖型及該第二感應圖型間具有間隙為4μm或以下(特別是從具有該間隙為4μm之實施例1)之電極疊層的Cm值係增加，從而改善觸控靈敏性。
此外，於實施例2~4中可見，該第一感應圖型及該第二感應圖型間具有間隙為0μm或以下之ΔCm以及Cm值係快速增加，使觸控靈敏性更顯著增加。
同時，實施例1~4中，具有間隙為4μm或以下之該第一感應圖型及該第二感應圖型，不可能識別該感應圖型，其原因為介於該電極之該間隙係窄於可被視覺識別者的範圍。The invention discloses a touch screen panel and a manufacturing method thereof, which comprise a first sensing pattern formed on a lower surface of an insulating layer, and a second sensing pattern formed on an upper surface of the insulating layer. The first sensing pattern and the second sensing pattern are formed in mutually different directions, and when the first sensing pattern and the second sensing pattern are projected to the same plane, the first sensing The pattern and the second sensing pattern have a gap of 4 μm or less formed therebetween, thereby improving conductivity, touch sensitivity, and visibility.
As described below, a touch screen panel of the present invention and a method of fabricating the same will be described in detail with reference to the following drawings.
In the description of the present invention, a detailed description of the disclosed conventional functions and configurations that are sufficient to obscure the gist of the present invention is omitted. In addition, the terms or words used in the specification and claims should not be construed as being limited to the meaning of a vocabulary, and should be based on the concept that the inventor knows appropriate, based on the terms he or she can define. The best way others have seen to describe his or her invention.
However, it is to be understood by those skilled in the art that the present invention is to be construed as being limited by the scope of the invention. Therefore, it is apparent that various changes and modifications may be made to the embodiments without departing from the scope and spirit of the invention, and are appropriately included in the scope of the appended claims. range.
FIG. 3 is a cross-sectional view showing a touch screen panel according to an embodiment of the present invention.
Referring to FIG. 3, a touch screen panel 100 according to an embodiment of the present invention includes a base member 102, a first sensing pattern 104 formed on the base member 102, and an insulating layer 106, and is formed on A second sensing pattern 108 on the insulating layer 106.
The base member 102 can use a transparent substrate (or a film). For example, the base member 102 can be used, but is not limited to, a glass substrate or a plastic substrate. Moreover, the base member 102 can be formed from any flexible material known in the related art.
The first sensing pattern 104 is formed on the base member 102. The first sensing pattern 104 is formed on the base member 102 in a plurality of columns, and the first sensing is arranged in the same column. The patterns 104 are formed by interconnecting, and the first sensing pattern 104 may be formed in a polygonal shape. An embodiment of the polygonal shape may be a triangle, a quadrangle (diamond, a quadrangle or a square), a hexagon, or the like. However, the shape of the first sensing pattern 104 is not limited thereto, and the first sensing pattern is The shape of the pattern 104 can be formed from other different shapes. The first sensing pattern 104 may be made of a conductive material such as indium tin oxide (ITO), metal nanowire, metal mesh, graphene, organic electrode, or the like. And can be made of a transparent electrode. In the present invention, the transparent electrode refers to an electrode that is not visually identifiable, and thus the transparent electrode may include an electrode that is not visually recognizable due to its fine structure even if the material itself is not transparent.
As shown in FIG. 3, the first sensing pattern 104 can be formed by embedding the insulating layer without protruding from the surface of the insulating layer, but is not limited thereto. The first sensing pattern 104 may be formed from the surface of the insulating layer if necessary.
The insulating layer 106 is formed on the base member 102 to cover the first sensing pattern 104. The insulating layer 106 acts to electrically insulate the first sensing pattern 104 from the second sensing pattern 108 while protecting the base member 102. The insulating layer 106 may be made of an inorganic material or an organic material. When the insulating layer 106 is made of an inorganic material, the insulating layer 106 may be formed by, for example, sputtering an inorganic material such as cerium oxide. Deposited on the base member 102, when the insulating layer 106 is made of an inorganic material, the insulating layer 106 can have a durability that can be maintained within a predetermined level. Meanwhile, when the insulating layer 106 is made of an organic material, the insulating layer 106 can be formed on the base member 102 by applying an organic material, such as a photohardening resin, and hardening it. The organic material is baked at a relatively low temperature (e.g., about 220oC). Therefore, when a polarizer (not shown) is formed between the base member 102 and the insulating layer 106, the resulting polarizer (not shown) can be prevented from being destroyed by the organic material. Further, when the base member 102 is made of a flexible material, the insulating material 106 is preferably made of an organic material.
The second sensing pattern 108 is formed on the insulating layer 106. Here, the second sensing pattern 108 is formed on the base member 102 in a plurality of columns, and the second sensing patterns 108 arranged in the same column are connected to each other, that is, due to the second sensing The pattern 108 is formed on a different plane from which the first sensing pattern 104 is formed, and the respective second sensing patterns 108 arranged in the same column can be connected to each other.
The second sensing pattern 108 is formed in a different direction from the direction in which the first sensing pattern 104 is formed (for example, an orthogonal direction thereof). Therefore, the first sensing pattern 104 and the second sensing pattern 108 can be Provides information on the X and Y axis coordinates of a point that the user touches.
The second sensing pattern 108 can also be formed in a polygonal shape. An embodiment of the polygonal shape may be a triangle, a quadrangle (diamond, a quadrangle or a square), a hexagon, or the like. However, the shape of the second sensing pattern 108 is not limited thereto, and the second sensing image The shape of the pattern 108 can be formed from other different shapes. The two sensing patterns 108 may be made of a conductive material such as indium tin oxide (ITO), a metal nanowire, a metal mesh, graphene, an organic electrode, or the like, and may be made of a transparent electrode.
In the present invention, when the first sensing pattern and the second sensing pattern are projected to the same plane, the first sensing pattern and the second sensing pattern have a gap of 4 μm or less between the first sensing pattern and the second sensing pattern. Formed.
As shown in FIG. 1 and FIG. 2, in the conventional touch screen panel having the structure in which the first sensing pattern 20-1 and the second sensing pattern 20-2 are formed on the same plane, the first A sensing pattern 20-1 and the second sensing pattern 20-2 should be separated from each other due to, for example, the problem of inter-pattern interference.
However, in the touch screen panel of the present invention, the first sensing pattern 104 and the second sensing pattern 108 are formed on mutually different planes, so the first and second sensing patterns 104 and 108 may be disregarded. A gap formed therebetween is formed.
Further, the inventor conceived that the first sense is that when the first and second sensing patterns 104 and 108 are projected on the same plane, if the gap formed therebetween is 4 micrometers or less, the first sense The capacitance generated between the measurement pattern 104 and the second sensing pattern 108 is significantly increased to improve touch sensitivity, and this idea has completed the present invention.
Specifically, the touch sensitivity may be represented by a mutual capacitance (Cm) generated when the mutual capacitance is between the first sensing pattern 104 and the second sensing pattern 108 when the screen is touched, and ΔCm represents The amount of change in Cm before and after exposure to the screen.
When the screen is touched, the mutual capacitance generated between the first sensing pattern 104 and the second sensing pattern 108 is represented by Equation 1 below:
[Equation 1]
(where ε represents a dielectric constant, A represents a cross-sectional area, and d represents a distance between patterns.)
When the first sensing pattern 104 and the second sensing pattern 108 are formed close to each other, d is reduced, and thus Cm is increased.
Since ΔCm represents the amount of change in Cm before the contact screen (base Cm) and after the contact screen (contact Cm), if ΔCm is large, the difference in signal before and after the touch screen is large, that is, the touch sensitivity is excellent.
In addition, as the base Cm increases, a signal-to-noise ratio (SNR) also increases to improve touch sensitivity. That is, the SNR of the touch screen panel can be determined by the ratio of Cm to Ccell . Said. C cell refers to a cell electrode (such as a liquid crystal display (LCD) electrode, an organic light emitting diode (OLED) electrode or the like), and does not refer to the first and second sensing patterns 104 and 108, the capacitance produced. The C cell acts as a kind of noise, which is a useless capacitance in the touch screen panel. In this regard, when the gap between the first sensing pattern 104 and the second sensing pattern 108 is formed to be 4 μm or less, Compared with the example whose numerical value falls outside the above range, the basic Cm system is greatly increased and the SNR is also increased to improve the touch sensitivity.
If the gap between the first and second sensing patterns 104 and 108 falls within the above range of the present invention, the smaller the gap, the more the base Cm increases. Therefore, in the present invention, the lower limit value of the gap is not particularly limited to a range of values that maintains such a tendency, for example, the gap may be 0 (zero).
According to another embodiment of the present invention, the gap W has an example of a negative value (wherein the patterns are overlapped when the first sensing pattern and the second sensing pattern are projected onto the same plane), and also includes Within the scope of the invention. In this regard, FIG. 4 is a schematic diagram illustrating a difference between a gap between the first sensing pattern and the second sensing pattern of the touch screen panel, and FIG. 5 is a schematic diagram illustrating another embodiment according to the present invention. The gap has a negative touch panel.
When the first sensing pattern and the second sensing pattern overlap (when the gap has a negative value), ΔCm and Cm are greatly increased, so the touch sensitivity is greatly increased.
When the first and second sensing patterns are overlapped, the area of the overlapping area is not particularly limited. However, for example, based on the overall area of the first sensing pattern 104 or the second sensing pattern 108, The area of the overlap area is preferably 50% or less.
Further, when the sensing pattern of the present invention has a gap falling within the above range, the visibility can be remarkably improved. The sensing pattern is visually recognized by the difference in reflectance between the pattern portion and the non-pattern portion. If the sensing pattern is visually identifiable, the visibility of the touch screen panel is reduced. The idea conceived by the inventors is that if the gap between the pattern portions is 4 μm or less, the area of the non-pattern portion is remarkably narrow so as not to be visually identifiable, and this idea has completed the present invention. In this regard, the gap between the patterns may be 4 μm or less, and is preferably 3 μm or less. The narrower the gap between the patterns, the less the non-pattern portion is identifiable, and therefore the lower limit of the gap is not particularly limited.
As shown in FIG. 3, the second sensing pattern 108 may protrude from the surface of the insulating layer, but is not limited thereto. If necessary, the second sensing pattern 108 may be buried by the insulating layer without protruding from the upper surface of the insulating layer 106.
In addition, the present invention provides a method of making a touch screen panel.
FIG. 6 is a view sequentially illustrating a method of fabricating a touch screen panel according to an embodiment of the present invention.
Referring to FIG. 6, first, the first sensing pattern 104 is formed on the base member 102 (as shown in FIG. 6A). Here, the first sensing pattern 104 can be, for example, a screen printing method. And formed. In this case, the first sensing pattern 104 may be made of a metal nanowire or a metal mesh. However, the present invention is not limited thereto; and the first sensing pattern 104 may be by a sputtering method or a photolithography method. Or formed by any other different method as is known in the related art. Furthermore, the first sensing pattern 104 can be made of a conductive material such as indium tin oxide (ITO), graphene, an organic electrode or the like, which is known in the related art and is not Specially limited.
Next, the insulating layer 106 is formed on the base member 102 to cover the first sensing pattern 104 (as shown in FIG. 6B). The insulating layer 106 can be formed by depositing an inorganic material or coating an organic material on the base member 102.
Then, the second sensing pattern 108 is formed on the insulating layer 106 (as shown in FIG. 4C). Here, when the first and second sensing patterns 104 and 108 are projected onto the same plane, the second The sensing pattern 108 can be formed to have a gap of 4 μm or less. The second sensing pattern 108 can be formed by, for example, a screen printing method. In this case, the second sensing pattern can be made of a metal nanowire or a metal mesh. However, the invention is not limited thereto; And the second sensing pattern 108 can be formed by a sputtering method, a photolithography method, or any other different method known in the related art. Further, the second sensing pattern 108 may be made of a conductive material such as indium tin oxide (ITO), graphene, an organic electrode or the like, which is known in the related art. Specially limited.
According to an embodiment of the present invention, since the first sensing pattern 104 and the second sensing pattern 108 are formed on different planes, they may not be connected to each other by a bridge pattern or a contact hole. The respective second sensing patterns arranged in the same column. In this case, since only a simple lamination process is required, and the photolithography process is not required to form the contact hole, the overall manufacturing process of the touch screen panel can be simplified, and the manufacturing time and cost can be reduced. Further, there is no decrease in conductivity due to the high contact resistance of the contact hole, and thus the conductivity of the induction pattern can be maintained at a predetermined level.
In addition, since the first sensing pattern 104 and the second sensing pattern 108 are formed on mutually different planes, the first sensing pattern and the second sensing pattern may be formed by a screen printing method. And thereby manufacturing a touch screen panel having a large area. Further, a gap formed between the first sensing pattern 104 and the second sensing pattern 108 may be 4 μm or less to improve touch sensitivity.
Next, a method of manufacturing a touch screen panel according to another embodiment of the present invention will be described with reference to FIG. FIG. 7 illustrates a method for fabricating a touch screen panel according to another embodiment of the present invention, wherein when the first sensing pattern and the second sensing pattern are projected on the same plane, the first sensing pattern and The second sensing patterns are formed by overlapping each other (the gap W is formed by a negative value).
The manufacturing method as shown in Fig. 7 can be carried out in the same manner as the manufacturing method described in Fig. 6, except that the gap W is formed to be a negative value, that is, the first and second sensing patterns 104. Since the 108 series overlap each other, the detailed description is omitted here.
Hereinafter, the preferred embodiments will be described with reference to the embodiments and comparative examples to more specifically understand the present invention. However, those skilled in the art will understand that the embodiments are provided for the purpose of illustration, and are not intended to limit the scope of the claimed subject matter. Therefore, it is apparent that various changes and modifications may be made to the embodiments without departing from the scope and spirit of the invention, and are appropriately included in the scope of the appended claims. range.
Examples Examples 1 to 4 and Comparative Examples 1 to 3

Here, when the first and second sensing patterns 104 and 108 are projected onto the same plane, the first and second sensing patterns are prepared to have a gap as described in Table 1 below.
In addition, the Cm and ΔCm of the prepared electrode laminates were measured, and whether the pattern was visually identifiable was also confirmed. The results are shown in Table 1 below and Figure 8 below.
[Table 1]
Referring to Tables 1 and 8, the first sensing pattern and the second sensing pattern have a gap of more than 4 μm compared with the first embodiment, and the first one can be seen in the first to fourth embodiments. The Cm value of the electrode stack having a gap of 4 μm or less between the sensing pattern and the second sensing pattern (especially from Example 1 having the gap of 4 μm) is increased, thereby improving touch sensitivity.
In addition, as shown in the embodiments 2 to 4, the ΔCm and the Cm value of the first sensing pattern and the second sensing pattern having a gap of 0 μm or less are rapidly increased, so that the touch sensitivity is more significantly increased.
Meanwhile, in the first to fourth embodiments, the first sensing pattern and the second sensing pattern having a gap of 4 μm or less are impossible to identify the sensing pattern because the gap between the electrodes is narrow. To the extent that it can be visually recognized.
