Description

觸控基板Touch substrate

本發明是有關於一種觸控技術,且特別是有關於一種觸控基板。The present invention relates to a touch technology, and particularly relates to a touch substrate.

近年來,人們對電子產品之依賴性與日俱增。為了達到更便利、體積更輕巧化以及更人性化的目的,許多資訊產品的輸入裝置已由傳統的鍵盤或滑鼠轉變為觸控面板,其中具有觸控功能的顯示面板更成為現今行動裝置的標準配備。因具有反應快、可靠度佳以及耐用度高等優點,電容式觸控技術已成為目前觸控技術的主流,並廣泛地運用在相關的電子產品(例如手機、平板電腦或智慧型手錶)中。依據觸控技術與顯示面板的整合方式,電容式觸控顯示面板大致上可區分為外貼式(out-cell)、外嵌式(on-cell)與內嵌式(in-cell)三種。In recent years, people's dependence on electronic products has increased day by day. In order to achieve the purpose of more convenience, lighter size and more user-friendliness, the input devices of many information products have been transformed from traditional keyboards or mice to touch panels. Among them, the display panel with touch function has become the current mobile device. Standard equipment. Due to the advantages of fast response, good reliability, and high durability, capacitive touch technology has become the mainstream of current touch technology and is widely used in related electronic products (such as mobile phones, tablets, or smart watches). According to the integration method of touch technology and display panel, capacitive touch display panels can be roughly divided into three types: out-cell, on-cell, and in-cell.

一般而言,外貼式或整合式的觸控顯示面板會將觸控電極層設置在顯示面板靠近使用者的一側上,使觸控電極能較佳地感測到使用者的觸控。為了增加感測訊號的傳遞速度(或感測頻率),觸控電極層大都採用金屬材料。也因此,外界環境光照射在觸控電極層上時容易產生反射,導致圖案化的觸控電極被人眼所視覺,進而造成觸控顯示面板的顯示品質下降。Generally speaking, in an externally attached or integrated touch display panel, the touch electrode layer is arranged on the side of the display panel close to the user, so that the touch electrode can better sense the user's touch. In order to increase the transmission speed (or sensing frequency) of the sensing signal, most of the touch electrode layer is made of metal materials. Therefore, when external ambient light is irradiated on the touch electrode layer, reflection is likely to occur, resulting in the patterned touch electrode being visualized by human eyes, and thus the display quality of the touch display panel is degraded.

請參照圖1,觸控基板10包括基板100以及設置於基板100上的多個觸控感測單元TSU。這些觸控感測單元TSU可陣列排列於基板100上。舉例來說,多個觸控感測單元TSU可分別沿著方向X與方向Y排成多列與多行,且彼此電性連接。在本實施例中,方向X可垂直於方向Y,但不以此為限。基板100的材質可包括玻璃、石英、有機聚合物、或其他適合的材料。特別說明的是,本實施例的基板100可以是顯示面板的顯示側的基板。也就是說,上述的觸控感測單元TSU可直接製作在顯示面板一側的基板表面上,以形成外嵌式(on-cell)的觸控顯示面板。然而,本發明不限於此,根據其他實施例,觸控基板也可直接貼合於顯示面板的顯示側以形成外貼式(out-cell)的觸控顯示面板。Please refer to FIG. 1, the touch substrate 10 includes a substrate 100 and a plurality of touch sensing units TSU disposed on the substrate 100. The touch sensing units TSU may be arranged in an array on the substrate 100. For example, the multiple touch sensing units TSU may be arranged in multiple columns and multiple rows along the direction X and the direction Y, and are electrically connected to each other. In this embodiment, the direction X can be perpendicular to the direction Y, but it is not limited thereto. The material of the substrate 100 may include glass, quartz, organic polymer, or other suitable materials. Specifically, the substrate 100 of this embodiment may be a substrate on the display side of a display panel. In other words, the aforementioned touch sensing unit TSU can be directly fabricated on the surface of the substrate on one side of the display panel to form an on-cell touch display panel. However, the present invention is not limited to this. According to other embodiments, the touch substrate can also be directly attached to the display side of the display panel to form an out-cell touch display panel.

觸控感測單元TSU包括彼此相交的第一觸控電極TE1與第二觸控電極TE2。舉例而言,沿著方向X排成一列的多個觸控感測單元TSU的多個第一觸控電極TE1彼此電性連接以形成第一觸控訊號線TL1,且此第一觸控訊號線TL1大致上沿著方向X延伸。沿著方向Y排成一行的多個觸控感測單元TSU的多個第二觸控電極TE2彼此電性連接以形成第二觸控訊號線TL2,且此第二觸控訊號線TL2大致上沿著方向Y延伸。舉例而言,在本實施例中,第一觸控訊號線TL1與第二觸控訊號線TL2是以來回彎折的方式分別在方向X與方向Y上延伸,但本發明不以此為限。The touch sensing unit TSU includes a first touch electrode TE1 and a second touch electrode TE2 that intersect each other. For example, the plurality of first touch electrodes TE1 of the plurality of touch sensing units TSU arranged in a row along the direction X are electrically connected to each other to form a first touch signal line TL1, and this first touch signal The line TL1 extends substantially along the direction X. The plurality of second touch electrodes TE2 of the plurality of touch sensing units TSU arranged in a row along the direction Y are electrically connected to each other to form a second touch signal line TL2, and the second touch signal line TL2 is substantially Extend in direction Y. For example, in the present embodiment, the first touch signal line TL1 and the second touch signal line TL2 extend in the direction X and the direction Y respectively in a bending manner, but the invention is not limited to this .

在本實施例中,第一觸控訊號線TL1與第二觸控訊號線TL2可分別用以傳遞觸控驅動訊號與觸控感側訊號。也就是說,觸控感測單元TSU的第一觸控電極TE1可以是驅動電極(或者是發送電極),第二觸控電極TE2可以是接收電極(或者是感側電極),但本發明不以此為限。在其他實施例中,第一觸控電極TE1與第二觸控電極TE2也可分別為接收電極與驅動電極。In this embodiment, the first touch signal line TL1 and the second touch signal line TL2 can be used to transmit touch driving signals and touch-sensing side signals, respectively. That is, the first touch electrode TE1 of the touch sensing unit TSU may be a driving electrode (or a transmitting electrode), and the second touch electrode TE2 may be a receiving electrode (or a sensing electrode), but the present invention does not Limit this. In other embodiments, the first touch electrode TE1 and the second touch electrode TE2 may also be receiving electrodes and driving electrodes, respectively.

觸控感測單元TSU更包括設置於第一觸控電極TE1與第二觸控電極TE2之間的虛設電極DE。在本實施例中,相鄰的兩條第一觸控訊號線TL1相交於相鄰的兩條第二觸控訊號線TL2可定義出一開口OP,且虛設電極DE設置於此開口OP內。虛設電極DE於基板100上的垂直投影不重疊於第一觸控電極TE1(或第一觸控訊號線TL1)和第二觸控電極TE2(或第二觸控訊號線TL2)於基板100上的垂直投影。特別一提的是,虛設電極DE電性獨立於第一觸控電極TE1與第二觸控電極TE2。更具體地說,虛設電極DE具有浮置電位(floating potential)。亦即,虛設電極DE並未電性連接至任何的訊號源。The touch sensing unit TSU further includes a dummy electrode DE disposed between the first touch electrode TE1 and the second touch electrode TE2. In this embodiment, two adjacent first touch signal lines TL1 intersect with two adjacent second touch signal lines TL2 to define an opening OP, and the dummy electrode DE is disposed in the opening OP. The vertical projection of the dummy electrode DE on the substrate 100 does not overlap the first touch electrode TE1 (or the first touch signal line TL1) and the second touch electrode TE2 (or the second touch signal line TL2) on the substrate 100 Vertical projection. In particular, the dummy electrode DE is electrically independent of the first touch electrode TE1 and the second touch electrode TE2. More specifically, the dummy electrode DE has a floating potential. That is, the dummy electrode DE is not electrically connected to any signal source.

值得一提的是,每一觸控感測單元TSU的第一觸控電極TE1與第二觸控電極TE2的總反射率(total reflectance)與虛設電極DE的反射率的差值小於3%。據此,可有效降低圖案化觸控電極(例如第一觸控電極TE1與第二觸控電極TE2)在外界環境光照射下的可視性,進而提升觸控顯示面板的顯示品質。It is worth mentioning that the difference between the total reflectance of the first touch electrode TE1 and the second touch electrode TE2 of each touch sensing unit TSU and the reflectance of the dummy electrode DE is less than 3%. Accordingly, the visibility of the patterned touch electrodes (for example, the first touch electrode TE1 and the second touch electrode TE2) under external ambient light irradiation can be effectively reduced, thereby improving the display quality of the touch display panel.

在本實施例中,在結構上彼此分離開來的第一觸控電極TE1、第二觸控電極TE2與虛設電極DE可選擇性地屬於同一膜層。也就是說,第一觸控電極TE1、第二觸控電極TE2與虛設電極DE的材質可相同。然而,本發明不限於此,根據其他實施例,第一觸控電極TE1、第二觸控電極TE2與虛設電極DE的至少一者也可屬於不同的膜層。在本實施例中,第一觸控電極TE1、第二觸控電極TE2與虛設電極DE的材質為金屬(例如鋁、鈦、鉬、或上述的組合),但不以此為限。在其他實施例中,第一觸控電極TE1、第二觸控電極TE2與虛設電極DE的材質也可包括金屬類導體與非金屬類導體(例如銦錫氧化物)。In this embodiment, the first touch electrode TE1, the second touch electrode TE2, and the dummy electrode DE that are structurally separated from each other can selectively belong to the same film layer. That is, the materials of the first touch electrode TE1, the second touch electrode TE2 and the dummy electrode DE may be the same. However, the present invention is not limited to this. According to other embodiments, at least one of the first touch electrode TE1, the second touch electrode TE2, and the dummy electrode DE may also belong to different film layers. In this embodiment, the material of the first touch electrode TE1, the second touch electrode TE2, and the dummy electrode DE is metal (for example, aluminum, titanium, molybdenum, or a combination of the foregoing), but not limited thereto. In other embodiments, the materials of the first touch electrode TE1, the second touch electrode TE2 and the dummy electrode DE may also include metallic conductors and non-metallic conductors (for example, indium tin oxide).

請同時參照圖2,第一觸控電極TE1具有排列成網狀的多條第一導線110與多條第二導線120。亦即,這些第一導線110與這些第二導線120相交設置並形成第一金屬網格(metal mesh)。相似地,第二觸控電極TE2具有多條第三導線210與多條第四導線220,且這些第三導線210與這些第四導線220相交設置並形成第二金屬網格。虛設電極DE具有多條第一虛設導線310與多條第二虛設導線320,且這些第一虛設導線310與這些第二虛設導線320相交設置並形成虛設金屬網格。在本實施例中,由於第一觸控電極TE1、第二觸控電極TE2與虛設電極DE屬於同一膜層,第一金屬網格、第二金屬網格以及虛設金屬網格的任兩者之間都設有多個斷開處,以確保第一觸控電極TE1、第二觸控電極TE2與虛設電極DE之間的電性獨立。Please also refer to FIG. 2, the first touch electrode TE1 has a plurality of first conductive lines 110 and a plurality of second conductive lines 120 arranged in a mesh shape. That is, the first wires 110 and the second wires 120 are intersected and arranged to form a first metal mesh. Similarly, the second touch electrode TE2 has a plurality of third wires 210 and a plurality of fourth wires 220, and the third wires 210 and the fourth wires 220 are intersected to form a second metal grid. The dummy electrode DE has a plurality of first dummy wires 310 and a plurality of second dummy wires 320, and the first dummy wires 310 and the second dummy wires 320 are intersected to form a dummy metal grid. In this embodiment, since the first touch electrode TE1, the second touch electrode TE2, and the dummy electrode DE belong to the same film layer, any two of the first metal mesh, the second metal mesh, and the dummy metal mesh There are multiple disconnections between them to ensure electrical independence between the first touch electrode TE1, the second touch electrode TE2 and the dummy electrode DE.

進一步而言,在觸控基板10的局部區域I內,第一觸控電極TE1的第一導線110的延伸方向大致上平行於第一觸控電極TE1的延伸方向。第一觸控電極TE1的第二導線120的延伸方向相交於第一觸控電極TE1的延伸方向,且第二導線120具有斷開處CT1。值得注意的是,這些第二導線120上的多個斷開處CT1的虛擬連線CL1與相鄰的第一導線110錯開。換句話說,第二導線120上的這些斷開處CT1在基板100上的垂直投影不重疊於第一導線110在基板100上的垂直投影。Furthermore, in the local area I of the touch substrate 10, the extension direction of the first wire 110 of the first touch electrode TE1 is substantially parallel to the extension direction of the first touch electrode TE1. The extension direction of the second wire 120 of the first touch electrode TE1 intersects the extension direction of the first touch electrode TE1, and the second wire 120 has a disconnection CT1. It should be noted that the virtual lines CL1 of the multiple disconnections CT1 on the second conductive lines 120 are staggered from the adjacent first conductive lines 110. In other words, the vertical projection of the disconnection CT1 on the substrate 100 on the second wire 120 does not overlap the vertical projection of the first wire 110 on the substrate 100.

相似地,在觸控基板10的局部區域I內,第二觸控電極TE2的第三導線210的延伸方向大致上平行於第二觸控電極TE2的延伸方向。第二觸控電極TE2的第四導線220的延伸方向相交於第二觸控電極TE2的延伸方向,且第四導線220具有斷開處CT2。值得注意的是,這些第四導線220上的多個斷開處CT2的虛擬連線CL2與相鄰的第三導線210錯開。換句話說,第四導線220上的這些斷開處CT2在基板100上的垂直投影不重疊於第三導線210在基板100上的垂直投影。不同於第一觸控電極TE1與第二觸控電極TE2,虛設電極DE的第一虛設導線310與第二虛設導線320上都設有斷開處CT3。Similarly, in the local area I of the touch substrate 10, the extension direction of the third wire 210 of the second touch electrode TE2 is substantially parallel to the extension direction of the second touch electrode TE2. The extension direction of the fourth wire 220 of the second touch electrode TE2 intersects the extension direction of the second touch electrode TE2, and the fourth wire 220 has a disconnection CT2. It is worth noting that the virtual lines CL2 of the multiple disconnections CT2 on the fourth wires 220 are staggered from the adjacent third wires 210. In other words, the vertical projection of the disconnection CT2 on the fourth wire 220 on the substrate 100 does not overlap the vertical projection of the third wire 210 on the substrate 100. Different from the first touch electrode TE1 and the second touch electrode TE2, both the first dummy wire 310 and the second dummy wire 320 of the dummy electrode DE are provided with a disconnection CT3.

值得一提的是,第一觸控電極TE1上的各斷開處CT1在對應的第二導線120的延伸方向上具有寬度W1。第二觸控電極TE2上的各斷開處CT2在對應的第四導線220的延伸方向上具有寬度W2。在本實施例中,第一觸控電極TE1的斷開處CT1的寬度W1可等於第二觸控電極TE2的斷開處CT2的寬度W2,但本發明不以此為限。在其他實施例中,第一觸控電極TE1的斷開處CT1的寬度W1與第二觸控電極TE2的斷開處CT2的寬度W2也可不相等。It is worth mentioning that each disconnection CT1 on the first touch electrode TE1 has a width W1 in the extending direction of the corresponding second wire 120. Each disconnection CT2 on the second touch electrode TE2 has a width W2 in the extending direction of the corresponding fourth wire 220. In this embodiment, the width W1 of the disconnection CT1 of the first touch electrode TE1 may be equal to the width W2 of the disconnection CT2 of the second touch electrode TE2, but the invention is not limited thereto. In other embodiments, the width W1 of the disconnection CT1 of the first touch electrode TE1 and the width W2 of the disconnection CT2 of the second touch electrode TE2 may not be equal.

另一方面,虛設電極DE上的各斷開處CT3在對應的第一虛設導線310或第二虛設導線320的延伸方向上具有寬度W3。在本實施例中,第一觸控電極TE1的斷開處CT1的寬度W1以及第二觸控電極TE2的斷開處CT2的寬度W2可大於虛設電極DE的斷開處CT3的寬度W3。據此,可有效縮減第一觸控電極TE1和第二觸控電極TE2的總反射率與虛設電極DE的反射率的差值,進而降低圖案化觸控電極(例如第一觸控電極TE1與第二觸控電極TE2)在外界環境光照射下的可視性。然而,本發明不限於此,根據其他實施例,第一觸控電極TE1的斷開處CT1的寬度W1以及第二觸控電極TE2的斷開處CT2的寬度W2也可等於虛設電極DE的斷開處CT3的寬度W3。On the other hand, each disconnection CT3 on the dummy electrode DE has a width W3 in the extending direction of the corresponding first dummy wire 310 or the second dummy wire 320. In this embodiment, the width W1 of the disconnection CT1 of the first touch electrode TE1 and the width W2 of the disconnection CT2 of the second touch electrode TE2 may be larger than the width W3 of the disconnection CT3 of the dummy electrode DE. Accordingly, the difference between the total reflectivity of the first touch electrode TE1 and the second touch electrode TE2 and the reflectivity of the dummy electrode DE can be effectively reduced, thereby reducing the patterned touch electrodes (such as the first touch electrode TE1 and the The visibility of the second touch electrode TE2) under ambient light irradiation. However, the present invention is not limited to this. According to other embodiments, the width W1 of the disconnection CT1 of the first touch electrode TE1 and the width W2 of the disconnection CT2 of the second touch electrode TE2 may also be equal to the disconnection of the dummy electrode DE. The width of the opening CT3 is W3.

特別說明的是,由於第一觸控電極TE1的斷開處CT1是設置在與電流I 1的主要傳導路徑(例如第一導線110)相交的第二導線120上,對於電流I 1的傳導效率並不會有實質上的影響。相同地,由於第二觸控電極TE2的斷開處CT2是設置在與電流I 2的主要傳導路徑(例如第三導線210)相交的第四導線220上,對於電流I 2的傳導效率並不會有實質上的影響。換句話說,透過上述斷開處CT1與斷開處CT2的設置方式,可避免第一觸控電極TE1與第二觸控電極TE2的電阻值增加。 In particular, since the disconnection CT1 of the first touch electrode TE1 is set on the second wire 120 that intersects the main conduction path of the current I 1 (for example, the first wire 110), the conduction efficiency of the current I 1 is There will be no substantial impact. Similarly, since the disconnection CT2 of the second touch electrode TE2 is set on the fourth wire 220 that intersects the main conduction path of the current I 2 (for example, the third wire 210), the conduction efficiency of the current I 2 is not There will be a substantial impact. In other words, through the arrangement of the disconnection CT1 and the disconnection CT2, the resistance value of the first touch electrode TE1 and the second touch electrode TE2 can be prevented from increasing.

請參照圖2及圖4,,由於本實施例的第一觸控電極TE1與第二觸控電極TE2是屬於同一膜層,每一觸控感測單元TSU的第二觸控電極TE2在與第一觸控電極TE1的相交處還具有斷開處CT4,且第二觸控電極TE2位於斷開處CT4兩側的兩部分可透過一橋接圖案250而電性連接於彼此。舉例來說,此橋接圖案250與第二觸控電極TE2(或第一觸控電極TE1)屬於不同的導電膜層,且橋接圖案250的兩端部可透過位於兩導電膜層之間的絕緣層的兩接觸窗251分別電性連接第二觸控電極TE2的上述兩部分,以達到橋接的目的。然而,本發明不限於此,在其他實施例中,每一觸控感測單元TSU也可以是第一觸控電極TE1在與第二觸控電極TE2的相交處具有斷開處,並且透過上述的方式進行橋接。2 and 4, since the first touch electrode TE1 and the second touch electrode TE2 of this embodiment belong to the same film layer, the second touch electrode TE2 of each touch sensing unit TSU is in contact with each other. The intersection of the first touch electrode TE1 also has a disconnection CT4, and the two parts of the second touch electrode TE2 on both sides of the disconnection CT4 can be electrically connected to each other through a bridge pattern 250. For example, the bridge pattern 250 and the second touch electrode TE2 (or the first touch electrode TE1) belong to different conductive film layers, and the two ends of the bridge pattern 250 can pass through the insulation between the two conductive film layers. The two contact windows 251 of the layer are respectively electrically connected to the above two parts of the second touch electrode TE2 to achieve the purpose of bridging. However, the present invention is not limited to this. In other embodiments, each touch sensing unit TSU may also have a disconnection at the intersection of the first touch electrode TE1 and the second touch electrode TE2, and pass through the above Way to bridge.

請參照圖1及圖3,在觸控基板10的局部區域II內,第一觸控電極TE1具有第一延伸部TE1a與第二延伸部TE1b。詳細而言,第一延伸部TE1a的第二導線120的延伸方向相交於第一延伸部TE1a的延伸方向,且第一延伸部TE1a的第二導線120設有斷開處CT1a。第一延伸部TE1a的多條第二導線120的多個斷開處CT1a的虛擬連線CL1與第一延伸部TE1a的第一導線110錯開。換句話說,第一延伸部TE1a的多條第二導線120的這些斷開處CT1a在基板100上的垂直投影不重疊於第一延伸部TE1a的第一導線110在基板100上的垂直投影。1 and 3, in the partial area II of the touch substrate 10, the first touch electrode TE1 has a first extension portion TE1a and a second extension portion TE1b. In detail, the extension direction of the second wire 120 of the first extension TE1a intersects the extension direction of the first extension TE1a, and the second wire 120 of the first extension TE1a has a break CT1a. The virtual line CL1 of the multiple disconnections CT1a of the multiple second conductive lines 120 of the first extension portion TE1a is staggered from the first conductive line 110 of the first extension portion TE1a. In other words, the vertical projections of the disconnections CT1a of the plurality of second wires 120 of the first extension TE1a on the substrate 100 do not overlap with the vertical projections of the first wires 110 of the first extension TE1a on the substrate 100.

另一方面,第二延伸部TE1b的第一導線110的延伸方向相交於第二延伸部TE1b的延伸方向,且第二延伸部TE1b的第一導線110設有斷開處CT1b。第二延伸部TE1b的多條第一導線110的多個斷開處CT1b的虛擬連線CL3與第二延伸部TE1b的第二導線120錯開。換句話說,第二延伸部TE1b的多條第一導線110的這些斷開處CT1b在基板100上的垂直投影不重疊於第二延伸部TE1b的第二導線120在基板100上的垂直投影。On the other hand, the extension direction of the first wire 110 of the second extension portion TE1b intersects the extension direction of the second extension portion TE1b, and the first wire 110 of the second extension portion TE1b has a disconnection CT1b. The virtual line CL3 of the multiple disconnections CT1b of the multiple first wires 110 of the second extension portion TE1b is staggered from the second wire 120 of the second extension portion TE1b. In other words, the vertical projections of the disconnections CT1b of the plurality of first wires 110 of the second extension portion TE1b on the substrate 100 do not overlap with the vertical projections of the second wires 120 of the second extension portion TE1b on the substrate 100.

應注意的是,在觸控基板10的局部區域II內,第一觸控電極TE1的兩個延伸部的延伸方向是不同的。因此,這兩個延伸部的斷開處都設置在與電流的主要傳遞路徑相交的導線上。據此,可避免第一觸控電極TE1的整體電阻值增加。進一步而言,第一延伸部TE1a的斷開處CT1a在對應的第二導線120的延伸方向上具有寬度W1a。第二延伸部TE1b的斷開處CT1b在對應的第一導線110的延伸方向上具有寬度W1b。在本實施例中,第一延伸部TE1a的斷開處CT1a的寬度W1a等於第二延伸部TE1b的斷開處TE1b的寬度W1b,但本發明不以此為限。在其他實施例中,這兩個斷開處的寬度大小關係也可根據觸控電極的實際設計(例如兩延伸部的寬度大小關係)而調整。It should be noted that in the partial area II of the touch substrate 10, the extension directions of the two extension portions of the first touch electrode TE1 are different. Therefore, the breaks of these two extensions are both provided on the wires that intersect the main transmission path of the current. Accordingly, the increase in the overall resistance of the first touch electrode TE1 can be avoided. Furthermore, the disconnection CT1a of the first extension portion TE1a has a width W1a in the extension direction of the corresponding second wire 120. The disconnection CT1b of the second extension portion TE1b has a width W1b in the extension direction of the corresponding first wire 110. In this embodiment, the width W1a of the disconnection CT1a of the first extension portion TE1a is equal to the width W1b of the disconnection TE1b of the second extension portion TE1b, but the invention is not limited thereto. In other embodiments, the relationship between the width of the two disconnections can also be adjusted according to the actual design of the touch electrode (for example, the relationship between the width of the two extensions).

另一方面,在本實施例中,第二觸控電極TE2也可具有延伸方向彼此相交的兩延伸部,分別為第一延伸部TE2a和第二延伸部TE2b。第二觸控電極TE2的這兩延伸部上的斷開處也可以相似於第一觸控電極TE1的兩延伸部的斷開處的配置方式進行設置,以避免第二觸控電極TE2的整體電阻值增加。具體的實施方法可參考前述針對第一觸控電極TE1的兩延伸部的斷開處的詳細說明,於此便不再贅述。On the other hand, in this embodiment, the second touch electrode TE2 may also have two extension portions whose extension directions intersect each other, namely, a first extension portion TE2a and a second extension portion TE2b. The disconnection on the two extensions of the second touch electrode TE2 can also be configured similarly to the configuration of the disconnection of the two extensions of the first touch electrode TE1, so as to avoid the whole of the second touch electrode TE2. The resistance value increases. For the specific implementation method, please refer to the foregoing detailed description of the disconnection of the two extension parts of the first touch electrode TE1, which will not be repeated here.

值得一提的是,透過第一觸控電極TE1的兩延伸部的斷開處的寬度(即寬度W1a與寬度W1b)大於虛設電極DE的斷開處CT3的寬度W3,可有效縮減第一觸控電極TE1的反射率與虛設電極DE的反射率的差值。應可理解的是,透過第二觸控電極TE2的兩延伸部(即第一延伸部TE2a和第二延伸部TE2b)的斷開處(未繪示)的寬度大於虛設電極DE的斷開處CT3的寬度W3,可進一步縮減第一觸控電極TE1和第二觸控電極TE2的總反射率與虛設電極DE的反射率的差值,進而降低圖案化觸控電極在外界環境光照射下的可視性。然而,本發明不限於此,根據其他實施例,觸控電極的兩延伸部的斷開處的寬度也可等於虛設電極DE的斷開處CT3的寬度W3。It is worth mentioning that the width (ie width W1a and width W1b) of the disconnection of the two extensions of the first touch electrode TE1 is greater than the width W3 of the disconnection CT3 of the dummy electrode DE, which can effectively reduce the first touch The difference between the reflectivity of the control electrode TE1 and the reflectivity of the dummy electrode DE. It should be understood that the width of the disconnection (not shown) between the two extensions (ie, the first extension TE2a and the second extension TE2b) of the second touch electrode TE2 is larger than the disconnection of the dummy electrode DE The width W3 of CT3 can further reduce the difference between the total reflectivity of the first touch electrode TE1 and the second touch electrode TE2 and the reflectivity of the dummy electrode DE, thereby reducing the patterned touch electrode under the external ambient light. Visibility. However, the present invention is not limited to this. According to other embodiments, the width of the disconnection of the two extension portions of the touch electrode may also be equal to the width W3 of the disconnection CT3 of the dummy electrode DE.

圖5是本發明的另一實施例的觸控基板的俯視示意圖。請參照圖5,本實施例的觸控基板11與圖3的觸控基板10的差異在於:觸控電極的兩延伸部的斷開處的寬度不同。在本實施例中,觸控基板11的第一觸控電極TE1’的第二延伸部TE1b’的斷開處CT1b’的寬度W1b’小於第一觸控電極TE1’的第一延伸部TE1a的斷開處CT1a的寬度W1a,且大於虛設電極DE的斷開處CT3的寬度W3。FIG. 5 is a schematic top view of a touch substrate according to another embodiment of the invention. Please refer to FIG. 5, the difference between the touch substrate 11 of this embodiment and the touch substrate 10 of FIG. 3 is that the widths of the breaks of the two extension portions of the touch electrodes are different. In this embodiment, the width W1b' of the disconnection CT1b' of the second extension portion TE1b' of the first touch electrode TE1' of the touch substrate 11 is smaller than that of the first extension portion TE1a of the first touch electrode TE1' The width W1a of the disconnection CT1a is greater than the width W3 of the disconnection CT3 of the dummy electrode DE.

值得一提的是,透過第一觸控電極TE1’的兩延伸部的斷開處的寬度(即寬度W1a與寬度W1b’)大於虛設電極DE的斷開處CT3的寬度W3,可有效縮減第一觸控電極TE1’的反射率與虛設電極DE的反射率的差值。應可理解的是,第二觸控電極TE2的斷開處也可透過如上述第一觸控電極TE1’的斷開處的配置方式進行設置。據此,可進一步縮減第一觸控電極TE1’和第二觸控電極TE2的總反射率與虛設電極DE的反射率的差值,進而降低圖案化觸控電極在外界環境光照射下的可視性。It is worth mentioning that the width of the disconnection between the two extensions of the first touch electrode TE1' (ie width W1a and width W1b') is greater than the width W3 of the disconnection CT3 of the dummy electrode DE, which can effectively reduce the The difference between the reflectivity of a touch electrode TE1' and the reflectivity of the dummy electrode DE. It should be understood that the disconnection of the second touch electrode TE2 can also be set through the above-mentioned configuration of the disconnection of the first touch electrode TE1'. Accordingly, the difference between the total reflectivity of the first touch electrode TE1' and the second touch electrode TE2 and the reflectivity of the dummy electrode DE can be further reduced, thereby reducing the visibility of the patterned touch electrode under ambient light irradiation. Sex.

綜上所述,在本發明的一實施例的觸控基板中,第一觸控電極與第二觸控電極相交設置,且這兩觸控電極之間設有虛設電極。此虛設電極在基板上的垂直投影不重疊於第一觸控電極與第二觸控電極在基板上的垂直投影。透過每一觸控感測單元的第一觸控電極與第二觸控電極的總反射率和虛設電極的反射率的差值小於3%,可有效降低圖案化觸控電極在外界環境光照射下的可視性(visibility),進而提升觸控顯示面板的顯示品質。To sum up, in the touch substrate of an embodiment of the present invention, the first touch electrode and the second touch electrode are intersected, and a dummy electrode is provided between the two touch electrodes. The vertical projection of the dummy electrode on the substrate does not overlap the vertical projection of the first touch electrode and the second touch electrode on the substrate. The difference between the total reflectivity of the first touch electrode and the second touch electrode and the reflectivity of the dummy electrode through each touch sensing unit is less than 3%, which can effectively reduce the exposure of the patterned touch electrode to ambient light Under the visibility (visibility), and then improve the display quality of the touch display panel.
