Description
本發明係一種觸控面板，尤指一種具靜電防護功能的觸控面板。The present invention relates to a touch panel, and more particularly to a touch panel with an electrostatic protection function.
自然界的各種物質，會因為摩擦或感應起電造成電子在不同物質間的轉移，即為靜電，當電子轉移過多導致不同物質間的電位差過大時，便會由一放電路徑放電來平衡電位，而此現象便稱為靜電放電現象。然係現有的電子產品中都有許多的訊號導線來傳導訊號，而這些訊號導線均可能會成為靜電放電的放電路徑。現有的電子產品都以輕薄短小為訴求，因此訊號導線也必須越來越細，讓該電子產品的總體積得以進一步的縮小。但越細的訊號導線，當有靜電放電產生時，越容易被靜電放電時產生的大電流損毀，造成訊號導線破裂以至於無法繼續傳送訊號，致使該電子產品無法繼續使用。因此電子產品勢必要做靜電防護，才能防止靜電放電導致的訊號導線損毀。A variety of substances in nature will cause electrons to transfer between different substances due to friction or induced electrification, that is, static electricity. When the electron transfer is too much, the potential difference between different substances is too large, and a discharge path is discharged to balance the potential. This phenomenon is called electrostatic discharge. However, there are many signal wires in the existing electronic products to conduct signals, and these signal wires may become the discharge path of the electrostatic discharge. The existing electronic products are all demanding in terms of lightness and thinness, so the signal wires must also be thinner and finer, so that the total volume of the electronic products can be further reduced. However, the thinner the signal wire, the more easily it is generated by the electrostatic discharge when the electrostatic discharge is generated, the signal wire is broken and the signal cannot be continuously transmitted, so that the electronic product cannot be used any more. Therefore, it is necessary for electronic products to be electrostatically protected to prevent damage to the signal wires caused by electrostatic discharge.
請參閱圖7所示，一般電子產品，以智慧型手機為例，係具有一觸控面板60，而該觸控面板60上具有複數電極61，而各電極61係分佈於一觸控區62內，且分別電性連接有一訊號導線611，各訊號導線611係在該觸控區62外圍佈線，並電性走線至該觸控區62外圍一側的一接合區63。而在該觸控區62周圍且環繞於各訊號導線611外，係設置有一接地導線64，該接地導線64電性連接一軟性電路板70，並透過軟性電路板70電性連接至一系統接地端(圖未示)，以形成一放電路徑。當靜電放電產生時，係由該觸控面板60的四周外圍饋入，會先透過該接地導線64將靜電導入該系統接地端，因此靜電便不會藉由該訊號導線611形成放電路徑，而可直接由該接地導線64將靜電釋放，以保護內部的訊號導線611。As shown in FIG. 7 , a general electronic product, which is a smart phone, has a touch panel 60 , and the touch panel 60 has a plurality of electrodes 61 , and the electrodes 61 are distributed in a touch area 62 . Each of the signal wires 611 is electrically connected to the periphery of the touch area 62 and electrically routed to a junction area 63 on the peripheral side of the touch area 62. A grounding conductor 64 is disposed around the touch panel 62 and surrounding the signal wires 611. The grounding conductor 64 is electrically connected to a flexible circuit board 70 and electrically connected to a system ground through the flexible circuit board 70. Ends (not shown) to form a discharge path. When the electrostatic discharge is generated, it is fed from the periphery of the touch panel 60, and the static electricity is first introduced into the grounding end of the system through the grounding wire 64. Therefore, the static electricity does not form a discharge path by the signal wire 611. Electrostatic discharge can be directly released by the ground conductor 64 to protect the internal signal conductor 611.
但，設置於該觸控區62周圍的接地導線64的線寬與該訊號導線611之線寬相差不大，因此當靜電放電的電壓過大時，便無法完全的由該接地導線64將靜電完全釋放，而導致來不及釋放的靜電進一步導入該訊號導線611，使該訊號導線611損毀。故，現有技術的接地導線64已無法有效的將靜電放電排除，以保護內部的訊號線路。However, the line width of the grounding wire 64 disposed around the touch area 62 is not much different from the line width of the signal wire 611. Therefore, when the voltage of the electrostatic discharge is too large, the static electricity can not be completely completely removed by the grounding wire 64. The static electricity that is released, which is too late to be released, is further introduced into the signal wire 611 to damage the signal wire 611. Therefore, the prior art grounding conductor 64 has been unable to effectively discharge the electrostatic discharge to protect the internal signal line.
有鑑於現有技術的缺點，本發明係提供一種靜電防護觸控面板，能具有更強的抵抗靜電放電的能力，以保護內部訊號電路，使該內部的訊號電路更為耐用。In view of the shortcomings of the prior art, the present invention provides an electrostatic protection touch panel capable of being more resistant to electrostatic discharge to protect the internal signal circuit and make the internal signal circuit more durable.

The sensing substrate 10 faces away from the side of the touch electrode layer 111 to provide a touch surface for the user to touch.
請參閱圖1至圖3所示，該保護層20係覆蓋該感應基板10之佈線區12，且對應該接合區13之範圍係具有一缺口21。但值得注意的是，在一較佳實施例中，該保護層20亦可完全覆蓋該感應基板10(圖中未示)，並對應該接合區13之範圍係具有該缺口21。Referring to FIGS. 1 to 3, the protective layer 20 covers the wiring region 12 of the sensing substrate 10, and has a notch 21 corresponding to the range of the bonding region 13. It should be noted that, in a preferred embodiment, the protective layer 20 can also completely cover the sensing substrate 10 (not shown), and the notch 21 is included in the range of the bonding region 13.
該第一接地線30係環繞該保護層20設置，且設置於該保護層20背離該感應基板10之一側，並對應位於該佈線區12中。該軟性電路板40係設置於該保護層20背離該感應基板10之一側，且覆蓋部分的第一接地線30及該保護層20之缺口21。該軟性電路板40係具有複數訊號端子41、至少一接地端子42以及一接地導電片43，該複數訊號端子41及該接地端子42係對準該保護層20之缺口21設置，故各訊號端子41可分別透過該保護層20缺口21電性連接該感應基板10接合區13中對應的接點131，且該對接地端子42亦可透過該保護層20缺口21分別電性連接該感應基板10接合區13的一對接地接點132。更具體來講，訊號端子41及接地端子42是經由保護層20的缺口21的位置設計而分別直接或間接地對應電性接觸接點131及接地接點132，以形成電性連接。該軟性電路板40之接地導電片43係設置於該軟性電路板40面向第一接地線30之一側，以電性連接該第一接地線30。換言之，接地導電片43、訊號端子41及接地端子42是設置於軟性電路板40之相同側面。The first grounding wire 30 is disposed around the protective layer 20 and disposed on a side of the protective layer 20 facing away from the sensing substrate 10 and correspondingly located in the wiring region 12. The flexible circuit board 40 is disposed on the side of the protective layer 20 facing away from the sensing substrate 10, and covers the first grounding wire 30 of the portion and the notch 21 of the protective layer 20. The flexible circuit board 40 has a plurality of signal terminals 41, at least one grounding terminal 42 and a grounding conductive strip 43. The plurality of signal terminals 41 and the grounding terminal 42 are disposed opposite to the notch 21 of the protective layer 20, so that each signal terminal The corresponding contact points 131 in the lands of the sensing substrate 10 are electrically connected to the lands of the sensing substrate 10, and the grounding terminals 42 are electrically connected to the sensing substrate 10 through the notches 21 of the protective layer 20, respectively. A pair of ground contacts 132 of the junction region 13. More specifically, the signal terminal 41 and the ground terminal 42 respectively directly or indirectly correspond to the electrical contact contact 131 and the ground contact 132 via the position design of the notch 21 of the protective layer 20 to form an electrical connection. The grounding conductive strip 43 of the flexible circuit board 40 is disposed on one side of the flexible circuit board 40 facing the first grounding line 30 to electrically connect the first grounding wire 30. In other words, the grounding conductive strip 43, the signal terminal 41, and the grounding terminal 42 are disposed on the same side of the flexible circuit board 40.
在本實施例中，該保護層20缺口21中係填充有一異方性導電膠22，用以電性連接該軟性電路板40之複數訊號端子41與該感應基板10接合區13中對應的接點131，以及電性連接該軟性電路板40之該接地端子42與該感應基板10接合區13中該接地接點132。In this embodiment, the notch 21 of the protective layer 20 is filled with an anisotropic conductive adhesive 22 for electrically connecting the plurality of signal terminals 41 of the flexible circuit board 40 and the corresponding contacts in the bonding area 13 of the sensing substrate 10. The grounding terminal 131 is electrically connected to the grounding terminal 42 of the flexible circuit board 40 and the grounding contact 132 in the bonding area 13 of the sensing substrate 10.
在本較佳實施例中，藉由額外設置該第一接地線30，當靜電放電產生時，靜電大都是由該感應基板10及該保護層20周圍進入，此時靜電除了可透過第二接地線122、接地接點132以及該軟性電路板40上的接地端子42所形成的放電路徑來導入一系統接地端(圖中未示)之外，更因本實施例的第一接地線30係對應在佈線區12沿著感應基板10的周圍區域設置，因此靜電會進一步透過該第一接地線30以及該軟性電路板40上的接地導電片43所形成的放電路徑來導入系統接地端。靜電放電時，係由該第一接地線30及該第二接地線122進行放電，藉此來保護內部電路以及該些複數導線121不被靜電擊穿，以達到靜電保護的功能且延長觸控面板的使用壽命，並提高觸控面板的穩定性與可靠性。In the preferred embodiment, by additionally providing the first grounding line 30, when an electrostatic discharge is generated, the static electricity is mostly entered by the sensing substrate 10 and the protective layer 20, and the static electricity is transmitted through the second ground. The discharge path formed by the line 122, the ground contact 132, and the ground terminal 42 on the flexible circuit board 40 is introduced into a system ground terminal (not shown), and the first ground line 30 of the embodiment is further Correspondingly, the wiring region 12 is disposed along the peripheral region of the sensing substrate 10, so that the static electricity is further introduced into the system ground via the discharge path formed by the first grounding wire 30 and the grounding conductive strip 43 on the flexible circuit board 40. During the electrostatic discharge, the first grounding wire 30 and the second grounding wire 122 are discharged, thereby protecting the internal circuit and the plurality of wires 121 from electrostatic breakdown, thereby achieving the function of electrostatic protection and extending the touch. The life of the panel and improve the stability and reliability of the touch panel.
此外，在一較佳實施例中，該第一接地線30的線寬係大於該第二接地線122之線寬，以進一步提高該第一接地線30所能承受的電流，增加靜電排除的效率，提高靜電保護的功能。且該第一接地線30的設置位置係正對於該第二接地線122的設置位置，或者是該第一接地線30的設置位置相較於該第二接地線122的設置位置更為靠近該感應基板10的邊緣，令靜電由該感應基板10及該保護層20周圍進入時，會優先導入該第一接地線30，且因為該第一接地線30相較於該第二接地線122與該些導線121之距離較遠，令靜電優先由該第一接地線30排除，能避免該第二接地線122來不及排除靜電，而導致靜電擊穿其他線路的情況發生。In addition, in a preferred embodiment, the line width of the first ground line 30 is greater than the line width of the second ground line 122 to further increase the current that the first ground line 30 can withstand, and increase the static elimination. Efficiency, improve the function of electrostatic protection. And the first grounding wire 30 is disposed at a position where the second grounding wire 122 is disposed, or the first grounding wire 30 is disposed closer to the second grounding wire 122 than the second grounding wire 122 is disposed. When the edge of the substrate 10 is sensed to allow static electricity to enter from the periphery of the sensing substrate 10 and the protective layer 20, the first ground line 30 is preferentially introduced, and because the first ground line 30 is compared with the second ground line 122 The distance between the wires 121 is far away, so that the static electricity is preferentially removed by the first grounding wire 30, and the second grounding wire 122 can be prevented from being excluded from static electricity, which causes static electricity to break through other wires.
然而，上述描述係透過該第一接地線30與該第二接地線122同時將靜電排除，利用兩個路徑進行放電，故該第一接地線30與該第二接地線122皆為靜電排除之功用，於實際使用與設計上，僅設置有該第一接地線30，而無須額外設置該第二接地線122，即令該靜電防護觸控面板具有排除靜電之功能。However, the above description removes static electricity through the first ground line 30 and the second ground line 122 at the same time, and discharges by using two paths. Therefore, the first ground line 30 and the second ground line 122 are all electrostatically excluded. For the purpose of practical use and design, only the first grounding wire 30 is provided, and the second grounding wire 122 is not required to be additionally provided, so that the static electricity protection touch panel has the function of eliminating static electricity.
值得注意的是，在一較佳實施例中，本發明靜電防護觸控面板第一接地線30的數量亦可以為複數條（圖中未示），且該些第一接地線30係呈間隔排列且彼此相互電性連接，以藉由設置多條第一接地線30來達到更佳的靜電排除功效。It should be noted that, in a preferred embodiment, the number of the first grounding wires 30 of the static electricity protection touch panel of the present invention may also be plural (not shown), and the first grounding wires 30 are spaced apart. Arranged and electrically connected to each other to achieve better electrostatic discharge efficiency by providing a plurality of first ground lines 30.
另外，本發明為了更進一步加強電子裝置靜電防護的能力，該軟性電路板40的接地導電片43與該對接地端子42之總面積相比，係具有較大的面積，故能將更多靜電同時導入該系統接地端，加速靜電的排除，來保護其他線路。In addition, in order to further enhance the electrostatic protection capability of the electronic device, the grounding conductive strip 43 of the flexible circuit board 40 has a larger area than the total area of the pair of grounding terminals 42, so that more static electricity can be used. At the same time, the grounding end of the system is imported to accelerate the elimination of static electricity to protect other lines.
請參閱圖3及圖4所示，本發明靜電防護觸控面板係進一步包含有一絕緣層50。該絕緣層50係覆蓋該第一接地線30，但於對準該軟性電路板40的接地導電片43處的第一接地線30，未被該絕緣層50覆蓋，因此該接地導電片43便可與該第一接地線30電性連接，使該第一接地線30透過該軟性電路板40的接地導電片43電性連接至該系統接地點。該絕緣層50之設置係用以防止該第一接地線30與其他線路或電路接觸，預防靜電擊穿其他線路可能，以加強本發明靜電防護的功能。Referring to FIG. 3 and FIG. 4 , the electrostatic protection touch panel of the present invention further includes an insulating layer 50 . The insulating layer 50 covers the first grounding line 30, but the first grounding wire 30 at the grounding conductive strip 43 of the flexible circuit board 40 is not covered by the insulating layer 50, so the grounding conductive strip 43 is The first grounding wire 30 can be electrically connected to the first grounding wire 30, and the first grounding wire 30 is electrically connected to the grounding point of the system through the grounding conductive strip 43 of the flexible circuit board 40. The insulating layer 50 is disposed to prevent the first grounding wire 30 from coming into contact with other circuits or circuits, and to prevent electrostatic breakdown of other circuits to enhance the electrostatic protection function of the present invention.
而該感應基板10係進一步包含有一遮光層123，該遮光層123係形成於該感應基板10面向該些導線121之一側，且位於該些導線121與該感應基板10之間，並設置於該佈線區12內。該遮光層123之設置係用以遮蔽光線穿透，避免該些導線121與該軟性電路板40被使用者看見而影響觀感。The sensing substrate 10 further includes a light shielding layer 123 formed on one side of the sensing substrate 10 facing the wires 121, and between the wires 121 and the sensing substrate 10, and disposed on the sensing substrate 10 Inside the wiring area 12. The light shielding layer 123 is disposed to shield the light from penetrating, and the wires 121 and the flexible circuit board 40 are prevented from being seen by the user to affect the look and feel.
藉此，本發明第一較佳實施例的靜電防護觸控面板係將該第一接地線30環繞設置於該保護層20背離該感應基板10之一側，因此當該軟性電路板40於覆蓋該保護層20時，係同時透過該保護層20之缺口21將該軟性電路板40之複數訊號端子41及該對接地端子42分別與該感應基板10之接合區13中的複數接點131及接地接點132電性連接，且該軟性電路板40係直接覆蓋部分該第一接地線30以將該接地導電片43與該第一接地線30電性連接，故該軟性電路板40只需增設該接地導電片43並覆蓋於該保護層20，即可輕易地完成本發明，且同時具有兩條接地路徑來排除靜電放電產生的靜電，以能達到更強的靜電防護功能，提高觸控面板的穩定性與使用壽命。Therefore, the electrostatic protection touch panel of the first preferred embodiment of the present invention surrounds the first grounding wire 30 on one side of the protective layer 20 away from the sensing substrate 10, so when the flexible circuit board 40 is covered In the protective layer 20, the plurality of signal terminals 41 of the flexible circuit board 40 and the pair of ground terminals 42 are respectively connected to the plurality of contacts 131 in the bonding region 13 of the sensing substrate 10 through the notch 21 of the protective layer 20. The grounding contact 132 is electrically connected, and the flexible circuit board 40 directly covers a portion of the first grounding wire 30 to electrically connect the grounding conductive strip 43 to the first grounding wire 30. Therefore, the flexible circuit board 40 only needs to be By adding the grounding conductive sheet 43 and covering the protective layer 20, the invention can be easily completed, and at the same time, two grounding paths are provided to eliminate static electricity generated by electrostatic discharge, so as to achieve stronger electrostatic protection function and improve touch. Panel stability and service life.

The flexible circuit board 40 is disposed on one side of the protective layer 20 facing the sensing substrate 10, that is, between the protective layer 20 and the sensing substrate 10, and the grounding conductive sheet 43 of the flexible circuit board 40 is disposed on The flexible circuit board 40 faces one side of the protective layer 20 to electrically connect the first ground line 30 through the notch 21 of the protective layer 20. The signal terminal 41 and the grounding terminal 42 of the flexible circuit board 40 are disposed on one side of the flexible circuit board 40 facing the sensing substrate 10. In other words, the grounding conductive strip 43 of the embodiment is disposed with the signal terminal 41 and the grounding terminal 42. The opposite side of the flexible circuit board 40.

在一較佳實施例中，當第一接地線30的數量為多條時，該保護層20之缺口21的數量亦可對應該些第一接地線30為多個（圖中未示），且該些缺口21係呈間隔式排列，藉此該些第一接地線30可以通過該些缺口21分別與軟性電路板40之接地導電片43電性連接。In a preferred embodiment, when the number of the first grounding wires 30 is plural, the number of the notches 21 of the protective layer 20 may also correspond to a plurality of first grounding wires 30 (not shown). The notches 21 are arranged in a spaced manner, so that the first grounding wires 30 can be electrically connected to the grounding conductive strips 43 of the flexible circuit board 40 through the notches 21, respectively.
