近年來，隨著資訊技術、無線行動通訊和資訊家電的快速發展與應用，為了達到更便利、體積更輕巧化以及更人性化的目的，許多電子資訊產品，例如是行動電話(Mobile Phone)、掌上型電腦(Handheld PC)、個人化數位助理(Personal Digital Assistance，PDA)或是智慧型手機(Smart Phone)等，其輸入方式已由傳統的鍵盤或滑鼠等裝置，轉變為使用觸控面板(Touch Panel)作為輸入裝置。由於便利性與操作的直覺性，觸控面板成為極受歡迎的新型態人機介面與多媒體互動方式，而受到相當的重視與大量開發，其中觸控顯示面板更為現今最流行的產品。In recent years, with the rapid development and application of information technology, wireless mobile communication and information appliances, many electronic information products, such as mobile phones, are used for the purpose of being more convenient, lighter and more humanized. Handheld PC, Personal Digital Assistance (PDA) or Smart Phone, the input method has been changed from a traditional keyboard or mouse to a touch panel. (Touch Panel) as an input device. Due to the convenience and intuitive operation, the touch panel has become a very popular new type of human interface and multimedia interaction, and has received considerable attention and extensive development. Among them, the touch display panel is the most popular product.
觸控面板依照其結構及製造方式的不同，大致上可區分為整合式(On-Cell)、內建式(In-Cell)及外貼式(Added-on)，其中整合式及內建式觸控面板是將觸控功能整合於面板生產製程，有助於縮小整體產品的厚度，以符合產品輕薄化的趨勢，而外貼式觸控面板是將觸控面板與顯示面板分開製作後再進行貼附，以簡化單一製程的步驟。Touch panels can be roughly classified into On-Cell, In-Cell, and Added-on depending on their structure and manufacturing method. Integrated and built-in The touch panel integrates the touch function into the panel manufacturing process, which helps to reduce the thickness of the overall product to meet the trend of thinning and thinning. The external touch panel is separately made from the touch panel and the display panel. Attachment to simplify the process of a single process.
使用者可利用觸控工具例如觸控筆輕點觸控面板，或直接利用手指觸碰觸控面板，以進行觸控顯示面板的操作，而操作結果可透過顯示面板顯現。當使用者操作觸控顯示面板時，觸控工具或是使用者的手指會與觸控面板發生摩擦，因而在觸控面板上產生靜電放電(Electrostatic Discharge Current，ESD)。由於靜電放電電壓比一般所提供之電源的電壓大出許多，當靜電放電發生在觸控面板上的特定區域時，此靜電放電的電流可能會將觸控面板上的元件燒毀，而導致觸控面板的功能受到影響甚至產生損毀。The user can use a touch tool such as a stylus to tap the touch panel, or directly touch the touch panel with a finger to perform the operation of the touch display panel, and the operation result can be displayed through the display panel. When the user operates the touch display panel, the touch tool or the user's finger may rub against the touch panel, thereby generating an Electrostatic Discharge Current (ESD) on the touch panel. Since the electrostatic discharge voltage is much larger than the voltage of the power supply generally provided, when the electrostatic discharge occurs in a specific area on the touch panel, the current of the electrostatic discharge may burn the components on the touch panel, resulting in touch. The function of the panel is affected or even destroyed.

In the embodiment, the touch display panel 100 includes a display panel 110 , a touch panel 120 , a circuit board 130 , a first flexible circuit board 140 , and a second flexible circuit board 150 . In order to make the drawings clearer, FIG. 1 shows the display panel 110 separately from the touch panel 120. In the embodiment, the touch panel 120 is located on one side of the display panel 110 and is attached to the display panel 110 . The circuit board 130 is disposed between the display panel 110 and the touch panel 120.
詳細而言，請參考圖1與圖2。圖2是圖1之觸控顯示面板於顯示面板處的示意圖。在本實施例中，顯示面板110具有顯示區R1以及非顯示區R2。顯示面板110之顯示區R1中具有多個畫素結構114以及與畫素結構114電性連接的多條訊號線116，如圖2所示，而顯示面板110可藉由這些畫素結構114與這些訊號線116顯示影像。在本實施例，上述之訊號線116包括掃描線以及資料線，且每一個畫素結構114與對應的一條掃描線以及對應的一條資料線電性連接。此外，畫素結構114包括主動元件T以及與主動元件T電性連接的畫素電極PE，而上述之訊號線116自顯示區R1延伸至非顯示區域R2中以與驅動裝置DR電性連接。In detail, please refer to FIG. 1 and FIG. 2. 2 is a schematic view of the touch display panel of FIG. 1 at a display panel. In the present embodiment, the display panel 110 has a display area R1 and a non-display area R2. The display area R1 of the display panel 110 has a plurality of pixel structures 114 and a plurality of signal lines 116 electrically connected to the pixel structure 114, as shown in FIG. 2, and the display panel 110 can be connected to the pixel structure 114 by These signal lines 116 display images. In this embodiment, the signal line 116 includes a scan line and a data line, and each pixel structure 114 is electrically connected to a corresponding one of the scan lines and a corresponding one of the data lines. In addition, the pixel structure 114 includes an active device T and a pixel electrode PE electrically connected to the active device T, and the signal line 116 extends from the display region R1 into the non-display region R2 to be electrically connected to the driving device DR.
在本實施例中，顯示面板110之非顯示區R2中具有共用電壓線112。共用電壓線112圍繞於顯示區R1的周圍。所述共用電壓線112可提供顯示區R1中的畫素結構114所需的共用電壓。舉例來說，畫素結構114中的電容電極線可以電性連接所述共用電壓線112，以使共用電壓線112上的電壓可以傳遞至各畫素結構114之電容電極線。In the present embodiment, the non-display area R2 of the display panel 110 has a common voltage line 112. The common voltage line 112 surrounds the periphery of the display area R1. The common voltage line 112 can provide a common voltage required for the pixel structure 114 in the display region R1. For example, the capacitor electrode lines in the pixel structure 114 can be electrically connected to the common voltage line 112 such that the voltage on the common voltage line 112 can be transmitted to the capacitor electrode lines of the respective pixel structures 114.
此外，在本實施例中，顯示面板110之非顯示區R2中具有驅動裝置DR、多個第一接墊電極160以及至少一個第二接墊電極170。驅動裝置DR與訊號線116電性連接，第一接墊電極160與驅動裝置DR電性連接，第二接墊電極170與共用電壓線112電性連接。上述之第一接墊電極160以及第二接墊電極170與第一軟性電路板150電性連接(如圖1所示)。In addition, in the embodiment, the non-display area R2 of the display panel 110 has a driving device DR, a plurality of first pad electrodes 160, and at least one second pad electrode 170. The driving device DR is electrically connected to the signal line 116. The first pad electrode 160 is electrically connected to the driving device DR, and the second pad electrode 170 is electrically connected to the common voltage line 112. The first pad electrode 160 and the second pad electrode 170 are electrically connected to the first flexible circuit board 150 (as shown in FIG. 1).
另一方面，請參考圖1，觸控面板120具有觸控區R3以及非觸控區R4。觸控面板120之觸控區R3中具有觸控元件層(未繪示)，上述觸控元件層可包括由電容式觸控元件或是電阻式觸控元件。上述之觸控元件層與多條訊號線124以及對應的接墊電極126電性連接，以使觸控元件層的觸控訊號可以傳出。此外，上述之接墊電極126與第一軟性電路板140電性連接。根據本實施例，所述觸控面板120更包括控制裝置C，其電性連接於觸控面板120與該第一軟性電路板140之間。換言之，當使用者觸碰觸控面板120以使觸控元件層產生感應時，觸控訊號即可透過訊號線124以及接墊電極126而傳遞至控制裝置C，以計算出觸控位置。On the other hand, referring to FIG. 1 , the touch panel 120 has a touch area R3 and a non-touch area R4. The touch panel R3 of the touch panel 120 has a touch component layer (not shown), and the touch component layer may include a capacitive touch component or a resistive touch component. The touch element layer is electrically connected to the plurality of signal lines 124 and the corresponding pad electrodes 126 so that the touch signals of the touch element layer can be transmitted. In addition, the pad electrode 126 is electrically connected to the first flexible circuit board 140. According to the embodiment, the touch panel 120 further includes a control device C electrically connected between the touch panel 120 and the first flexible circuit board 140. In other words, when the user touches the touch panel 120 to cause the touch element layer to sense, the touch signal can be transmitted to the control device C through the signal line 124 and the pad electrode 126 to calculate the touch position.
另外，觸控面板120之非觸控區R4中具有靜電防護環122。靜電防護環122圍繞於觸控區R3的周圍。當觸控面板120產生靜電放電電流E時，靜電放電電流E可導通至靜電防護環122上，以避免靜電放電電流E對觸控面板120內的元件造成損壞。In addition, the non-touch area R4 of the touch panel 120 has an electrostatic protection ring 122 therein. The electrostatic protection ring 122 surrounds the periphery of the touch area R3. When the touch panel 120 generates the electrostatic discharge current E, the electrostatic discharge current E can be conducted to the static electricity protection ring 122 to prevent the electrostatic discharge current E from damaging the components in the touch panel 120.
承上所述，第一軟性電路板140連接於觸控面板120與電路板130之間，而第二軟性電路板150連接於電路板130與顯示面板110之間。因此，當觸控面板120上產生靜電放電電流E時，靜電防護環122上的靜電放電電流E可經由第一軟性電路板140而傳導至電路板130，再經由第二軟性電路板150而疏通至顯示面板110，以避免靜電放電電流E聚集而對觸控面板120造成破壞。更詳細的說明是，靜電防護環122上的靜電放電電流E經第一軟性電路板140、控制裝置C而傳導至電路板130，再經由第二軟性電路板150與第二接墊電極170而疏通至顯示面板110的共用電壓線112上。As described above, the first flexible circuit board 140 is connected between the touch panel 120 and the circuit board 130, and the second flexible circuit board 150 is connected between the circuit board 130 and the display panel 110. Therefore, when the electrostatic discharge current E is generated on the touch panel 120, the electrostatic discharge current E on the static protection ring 122 can be transmitted to the circuit board 130 via the first flexible circuit board 140, and then cleared through the second flexible circuit board 150. To the display panel 110, the electrostatic discharge current E is concentrated to cause damage to the touch panel 120. In more detail, the electrostatic discharge current E on the static protection ring 122 is transmitted to the circuit board 130 via the first flexible circuit board 140 and the control device C, and then through the second flexible circuit board 150 and the second pad electrode 170. The common voltage line 112 of the display panel 110 is unblocked.
由於觸控面板120上的靜電放電電流E可透過靜電防護環122、第一軟性電路板140而傳導至電路板130，再經由第二軟性電路板150而傳導至第二接墊電極170，因此可使得靜電放電電流E可經由第二接墊電極170而疏通至顯示面板110之共用電壓線112上，以避免靜電放電電流E聚集而對觸控面板120造成破壞。The electrostatic discharge current E on the touch panel 120 can be transmitted to the circuit board 130 through the static protection ring 122 and the first flexible circuit board 140, and then transmitted to the second pad electrode 170 via the second flexible circuit board 150. The electrostatic discharge current E can be unblocked to the common voltage line 112 of the display panel 110 via the second pad electrode 170 to prevent the electrostatic discharge current E from collecting and causing damage to the touch panel 120.
圖3是本發明另一實施例之觸控顯示面板於顯示面板處的示意圖。請參考圖3，在本發明另一實施例中，顯示面板110具有開關元件180。開關元件180電性連接於第二接墊電極170與共用電壓線112之間。在本實施例中，開關元件180為電晶體(Transistor)元件，但在本發明其他實施例中，開關元件180可為二極體(Diode)元件或其他適當的元件，本發明不以此為限制。開關元件180可設定啟動開關的臨界電流量。將開關元件180設置於第二接墊電極170與共用電壓線112之間，可控制靜電放電電流E是否經由第二接墊電極170而疏通至共用電壓線112。FIG. 3 is a schematic diagram of a touch display panel at a display panel according to another embodiment of the present invention. Referring to FIG. 3, in another embodiment of the present invention, the display panel 110 has a switching element 180. The switching element 180 is electrically connected between the second pad electrode 170 and the common voltage line 112. In this embodiment, the switching element 180 is a transistor element, but in other embodiments of the invention, the switching element 180 can be a diode element or other suitable element, and the present invention does not limit. Switching element 180 can set the amount of critical current to activate the switch. The switching element 180 is disposed between the second pad electrode 170 and the common voltage line 112 to control whether the electrostatic discharge current E is unblocked to the common voltage line 112 via the second pad electrode 170.
換言之，當觸控面板120上的靜電放電電流E傳導至第二接墊電極170時，若靜電放電電流E的電流量小於開關元件180的臨界電流量而無法啟動開關元件180，則靜電放電電流E不能通過開關元件180。相對地，當觸控面板120上的靜電放電電流E傳導至第二接墊電極170時，若靜電放電電流E的電流量大於開關元件180的臨界電流量而啟動開關元件180，則靜電放電電流E通過開關元件180而疏通至共用電壓線112。In other words, when the electrostatic discharge current E on the touch panel 120 is conducted to the second pad electrode 170, if the current amount of the electrostatic discharge current E is less than the critical current amount of the switching element 180 and the switching element 180 cannot be activated, the electrostatic discharge current E cannot pass through the switching element 180. In contrast, when the electrostatic discharge current E on the touch panel 120 is conducted to the second pad electrode 170, if the current amount of the electrostatic discharge current E is greater than the critical current amount of the switching element 180 to activate the switching element 180, the electrostatic discharge current E is bypassed to the common voltage line 112 by the switching element 180.
因此，靜電放電電流E啟動開關元件180的臨界電流量，可設定為不超過會對觸控面板120造成破壞的電流量，使得靜電放電電流E在電流量大到足以破壞觸控面板120之前，即可從觸控面板120疏通至顯示面板110的共用電壓線112上。Therefore, the electrostatic discharge current E starts the critical current amount of the switching element 180, and can be set to not exceed the amount of current that causes damage to the touch panel 120, so that the electrostatic discharge current E is large enough to damage the touch panel 120 before the amount of current is large enough to damage the touch panel 120. The touch panel 120 can be unblocked to the common voltage line 112 of the display panel 110.
據此，觸控面板120上的靜電放電電流E可經由靜電防護環122、第一軟性電路板140、控制裝置C而傳導至電路板130，再經由第二軟性電路板150與第二接墊電極170而傳導至開關元件180。若開關元件180被啟動，則靜電放電電流E可疏通至顯示面板110上的共用電壓線112，以避免靜電放電電流E聚集而對觸控面板120造成破壞。Accordingly, the electrostatic discharge current E on the touch panel 120 can be transmitted to the circuit board 130 via the static protection ring 122, the first flexible circuit board 140, and the control device C, and then through the second flexible circuit board 150 and the second pad. The electrode 170 is conducted to the switching element 180. If the switching element 180 is activated, the electrostatic discharge current E can be unblocked to the common voltage line 112 on the display panel 110 to prevent the electrostatic discharge current E from collecting and causing damage to the touch panel 120.
另一方面，在本發明其他實施例中，顯示面板110可僅具有一個開關元件180或具有多個開關元件180，而開關元件180電性連接於第二接墊電極170與共用電壓線112之間。藉由調整開關元件180的數量，可設定靜電放電電流E疏通至共用電壓線112的臨界電流量。然而，在本發明其他實施例中，顯示面板110亦可不設置開關元件180，使得觸控面板120上產生的靜電放電電流E可隨時經由第二接墊電極170疏通至共用電壓線112。本發明不限定開關元件180的數量與設置與否。On the other hand, in other embodiments of the present invention, the display panel 110 may have only one switching element 180 or multiple switching elements 180, and the switching element 180 is electrically connected to the second pad electrode 170 and the common voltage line 112. between. By adjusting the number of switching elements 180, the amount of critical current that the electrostatic discharge current E is unblocked to the common voltage line 112 can be set. However, in other embodiments of the present invention, the display panel 110 may not be provided with the switching element 180, so that the electrostatic discharge current E generated on the touch panel 120 can be unblocked to the common voltage line 112 via the second pad electrode 170 at any time. The present invention does not limit the number and setting of the switching elements 180.
綜上所述，本發明提出一種觸控顯示面板，其觸控面板、第一軟性電路板、電路板、第二軟性電路板以及顯示面板依序電性連接。觸控面板上具有靜電防護環，顯示面板上具有共用電壓線，且共用電壓線與顯示面板上的第二接墊電極電性連接。因此，觸控面板上所產生的靜電放電電流可先聚集至靜電防護環，並經由第一軟性電路板而傳導至電路板，再傳導至第二軟性電路板並經由第二接墊電極而疏通至顯示面板的共用電壓線。據此，觸控顯示面板具有疏通靜電放電電流的功能，以避免靜電放電電流對觸控面板造成破壞。In summary, the present invention provides a touch display panel in which the touch panel, the first flexible circuit board, the circuit board, the second flexible circuit board, and the display panel are electrically connected in sequence. The touch panel has an electrostatic protection ring. The display panel has a common voltage line, and the common voltage line is electrically connected to the second pad electrode on the display panel. Therefore, the electrostatic discharge current generated on the touch panel can be collected to the static protection ring and transmitted to the circuit board via the first flexible circuit board, and then transmitted to the second flexible circuit board and cleared through the second pad electrode. The common voltage line to the display panel. Accordingly, the touch display panel has the function of unblocking the electrostatic discharge current to prevent the electrostatic discharge current from causing damage to the touch panel.
