For example, a general touch panel can be applied to a liquid crystal display device. When an electrostatic discharge phenomenon occurs, static electricity may be introduced into the liquid crystal panel through the common electrode (Vcom) of the liquid crystal display device, or even damage the driver IC. Poor display. In addition, the common electrode of the liquid crystal display device is an AC drive, which is more likely to cause noise to affect the touch panel and cause malfunction, so that the user cannot operate accurately, which is a problem worthy of discussion and urgently to be solved.

本實施例提出一種防靜電干擾之觸控式顯示裝置，其包括平行設置之觸控面板與顯示裝置。觸控面板與 顯示裝置之間設置有透明屏蔽層，且在透明屏蔽層週緣設有共地連接之低阻抗材質，使觸控式顯示裝置除了具備顯示、觸控操作外，更提升抑制雜訊及靜電防護效果。 This embodiment provides an anti-static interference touch display device including a touch panel and a display device disposed in parallel. Touch panel and A transparent shielding layer is disposed between the display devices, and a low-impedance material that is commonly connected to the periphery of the transparent shielding layer is provided, so that the touch display device not only has display and touch operations, but also enhances noise suppression and electrostatic protection. .
請參照第1圖，其係依照本發明較佳實施例的一種防靜電干擾之觸控式顯示裝置之示意圖。如第1圖所示，觸控式顯示裝置1包括一觸控面板10、一主動陣列基板12、一透明屏蔽層14與一低阻抗材料層16。主動陣列基板12平行觸控面板10設置，其例如是一薄膜電晶體陣列基板。觸控面板10係為一電容式觸控面板，包含一基板以及設置於其上之觸控元件，其細部結構設計將於之後附圖說明。 Please refer to FIG. 1 , which is a schematic diagram of an anti-static interference touch display device according to a preferred embodiment of the present invention. As shown in FIG. 1 , the touch display device 1 includes a touch panel 10 , an active array substrate 12 , a transparent shielding layer 14 and a low-resistance material layer 16 . The active array substrate 12 is disposed in parallel with the touch panel 10, which is, for example, a thin film transistor array substrate. The touch panel 10 is a capacitive touch panel comprising a substrate and a touch element disposed thereon. The detailed structure design will be described later in the drawings.
透明屏蔽層14整面設置在主動陣列基板12與觸控面板10之間。透明屏蔽層14之材質可與觸控面板10之感測電極(未繪示於第1圖中)材料相同，例如同為氧化銦錫，或是其他透明導電材料，如氧化鎘錫(CTO)、氧化鋅鋁(AZO)、氧化銦鋅(IZO)、氧化鋅(ZnO)、氧化錫(SnO)或前述材料之組合。低阻抗材料層16與透明屏蔽層14共地連接，且沿著透明屏蔽層14之週緣設置，並位在透明屏蔽層14與主動陣列基板12之間。低阻抗材料層16之材質可為金屬，使低阻抗材料層16在透明屏蔽層14之下週緣構成一共地金屬環。 The transparent shielding layer 14 is disposed on the entire surface between the active array substrate 12 and the touch panel 10 . The material of the transparent shielding layer 14 can be the same as that of the sensing electrode (not shown in FIG. 1 ) of the touch panel 10 , for example, indium tin oxide or other transparent conductive materials such as cadmium tin oxide (CTO). Aluminum zinc oxide (AZO), indium zinc oxide (IZO), zinc oxide (ZnO), tin oxide (SnO) or a combination of the foregoing. The low-resistance material layer 16 is commonly connected to the transparent shielding layer 14 and disposed along the periphery of the transparent shielding layer 14 and between the transparent shielding layer 14 and the active array substrate 12. The material of the low-resistance material layer 16 may be a metal such that the low-resistance material layer 16 forms a common metal ring around the periphery of the transparent shielding layer 14.
若僅設置整面由氧化銦錫構成之透明屏蔽層14，其常因阻抗過高而降低了屏蔽之效果，因此，在透明屏蔽層14之下週緣設置金屬材質且共地連接之低阻抗材料層16時，可強化單一透明屏蔽層14之靜電防護能力。此外， 在另一實施例中在透明屏蔽層14上藉由週緣區域阻值小於等於中心區域阻值之設計亦可達到相同之效果。 If only the transparent shielding layer 14 made of indium tin oxide is provided, the shielding effect is often lowered due to the high impedance. Therefore, a low-impedance material which is made of a metal material and is commonly connected to the periphery of the transparent shielding layer 14 is provided. At layer 16, the electrostatic protection capability of the single transparent shield layer 14 can be enhanced. In addition, In another embodiment, the same effect can be achieved on the transparent shielding layer 14 by the design that the peripheral region resistance is less than or equal to the central region resistance.
觸控式顯示裝置1更包括一平坦層18，其整面覆蓋透明屏蔽層14與低阻抗材料層16，以保護這兩層結構，並使結構表面平坦化，更利於其他層結構之設置。 The touch display device 1 further includes a flat layer 18 covering the transparent shielding layer 14 and the low-resistance material layer 16 to protect the two layers and flatten the surface of the structure, which is advantageous for the arrangement of other layer structures.
本實施例之觸控式顯示裝置1可為利用液晶顯示技術之單色顯示裝置或是彩色顯示裝置。較佳地，觸控式顯示裝置1更包括一彩色濾光層20與一液晶層22。彩色濾光層20可設置在觸控面板10與主動陣列基板12之間，而液晶層22則可設置在主動陣列基板12與彩色濾光層20之間。以本實施例之結構而言，較佳地，彩色濾光層20設置在觸控面板10與透明屏蔽層14之間，而液晶層22則設置在平坦層18與主動陣列基板12之間。在本實施例中，彩色濾光層20也可直接與觸控面板10之基材整合在一起，以降低整體結構之厚度。 The touch display device 1 of the present embodiment may be a monochrome display device or a color display device using liquid crystal display technology. Preferably, the touch display device 1 further includes a color filter layer 20 and a liquid crystal layer 22. The color filter layer 20 can be disposed between the touch panel 10 and the active array substrate 12, and the liquid crystal layer 22 can be disposed between the active array substrate 12 and the color filter layer 20. In the structure of the present embodiment, preferably, the color filter layer 20 is disposed between the touch panel 10 and the transparent shielding layer 14, and the liquid crystal layer 22 is disposed between the flat layer 18 and the active array substrate 12. In this embodiment, the color filter layer 20 can also be directly integrated with the substrate of the touch panel 10 to reduce the thickness of the overall structure.
觸控式顯示裝置1更包括一共同電極24，其設置在平坦層18之下表面，並連接主動陣列基板12。由於透明屏蔽層14與低阻抗材料層16位在共同電極24上方，其防止觸控面板10上觸控元件所產生之靜電或外部雜訊透過共同電極24進入主動陣列基板12中，使靜電或外部雜訊無法干擾驅動IC(未繪示)或主動陣列基板12上之電子訊號。另外，觸控式顯示裝置1更包括二個偏光片26、28，其中，偏光片26貼附在觸控面板10上表面，偏光片28則貼附在主動陣列基板12下表面。 The touch display device 1 further includes a common electrode 24 disposed on the lower surface of the flat layer 18 and connected to the active array substrate 12. Since the transparent shielding layer 14 and the low-resistance material layer 16 are located above the common electrode 24, the electrostatic or external noise generated by the touch elements on the touch panel 10 is prevented from entering the active array substrate 12 through the common electrode 24, so that static electricity or External noise cannot interfere with the electronic signals on the driver IC (not shown) or the active array substrate 12. In addition, the touch display device 1 further includes two polarizers 26 and 28, wherein the polarizer 26 is attached to the upper surface of the touch panel 10, and the polarizer 28 is attached to the lower surface of the active array substrate 12.
並請參照第2圖，其係第1圖觸控式顯示裝置 更包括透明覆蓋板(Cover lens)之示意圖。如第2圖所示，透明覆蓋板11設置在偏光片26與彩色濾光層20之間，且係為觸控面板10之基材，材質可為玻璃、壓克力或工程塑膠等具有高強度、耐刮、高透光等特性之材料。 Please refer to FIG. 2, which is a touch display device of FIG. It also includes a schematic diagram of a transparent cover lens. As shown in FIG. 2, the transparent cover plate 11 is disposed between the polarizer 26 and the color filter layer 20, and is a substrate of the touch panel 10, and the material may be high in glass, acrylic or engineering plastics. A material that is characterized by strength, scratch resistance, and high light transmission.
第2圖所示之各層結構實際上可根據裝置設置需求與製程而具有其他不同配置。請參照第3圖，其係第2圖觸控式顯示裝置另一實施態樣之示意圖。如第3圖所示，平坦層18設置在觸控面板10之下表面，低阻抗材料層16與透明屏蔽層14設置在平坦層18之下表面，然後，彩色濾光層20與共同電極24則依序設置在透明屏蔽層14之下表面，其他如液晶層22、主動陣列基板12與偏光片28之位置則不變。由於透明屏蔽層14與低阻抗材料層16依然位在共同電極24與觸控面板10的觸控元件之間，此裝置之結構亦可避免靜電、雜訊干擾的問題。 The layers of the structure shown in Figure 2 can actually have other different configurations depending on the device setup requirements and process. Please refer to FIG. 3 , which is a schematic diagram of another embodiment of the touch display device of FIG. 2 . As shown in FIG. 3, the flat layer 18 is disposed on the lower surface of the touch panel 10, and the low-resistance material layer 16 and the transparent shielding layer 14 are disposed on the lower surface of the flat layer 18. Then, the color filter layer 20 and the common electrode 24 are provided. Then, the lower surface of the transparent shielding layer 14 is sequentially disposed, and the positions of the other liquid crystal layer 22, the active array substrate 12, and the polarizer 28 are unchanged. Since the transparent shielding layer 14 and the low-resistance material layer 16 are still located between the common electrode 24 and the touch element of the touch panel 10, the structure of the device can also avoid the problem of static electricity and noise interference.
以下針對本實施例之觸控面板10作進一步的說明。本實施例之觸控面板10實質上可為單層基材或雙層基材之結構設計，將分別以圖式說明之。 The touch panel 10 of the present embodiment will be further described below. The touch panel 10 of the present embodiment can be substantially a single-layer substrate or a two-layer substrate, and will be described in the drawings.
請參照第4圖，其係觸控面板的觸控元件之示意圖。如第4圖所示，觸控元件包括多個第一感測電極110與多個第二感測電極120。第一感測電極110相互平行且等間隔，並各自沿著第一方向(如圖式之Y方向)延伸。第二感測電極120相互平行且等間隔設置，並各自沿著垂直第一方向之第二方向(如圖式之X方向)延伸。各個第一感測電極110包括多個相連之第一電極區塊112，第二感測電極120包括多個相連之第二電極區塊122。第一電極區塊112 與第二電極區塊122可為任意形狀，如正方形、長方形、菱形、三角形、多邊形、圓形、橢圓形等，本實施例係以菱形之電極區塊為例。 Please refer to FIG. 4 , which is a schematic diagram of a touch component of a touch panel. As shown in FIG. 4 , the touch element includes a plurality of first sensing electrodes 110 and a plurality of second sensing electrodes 120 . The first sensing electrodes 110 are parallel to each other and equally spaced, and each extend in a first direction (in the Y direction as shown). The second sensing electrodes 120 are disposed parallel to each other and equally spaced, and each extend in a second direction perpendicular to the first direction (in the X direction of the drawing). Each of the first sensing electrodes 110 includes a plurality of connected first electrode blocks 112, and the second sensing electrodes 120 include a plurality of connected second electrode blocks 122. First electrode block 112 The second electrode block 122 may have any shape, such as a square, a rectangle, a diamond, a triangle, a polygon, a circle, an ellipse, etc., and the embodiment is a diamond-shaped electrode block.
如第4圖所示，第一電極區塊112與第二電極區塊122係交錯配置，以在定義單一位置之X與Y座標。當第一感測電極110與第二感測電極120設置在單層基材上時(如第1圖及第3圖所示)，可設置絕緣材料於二者之交會點C，使其中一感測電極跨接在另一感測電極上，以避免第一感測電極110與第二感測電極120短路。另外，第一感測電極110與第二感測電極120亦可設置在雙層基材上(如第2圖所示)，此種設計即無須考量交會點C之短路問題。以下舉數例說明觸控面板10之結構設計。 As shown in FIG. 4, the first electrode block 112 and the second electrode block 122 are alternately arranged to define X and Y coordinates of a single position. When the first sensing electrode 110 and the second sensing electrode 120 are disposed on a single-layer substrate (as shown in FIGS. 1 and 3), an insulating material may be disposed at the intersection point C of the two, such that one of them The sensing electrode is connected across the other sensing electrode to prevent the first sensing electrode 110 from being short-circuited with the second sensing electrode 120. In addition, the first sensing electrode 110 and the second sensing electrode 120 may also be disposed on the two-layer substrate (as shown in FIG. 2), and the design does not need to consider the short-circuit problem of the intersection point C. The following is a description of the structural design of the touch panel 10.
以第4圖中交會點C之剖面說明觸控面板10之各層結構。請參照第5A圖，其係觸控面板之第一種單層基材設計之示意圖。第一感測電極110與第二感測電極120設置在同一基材130上。如第5A圖所示，第一感測電極110上覆蓋有絕緣層116，第一感測電極110兩旁之第二電極區塊122則透過設置在絕緣層116上之導線124跨接在第一感測電極110上以構成一島型橋接(bridge island)之結構，如此一來，不僅可使第二感測電極120之所有第二電極區塊122連接起來，同時也避免了短路的問題。 The structure of each layer of the touch panel 10 will be described with a cross section of the intersection point C in FIG. Please refer to FIG. 5A, which is a schematic diagram of the first single layer substrate design of the touch panel. The first sensing electrode 110 and the second sensing electrode 120 are disposed on the same substrate 130. As shown in FIG. 5A, the first sensing electrode 110 is covered with an insulating layer 116, and the second electrode block 122 on both sides of the first sensing electrode 110 is connected to the first through the wire 124 disposed on the insulating layer 116. The sensing electrode 110 is configured to form a bridge island structure, so that not only all of the second electrode blocks 122 of the second sensing electrode 120 can be connected, but also the problem of short circuit is avoided.
另外，第二電極區塊122更可透過其他導線126連接至外部電路板，例如是軟性電路板128。導線124、126之材質可為金屬或是透明導電材料，如氧化銦錫。最後，再以一保護層118覆蓋住第一感測電極110、第二感測電極 120與導線124、126等結構。具靜電防護功能之透明屏蔽層14則可設置在基材130上相反於第一感測電極110與第二感測電極120之側面，例如是基材130之下表面。第1圖之彩色濾光層20可設置在基材130與透明屏蔽層14之間，或是直接與基材130整合在一起。第1圖之低阻抗材料層16、平坦層18、共同電極24、液晶層22與主動陣列基板12等元件則是設置在透明屏蔽層14之下方。 In addition, the second electrode block 122 is further connected to an external circuit board through other wires 126, such as a flexible circuit board 128. The wires 124, 126 may be made of metal or a transparent conductive material such as indium tin oxide. Finally, the first sensing electrode 110 and the second sensing electrode are covered by a protective layer 118. 120 and wires 124, 126 and the like. The transparent shielding layer 14 with electrostatic protection function may be disposed on the substrate 130 opposite to the side of the first sensing electrode 110 and the second sensing electrode 120, for example, the lower surface of the substrate 130. The color filter layer 20 of FIG. 1 may be disposed between the substrate 130 and the transparent shielding layer 14 or directly integrated with the substrate 130. Elements such as the low-resistance material layer 16, the flat layer 18, the common electrode 24, the liquid crystal layer 22, and the active array substrate 12 of FIG. 1 are disposed under the transparent shielding layer 14.
請參照第5B、5C圖，其係觸控面板之第二、三種單層基材設計之示意圖。絕緣層116整面覆蓋在第一感測電極110與第二感測電極120上，並具有多個接觸孔116a。這些接觸孔116a暴露第二電極區塊122之局部表面，導線124延伸至接觸孔116a中，並連接第二電極區塊122，其中，導線124僅局部填充接觸孔116a(見第5B圖)，或是完全填滿接觸孔116a(見第5C圖)。保護層118則覆蓋第一感測電極110、第二感測電極120與導線124等結構。 Please refer to FIG. 5B and FIG. 5C , which are schematic diagrams of the second and three single-layer substrate designs of the touch panel. The insulating layer 116 covers the first sensing electrode 110 and the second sensing electrode 120 over the entire surface and has a plurality of contact holes 116a. The contact holes 116a expose a partial surface of the second electrode block 122, and the wires 124 extend into the contact holes 116a and are connected to the second electrode block 122, wherein the wires 124 only partially fill the contact holes 116a (see FIG. 5B). Or completely fill the contact hole 116a (see Figure 5C). The protective layer 118 covers the structures of the first sensing electrode 110, the second sensing electrode 120, and the wires 124.
請參照第6A、6B圖，其係觸控面板之第四、五種單層基材設計之示意圖。導線124除了以上述島型橋接與接觸孔之方式連接電極區塊外，亦可設置以其他方式連接電極區塊。如第6A圖所示，導線124被埋設在基材130上，其中，導線124是直接設置在基材130上，再以絕緣層116局部覆蓋住導線124。第一感測電極110設置在絕緣層116上，透過絕緣層116以與導線124分隔開來。第二感測電極120局部設置在絕緣層116上，其第二電極區塊122連接到導線124未被絕緣層116覆蓋的部分，藉此使第二感測電極120之所有第二電極區塊122連接起來。最後再以保護層118 覆蓋住第一感測電極110、第二感測電極120等結構。 Please refer to FIGS. 6A and 6B , which are schematic diagrams of the fourth and fifth single-layer substrate designs of the touch panel. In addition to the above-described island-type bridging and contact holes, the wires 124 may be connected to the electrode blocks in other manners. As shown in FIG. 6A, the wires 124 are embedded on the substrate 130, wherein the wires 124 are disposed directly on the substrate 130, and the wires 124 are partially covered by the insulating layer 116. The first sensing electrode 110 is disposed on the insulating layer 116 and is separated from the wire 124 by the insulating layer 116. The second sensing electrode 120 is partially disposed on the insulating layer 116, and the second electrode block 122 is connected to a portion of the wire 124 that is not covered by the insulating layer 116, thereby making all the second electrode blocks of the second sensing electrode 120 122 connected. Finally, with protective layer 118 The first sensing electrode 110, the second sensing electrode 120, and the like are covered.
如第6B圖所示，絕緣層116更可整面覆蓋住導線124與基材130。絕緣層116具有接觸孔116a，其中，接觸孔116a暴露導線124之局部表面。第一感測電極110兩側之第二電極區塊122延伸至接觸孔116a中，並連接導線124，如此可使第二感測電極120之所有第二電極區塊122全數串連起來。 As shown in FIG. 6B, the insulating layer 116 covers the wire 124 and the substrate 130 over the entire surface. The insulating layer 116 has a contact hole 116a in which the contact hole 116a exposes a partial surface of the wire 124. The second electrode block 122 on both sides of the first sensing electrode 110 extends into the contact hole 116a and is connected to the wire 124. Thus, all the second electrode blocks 122 of the second sensing electrode 120 can be connected in series.

As shown in FIG. 5A, the first sensing electrode 110 and the second sensing electrode 120 are disposed opposite to each other between the first substrate 210 and the second substrate 220, that is, the first sensing electrode 110 and the first The electrode patterns of the two sensing electrodes 120 are disposed face to face, and the transparent shielding layer 14 is disposed on the outer side of the first substrate 210 (or the second substrate 220). The touch panel 10 further has a spacer 230 for maintaining a distance between the first substrate 210 and the second substrate 220. A layer of optical glue 240 may be coated between the first substrate 210 and the second substrate 220 to fix the two substrates.
如第7B圖所示，第一感測電極110與第二感測電極120是同向設置，例如，第一感測電極110設置在第一基材210之下表面，而第二感測電極120設置在第二基材220之下表面，並位在第一基材210與第二基材220之間。由於第一感測電極110位在第一基材210之外側，較佳地，以一絕緣層250整面覆蓋並保護第一感測電極110。透明屏 蔽層14可與第一感測電極110設置在第一基材210之同側，並直接以絕緣層250將二者分隔開來。 As shown in FIG. 7B, the first sensing electrode 110 and the second sensing electrode 120 are disposed in the same direction. For example, the first sensing electrode 110 is disposed on the lower surface of the first substrate 210, and the second sensing electrode is disposed. The 120 is disposed on the lower surface of the second substrate 220 and is positioned between the first substrate 210 and the second substrate 220. Since the first sensing electrode 110 is located on the outer side of the first substrate 210, preferably, the first sensing electrode 110 is covered and protected by an insulating layer 250. Transparent screen The mask 14 may be disposed on the same side of the first substrate 210 as the first sensing electrode 110 and directly separate the two by the insulating layer 250.
