The lower surface of the substrate of the touch panel has a shielding layer and a plurality of conductive connection points distributed around the periphery of the shielding layer, and the conductive connection points are used for electrically connecting the shielding layer to the conductive ring.
由於本發明實施例的觸控面板之導電圈設置於裝飾層的下面,無需額外佔用觸控面板之周邊區域的面積,因此易於實現窄邊框之電子產品的設計要求。Since the conductive ring of the touch panel of the embodiment of the present invention is disposed under the decorative layer, the area of the peripheral area of the touch panel is not required to be occupied, so that the design requirements of the electronic product of the narrow frame are easily realized.
請參考圖2A、圖2B與圖3,圖2A是本發明實施例的觸控面板之俯視圖,圖2B是本發明實施例的觸控面板之仰視圖,圖3是本發明實施例的觸控面板之剖面圖。觸控面板 5包括保護外殼51、裝飾層52、導電圈53、屏蔽層54、導電連接點55、基板56與觸控感測層57。保護外殼51的表面區分有周邊區域50,周邊區域50位於保護外殼51的周邊且形成邊框。裝飾層52設置於保護外殼51的下面,且位於該周邊區域50。導電圈53設置於裝飾層52的下面,其為環狀結構,且亦位於周邊區域50,以被裝飾層52遮蔽。觸控感測層57設置於基板56的上表面。屏蔽層54設置於基板56的下表面。導電連接點55設置於屏蔽層54之周邊,且用以將屏蔽層54電性連接導電圈53。由於觸控面板5之導電圈53設置於裝飾層52的下面,無需額外佔用觸控面板5的周邊區域50之面積,故易於實現窄邊框之電子產品的設計要求。2A, FIG. 2B and FIG. 3, FIG. 2A is a top view of the touch panel according to the embodiment of the present invention, FIG. 2B is a bottom view of the touch panel according to the embodiment of the present invention, and FIG. 3 is a touch view of the embodiment of the present invention. A sectional view of the panel. Touch panel 5 includes a protective casing 51, a decorative layer 52, a conductive ring 53, a shielding layer 54, a conductive connection point 55, a substrate 56, and a touch sensing layer 57. The surface of the protective casing 51 is distinguished by a peripheral region 50 which is located at the periphery of the protective casing 51 and which forms a frame. The decorative layer 52 is disposed under the protective casing 51 and located at the peripheral region 50. The conductive ring 53 is disposed under the decorative layer 52, which is an annular structure, and is also located in the peripheral region 50 to be shielded by the decorative layer 52. The touch sensing layer 57 is disposed on the upper surface of the substrate 56. The shield layer 54 is disposed on the lower surface of the substrate 56. The conductive connection point 55 is disposed at the periphery of the shielding layer 54 and is used to electrically connect the shielding layer 54 to the conductive ring 53. Since the conductive ring 53 of the touch panel 5 is disposed under the decorative layer 52, it is not necessary to additionally occupy the area of the peripheral region 50 of the touch panel 5, so that the design requirements of the electronic product of the narrow frame are easily realized.
另外,保護外殼51為透明絕緣板材,例如玻璃或透明塑膠板。導電圈53可以為銀膠或導電膠帶。屏蔽層54例如為由透明導電材質所形成的網狀結構或平面結構,多個導電連接點55設置於屏蔽層54之周邊,例如四個角落處,且跨設於基板56的側面,藉以電性連接基板56下表面的屏蔽層54與基板56上表面的導電圈53。另外,導電圈53可以電性連接可撓性印刷電路(未繪於圖2A、圖2B與圖3中)的屏蔽接腳。如此,觸控面板5周圍的干擾雜訊將可以分別被導電圈53與屏蔽層54所吸收,並且透過可撓性印刷電路的屏蔽接腳釋放干擾雜訊至大地。由於導電圈53一般藉由低阻抗的材質製作,且透過導電連接點55電性連接屏蔽層54,因此屏蔽層54具有較均勻且較低之阻抗值,且其各點不會因為與可撓性印刷電路距離不同而具有不同的屏蔽效果。In addition, the protective casing 51 is a transparent insulating plate such as glass or a transparent plastic plate. The conductive ring 53 may be silver glue or conductive tape. The shielding layer 54 is, for example, a mesh structure or a planar structure formed of a transparent conductive material. The plurality of conductive connection points 55 are disposed at the periphery of the shielding layer 54, for example, at four corners, and are disposed across the side of the substrate 56, thereby The shielding layer 54 on the lower surface of the substrate 56 and the conductive ring 53 on the upper surface of the substrate 56 are connected. In addition, the conductive ring 53 can be electrically connected to the shield pins of the flexible printed circuit (not shown in FIGS. 2A, 2B and 3). In this way, the interference noise around the touch panel 5 can be absorbed by the conductive ring 53 and the shielding layer 54, respectively, and the interference noise is transmitted to the ground through the shielding pin of the flexible printed circuit. Since the conductive ring 53 is generally made of a low-impedance material and electrically connected to the shielding layer 54 through the conductive connection point 55, the shielding layer 54 has a relatively uniform and low impedance value, and its points are not flexible and flexible. The printed circuit has different shielding distances due to different distances.
除此之外,觸控面板5更可以包括多個周邊線路59與絕 緣層58。多個周邊線路59設置於基板56之上表面,且電性連接觸控感測層57與可撓性印刷電路的多個信號接腳。多個周邊線路59還位於裝飾層52之下,以被裝飾層52遮蔽。絕緣層58位於周邊線路59與導電圈53之間,以使周邊線路59電性絕緣於導電圈53。絕緣層58可以為黏接層,例如光學膠,雙面膠或UV(ultraviolet)光固膠等,基板56可以透過黏接層與保護外殼51貼合。於本實施例中,絕緣層58為一整層的結構,覆蓋於周邊線路59與觸控感測層57之上,但於另一實施例中,絕緣層58可以為一環狀結構,其僅覆蓋於多個周邊線路59之上,以使周邊線路59電性絕緣於導電圈53即可。In addition, the touch panel 5 can further include a plurality of peripheral lines 59 and Edge layer 58. A plurality of peripheral lines 59 are disposed on the upper surface of the substrate 56 and electrically connected to the touch sensing layer 57 and the plurality of signal pins of the flexible printed circuit. A plurality of perimeter lines 59 are also located below the decorative layer 52 to be obscured by the decorative layer 52. The insulating layer 58 is located between the peripheral line 59 and the conductive ring 53 to electrically insulate the peripheral line 59 from the conductive ring 53. The insulating layer 58 may be an adhesive layer, such as an optical glue, a double-sided tape or an ultraviolet (UV) adhesive, and the substrate 56 may be adhered to the protective casing 51 through the adhesive layer. In this embodiment, the insulating layer 58 is a one-layer structure covering the peripheral line 59 and the touch sensing layer 57. However, in another embodiment, the insulating layer 58 may be a ring structure. It is only covered over the plurality of peripheral lines 59 to electrically insulate the peripheral lines 59 from the conductive rings 53.

請接著參照圖5,圖5是本發明實施例的觸控顯示裝置之方塊圖。觸控顯示裝置8包括觸控面板81、顯示單元82,觸控面板81位於顯示單元82之上,觸控面板81可以是上述各實施例的其中一種的觸控面板。顯示單元82用以顯示畫面。觸控顯示裝置8還可以包括一觸控感測電路83,其中觸控面板81電性連接觸控感測電路83。觸控感測電路83(包括驅動電路、感測電路與數位信號處理晶片)用以判斷 觸控面板81上是否有信號量的變化,以藉此獲得觸點位置。Please refer to FIG. 5. FIG. 5 is a block diagram of a touch display device according to an embodiment of the present invention. The touch display device 8 includes a touch panel 81 and a display unit 82. The touch panel 81 is located on the display unit 82. The touch panel 81 can be one of the above embodiments. The display unit 82 is for displaying a picture. The touch display device 8 further includes a touch sensing circuit 83. The touch panel 81 is electrically connected to the touch sensing circuit 83. The touch sensing circuit 83 (including a driving circuit, a sensing circuit, and a digital signal processing chip) is used for judging Whether there is a change in the amount of signal on the touch panel 81 to thereby obtain the contact position.
綜上所述,本發明實施例所提供的觸控面板具有較佳且均勻的干擾雜訊抵抗能力、較低的製造成本與較高的可靠性。除此之外,本發明實施例所提供的觸控面板還適用於窄邊框之電子產品的設計。In summary, the touch panel provided by the embodiments of the present invention has better and uniform interference noise resistance, lower manufacturing cost, and higher reliability. In addition, the touch panel provided by the embodiments of the present invention is also applicable to the design of electronic products with narrow frames.
以上所述僅為本發明之實施例,其並非用以侷限本發明之專利範圍。The above description is only an embodiment of the present invention, and is not intended to limit the scope of the invention.
