Description

Technical field

[0001] The present invention relates to a touch panel and a touch device. [Background Technology]

[0002] In conventional electronic devices such as touch devices or touch display devices, the display panels inside them emit a large amount of electromagnetic waves or are interfered with by the external electromagnetic environment when they are working. Electromagnetic interference (EMI) causes damage to the touch display devices and even worse, endangers the users. In view of this, conventional technology usually adds a grounded metal mesh to the touch panel to shield electromagnetic waves and reduce electromagnetic interference. However, the conventional metal mesh is set up in such a way that it is additionally attached to the touch panel, resulting in problems such as increased thickness of the overall structure of the touch device and increased process steps. Therefore, the conventional touch device has problems such as increased thickness and increased process steps derived from shielding electromagnetic waves.

The electrode stack is disposed on one side of the transparent substrate 110, and the electrode stack includes a first electrode layer 120 and a second electrode layer 130. The first electrode layer 120 includes a first metal grid electrode 121 and a first extending conductive member 122. The first metal grid electrode 121 includes a first touch electrode portion 1212 and a first grounding electrode portion 1211. The first touch electrode portion 1212 is spaced apart from the first grounding electrode portion 1211. The first extending conductive member 122 is connected to the first grounding electrode portion 1211 to form a first grounding terminal 123. A first opening 1215 is provided between the first extending conductive member 122 and the first touch electrode portion 1212, meaning that the first extending conductive member 122 is not connected to the first touch electrode portion 1212. The second electrode layer 130 includes a second metal mesh electrode 131, which includes a second touch electrode portion 1312 and a second ground electrode portion 1311. The second touch electrode portion 1312 is spaced apart from the first touch electrode portion 1212. The first electrode layer 120 and the second electrode layer 130 overlap, and the transparent substrate 110, the first touch electrode portion 1212, and the second touch electrode portion 1312 are positioned opposite each other. In an embodiment of the present invention, the first metal mesh electrode 121 and the second metal mesh electrode 131 can be metal meshes such as copper mesh or silver mesh. The first extending conductive member 122 can be a conductive member such as copper foil or copper sheet, but can also be other conductive members such as silver foil or silver sheet.

[0021] Figure 7 for Figure 1 The following is a schematic diagram of the touch panel in use. Figure 1 、 27. The touch panel 100 of this embodiment can be disposed within a housing 210 to form a touch device 200. That is, the touch device 200 includes the touch panel 100 of this embodiment and the housing 210. The housing 210 has an opening 211. The touch panel 100 is disposed within the housing 210. The transparent substrate 110 of the touch panel 100 is disposed within the opening 211. The electrode stack of the touch panel 100 is disposed within the housing 210. The first ground terminal 123 of the first electrode layer 120 of the electrode stack is connected to the housing 210. In this embodiment, the housing 210 can be a conductive housing, such as, but not limited to, a magnesium-aluminum metal housing. The first ground terminal 123 can be directly or indirectly connected to the housing 210, thereby being grounded through the housing 210. The first ground terminal 123 being indirectly connected to the housing 210 means that a conductive element (not shown) may be disposed between the first ground terminal 123 and the housing 210. The first ground terminal 123 is connected to the housing 210 via the conductive element for grounding. The types of conductive elements include, but are not limited to, screws, wires, springs, brackets, etc. In addition, the touch device 200 may further include a display panel 220. The display panel 220 is connected and disposed within the housing 210 and is located between the housing 210 and the touch panel 100, and is located on the side of the electrode stack away from the transparent substrate 110. The display panel 220 may be, for example, but not limited to, a liquid crystal display panel, an organic light-emitting diode display panel, or a quantum dot display panel. In addition, in one embodiment, the display panel 220 may further include a housing 221. The housing 211 is fixedly connected to the housing 210. The first ground terminal 123 may be connected to the housing 210 via the housing 221 for grounding. In this case, the conductive element may include the housing 221.

[0022] When the display panel 220 is in operation, the user can view the image displayed on the display panel 220 through the opening 211 and the touch panel 100. At the same time, electromagnetic waves emitted by the display panel 220 travel toward the opening 211. In the touch panel 100 and touch device 200 of this embodiment, the first ground electrode portion 1211 of the first metal mesh electrode 121 is connected to the first extending conductive member 122 to form the first ground terminal 123. The first ground terminal 123 is connected to the housing 210 and can be grounded through the housing 210. Therefore, when electromagnetic waves reach the first metal mesh electrode 121, they are shielded by the first ground electrode portion 1211. This effectively reduces electromagnetic interference caused by electromagnetic waves passing through the touch panel 100 and protects the user from the harm of electromagnetic waves. In this embodiment, the first metal mesh electrode 121 is formed from a complete metal mesh. The complete metal mesh is separated to form a first ground electrode portion 1211 and a first touch electrode portion 1212 to form the first metal mesh electrode 121. Consequently, the first ground electrode portion 1211 and the first touch electrode portion 1212 have the same thickness, and the first ground electrode portion 1211 is formed when the first touch electrode portion 1212 is formed, without requiring additional manufacturing steps. Furthermore, it should be understood that while viewing the image displayed on the display panel 220, a user can perform touch input operations on the touch panel 100. During touch input operations, the first touch electrode portion 1212 and the second touch electrode portion 1312 can generate corresponding touch sensing signals, thereby achieving the desired touch input effect. The principle of touch input and the corresponding detailed structure are not essential to this invention and will not be elaborated upon here.

[0023] For ease of explanation, the touch panel 100 and touch device 200 of this embodiment are further described below with reference to a first direction X, a second direction Y, and a third direction Z. The first direction X, the second direction Y, and the third direction Z are distinct and intersecting. In this embodiment, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other, but the present invention is not limited thereto.

[0024] In this embodiment, the transparent substrate 110, the first electrode layer 120, and the second electrode layer 130 are sequentially overlapped along the first direction X, and the second touch electrode portion 1312 is spaced apart from the first touch electrode portion 1212 in the first direction X. However, in other embodiments, the positions of the first electrode layer 120 and the second electrode layer 130 may be swapped, that is, the transparent substrate 110, the second electrode layer 130, and the first electrode layer 120 are sequentially overlapped along the first direction X.

[0025] The first touch electrode portion 1212 further includes a plurality of first touch electrode patterns 1214 sequentially spaced along the second direction Y. The first ground electrode portion 1211 further includes a plurality of first ground electrode patterns 1213, each of which is connected to the first extending conductive member 122. Each first ground electrode pattern 1213 is separately disposed between two first touch electrode patterns 1214, i.e., each first ground electrode pattern 1213 is disposed between two first touch electrode patterns 1214 and spaced apart from two adjacent first touch electrode patterns 1214. Specifically, in the second direction Y, the first ground electrode patterns 1213 are staggered with the first touch electrode patterns 1214. The second touch electrode portion 1312 further includes a plurality of second touch electrode patterns 1314 sequentially spaced along the third direction Z.

[0026] The touch panel 100 further includes a first transparent adhesive layer 140 and a second transparent adhesive layer 150. The first transparent adhesive layer 140 is disposed between the electrode stack and the transparent substrate 110, and the second transparent adhesive layer 150 is disposed between the first electrode layer 120 and the second electrode layer 130. In this embodiment, the first transparent adhesive layer 140 and the second transparent adhesive layer 150 are, for example, but not limited to, optically transparent adhesive layers.

[0027] The first electrode layer 120 further includes a first transparent film 124, which is disposed on a side of the first metal grid electrode 121 away from the transparent substrate 110. The first transparent film 124 comprises a first supporting portion 1241 and a first wing portion 1242, which are connected to each other. The first metal grid electrode 121 is disposed between the first supporting portion 1241 and the first transparent substrate 110. The first touch electrode portion 1212 and the first ground electrode portion 1211 are disposed on the first supporting portion 1241, spaced apart from each other. The first extending conductive member 122 is disposed on the first wing portion 1242 and connected to the first ground electrode portion 1211 to form a first ground terminal 123. The second electrode layer 130 further includes a second transparent film 134, which is disposed on a side of the second metal grid electrode 131 away from the transparent substrate 110. The first wing portion 1242 and the first extending conductive member 122 disposed thereon protrude beyond the periphery of the transparent substrate 110. If desired, the first extending conductive member 122 and the first wing portion 1242 can be bent away from the transparent substrate 110 to form the first grounding end 123. This reduces the width of the touch control device 200 in the third direction Z, facilitating miniaturization of the touch panel 100 and the touch control device 200. Furthermore, the provision of the first opening 1215 enhances the bendability of the first extending conductive member 122. When the first extending conductive member 122 and the first wing portion 1242 are bent away from the transparent substrate 110 to form the first grounding end 123, the first wing portion 1242 can be secured to the second transparent film 134, for example, on the side of the second transparent film 134 away from the second metal grid electrode 131, using the first adhesive 160.

[0028] In this embodiment, the first transparent adhesive layer 140 is disposed between the first metal grid electrode 121 and the transparent substrate 110, and the second transparent adhesive layer 150 is disposed between the first supporting portion 1241 and the second metal grid electrode 131. Furthermore, in this embodiment, the first supporting portion 1241 and the first wing portion 1242 are arranged along the third direction Z, but the present invention is not limited thereto.

[0029] The second electrode layer 130 further includes a second extending conductive member 132. The second metal mesh electrode 131 further includes a second grounding electrode portion 1311. The second touch electrode portion 1312 is spaced apart from the second grounding electrode portion 1311, and the second extending conductive member 132 is connected to the second grounding electrode portion 1311 to form a second grounding terminal 133. The first electrode layer 120 is disposed between the second electrode layer 130 and the transparent substrate 110. A second opening 1315 is defined between the second extending conductive member 132 and the second touch electrode portion 1312, indicating that the second extending conductive member 132 is not connected to the second touch electrode portion 1312. The second extending conductive member 132 can be a conductive member such as copper foil or copper sheet, but can also be other conductive members such as silver foil or silver sheet. In addition, the second ground electrode portion 1311 further includes a plurality of second ground electrode patterns 1313, which are connected to the second extending conductive member 132. Furthermore, each second ground electrode pattern 1313 is separately disposed between two second touch electrode patterns 1314, i.e., each second ground electrode pattern 1313 is disposed between two second touch electrode patterns 1314 and is spaced apart from two adjacent second touch electrode patterns 1314. Specifically, in the third direction Z, the second ground electrode patterns 1313 and the second touch electrode patterns 1314 are alternately arranged. Furthermore, Figure 8 for Figure 1 Please refer to the diagram of another use state of the touch panel shown in the figure for further reference. Figure 8 As shown, the second ground terminal 133 is directly or indirectly connected to the housing 210, thereby being grounded through the housing 210. The indirect connection of the second ground terminal 133 to the housing 210 means that a conductive element (not shown) may be disposed between the second ground terminal 133 and the housing 210, and the second ground terminal 133 is connected to the housing 210 via the conductive element for grounding. The types of conductive elements include, but are not limited to, screws, wires, springs, brackets, etc. Furthermore, in one embodiment, the second ground terminal 133 may be grounded by being connected to the housing 210 via the housing 221 of the display panel 220; in this case, the conductive element may include the housing 221.

[0030] Furthermore, in the touch panel 100 and touch device 200 of this embodiment, the first ground electrode portion 1211 of the first metal mesh electrode 121 is connected to the first extending conductive member 122 to form the first ground terminal 123, and the second ground electrode portion 1311 of the second metal mesh electrode 131 is connected to the second extending conductive member 132 to form the second ground terminal 133. The first and second ground terminals 123 and 133 are connected to the housing 210 and can be grounded through the housing 210. Therefore, when electromagnetic waves reach the electrode stack, they are shielded not only by the first ground electrode portion 1211 but also by the second ground electrode portion 1311. In summary, the first and second ground electrode portions 1211 and 1311 form a double-layer shielding structure, which can further effectively reduce electromagnetic interference caused by electromagnetic waves passing through the touch panel 100 and protect users from the harm of electromagnetic waves. In addition, the second metal grid electrode 131 in this embodiment is made of a complete metal grid. The complete metal grid is separated to form a second ground electrode portion 1311 and a second touch electrode portion 1312 to form the second metal grid electrode 131. As a result, the second ground electrode portion 1311 and the second touch electrode portion 1312 have the same thickness. When the second touch electrode portion 1312 is provided, the second ground electrode portion 1311 is also formed accordingly without inducing additional process steps.

[0031] The second transparent film 134 has a second supporting portion 1341 and a second wing portion 1342 connected to each other. The second metal mesh electrode 131 is disposed between the second supporting portion 1341 and the second transparent adhesive layer 150. The second touch electrode portion 1312 and the second ground electrode portion 1311 are spaced apart and disposed on the second supporting portion 1341. The second extending conductive member 132 is disposed on the second wing portion 1342 and connected to the second ground electrode portion 1311 to form a second ground terminal 133. In this embodiment, the second supporting portion 1341 and the second wing portion 1342 are arranged along the second direction Y, but the present invention is not limited to this. The second wing portion 1342 and the second extending conductive member 132 disposed thereon protrude beyond the periphery of the transparent substrate 110. If desired, the second extending conductive member 132 and the second wing portion 1342 can be bent away from the transparent substrate 110 to form the second ground end 133. This reduces the width of the touch control device 200 in the second direction Y, facilitating miniaturization of the touch panel 100 and the touch control device 200. Furthermore, the provision of the second opening 1315 enhances the bendability of the second extending conductive member 132. When the second extending conductive member 132 and the second wing portion 1342 are bent away from the transparent substrate 110 to form the second ground end 133, the second wing portion 1342 can be secured to the second transparent film 134, for example, on the side of the second transparent film 134 away from the second metal grid electrode 131, using the second adhesive 170.

[0032] In summary, in the touch panel and touch device according to the embodiments of the present invention, the first ground electrode portion of the first metal mesh electrode is connected to the first extending conductive member to form a first ground terminal, and the first ground terminal is connected to the housing and can be grounded through the housing. Therefore, when electromagnetic waves reach the electrode stack, they are shielded by the first ground electrode portion, reducing the amount of electromagnetic waves passing through the touch panel, thereby reducing electromagnetic interference and protecting the user from the harmful effects of electromagnetic waves. The first metal mesh electrode separates the first ground electrode portion from the first touch electrode portion, ensuring that the first ground electrode portion and the first touch electrode portion have the same thickness. The first ground electrode portion is also formed when the first touch electrode portion is formed, without incurring additional manufacturing steps. Therefore, the touch panel and touch device according to the embodiments of the present invention have the advantage of shielding electromagnetic waves without increasing the overall structural thickness or the number of manufacturing steps.
