[0060] Figure 1A FIG1 is a top view of an electronic device according to an embodiment of the present disclosure. Figure 1B for Figure 1A An enlarged schematic diagram of region R1.

[0061] Please refer to Figure 1A, the electronic device 100 of this embodiment has a display area 110 and a peripheral area 120, and the peripheral area 120 is adjacent to and surrounds the display area 110. The display area 110 has a touch area 111, a touch area 112 and a non-touch area 113. Among them, the touch area 111 and the touch area 112 are respectively arranged on the left and right sides of the display area 110, and the non-touch area 113 is arranged in the middle of the display area 110. That is, the non-touch area 113 is arranged between the touch area 111 and the touch area 112, but is not limited to this. The size of the non-touch area 113 is, for example, larger than or similar to the size of the touch area 111 (or the size of the touch area 112), but is not limited to this. In addition, the touch area 111 and the touch area 112 both have touch functions, and the non-touch area 113 does not have a touch function.

[0062] Please also refer to Figure 1A and Figure 1B The electronic device 100 of this embodiment includes an electrode layer 130. The electrode layer 130 is disposed in the touch area 111, the touch area 112, and the non-touch area 113. The electrode layer 130 includes a plurality of touch electrodes 131, a plurality of first electrodes 132a, a plurality of second electrodes 132b, a plurality of floating electrodes 133, and gaps 134. The material of the electrode layer 130 may include a transparent conductive material. For example, the material of the electrode layer 130 may be, but is not limited to, indium tin oxide, indium zinc oxide, indium oxide, zinc oxide, tin oxide, other suitable transparent conductive materials, or combinations thereof.

[0063] In this embodiment, a plurality of touch electrodes 131 are disposed in the touch area 111 and the touch area 112. A gap 134 is defined between two adjacent touch electrodes 131 within the plurality of touch electrodes 131. Adjacent touch electrodes 131 are defined as the two closest touch electrodes 131, with no other touch electrodes between them. In some embodiments, the electrode layer 130 disposed in the touch area 111 is not grounded. In some embodiments, a portion of the electrode layer 130 disposed in the touch area 111 may be grounded while another portion is not, but this is not a limitation.

[0064] A plurality of first electrodes 132a are disposed in the non-touch area 113. The plurality of first electrodes 132a may be grounded. A gap 134 is provided between two adjacent first electrodes 132a among the plurality of first electrodes 132a. The two adjacent first electrodes 132a refer to the two closest first electrodes 132a, and there is no other first electrode between the two closest first electrodes 132a. In addition, in the present embodiment, the pattern (or shape) of the plurality of touch electrodes 131 is similar to the pattern (or shape) of the plurality of first electrodes 132a, thereby reducing the impact on the visibility of the electronic device 100. The "similar" may include the same or similar outer contours, and the areas are substantially the same or the area difference is within 10%.

[0065] A plurality of second electrodes 132b are disposed in the non-touch area 113. At least one second electrode 132b serves as part of the first touch signal line 160 and is electrically connected to at least one touch electrode 131. Furthermore, in this embodiment, the pattern (or shape) of the plurality of second electrodes 132b is similar to the pattern (or shape) of the plurality of first electrodes 132a, thereby minimizing the impact on the visibility of the electronic device 100. The term "similar" may include identical or similar outer contours, and substantially identical areas or an area difference within 10%.

[0066] A plurality of floating electrodes 133 are disposed in the touch area 111, the touch area 112, and the non-touch area 113. Each of the floating electrodes 133 has a gap 134 around it, so that each floating electrode 133 is separated and electrically isolated from its adjacent electrodes. Adjacent floating electrodes 133 are separated from the touch electrodes 131, and adjacent floating electrodes 133 are separated from the first electrodes 132a. Two adjacent floating electrodes 133 refer to the two closest floating electrodes 133, with no other first electrodes 132a or touch electrodes 131 between them. Adjacent floating electrodes 133 and touch electrodes 131 refer to the closest floating electrodes 133 and touch electrodes 131, with no other first electrodes 132a or touch electrodes 131 between them. The adjacent floating electrodes 133 and first electrodes 132 a refer to the floating electrodes 133 and first electrodes 132 a that are closest to each other, and there is no other first electrode 132 a or touch electrode 131 between the closest floating electrodes 133 and first electrodes 132 a .

[0067] Please continue to refer to Figure 1A and Figure 1BThe electronic device 100 of this embodiment further includes a driver chip 140, a second touch signal line 150, and a first touch signal line 160. The driver chip 140 may be disposed in the peripheral area 120, but is not limited thereto. The driver chip 140 may be, for example, a touch IC, but is not limited thereto. In some embodiments, the driver chip may also be disposed in a non-display area of ​​the electronic device via a flexible printed circuit (FPC), such as Figure 2A shown.

[0068] The first touch signal line 160 is disposed in the non-touch area 113. The first touch signal line 160 includes a plurality of second electrodes 132b and a first conductive layer 161. The first conductive layer 161 is disposed between two adjacent second electrodes 132b in the first touch signal line 160. This allows the two adjacent second electrodes 132b to be electrically connected via the first conductive layer 161. The term "two adjacent second electrodes 132b" refers to the two closest second electrodes 132b, with no other second electrodes 132b between them. In this embodiment, each first touch signal line 160 is electrically isolated from another. A first touch signal line 160 is electrically connected to the touch electrode 131, and a portion of the first touch signal line 160 is located between two adjacent first electrodes 132a. For example, the first touch signal line 160 includes a second electrode 132b. The outer contour of the second electrode 132b has four sides, two of which are adjacent to the first electrode 132a. The patterns of the first electrode 132a and the second electrode 132b are similar. In addition, at least a portion of the first touch signal line 160 (for example, the second electrode 132b with a three-sided outer contour) is located between two adjacent first electrodes 132a and the touch electrode 131. The two adjacent first electrodes 132a and the touch electrode 131 are the two first electrodes 132a and the touch electrode 131 that are closest to each other, and there is no other first electrode 132a or touch electrode 131 between the two closest first electrodes 132a and the touch electrode 131.

[0069] The first touch signal line 160 has an end 162 and a first end 163 opposite end 162. End 162 is distal from the touch area 111 (or touch area 112), while first end 163 is adjacent to the touch area 111 (or touch area 112). The first end 163 of the first touch signal line 160 can contact and electrically connect to at least one touch electrode 131. The end 162 of the first touch signal line 160 can be electrically connected to the conductive line 142. In other words, the driver chip 140 can drive the touch area 111 (or touch area 112) via the at least one first touch signal line 160 located in the non-touch area 113.

[0070] In some embodiments, multiple second touch signal lines 150 are disposed in the peripheral region 120. These second touch signal lines 150 can be electrically connected to the conductive lines 141. The multiple second touch signal lines 150 are electrically connected to the touch electrodes 131 and the driver chip 140, respectively. In other words, the driver chip 140 can drive the touch area 111 (or touch area 112) via the at least one second touch signal line 150 located in the peripheral region 120. Driving the touch area 111 (or touch area 112) via the first touch signal lines 160 and the second touch signal lines 150 achieves a bilateral driving effect, thereby reducing the overall resistance and capacitance load.

[0071] In this embodiment, the number of the first touch signal lines 160 may be, for example, greater than or equal to the number of the second touch signal lines 150, but is not limited thereto. Furthermore, in some embodiments, the first touch signal lines 160 and the second touch signal lines 150 are respectively disposed on opposite sides of the touch area 111 (or touch area 112).

[0072] The following examples are provided for illustration purposes only. It should be noted that the following examples share the same component numbers and some of the details as the previous examples, with the same numbers used to represent the same or similar components, and descriptions of the same technical details omitted. For the omitted details, please refer to the previous examples, and the following examples will not be repeated.

[0073] Figure 2A FIG1 is a top view of an electronic device according to another embodiment of the present disclosure. Figure 2B for Figure 2A Please also refer to the enlarged schematic diagram of area R2. Figure 1A-1B and Figure 2A-2B The electronic device 100a of this embodiment is substantially similar to Figure 1A-1B Therefore, the same and similar components between the two embodiments will not be repeated here. The electronic device 100a of this embodiment differs from the electronic device 100a mainly in that, in the electronic device 100a of this embodiment, the driver chip 140a is disposed in the non-display area of ​​the electronic device 100a, such as the back side of the touch area 111a, via a flexible printed circuit board 145. However, this is not limited to this. For example, in other embodiments, the driver chip 140a can be disposed on the front side of the peripheral area via a flexible printed circuit board 145.

[0074] Specifically, please refer to Figure 2A and Figure 2B, the electronic device 100a of this embodiment does not have a peripheral area, and the size of the non-touch area 113a is, for example, larger than or similar to the size of the touch area 111a, but not limited thereto. The driver chip 140a located on the non-display surface can be electrically connected to the second touch signal line 150 and the end 162 of the first touch signal line 160 through the conductive line 141a and the conductive line 142a, respectively. Then, since the first end 163 of the first touch signal line 160 can also contact and be electrically connected to the touch electrode 131, the driver chip 140a can drive the touch area 111a through the second touch signal line 150 located in the peripheral area 120, and can also drive the touch area 111a through the first touch signal line 160 located in the non-touch area 113a and the second touch signal line 150 located in the peripheral area 120, so as to achieve a bilateral driving effect, thereby reducing the overall resistance and capacitance load. Among them, as Figure 2B As shown, the first touch signal line 160 includes a plurality of second electrodes 132 b and a first conductive layer 161 .

[0075] Figure 3A FIG1 is a top view of an electronic device according to another embodiment of the present disclosure. Figure 3B for Figure 3A An enlarged schematic diagram of region R3. Figure 3C for Figure 3B An enlarged schematic diagram of region R4. Figure 3D for Figure 3B An enlarged schematic diagram of region R5. Figure 3E for Figure 3A Please also refer to the enlarged diagram of area R6. Figure 1A-1B and Figure 3A-Figure 3E The electronic device 100b of this embodiment is substantially similar to Figures 1A-1B Therefore, the same or similar components between the two embodiments will not be repeated here. The electronic device 100b of this embodiment differs from the electronic device 100b primarily in that the size of the non-touch area 113b is significantly smaller than the size of the touch area 111b (or the size of the touch area 112b). Furthermore, the electronic device 100b of this embodiment further includes a third touch signal line 170 disposed in the non-touch area 113b.

[0076] Specifically, please refer to Figures 3A to 3DThe size of the non-touch area 113b is, for example, less than half the size of the touch area 111b (or the size of the touch area 112b), but is not limited thereto. In this embodiment, because the size of the non-touch area 113b is significantly smaller than the size of the touch area 111b (or the size of the touch area 112b), insufficient second electrodes 132b are available in the non-touch area 113b to serve as first touch signal lines 160. Consequently, the driver chip 140 cannot be electrically connected to at least a portion of the touch electrodes 131 solely via the first touch signal lines 160. Therefore, in this embodiment, third touch signal lines 170 are provided in the non-touch area 113b. This allows the driver chip 140 to electrically connect to at least a portion of the touch electrodes 131 via the first and third touch signal lines 160, thereby driving the touch electrodes 131.

[0077] Specifically, the third touch signal line 170 includes a plurality of second electrodes 132b, a first conductive layer 161, and a connecting line 171 disposed between the plurality of first electrodes 132a. The connecting line 171 may be formed by connecting some of the floating electrodes 133 in series, but is not limited thereto. In this embodiment, the third touch signal lines 170 are electrically isolated from each other, and the first touch signal lines 160 and the third touch signal lines 170 are also electrically isolated from each other. Figure 3C and Figure 3D shown.

[0078] Furthermore, the third touch signal line 170 has an end 172 and a first end 173. End 172 is distal from the touch region 111b (or touch region 112b), while first end 173 is adjacent to the touch region 111b (or touch region 112b). End 172 of the third touch signal line 170 can be electrically connected to the driver chip 140 via the conductive line 142b located in the peripheral region 120. The first end 173 of the third touch signal line 170 can contact and electrically connect to the touch electrode 131. This allows the touch electrode 131 to be electrically connected to the driver chip 140 via the third touch signal line 170, thereby enabling the touch region 111b (or touch region 112b) to have a touch function. In other words, the driver chip 140 can drive the touch area 111b (or touch area 112b) via the first touch signal line 160 located in the non-touch area 113b and the second touch signal line 150 located in the peripheral area 120, and can also drive the touch area 111b (or touch area 112b) via the third touch signal line 170 located in the non-touch area 113b, thereby achieving a bilateral driving effect and reducing the overall resistance and capacitance load.

[0079] Furthermore, in this embodiment, the first touch signal lines 160 can be further divided into a group 160a and a first group 160b, and the third touch signal lines 170 can also be divided into a group 170a and a first group 170b. The group 160a of the first touch signal lines 160 and the group 170a of the third touch signal lines 170 can each be electrically connected to the touch area 111b, while the first group 160b of the first touch signal lines 160 and the first group 170b of the third touch signal lines 170 can each be electrically connected to the touch area 112b. This allows both the touch areas 111b and 112b, located on either side of the non-touch area 113b, to achieve a dual-side driving effect.

[0080] Figure 4 This is a top view of an electronic device according to another embodiment of the present disclosure. Figure 3A and Figure 4 The electronic device 100c of this embodiment is substantially similar to Figure 3A Therefore, the same and similar components of the two embodiments will not be repeated here. The electronic device 100c of this embodiment is different from the electronic device 100b mainly in that the electronic device 100c of this embodiment is Figure 3A The touch area 112b in the electronic device 100b is changed into a non-touch area.

[0081] Specifically, please refer to Figure 4 In this embodiment, the non-touch area 113c of the electronic device 100c includes an area 113c1 and a first area 113c2. The area 113c1 can be regarded as Figure 3A The non-touch area 113b in the first area 113c2 can be regarded as Figure 3A The first region 113c2 of the non-touch region 113c still has a first touch signal line (not shown). However, in this embodiment, the first electrode in the first region 113c2 can be grounded and not electrically connected to the driver chip. In other words, the first region 113c2 does not have a touch function.

[0082] Furthermore, because the size of the touch area 111b is substantially smaller than that of the non-touch area 113c, in other words, because the size of the non-touch area 113c is substantially larger than that of the touch area 111b, the non-touch area 113c, in addition to having a first area 113c2 of similar size to the touch area 111b for disposing the first touch signal line and / or the third touch signal line (not shown), also has an area 113c1 for disposing the first touch signal line 160 and / or the third touch signal line 170. In other embodiments, the peripheral area 120 may further be provided with the second touch signal line 150, so that the touch area 111b can achieve a bilateral driving effect.

[0083] Figure 5A FIG1 is a top view of an electronic device according to another embodiment of the present disclosure. Figure 5B for Figure 5A Please also refer to the enlarged diagram of area R7. Figure 4 and Figure 5A The electronic device 100d of this embodiment is substantially similar to Figure 4 Therefore, the same and similar components in the two embodiments will not be repeated here. The electronic device 100d of this embodiment is different from the electronic device 100c mainly in that the non-touch area 113d of the electronic device 100d of this embodiment does not have the area 113c1 of the electronic device 100c.

[0084] Specifically, please refer to Figure 5A and Figure 5B In this embodiment, the non-touch area 113d of the electronic device 100d can be regarded as Figure 4 Therefore, the non-touch area 113d still has the first touch signal line 160, and the first electrode 132a of the non-touch area 113d can be grounded and not electrically connected to the driver chip. In other words, the non-touch area 113d does not have a touch function.

[0085] In addition, in this embodiment, the electrode layer pattern at the junction of the touch area 111b and the non-touch area 113d is divided into two halves to prevent the electrode layer in the non-touch area 113d from being electrically connected to the touch electrode 131 in the touch area 111b. The method of dividing the electrode layer pattern is, for example, to divide the electrode layer pattern into two halves in a zigzag manner in the middle of the electrode layer. Figure 5B shown.

[0086] Figure 6A FIG1 is a top view of an electronic device according to another embodiment of the present disclosure. Figure 6B for Figure 6A Please also refer to the enlarged diagram of area R8. Figure 3B-3D and Figure 6A-6B The electronic device 100e of this embodiment is roughly similar to Figure 3B-3D The electronic device 100e of this embodiment differs from the electronic device 100b mainly in that the electronic device 100e of this embodiment further includes a fourth touch signal line 180 and a fifth touch signal line 190 disposed in the non-touch area 113e.

[0087] Specifically, please refer to Figure 6A and Figure 6BThe second electrode 132b in the non-touch area 113e is cut into connecting lines 132b1, 132b2, 132b3, and 132b4 at gaps 134. Connecting lines 132b1, 132b2, 132b3, and 132b4 are separated from each other. Connecting line 132b1 serves as part of the fourth touch signal line 180, connecting line 132b2 serves as part of the fifth touch signal line 190, connecting line 132b3 serves as part of the sixth touch signal line, and connecting line 132b4 serves as part of the seventh touch signal line. In this way, sufficient touch signal lines (including the third touch signal line 170, the fourth touch signal line 180, and the fifth touch signal line 190, but not limited thereto) can be set in the limited space of the non-touch area 113e, so that the touch signal lines in the non-touch area 113e are sufficient to be electrically connected to all the touch signal lines located in the touch area.

[0088] In summary, in the electronic device of the disclosed embodiment, since the driver chip can drive the touch area through the end of the touch signal line located in the touch area, and can also drive the touch area through the first touch signal line located in the non-touch area and the first end of the touch signal line located in the touch area, the electronic device of the present embodiment can drive the touch area in a bilateral driving manner to reduce the overall resistance and capacitance load.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
