A touch sensor according to an embodiment of the first aspect of the invention is described below with reference to fig. 1-4.
As shown in fig. 1, a touch sensor 100 according to an embodiment of the first aspect of the invention includes a grid electrode layer 102.
Specifically, the grid electrode layer 102 includes a plurality of touch driving channels 2, a plurality of sensing channels 3 and an antenna channel 1, the plurality of touch driving channels 2 and the plurality of sensing channels 3 are arranged in a staggered manner, two adjacent touch driving channels 2 are electrically isolated, each touch driving channel 2 includes a plurality of first grids 21, the plurality of first grids 21 are connected with each other, each sensing channel 3 includes a plurality of second grids 31, two second grids 31 of two adjacent sensing channels 3 are electrically connected through a conductive bridge 4, the antenna channel 1 includes at least one antenna segment 11, one end of the antenna segment 11 is coupled with at least one second grid 31, and the antenna channel 1, the plurality of touch driving channels 2 and the plurality of sensing channels 3 are all located in the same plane.
For example, in the example of fig. 1, a plurality of first grids 21 arranged at intervals in the longitudinal direction (for example, the up-down direction in fig. 1) form the touch driving channels 2, a plurality of second grids 31 arranged at intervals in the transverse direction (for example, the left-right direction in fig. 1) form the sensing channels 3, and two adjacent second grids 31 in each sensing channel 3 are electrically connected through the conductive bridges 4. The antenna path 1 comprises at least one antenna segment 11, and one end of the antenna segment is coupled to at least one second grid 31, i.e. one end of the antenna segment may be connected to one second grid 31, or the antenna segment is located between two adjacent second grids 31. The antenna channel 1, the touch driving channel 2 and the induction channel 3 are all located in the same plane. The antenna channel 1 may be used for transmitting or receiving electromagnetic waves. Therefore, the antenna channel 1, the touch driving channel 2 and the sensing channel 3 are all arranged in the same layer, so that the thickness of the touch sensor 100 is effectively reduced, the manufacturing procedures of the touch sensor are reduced, and the cost is reduced.
According to the touch sensor 100 of the embodiment of the invention, the two adjacent second grids 31 of each sensing channel 3 are electrically connected through the conductive bridge 4, and the antenna segment 11 of the antenna channel 1 is connected between the two second grids 31 of the two adjacent sensing channels 3, so that the antenna channel 1, the touch driving channel 2 and the sensing channels 3 can be well arranged in the same plane, thereby effectively reducing the thickness of the touch sensor 100, reducing the manufacturing procedures of the touch sensor 100 and reducing the cost.
According to some embodiments of the present invention, the antenna channel 1 is disposed at an edge of the grid electrode layer 102, the plurality of antenna segments 11 are multiple, the plurality of antenna segments 11 include a plurality of first antenna segments 111 and a plurality of second antenna segments 112, one end of each of the plurality of first antenna segments 111 is connected to each of the plurality of second grids 31 of the outermost plurality of sensing channels 3, and each of the plurality of second antenna segments 112 is connected between two second grids 31 of the outermost adjacent plurality of sensing channels 3. In the description of the present invention, "a plurality" means two or more. For example, in the example of fig. 1, the uppermost end of the touch sensor 100 is the edge of the sensing channel 3, the first antenna segment 111 is connected to the upper end of the second grid 31 at the edge, and the second antenna segment 112 is connected between the two second grids 31 at the edge. Because the touch use frequency at the edge of the screen of the electronic equipment is low, the influence on the touch function can be reduced to the maximum extent.
Optionally, in the example of fig. 1, a plurality of second antenna segments 112 are respectively connected between two second grids 31 of two neighboring induction channels 3 at the extreme edges. Therefore, the touch function of the touch sensor is further ensured.
According to some embodiments of the present invention, the touch sensor 100 further includes a plurality of insulating members 5, and each insulating member 5 is disposed between the conductive bridge 4 and a portion of the touch driving channel 2 corresponding to the conductive bridge 4. For example, referring to fig. 1, the insulating member 5 is located at the overlapping portion of the conductive bridge 4 and the touch driving channel 2 and the conductive bridge 4. By the arrangement, the insulation effect between the overlapping parts of the touch driving channel 2 and the conductive bridge 4 is effectively ensured, and the short circuit between the touch driving channel 2 and the induction channel 3 is avoided.
Further, the adjacent sensing channels 3 at the extreme edge of the grid electrode layer 102 are time-shared as touch components or antenna components, for example, in one cycle, the sensing channels 3 are used as touch components in half of the time and used as antenna components in the other half of the time. Therefore, the functions of touch control and antenna are effectively realized, and the antenna and the touch control are integrated in the same layer.
Optionally, two adjacent sensing channels 3 at the edge of the grid electrode layer 102 are time-shared as a touch component or an antenna component. Because the frequency of use of the touch control at the edge of the sensing channel 3 is low, the influence on the touch control function can be reduced to the maximum extent.
Alternatively, both ends of each insulating member 5 extend onto the surfaces of two adjacent second grids 31, respectively. For example, in the example of fig. 1, the left and right ends of the insulating member 5 extend onto the surfaces of two adjacent second grids 31 on the left and right sides, respectively, and the length of the insulating member 5 is greater than the distance between the two adjacent second grids 31. Therefore, the insulation range is enlarged, and a better insulation effect can be achieved.
Optionally, the width of each insulating member 5 is larger than the width of the conductive bridge 4. For example, referring to fig. 1, the insulating member 5 may be symmetrically disposed about a central axis in a length direction of the conductive bridge 4, and a width of the insulating member 5 in the up-down direction shown in fig. 1 is larger than a width of the conductive bridge 4 in the up-down direction. So set up, can effectively guarantee the insulating effect of conductive bridge 4 department equally to signal transmission's smoothness nature has been guaranteed.
According to some embodiments of the present invention, each touch driving channel 2 includes a plurality of first grids 21, and two adjacent first grids 21 are connected by a connecting segment, wherein a width of each insulating member 5 is greater than or equal to a length of the connecting segment. For example, in the example of fig. 1, a plurality of first grids 21 are connected by connecting segments to form a first touch driving channel 2. From this, through setting up the linkage segment, guaranteed the transmission of signal between first net 21, moreover, through setting up the width of insulating part 5 into the length of more than or equal to linkage segment, can further effectively guarantee the insulating effect of linkage segment department.
Optionally, the width of each insulator 5 is equal to the length of the connecting section. Therefore, the insulation effect at the connecting section is effectively ensured, and the use of the material of the insulating piece 5 is reduced, so that the cost can be saved.
According to some embodiments of the invention, each second mesh 31 is formed with a groove 32, and the ends of the antenna segments 11 fit within the grooves 32. For example, in the example of fig. 1, the second grids 31 are square, two grooves 32 are provided on each second grid 31, the two grooves 32 are respectively located at opposite corners (for example, two upper and lower opposite corners in fig. 1) of the second grid 31, and the ends of the antenna segments 11 are fitted in the grooves 32. Thus, the second mesh 31 acts as a passive component for receiving the touch signal, and the influence on the antenna signal is reduced. Meanwhile, coupling connection between the antenna segment 11 and the second grid 31 is realized, and the touch driving channel 2 can be locally converted into an antenna pattern by coupling connection (for example, pattern channel coupling, that is, functions of touch and antenna can be simultaneously realized by using several T second grid 31 channels at the edge of the visible area as time-sharing antennas), so as to realize transmission and reception of signals. The touch driving channel 2, the sensing channel 3 and the antenna channel 11 are guaranteed to be arranged in the same layer, so that the thickness of the touch sensor 100 can be reduced, the manufacturing procedure of the antenna channel 1 does not need to be additionally increased, the manufacturing process is reduced, and the cost is reduced.
