A conventional capacitive touch panel 1' generally includes two structures, as shown in fig. 1 and 2, the touch panel 1' shown in fig. 1 includes a touch driving electrode Tx20' and a touch sensing electrode Rx10', wherein the touch driving electrode Tx20' and the touch sensing electrode Rx10' are stacked and bonded by an adhesive layer 30', and a cover plate 40' is bonded to a side of the touch sensing electrode Rx10' away from the touch driving electrode Tx20' by the adhesive layer 30 '. The touch driving electrode Tx20 'may emit a low voltage high frequency signal, and the touch sensing electrode Rx10' receives the low voltage high frequency signal, thereby forming a stable capacitance therebetween. The touch of the user may cause different capacitance changes between the touch driving electrode Tx20 'and the touch sensing electrode Rx10', and the touch position may be determined according to the capacitance changes.
The touch panel 1' shown in fig. 2 includes a self-contained touch electrode 50', and the self-contained touch electrode 50' is adhered to one side of the cover 40' by an adhesive layer 30 '. The self-capacitance type touch electrode 50 'and the ground form a self-capacitance, after the finger of the user touches the cover plate 40', the capacitance of the finger is superposed on the self-capacitance, so that the capacitance is increased, and the touch position can be determined according to the change of the self-capacitance before and after the finger touches.
However, the electrical touch signals of the two touch panels 1 'are transmitted to the integrated circuit 4' through the leads 2 'and the circuit board 3'. Specifically, referring to fig. 3, the complex lead wires 2 'are disposed around the touch sensing electrodes Rx10' and the touch driving electrodes Tx20 '(not shown), and the electrical signals of the touch driving electrodes Tx20' and the touch sensing electrodes Rx10 'are sequentially transmitted to the integrated circuit 4' through the lead wires 2 'and the circuit board 3'. However, such a touch panel 1' has at least the following drawbacks: on one hand, the lead wires 2' at the periphery of the touch sensing electrode Rx10' and the touch driving electrode Tx20' are complicated to arrange, which not only increases the design difficulty but also increases the preparation difficulty; on the other hand, bonding (bonding) needs to be performed on the circuit board 3', so that the preparation difficulty is increased, and meanwhile, the preparation yield of the touch panel 1' is reduced due to the fact that the bonding process has a certain reject ratio.
In view of this, in order to solve at least one of the above problems, embodiments of the present application provide a touch module and a touch electronic device, which can reduce the design difficulty and the manufacturing difficulty of the touch module and the touch electronic device, thereby improving the manufacturing efficiency and the manufacturing yield of the touch module and the touch electronic device.

Referring to fig. 4, the touch electronic device 1 includes a touch module 50 and a main board 10. Wherein, a receiving antenna 20 is disposed on the main board 10.

The touch electronic device 1 provided by the present application is provided with a transmitting antenna 52 electrically connected to the touch electrode layer 51, and a receiving antenna 20 electrically connected to the main board 10. In this way, the touch signal sensed by the touch electrode layer 51 may be wirelessly transmitted to the main board 10 of the touch electronic device 1, and the main board 10 processes the received touch signal to obtain touch information. Compared with the conventional touch module 50, the touch electronic device 1 of the present application does not need to set complex routing lines at the periphery of the touch electrode layer 51, so as to reduce the design difficulty and the setting difficulty of the routing lines; on the other hand, the circuit board is removed, and bonding (bonding) is not needed for the circuit board, so that the preparation efficiency and the preparation yield are improved; on the other hand, the touch chip can be integrated on the main board 10, so that the touch chip does not need to be disposed on the touch module 50, and the difficulty in manufacturing the touch module 50 is reduced.
In one embodiment, the touch module 50 further includes a receiving coil 53 electrically connected to the touch electrode layer 51, and the touch electronic device 1 further includes a transmitting coil 40 electrically connected to the main board 10. The transmitting coil 40 is used for transmitting energy to the receiving coil 53, and the receiving coil 53 is used for receiving the energy transmitted by the transmitting coil 40 to generate electric energy and supply the electric energy to the touch electrode layer 51, so that the touch electrode layer 51 can form stable capacitance. The capacitance change is changed by the touch operation of the user's finger, and the main board 10 can determine the position touched by the finger according to the capacitance change.
In one embodiment, the material of the receiving antenna 20, the transmitting coil 40, the transmitting antenna 52 and the receiving coil 53 may be ITO (Indium tin oxide), gold, silver, copper, aluminum, tungsten, nickel, etc. Wherein the resistance value of the ITO is less than 20 ohms.
It should be noted that the touch electronic device 1 further includes a battery module 30, one electrical connection end of the battery module 30 is connected to the main board 10, and the other electrical connection end is electrically connected to the transmitting coil 40. The main board 10 controls the battery module 30 to supply power to the transmitting coil 40, the transmitting coil 40 transmits power to the receiving coil 53 through magnetic field induction, and the receiving coil 53 generates power through induction and supplies the power to the touch electrode layer 51. The voltage output by the receiving coil 53 is between 2.8V and 20V, so that on one hand, the normal operation of the touch electrode layer 51 can be ensured, on the other hand, the voltage is prevented from being too high, and the safety of a user during touch is ensured. It is understood that the touch electrode layer 51 may be any one of a self-capacitance touch electrode and a mutual capacitance touch electrode.
In one embodiment, referring to fig. 5 and 6, the touch electronic device 1 further includes a display module 60 electrically connected to the main board 10, and the touch module 50 is disposed on a light emitting side of the display module 60. The Display module 60 may be an Organic Light-Emitting Diode (OLED) Display module, a Liquid Crystal Display (LCD) Display module, a submillimeter Light-Emitting Diode (Mini LED) Display module, or a Micro LED Display module.
In this embodiment, the battery module 30 and the transmitting coil 40 may be disposed on the backlight side of the display module 60, and the orthographic projections of the transmitting coil 40 and the receiving coil 53 on the display module 60 have an overlapping region. In this way, the distance between the transmission coil 40 and the reception coil 53 can be made closer, thereby making the wireless charging more effective.
It can be understood that the touch module 50 and the display module 60 can have the following two configurations:
in one embodiment, as shown in fig. 5, the touch electrode layer 51 has only one layer, that is: the touch electrode layer 51 only includes the first electrode layer 511, the transmitting antenna 52 includes the first transmitting antenna 521 electrically connected to the first electrode layer 511, and the receiving coil 53 includes the first receiving coil 531 electrically connected to the first electrode layer 511. The first transmitting antenna 521 and the first receiving coil 531 are respectively disposed at two opposite ends of the first electrode layer 511 in a first direction, where the first direction is perpendicular to the thickness direction of the touch electrode layer 51. In addition, adhesive layers 70 may be disposed between the touch electrode layer 51 and the display module 60 and between the touch electrode layer 51 and the cover plate 80, so as to firmly connect the touch electrode layer 51, the cover plate 80 and the display module 60.
In another embodiment, as shown in fig. 6, the touch electrode layer 51 has two layers, namely: the touch electrode layer 51 includes a first electrode layer 511 and a second electrode layer 512. The first electrode layer 511 may be a transmitting electrode, and the second electrode layer 512 may be a receiving electrode. For one embodiment, the first electrode layer 511 may be located on a side of the second electrode layer 512 close to the display module 60.
Specifically, the transmitting antenna 52 includes a first transmitting antenna 521 electrically connected to the first electrode layer 511, and the receiving coil 53 includes a first receiving coil 531 electrically connected to the first electrode layer 511. The first transmitting antenna 521 and the first receiving coil 531 are respectively disposed at two opposite ends of the first electrode layer 511 in the first direction. The transmitting antenna 52 includes a second transmitting antenna 522 and the receiving coil 53 includes a second receiving coil 532. The second transmitting antenna 522 and the second receiving coil 532 are respectively disposed at two opposite ends of the second electrode layer 512 in a second direction, where the second direction is perpendicular to the thickness direction of the touch electrode layer 51 and the first direction. In this way, on one hand, the first receiving coil 531 and the second receiving coil 532 can be staggered in the thickness direction of the touch electrode layer 51, so as to avoid the occurrence of error charging between the two; on the other hand, the first transmitting antenna 521 and the second transmitting antenna 522 may be staggered in the thickness direction of the touch electrode layer 51, so as to avoid signal interference between the two antennas.
In another embodiment, the first electrode layer 511 may be disposed in the same layer as the second electrode layer 512. For example, the first electrode layer 511 may be arranged in a row direction, the second electrode layer 512 may be arranged in a column direction, and a coupling capacitor is formed between the first electrode layer 511 and the second electrode layer 512. It is to be understood that when the first electrode layer 511 and the second electrode layer 512 are located at the same layer, the first receiving coil 531, the second receiving coil 532, the first transmitting antenna 521 and the second transmitting antenna 522 are all located at the layer where the first electrode layer 511 and the second electrode layer 512 are located.
In one embodiment, referring to fig. 7 and 8, the touch module 50 may also be disposed on the substrate layer 90, that is: the touch module 50 is not disposed on the display screen. For example: touch pad on notebook computer.

A battery module 30 and a transmitting coil 40 are arranged on the side of the protective layer 100 close to the first electrode layer 511 facing away from the first electrode layer 511.
In one embodiment, referring to fig. 9, the first electrode layer 511 includes a plurality of first sub-electrodes 5111 arranged at intervals along the second direction b, and each of the first sub-electrodes 5111 extends along the first direction a. The first transmitting antenna 521 includes a plurality of first sub-antennas 5211, the first receiving coil 531 includes a plurality of first sub-coils 5311, and the plurality of first sub-antennas 5211 and the plurality of first sub-coils 5311 are connected to the first sub-electrode 5111 in a one-to-one correspondence. The second direction b is perpendicular to the thickness direction of the touch electrode layer 51 and the first direction a.
In this way, each first sub-coil 5311 can individually supply power to each first sub-electrode 5111, and each first sub-antenna 5211 individually transmits the touch signal of each first sub-electrode 5111. On one hand, the short circuit caused by the electrical contact between the first sub-electrodes 5111 is avoided; on the other hand, the touch signals of the plurality of first sub-electrodes 5111 can be prevented from being transmitted by the same first transmitting antenna 521, so that the main board 10 can accurately identify the touch position after receiving the signals.
In one embodiment, referring to fig. 10, the second electrode layer 512 includes a plurality of second sub-electrodes 5121 arranged at intervals along the first direction a, and each of the second sub-electrodes 5121 extends along the second direction b. The second transmitting antenna 522 includes a plurality of second sub-antennas 5221, the second receiving coil 532 includes a plurality of second sub-coils 5321, and the plurality of second sub-antennas 5221 and the plurality of second sub-coils 5321 are each connected to the second sub-electrode 5121 in a one-to-one correspondence.
In this way, each second sub-coil 5321 individually supplies power to each second sub-electrode 5121, and each second sub-antenna 5221 individually transmits the touch signal of each second sub-electrode 5121. On one hand, the short circuit caused by the electrical contact between the second sub-electrodes 5121 is avoided; on the other hand, the touch signals of the plurality of second sub-electrodes 5121 can be prevented from being transmitted by the same second transmitting antenna 522, so that the main board 10 can accurately identify the touch position after receiving the signals.
In one embodiment, as shown in fig. 9 and 10, the arrangement region of the first transmitting antenna 521 and the first receiving coil 531 may be located in an outer extension region of the first electrode layer 511, which starts at a side of the first electrode layer 511 and extends in a first direction a toward a direction away from the first electrode layer 511. The outer extension has a length L in the first direction a.
