"upper", "lower", "left", "right", etc. are used merely to denote relative positional relationships, which may also change accordingly when the absolute position of the object to be described changes.
The touch pad 100 may be applied to various terminal devices such as a notebook computer (as shown in fig. 1), a tablet computer, and a mobile phone, and a user may control the terminal device by operating the touch pad 100.
In the related art, in order to make the touch pad 100 have various functions, a manufacturer integrates a component capable of implementing NFC (Near Field Communication ) functions in the touch pad 100, and the component is located at the bottom of the touch pad 100, so that the touch pad 100 has both touch and NFC functions.
As shown in fig. 2, a touch pad 100 in the related art includes a touch signal receiving layer 101, a first insulating setting layer 102, a touch signal transmitting layer 103, a substrate 104, a second insulating setting layer 105, a ground setting layer 106, and an NFC setting layer 107, which are sequentially arranged.
As can be seen from fig. 2, the touch pad 100 in the related art has a larger number of layers, and since the NFC layer is located at the bottom layer of the touch pad 100, six layers of media need to be penetrated during the NFC signal transmission, so that the NFC signal attenuation is more serious.
To solve the above technical problem, the disclosed embodiments provide a touch pad 100, as shown in fig. 3, the touch pad 100 includes a substrate 1, a touch layer 2, and a near field communication NFC layer 3. The touch layer 2 and the NFC layer 3 are respectively located at two sides of the substrate 1, and the touch layer 2 includes a touch receiving electrode 21 and a touch transmitting electrode 22.
The touch pad 100 may also be referred to as a touch pad, and may be applied to a notebook computer, a tablet computer, and a mobile phone.
The substrate 1 is a base material of a PCB (Printed Circuit Board ).
The touch signal receiving layer 101 has a touch receiving electrode therein for receiving a touch signal. The touch signal emitting layer 103 has a touch emitting electrode therein for sending a touch signal to a motherboard of the notebook computer.
The NFC layer 3 is used for transmitting and receiving NFC signals.
According to the technical scheme provided by the embodiment of the disclosure, the touch layer 2 in the touch pad 100 comprises the touch receiving electrode 21 and the touch transmitting electrode 22, so that the receiving and transmitting of the touch signal can be completed in the same layer, the number of layers of the touch pad 100 is reduced, the signal attenuation of the NFC signal is less when the NFC signal penetrates through the touch pad 100, and the intensity of the NFC signal is enhanced. In addition, the number of layers of the touch pad 100 is reduced, so that the manufacturing cost of the touch pad 100 is also reduced.
The following describes an exemplary implementation of the touch layer 2:
in some examples, as shown in fig. 4 to 6, the touch receiving electrode 21 and the touch transmitting electrode 22 are arranged to intersect. The intersection of the touch receiving electrode 21 and the touch transmitting electrode 22 is provided with a first insulating layer 23, one of the touch receiving electrode 21 and the touch transmitting electrode 22 is positioned on the first insulating layer 23, and the other is positioned under the first insulating layer 23, namely, bridging is arranged between the touch receiving electrode 21 and the touch transmitting electrode 22, so that insulation between the touch receiving electrode 21 and the touch transmitting electrode 22 is realized.
As shown in fig. 4-6, the intersection of the touch receiving electrode 21 and the touch transmitting electrode 22 has a first insulating layer 23, the touch receiving electrode 21 is located on the first insulating layer 23, and the touch transmitting electrode 22 is located under the first insulating layer 23. The two adjacent touch receiving electrodes 21 may be electrically connected by a conductive wire, which is located above the first insulating layer 23.
Of course, in other examples, the touch transmitting electrode 22 may be located on the first insulating layer 23, and the touch receiving electrode 21 may be located under the first insulating layer 23.
In some examples, as shown in fig. 4, the touch receiving electrode 21 is arranged perpendicular to the touch transmitting electrode 22.
In some examples, as shown in fig. 4, the touch layer 2 includes a plurality of touch receiving electrodes 21 and a plurality of touch transmitting electrodes 22. The plurality of touch receiving electrodes 21 are arranged at intervals, and the plurality of touch transmitting electrodes 22 are arranged at intervals.
Illustratively, as shown in fig. 4, a plurality of touch receiving electrodes 21 are arranged in parallel and a plurality of touch transmitting electrodes 22 are arranged in parallel.
In order to enhance the anti-interference capability of the touch pad and reduce the mutual interference of the touch signal and the NFC signal, the touch pad further includes a first ground layer 4 and a second insulating layer 5, as shown in fig. 7, where the touch layer 2, the second insulating layer 5, the first ground layer 4 and the substrate 1 are sequentially arranged.
In some examples, as shown in fig. 8, the touch pad 100 further includes a second ground layer 6 and a third insulating layer 7. The substrate 1, the second ground layer 6, the third insulating layer 7 and the NFC layer 3 are arranged in this order.
As illustrated in fig. 9, the touch pad may have a first ground layer 4, a second insulating layer 5, a second ground layer 6, and a third insulating layer 7 at the same time. The patterns of the first ground layer 4 and the second ground layer 6 may be the same or different, specifically, the first ground layer 4 and the second ground layer 6 may be simulated, and specific patterns of the first ground layer 4 and the second ground layer 6 may be designed according to the result of the simulation. Because the touch pad has two layers of grounding layers, the anti-interference capability of the touch pad can be further improved, and the mutual interference between NFC signals and touch signals is reduced.
It should be noted that, after the touch pad 100 is provided with the first grounding layer 4, the second insulating layer 5, the second grounding layer 6 and the third insulating layer 7, the number of layers of the touch pad 100 is still smaller than that of the touch pad in the related art, so that the touch pad 100 in the embodiment of the disclosure can still reduce attenuation of NFC signals.
In other examples, the touch pad may have only the first ground layer 4 and the second insulating layer 5, or may have only the second ground layer 6 and the third insulating layer 7.
The implementation of NFC layer 3 is illustrated below:
as shown in fig. 10, the NFC layer 3 includes an NFC chip 31 and an antenna 32, the NFC chip 31 is electrically connected to the antenna 32, and the antenna 32 is used for receiving and transmitting NFC signals.
In some examples, as shown in fig. 7, the NFC layer 3 further includes a touch chip 33, and the touch chip 33 is electrically connected to the touch receiving electrode 21 and the touch transmitting electrode 22, respectively, for processing touch signals.
In some examples, as shown in fig. 11, the touch pad further includes a cover plate 8, where the cover plate 8 covers the touch layer 2, and the cover plate 8 is used to protect the touch layer 2.
The embodiment of the disclosure further provides a terminal device, as shown in fig. 1, where the terminal device includes the touch pad 100.
The foregoing description of the preferred embodiments of the present disclosure is provided for the purpose of illustration only, and is not intended to limit the disclosure to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, alternatives, and alternatives falling within the spirit and scope of the disclosure.
