In the existing notebook computer, the NFC antenna is generally disposed below the touch electrode of the touch pad, so that the notebook computer can integrate an NFC function. Or the NFC antenna coil is arranged on the other side of the notebook computer touchpad, and the periphery of the arranged wire cannot cover copper sheets, so that the copper-covered rate of the whole touchpad is different, the flatness of the whole touchpad can be influenced, the production yield is low, the production cost is high in the production process, and the pressure experience of a user on the touch panel is poor.
The common structure of the existing touch pad is that the uppermost layer is an RX electrode, i.e., a receiving electrode of the touch pad, the second layer is a TX electrode, i.e., a transmitting electrode of the touch pad, the third layer is an isolation laying layer for isolating the influence of a bottom touch chip and a trace on the TX/RX electrode, and the bottommost layer is a chip element and a trace layer for controlling the signal transmission and reception of the touch electrode, the communication with an upper computer, and the like.
In the application, the uppermost electrode is multiplexed, which can be an RX electrode or a TX electrode, and the uppermost electrode is relatively close to the touch surface. The specification of the present application describes in detail a case where the uppermost electrode is used as a receiving electrode and the RX electrode simultaneously supports a touch function and an NFC function, and provides a plurality of different embodiments based on the detailed description. However, these embodiments are also applicable to the case where the uppermost electrode is a transmitting electrode, and the transmitting electrode simultaneously supports the touch function and the NFC function. Fig. 1 is a schematic structural diagram of a touch pad 100.
