| description | The invention discloses a double-layer touchpad and a control method of an NFC (Near Field Communication) function thereof, relates to the technical field of touch electronic products, and solves the technical problem that the existing touchpad is difficult to reduce the power consumption of equipment while reducing the manufacturing cost. The touchpad comprises a touch layer, a device layer, a touch chip, an NFC (near field communication) chip, an NFC antenna and a master control connecting port, wherein the touch layer and the device layer are stacked; the touch control chip is respectively connected with the main control connection port and the NFC chip; the NFC antenna is connected with the NFC chip; and the touch chip is used for acquiring a capacitance signal of the touch layer and controlling the NFC chip. According to the touch panel, interference of NFC signals on touch scanning can be avoided by adopting a double-layer panel design, the burden of a main control end is reduced, the reaction time is s |
