Document Type and Number:
WIPO Patent Application WO/2023/103501
Kind Code:
A1
Abstract:
Disclosed in the present application is a laptop computer. The laptop computer is provided with a touch-control panel for a user to perform a touch-control operation. The touch-control panel comprises: a touch-control electrode module and a control module, wherein the touch-control electrode module is electrically connected to the control module, and the touch-control electrode module comprises a receiving electrode and a transmitting electrode; the receiving electrode is insulated from the transmitting electrode, and the receiving electrode and the transmitting electrode each comprise a plurality of electrodes; when the control module acquires a near field communication (NFC) signal, the control module connects the plurality of electrodes of the receiving electrode or the transmitting electrode into a receiving coil configuration or a transmitting coil configuration; and after NFC is completed, the receiving electrode and the transmitting electrode form a touch-control matrix which is capable of detecting touch coordinates. According to the present application, an NFC signal can be received and sent by means of electrodes sharing a control module, thereby improving the recognition efficiency of the NFC signal, improving the reliability, and further improving the user experience. In addition, further provided in the present application are a signal processing method and an NFC system.
