Abstract
A controlling method, adapted for an electronic device for coexistence of radio frequency identification (RFID) and display functions, is provided. The controlling method includes powering on a display of the electronic device and controlling the display to show a frame. Next, a RFID module of the electronic device is powered on to perform a wireless communication function of the RFID module. The controlling method of the invention efficiently controls the execution of the display and wireless communication functions, so as to prevent mutual interference.
Claims9
A controlling method for coexistence of radio frequency identification (RFID) and display functions, applicable to an electronic device, the controlling method comprising:
- determining whether the electronic device executes a first integration mode or a second integration mode;
- powering on a display of the electronic device;
- controlling the display to show a frame;
- powering on a RFID module of the electronic device;
- and
- executing a wireless communication function of the RFID module, wherein the first integration mode is an integration of a display mode and an error detection mode,
- wherein if the electronic device executes the first integration mode, the step of executing the wireless communication function of the RFID module comprises:
- reading a product history recorded in a RFID label of the electronic device, and the powering on of the display is ceased after the product history has been read, and
- wherein the display of the electronic device is an electrophoretic display (EPD), and the electronic device is an electronic shelf label (ESL).
