A display device and control method thereof based on NFC function to protect privacy

Abstract

This invention discloses a display device and its control method based on NFC functionality to protect privacy. When a mobile phone is placed on a phone holder, the NFC communication module inside the holder reads this unique code and notifies the SOC via IIC to wake up the display. Simultaneously, the display wakes up the PC via the Power On function connected to the PC. After waking up the PC, the display transmits the recognized eID information to the PC via the IIC signal line. The PC compares the built-in eID information and enters the system if it is correct. When the mobile phone is removed, the NFC module fails to read the code, and the SOC controls the display to directly enter sleep mode. At the same time, it notifies the PC via the IIC channel, and the PC also enters sleep mode.
