Abstract

The invention relates to an NFC coil driving device, a method and electronic equipment. The NFC coil driving device includes an NFC coil and a display driving chip. The NFC coil is connected to a display driver chip, and the NFC coil is used for data transmission; the display driver chip is provided with an NFC driver module, and the display driver chip is used to receive NFC drive signals, and generate clock pulses according to the NFC drive signals The signal, through the NFC driver module, converts the clock pulse signal into a corresponding frequency and outputs it to the NFC coil, and drives the NFC coil for data transmission. By setting a simple NFC driver module in the display driver chip, it is possible to drive the NFC coil for data transmission through the display driver chip, as long as the clock signal can be converted into the corresponding frequency, it is easy to drive the NFC coil for data transmission , and the size of the display driver chip is small, and there is no additional NFC module, which reduces the space occupied by the NFC module.

Description

technical field [0001] The invention relates to the technical field of near field communication, in particular to an NFC coil driving device, method and electronic equipment. Background technique [0002] NFC (Near Field Communication) is the abbreviation of near-field communication. It is a short-distance high-frequency wireless communication technology. By transmitting a radio frequency field and matching the field frequency with another device, data can be read and written between the two. Allowing non-contact point-to-point data transmission between electronic devices is a process of data transmission. This technology has evolved from contactless radio frequency identification (RFID). The near-field communication service combines near-field communication technology and mobile communication technology to realize various functions such as electronic payment, identity authentication, ticketing, data exchange, anti-counterfeiting, and advertisement, and is a new type of serv...
