Abstract
The present invention relates to near field communication technology. Specifically, disclosed is an electrophoretic display device having integrated an NFC antenna. The NFC antenna is arranged on a display screen of the electrophoretic display device, where the NFC interface is equipped with an output circuit of the display screen and is connected to a control mainboard of the display screen. The present invention combines the display screen and NFC antenna features into one, and has the NFC antenna provided directly on the electrophoretic display device, thus preventing the problem of signal quality deterioration and reception failure due to wearing of the NFC antenna interface and inaccurate alignment. In addition, a solution is provided for facilitating reception of an NFC signal from a display panel of the display device or for when the NFC signal must be received from the display panel of the display device.
