Abstract
A thin-film transistor displayer integrated with an NFC antenna, is a TP on/in cell thin-film transistor displayer. The NFC antenna is arranged on a display screen of the thin-film transistor displayer, where the NFC interface is built in an output circuit of the display screen and connected to a control mainboard of the display screen. The display screen and NFC antenna features are combined into one, and the NFC antenna is arranged directly on the thin-film transistor displayer, avoiding problems 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 and touch panel of the displayer, or for the case that the NFC signal must be received from the display panel and touch panel of the displayer.
