US 9,543,637 B2 · Thin-film transistor display device having integrated NFC antenna

Abstract

A thin-film transistor display device having integrated an NFC antenna (3). The NFC antenna (3) is arranged on a display screen (S) of the thin-film transistor display device, where the NFC interface is equipped with an output circuit of the display screen (S) and is connected to a control mainboard of the display screen (S). The thin-film transistor display device combines the display screen (S) and NFC antenna (3) features, and has the NFC antenna (3) provided directly on the thin-film transistor display device, thus preventing the problem of signal quality deterioration and reception failure due to wearing of the NFC antenna interface and inaccurate alignment, while facilitating reception and transmission of signals by the antenna, thus ensuring the smoothness of communication.
