In the traditioanl contactless application market, the device usually attach the antenna to the back side or side face of the device. That's not friendly for user experience and the device industrial design, since the designer has to reserve a large space for antenna intigration. Thus the device is very unwieldy and uncomfortable for user. To solve this problem, we investigate how to integate the antenna into display, and user can use contactless card directly from the surface of display. At the same time, the whole device can be much more small and exquizite, and easy to carry. That help a lot in the industrial design for the whole device. And the screen‐to‐body ratial is improved significantly. The key tech is to optimize the TFT routing layout and ultilize a special ferrite plate to enhense the inductance and Q‐factor of antenna.
