Mobile terminal, display device and method for controlling the mobile terminal

摘要

There is disclosed a mobile terminal includes a display, a plurality of NFC antennas arranged in a circumferential portion of the display to transmit and receive NFC (Near Field Communication signals, and a controller configured to receive a position of the mobile terminal on an external display device from the mobile terminal via the NFC antennas or to calculate a position of the mobile terminal on an external display device.

主权项

1. A mobile terminal comprising:
a display configured to display information; a wireless communication unit configured to transmit or receive a Near Field Communication (NFC) signal; and a controller configured to:
cause the wireless communication unit to transmit the NFC signal to an external display device or to receive the NFC signal from the external display device when the mobile terminal is placed perpendicular to and in proximity to a display screen of the external display device or when the mobile terminal is placed on the display screen of the external display device;obtain position information of the mobile terminal when the mobile terminal is placed perpendicular to and in proximity to the display screen of the external display device or when the mobile terminal is placed on the display screen of the display based on at least the NFC signal transmitted to an X-axis NFC array antenna and an Y-axis NFC array antenna of the external display device or the NFC signal received from the X-axis NFC array antenna and the Y-axis NFC array antenna of the external display device, the obtained position information including at least an X-axis position provided by the X-axis NFC array antenna or an Y-axis position provided by the Y-axis NFC array antenna;cause the wireless communication unit to:
transmit the position information to the external display device; andreceive display information corresponding to the position information from the external display device; andimplement a function according to the received display information, wherein the X-axis NFC array antenna includes a plurality of NFC antennas arranged side by side along an X-axis side edge portion of the external display device, and the Y-axis NFC array antenna includes a plurality of NFC antennas arranged side by side along an Y-axis side edge portion of the external display device.
