Abstract:
The present application discloses a sensing screen, a control circuit and control method thereof, and a sensing screen apparatus. The sensing screen includes a display screen, a first transparent medium layer, a transparent connection layer, and an antenna layer. The antenna layer includes multiple antenna units, and the antenna units include at least one first antenna unit and multiple second antenna units. The first antenna unit is configured to transmit a sensing signal, the second antenna units are configured to receive reflected signals of the sensing signal, and the reflected signals are generated by a touch object by reflecting the sensing signal. According to the present application, the antenna layer is arranged right above the display screen, so that a touch area of the sensing screen is fully utilized while screen display is not affected, so as to substantially increase an antenna size and increase an antenna gain.
