A Doppler effect-based touch control identification device and method, and a touch screen. The touch control identification device comprises: a first transceiver module (1), used for emitting a first detection wave along a first direction, and receiving a first feedback wave formed after the first detection wave has been reflected by a touch control body; a second transceiver module (2), used for emitting a second detection wave along a second direction, and receiving a second feedback wave formed after the second detection wave has been reflected by the touch control body; a calculation module (3), used for calculating the movement speed and the movement direction of the touch control body at a touch control point according to the first detection wave, the first feedback wave, the second detection wave and the second feedback wave. A set of (two) transceiver devices are arranged, and the movement speed and the movement direction of the touch control body of the touch control point are solved by a Doppler effect-based formula, thereby achieving accurate determination of a touch control operation of the touch control body. |
