Floating touch control panel, touch control method of the same, and display device

A floating touch control panel, comprising:

• a substrate, and a modulated light source, a plurality of touch control circuits arranged in an array, a plurality of first touch control scan lines corresponding to respective rows of the plurality of touch control circuits, and a plurality of touch control read lines corresponding to respective columns of the plurality of touch control circuits, wherein the modulated light source is configured to transmit modulated light to a touch control side;
• and each of the plurality of touch control circuits comprises a touch control sub-circuit, a read sub-circuit, and an output sub-circuit, wherein:
• the touch control sub-circuit comprises an ultrasonic wave sensing unit and a light sensing unit, wherein the ultrasonic wave sensing unit is configured to transmit an ultrasonic wave to the touch control side, to convert an ultrasonic wave reflected back from the touch control side into an electric signal, and to provide a first node with the electric signal converted by the ultrasonic wave sensing unit;
• and the light sensing unit is configured to convert a modulated light reflected from the touch control side into an electric signal, and to provide the first node with the electric signal converted by the light sensing unit;
• the read sub-circuit is configured to output a touch control signal to the output sub-circuit according to a potential of the first node;
• and
• the output sub-circuit is configured to be controlled by a corresponding first touch control scan line to provide a corresponding touch control read line with a received touch control signal.
