Abstract:
Disclosed floating touch control panel includes a substrate, a modulated light source, a read sub-circuit, an output sub-circuit, an ultrasonic wave sensing unit and a light sensing unit; the ultrasonic wave sensing unit is configured to transmit an ultrasonic wave to a touch control side, to convert an ultrasonic wave reflected back from the touch control side into an electric signal and then provide it to a first node; the light sensing unit is configured to convert a modulated light reflected from the touch control side into an electric signal and then provide it to the first node; 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; the output sub-circuit is configured to be controlled by a corresponding first touch control scan line to provide a touch control read line with the received touch control signal.
