A drive-sense module for a light emitting diode (LED) touch-sense panel includes an input source for providing a forward bias reference signal and a reverse bias reference signal, a first conversion circuit operably coupled to the input source and a second conversion circuit coupled to the input source and to an LED, where the second conversion circuit is configured to generate either a reverse bias for the LED or a forward bias for the LED based on a reverse bias reference signal or a forward bias reference signal. The drive-sense module includes a difference detection circuit to generate a signal representative of light detected by the LED in the first mode and a signal representative of light emitted by the LED in the second mode and a bi-directional dependent current source configured to output an error correction current to the first input of the difference detection circuit based on the output of the difference detection circuit.
