In an exemplary optical touch circuit and a LCD device using the same, an optical sensing unit is turned on or off according to an irradiation light intensity and accordingly generates a first signal. A first signal readout unit is electrically coupled to the optical sensing unit and turned on or off according to a first operation timing sequence and accordingly outputs the first signal. A touch reference unit is for providing a reference voltage. A second signal readout unit is turned on or off according to a second operation timing sequence and accordingly outputs the reference voltage. The touch sensing unit is electrically coupled to the first and second signal readout units and uses a voltage difference between the first signal and the reference voltage as a basis to determine that whether the optical touch circuit is touched or not.

An optical sense-control system, for receiving a first light and second light, includes a first optical filter, a second optical filter, and an optical detection module. The transmission of the first light having a majority intensity in a first wave-length band is greater than the transmission of the second light having a majority intensity in a second wave-length band in the first optical filter, the first wave-length band is less than the second wave-length band, and the transmission of the second light is greater than the transmission of the first light in the second optical filter. The optical detection module is used for creating a first control signal while the first light emitting through the first optical filter at a first zone is detected and a second control signal is created while the second light emitting through the second optical filter at a second zone is detected.
