Abstract
A semiconductor device includes an analog front end and processing circuitry. The analog front end is configured to obtain capacitance detection data depending on capacitances of a plurality of sense electrodes of a liquid crystal display panel. The processing circuitry is configured to generate touch sensing data associated with a current touch sensing frame, based on capacitance detection data associated with the current touch sensing frame and capacitance detection data associated with a former touch sensing frame selected in response to a state in which the liquid crystal display panel is placed in the current touch sensing frame.
