Abstract: A touch panel control circuit includes a switch signal generation circuit, a touch panel drive signal generation circuit that generates a touch panel drive signal, and a synchronizing signal generation circuit. The switch signal generation circuit generates a switch signal corresponding to a generation timing of the touch panel drive signal. The switch signal specifies a switching period during which a switching liquid crystal drive signal driving a switching liquid crystal panel is switched to a touch panel drive signal and supplied to a common board that is commonly used for a touch panel and a switching liquid crystal panel. The synchronizing signal generation circuit generates a synchronizing signal that starts switching from the switching liquid crystal drive signal to the touch panel drive signal at a predetermined period.

Abstract: Provided is a display device with a touch sensor that can avoid the influence of noise originating from the polarity inversion of a common voltage of the display device without using special circuitry. The display device with a touch sensor includes a sensor output readout circuit (21) that is sequentially connected to multiple sensor electrodes in a touch sensor unit (7) and outputs signal voltages that correspond to the electrical characteristics of the electrodes, a sensor control circuit (23) that supplies a control signal to the sensor output readout circuit (21), and a coordinate computation circuit (22) that detects a contact position based on the signal voltages. The sensor control circuit (23) causes a scan operation, in which the sensor output readout circuit (21) is sequentially connected to all of the sensor electrodes of the touch sensor unit (7) and outputs the signal voltages, to start after the common voltage has switched from a first polarity to a second polarity, and to end before the common voltage returns to the first polarity.
