Abstract: A driving circuit includes: a display driver to generate a horizontal synchronization signal and a vertical synchronization signal according to a first clock signal of a first oscillator; a sensor driver to generate a touch signal according to a second clock signal of a second oscillator; and a determination circuit to detect a cycle of at least one of the horizontal synchronization signal or the vertical synchronization signal according to the second clock signal, and output a detection signal when the cycle is out of a range. The determination circuit is a part of the display driver or the sensor driver.

Abstract: A display device includes a display unit including pixels. A sensor unit overlaps with the display unit and includes sensors. A sensor driver transmits a driving signal to the sensors, and receives sensing signals corresponding to the driving signal from the sensors. One sensing period includes a first sensing period and a second period. The sensor driver transmits a first driving signal having a first frequency to the sensors in the first sensing period, and transmits a second driving signal having a second frequency different from the first frequency to the sensors in the second sensing period.
