Driving circuit, display device including the same, and electronic device including display device

A display device comprising:

• a display component comprising pixels connected to scan lines and data lines;
• a sensor component comprising first sensors and second sensors configured to sense an external input;
• a display driver configured to divide a first clock signal of a first oscillator, generate a vertical synchronization signal, and supply a data signal to the data lines;
• a sensor driver configured to divide a second clock signal of a second oscillator, and generate a touch signal to be supplied to the first sensors and/or the second sensors;
• and
• a determination circuit configured to:
• store threshold values of a third range or threshold values of a fourth range;
• detect a cycle of the vertical synchronization signal according to a third count value of the second clock signal included in a high level section of the vertical synchronization signal, or a fourth count value of the second clock signal included in a low level section of the vertical synchronization signal;
• and
• output a detection signal when the third count value is out of the third range or the fourth count value is out of the fourth range.
