Abstract:
A drive circuit of an in cell type touch panel includes a thin film transistor that controls whether to pass a signal to drive a counter electrode when a finger touches and a thin film transistor that controls whether to pass a counter electrode voltage in display. The drive circuit raises a gate voltage applied to the thin film transistor when the drive signal is passed more than a gate voltage applied to the thin film transistor when the counter electrode voltage is passed.
