Abstract
An in-cell touch panel includes a first scanning line driving circuit that supplies a display driving signal to a first scanning line group among multiple scanning lines; a second scanning line driving circuit that supplies a display driving signal to a second scanning line group among the scanning lines; a touch detection circuit that detects a touch by a pointer by acquiring a detection signal from at least a subset among multiple touch detection electrodes; and a control circuit. The control circuit performs a first scanning operation to supply the display driving signal to the first scanning line group, a touch detection operation after the first scanning operation to detect the touch with the touch detection circuit, a second scanning operation to supply the display driving signal to the second scanning line group, and the touch detection operation after the second scanning operation.
