Abstract
A display includes a touch sensor panel, a panel controller, a case, and a signal generation circuit. The touch sensor panel includes a touch sensor. The panel controller measures a capacitance of the touch sensor. The case accommodates the display, in which at least the touch sensor panel and the panel controller are disposed. The signal generation circuit is capable of applying an AC signal to a ground of the panel controller. The case is electrically connected to the ground of the panel controller. When the signal generation circuit applies the AD signal to the ground, the panel controller measures the capacitance of the touch sensor.
