Title: PANEL DRIVING DEVICE AND PANEL DRIVING METHOD
Abstract:
The present invention provides a panel driving device: supplying a first signal to a first sensor electrode by using a first amplifier, so as to detect a change in the capacitance of the first sensor electrode; supplying a second signal, having the same waveform as that of the first signal, to a second sensor electrode adjacent to the first sensor electrode by using a second amplifier; and detecting the proximity or a touch of an external object toward the sensor electrodes according to the change in the capacitance of the first sensor electrode.
