Abstract:
The present disclosure relates to a display device. The display device includes a display module and a sensing circuit board including a plurality of sensing dots disposed on the display module and generating a magnetic field. Each of the sensing dots includes continuous first and second periods. Additionally or alternatively, the sensing dots includes a transmitter, a driver, a charger, and an outputter. The transmitter transmits a reference alternating current signal. The driver is connected to the transmitter and a sensing node and outputs a node current signal. The charger is connected to the sensing node and generates a magnetic field. The outputter is electrically connected to an output terminal and outputs a sensing signal.
