Abstract
A touch screen device, an input device, and a control method thereof are provided. The touch screen device includes a channel electrode configured to receive a signal from an input device, a driver circuit configured to apply a drive signal to the channel electrode, a receiver circuit configured to receive the signal from the channel electrode, and a processor configured to control the driver to transmit an input device identification information to the input device such that, when a signal transmitted from the input device is received through the receiver circuit, based on a frequency of the received signal or a pattern of the received signal, the processor determines if the received signal is associated with the input device identification information transmitted to the input device. Accordingly, a touch screen device capable of touch inputting with respect to a plurality of input devices can be provided.
