    摘要： 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.

    摘要： A display apparatus capable of being touched plural times by a single user or being used by a plurality of users is provided. The display apparatus includes: a display; a sensor sensing a user touch on the display; and a processor configured to execute a writing function corresponding to a first touch when the first touch is sensed through the sensor and executing a function corresponding to a second touch of a user at a coordinate value at which the second touch is sensed in response to the second touch when the second touch is sensed in a predetermined range of the first touch based on a coordinate value at which the first touch is sensed during a period in which the first touch is input.
