    Abstract: A display apparatus is provided. The display apparatus includes a display and a controller. The display is configured to display an image and comprises a touch sensor for touch input within an assigned sensing section. The controller is configured to perform an operation corresponding to the touch input sensed within the sensing section, and to control the touch sensor to adjust the sensing section based on conditions for adjusting the sensing section. With this, the display apparatus and a control method thereof which can efficiently sense, without lowering the speed of sensing, a touch input based on a plurality of pens or fingers is provided.

    Abstract: 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.

    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.
