Abstract
There is provided a display apparatus, which includes a display configured to display a UI including a plurality of items; a sensor configured to generate electromotive force to a closed loop which is included in the display and sense a user's touch based on a change in the electromotive force which is generated in the closed loop; and a processor configured to execute a function which corresponds to an item touched by a user from among the plurality of items based on a size of the change in the electromotive force generated in the closed loop.
Claims20
A display apparatus comprising:
- a display;
- an electrode configured to provide power to the display;
- a sensor configured to:
- provide an electromotive force in a closed loop circuit included in the electrode, and
- sense a change in the electromotive force, which is provided in the closed loop circuit;
- and
- a processor configured to:
- display, on the display, a User Interface (UI) including one or more items,
- identify a touch input touching at least one item, among the one or more items, based on the sensed change in the electromotive force by the sensor, and
- execute a function which corresponds to the at least one item touched by the touch input, based on a size of the change in the electromotive force provided in the closed loop circuit.
A display apparatus comprising:
- a sensor comprising a coil configured to provide a magnetic field in accordance with an alternating current (AC) voltage applied to the coil;
- a display configured to display a User Interface (UI), the display comprising a layer provided with a closed loop circuit configured to provide an electromotive force in response to the magnetic field;
- and
- a processor configured to identify a location of a touch input based on a change in an intensity level of the electromotive force provided by the closed loop circuit corresponding to a change in distance between the coil and the layer provided with the closed loop circuit.
A controlling method of a display apparatus, the method comprising:
- displaying a User Interface (UI) including one or more items on a display of the display apparatus;
- transmitting a magnetic field to a closed loop circuit, included in an electrode configured to provide power to the display, using an inductor of a sensor, the magnetic field providing an electromotive force in the closed loop circuit;
- sensing a change in inductance of the inductor corresponding to a change in the electromotive force;
- identifying a touch input touching at least one item, among the one or more items, based on the sensed change in the electromotive force by the sensor;
- and
- executing a function corresponding to the at least one item touched by the touch input, based on a size of the change in the electromotive force provided in the closed loop circuit.
