1. A display apparatus comprising:
- a display panel which comprises a light emitting device;
a sensor which senses an electric current flowing in the light emitting device; and
a controller which controls the display panel to display user interface (UI) information on a predetermined region of the display panel to induce and receive an external stimulus at the predetermined region of the display panel according to the displayed UI information, determines that the external stimulus occurs to the display panel if a change of the sensed electric current flowing in the light emitting device exceeds a preset current change rate, and performs an operation based on a determination result,wherein the light emitting device comprises an organic light emitting material,wherein while the UI information is displayed, the controller prevents supplying electric current flows to the light emitting device of another region of the display panel where the UI information is not displayed so that the controller does not determine the external stimulus on the another region.

10. A display apparatus comprising:
-
a display panel which comprises an organic light emitting diode; and a controller which controls the display panel to display user interface (UI) information on a predetermined region of the display panel to induce and receive an external stimulus at the predetermined region of the display panel according to the displayed UI information and determines that the external stimulus occurs to the display panel if a threshold voltage of the organic light emitting diode is changed in response to a change in temperature of the display panel, wherein the organic light emitting diode comprises an organic light emitting material, and wherein while the UI information is displayed, the controller prevents supplying electric current flows to the light emitting device of another region of the display panel where the UI information is not displayed so that the controller does not determine the external stimulus on the another region.

11. A display apparatus comprising:
-
a display panel which comprises a light emitting device; a sensor which senses an electric current flowing in the light emitting device at a predetermined region of the display panel; and a controller which controls the display panel to display user interface (UI) information on the predetermined region of the display panel to induce and receive an external stimulus at the predetermined region of the display panel according to the displayed UI information and performs an operation if a change of the sensed electric current at the predetermined region exceeds a preset current change rate, wherein the light emitting device comprises an organic light emitting material, and wherein while the UI information is displayed, the controller prevents supplying electric current flows to the light emitting device of another region of the display panel where the UI information is not displayed so that the controller does not determine the external stimulus on the another region.

12. A display apparatus comprising:
-
a display panel which comprises a light emitting device and a light emitting region divided into a plurality of sub-regions; a plurality of sensors which sense an electric current flowing in each of the plurality of sub-regions; and a controller which determines that an external stimulus occurs to at least one of the plurality of sub-regions if a change of the sensed electric current in the at least one of the plurality of sub-regions exceeds a preset current change rate and performs an operation, and the controller further controls the display panel to display user interface (UI) information on at least one predetermined sub-region of the plurality of sub-regions of the display panel to induce and receive a user stimulus at the at least one predetermined sub-region according to the displayed UI information, wherein the light emitting device comprises an organic light emitting material, and wherein while the UI information is displayed, the controller prevents supplying electric current flows to the light emitting device of another region of the display panel where the UI information is not displayed so that the controller does not determine the external stimulus on the another region.

13. A method of controlling a display apparatus with a display panel comprising a light emitting device, the method comprising:
-
displaying user interface (UI) information on a predetermined region of the display panel to induce and receive an external stimulus at the predetermined region of the display panel according to the displayed UI information; sensing an electric current flowing in the light emitting device; determining that the display panel receives the external stimulus at the predetermined region of the display panel if a change of the sensed electric current exceeds a preset current change rate; and performing an operation based on a determination result, wherein the light emitting device comprises an organic light emitting material, and wherein while the UI information is displayed, the supply of electric current flows to the light emitting device of another region of the display panel where the UI information is not displayed is prevented, so that the external stimulus on the another region is not determined. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
