An execution command of a context search app is received. One or more search source icons corresponding to one or more search source apps matched with the calling app is displayed on a display according to the received execution command. when one of the one or more search source icons is selected, the search result for the search source is acquired through a search source app corresponding to the selected icon. The acquired search result is displayed on the display. ## Claims ### Claim 1 A display device comprising: a display configured to display an execution screen of a calling application including a search source; and a controller configured to: receive an execution command of a context search application that provides a search result for the search source; display, on the display, one or more search source icons corresponding to one or more search source applications matched with the calling application according to the received execution command; when one of the one or more search source icons is selected, acquire the search result for the search source through a search source application corresponding to the selected icon; and display the acquired search result on the display, wherein the displayed one or more search source icons identifying the one or more search source applications are different according to the calling application being executed. ### Claim 2 (depends on 1) The display device according to claim 1, wherein the execution screen of the calling application includes one or more texts or one or more images, and wherein the search source is one of the one or more texts or one of the one or more images. ### Claim 3 (depends on 2) The display device according to claim 2, wherein, when a pointer controlled by a remote control device is located on one of the one or more texts, the controller is configured to acquire a text, on which the pointer is located, as the search source. ### Claim 4 (depends on 2) The display device according to claim 2, wherein, when a pointer controlled by a remote control is located on the search source, the controller is configured to display, on the display, an indicator indicating that the context search application is executable. ### Claim 5 (depends on 1) The display device according to claim 1, further comprising a storage configured to store a source table in which the one or more search source applications are matched to a plurality of calling applications. ### Claim 6 (depends on 5) The display device according to claim 5, wherein the controller is configured to extract the one or more search source applications matched with the plurality of calling applications by using the source table stored in the storage. ### Claim 7 (depends on 1) The display device according to claim 1, wherein the controller is configured to acquire a search result for a context search source including intent acquired according to attributes of the search source and the calling application through the search source application. ### Claim 8 (depends on 1) The display device according to claim 1, wherein the controller is configured to display the search result on one side of the selected icon in a preview form. ### Claim 9 (depends on 1) The display device according to claim 1, wherein the controller is configured to switch the execution screen of the calling application to the search result. ### Claim 10 (depends on 1) The display device according to claim 1, wherein the controller is configured to: determine whether the one or more search source applications matched with the calling application are installed on the display device; and display, on the display, only a search source icon corresponding to the search source application installed on the display device according to a determination result. ### Claim 11 (depends on 1) The display device according to claim 1, wherein the controller is configured to acquire an image of the execution screen as the search source. ### Claim 12 (depends on 1) The display device according to claim 1, wherein the controller is configured to: recognize an object included in an image of the execution screen; and acquire identification data of the recognized object as the search source. ### Claim 13 (depends on 12) The display device according to claim 12, wherein the controller is configured to receive data about the image from an auto content recognition server, and wherein the received data about the image includes identification data of the object. ### Claim 14 (depends on 13) The display device according to claim 13, wherein, when a pointer controlled by a remote control is located on the object, the controller is configured to acquire, from the data about the image, identification data of the object corresponding to coordinates at which the pointer is located. ### Claim 15 An operating method of a display device, the operating method comprising: displaying an execution screen of a calling application including a search source; receiving an execution command of a context search application that provides a search result for the search source; displaying one or more search source icons corresponding to one or more search source applications matched with the calling application according to the received execution command; when one of the one or more search source icons is selected, acquiring the search result for the search source through a search source application corresponding to the selected icon; and displaying the acquired search result on the display, wherein the displayed one or more search source icons identifying the one or more search source applications are different according to the calling application being executed.
