The at least one processor is configured to acquire, in a state in which at least one portion of the display is exposed to the front surface of the electronic device, data indicating a capacitance change on the at least one portion of the display through the touch sensor panel, identify a moisture-introduced state, based on the acquired data, and perform an operation of responding to the identified moisture-introduced state. ## Claims ### Claim 1 An electronic device, comprising: a housing; a display including a touch sensor panel, wherein the display is configured to move with respect to the housing so that at least one portion of the display is exposed from an inside of the housing to a front surface of the electronic device or is inserted into the inside of the housing; and at least one processor operatively connected to the display, wherein the at least one processor is configured to: acquire, in a state in which the at least one portion of the display is exposed from the inside of the housing to the front surface of the electronic device, data indicating a capacitance change on the at least one portion of the display through the touch sensor panel, identify a moisture area on the at least one portion of the display, based on the acquired data, and in response to identifying the moisture area on the at least one portion of the display, perform an operation according to a size of the moisture area on the at least one portion of the display or a position of the moisture area on the at least one portion of the display in order to prevent the moisture from being introduced into the electronic device, wherein, if the size of the moisture area on the at least one portion of the display is larger than or equal to a threshold or the position of the moisture area on the at least one portion of the display is adjacent to a portion of the housing within a predetermined distance, the operation is for limiting the at least one portion of the display to be inserted into the housing, and wherein, if the size of the moisture area on the at least one portion of the display is less than the threshold or the position of the moisture area on the at least one portion of the display is farther apart from the portion of the housing than the predetermined distance, the operation is for displaying a notification indicating that the moisture should be removed through the display. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the display is configured to move through rolling or sliding with respect to the housing so that at least one portion of the display is exposed from the inside of the housing to the front surface of the electronic device. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the at least one processor is configured to stop a rolling or sliding operation which, in response to a case in which the size of the moisture area is larger than or equal to the predetermined area or the position of the moisture area is adjacent to the portion of the housing within the predetermined distance, causes the at least one portion of the display to be inserted into the housing. ### Claim 4 (depends on 3) The electronic device of claim 3, wherein the at least one processor is configured to: identify the size of the moisture area or the position of the moisture area while the rolling or sliding operation is stopped, and release the stopping of the rolling or sliding operation, in response to a case in which the size of the moisture area is smaller than the threshold or the position of the moisture area is farther apart from the portion of the housing than the predetermined distance. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the at least one processor is configured to turn off power of the electronic device based on the size of the moisture area being larger than or equal to the threshold. ### Claim 6 (depends on 5) The electronic device of claim 5, wherein the at least one processor is configured to: identify the size of the moisture area before rebooting, while the power of the electronic device is turned off, and complete the rebooting, based on the identified size of the moisture area being smaller than the threshold. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the at least one processor is configured to: sense moisture introduced into a connector, and based on the moisture introduced into the connector being sensed, identify the moisture-introduced state. ### Claim 8 A method performed by an electronic device to sense introduction of moisture, the method comprising: acquiring, in a state in which at least one portion of a display of the electronic device is exposed from an inside of a housing of the electronic device to a front surface of the electronic device, data indicating a capacitance change on the at least one portion of the display through a touch sensor panel of the electronic device, wherein the display is configured to move with respect to the housing so that at least one portion of the display is exposed from the inside of the housing to the front surface of the electronic device or is inserted into the inside of the housing;
