Abstract: An electronic device is provided. The electronic device includes a display panel on which a plurality of pixels are arranged, first group lines providing a source voltage to each of the plurality of pixels, a display driver integrated circuit that includes a plurality of source amplifiers electrically connected with the first group lines and providing the source voltage to each of the plurality of pixels, at least one sensing line crossing the first group lines, and first group switches disposed on the at least one sensing line, and a sensing circuit electrically connected with one end of the at least one sensing line to check a crack in at least a partial region of the electronic device. The display driver integrated circuit receives a specified signal for the electronic device to enter a sense mode, applies a first voltage to the other end of the at least one sensing line that is distinguished from the one end of the at least one sensing line, in response to the received specified signal, turns on the first group switches such that the at least one sensing line is short-circuited from the other end of the at least one sensing line to the sensing circuit, obtains a second voltage sensed by the sensing circuit electrically connected with the one end of the at least one sensing line, and checks information regarding the crack in the at least partial region of the electronic device based on a difference between the first voltage and the second voltage. In addition to the above, various embodiments identified through the specification are possible.
