Abstract: Disclosed is an electronic device. The electronic device according to an embodiment may include a display including a touch sensor, a fingerprint sensor formed in at least a partial area of the display, a processor and a control circuit that controls the touch sensor. The control circuit may detect an input related to an external object through the at least a partial area while the processor is in a low power state, determine whether the external object is an input related to the fingerprint sensor, when the external object is not an input related to the fingerprint sensor, discard the input of the external object, and when the external object is an input related to the fingerprint sensor, emit light through a display area at least including the at least partial area in the low power state. In addition, various embodiments understood through the disclosure may be possible.

Abstract: An electronic device includes a processor, a touch sensor, and a touch controller including a register. The processor writes, into the register, data associated with a partial area of the touch sensor specified to sense an effective touch. When the effective touch is sensed in the partial area of the touch sensor, the touch controller writes data associated with the effective touch into the register, and the processor reads the data associated with the effective touch from the register when the data associated with the effective touch is written in the register.
