Abstract: An electronic device according is provided. The electronic device includes a touch sensor, a touch sensor integrated circuit (IC) configured to identify an input position on the touch sensor, a display, and a display driving IC configured to provide, to the display, at least one driving signal for driving the display, wherein the touch sensor IC is configured to measure, based on a first schedule, the input position on the touch sensor while a first driving signal among the at least one driving signal is provided from the display driving IC in a first interval, the first schedule being configured such that the at least one driving signal does not overlap a time period of the measurement of the input position, detect, based on a change of an interval of the first driving signal from the first interval to a second interval, an event in which a time period of the first driving signal being provided at least partially overlaps the time period of the measurement of the input position, and measure the input position, based on a second schedule which is different from the first schedule.
