Abstract: An electronic device includes: a display, a first sensor circuit, a second sensor circuit; and a processor coupled to the display, the first sensor circuit, and the second sensor circuit. Based on a change in a display driving signal of the display, the display is configured to provide, to the processor, a first synchronization signal corresponding to the changed display driving signal. Based on the first synchronization signal, a second synchronization signal different from the first synchronization signal is provided to at least one of the first sensor circuit or the second sensor circuit.

Abstract: An electronic device according to various embodiments may comprise: a display driving integrated circuit (DDIC) operably coupled to a display panel; and a touch sensor controller operably coupled to the display driving integrated circuit and operably coupled to a touch panel, wherein the display driving integrated circuit may be configured to: multiple-transmit a synchronization signal for synchronizing an operation of the display driving integrated circuit with an operation of the touch sensor controller to the touch sensor controller within one frame on the basis of a first transmission mode when the display panel is controlled on the basis of a first frame rate; and multiple-transmit the synchronization signal to the touch sensor controller within the frame on the basis of a second transmission mode when the display panel is controlled on the basis of a second frame rate. Here, time intervals between the multiple transmissions on the basis of the first transmission mode may be the same, and among time intervals between the multiple transmissions on the basis of the second transmission mode, a first time interval between a first transmission and a second transmission subsequent to the first transmission may be different from the other time intervals, except the first time interval, among the multiple transmissions on the basis of the second transmission mode.
