    Abstract: Disclosed is an electronic device including a display panel, an oscillator generating a clock signal, a display driving integrated circuit (DDI) generating first time information, using the clock signal, a sensor, and at least one processor identifying a variable measured by using the sensor or second time information corresponding to a reference time. The at least one processor is configured to measure a variable, using the sensor, to correct an error time between the first time information and second time information corresponding to a reference time, based on the variable, and to deliver the corrected error time or the second time information to the DDI such that the DDI corrects the first time information based on the corrected error time to display a screen of the display panel. Besides, various embodiments as understood from the specification are also possible.

    Abstract: Disclosed is an electronic device comprising at least one sensor, a communication circuit, a display, and at least one processor operationally connected to the display, wherein the at least one processor is configured to: display, on the display, a watch screen including a fixed element displayed at a designated location on the display, a repetitive element displayed on the basis of at least a designated rule, and a changing element associated with information obtained through the at least one sensor or received through the communication circuit; generate first data on the basis of at least one of the designated rule or the shape of the repetitive element; generate second data based on at least one of the fixed element or the changing element, in response to the changing element changing from a first value to a second value; and generate first deterioration information on the basis of the first data, the second data, and the duration over which the changing element maintains the first value. Various other embodiments understood through the specification are also possible.

    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.
