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.

Abstract: An electronic device according to various embodiments may include a display panel, a Display Driving Integrated Circuit (DDIC) operatively coupled to the display panel, and a processor operatively coupled to the DDIC. The DDIC may be configured to receive, from the processor, a signal indicating that a first resolution is to be converted to a second resolution while displaying an image at the first resolution through the display panel, based on a horizontal synchronization signal including a first porch interval, change a length of the porch interval in response to the reception, and display the image at the second resolution through the display panel, based on the horizontal synchronization signal including the porch interval having the changed length.

Abstract: An electronic device is provided, which includes a display, a processor configured to generate a plurality of frame images including a first frame image and a second frame image to be provided to the display, and a display driving circuit including an image processor and a memory, and configured to drive the display using the first frame image and the second frame image that are provided from the processor. The display driving circuit is configured to compare the second image frame to the first image frame, to display, through the display, a third image frame obtained through the image processor, the image processor processing the first image frame or the second image frame using an image processing scheme if the second image frame satisfies a first condition, to store the third image frame in the memory and to display the stored third image frame through the display if the second image frame satisfies a second condition.
