An electronic device capable of wireless charging for a pen-type input device includes a display, a touch panel coupled to the display and having a plurality of sides facing in different directions, a conductive trace connected to the touch panel to receive a touch signal detected on the touch panel, and a wireless charging pad configured to wirelessly transmit power to the pen-type input device and disposed adjacent to one side of the plurality of sides of the touch panel, and the conductive trace is disposed on another side of the plurality of sides of the touch panel, the another side of the touch panel being opposite to the one side of the touch panel.

Electronic device capable of wireless charging

An electronic device includes a touch sensor integrated circuit (IC) and a display driver IC. The display driver IC is configured to: obtain information for a display update, and provide, to the touch sensor IC, a first driving signal including (i) a first pulse indicating an address scan period in which the information is recorded via application of a voltage and (ii) a second pulse indicating a self-scan period in which the recorded information is maintained without application of the voltage. Furthermore, while the first driving signal is provided from the display driver IC, the touch sensor IC is configured to: perform a first operation based on detection of the first pulse, and perform a second operation based on detection of the second pulse.

Electronic device and method for controlling touch function

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.
