Abstract
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.
