Abstract
An electronic device control method is provided. The method may be applied to an electronic device having a touchscreen. A display drive circuit and a touch sensor that match the touchscreen are configured in the electronic device. The method includes: The display drive circuit performs pixel scan. The touch sensor collects a touch signal once after the display drive circuit scans S rows of pixels each time, where S≥1. Touch signals collected N consecutive times are used as one group. An uplink synchronization signal is transmitted to the outside in a slot for collecting a touch signal for the Ktime in each group, where 1≤K≤N. The uplink synchronization signal is used to perform time alignment with an external device.
