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.

Electronic device control method and electronic device

An example touch display apparatus includes a touch display panel including one or more touch areas. Each touch area can include touch structures, where each touch structure includes first touch electrodes arranged along a first direction and second touch electrodes arranged along a second direction. Each first touch electrode can include first electrode blocks arranged along the second direction. Each second touch electrode can include second electrode blocks arranged along the first direction. The display apparatus can further include at least one touch driver chip, where one touch driver chip is electrically connected to a touch signal line connected to touch structures in one touch area.
