Abstract
Provided are a touch display screen and a driving method therefor, and a display apparatus. A common electrode layer is divided into a plurality of mutually independent self-capacitance electrodes, and the self-capacitance electrodes are connected to a driving chip via corresponding touch-control traces; and each self-capacitance electrode is connected to a common voltage line via a switching transistor, and a gate electrode of each switching transistor is connected to a control line.
