Abstract: Embodiments of the present disclosure provide a method for controlling a flexible capacitive touch display panel and a corresponding touch display apparatus. The capacitive touch display panel is provided with a plurality of signal lines arranged in a grid shape, and a signal line extending in a first direction and a signal line extending in a second direction are electrically insulated from each other. In this method, for each of the plurality of signal lines, a drive signal is applied to the signal line as a drive signal line. An induction signal is received from a signal line parallel to and adjacent to the drive signal line as an induction signal line. If an intensity of the induction signal is increased, it is determined that the capacitive touch display panel is bent at a bending location between the drive signal line and the induction signal line.
