Touch module and driving method therefor, and touch display device

A touch display device, comprising a display panel, a touch module, and a drive chip for driving the display panel and the touch module, the drive chip being connected with the data selection lines;

• wherein the touch module comprises a touch area and a non-touch area, touch signal lines extending from the touch area to the non-touch area and n data selection circuits connected with the touch signal lines;
• each data selection circuit is connected with m touch control signal lines, m and n are positive integers, and m is greater than or equal to 2;
• and each data selection circuit comprises m switching transistors and a data selection line, wherein the switching transistors are in one-to-one correspondence to the touch signal lines, a control terminal of each switching transistor is connected with a level signal line providing time-division drive level signals, a first terminal of each switching transistor is connected with corresponding touch signal line, and a second terminal of each switching transistor is connected with the data selection line;
• and
• the touch display device further comprises a flexible printed circuit board, the data selection circuits and the drive chip are located in a bezel area of the display panel;
• and the touch signal lines are connected with the first terminals of the switching transistors in the data selection circuits through the flexible printed circuit board.
