Abstract
A touch display panel, a method for driving the same, and a display device. The touch display panel includes: an array substrate including pixel zones in an array, control signal lines at gaps between rows of pixel zones, and acquisition signal lines at gaps between columns of pixel zones, and insulated from control signal lines, sub-pixels, line recognition control transistors, and line recognition electrodes at gaps between the sub-pixels are arranged in pixel zones; line recognition control transistors have gates connected the control signal line, sources connected with line recognition electrodes, and drains connected with acquisition signal line; control signal lines provide line recognition control transistors with a control signal; and the acquisition signal lines provide the line recognition electrodes with a line recognition signal through the line recognition control transistors, and receive a signal carrying line information transmitted by the line recognition electrodes through the line recognition control transistors.
