Touch display panel and display device
A touch display panel includes: a base substrate provided with multiple gate lines and data lines which are insulated from and intersecting with each other to define multiple sub-pixels; a common electrode layer, formed by multiple self-capacitance electrodes arranged in an M*N array; a drive integrated circuit; and multiple touch detection signal lines; at least three adjacent columns of sub-pixels constitute a pixel column, each column of sub-pixels is parallel to an extending direction of the data line; the touch detection signal line is located between two adjacent columns of sub-pixels, the multiple touch detection signal lines connects the self-capacitance electrode with the drive integrated circuit, at least part of two adjacent pixel columns is not provided with the touch detection signal line therebetween; the drive integrated circuit provides common signal or touch detection signal to the touch detection signal line in display stage or touch stage, respectively.
