Touch display device and touch display substrate thereof

A touch display substrate, comprising:

• a pixel array;
• a peripheral region, disposed around the pixel array;
• at least a driving chip, disposed in the peripheral region;
• a plurality of data lines, disposed in the peripheral region, wherein each of the data lines includes a first section and a second section, the first section of each of the data lines is electrically connected to the driving chip, the second section of each of the data lines is electrically connected to the pixel array with a connection node, and the connection nodes of any two neighboring second sections of the data lines have an equal distance;
• and
• a plurality of touch sensing read-out lines, disposed in the peripheral region, wherein each of the touch sensing read-out lines includes a first section and a second section, the first section of each of the touch sensing read-out lines is electrically connected to the corresponding driving chip, and the second section of each of the touch sensing read-out lines is electrically connected to the pixel array;
• wherein the second section of at least one of the touch sensing read-out lines includes an initial point and a winding segment, the winding segment is disposed on at least one side of a vertical extending line of the initial point, winds to and fro along a horizontal direction and a vertical direction, and is asymmetrical with respect to the vertical extending line of the initial point.
