Abstract

A touch display substrate of a touch display device includes a pixel array, a peripheral region, at least a driving chip, a plurality of data lines, and a plurality of touch sensing read-out lines disposed in the peripheral region. Each of the touch sensing read-out lines includes a first section and a second section. The first section is electrically connected to the corresponding driving chip and the second section is electrically connected to the pixel array. The second section of at least one of the touch sensing read-out lines includes an initial point and a winding portion. The winding portion is disposed on at least one side of a vertical extending line of the initial point, the winding portion winds to and fro along a horizontal direction and along a vertical direction, and the winding portion is asymmetrical with respect to the vertical extending line of the initial point.

Claims
