Abstract

The invention provides a touch display substrate and a touch display device. The touch display substrate comprises an underlayer substrate which comprises a display area and a lead area, multiple touch electrodes and multiple wires are arranged in the display area, the wires comprise touch electrode wires used for being connected with the touch electrodes and auxiliary wires which are not connected with the touch electrodes, at least two wires are arranged in an orthographic projection area of each touch electrode on the underlayer substrate, multiple leads are arranged in the lead area, and each wire is connected with a touch signal output end of a driving circuit through the corresponding lead. Accordingly, at least two wires are arranged in the orthographic projection area of each touchelectrode on the underlayer substrate, and then the at least two wires can be distributed in the area where the touch electrodes are located as uniform as possible, the problem that the touch electrode wire distribution is nonuniform is solved, and the display uniformity of the touch display device containing the touch display substrate is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display substrate and a touch display device. Background technique [0002] In the existing design of self-contained in-cell touch display devices, the touch electrodes are usually in the form of blocks, which are multiplexed with the common electrodes, and the touch electrodes are connected to the touch control circuit of the driving circuit through the touch electrode traces. The signal output terminal is connected, and each touch electrode corresponds to a touch electrode wiring connected thereto. During the display period, the drive circuit inputs a common voltage signal to the touch electrodes through the touch electrode wiring, and inputs a touch signal to the touch electrodes through the touch electrode wiring during the touch period. There are multiple pixel units (pixels) in the area where the touch electrodes are located. One pixel unit includes three ...
