Abstract

The present invention provides a touch display substrate and a touch display device. The touch display substrate includes: a base substrate, the base substrate includes a display area and a lead area, and a plurality of touch electrodes and a plurality of wires are arranged in the display area. The wiring includes the touch electrode wiring used to connect to the corresponding touch electrode and the auxiliary wiring not connected to the touch electrode, and each touch electrode is provided with at least two There are multiple wires arranged in the wire area, and each wire is connected to the touch signal output terminal on the driving circuit through the wire. In the present invention, each touch electrode is provided with at least two traces in the orthographic projection area on the substrate, so that the at least two traces can be distributed as evenly as possible in the area where the touch electrodes are located, The problem of uneven distribution of traces of the touch electrodes is improved to improve the display uniformity of the touch display device including the touch display substrate.

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 ...
