The common electrode signal line is connected, the driving sub-electrode is connected to the driving electrode signal line through the second via hole penetrating the first insulating layer, and an incomplete hole is formed in the insulating layer corresponding to the position of the common electrode and / or the driving sub-electrode. A half hole through the insulation.

Description

technical field [0001] The invention belongs to the technical field of display, and in particular relates to a touch substrate and a display device. Background technique [0002] There are many ways of sensing the touch screen, such as optical, microwave, resistance, capacitance and so on. Among them, capacitive induction is the most widely used. Capacitance induction type includes self-capacitance induction type and mutual capacitance induction type. Compared with self-capacitance induction type, mutual capacitance induction type has the advantages of strong anti-interference ability, high sensitivity, multi-touch and strong recognition ability, so mutual capacitance induction type has become the current The mainstream touch screen sensing method. [0003] At present, there are generally two types of mutual capacitance sensing touch screens: an in-cell touch screen and a non-in-cell touch screen. The in-cell touch screen means that the sensing electrodes and driving elec...

Problems solved by technology

[0005] The inventors have found that there are at least the following problems in the prior art: In order to avoid the time delay problem, a plurality of via holes are formed in the common electrode connection bar 100 or the insulating layer corresponding to the common electrode connection bar 100 and the common electrode 300 for common The electrode 300 is connected to the common electrode signal line 1, and the purpose of forming a plurality of via holes is to reduce the resistance of the common electrode, and each driving sub-electrode 200 only connects with the driving sub-electrode 200 through a second via hole 201 in the corresponding insulating layer. The electrode signal line 2 is connected, so for the entire touch substrate, the distribution of the via holes is very uneven, which leads to inconsistent reflective properties of the metal lines of the common electrode signal line 1 and the driving electrode signal line 2, and at the same time under the influence of the electric field Make the display of the screen uneven
