Abstract

The invention provides a touch screen and a touch electrode structure thereof, and relates to the technical field of touch. In order to solve the problems that the touch screen is poor in static tolerance, and static breakdown easily happens, the touch electrode structure comprises a substrate with the light-permeable performance. A plurality of first electrodes and a plurality of second electrodes are arranged on one face of the substrate. Each first electrode comprises a plurality of first electrode units. Each second electrode comprises a plurality of second electrode units. Every two adjacent first electrode units are connected with each other through a strip-shaped connection portion. Every two adjacent second electrode units are connected with each other through a strip-shaped bridge connection portion. All the connection portions have electrical conductivity, and the connection portions are the same as the first electrodes in material. The connection portions intersect with the bridge connection portions. Insulation layers with the light-permeable performance are arranged at the intersections and located between the connection portions and the bridge connection portions, and the connection portions are covered with the insulation layers. The width of the intersections between the connection portions and the first electrode units is larger than that of the intersections between the second electrode units and the bridge connection portions located on the second electrode units.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch electrode structure and a touch screen. Background technique [0002] With the development of display technology, touch screens are more and more widely used in display devices of various electronic products, and a touch electrode structure is arranged in the touch screen. [0003] Such as Figure 1a and Figure 1b As shown, it is a schematic diagram of an existing touch electrode structure. The touch electrode structure is arranged on a light-transmitting substrate 11, and the second electrode 13 and a light-transmitting first electrode are arranged on the substrate 11. The electrode 12 is provided with an insulating layer 14 between the first electrode 12 and the second electrode 13 . The first electrode 12 is composed of a first electrode unit 121 , and the second electrode 13 is composed of a second electrode unit 131 . Two adjacent first electrode units 121 are con...
