A kind of substrate, touch screen and touch display device

Abstract

The invention discloses a substrate, a touch screen and a touch display device, relates to the technical field of touch display, and aims to improve the anti-interference and anti-static capabilities of the touch screen. The substrate includes a functional area and a peripheral area, the peripheral area is provided with a first wiring and a second wiring insulated from each other, the first wiring and the second wiring are respectively grounded, and the first wiring and the second wiring are respectively It is connected with the circuit board to form a ground wire conduction loop; the first wiring and the second wiring have multiple crossing points. The touch screen includes the above-mentioned substrate, and the substrate is arranged on the periphery of the touch screen traces of the touch screen. The substrate provided by the invention is used in a touch display device.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to a substrate, a touch screen and a touch display device. Background technique [0002] The touch screen is an intelligent human-computer interaction interface product, which has been widely used in many display devices, and the integrated touch (One Glass Solution, abbreviated as OGS) touch screen is an important branch of the touch screen; this OGS In the display device, the touch screen can not only function as a touch sensor, but also can protect the display device. Therefore, the OGS touch screen has received great attention. [0003] At present, when the OGS touch screen is produced, not only an ITO conductive film and a touch sensor will be formed on a glass plate; moreover, in order to discharge the static electricity released in the OGS touch screen, a ground wire conduction loop will be set on the ITO conductive film of the OGS touch screen . However, since the co...

Problems solved by technology

However, since the conduction loop of the ground wire is composed of two conductive ground wires, the two ground wires are easily affected by the antenna effect, and generate currents with different sizes and the same direction, so that the conduction loop of the ground wire will generate an interference current Therefore, in order to avoid the influence of interference current on the ground wire, the two ground wires are generally interrupted to effectively avoid the influence of the antenna effect on the ground wire, but this also greatly reduces the anti-static ability of the OGS touch screen
