Abstract

The invention discloses a touch panel and a making method thereof and a touch device, and the touch panel and the touch device are used for reducing the electrostatic breakdown phenomenon. The touch panel comprises a first electrode, a second electrode, a grounding line located in a non-touch area and at least one group of mutually insulated electrostatic guide lines which are arranged between the first electrode and the second electrode; the first electrode and the second electrode are located on the same layer in a touch area and arranged in a mutually crossed mode; the first electrode comprises multiple first sub electrode blocks which are arranged in the first direction, the second electrode comprises multiple second sub electrode blocks which are arranged in the second direction, every two adjacent second sub electrode blocks are connected with each other in the second direction, every two adjacent first sub electrode blocks are connected in a bridged mode through a connection bridge in the first direction, and the first direction is perpendicular to the second direction; each group of the electrostatic guide lines walk along gaps between every two adjacent first sub electrode block and second electrode block in the touch area and pass through at least one bridge connection area and are conductive with the grounding line in the non-touch area.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch panel, a manufacturing method thereof, and a touch device. Background technique [0002] A liquid crystal display is a commonly used flat panel display at present, and a thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD for short) is a mainstream product in the liquid crystal display. [0003] Electrostatic breakdown is a very common damage mode in the electronics industry. It is a phenomenon caused by electrostatic discharge of a large amount of static electricity concentrated to a certain part of the device. Electrostatic breakdown will cause very serious damage to TFT-LCD devices, and it needs to be avoided as much as possible during the manufacturing process of TFT-LCD devices. [0004] The wiring of the capacitive touch panel includes a plurality of sensing electrode layers arranged in parallel at intervals, a plurality...
