Problems solved by technology

[0004] However, when a user uses a touch panel to operate an electronic device, electrostatic discharge (Electrostatic Discharge, ESD) is likely to occur, so that the bridge wire is easily damaged by static electricity, resulting in a gap between the two sensing pads that were originally electrically connected to each other. line break
This will cause malfunction or misjudgment of the touch panel during operation, and even cause the touch panel to be discarded

Abstract

The invention relates to a touch control panel comprising a base panel, a plurality of first bridging wires, an insulating layer, a plurality of conducting columns, a plurality of second bridging wires, a plurality of first sensing pads, a plurality of second sensing pads, a mesh electrode and a plurality of discharge electrodes, wherein the insulating layer is arranged on the base panel and covers the first bridging wires and the base panel; the conducting columns are connected between the first sensing pads and the first bridging wires; the second bridging wires, the first sensing pads, the second sensing pads, the mesh electrode and the discharge electrodes are all configured on the insulating layer; and each second bridging wire is connected between two adjacent second sensing pads; the first sensing pads and the second sensing pads are respectively positioned in grids of the mesh electrode and electrically insulated from the mesh electrode; and each discharge electrode is connected with the mesh electrode and positioned between two adjacent first sensing pads and between two adjacent second sensing pads.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to a touch panel capable of strengthening protection against electrostatic discharge (ESD). Background technique [0002] The touch panel is a common input device (input device), which can be used to control mobile phones, personal digital assistants (Personal Digital Assistant, PDA), global positioning system navigation (Global Positioning System navigation, GPS navigation) and computers, etc. electronic equipment. Generally speaking, the touch panel has a touch surface and includes a plurality of sensing pads and a plurality of bridges connecting the sensing pads. [0003] When a user touches the touch surface with a finger or a stylus and moves on the touch surface, these sensing pads can detect the position and movement of the finger or stylus on the touch surface. According to the position and movement of the finger or the stylus on the touch surface, the user can operate the elec...
