Problems solved by technology

However, the pattern of the existing ground electrode is similar to a loop antenna, and the loop antenna will convert the electrical signal in the circuit and the electromagnetic energy in the space. Therefore, when the electronic product is in operation, the ground electrode is easy to cause damage to the internal circuit. signal interference, causing unwanted noise

Abstract

The utility model provides a touch panel. The touch panel comprises a substrate, a touch sensing element, a plurality of wires and a grounding electrode. The substrate comprises a displaying area and a peripheral area adjacent to the displaying area. The touch sensing element is arranged on the substrate and at least located in the displaying area. The wires are located on the substrate and in the peripheral area and electrically connected with the touch sensing element. The grounding electrode is arranged on the substrate and in the peripheral area. The grounding electrode comprises a plurality of segments separated from one another.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to a touch panel which improves signal interference. Background technique [0002] Generally speaking, electronic products may be damaged by electrostatic discharge at any time during production, packaging, testing, handling, and final assembly and use, resulting in the possibility of malfunctioning. Therefore, electronic products must have electrostatic discharge protection design in order to effectively improve the damage to the life of electronic products caused by electrostatic discharge. [0003] During the manufacturing process, a ground electrode is usually formed around the internal circuit to guide the current generated by electrostatic discharge to the ground terminal, and prevent the internal circuit from being damaged due to the current flowing into the internal circuit. However, the pattern of the existing ground electrode is similar to a loop antenna, and the loop antenna ...
