Abstract

The invention discloses a touch panel. The touch panel comprises a substrate, a touch sensing array, a first electrostatic protection circuit, a first insulation layer and a plurality of first connecting lines. The substrate is provided with an active area and a peripheral area surrounding the active area. The touch sensing array is arranged on the substrate and located in the active area. The first electrostatic protection circuit is arranged on the substrate and located in the peripheral area. The first insulation layer is arranged on the substrate and located in the peripheral area. The first electrostatic protection circuit is covered with the first insulation layer. The first connecting lines are arranged on the first insulation layer and are coupled to the touch sensing array.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to a touch panel with electrostatic protection function. Background technique [0002] In recent years, with the rapid development and application of information technology, wireless mobile communications and information home appliances, many information products have been replaced by traditional input devices such as keyboards or mice in order to achieve more convenience, smaller size and more humanization. Switch to using a touch panel (Touch Panel) as an input device. [0003] Touch panels can be roughly classified into resistive touch panels, capacitive touch panels, optical touch panels, acoustic wave touch panels, and electromagnetic touch panels according to different sensing modes. Compared with other types of touch panels, the capacitive touch panel has the advantages of fast response time, good reliability and high definition, so it is widely used in various handheld electroni...
