Abstract

The invention provides a sensor of a touch panel, which comprises a substrate, a plurality of induction electrodes, a plurality of electrostatic protection electrodes, a plurality of first bridges and a protection layer, wherein the induction electrodes, the electrostatic protection electrodes and the first bridges are arranged on the substrate; the protection layer is arranged between the induction electrodes and the first bridges and simultaneously is arranged between the electrostatic protection electrodes and the first bridges; and the protection layer is provided with a plurality of touch holes, and at least one induction electrode is electrically connected with the electrostatic protection electrodes through the touch holes and the first bridges. Electrostatic destruction energy which may be generated in subsequent touch panel assembly and touch panel usage and operation can be dispersed through the design of the electrostatic protection electrodes, then the probability that transmission lines among induction electrodes are damaged by static electricity is reduced, and the reliability of the touch panel is improved effectively. The production method of the sensor of the touch panel with an electrostatic protection function can be integrated into the production process of existing touch panels, so that extra production processes, production process cost and complexity cannot be increased.

Description

technical field [0001] The invention relates to a sensing device for a touch panel, in particular to a sensing device for a touch panel with an electrostatic protection function. Background technique [0002] The touch panel is widely used in the external port input interface of the instrument due to its characteristics of human-computer interaction and diversified design. In recent years, with the wide application of consumer electronics products, more and more products are applied with the combination of touch function and display, such as mobile phone, GPS navigator system, tablet computer (tablet PC), and notebook computer (laptop PC). [0003] Nowadays, touch panel technologies are very diverse, and the more common ones include resistive, capacitive, and optical technologies. Among them, the capacitive touch panel has become the mainstream touch technology used in mid-to-high-end consumer electronic products due to its advantages of high accuracy, multi-touch, high du...
