Problems solved by technology

[0004] However, since the guard ring will occupy a considerable area of ​​the bezel area, the manufacture of the guard ring will prevent the bezel of the touch panel from being further narrowed
On the other hand, if there is no protective ring, the narrow frame cannot be equipped with electrostatic protection components to eliminate static electricity

Abstract

A touch panel can be combined together with a case assembly, the case assembly is provided with at least one conductive projection. The touch panel comprises a substrate, a frame pattern layer, a touch sensing component, a reflecting protection electrode, an electrostatic protection component, a plurality of signal connecting lines, an insulating layer, and a covering layer; wherein, the frame pattern layer is arranged on the substrate at a peripheral region; the reflecting protection electrode is overlapped with the frame pattern layer; the electrostatic protection component is connected with the touch sensing component and the reflecting protection electrode, for transferring static electricity of the touch sensing component to the reflecting protection electrode; the signal connecting lines are overlapped with the frame pattern layer and electrically connected with the touch sensing component; the covering layer has at least one contact opening exposing a part of the reflecting protection electrode, for electrically connecting the reflecting protection electrode to the conductive projection of the case assembly through the contact opening.

Description

【Technical field】 [0001] The present invention relates to a touch panel, and in particular to a touch panel for a touch display device. 【Background technique】 [0002] In recent years, touch technology has been widely used in various multimedia electronic products, especially portable mobile products, such as mobile phones, e-books, and tablet computers. Using touch technology as an input means can effectively replace the existing keyboard or mouse input methods. In addition to convenience, touch input technology has become a very popular man-machine interface and multimedia interaction method due to its intuitive operation. [0003] Generally speaking, in the manufacturing process of the touch panel, a guard ring is formed on the peripheral area of ​​the touch panel, and the guard ring is arranged outside the signal connection lines. The guard ring is usually a grounded metal line with a wide line width, so the guard ring can effectively reduce the phenomenon that the noi...
