AI Technical Summary

Problems solved by technology

However, in the existing via hole design, undercut may occur due to lateral etching, thereby causing the risk of peeling of the film layer, or the film may be damaged due to under-etching. The gas generated between the layers cannot be discharged, which will cause bubbles between the layers of the film
In this way, it may cause a short circuit or an open circuit, which will eventually lead to low yield and poor product reliability.

Abstract

An electronic component comprises a substrate, a signal line, a first insulating layer, a first electrode, a second insulating layer and a second electrode. The signal line is arranged on the substrate. The first insulating layer is arranged on the signal line. The first electrode is arranged on the first insulating layer. The second insulating layer is arranged on the first electrode and the first insulating layer. The second electrode is arranged on the second insulating layer. The second insulating layer has a first through hole, and the first insulating layer and the second insulating layer share a second through hole. The signal line is electrically connected with the first electrode by means of the first through hole, the second through hole and the second electrode.

Description

technical field [0001] The present invention relates to a component, and in particular to an electronic component. Background technique [0002] In recent years, in order to achieve more convenience, smaller size and more humanization, many information products have changed from traditional input devices such as keyboards or mice to use touch panels as input devices, which have both touch and display functions. Functional touch display devices have become one of the most popular products today. According to different structures and manufacturing methods, touch display devices can be roughly divided into three types: out-cell, on-cell and in-cell. [0003] During the manufacturing process of the in-cell touch display device, an etching process is required to form through holes. However, in the existing via hole design, undercut may occur due to lateral etching, thereby causing the risk of peeling of the film layer, or the film may be damaged due to under-etching. The gas g...
