Touch panel and device thereof

Abstract

The present disclosure relates to the field of touch technology, and provides a touch display module including a substrate, a transparent conductive layer, a moisture barrier layer, and a display element. The transparent conductive layer is disposed on the substrate. The moisture barrier layer extends laterally on the transparent conductive layer and covers the transparent conductive layer, and the moisture barrier layer includes inorganic materials. The display element is disposed on the moisture barrier layer. The touch display module of the present disclosure can avoid or slow down the water vapor / humidity intrusion from the environment, thereby meeting the specification requirements for improving product reliability test.

Description

BACKGROUNDField of Disclosure[0001]The present disclosure relates to the field of touch technology, and in particular to a touch panel with high water resistance and a device thereof.Description of Related Art[0002]In recent years, with the continuous development of touch technology, transparent conductors can simultaneously allow light to pass through and provide appropriate conductivity. Therefore, transparent conductors are often used in many display or touch-related devices. Generally speaking, transparent conductors can be various metal oxides, such as indium tin oxide (ITO), indium zinc oxide (IZO), cadmium tin oxide (CTO), or aluminum-doped zinc oxide (AZO). However, films made of these metal oxides cannot meet the flexibility requirements of display devices. Therefore, a variety of flexible transparent conductors have been developed today, such as those made of metal nanowires and other materials.[0003]However, the displays or touch devices made of metal nanowires still have...

AI Technical Summary

Benefits of technology

The present patent provides a solution to prevent the electromigration of metal nanowires caused by water vapor in a touch display module. This is achieved by adding a moisture barrier layer and / or an adhesive layer of suitable material to the module. The moisture barrier layer and / or adhesive layer can reduce water vapor intrusion and slow down the time of electromigration of metal nanowires, thereby improving the product's reliability test. The moisture barrier layer and / or adhesive layer has higher resistance to moisture / water vapor.

Problems solved by technology

However, films made of these metal oxides cannot meet the flexibility requirements of display devices.

However, the displays or touch devices made of metal nanowires still have many problems that need to be solved.

However, the polymer film is often made of organic materials, and the polymer film often extends to a peripheral region of the device, resulting in leakage.

Therefore, the water vapor / humidity in the environment easily invades from the polymer film layer, resulting in insufficient reliability of metal nanowires.
