Abstract

The invention provides a touch panel and a manufacturing method thereof, wherein a conductive layer is arranged on a substrate and an OCA optical adhesive layer is arranged on the conductive layer. The conductive layer is made of a silver-containing material and comprises a virtual wiring region and a functional region, and a specific pattern is arranged at the junction of the virtual wiring region and the functional region to electrically insulate the virtual wiring region from the functional region. The specific pattern is arranged at the junction of the virtual wiring area and the functional area, the distance between the virtual wiring area and the functional area is correspondingly enlarge, and the silver migration risk of the nano silver wire layer is effectively reduced. Furthermore, through adoption of the filling etching lines in the inner part of the functional area, the visual difference between the functional area and the virtual wiring area is reduced, and the visual effect of the etching marks is further reduced.

Description

technical field

[0001] The invention relates to the field of touch technology, in particular to a touch panel and a manufacturing method thereof. Background technique

[0002] The touch panel (Touch Panel) has gained more and more applications in display technology fields such as tourist guide systems, automatic teller machines, portable electronic products, and industrial control systems because of its convenient use. The touch panels with the highest usage rate are mainly resistive touch panels and capacitive touch panels, but for the sake of controllability, ease of use and surface appearance, most users choose capacitive touch panels as their best choice. Best preferred equipment.

[0003] In a capacitive touch panel of a traditional smart phone, the material of the touch electrode is usually indium tin oxide (abbreviated as ITO). ITO has the characteristics of high light transmission and good electrical conductivity, but the surface resistance of ITO is too large and ...

Embodiment Construction

[0031] Such as figure 2 As shown, it is a top view of the conductive layer in the prior art, such as figure 2 As shown, the conductive layer includes a dummy wiring area (Dummy Pattern) 11 and a functional area 12 . Wherein the dummy wiring area 11 is distributed in an area outside the functional area 12 and is not electrically connected to the functional area 12 .

[0032] Please continue to refer figure 2 As shown, the dummy wiring area 11 is provided with a separation etching line 111 , and the separation etching line divides the dummy wiring area 11 into a plurality of independent floating blocks 112 . The dummy wiring area 11 and the functional area 12 are isolated by the separation etching line 111 ′. Under the conditions of high humidity environment and external electric field, water molecules penetrate into the surface of silver-containing conductor and electrolyze hydrogen ions (H +) and hydroxide ions (OH - ), the silver in the silver-containing conductor wil...
