A direct patterning method of touch panel is provided. A substrate having a display region and a peripheral region is provided. A periphery circuit having a bonding pad is disposed on the periphery region. A metal nanowire layer made of metal nanowires are disposed on the display region and the peripheral region. A photosensitive pre-cured layer is disposed on the metal nanowire layer. A photolithography process is performed, which includes exposing the pre-cured layer to define a removal area and a reserved area, and removing the pre-cured layer and the metal nanowire layer on the removal area using a developer solution to form a touch-sensing electrode disposed on the display region and to expose the bonding pad disposed on the periphery region. The touch sensing electrode made of the pre-cured layer and the metal nanowire layer is electrically connected to the periphery circuit.

Direct patterning method for a touch panel and touch panel thereof

A manufacturing method for a touch panel includes defining a removing area of a photo-sensitive conductive layer and a photo-sensitive layer by an exposure process. On a display area, the photo-sensitive layer and a metal nanowire layer in the removing area are removed by a developer solution so as to form a touch sensing electrode on the display area. On a peripheral area, the photo-sensitive conductive layer, the photo-sensitive layer, and the metal nanowire layer in the removing area are removed by the developer solution so as to form a peripheral trace on the peripheral area. The touch sensing electrode and the peripheral trace are electrically connected with each other.

Touch panel and manufacturing method therefor

A touch panel includes a substrate, first and second touch sensing electrodes, and first and second traces. The substrate includes a display area and a peripheral area. The first and second touch sensing electrodes are formed on the display area, and the first and second traces are formed on the peripheral area. The first touch sensing electrode is formed by a first portion of a metal nanowire layer, which is patterned. The peripheral trace includes a conductive layer and a second portion of the metal nanowire layer, both of which are patterned in a co-etch step. The conductive layer and the second portion of the metal nanowire layer have a coplanar etched surface. The second touch sensing electrode is formed on an insulating layer and connects with the second trace.
