  • Publication number: 20240012499
    Abstract: A touch sensor includes a substrate, sensing channels, and a protective layer. The sensing channels are disposed at intervals on a surface of the substrate, and any one of the sensing channels includes an electrode portion and a silver trace portion electrically connected to the electrode portion. The protective layer is disposed on the substrate and covers and encapsulates the sensing channels. After the touch sensor is subjected to a salt spray test with sodium chloride solution of a mass percentage concentration of 5% at a rate of 1 mL/H to 2 mL/H under an ambient temperature of 35° C. for 48 hours, a resistance change rate of any one of the sensing channels is less than or equal to 10%, and a resistance distribution difference between the sensing channels is less than or equal to 10%.

  • Patent number: 11106321
    Abstract: 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.

  • Patent number: 11106130
    Abstract: 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.

  • Patent number: 11061501
    Abstract: 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.
