Abstract
A touch panel has a substrate having a display region and a peripheral region, a touch sensing electrode disposed in the display region of the substrate, and a peripheral circuit disposed in the peripheral region of the substrate. The touch sensing electrode is electrically connected to the peripheral circuit, and the touch sensing electrode layer includes a first portion of a patterned metal nanowire layer. The peripheral circuit includes a patterned conductive layer and a second portion of the metal nanowire layer. At least a non-conductive material of the conductive layer is between the peripheral circuit and a second peripheral circuit.
Claims19
A touch panel, comprising:
- a substrate having a display region and a peripheral region;
- a touch sensing electrode disposed in the display region of the substrate;
- and
- a peripheral circuit disposed in the peripheral region of the substrate, the touch sensing electrode being electrically connected to the peripheral circuit,
- wherein, the touch sensing electrode comprises a first portion of a metal nanowire layer that is patterned, the peripheral circuit comprises a conductive layer and a second portion of the metal nanowire layer that are patterned, the conductive layer comprises conductive filler particles and a non-conductive material, and the non-conductive material in the conductive layer is between the peripheral circuit and a second peripheral circuit.
A method of manufacturing a touch panel, comprising:
- providing a substrate having a display region and a peripheral region;
- disposing a metal nanowire layer comprising metal nanowires and disposing a conductive layer on the substrate, a first portion of the metal nanowire layer being disposed in the display region, a second portion of the metal nanowire layer being disposed in the peripheral region, and the conductive layer being disposed in the peripheral region and comprising conductive filler particles and a non-conductive material;
- and
- performing a patterning step, comprising patterning the first portion of the metal nanowire layer disposed in the display region to form a touch sensing electrode and concurrently patterning the conductive layer and the second portion of the metal nanowire layer disposed in the peripheral region to form a peripheral circuit, wherein at least the non-conductive material of the conductive layer that is not removed during the patterning step is between the peripheral circuit and a second peripheral circuit.
