A method for forming a touch film stack roll is provided. First, a stack roll is provided. The stack roll comprises a bottom substrate roll, a patterned bottom conductive layer, a bottom strip layer and a top conductive roll. The bottom strip layer covers the bottom conductive terminals of the patterned bottom conductive layer. Then, the top conductive roll is patterned to form a patterned top conductive layer with top conductive terminals. Next, a top strip layer is formed on the top conductive terminals. Later, a top OCA roll is attached to the stack roll to cover the top strip layer to obtain the touch film stack roll.

Stack film roll and stack film sheet obtained therefrom

A touch panel includes a substrate, a first patterned transparent conductive layer, at least one insulating block and a second patterned transparent conductive layer. The first patterned transparent conductive layer is disposed on a substrate and includes at least one first connection electrode. The insulating block is disposed on the substrate and at least partially covers the first connection electrode. The second patterned transparent conductive layer is disposed on the insulating block and the first patterned transparent conductive layer. The second patterned transparent conductive layer includes at least one second connection electrode disposed on the insulating block. A thickness of the second patterned transparent conductive layer is smaller than a thickness of the first patterned transparent conductive layer.
