Dual-substrate capacitive touch panel
First Claim
1. A capacitive touch panel, comprising:
- a lower panel comprising;
a first glass substrate having a first circuit surface;
a lower touch sensitive layer mounted on the first circuit surface of the first glass substrate; and
a lower conductor layer mounted on the first circuit surface of the first glass substrate and electrically connecting the lower touch sensitive layer;
an upper panel comprising;
a second glass substrate having a second circuit surface;
an upper touch sensitive layer mounted on the second circuit surface of the second glass substrate;
an upper insulation ink layer mounted on an edge portion of the upper touch sensitive layer, and having a plurality of upper through slots formed through the upper insulation ink layer and each filled in with an upper conductive layer having a color identical to that of the upper insulation ink layer; and
an upper conductor layer mounted on the upper insulation ink layer and electronically connecting the upper touch sensitive layer via the upper conductive layer; and
a transparent insulation adhesive layer interposed between the upper panel and the lower panel.

Abstract
A capacitive touch panel sequentially has a first glass substrate, a lower touch sensitive layer, a lower insulation ink layer, a lower conductor layer, a lower insulation layer, a lower conductive adhesive layer, a flexible circuit board, a transparent insulation adhesive layer, an upper insulation layer, an upper conductive adhesive layer, an upper conductor layer, an upper insulation ink layer, an upper touch sensitive layer and a second glass substrate. The aforementioned structure allows fabrication of the capacitive touch panel to be separated into a lower panel fabrication process and an upper panel fabrication process. The two independent fabrication processes prevent the capacitive touch panel from being damaged in one of the processes when the process is completed so as to increase the yield in production and further facilitate producing large-size touch panel.
