New description: [New technical field] This is a kind of capacitive touch panel, especially the area where the lower surface of the protective lens is used as the wiring of the touch panel, (6) to reduce the thickness of the sheet and the optical A capacitive touch panel with adhesive steps attached. [Prior Art] As shown in the sixteenth and seventeenth aspects, the conventional capacitive touch module is a capacitive-type panel (70, 70,) and a protective lens (c〇verL is called Forming and then attaching the two together through the optical adhesive (700). The touch panel (70, 70') can be the single-plate type touch panel (70) of the first figure or the second figure. The double-plate type touch panel (〇) with the upper and lower substrate structures is shown... The anti-good lens (71) is the finger touch end', and the area covered by the touch panel includes the visible area of the touch panel and is pure, even At the display end of consumer electronics (such as mobile phones), the flat surface is designed to be larger than the touch panel (70, 70') itself to cover other non-bits of the electronic product. The rate is low, and when the optical adhesive is not attached (the optical glue, touch panel and protective lens used will have no chance of rework and must be completely scrapped, and the material waste.) Attached to the touch panel or on the Han and 疋 疋 濩 lenses, the last must be both For the key process of the industry, for the industry, this key process has certain difficulty, even the long-term M k, long-term transfer to the subcontractor, which is extremely wasteful of working hours. In addition, when the touch panel is the upper and lower substrate structure When combined with protective lenses, M355426 will cause total thickness and ^ to reverse the term plus 'not in line with today's demand.
