Abstract
A capacitive touch panel structure comprises a display module, a touch detection module and an optical adhesive layer interposed between the display module and the touch detection module. The display module includes a base substrate, a transistor layer and a filter set that are sequentially stacked, namely the filter set is located on the transistor layer. The touch detection module includes a cover board and at least one touch control electrode grown on the surface of the cover board. The touch control electrode is directly formed on the surface of the cover board, hence the thickness of the capacitive touch panel of the invention can be reduced. The display module and touch detection module are made separately and bonded together via the optical adhesive layer, hence fabrication difficulty is lower and production yield is higher. Thus production speed and productivity are increased, thereby reducing production cost.
