Abstract
A capacitive touchscreen panel and a method for etching an indium tin oxide film on a gap portion of a capacitive touchscreen panel, the method for etching comprises using a laser etching line to cut ITO on the gap portion into a plurality of ITO segments, the ITO segments are independent of each other and are not connected to each other. The method for etching an indium tin oxide film on a capacitive touchscreen panel and a gap portion thereof of the present invention has high production efficiency, and the touchscreen product has a good display effect after etching.
