Abstract
Some embodiments include fabricating a narrow border of a projected capacitive (PCAP) touchscreen. Some embodiments include a vertical electrode on a cover glass coupled to a first set of traces within the narrow border, and printing a first insulating black mask (BM) layer on the cover glass, that includes a first opening above an electrode terminus of the vertical electrode. Some embodiments further include printing a portion of a conductive black via (BV) in the first opening, coupling the conductive BV to the electrode terminus and a first silver trace of the first set of silver traces. Some embodiments include combining the cover glass with a sensor glass, where the first set of silver traces substantially overlaps a second set of silver traces of the sensor glass within the narrow border, where the overlapped sets of silver traces are separated by a shield layer.
