Abstract
Embodiments enhance graphic capabilities in projected-capacitive (PCAP) touch sensitive systems, and more specifically to a border component of a PCAP touchscreen. Embodiments include a method and an apparatus for a PCAP touchscreen layered structure. Some embodiments include screen printing a border component on a cover sheet, curing the border component, ablating a pattern on the border component, and screen printing one colored ink onto the pattern on the border component. In some embodiments the border layer is black, and the colored ink is coupled to a cover sheet. The pattern causes the colored ink to appear as a continuous gradient of the colored ink. In some embodiments the border component includes two or more border-layer components. At least one of the border-layer components may include an ablated pattern. Each ablated pattern may be coupled to a different colored ink.
