PCAP TOUCHSCREENS WITH VARYING ITO DICING PATTERNS

PCAP TOUCHSCREENS WITH VARYING ITO DICING PATTERNS

Embodiments include a method and system for projected capacitive (PCAP) touchscreen construction with laser ablation. In glass/film/film (GFF) PCAP touchscreens, the films are coated with indium-tin-oxide (ITO), patterned by printing silver ink, and by ablating both the ITO and silver with a laser....

description Embodiments include a method and system for projected capacitive (PCAP) touchscreen construction with laser ablation. In glass/film/film (GFF) PCAP touchscreens, the films are coated with indium-tin-oxide (ITO), patterned by printing silver ink, and by ablating both the ITO and silver with a laser. A similar process occurs for a glass/glass (2GS) PCAP touchscreen. Embodiments include varying the pattern with which the laser ablates ITO on film within the touch area to improve touchscreen sensitivity. For example, by varying the width of patterns of floating ITO islands such that widths are less than or equal to a plan-view electrode gap between vertical and horizontal electrode pads and larger elsewhere, the touch sensitivity of the PCAP touchscreen may be improved and/or maximum touchscreen size may be increased.
