This article describes (Elo Pro-G) PCAP Glass Constructions 2GS, and 3GS

Glass Constructions (Pro-G) 2GS (“Glass-Glass”) design consists of two glass layers – cover glass and sensor glass – both patterned with ITO conductive traces on a single side. The conductive glass sides are then laminated together using OCA. 2GS offers pristine optical clarity, high durability and long term stability over temperature, making it a great choice for demanding commercial and industrial applications up to 24 inches where weight and overall thickness aren’t primary concerns (see figure 2).



3GS is also available and used when there is a need for special cover glass materials such as Gorilla glass or polycarbonate. Glass only constructions are always better from an optical performance standpoint compared to film. 2GS and 3GS offer a naturally robust laminated glass structure. Film based PCAP sensors can also be designed with additional robustness through extra laminated layers or thicker, toughened cover glass. Because of this it’s important to work with an experienced touch technology provider to guide you to the best structure for your particular application.
