Foxconn and Cima NanoTech recently announced a joint venture developing large-format project capacitive (p-cap) touch sensors with silver nanoparticles (NPs) as transparent conductive films (TCF). The new venture aims to use their sensors to replace incumbent infrared (IR) touch sensors in large format applications like interactive white boards, video conference systems, interactive digital signage and casino machines. Compared with IR sensors, p-cap sensors offer faster response time, suppor...
