Why do PCAP touch panels need EMC noise protection?
There are many noise interferences in the environment, which may come from LCD, radio transmission, motor, or power supply...etc. PCAP touch controllers detect changes in capacitance to determine touch positions, so PCAP touch products need to resist EMC interference to avoid false signals. AMT PCAP touch products can pass IEC 61000-4-2 / IEC-61000-4-3 / IEC-61000-4-6 (CS/RS: Level III, 10V), and IEC 60601-1-2 and other specifications.
