Transparent conductive films are an essential component of a resistive touchscreen. They not only determine the electrical performance of these devices, but also have direct impact on optical performance and durability of these components.
Low resistivity films are used to provide shield layers against EMI, RFI or ESD and they also impact the touchscreen’s optics and mechanical performance.
Non-conductive films such as buffer layers and polarizers also play a crucial role in a well designed touchscreen. Buffer layers add durability and enhance optics while polarizers and other optical films improve viewability and privacy.
