At the latest since the widespread introduction of PCAP technology for touchscreens, the visual appearance of a display with a touchscreen has moved into the consciousness of the viewer. Due to the high transparency of the PCAP sensor (in contrast to resistive touchscreens), unwanted reflections of the incident light are noticeable. The optical bonding process minimizes these.
The white paper highlights topics such as components, areas of application, advantages and challenges of optical bonding and explains the individual bonding processes for display and touch in detail.
