PCAP touch displays feature customised protective glass

"More and more manufacturers provide TFT displays with an integrated PCAP touchscreen as a standard, which is handy for a quick and easy integration," explains Matthias Keller, Head of Sales & Marketing Components at Distec. "But if the application requires an additional custom front glass, the assembly with a conventional optical bonding process is very difficult or even impossible due to the missing frame. Here, our VacuBond(r) Optical Bonding offers the right solution."

A front glass with an individual design, for example, with a logo print or colored frame turns the finished product into an eye-catcher. It also protects the touch screen from external influences such as weather or vandalism. VacuBond(r) allows for bonding a customised protective glass on the PCAP surface because of a dam as for the wet bonding process is superfluous. During the VacuBond process, the high-quality Opto alpha-Gel combines the touch display securely with the protective glass - without any heat or other potentially harmful influences on the unit.

In addition, optical bonding increases the resilience to mechanical stresses such as vibration and shock; the silicone gel works against vibrational resonances and dissipates the energy of impacts. Closing the air gap between touch display and protective glass reduces the light refraction. Thus, the readability of the display is significantly improved without increasing the brightness and therefore the power consumption. In addition, neither dust nor moisture can ingress, settle and thus impair the optical impression.
