You may remember that we were visitors to the C-TOUCH Touchscreen Expo 2014 in Shanghai in May. We not only visited exhibitors with products and services related to touchscreens, but also took a look at individual modules and components, as well as machines for the production of touchscreens.

At the Phoseon Technology booth, for example, we learned about LED UV curing applications. These are also used, among other things, for curing adhesives in touchscreen displays.

Phoseon Technology is the market leader in this field and you could get an overview of the latest product range, which is offered in different sizes, at the Expo. With the help of the specially developed SLM technology (semiconductor light matrix), the company achieved a breakthrough in the field of high-performance irradiation.

According to the manufacturer, their products are ideally suited for the touchscreen area because less heat is used. The heat generated by UV LED irradiation corresponds to only 1/10 of the heat generated by conventional UV irradiation. The curing process is not carried out by solvent evaporation, but polymerization of UV-sensitive material.
