PIA Automation has already developed and installed several optical bonding systems for customers from various industries and regions. Especially for premium household appliances, the displays must meet the highest requirements - with high-contrast information in high color brilliance and precise control with the finger.

It has a significant influence on the operation, the display of the colors, legibility, and overall quality of the display. With Liquid Optical Clear Adhesive Bonding (LOCA bonding), the supreme discipline of optical bonding, a bonding filler is applied between the glass bezel and the touch glass behind it, which is distributed evenly and bubble-free between both components. Displays produced in this way are clear and color-intensive, less sensitive to reflections from external light sources, and pollution and more robust – as glass cover, dispensing materials and touch sensor, form a stable composite.
