In touch panels without optical bonding there is an air gap between the display and the touchscreen. This air gap causes reflections by light refraction at the surfaces of the display and the touchscreen.
To improve the readability of the screen contents in direct sunlight, the optical bonding process provided by SCHURTER is the optimal solution.
Here, the air gap between the décor glass or touchscreen and the display is filled with a highly transparent adhesive.
In addition to substantial improvements in the readability and the contrast and brightness of the colours, the mechanical robustness of the touch panel is increased by Optical Bonding. No condensation moisture can arise and no dust or dirt particles can penetrate. By filling the insulating air gap, heat is dissipated through the front glass to the outside.
