DEUTA uses optical bonding as standard for new terminal series. The additional finishing process optimises image quality and reading angle by increasing contrast sharpness and minimising reflections.
In optically bonded DEUTA terminals, the air
gap between the cover glass with touch sensor and the
display is closed by a highly transparent bonding material. Without optical bonding, the air gap between the touch unit and display generates additional light refraction. Optical bonding eliminates completely this light refraction.
With optical bonding, scratches become invisible, the image display improves and optical problems or malfunctions caused by condensation do not occur.
The full-surface bonding creates a stable bond with improved touch performance.
Still easily readable even from an inconvenient viewing angle: this also makes the driver's job significantly less tiring.
In terms of design, the bonded stability allows more intricate terminal developments with thinner displays which bring a more modern look to the driver's cab.
