3.1 Cleaning the Touch Screen
Caution:
Do not use any cleaners with chemicals that can corrode glass or damage the touch
screen permanently. When cleaning the touch screen, use a soft, lint free cloth to prevent
scratches and contamination. Avoid using sharp/hard objects.
Before integrating the touch screen, make certain it is properly cleaned. It is highly recommended that the
installation of the touch screen is performed in a clean room to prevent any contamination.
1.
Wear powder free gloves before handling the touch screen.
2.
Wear a grounded wrist band to prevent any static damage to electronic components.
3.
Clean both sides of the touch screen with a non-abrasive anti-static solution (lens cleaner).
4.
Clean both sides of the touch screen again with rubbing alcohol.
5.
Repeat steps 3 and 4 as needed until the touch screen is free of all contaminants, such as
fingerprints or dust.
6.
Allow the touch screen to fully dry before integrating.
