The product CS12102F170P-C111 uses a ten-point capacitive
touch.
ATTENTION:
Capacitive touch is very sensitive to power noise. Ripple
voltage/current from the power adapter will cause the LCD
ripples and also the capacitive touch to malfunction. If you
use the APK Multi-Touch under Android to test, you can find
the touchpoint float. There are several ways to solve this
problem:
1) Use a high-quality power adapter, or a battery to provide
power like a cell phone or tablet PC.
2) If the power adapter isn’t good enough, make sure the
CS12102F170P-C111 power input connector
Pin 3 is connected to
the Ground
. This method can eliminate the problem totally. You
can test it by touching the GND of CS12102F170P-C111 with one
hand, while the other hand operates on the capacitive touch
screen. In this case, the user’s body acts as the Power System
Ground.
