Capacitive Touch
The product CS19108R156P-C111 uses ten-point capacitive touch.
BE ATTENTION:
Capacitive touch is very sensitive to power noise. Ripple voltage/current from the power
adapter will cause the LCD ripples, and will also cause the capacitive touch malfunction:
If you use the APK Multi-Touch under Android to test, you can find the touch point float.
There are several ways to solve this problem:
1) Use a high quality power adapter. Or use battery to provide the power like cell
phone or tablet PC.
2) If user power adapter can
’t be good enough, there’s another effective method to
solve this problem: Make sure the CS19108R156P-C111 power input connector
Pin 3
really connect to user
“Power System Ground”
. This method can eliminate the
problem totally. User can also use another method to test this problem: touch the GND
of CS19108R156P-C111 by one hand, the other hand operates on the capacitive touch
screen. In this case, user
’s body acts as the Power System Ground.
