Capacitive Touch
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
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 CS10768F097P-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.
