The product CS19108R173P-C111 uses 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 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 to a cell phone or tablet PC.
2) If the user power adapter isn’t good enough, there’s another effective method to solve this problem: Make sure the CS19108R173P-C111 power input connector Pin 3 is really connected to the user “Power System Ground”. This method can eliminate the problem totally. The user can also use another method to solve this problem: touch the GND of CS19108R156P-C111 by 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.
