Other Parts Discussed in Thread: TSC2004

Hello,

Customer use TSC2004 and need to add more force to let the touch panel active. Has any suggestion to let TSC2004 more sensitivity to let panel work by slight force? Thank you.

Hi Patrick,

I suggest your customer try some light touch screen panels, which seems to be the easiest solution.

Hi Patrick,

I'm afraid no because the physical features of touch panels are beyond the control of any resistive touch controller. If the two ITO layers of a touch panel are not bent enough by force to have a mutual connection, there is no way that TSC2004 can detect the finger positions.

In addition, as far as I know, choosing a light touch screen will not necessarily increase the system cost.
