Testing Resistive Touch Panel
« on: December 22, 2016, 11:14:55 AM »
I have a NHD-2.4-240320CF-CSXN#-FT display with a resistive touch screen. I want to do a passive test of the touch screen by checking the resistance between YU,YL and XL,XR.

I connected my Ohm meter between YU and YL which shows no conductivity. Next I touch the screen and still no conductivity.

Is this the way to test a resistive touch panel?

Btw. I do have AR1021-I/SO and a TSC2003IPWR to test with as a next step.

If not doing a simple test with am ohm meter, is there another simple test I can do before I hook up an IC to its touch screen wires?

Thanks!
