May depend upon whether your touch panel is resistive, capacitive or multi-touch capacitive. TI has compact, multi-channel signal "isolators" which we've used to gain some ESD protection and reduce emissions. Suspect that a search under ESD on the TI site will produce a list of suitable, transient absorbing components.
Touch panel vendor or display provider should be mined for their recommendations as well... It's good that you're thinking about ESD early (rather than later) in your design & build process.
Thanks for the answer I forgot the main information: is a resistive touch for a small display about 4 " I am worried because the touch panel is obviously on "top" on my box and I think the real problem is not make it work but "protect it from trouble" I searched on the TI website and I found a lot of information about ESD protection I hope to find the right solution ... thanks
Hope you have found the righ solution for your touch ESD protection.
Please feel free to share if you have any questions on your ESD protection solution.
