We need a much better explanation than just "Ghost Touch". So tell us what specificly happens and under what conditions it happens.
Are you getting resposes like you would expect from a touch pad? Or is it switching on and off with nobody near? Tablets have touch screens and those are quite static sensitive. Is it that sort of symptom?

Tablets have touch screens and due to electrical network touch screen can get touch by itself. When I supply power from UPS there is not any problem but when I connect to electrical network touch screen detect touch without anybody touching.

OK, then the solution is to clean the touch screen completely, get all the fingerprints and smears off and make it look clean. An easy solution for the problem.

I tried it but it didn't solved the problem. The problem cause from electrical network but I dont know how to filter it. I am using adapter which as input 220 Vac and output 12Vdc/1A.
