Dear all,

Anyone show me how to control touch panel by FPGA or uP ???
Or where I can get detail info. about that ??
Thank you for reply:)

you could look at TI's ADS7843 to see what's inside the touch screen IC. That's analog stuff, not suitable for FPGA.
 

The main methods for touch screens are resistive and capacitive. They are *definately* analogue systems.

If you want info on capacitive touchscreen systems, try here:

They have some good technical docs on the theory.

or here for ELO systems:
