Resistive touch panel - image distortion

[aleksey_au]

I have bought Fujitsu Feather Touch resistive NC01111-T222 touch panel
it works very well but I see some image distortion:
the screen is like covered by millions of very small dots that shimmer by different colors if viewer moves.

I attached the photo, on the left lighter side the grid is actually the borders between physical pixels of LCD,
it is visible that the borders and pixels are distorted.

Is it the effect of spacer dots or what?

Is it possible to find the resistive touch panel without image distortion?

Where is the good opto-electronics forum about touch panels?
