Hello
There are no only processors in life !
What is the function of the plastic film on resistive touch screens?
I took it for transport/handling protection and I took it off before settings !!!
After calibration the touch panel works but with a variable horizontal offset (zero at the top and maximum at the bottom).
Is this due to my manipulation or to the old image (release_3) ?
The display problem is solved, but the question of the plastic sheet remains :
what is its function ?
The top plastic sheet is pretty standard for all displays. It is placed for protection - from scratches, from fingerprints, from dust, from dirt. Remove it if you want and when you are comfortable.
