Backlit keyboard has one ot two transparent plastic sheets?
I'm installing a backlit panel I bought in eBay behind my non-backlit keyboard for making it illuminated.
The problem is:
The backlit panel has a transparent plastic sheet with white dots in correspondence with the keys ot the keyboard for light diffusion.
My non-backlit keybord also has a transparent plastic sheet just behind the keys, without the white dots for light diffusion but looks almost the same otherwise.
In installing the backlit sheet, should I replace the original transparent sheet with the new one or retain it and install the backlit one just behind it?
I'd think I should replace, but some people seemed to suggest to retain even the former transparent sheet, look the sentence starting with ** in muhibmc reply in this solution:
Questa è una buona domanda?
