Has anyone tried attaching this to the inside of the speaker panel rather than the display itself? Because this is polarizing film I understand you can't reverse its direction. Can anyone tell me if this is possible or seems to be possible? I am wanting to use this with a PIN2DMD LED display which uses two halves for the actual display. I don't want to attach the film directly to it because I want to adjust the halves and line them up in the future if I need to, plus replacing only one of two modules in the future if one goes out.
