Pre-cut tape mask to mount your 5.5" LCD.   Tape mask only, LCD not included. Ready to install. Steps to apply tape to Epax X1 LCD:

1. Download the two cbddlp files which are helpful to display the edge of displayable screen.  You can find the thin frame file here and thick frame file here.
2. Print one of the above cbddlp file to show where the edge of screen is.  Then apply the pre-cut tape to the frame so that the displayed frame is still seen.  On each of the 4 sides there is 1mm room for you.  So you don't necessarily need to apply the tape precisely.
3. If you don't have pre-cut tape, you can use kapton tape for the same purpose.
4. Press down the tape so that it is even and secure.
5. Do an auto home to make sure things are all good.  Then, do an auto home with VAT installed.
