To help you orient the film, the sheets will have a small notch cut into one of the corners (Except for DBEF-D550;
it has the corner removed). Hold the sheets with the cut notch in the upper right-hand corner to identify the
transmission angle, as illustrated below. When held like this, you will be looking at the upper surface, which must
face the LC glass module, and face away from the backlight.
