there had to ladhésif for the top and bottom of the screen the first time ... it does not perfectly corresponded ladhésif but was full (it is best to stick ladhésif the entire LCD panel to avoid Dust ... (mini paint roller foam))
It is no longer possible to seal the screen to dust in these conditions; we must add ladhésif at his expense.
(Give at least enough to make the full rotation, or 2 strips to go around the LCD.)
