The display on my laser cutter has been getting progressively harder to read, this initially looked like someone had left the screen protector on and it was starting to peel off with time. I decided to pull it apart and remove the protector but it was a bit worse than that. The poor extraction on the machine basically leaves dust all over everything, the exposed electronics are no exception. The dust was creeping in between the display and the panel. So I removed the offending screen protector, cleaned up the panel and when I put it all back together I wrapped the whole thing in cling film and then cut the front film off. I'm hoping this will prevent any more dust ingress between the display and the panel.
