The backlight of COG products falls off and require re-gluing, which wastes time, reduces efficiency, and affects product aesthetics. It is indeed necessary to prevent this problem from the design stage.

1) If space available, it’s suggested to add hooks to the light guide plate.
2) Choose materials with high viscosity.
