Purple glow/reflection
Thre is purple halo effect around the edges of iphone 12 and iphone 12 Pro devices visible on tight angle. If I turn on the device, on white/color screen, they do not appear but on black screen they still appear on turned on device.
I detached the screen thinking it might be compression but still same issue.
Is it expected thin film interference or light is inappropriately refracting due to front glass quality, deformed OCA/polarizer? Could the lamination/pressing tool have applied excessive pressure to the middle of the screen or did the OCA glue spread unevenly during the UV curing? Do you think it can go away if the front glass gets replaced?
The last picture, under UV light, shows a rounded recatangular shape visible in the middle of the both screens.
