Batteries are replaceable, capacitors are replaceable, memory can be reflashed. Once oled screens degrade, you gotta get a newer production assembly and suddenly that’s hard to find. When you do find it you’re navigating third party parts, it’s not a good quality Samsung model, now not everything fits right, maybe it doesn’t last as long or isn’t as durable.

This is of course all true of any assembly or discrete component but on batteries or diodes for example you have wider tolerance and fit ranges, hell there might be a range of standard types and values with their identifiers written right there on the back of the part.

Oled displays have a lot of the same problems as vfds before them, but with none of the space to stuff a replacement display and microcontroller in there as a replacement.

I truly hope you’re right, that the displays of today will last into the future. It hasn’t been my experience.

I also hope that a new standard is developed that leads to more people breaking their stuff and bringing em to me to fix. It would be cool to not have to learn every new insane tech thing I’ll never personally use.
