Why can’t we fix broken TV screens without fully replacing the panel?
In: 44
I’m sure there are a few broken screens that could be repaired, but those would take specialized equipment and training, and many aren’t repairable at all.
There are layers of glass with invisible electrically conductive traces printed on them. How do you fix such a trace if the glass is broken?
How do you even get access to the trace without causing more damage if it’s glued in the middle of other layers?
There are other problems that can come up, like ICs that drive the rows and columns getting fried, or the flat flex that connects them to the glass getting damaged. These connections are MUCH smaller than a normal circuit board.
