Yes, it can be done (rebonding the cables that go between the driver
circuit board within an LCD panel to the actual LCD glass), but it the
equipment required is relatively rare and exotic (a laptop with a full
size screen is not the same as a cell phone with a few square inches of
screen). The number of places that do it is small enough, and the cost
is high enough, that as a PRACTICAL matter it is normally not a
realistic option.

It amounts to the same thing, & both are equally unfixable.

They are routinely repaired by places that refurbish large numbers of
cell phones. They replace defective or damaged LCD, and reuse the
cable.
It's a bit different for a full size screen. ;^)


It can be done, with the right equipment.
