GOB LED displays can be repaired even when faulty. Minor marks may remain due to the adhesive coating. However, since the replacement glue matches the original, the traces are barely visible and will not affect normal display performance.

To clarify, LED displays are electronic products. As long as they function properly and deliver clear images, while featuring enhanced sturdiness and decent anti-collision performance, they can be regarded as high-quality products.
In comparison, TVs cannot be made in such large sizes. Their glass panels are irreparable once damaged by impact. Therefore, accepting minor imperfections is often the best practical solution for now. After all, technology keeps evolving, and no one can predict future developments.
