Abstract

A micro LED displaying apparatus is provided. When the micro LED displaying apparatus is damaged by external forces, the circuits corresponding to the impact area are damaged and unable to display images normally. However, according to the technologies of the present invention, the remaining area can still display images normally. That is, even if the micro LED displaying apparatus is damaged by external forces, a large area of the micro LED displaying apparatus of the present invention can still display images normally. Consequently, the micro LED displaying apparatus of the present invention is suitable for specified fields with strict verification standards.
