Micro-LED displays are emissive flat-panel प्रौद्योगिकियों built from inorganic gallium nitride एलईडी chips with individual pixel dimensions typically below 100 micrometres, delivering luminance levels, contrast ratios, and operational lifespans that neither OLED nor LCD architectures can match at equivalent pixel densities. The fundamental उत्पादन problem — transferring billions of defect-free microscale die from epitaxial wafers onto active-matrix backplanes at production-viable speed and yield — remains the central bottleneck separating laboratory demonstrations from mass-market panels, driving intense पेटेंट मास ट्रांसफर विधियों, लेजर लिफ्ट-ऑफ, स्व-असेंबली और अतिरेक-आधारित मरम्मत रणनीतियों के आसपास की गतिविधि।
