We have proposed a new method of quantum dots (QD) chip scaled package technology and developed the world-first bin-free QD micro-LED display. Experimental result shows that the wavelength derivations of red and green color of QD CSPs are under 0.6nm, which enables us to use over 95% of a blue wafer. Furthermore, the quantum yield of red ones only drops under 5% after 1000 hours to apply commercial products. From the research work, we expect that the QD μ-CSP will become the core technology to dominate future TV, home theatre, and signage markets.
