METHOD FOR PACKAGING COATED QUANTUM-DOT LED LAMP BEAD

摘要

Provided is a method for packaging a coated quantum-dot LED lamp bead. The half-wave of the quantum dot material used is narrow, significantly improving the gamut value of the LED lamp bead such that the gamut value of the obtained LED lamp bead reaches NTSC 93% or higher; an epoxy resin is used for pre-coating the quantum dot material, blocking external moisture and oxygen from corroding the quantum dot material and also improving the reliability of the lamp bead; a quantum-dot fluorescent powder is used to obtain a white LED lamp bead; the quantum-dot fluorescent powder has a high excitation efficiency and the density of the fluorescent powder during the packaging process is low, reducing the difficulty of packaging and the product defect rate and making the invention suitable for large-scale industrial production.
