Title: METHOD FOR PACKAGING LED LAMP BEAD BASED ON QUANTUM DOT FLUORESCENT FILM
Abstract:
Provided is a method for packaging an LED lamp bead (8) based on quantum-dot fluorescent film; The half-wave of the quantum dot material (6, 7) used is narrow, significantly improving the gamut value of the LED lamp bead such that the gamut value of the LED lamp bead reaches NTSC 96% or higher. In comparison with existing packaging methods, packaging with a quantum-dot fluorescent film prevents the quantum dot material from directly contacting a chip (3) and thus prevents the material from being subjected to the high temperature of the surface of the chip, improving the reliability of the lamp bead. Quantum-dot fluorescent film is used to obtain a white LED lamp bead, which can quantitatively control the content of the quantum dots and other light-emitting materials of each lamp bead, reducing the difficulty of packaging and the product defect rate and improving the degree of concentration of the color-producing region, making the invention suitable for large-scale industrial production.
