研究目的
To develop a new quantum dot plate strategy without the use of any expensive barrier film, ensuring quantum dots are homogeneously embedded in the polymeric matrix of the middle layer with upper and lower layers acting as protective layers.
研究成果
The non-barrier-film quantum dot plate shows satisfactory stability comparable to high-barrier-material-based quantum dot films under harsh conditions, offering a cost-effective solution for backlight systems with wider color gamut.
研究不足
The sensitivity of quantum dots to external environments like water and oxygen, and the need for precise control over the manufacturing process to ensure uniform distribution and stability of quantum dots.
1：Experimental Design and Method Selection:
A three-layer co-extrusion method was developed to embed quantum dots in the polymeric matrix without using expensive barrier films.
2：Sample Selection and Data Sources:
Quantum dot powder or solution mixed with PMMA particles, toughening agent, and anti-aging additive.
3：List of Experimental Equipment and Materials:
Granulator, extruder, mixer machine, PMMA materials, quantum dots, toughening agent, anti-aging additive.
4：Experimental Procedures and Operational Workflow:
Mixing materials, granulating, extruding, molding into a three-layer structure, and testing under blue-LED irradiation, high temperature, and high humidity.
5：Data Analysis Methods:
Evaluation of brightness, color gamut, color coordinates, color temperature, color rendering, light transmittance, and haze.
