研究目的
To propose a full-color Micro-LED display using high brightness blue Micro-LED array with red and green photoluminescence quantum dots as color conversion materials.
研究成果
The study demonstrates the feasibility of using blue-light Micro-LEDs to excite red and green quantum dots for full-color displays. The use of a DBR film significantly improves color conversion by reducing blue light emission. Future research will focus on patterned quantum dot films and better DBR designs to further enhance display quality.
研究不足
The thin quantum dot film's low absorption rate of blue light and the challenge of completely absorbing blue light even with a thicker film. The need for more effective methods to reduce blue light emission in full-color displays.
1：Experimental Design and Method Selection:
The study uses a Mini-LED array to excite quantum dots as a preliminary step before using a Micro-LED array, due to the larger display area and more obvious display effect provided by Mini-LEDs.
2：Sample Selection and Data Sources:
A Mini-LED array with a peak wavelength of 455nm and a resolution of 32 × 32 was used. Quantum dots with red and green colors were prepared.
3：List of Experimental Equipment and Materials:
Mini-LED array, quantum dot solutions, glass sheets, spin coater, DBR film.
4：Experimental Procedures and Operational Workflow:
Quantum dot solutions were dropped on glass sheets, spin-coated, and placed above the Mini-LED array to observe color conversion effects. A DBR film was used to decrease blue light emission.
5：Data Analysis Methods:
Observation of color conversion effects and analysis of the effectiveness of DBR film in reducing blue light emission.
