The Full-color Micro-LED Display with Quantum Dots Inkjet Printing

A color conversion film, including red and green quantum dots, is fabricated using inkjet printing. To ensure the efficiency of the color conversion, a color filter is utilized to remove extra blue light. By selecting the appropriate central wavelength for the filter, the color conversion film can convert blue light to red and green light without extra blue light. The color conversion film is stimulated by blue micro-LED, and the resulting color gamut can achieve 84.5% BT.2020. These results demonstrate that combining a quantum dots film with a color filter can result in full-color micro-LED displays.
