Investigation of Brightness, Chromaticity, and Color Gamut by Using Different Wavelengths of Blue Light Excitation on Quantum Dot Color Conversion Layers for the Development of Next-Generation Micro-LED Displays

This research focuses on exploring the conversion of brightness in green and red quantum dot color converters (QDCCs) when exposed to blue light panels with different wavelengths: 437 nm, 450 nm, and 460 nm. The results indicate that as the wavelength of the blue light decreases, the efficiency of QD emission conversion improves, resulting in increased brightness of the converted QDs. However, it is crucial to consider the potential risks associated with short-wavelength blue light exposure to biological tissues, particularly the eyes. As a result, there is a growing emphasis on the development of longer- wavelength blue light for future QD-based micro-LED displays.
