Quantum dot (QD) color conversion has recently been demonstrated in commercial QD‐OLED displays on the market exhibiting exceptional color gamut coverage, brightness, black levels, and viewing angles. To continue developing QDs for a wide range of future display technologies, two key aspects remain under study. First, how can blue light absorption be maximized for small pixel formats (<10 μm) requiring thin QD color conversion layers and second, as pixel sizes shrink and display brightness increases, how can these materials remain stable under high blue‐light excitation flux (up to 5W/cm 2)? Here we describe experiments addressing these two areas of continued development for heavy‐metal free QDs.
量子点(QD)颜色转换最近已在市场上的商用量子点 - 有机发光二极管(QD - OLED)显示器中得到展示,其具有出色的色域覆盖范围、亮度、黑电平以及视角。为了继续针对广泛的未来显示技术开发量子点,两个关键方面仍在研究之中。首先,对于需要薄量子点颜色转换层的小像素格式(<10μm),如何使蓝光吸收最大化;其次,随着像素尺寸缩小和显示亮度增加,这些材料在高蓝光激发通量(高达5W/cm²)下如何保持稳定?在此,我们描述了针对无重金属量子点这两个持续发展领域的实验。
