Abstract

Abstract : In displays that use QD as color conversion materials, the QD layer must re‐absorb the blue light that passes through it to achieve high‐luminance red and green pixels. In this study, a low refractive index layer was introduced between the color filter and the QDs layer to reuse the light that passes through the QDs layer. This result shows that there is an 8% increase in luminescence compared to that in Ref.
