Fabrication of Flexible White Light-Emitting Diodes from Photoluminescent Polymer Materials with Excellent Color Quality
This
study developed flexible light-emitting diodes (LEDs) with
warm white and neutral white light. A simple ultraviolet flip-chip
sticking process was adopted for the pumping source and combined with
polymer and quantum dot (QD) films technology to yield white light.
The polymer-blended flexible LEDs exhibited higher luminous efficiency
than the QD-blended flexible LEDs. Moreover, the polymer-blended LEDs
achieved excellent color-rendering index (CRI) values (Ra = 96 and
R9 = 96), with high reliability, demonstrating high suitability for
special applications like accent, down, or retrofit lights in the
future. In places such as a museum, kitchen, or surgery room, its
high R9 and high CRI characteristics can provide high-quality services
