1Hybrid-type white LEDs based on inorganic halide perovskite QDs: candidates for wide color gamut display backlights显示文摘We demonstrate inorganic halide perovskite quantum-dots-based white light-emitting diodes via three different geometries, including liquid, solid, and hybrid types. Problems of fast anion exchange and aggregation in the cases of liquidand solid-type devices are discussed in detail and push us to move towards the fabrication of a hybrid-type device structure. The experiment results illustrate that a hybrid-type device has the highest luminance efficiency(51 lm/W) and a wide color gamut(122% of NTSC and 91% of Rec. 2020). Therefore, we conclude that a hybrid-type device can provide an outstanding color gamut for high color gamut display applications.Chih-Hao Lin Akta Verma Chieh-Yu Kang Yung-Min Pai Tzu-Yu Chen Jin-Jia Yang Chin-Wei Sher Ya-Zhu Yang Po-Tsung Lee Chien-Chung Lin Yu-Chuan Wu S.
