The Impact of Luminous Properties of Red, Green, and Blue Mini-LEDs on the Color Gamut
Weijie Guo,Nan Chen,Hao Lu,Changwen Su,Yue Lin,Chen Guolong,Yijun Lu,Lili Zheng,Zhangbao Peng,Hao-Chung Kuo,Chih Hao Lin,Tingzhu Wu,Zhong Chen +12 more
TL;DR: In this paper, the influence of temperature and driving current on the chromaticity coordinates of mini-LEDs is determined and a drive-current algorithm is proposed to maximize the color gamut of trichromatic mixed light at different temperatures.
Journal ArticleDOI
Effect of Carrier Localization and Shockley-Read-Hall Recombination on the Spatial Distribution of Electroluminescence in InGaN LEDs
TL;DR: In this article, a phenomenological model is proposed to account for the competitive mechanism between the carrier localization and the SRH recombination in light-emitting diodes (LEDs).
Journal ArticleDOI
Interplay of carriers and deep-level recombination centers of 275-nm light-emitting diodes — Analysis on the parasitic peaks over wide ranges of temperature and injection density
Tingzhu Wu,Yue Lin,Zhangbao Peng,Huashan Chen,Zhibin Shangguan,Liu Meng,Sung Wen Huang Chen,Chih Hao Lin,Hao-Chung Kuo,Zhong Chen +9 more
TL;DR: A thorough investigation on the interplay among carriers and various types of defects should be conducted on the basis of the measurement taken under a wide temperature range, as well as under a proper forward voltage to let the quasi-Fermi level shift across deep defect levels, the band-edge, and to over-band.
Journal ArticleDOI
Origins of Inhomogeneous Light Emission From GaN-Based Flip-Chip Green Micro-LEDs
Weijie Guo,Changwen Su,Hao Lu,Zhangbao Peng,Zhijie Ke,Yijun Lu,Tingzhu Wu,Yue Lin,Zhong Chen +8 more
TL;DR: In this paper, the spatially resolved electroluminescence emitted through the sapphire substrate of GaN-based flip-chip green micro-scale light-emitting diodes with $20\times 20,\,\mu \text{m}^{\text {2}}$ mesas has been collected via microscopic hyperspectral imaging.
Journal ArticleDOI
Temperature-Dependent Carrier Recombination and Efficiency Droop of AlGaN Deep Ultraviolet Light-Emitting Diodes
TL;DR: In this article, the authors investigated temperature-dependent carrier transfer and efficiency droop on AlGaN-based deep ultraviolet light-emitting diodes and identified the existence of Auger recombination and carrier leakage by the m-power method.
