Patent number: 11971166Abstract: Provided are a quantum dot display panel, a preparation method, and a display device. The quantum dot display panel includes a backlight module, a quantum dot color filter structure, a first reflecting layer and a second reflecting layer. The quantum dot color filter structure is positioned on a light exit side of the backlight module. The quantum dot color filter structure includes at least a red quantum dot color filter unit, a green quantum dot color filter unit and a composite quantum dot color filter unit. The first reflecting layer is arranged on a side of the quantum dot color filter structure facing away from the backlight module. The first reflecting layer covers the red quantum dot color filter unit and the green quantum dot color filter unit. The second reflecting layer is arranged on a side of the backlight module facing away from the quantum dot color filter structure.Type: GrantFiled: March 23, 2021Date of Patent: April 30, 2024Assignee: SHENZHEN PLANCK INNOVATION TECHNOLOGY CO., LTDInventors: Danpeng Gao, Zhikuan Zhang, Limin Yang, Xiaowei Sun

Patent number: 10196359Abstract: 2-alkoxy benzene formyl arylamine compounds and their pharmaceutical salts are disclosed. The compounds can act as sphingomyelin synthase (SMS) inhibitors to treat diseases caused by abnormal increasing of sphingomyelin (SM). The pharmaceutically acceptable salts and pharmaceutical compositions of the compounds are used as active ingredients in drugs which can prevent and cure diseases caused by SM level abnormal increase. These diseases include atherosclerosis, fatty liver, obesity, type diabetes, and other metabolic syndromes.Type: GrantFiled: July 24, 2015Date of Patent: February 5, 2019Assignee: FUDAN UNIVERSITYInventors: Deyong Ye, Yali Li, Lu Zhou, Penghui Wang, Yong Chu, Haojun Gong, Qi Huang, Yan Chen, Zhikuan Zhang

Patent number: 10153407Abstract: A packaging method of high color gamut white light quantum dot (QD) light emitting diodes (LEDs). The method includes: a. add an organic solvent to red light QD phosphor powder and blue light QD phosphor powder, respectively; b. perform ultrasonic processing for the solutions; c. prepare a mixed QD solution; d. add mixed packaging glue to the mixed QD solution; e. remove the organic solvent; f. add green light rare earth phosphor powder; g. drip the mixed phosphor glue into an LED stent fixed with ultraviolet chips, and bake and solidify the LED stent to obtain LED beads. The method produces high gamut white light LEDs and greatly improves the color gamut value of LED backlight beads, which reaches above NTSC 92%. With an organic solvent as a connecting bridge, QDs and the packaging glue are mixed uniformly, QD phosphor powder failure resulted from agglomeration is avoided, and quality of high color gamut white light LED beads is significantly improved.Type: GrantFiled: December 20, 2016Date of Patent: December 11, 2018Assignee: Shenzhen Jufei Optoelectronics Co., Ltd.Inventors: Zhikuan Zhang, Qibin Xing, Danpeng Gao, Ni Zhang
