  • Patent number: 11971166
    Abstract: 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.

  • Patent number: 10196359
    Abstract: 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.

  • Patent number: 10153407
    Abstract: 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.

  • Patent number: 8013347
    Abstract: A remote-controllable lighting device comprising a first substrate and an adjacent second substrate maintained in a spaced apart relationship to allow airflow therebetween and at least partly overlapping each other, at least the second substrates carrying thereon at least one emission sources, the first substrate being located towards a proximal end of the device and the second substrate being located towards a distal end of the device; said first substrate being arranged so as to allow light generated by the at least one located second light emission source to pass thereby in a direction defining a primary light emission direction and said first light emission source located so as to emit light in said primary light emission direction; said first and second substrate being in thermal communication so as to allow heat generated by the at least one light emission sources to flow between the substrates so as to provide thermal distribution between the substrates, the first and second substrate being formed of a
