  • Patent number: 11441045
    Abstract: An ink composition for inkjet printing organic light-emitting diodes and a method of manufacturing the same are disclosed. The ink composition includes 0.01-40% of bipolar light emission component, 10-99.9% of solvent, 0.01-5% of surface tension modifier, and 0.01-5% of viscosity modifier by weight. The method of manufacturing the ink composition includes steps of: dispersing the bipolar light emission component in the solvent firstly, and then adding the viscosity modifier and the surface tension modifier under stirring, so as to obtain the ink composition. By using the ink composition, specific hole and electron transport layers provided in the organic light-emitting diode manufactured by inkjet printing may be omitted, thereby simplifying the structure of the organic light-emitting diode. Moreover, the ink composition has suitable viscosity, surface tension, and volatility.

  • Publication number: 20220215778
    Abstract: A training method for evaluating the bonding accuracy of orthodontic brackets is provided. The evaluation method includes a training device for racket bonding accuracy evaluation which includes virtual teeth with root-shaped connectors and an evaluation base to fix the virtual teeth. Multiple reference lines are marked on the evaluation base, and their intersection is set as the evaluation point. When the virtual tooth is fixed to the evaluation base, the reference lines and the evaluation points are utilized for rapid evaluation of the bonding accuracy of the bracket. Moreover, thanks to their horizontal arrangement, when there are multiple virtual teeth, the evaluation of bracket bonding would be more intuitive and efficient than using the traditional articulator.
