  • Patent number: 11915663
    Abstract: A common voltage driving circuit, a display device, and an electronic device are provided. The common voltage driving circuit includes multiple scan lines and multiple common-voltage signal lines, and further includes multiple common electrode units arranged in an array. The multiple scan lines extend in a first direction and are arranged at intervals in sequence in a second direction perpendicular to the first direction. The multiple common-voltage signal lines extend in the second direction and are arranged at intervals in sequence in the first direction. The multiple common electrode units are disposed at intersections of the multiple scan lines and the multiple common-voltage signal lines respectively. Common electrode units in a same column are all electrically coupled with a same common-voltage signal line. Common electrode units in a same row are all electrically coupled with a same second scan line.

  • Patent number: 10919786
    Abstract: Implementations herein relate to a method for preparing organic-pollution-resistant ion exchange resins and application thereof. The method includes adding modified inorganic particles to prepare novel ion exchange resins containing inorganic particles modified by a parcel modifier. A weight ratio between the monomer of the ion exchange resins and the modified inorganic particles is about 0.1% to 30%. The method may increase moisture content of the resins 3 to 30% such as to improve the structures of the resins, and therefore increase the regeneration efficiency 0.4 to 70%, as compared to conventions resins. The method improves resistance of resins to organic pollution, increases regeneration efficiency, and extends service life of the resins. In the process of water treatment, the ion exchange resin of the implementations may be regenerated with long-term stability. In addition to securing the water treatment efficiency, the method may avoid frequent replacement operations and lower the costs.

  • Patent number: 10010862
    Abstract: Implementations herein relate to a method for extraction of phthalates using hydrophilic magnetic resins with high specific surface areas. The implementations relate to a technical field of preparation of resins for fast enrichment and separation of trace organics in water. By adding magnetic particles, precursor resins may be prepared using divinylbenzene, vinyl benzoate and glycidyl methacrylate copolymerization ester. After the cross-linking reaction, surface areas of the resins are increased and hydrolysis of the ester group in alkaline solution may be implemented to obtain high specific surface magnetic resins rich in hydroxyl groups. The resins have higher adsorptive capacity and selectivity to adsorb phthalates in water samples. Rapid extraction may be implemented using magnetic solid phase extraction rod to achieve enrichment and separation of phthalates in a large amount of water samples.
