  • Patent number: 11972717
    Abstract: Embodiments of the present disclosure provide a method of driving display, and a display device. The method of driving display includes: scanning, progressively or rows by rows, a plurality of sub-pixels arranged in an N×M array, to turn on each row of sub-pixels scanned, so that a duration in which two adjacent rows of sub-pixels are simultaneously in an ON state is greater than or equal to two times a unit scanning time, wherein the unit scanning time is a time required for scanning a row of sub-pixels, N is an integer greater than 1, and M is an integer greater than 1; and applying data signals to at least two rows of sub-pixels simultaneously in the ON state, so that a duration of applying the data signals to each row of sub-pixels is greater than the unit scanning time.

  • Publication number: 20230340362
    Abstract: The present disclosure relates to a polymerizable surfactant with reducibility and a preparation method thereof. The acid anhydride is reacted with a long-chain fatty alcohol to obtain an intermediate of an anhydride monoester, and then the obtained intermediate is reacted with the hydrochloride of dimethylaminohalogenated alkane, and a polymerizable surfactant with reducibility is obtained by post-processing. The polymerizable surfactant can not only play a role as a reactive emulsifier and copolymerize with monomers to obtain a soap-free emulsion, but also form a redox initiation system with peroxide, and conduct redox emulsion polymerization at room temperature.

  • Patent number: 11377511
    Abstract: A reducing agent monomer for preparing a styrene-acrylic emulsion by an oxidation-reduction reaction at room temperature and a synthesis method thereof are disclosed. Maleic anhydride (MAH) and dimethylethanolamine (DMEA) are used as raw materials to synthesize the reducing agent monomer: 4-(2-(dimethylamino)ethoxy)-4-oxobut-2-enoic acid, and the synthesis method involves inexpensive easily-available raw materials, simple synthesis conditions, and easy purification. With the synthesized reducing agent monomer as a reducing agent, potassium persulfate (KPS) as an oxidizing agent, water as a dispersion medium, sodium dodecyl sulfate (SDS) as an emulsifier, and styrene, butyl acrylate (BA), and methylmethacrylate (MMA) as comonomers, free-radical microemulsion polymerization is conducted at room temperature to obtain a styrene-acrylic emulsion.
