  • Patent number: 12293732
    Abstract: A circuit for eliminating afterimage and a display device. The circuit includes a power supply unit, an afterimage elimination unit and a discharge unit. First and second output ends of the power supply unit are connected with the afterimage elimination unit, respectively. A control end of the discharge unit is configured in electric connection with the control unit, and an execution end of the discharge unit is connected with the first output end of the power supply unit. When the screen is turned off, the control unit outputs a first control signal to the discharge unit. The discharge unit discharges at the first output end of the power supply unit according to the first control signal, so as to expedite a falling of the first voltage output from the first output end of the power supply unit.

  • Patent number: 11920031
    Abstract: Disclosed is a high ultraviolet blocking polylactic acid composite material reinforced by POSS modified bamboo powder. The preparation method therefor includes steps of carrying out chemical grafting modification of bamboo powder with proper particle size by using POSS containing specific organic groups, and then adding the modified bamboo powder to polylactic acid for melting and co-extrusion to obtain POSS modified bamboo powder. The present disclosure makes full use of the 30% lignin in the bamboo powder, having the advantages of wide source, biological metabolizability and low price; the present disclosure does not need the traditional inorganic ultraviolet blocking agent, nor need to extract refined lignin from natural materials, but directly takes inexpensive and easy-to-obtain bamboo powder as main raw material. The composite material prepared in the present disclosure can greatly improve the UV blocking performance, mechanical properties and thermal stability of the PLA.
