Patent number: 10464812Abstract: Provided is a method for catalytically reducing selenium. Hydrogen peroxide is used as a catalyst, and a reducer is added to a hexavalent-selenium-containing solution for reaction so as to reduce the selenium to elemental selenium, wherein the standard oxidation-reduction potential of the reducer is lower than the standard oxidation-reduction potential of the conversion of the hexavalent selenium to elemental selenium. The present method can further reduce a hexavalent-selenium element-containing selenic acid or selenate solution to an elemental selenium product in one step.Type: GrantFiled: March 30, 2017Date of Patent: November 5, 2019Assignee: Central South UniversityInventors: Xueyi Guo, Runze Xu, Dong Li, Qinghua Tian

The LCD panel includes a timing controller, a GOA signal controller and a panel main body, the GOA signal controller being connected to the panel main body via second circuit line. The GOA signal controller is used for shifting a level of received timing control signal outputted by the timing controller and sending level-shifted control signal to the panel main body, monitoring current of level-shifted control signal transmitted on second circuit line, and sending notification signal to the timing controller when current of level-shifted control signal exceeds a set threshold current. The timing controller is used for stopping outputting the timing control signal to the GOA signal controller when notification signal is captured, so that the GOA signal controller stops outputting level-shifted control signal. This application prevents risks resulted from short circuit in LCD panels.Type: ApplicationFiled: May 8, 2017Publication date: May 31, 2018Inventor: QINGHUA TIAN
