  • Patent number: 11069275
    Abstract: Provided are a timing controller, and a driving method and a display device thereof. The timing controller may include a detection circuit and a control circuit. The detection circuit may detect a symbol error rate of a drive signal transmitted from a control circuit to a source drive circuit, and send the symbol error rate to the control circuit. The control circuit may automatically adjust a voltage swing of the drive signal according to the symbol error rate of the drive signal, and may enable a magnitude of the adjusted voltage swing to negatively correlate with a magnitude of the symbol error rate. Therefore, electromagnetic interference is effectively reduced, and flexibility in reducing electromagnetic interference is improved.

  • Publication number: 20210214813
    Abstract: Disclosed is a slag discharging method in a process of producing ultra-low phosphorus steel, which relates to the technical field of iron and steel smelting, and in which molten steel is mixed with lime first to produce basic slag; then converting is performed with oxygen to increase the oxidizability of the basic slag; and a carbon-containing reducing agent is finally added, so that in the process that the carbon is oxidized to release a large amount of carbon monoxide gas, phosphates are captured, and the basic slag is rapidly foamed and overflows from the opening of the steel ladle, so that conditions are no longer available for rephosphorization. The slag discharging method is simple and convenient to operate, does not have high requirements on the equipment, has relatively good dephosphorization effect, and can be used to prepare an ultra-low phosphorus steel containing less than 0.003% phosphorus.
