  • Patent number: 10796670
    Abstract: Embodiments of the present disclosure disclose a method and device for reducing bandwidth consumption of a display controller. The method includes: whether image data of a current User Interface (UI) frame to be displayed is the same as image data of a previous UI frame is judged; when the image data of the current UI frame to be displayed is the same as the image data of the previous UI frame, image data in a nontransparent region except a transparent region of the previous UI frame is read; and when the image data of the current UI frame to be displayed is different from the image data of the previous UI frame, a transparent region of the current UI frame to be displayed is determined according to a preset strategy. Embodiments of the present disclosure further disclose a display controller and a computer storage medium.

  • Patent number: 9373950
    Abstract: The invention relates to Modular multilevel converter valve protection method, the modular multilevel converter valve consists of 6 arms, the arm includes sub modules, 1 arm is controlled by 1 control host, 6 control hosts is controlled by 1 summary control host, the method of the invention includes that the arm realizes locking sub module, bypass sub module, trip requests and system switching request and the summary control host implements summary and control response. The invention improves the reliability of two protection system through the use of dual redundancy protection method, clears the protection division through the layered protection frame of the upper summary control host and multi arm control host. And finally, it improves the whole safety and reliability of the modular multilevel converter valve.
