  • Publication number: 20230282166
    Abstract: A display panel and a drive circuit of the same are provided. The drive circuit includes multiple drive circuit rows. Each of the drive circuit rows includes multiple pixel drive circuits and a signal processing circuit. According to the drive circuit, a signal processing circuit can obtain a drive signal by processing a scan signal and a light-emitting control signal of a drive circuit row to which the signal processing circuit belongs, and can output the drive signal to each pixel drive circuit in the drive circuit row to which the signal processing circuit belongs; a pixel drive circuit can form a capacitor-reset loop by multiplexing a first switch tube in a light-emitting element reset loop of the pixel drive circuit, a second switch tube in a data-writing loop of the pixel drive circuit, and a third switch tube in a light-emitting loop of the pixel drive circuit.

  • Patent number: 10385619
    Abstract: Specialized computing systems, devices, interfaces and methods facilitate the simulation of downhole milling procedures such as wellbore departure milling procedures. Computing systems, devices, interfaces and methods enable a user to design and select milling components and procedures to be compared and simulated. Various milling parameters, such as milling tool parameters, whipstock parameters, and wellbore casing parameters may be accessed and selectably modified with milling and simulation interfaces to define and control the simulated milling procedures. Different types of output are selectably rendered to reflect various aspects of the simulated milling procedures.
