  • Publication number: 20240233652
    Abstract: A source driving circuit includes a first source driver and a second source driver. The first source driver is configured to convert latched first image data into a plurality of first data voltages in response to a first triggering moment of a first data transmission control signal, and output the plurality of first data voltages based on a second triggering moment of the first data transmission control signal. The second source driver is configured to convert latched second image data into a plurality of second data voltages in response to a first triggering moment of a second data transmission control signal, and output the plurality of second data voltages based on a second triggering moment of the second data transmission control signal. The second triggering moment of the first data transmission control signal and the second triggering moment of the second data transmission control signal have a time difference.

  • Patent number: 8789319
    Abstract: A seismic-incurred-rupture-resistant deformation-recordable buckling-restrained brace is disclosed. A core plate is disposed in the concrete filled steel tubular outer sleeve, and an end portion of the core plate is provided with a core plate stiffening rib. A brace deformation recording device includes two toothed racks, a ratchet gear, a first cord spool, and a second cord spool. The two toothed racks are fixed on the core plate stiffening rib, and ratchet pawls in the length direction thereof face opposite directions. The ratchet gear is fixedly connected to the concrete filled steel tubular outer sleeve. The ratchet gear is disposed between the two toothed racks. A tooth on the ratchet gear is engaged with a ratchet pawl. The first cord spool is fixed on the ratchet gear. The second cord spool is fixed on the core plate stiffening rib.
