  • Sweep voltage generator and display panel
    Patent number: 11967272
    Abstract: A sweep voltage generator and a display panel are provided. The sweep voltage generator includes an output node, a current generating block and a voltage regulating block. The output node is used to provide a sweep signal. The current generating block is coupled to the output node, includes a detection path for detecting an output load variation on the output node, and adjusts the sweep signal provided by the output node based on the output load variation. The voltage regulating block is coupled to the output node for regulating a voltage of the output node.
