  • Display device and driving method
    Patent number: 12374291
    Abstract: Embodiments of the disclosure relate to a display device and a method for driving the same and, specifically, may stably supply current to the driving voltage line by controlling the output current by the first gain when the difference in magnitude between the sensing current and the target current is larger than the reference data and controlling the output current by the second gain when the difference in magnitude between the sensing current and the target current is the reference data or less.
    Type: Grant
    Filed: February 22, 2024
    Date of Patent: July 29, 2025
    Assignee: LG Display Co., Ltd.
    Inventors: YongKyu Park, JaeKook Ahn
  • Display device and driving method
