  • Power supply and display device including the same
    Patent number: 11164529
    Abstract: A power supply includes a boost circuit having a first boost circuit configured to output a first driving voltage to be supplied to the display panel by stepping unit an input voltage and a second boost circuit configured to output a second driving voltage to be supplied to the display panel by stepping down the input voltage, and a correction circuit configured to output a correction signal based on a result obtained by sensing the input voltage, and controls output efficiency of the boost circuit based on the input voltage and current sensed from the display panel.
    Type: Grant
    Filed: May 28, 2020
    Date of Patent: November 2, 2021
    Assignee: LG DISPLAY CO., LTD.
    Inventors: Nak-Yoon Kim, Ji-Su Kim, Hong-Soon Kim

  • Driving circuit for display device and method of driving the same
    Patent number: 9330618
    Abstract: A driving circuit for a display device, for reducing power consumption of a data driver, and a method of driving the driving circuit are disclosed. The driving circuit includes a data driver for maintaining buffers of the data driver in an on state every preset specific frame period and maintaining the buffers in an off state every remaining period except for specific frame periods in a refresh mode for processing image data of one image for the specific frame periods only.
