  • Patent number: 11699388
    Abstract: A display device includes: a display panel including pixels emitting light, based on a data voltage; a current limiter for determining a scale factor by comparing a previous frame load with a predetermined threshold load, and generating compensated image data by applying the scale factor to current image data as input image data of a current frame to adjust the data voltage; and a data driver for converting the compensated image data into the data voltage and providing the data voltage to the display panel.
    Type: Grant
    Filed: February 2, 2022
    Date of Patent: July 11, 2023

  • Patent number: 9930770
    Abstract: A printed circuit board (“PCB”) includes a first pattern structure, a second pattern structure, a third pattern structure, and a fourth pattern structure. The first pattern structure includes a first ground pattern. The second pattern structure includes a first line pattern overlapping the first ground pattern and a second ground pattern electrically insulated from the first line pattern. The third pattern structure includes a third ground pattern overlapping the first line pattern and a second line pattern overlapping the second ground pattern. The fourth pattern structure includes a fourth ground pattern overlapping the second line pattern. Therefore, the PCB may decrease noise.

  • Publication number: 20130088480
    Abstract: A gate driver receiving a low voltage without an appropriate control signal in an initialization step from the time of turn-on of the power of the display device to the time of beginning of normal operation of the display device to previously generate and output a gate clock signal CPV so as to prevent a horizontal line defect from appearing. Thereby, the generated clock signals CKV and CKVB are transmitted to the gate driver such that the gate driver is appropriately controlled and the horizontal line defect is not generated.
