  • Patent number: 10453418
    Abstract: A display apparatus includes a timing controller, a common voltage generator, a data driver, and a display panel. The timing controller determines a representative grayscale of each frame based on input image data and generates a common voltage control signal having a first digital value ratio (“DVR”) value corresponding to a first frame, a representative grayscale of the first frame being included in a first grayscale range. The common voltage generator generates a first common voltage based on the common voltage control signal. The data driver generates a data voltage based on the input image data. The display panel displays an image corresponding to the first frame based on the data voltage and the first common voltage.

  • Publication number: 20150288088
    Abstract: An electrical connection unit includes a first electrical connection part and a second electrical connection part combined with the first electrical connection part. The first electrical connection part includes a first signal pin configured to transmit an electrical control signal, and a first ground pin configured to receive a ground voltage, the first ground pin being longer than the first signal pin. The second electrical connection part includes a second signal pin and a second ground pin, the second signal pin facing the first signal pin and being electrically connected to the first signal pin, the second ground pin facing the first ground pin and being electrically connected to the first ground pin. An electrical over-stress may be quickly discharged using the aforementioned electrical connection unit. Accordingly, the reliability of a display device including the electrical connection unit may be improved.
