  • Display apparatus and method of driving the same
    Patent number: 9741298
    Abstract: A display apparatus includes a display panel which displays an image, a timing controller which determines an inversion driving method of the display panel based on a waveform of a fed back common voltage from the display panel, and a data driver which outputs a data voltage to the display panel according to the inversion driving method.
    Type: Grant

  • LIQUID CRYSTAL DISPLAY DEVICE
    Publication number: 20160140920
    Abstract: A liquid crystal display device and a method of driving a liquid crystal display device are provided. The liquid crystal display device includes a display panel, a controller configured to generate and output an inversion switch signal for controlling inversion driving of the display panel by receiving a common voltage fed back from the display panel, and a data driver configured to receive the inversion switch signal and switch an inversion driving scheme. The controller includes a waveform converter for converting the common voltage to a square wave.
