Abstract: A liquid crystal display device includes a source device that outputs image data and a sink device that performs a displaying operation based on the image data. The source device changes a frame rate of an image frame composing the image data while the displaying operation is performed. The sink device changes a frame rate of a panel driving frame for the displaying operation by adjusting a vertical blank period of the panel driving frame as the frame rate of the image frame is changed. Here, the sink device adjusts a common voltage applied to a display panel included in the sink device during a display operation of an individual frame, in accordance with the frame rate of the panel driving frame.

Abstract: A display apparatus includes a display panel, a gate driver and a data driver. The display panel is configured to display an image. The gate driver is configured to output a gate signal to the display panel. The data driver is configured to output a data voltage to the display panel. The display panel includes a first subpixel row including first subpixels having a first color and a second subpixel row including second subpixels having a second color. A first gate off voltage of a first gate signal applied to the first subpixel row to turn off switching elements of the first subpixel row is different from a second gate off voltage of a second gate signal applied to the second subpixel row to turn off switching elements of the second subpixel row.

Abstract: A method of adjusting luminance of a backlight unit included in a liquid crystal display device that performs inversion driving is provided. The method derives a positive polarity histogram and a negative polarity histogram of an image frame based on image frame data, corresponding to the image frame, and a data polarity pattern for implementing the image frame, derives a luminance compensation value according to data polarity dominance of the image frame by analyzing the positive polarity histogram and the negative polarity histogram, and applies the luminance compensation value to the luminance of the backlight unit during a portion of a time period of the image frame.
