Abstract: A display apparatus includes a display panel. The display panel includes a high sub-pixel, a low sub-pixel and a toggle voltage input circuit. The high sub-pixel may include a first switching element connected to a gate line extending in a first direction and a data line extending in a second direction crossing with the first direction. The low sub-pixel may include a second switching element connected to the gate line and the data line and disposed opposite to the high sub-pixel with reference to the gate line, and a third switching element connected to the second switching element and a storage line. The toggle voltage input circuit may be connected to the storage line to transmit a toggle voltage to the low sub-pixel. The toggle voltage may be capable of being varied periodically.

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.
