Abstract: A display apparatus includes a local dimmer, an image compensator, a display panel and a light source. The local dimmer is configured to generate a dimming signal representing a degree of dimming for a light source block based on input image data. The image compensator is configured to determine a grayscale gain based on input grayscale value of the input image data and the dimming signal and to compensate luminance of the input image data based on the grayscale gain. The display panel is configured to display an image based on the compensated input image data. The light source is configured to provide light to the display panel based on the dimming signal.

Abstract: A display apparatus includes gate lines extending in a first direction, data lines crossing the first direction and having polarities of data voltages consecutively repeated every four data lines, and pixels which each comprise three sub-pixels. One of the three sub-pixels has a width in the first direction different from a width in the first direction of another sub-pixel of the three sub-pixels. Each of the three sub-pixels is connected to a corresponding gate line and a corresponding data line. The polarities of the data voltages applied to a first data line and a third data line are opposite and the polarities of the data voltages applied to a second data line and a fourth data line are opposite. The pixels arranged between two adjacent data lines among the plurality of data lines are alternately connected to the two adjacent data lines.
