    Abstract: A display apparatus includes a liquid crystal panel including gate lines, data lines, and pixels, a gate driver, a data driver, and a timing controller. The pixels include first and second pixels. The first and second pixels are arranged in pixel rows adjacent to each other, arranged in different pixel columns, connected to the same gate line, display the same color, and receive data voltages having different polarities from each other. The image data include first pixel data displayed in the first pixels and second pixel data displayed in the second pixels. When the first pixel data have a first grayscale value and the second pixel data have a second grayscale value different from the first grayscale value, the timing controller modulates the first and second pixel data to allow the first and second pixel data to have a grayscale value between the first and second grayscale values.

    Abstract: A display apparatus includes gate lines configured to receive gate signals, data lines arranged to cross the gate lines and configured to receive data voltages, and pixels grouped into first pixel groups and second pixel groups and connected to the gate lines and the data lines. The gate signals are configured to be applied to the gate lines in a predetermined order while skipping at least one gate line without being sequentially and consecutively applied to two gate lines adjacent to each other among the gate lines.

    Abstract translation: 显示装置包括被配置为接收栅极信号的栅极线，布置成跨越栅极线并被配置为接收数据电压的数据线，以及被分组为第一像素组和第二像素组并连接到栅极线和数据线的像素。 栅极信号被配置为以预定顺序施加到栅极线，同时跳过至少一个栅极线而不是顺序地并连续地施加到栅极线之间彼此相邻的两个栅极线。
