摘要： A display apparatus includes a timing controller, a data driver and a display panel. The timing controller generates a mode selection signal and output image data in response to input image data. The data driver generates first through N-th data voltages in response to the mode selection signal and the output image data and applies the first through N-th data voltages to first through N-th data lines. The display panel is connected to the first through N-th data lines. During the first operation mode, each of a polarity pattern of first through M-th data voltages and a polarity pattern of (M+1)-th through N-th data voltages repeats a first polarity pattern. During the second operation mode, the polarity pattern of the first through M-th data voltages repeats the first polarity pattern, and the polarity pattern of the (M+1)-th through N-th data voltages repeats a second polarity pattern.

摘要： A method of driving a light source includes outputting a light source driving signal and outputting a delayed driving signal. The light source driving signal drives a light source based on image data. The delayed driving signal is generated by delaying the light source driving signal based on a vertical sync signal having a frame period of the image data and a data enable signal having a horizontal line period of the image data.

摘要： A liquid crystal display and a method for driving the same. The liquid crystal display includes: gate lines arranged in a row direction; data lines arranged in a column direction; and subpixels arranged in basic units of eight subpixels. Each subpixel is each connected to one of the gate lines and one of the data lines, and the subpixels are continuously arranged along a row and are arranged in a matrix. In the basic units, polarities between adjacent subpixels from a first subpixel to a fourth subpixel along the row are opposite to each other, polarities between adjacent subpixels from a fifth subpixel to an eighth subpixel along the row are opposite to each other, and polarities of the fourth subpixel and the fifth subpixel are the same.

The pixels include pixels arranged in a k-th row and pixels arranged in a (k+1)th row disposed adjacent to the pixels arranged in the k-th row in the second direction. An (i+1)th gate line is disposed between the pixels in the k-th row and the pixels in the (k+1)th row. A first pixel arranged in a g-th column among the pixels arranged in the k-th row and a second pixel arranged in the g-th column among the pixels arranged in the (k+1)th row are connected to a j-th data line. The pixels arranged in the k-th row are alternately connected to an i-th gate line and the (i+1)th gate line.
