摘要： An exemplary liquid crystal display (LCD) provides data lines, gate lines, and pixel units arranged as a matrix array. A method for driving the LCD includes a step of analyzing and determining polarities of one column of the pixel units as determining pixels, thereby defining a first polarity group and a second polarity group, and a step of sequentially applying corresponding data signals to a part of the whole pixel units that are arranged at same rows with the first polarity group in a part of a period of a frame. Corresponding data signals are sequentially applied to the other part of the whole pixel units that are arranged at same rows with the second polarity group in another part of a period of a frame.

摘要： An exemplary liquid crystal display (3) includes a matrix-converting circuit (316) and an inverse-matrix-converting circuit (327). The matrix-converting circuit receives an RGB (red green blue) signal, and converts the RGB signal to a YCbCr signal. The inverse-matrix-converting circuit converts the YCbCr signal back to the RGB signal. The liquid crystal display requires only a relatively small amount of bandwidth for signal transmission. A related method of transmitting signals in a liquid crystal display is also provided.
