    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.
