摘要
An exemplary liquid crystal display (200) includes a data circuit (230), a timing control and video output unit (210). The timing control and video output unit includes an image edge enhancement circuit (211) configured for sharpening at least one edge of an image shown by the liquid crystal display, and a converter (212). The image edge enhancement circuit includes a color adjusting unit (214) and a brightness comparison unit (213). The color adjusting unit configured for receiving and adjusting Cb, Cr color factors of the YCbCr image signals according to a result of comparison of brightness factors Y of the YCbCr image signals received from the brightness comparison unit. The adjusted YCbCr image signal is converted to a corresponding RGB signals by the converter circuit and the RGB signals are sent to the data driving circuit.
