A method for improving motion blur and contour shadow of a display displaying images having a number of frames includes transforming a second average gray scale into a third average gray scale when a first average gray scale for displaying a first frame is unequal to the second average gray scale for displaying a second frame. A luminance corresponding to the second frame is generated according to the third average gray scale and at least one luminance query table. The third average gray scale is greater than the first average gray scale and the second average gray scale or less than the first average gray scale and the second average gray scale.

Method for improving motion blur and contour shadow of display and display thereof

An exemplary liquid crystal display () includes a data circuit (), a timing control and video output unit (). The timing control and video output unit includes an image edge enhancement circuit () configured for sharpening at least one edge of an image shown by the liquid crystal display, and a converter (). The image edge enhancement circuit includes a color adjusting unit () and a brightness comparison unit (). 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.
