<p>Disclosed relates to a method and an apparatus for converting gradation data in LCD that provides a high response of LCD by converting gradation data applied to LCD appropriately. According to the present invention, a data converting part 32 converts gradation data, newly input and stored in a recording buffer 31, based on previous gradation data stored in a frame memory 33 and, the converted gradation data, i.e., the gradation data to be displayed newly on the LCD, is stored in the frame memory 33. Especially, the data converting part 32 executes gradation conversion based on the gradation levels that input gradation data and previous gradation data have. Accordingly, the prevent invention can raise the response of the LCD all the more by executing most optimum gradation conversion in accordance with characteristics of the LCD and, further, removes after-images shown on the LCD efficiently.</p> |
