ABSTRACT:
Disclosed relates to a method and an apparatus for converting gradation data for a color STN-LCD, capable of providing color moving pictures of excellent quality. The apparatus includes a storage buffer31for storing input data for driving the LCD, and a frame memory32for storing gradation data for driving the LCD panel. A data conversion unit33converts gradation data stored in the storage buffer140based on the gradation data stored in the frame memory, i.e., previous gradation data that was used for driving the LCD. The data conversion unit33subtracts the gradation data stored in the frame memory32from the input data stored in the storage buffer31, multiplies the subtracted result by a predetermined factor to generate a correction value, and adds the correction value to the previous gradation data to generate new gradation data. The generated gradation data is stored in the frame memory32as new gradation data.
