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 bufferfor storing input data for driving the LCD, and a frame memoryfor storing gradation data for driving the LCD panel. A data conversion unitconverts gradation data stored in the storage bufferbased on the gradation data stored in the frame memory, i.e., previous gradation data that was used for driving the LCD. The data conversion unitsubtracts the gradation data stored in the frame memoryfrom the input data stored in the storage buffer, 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 memoryas new gradation data.
