Abstract
A method of driving a liquid crystal display device includes inputting source image data, each of which has one of m gray level values, wherein m is a natural number, defining T error data from the source image data, wherein the error data have top k gray level values, and T and k are a natural number, generating conversion image data having larger gray level values than the source image data using one having a largest gray level value from the source image data excluding the error data, inputting the conversion image data to a liquid crystal panel, controlling a brightness of a backlight unit in accordance with the conversion image data, forming a bitmap corresponding to the conversion image data, wherein the bitmap shows positional distribution of pixels with the error data, counting error areas by scanning the bitmap, wherein each of the error areas includes the predetermined number of the pixels having the error data, and controlling the T according to the number of the error.
