Patent ID: 7061464

Claim:
A liquid crystal display (LCD), comprising: a data storing device, which stores present input data and which outputs previously stored present input data as previous input data; a look-up table device that stores a predetermined number of values, each of which represents a preset analog voltage value, for storing corrected present input data and corrected previous input data, each of which corresponds to the present input data and the previous input data; a controller that: generates first and second load signals, stores a first present input data in the data storing device, reads out a first previous input data from the data storing device, converts the first present input data and the first previous input data into a first corrected present input data and a first corrected previous input data with reference to the look-up table device, calculates a mean value of the first corrected present input data and the first corrected previous input data, replaces the calculated mean value with a value approximating an original gray scale data value, and outputs the replaced value as pre-charge data; and a liquid crystal driver that converts the pre-charge data into analog signals and generating liquid crystal driving signals based on the converted analog signals in response to the first and second load signals.
