Abstract:
1. A liquid crystal display, comprising: a liquid crystal display panel including a plurality of data lines, a plurality of gate lines crossing the data lines, and a plurality of liquid crystal cells; a data driving circuit for supplying data voltages to the data lines; a gate driving circuit for supplying gate pulses to the gate lines; a timing controller for supplying data to the data driving circuit and controlling the data driving circuit and the gate driving circuit; and an over-driving controller which, if a difference between input data input during a (N)th frame period (N is a positive integer) and (N−1)th frame data read from a memory is 2 gray levels or more, modulates the data at an over/under shoot ratio of 20% to 80% and supplies the modulated data to the timing controller, if the difference is less than 2 gray levels, supplies the input data to the timing controller, and differently converts a least significant bit of the data stored in the memory according to whether or not the data is modulated, wherein if the data difference during the (N)th frame period is two gray scales or more, the over-driving controller supplies the data modulated at 20% to 80% to the timing controller and converts only the least significant bit in the modulated data to ‘1’ and stores the same in the memory.
