ABSTRACT:
A liquid crystal display device includes a data transition part to compare a number of transitions between a previous data and a current data to selectively invert the current data and to generate a reverse signal, a memory to store the data from the data transition part and to output the stored data as the previous frame data, a data reverse transition part to reversely convert the data from the memory using the reverse signal, a lookup table to compare the current data and the previous frame data reversely converted by the data reverse transition part to select a modulated data, and a display drive circuit to display the data from the lookup table on a liquid crystal display panel.
