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 and to compare a number of transitions between the current data and a next data to determine whether or not the current data is to be inverted in accordance with a comparison result thereof, and to determine whether or not the current data is to be inverted in accordance with a high level number difference of the data, thereby generating a reverse signal when the current data is inverted, a memory to store a data from the data transition part, 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.
