Abstract:
1. A liquid crystal display, comprising: a liquid crystal polarity inversion driver determining whether a polarity of a liquid crystal is inverted and inverting the polarity of the liquid crystal in accordance with the determined result; a first data inversion driver determining whether a number of transition of odd data having a plurality of bits is more than half of the plurality of bits of the odd data, and inverting the odd data in accordance with the determined result; and a second data inversion driver determining whether a number of transition of even data having a plurality of bits is more than half of the plurality of bits of the even data, and inverting the even data in accordance with the determined result, wherein the first data inversion driver includes a first data transition part determining whether a first data transition has occurred in the odd data and outputting a first signal, a first data inversion signal summer counting the number of the first signal and outputting a first REV signal having a high level or a low level according to the counted number of the first signal, and a first data inversion signal output part receiving the first REV signal from the first data inversion signal summer and outputting either the odd data or an inverted odd data according to the first REV signal, and wherein the second data inversion driver includes a second data transition part determining whether a second data transition has occurred in the even data and outputting a second signal, a second data inversion signal summer counting the number of the second signal and outputting a second REV signal having a high level or a low level according to the counted number of the second signal, and a second data inversion signal output part receiving the second REV signal from the second data inversion signal summer and outputting the even data or an inverted even data according to the second REV signal.
