1. A liquid crystal display device comprising:
a liquid crystal display panel including a plurality of gate lines and a plurality of data lines; a data driver configured to apply data voltages to the data lines; a gate driver configured to apply gate pulses to the gate lines; and a charge share device configured to selectively perform a charge share operation, the charge share device comprising:
a line memory configured to store first video data from a first interval, the first video data comprising a first entire gray level of a first data line during the first interval and a second entire gray level of a second data line during the first interval;a determiner configured to:
receive second video data from a second interval, the second video data comprising a third entire gray level of the first data line during the second interval and a fourth entire gray level of the second data line during the second interval;determine at least two differences between entire gray levels of the first video data and entire gray levels of the second video data, the differences comprising a first difference between the first entire gray level and the third entire gray level and a second difference between the second entire gray level and the fourth entire gray level,detect a number of the at least two differences that are not less than a first non-zero reference gray level, andoutput a charge share signal in response to the detected number of the at least two differences that are not less than the first non-zero reference gray level; andone or more charge sharers configured to:
store charges corresponding to a bias voltage in response to the first video data during the first interval, andprovide, in response to the charge share signal, the stored charges to even or odd-numbered data lines in response to the second video data during the second interval. |
