Patent ID: 8446395

Claim:
A liquid crystal display device, comprising: a liquid crystal display panel including a plurality of data lines, a plurality of gate lines, and a plurality of liquid crystal cells; a data drive circuit to invert a polarity of the data voltage in response to a polarity control signal and supplies the data voltage to the data lines in response to a source output enable signal; a gate drive circuit to supply a scan pulse to the gate lines; an image analyzing circuit to detect any one of interlace data and scroll data in an input image; a first controller to increase a data charge amount of the liquid crystal cell during an aging period, the aging period beginning from the time when power to drive the drive circuits is generated to a predetermined time thereafter, and to decrease the data charge amount of the liquid crystal cell at every Nth-multiple frame period (wherein N is a positive integer) using the source output enable signal when any one of the interlace data and the scroll data is detected by the image analyzing circuit during a normal drive period after the aging period; and a second controller to control the polarity of the data supplied to the liquid crystal cell at every Nth-multiple frame period to be the same as the previous frame period when any one of the interlace data and the scroll data is detected by the image analyzing circuit during the normal drive period, and to invert the polarity of the data supplied to the liquid crystal cell at all other frame periods using the polarity control signal.
