发明名称 Liquid crystal display device and method having motion picture display performance improved by proper selection of the writing time of a reset signal
摘要 <p>A source driver 12 outputs a data signal and a reset (black) signal alternately to a source line S. Four-hundred and eighty gate lines G are divided into three groups each comprising 160 lines, and connected to gate drivers 13a - 13c. A display control section 20 outputs a discriminant signal, a scan start signal and a clock signal to the gate drivers 13, where the nth gate line G is selected with the data signal outputted by the source driver 12, and where the (n+160)th gate line G is selected with the reset signal outputted. Further, n is shifted sequentially. By writing the reset signal during the latter 1/3 of one frame like this, light leakage of pixels that are changed over from white display to black display is eliminated. Also, blurs of edge portions of a motion picture are reduced. Thus, display grade for motion pictures is enhanced with a minimum improvement. &lt;IMAGE&gt;</p>
