Abstract:
1. A liquid crystal display device comprising: a plurality of liquid crystal display panels; a timing controller to control outputting timing of a plurality of image data signals, said image data signals each being fed to a corresponding one of said plurality of liquid crystal display panels; a source driver to output image data, gate line by gate line, to a plurality of drain lines commonly connected between said source driver and each of said plurality of liquid crystal display panels according to output timing control exercised by said timing controller; and a plurality of gate drivers each corresponding to one of said plurality of liquid crystal display panels, said gate drivers each outputting sequentially gate driving pulses to a plurality of the gate lines connected to the corresponding liquid crystal display panel according to inputting of first and second signals, the first signal, which is fed sequentially to said plurality of gate drivers in a cascaded manner, providing instructions for a start of outputting of the corresponding image data signal, which is transmitted from said timing controller, to be fed to the corresponding liquid crystal display panel, and the second signal, which is fed to said plurality of gate drivers in a parallel manner, controlling an inputting period of frame by frame image data, which makes up the corresponding image data signal; wherein a plurality of the frame-by-frame image data, which makes up said plurality of image data signals, each is sequentially switched in order of inputting of said plurality of the frame-by-frame image data and is output to the drain lines connected to the corresponding liquid crystal display panel.
