Abstract:
1. A liquid crystal display device comprising: a timing control unit for generating a first control signal and a second control signal which are transitioned in state every ½ frame, the timing control unit having a counter unit for outputting a polarity signal according to a count number based on the occurrence of rising or falling edges of at least one of the first and second control signals and restarting to count after two frames; a substrate; a plurality of gate lines arranged on said substrate in a first direction; a plurality of data lines arranged on said substrate in a second direction and crossing said plurality of gate lines to form a plurality of regions bordered by two gate lines and two data lines; a plurality of pixels arranged on said substrate, two of said plurality of pixels being provided in each region of said plurality of regions, an odd numbered pixel of an odd numbered row is connected to an even numbered gate line and an even numbered pixel of the odd numbered row is connected to an odd numbered gate line, and odd numbered pixel of an even numbered row is connected to an odd numbered gate line and an even numbered pixel of the even numbered row is connected to an even numbered gate line; and a data driving unit for determining polarities of first image data and second image data according to the polarity signal received from said timing control unit, said data driving unit supplying the first image data to a first set of pixels of an odd numbered column through an odd numbered data line and supplying the second image data to a second set of pixels of an even numbered column through an even numbered data line, wherein each pixel is coupled to a first switching device for receiving image data from said data driving unit, and a second switching device for receiving image data through said first switching device and for supplying the image data to an associated pixel, wherein a first switching device of the odd numbered pixel of the odd numbered row and a first switching device of the even numbered pixel of the even numbered row include a gate electrode connected to the even numbered gate line, and a first switching device of the even numbered pixel of the odd numbered row and a first switching device of the odd numbered pixel of the even numbered row include a gate electrode connected to the odd numbered gate line, wherein said first switching device is turned on by a scan signal supplied through one of said plurality of gate lines, and said second switching device is turned on by the first control signal or the second control signal, and wherein a first control signal line receives the first control signal from said timing control unit and is connected to the pixels of the first set through said second switching device, and a second control signal line receives the second control signal from said timing control unit and is connected to the pixels of the second set through said second switching device.
