The liquid crystal display 10 includes a data driver 丨丨, a scan driver 13 and a liquid crystal panel 15 . The liquid crystal panel 15 includes a plurality of parallel lines which are parallel to each other and intersect with the sweep (four) 151 vertical insulation. The data line 153 and the complex image, the line 151 and the complex data line 153 are vertically insulated to form a complex image, the unit 150. Each of the pixel units 15A includes a thin film transistor 155 and a liquid crystal capacitor I" at the intersection of the scan line 镛 and the feed line 153. The scan driver 13 supplies a scan voltage to the plurality of scan lines 151 to form a thin film. The opening and closing of the transistor 155. The complex data driving benefit 11 provides the data signal for the complex data line 153. With the development of the liquid crystal display technology, the requirements for the display resolution are getting higher and higher. For example, a liquid crystal display having a degree of 1024 < 768, the number of data lines 153 and scanning lines 151 required are respectively "Me strips and 768 strips. Since the number of data lines I" driven by each data driver u is limited Therefore, the liquid crystal display 1 requires a larger number of data drivers 7 1364612 1 and the price of the data driver u is higher, resulting in the liquid crystal display (4). In particular, the number of the data lines 153 is much larger than the scanning line 151. See the liquid crystal display. There is more data driver 11 required, which makes the liquid crystal display 10 more expensive.
