Abstract
The invention provides a liquid crystal display panel. The liquid crystal display panel comprises multiple scanning lines and multiple USB cables, and the scanning lines and the USB cables are arranged in a criss-cross pattern. The liquid crystal display panel is characterized by further comprising one virtual scanning line which is arranged between two scanning lines in the middle of the multiple scanning lines, and the virtual scanning line is parallel to the scanning line. According to the liquid crystal display panel, the virtual scanning line is added and designed between the two scanning lines in the middle of the liquid crystal display panel, and thus signal differences influenced by two pixel coupling capacitance can be avoided. The liquid crystal display panel solves the problem that the pixel can be fully charged only by adopting bidirectional scanning driving pattern; meanwhile, the liquid crystal display panel guarantees that obtained pictures are not distorted.
