Description

Array substrate, driving method and display device Technical Field The invention relates to the technical field of displays, in particular to an array substrate, a driving method and a display device. Background With the development of science and technology, an LCD (Liquid CRYSTAL DISPLAY ) display has replaced a heavy CRT display, and has been increasingly used in daily life, especially in LCD displays, which have features of small size, light weight, thin thickness, low power consumption, no radiation, etc., and have been rapidly developed in recent years, and have been mainly used in the current flat panel display market, and have been widely used in various products of large, medium and small sizes, almost covering the fields of today's information society, such as Liquid crystal televisions, computers, mobile phones, PDAs, GPS, vehicle-mounted displays, projection displays, video cameras, digital cameras, electronic watches, calculators, electronic instruments, meters, public displays, and phantom displays. In the image display process, each liquid crystal pixel point in the LCD panel display is driven by a thin film transistor (Thin Film Transistor, abbreviated as TFT) integrated in a TFT thin film transistor array substrate, and then is matched with a peripheral driving circuit to realize image display. The LCD with dual-gate structure is a structure that is commonly used at present because it can reduce the number of data lines and increase the aperture ratio. Fig. 1 is a schematic waveform diagram of a scan signal and a data signal during two-dot inversion in the first prior art, fig. 2 is a schematic polarity diagram of an array substrate during two-dot inversion in the first prior art, and fig. 3 is a schematic layout structure of R/G/B pixels in the first prior art. As shown in fig. 1 to 3, in the LCD product of the dual gate structure in the first prior art, the data signal only needs to be switched once every frame during the dual dot inversion, but the image quality of the dual dot inversion is poor although the power consumption can be saved. Fig. 4 is a schematic waveform diagram of a scan signal and a data signal during single-point inversion in the first prior art, and fig. 5 is a schematic polarity diagram of the array substrate during single-point inversion in the first prior art. As shown in fig. 4 and 5, in order to realize better single-dot inversion, the data signal needs to be inverted once every scanning line, and although a single-dot inversion effect of better image quality can be realized, the switching frequency of the data signal is too fast, and the driving power consumption increases. Moreover, in one such architecture of the prior art, the source line of a portion of the pixels needs to be lengthened, resulting in a larger resistance and parasitic capacitance, and thus loading becomes larger. Fig. 6 is a schematic waveform diagram of a scan signal and a data signal during double-row inversion in the second prior art, fig. 7 is a schematic polarity diagram of the array substrate during double-row inversion in the second prior art, and fig. 8 is a schematic layout diagram of R/G/B pixels in the second prior art. As shown in fig. 6 to 8, in order to reduce the problem of the large resistance and parasitic capacitance of the first prior art architecture, the second prior art architecture adopts another dual gate architecture, but when the data signal only needs to be switched once per frame, the second prior art architecture can only realize the double-column inversion, and the image quality is worse than that of the double-dot inversion and the single-dot inversion. Fig. 9 is a schematic waveform diagram of a scan signal and a data signal during two-dot inversion in the prior art, and fig. 10 is a schematic polarity diagram of an array substrate during two-dot inversion in the prior art. As shown in fig. 9 and 10, in the two-dot inversion of the related art, the data signal needs to be inverted once every two scanning lines, and the switching frequency of the data signal is too fast and the driving power consumption is large although the image quality is good compared with the double-row inversion. Fig. 11 is a schematic waveform diagram of a scan signal and a data signal during single-point inversion in the second prior art, and fig. 12 is a schematic polarity diagram of the array substrate during single-point inversion in the second prior art. As shown in fig. 11 and 12, in the second conventional technique, the data signal needs to be inverted once every scanning of one scanning line, and the single-point inversion effect of good image quality can be achieved, but the switching frequency of the data signal is faster and the driving power consumption is larger. Disclosure of Invention In order to overcome the defects and shortcomings in the prior art, the invention aims to provide an array substrate, a driving method and a display device, so as to solve the problems of lar
