[Prior Art] Liquid crystal displays use their thin, lightweight, low-power consumption and environmental burdens, and they have a high occupancy rate in all areas. The dynamic matrix drive circuit controls the operation of the repentance panel, and with the vigorous development of the display technology, how to improve the display quality and reduce the cost is the two major problems that the industry has been trying to overcome. Because the molecular characteristics of the liquid crystal cannot fix the electric field of the same polarity for too long, if the time is too long, even if the voltage is removed, the liquid crystal molecules will not be able to rotate according to the change of the electric field due to the destruction of the characteristics, so as to form the corresponding gray. Order. Therefore, at regular intervals, the polarity of the voltage applied to the liquid crystal molecules must be switched to prevent the properties of the liquid crystal molecules from being destroyed. When the kneading surface does not move, that is to say, the kneading surface always shows the same gray level, for the liquid crystal display, the display voltage in the liquid crystal display is divided into two polarities, one is defined as positive polarity, and the other is Negative polarity. When the voltage of the display electrode is higher than the voltage of the Vc 〇 mm 〇 n electrode, it is called positive polarity. When the voltage of the display electrode is lower than the voltage of the Vc 〇 mm 〇 n electrode, it is called negative polarity. Whether it is positive or negative, there will be a set of gray levels of the same brightness. Therefore, when the absolute value of the pressure difference between the upper and lower layers of glass is fixed, whether the voltage of the display electrode is high or the voltage of the common electrode is high, the gray scale is exactly the same. However, in both cases, the steering of the liquid crystal molecules is completely reversed, and the above-described deterioration of the characteristics caused when the liquid crystal molecules are always fixed in one direction can be avoided. That is to say, when the display screen is not moving, it is still possible to achieve the result that the display screen is not moved by the alternating of the positive and negative polarities 5 201024876, and the liquid crystal molecules are not destroyed. So when you look at the _ liquid _ 面 杂 杂 , , , , , 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实 其实The panel changes in various polarities, but the polarity is changed the next time the screen data is changed. For the same point, its polarity is constantly changing. Whether the adjacent points have phase_polarity can be determined according to the non-polarity conversion method.纟 ’ ' Nowadays it is common to use the LCD on the individual, the panel used dot inversion ^ line inversion > column ❹丨nversion, frame inversi〇n. Each polarity change has its own advantages and disadvantages. The following describes the problems encountered in the prior art when using the frame lnversi〇n polarity transform. The schematic diagram of the general active matrix driving circuit is shown in the first figure, which is designed by gamma inversion. In the active matrix type liquid crystal display panel 24, each pixel has a thin film transistor (TFT) 12 as a switch, and its gate is connected to a horizontal scanning line 14 to a vertical data line 16, and the source is connected. The pole is connected to the liquid crystal electrode as shown in the figure. The display panel simultaneously initiates a horizontal line 14 at the same time to cause all of the thin-film wires 12 (10) on the line to be fed vertically into line 16 into the corresponding element 1 . Next, the thin film transistor 12, until the next time the input signal is rewritten, during which the charge is stored on the pixel capacitor ;; at this time, the next scan line is activated to input the data signal to the corresponding pixel via the data line; Write the data signal of the entire screen in sequence, and then re-write the signal from the first line. The plurality of data lines 16 are driven by the data driver 20, and the plurality of scan lines 14 are driven by the scan driver 22, so that each pixel in the active matrix display panel can be controlled to operate according to the input data signal. Display the image on the display panel. The first-囷 system uses RGB pixels to represent the schematic circle of the general active matrix slid circuit. From the point of view of the first picture as RGB pixels, the second picture can be used to display 2400 pixel TFTs for each scanning line, and the pixels in each scanning line are R, g, b as a 6 201024876 Cycles are arranged interactively. The first picture and the second picture introduced above belong to one of S|ng丨eGate. For Single Gate, the extreme performance of RGB pixels is presented in the form of frame inversi〇n, that is, the polarity of each point and itself. The adjacent up, down, left, and right points are the same polarity. Taking frame inversion as an example, the polarity of each element is the same as the pixels above and below it. Please refer to the second and third circles at the same time. The waveform of the clock signal and the gate signal in the second figure of the third circle . Where YDI01 represents the first trigger signal, YCLK is the clock signal, YOE is the interval signal, G1-G256 is the gate signal, yD|〇2 represents the second trigger #, and there is a delay between each signal. The time t is used to separate from each other to avoid β β. From the second figure, it can be found that the prior art G1 to G256 are sequentially scanned from top to bottom. In order to improve the picture quality of a liquid crystal display panel, it is necessary to pay sufficient attention to the problem of the differential pressure between the upper and lower layers of the liquid crystal. "The pressure difference between the upper and lower plates is too large, which will affect the gray scale change of the liquid crystal display panel." For the Vcommon voltage on the upper board, whether the Vcommon voltage can return to the vcommon voltage level before the end of the Charge; if it cannot return to the Vcommon voltage level, horizontal crosstalk (cr〇ss_ta|k) will occur. For the lower plate 〇 〇 electrode voltage and § ' is in the holding period, the ITO electrode voltage is coupled by the data line data, such as ιτο electrode voltage is coupled severely, vertical crosstalk will occur (cross-talk). For this reason, the present invention proposes a novel liquid crystal display panel and a driving method thereof, which can effectively reduce the cross-talk in the vertical direction generated by the frame inversion polarity conversion method in the prior art, thereby improving the liquid crystal display. The quality of the face of the panel. SUMMARY OF THE INVENTION The main object of the present invention is to provide a novel liquid crystal display panel and a driving method thereof, which adopt a double gate driving circuit and a polarity changing manner of a frame jnverSi〇n, which can reduce vertical crosstalk in the prior art (cross-talk). )The problem.

According to the above configuration, when the new liquid crystal display panel starts scanning, all the first scanning lines are sequentially scanned from top to bottom, and then all the first scanning lines are sequentially scanned from top to bottom. With the newly designed driving method of the present invention, the present invention can reduce the polarity of the double gate driving circuit by using the dual-gate driving circuit under the framework of the double gate driving circuit. Inversion causes vertical crosstalk® (cross咐k) 'to improve the picture quality of frame invers丨on with a different approach.
