However, due to the limitations of the liquid crystal molecules themselves, liquid crystal molecules have a specific response time constant. If the response time is longer than the val), the result is blurred and ^after (afterimage), so that a good image cannot be obtained. * The constant between the ringers is too long. In addition to the method of improving the liquid =, the functional structure of the display panel can also be solved by improving the drive design, which mainly includes - ash 2 = (10) ' for receiving and adjusting gray scale data signals; - timing control for controlling signals Synchronization and display timing; - gate drive ^ ° ° supply scan signal - source driver hall, using ^ two-digit digital data converted to Na Ying ·, gray 15 white liquid crystal panel 108, including a plurality of gate lines 11 〇 ' 一 一 一 一 一 一 112 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 ^ The role played by 1〇〇. The original j I30〇md〇c/g signal data is first compensated by the gray-scale signal conditioner 100 to solve the problem of motion image blur residual image, and the adjusted gray-scale signal is output to the driving circuit of the liquid crystal panel to provide appropriate data. Voltage at the source driver, the correct color brightness of the image. The conventional technique of π gray-scale signal compensation is to accelerate the driving (0 verdri ving) technique as shown in Fig. 2. In the current frame, one pixel is grayscale 〇, and the next frame is the same: when the pixel is grayscale 100, it must be To give a voltage exceeding the gray level, the liquid crystal molecules of the pixel are rotated to the gray level 100 faster, and when the same pixel of the next frame is still grayscale 100, the voltage is restored to the voltage of the gray level 100. _Supply over the effective range of the liquid crystal molecules to increase the dynamic speed of the image. However, the 255-day temple cannot use the technology of accelerated driving. 』Yes and gray-scale signal compensation another ------ Bai Zhiqi feng pre-tilt (pre-tilt) heart technology as shown in Figure 3 § Shovel a frame a pixel is grayscale 〇, the next frame is the same Call, the frame must first be given to a pre-flip dipping voltage to make the LCD flip first. Due to the physical properties of the liquid crystal molecules, the liquid i molecules first flipped _ no money flipping reaction faster, so the molecular rotation speed can be improved to improve the dynamic kneading image product 1 and in a frame a pixel is a high gray level value (such as grayscale 100), and the same pixel grayscale is 〇, and the lower-frame is the same as the -pixel is high grayscale 1〇〇), because the pixel ί liquid in this frame time 1曰兮=(4) to the position of the gray level G. If the person reduces the inversion voltage, the second pixel will be discharged too slowly, causing the same image of the frame to be too bright, which will make the quality worse. . I3〇〇?5l3Ld〇c/g SUMMARY OF THE INVENTION The object of the present invention is to provide a liquid crystal display panel driving method and a driving circuit to improve dynamic picture output quality. The invention provides a driving method for a liquid crystal panel. The method mainly comprises: starting a liquid crystal molecule from a low gray level (such as 〇 to 2 〇 gray scale): ^ ' may result in the inability to reach (10) required brightness in the frame time 2 In this method, the original frame signal is divided into a plurality of sub-frame signals, respectively, for processing. If the current two frames are low gray levels (such as 〇 to % gray or the frame is low gray level (such as 0 to 20 gray scale), the brightness of the front-frame can be discharged to the low gray level (such as 〇 to 2 〇 gray level) in the next frame time, so that the lower-frame liquid crystal flip phase will exceed the frame _, and When the brightness is not displayed, the sub-frames in the figure (4) will be pre-flipped. According to a preferred embodiment of the present invention, the first sub-frame is a two-speed drive. _ action, when the situation is that the brightness of the front-frame reaches the current frame, the time will exceed one frame time, so that the frame time is not reached; the degree 'the first sub-frame of the frame The action that will be driven by the mouth speed can reach the target brightness in time. In the preferred embodiment, the dividing the original frame signal into the _ sub-signal can also be divided into a plurality of sub-frames for adjusting the pre-flip time and the acceleration driving time. The method of the frame separately judges the pre-flip and the acceleration drive, so that the response time of the liquid crystal molecules can be improved too slowly = the motion blur and the afterimage are displayed when the dynamic image is displayed, and the unnecessary pre-i30〇2j3^wfdoc/g is flipped first. The action of the crystal can solve the ambiguity and residual image of the dynamic image. In order to make the above and other objects, features and advantages of the present invention more obvious, the following is a better example of the text, Wei He Lai, for details f embodiment] FIG. 4 is a flow chart of the present invention. First, a frame is input first (the step of step 1 is attached (step 4 is called, and the impurity is divided into the same gray level b frame), and then the frame of the input is judged. The picture with the previous input is f. The gray level to the first - pre-coffee 2 no' does not pre-flip (step 408); if it is, then: step:) step = ^ value time, = value == = two no 'there is no pre-flip (step) action; The second frame is a pre-flip action (step 406). Example 2: cutting, the sub-frame Ai and the sub-frame Bi, respectively, are gamma', and the gray-scale values of the Fl are equal to the sub-picture Box π. Since the graph is divided into two sub-picture sub-frames Ai time plus sub-picture frame, Ai Figure 6 is the implementation of the above flow chart ^: 1 time. The block diagram of this device contains the first - first = Doc/g 602 and lookup table B 604. The lookup table B can receive two input frame data and receive a clock signal (not shown) as the access timing (4). Lookup table B _ first stores a search data set corresponding to all possible two inputs, each set of search data sets describes a sub-frame NewBn corresponding to the desired output when inputting a particular sub-frame Bw, Bn, Bn+1, The possible cases are as follows: The right two sub-frames have several pixels in the sub-frame that are smaller than the Pnmit gray-scale value (this value is set according to: when the liquid crystal molecules are changed from the sub-frame Bn_! to the sub-frame Bn and displayed correctly The time of the brightness of the sub-frame Bn is 'less than or equal to - frame time, 'sub-frame Bn' The value represented is the Piimit gray scale value; from the above definition, it can be seen that the 'different sub-frame Bn' and the sub-picture box will produce different gray scale values. ), the sub-frame Bn box is low gray level (for example, 〇 to % gray level) 'Bn+1 is 咼 gray level (for example, 24〇 to gray level), when the liquid crystal molecules are changed from sub-frame Bn] When the sub-picture frame is centered, the liquid crystal numerator can be changed to the angle represented by the sub-frame group at the angle represented by the sub-frame Bn" in a predetermined pixel (4) Tpix (pfe_detel^_ period), but the liquid crystal molecules are changed from sub-frame to Sub-frames are low-gray to high-level), and the time required for flipping exceeds one-between' sub-frames need to be pre-flipped, and the brightness requirement can be reached within -frame time. The frame New Bn performs a pre-flip action, and the frame NewBn will not be equal to the sub-frame Bn. Figure 2. If the data does not meet the above conditions, it is expected that the sub-frame New Bn is equal to the sub-frame Bn. Next, the operation of the search data table B 604 to input the sub-frames Βηΐ, β, b and the corresponding output sub-New Bn is described. The first frame memory receives the sub-frame Bn+1, and sends the sub-frame Bn to the look-up table b. The second frame is the memory 602; the second frame memory 6〇2 receives the sub-frame & and sends the sub-frame Bn] to the look-up table B; the look-up table B receives the sub-frame Bn!, the team, B n +! 'The sub-analysis with the search data set to output the sub-frame N ew B η. Since the grayscale values of the sub-frames and the frame are the same, it is not limited to use the sub-frames for comparison, and the original frames can also be used for comparison. σ In the above example, if we want to speed up the response time of the liquid crystal molecules, we can also use the sub-frame that is displayed first in the split frame to do the acceleration drive. The flow chart is as shown in Fig. 7. First, the sub-frame displayed first in the frame is obtained (step 700), and whether the difference between the gray level value of the sub-picture (4) and the gray-scale value of the front-sub-frame is greater than the second The preset value (step 702), wherein the preset value 盥, the frame time is related, if not before the second preset value, it means that the frame reaches the δ hull degree when the frame is in the frame, so the acceleration drive is not performed. Tick (4) The second preset value indicates that the frame will reach the redundancy within the frame time ,, and the sub-frame is accelerated to drive (step Sichuan 6). 8 is an overload driving device 8 (9) of the above-described flowchart, the circuit block diagram includes a first frame memory surface, and a second frame memory body can receive frame data of two wheel people, and receive the time frame The pulse signal (not shown) is used as the timing control for access.
