Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of display technology, and more particularly to a driving method of a display panel and a display device using the same. [Prior Art] In the conventional column inversion driving technology, most of the scanning lines in the display panel are sequentially driven in an odd number, and then the scanning lines numbered evenly are sequentially driven, and the display panel is displayed. The upper substrate (ie, the color filter substrate) and the lower substrate (ie, the thin film transistor array substrate) both adopt the same common potential. Figure 1 shows the gate timing and common potential timing used for this drive technology. In FIG. 1, R 〇 W [l], R0W [3], and R 〇 w [5] indicate the gate signals corresponding to the first column of pixels, the third column of pixels, and the fifth column of pixels, respectively. Mark

However, such a driving technique causes a problem that the odd-numbered pixel columns and the even-numbered pixel columns are inconsistent in brightness, and the luminance unevenness (so-called Mura phenomenon) of the entire display panel is also caused. The above questions will be explained in detail below. First, a pixel equivalent circuit of a conventional display panel using column inversion driving technology will be described. (5) That is, green indicates the halogen equivalent circuit. Referring to Fig. 2, the bismuth 2〇6 main body is composed of a membrane transistor 2〇8, a storage capacitor (10) and a halogen capacitor. The gate of the transistor 2〇8 electrically consumes a scan line, and the source/drain of the thin film transistor 208 is electrically connected to a data line 2〇4. Storage 4 201239840 ? r One end of the common electrode electrically coupled to the lower substrate is electrically connected to the common electrode Vc0m-Clc of the upper substrate. The common electric fevcom-Cst and vcom Clc are electrically connected to the same common potential. Further, the thin film transistor 208, the storage capacitor 210 and the halogen capacitor 212 are electrically connected to each other as a so-called halogen electrode. Assuming that all the elements of the traditional display panel are to display the phase-gray scale, then the voltage changes on the -data line and the voltage change of the common electric meQm will be as shown in Figure 3. Fig. 3 is a diagram for explaining the problem that the luminances of the pixel columns of the odd-numbered pixel columns and the even-numbered pixel columns are inconsistent. Referring to FIG. 3, the facet display period of each face is divided into two time segments, which are respectively indicated by the mark I and the mark Π. N is a natural number. In the time zone, the odd-numbered pixel columns are sequentially opened, and in the time segment 11_, the even-numbered pixel columns are sequentially turned on. In addition, the waveform indicated by the indication 302 is represented as a voltage change of the common potential Vc〇m, and the readout indicated by the label $304 is expressed as a voltage change on any of the data lines. The waveform indicated by the indication 306 is represented as an odd number. The voltage on any of the pixel electrodes of the pixel array changes, and the waveform indicated by reference numeral 308 is represented as a voltage change on any of the pixel electrodes of any of the even-numbered pixel columns. The above common potential Vcom has two levels. When the voltage on the data line is greater than the voltage of the common potential Vcom, the pixel loaded into the display data will exhibit a positive polarity; and when the voltage on the data line is less than the voltage of the common potential VC0m, the pixel loaded into the display data will be presented. Negative polarity. Let us now look at the manner in which the voltage is described by waveform 306. In the time segment I of each picture, since only the odd-numbered pixel columns are sequentially turned on, the voltage level on each of the pixel electrodes in these pixel columns is pulled to the voltage on the data line. Level; whenever the time segment η enters the time segment η, since the odd-numbered pixel columns are all closed, each of these pixel columns stores 201239840 t storage valleys per pixel capacitor All of them exhibit a floating state, and at this time, the common potential Vcom is changed to a level, so that the voltage level on each of the pixel electrodes in the pixel columns will change the common potential Vc〇m. However, by waveform 306 and waveform 304, it can be seen that there is a large pressure difference between each of the pixel electrodes of the odd-numbered f-column and the corresponding data line in the time segment (four) of each picture. Thus, the thin film transistor is leaked for a long time. Next, the voltage change mode described by the waveform 308 is seen. In the time segment 昼 of each face, since only the even numbered pixel columns are sequentially turned on, these The electricity on each of the pixel electrodes in the prime column The level will be pulled to the voltage level on the data line; and each time the time segment j enters the time segment ^, the common potential Vcom changes the level so that each of the two elements in the even-numbered pixel column The voltage level on the element electrode fluctuates with the variation of the common potential Vcom. However, since these elementary columns are turned on, the voltage level on each of the pixel electrodes in these elements is immediately pulled to the data. The voltage level on the line. Therefore, there is a large voltage difference between each pixel electrode of the even-numbered pixel column and the corresponding data line at the moment when the common potential Vcom changes level, so these pixels The leakage time of the thin film transistor in the column is very short. From the above description, it is known that the leakage time of the thin film transistor of the odd-numbered pixel array is different from the leakage time of the thin film transistor of the even-numbered pixel array. Therefore, the brightness of the odd-numbered elementary column is inconsistent with the brightness of the even-numbered pixel column. Figure 4 is a diagram for explaining the problem of uneven brightness of the entire display panel. In Figure 4, the standard The same as the one shown in Fig. 3 is shown as the same object. Unlike Fig. 3, the waveform 302 in Fig. 4 shows the actual voltage change of the common potential Vcom. From this figure, the common potential Vcom is changed. After quasi-quasitivity, the voltage difference between the common potential Vcom and the voltage on the data line will gradually decrease. This means that 6 201239840 in the time zone π, the surface of the opened material will be smaller than the display voltage of the person in the open prime column. The frame is displayed during the display period of the screen that is loaded from the display of the data displayed by the number of people in the a phase, and the displayed data is displayed on the same page. The transfer is less than the voltage of the display data loaded by the prime column of the closed number. Thus, the degree of the odd number is decremented or incremented from the top, and _ produces ^; SUMMARY OF THE INVENTION The object of the present invention is to provide a method for resolving the traditional form of the invention.

HI The present invention solves the above-mentioned problems by providing a plurality of common electrodes in a lower substrate of a display panel and electrically connecting the same scanning lines to the same-common electrode. No common electrode is provided in the upper substrate of the display panel. Then, a plurality of common potentials having different timings are supplied to the common electrode', and before the pixel is turned on, the level of the common potential corresponding to the pixel to be turned on is switched first. Since the voltage of the pixel electrode corresponding to the same scanning line changes with the change of the same common potential, the voltage difference between the pixel electrode corresponding to each scanning line and the common potential corresponding to each scanning line remains the same, thereby solving the problem. The problem is that the brightness of the odd-numbered column is inconsistent with the brightness of the even-numbered pixel column. Even if the common potential occurs in the situation shown in FIG. 4, since the scanning voltage 201239840 = the voltage difference of the common potential corresponding to the pixel electrode of f and the respective scanning lines is still accompanied by a 2, the entire display panel is also solved. The above and other objects, features and advantages of the present invention will be apparent from the accompanying drawings. [Embodiment] A display (four) board made of a dry fabric.

As for the Vpixel[1], Vpixd[3] and VPixd[479] respectively, the voltage of any of the halogen electrodes of the third column of the first column of pixels is the voltage of the fourth electrode and the fourth hundred and seventy The voltage of any of the halogen electrodes of the nine columns of halogens is indicated by Vpixel[2], Vpixel[4] and Vpixel[480], respectively, indicating the voltage of any of the halogen electrodes of the second column of halogens, and the fourth column The voltage of any of the pixel electrodes and the voltage of any of the four hundred and eighty columns of pixels. As shown in FIG. 7, the voltage of the pixel electrode of the same pixel column changes with the change of the same common potential, so that the voltage difference of the common potential corresponding to the pixel electrode corresponding to each scanning line and each known line is different. Consistently, the problem of the brightness of the odd-numbered column of the odd-numbered column and the brightness of the elementary column of the even number is not solved. Even if the common potential occurs in the case shown in FIG. 4, since the difference between the pixel electrodes corresponding to the respective scanning lines and the common potential corresponding to the respective scanning lines remains the same, the brightness unevenness of the entire display panel is also solved. The problem. 13 201239840 Second Embodiment: This embodiment mainly explains that the driving method described in FIG. 6 can also be applied to different pixel architectures, which is illustrated in FIG. 8. Figure 8 is a schematic diagram of the structure of a display panel. In FIG. 8, the symbol 802 is represented as a halogen, and the marks 811 to 816 are represented as data lines, and the labels R〇w[ml], R〇w[m], and Row[m+l] are represented as scan lines 'where m is The natural number, and the designation Vcom_Cst[m] is represented as a common electrode corresponding to the known line Row[m]. As can be seen from Fig. 6, the pixels of the display panel are electrically coupled to the scan lines in a zigzag manner, so that any two adjacent pixels on the same scan line are located in different columns. Implementing the driving method shown in Fig. 6 under such a pixel structure can achieve the effect of dot inversion on the display panel. In this way, it is possible to use the effect of averaging the visuals to further improve the problem that the brightness of the odd-numbered elementary columns is inconsistent with the brightness of the even-numbered elementary columns. Third Embodiment: This embodiment mainly explains that the scan lines of the display panel described in the first embodiment can also be divided into more groups for driving, which is explained in FIG. Fig. 9 is an explanatory view showing a driving method of a display panel in accordance with another embodiment of the present invention.

As shown in FIG. 9, in this driving method, the scan lines numbered odd are sequentially divided into a plurality of groups, and the scan lines numbered evenly are sequentially divided into a plurality of groups, wherein each group includes There are 2 scan lines. Of course, each group also includes: so includes N scan lines' as long as the natural number is expected. Then, each time - the square of the group is ordered (4) in the scan line in the group, and in the group of the temporally adjacent group, the scan line numbers in the group are all odd, and the other - group internal line The common potential corresponding to the sweep and the drive domain is odd: the common potential corresponding to the sweeping of the == is presented in the other ^ i + "" face, when the drive number is odd In the case of a line, the common potential corresponding to the pixel being turned on is a data line that is turned on in the slabs of the scan lines so as to correspond to the low level, and the data lines presented by the (four) correction systems are made to correspond In these 丄: ·,., member is not in the panel 'the polarity of the positive and negative polarity is opposite: Tian, dan, has positive polarity. Similarly, when at the N+1蚩, the scan line that drives the library with the odd number is provided with the positive low-level data signal, and the data drives the pixels of these scan lines. | Right ^Do not block the order green, so that the brightness of 15 201239840 is 0:2: The brightness of ::= is inconsistent with the brightness of the even numbered element column. & prime column = tube In this example, the scan lines in each group are driven sequentially. However, the designer can also change the movement of each group as an example, and can drive the third scan line first. And then drive the first-filament line. Next, 4 drives the fourth scan = the teachings of the respective embodiments can be summarized as shown in Fig. 10 of the driving method of the present invention. Figure 10 is a flow diagram of a method in accordance with the present invention. The display panel has a plurality of book strips, a plurality of scan lines and a plurality of common electrodes, and the above-mentioned halogen line: the upper two-ray 2 data line and the scan line are electrically coupled to the above-mentioned halogen, and the above-mentioned common The power_ is set at _;; Γ and the in-position have $one quasi-second level (as in step S1002, the signal to the sweep 4 is more: the timing is different) If there is a display panel, then the internal control circuit of the display device is driven by the driving method of the present invention; the teaching of the example can also summarize the two basic operational behaviors of the display. Please refer to FIG. 11 for a description of a display device. The display device includes a timing controller 1102, a data driver 1104, a scan driver U〇6, a common potential supply circuit 1108, and a display panel 1110. The display panel 1110 has a plurality of pixels (as indicated by the numeral 1112), a plurality of data lines (as indicated by the numeral 1114), a sigma line (as indicated by the numeral 1116), and a plurality of common electrodes (such as the label 1118). No. The above alizarins are arranged in a matrix, the data line and the scan line are electrically coupled to the pixel, and the common electrode is disposed in a substrate (not shown) of the display panel 110. The data driver 1104 is electrically coupled to the material The scan driver 11〇6 is electrically coupled to the scan line. The timing controller 1102 is electrically coupled to the data driver 11〇4 and the scan driver=1=6, and is used during a display period. Control scan driver η% provides a plurality of timing different gate signals to the above scan lines for turning on the above-mentioned memory. The timing controller 1102 is also used to control the data driver "〇4 to transparently corresponding to the data line The display data is loaded into the opened pixel. As for the common potential supply circuit i1G8', it is used to provide a plurality of common electric circuits with different timings to the upper electrode, wherein each of the common potentials has a first level and a second level. Before, the Ron potential supply circuit Cong first switched to open the drawing path (10). It is the same as the electric switch. It is worth mentioning that the 'common potential supply of electricity, when to switch; the same: 2: Quasi-to-scan However, the timing controller 1102 may also be divided into a plurality of groups according to the following: the number: the odd-numbered scan lines are sequentially divided into a plurality of groups, and each group includes eight fields. Line, and Ν is a natural number. Then the timing 栌 栌 1102 control the scan driver w stupid control 1102 can scan the line, which in the time If group way to drive the group, neighbors Scans in one of the groups 17 201239840 line numbers are all odd 'and the other - the scan line numbers in the group are even. And when the drive 1106 drives the odd number of scan lines, it is turned on. The potential of the halogen element assumes the first level 'When the scan driver 1106 drives the scan line numbered evenly, the potential level corresponding to the turned-on pixel is the second level. According to the above description, the fourth method of solving the pre-production method is to provide a plurality of common electrodes in the display panel = lower substrate, and the same electro-visual image of the same scanning line is connected to the common electrode. No common electrode is provided in the upper substrate of the display panel. Then, a plurality of common potentials having different timings are supplied to the common electrode, and before the pixel is turned on, the level of the common potential of the t corresponding to the pixel to be turned on is switched. Since the voltage of the pixel electrode corresponding to the same-scanning line changes with the change of the common potential, the voltage difference between the electrode corresponding to each scanning line and the common potential of each scanning line is kept constant, thus The problem of the parity of the odd-numbered array of pixels and the parity of the even-numbered array of pixels is determined. Even if the common potential occurs in the case shown in FIG. 4, the mutual retention of the pixel electrodes corresponding to the respective scanning lines and the respective scanning lines also solves the luminance unevenness of the entire display panel. The above has been disclosed in the preferred embodiments, but it is not intended to be used in the present invention.
