The body writes the data of the halogen' and also passes through the parasitic electricity; the feedthrough voltage is generated on the second. In the second period τ2, when the ::曰曰 voltage level V4 is shouted to the reference voltage V3, the compensation is applied to the liquid crystal capacitor, and the bias voltage of the liquid crystal capacitor is pulled to form the positive electrode as shown in FIG. 3B. When the gate signal of the gate and the line is in the shape of the gate, the gate signal will be in the period of the first period, the reference voltage, the voltage level V, and the second period T2, the gate signal will be voltage. Bit ^ V1 falls to V2 ' and returns to reference voltage 3 after the second (four) Τ 2 . In the first-T1 towel's voltage scale νι, the main crystal is opened to correspond to the f-crystal in the image, and the feed-through voltage is generated on the liquid aa capacitor via the parasitic capacitance. In the second period T2, when the gate is returned from the voltage level V2 to the reference voltage V3, it is coupled to the liquid crystal capacitor through the compensation I valley, and further reduces the bias of the liquid crystal capacitor to form a negative polarity drive. Next, taking the halogen 212 as an example, the driving method of the display panel 2A will be described in conjunction with the wheel-out waveforms of the gate lines Gf^ and GM. Please refer to FIG. 2 to FIG. 4 at the same time. FIG. 4 is a driving waveform diagram according to a second embodiment of the present invention. In the present embodiment, 'the voltage change on the pixel electrode of the halogen 212 is represented by the halogen voltage PW', and the gate signals Gmj, Qm are output signals by the gate signals SGm-! and SGM. The driving polarity of the halogen 212 is determined by the voltage across the pixel voltage PW and the common voltage VC〇M. Since the driving method of the display panel 200 is described by taking the driving method of the dot inversion as an example, the driving polarity of the display panel 200 is different in different kneading planes. First, when the halogen 212 is driven by the negative polarity, the gate signal is a negative drive waveform 'and the gate signal SGm is a positive drive wave: 1:1 U rises to the voltage level VlBf, and the bismuth prime 21 213 turns on. The even-numbered elements 212, 214 will generate a voltage due to ^ cst, so the pixel voltage pw will rise first = the gate signal SGM is enabled to turn on the odd number of the pixel column, and the 223 time 'the pixel voltage pw will At the same time, because the gate signal "generates the ____ signal_% rise, the feedthrough 2 is decreased, when the gate signal is committed (6) from the voltage level: When the reference power plant is requested, the pixel voltage PW will enter again = 2 Finally, when the gate signal SGm returns to the reference/negative voltage, it will rise slightly because of the feedthrough voltage. If the region 41 keeps the mountain and enters the lower jaw, the driving polarity of the element will change. ♦ 219 is the positive drive waveform, and the gate signal % is the negative drive wave. The second will rise first because of the turn-off of the gate signal (6). The gate signal SG drops and falls.

As shown in FIG. 5A, the total falling voltage is equal to (dvl + dV2_dV3), and as shown in FIG. 5B, the total rising voltage is equal to (_dV4 + dV5_dV6). In conjunction with the above circuit parameter values and the voltage change of the gate signal, the following r can be summarized, the equation: dV\ + dV2 - dV3 = {VG * CGD + VEl * CST} / [CST + CLC + CGD] ~ dV4 + dV5 - dV6 = {- * CGD + VE2 * C5r}/[OT + CLC + CGD] — where 'CST, CLC, CGD represent the compensation capacitor, liquid crystal capacitor, and gate (source) parasitic capacitance of the transistor, respectively. Adjusted by the design (layout) of the pixel structure; VE1 represents the difference between the voltage level reference voltage V3, VE; 2 represents the difference between the reference voltage vs and the voltage bit $V4' can be passed through the gate The waveform of the polar signal is adjusted. Therefore, by changing the component polarity and the gate signal in the whole pixel structure, the driving polarity of the pixel can be changed, thereby reducing the power consumption of the hybrid driver. In the dot-inversion driving mode, the even-numbered elements (e.g., 212, 214) in the pixel column P S1 have the same driving polarity, and the driving mode is as described above, and the driving mode is no longer described. * The driving polarity of odd-numbered pixels in psl, such as 211 and 213), and the even-numbered elements 212 and 214, only need to adjust the output waveform of the closed-loop line, 'in this technology. 13 200903428 nm 1 _乜B1JL \V 23519twf.doc / p has a general knowledge in the field of technology, through the disclosure of the present invention, the driving waveform of the remaining gate lines should be easily inferred, and will not be described here. The third embodiment of the present invention and the above-mentioned embodiment are summarized as follows: 'The driving method of the display panel is applied to the display panel 2'. The driving method includes the following steps. First, the step S610 sequentially scans the display panel 2 The gate line; then, in step S620, when the pixel is positively driven, the output of the first line is made to be a positive drive waveform '(four) two gates, _output is a negative drive-waveform; in step S63G Tow, when the element is driven by the negative polarity, the first action is to make the first drive line of the second gate line negative drive' /, and the middle gate line represents the last gate line. The singularity of the current scan will be passed through the second sluice. The above-described driving is referred to the description of the above-mentioned first and second embodiments, and the person having ordinary knowledge is inferred from the present invention, and will not be described here. In the above, the present invention proposes a new aspect: the driving technique can be directly applied to the dot inversion display: the power consumption of the quadrupole circuit. Reducing the drive is not intended to be used in the spirit of the present invention and is not to be taken as a part of the scope of the present invention; the subject matter is: 14 200903428 1 W 23519twf.doc/p.
