Description of the Invention: [Technical Field] [0001] The present invention relates to a display, and more particularly to a liquid crystal display and a driving method thereof. [Prior Art] [0002] Liquid crystal displays are widely used in mobile phones, personal digital assistants, notebook computers, and televisions due to their light weight, low power consumption, and low radiation. In a general thin film transistor liquid crystal display, the principle of image display is: controlling the twist angle of liquid crystal molecules by changing the voltage applied to each pixel region to change the electric field on both sides of the liquid crystal molecules corresponding to the pixel region. And then control the luminous flux of the pixel region to achieve. However, the liquid crystal molecules have such a characteristic that if the electric field direction applied to the two sides of the liquid crystal layer remains unchanged for a long time, the physical characteristics of the liquid crystal molecules are destroyed, that is, the corresponding rotation of the liquid crystal molecules can no longer be performed according to the change of the electric field. Therefore, it is necessary to change the direction of the electric field applied to the two sides of the liquid crystal layer at regular intervals so that the liquid crystal molecules are alternately deflected in opposite directions to prevent the physical properties from being destroyed. At present, the reverse driving method of the liquid crystal display includes a frame inversion driving method, a row inversion driving method, a column inversion driving method, and a dot inversion driving method (Dot Inversion) method. . Among them, the display effect of driving the liquid crystal display by the dot inversion driving method is better [0003], however, the liquid crystal display is driven by the dot inversion driving method, since the polarity of the voltage applied to each pixel is different from that of the adjacent pixels. The voltage applied to each data line by the data driver changes from one polarity to the other. 099118690 Form No. A0101 Page 4 / Total 36 Page 0992033108-0 201145247 Sex (eg, from positive polarity to negative polarity) is required A certain charging time 'causes the charging time of each element is insufficient' and thus affects the display effect of the liquid crystal display. In addition, since the power consumption of the data driver is related to the frequency of voltage change applied to each data line, the greater the frequency of change of the voltage, the more power it consumes, so 'the dot inversion driving method is used.

Then, the scan driver 26 outputs a complex scan voltage to the virtual scan line G·. The polarity and magnitude of the second 2K+1 voltage outputted to each data line D correspond to the pre-displayed j + Ι frame picture, and the first pixel group 234 is connected to the data line D· The data voltage pre-loaded by the prime 228 is the same polarity and size to pre-charge the complex data line D_. Compared with the prior art, when the liquid crystal display 200 of the second embodiment of the present invention displays each frame, its data driver 26 outputs the data voltage of each column of pixels 228 of the first pixel group 234. Thereafter, before outputting the data voltages of the columns 228 of the second pixel group 236, the first voltage is further outputted to each data line, and is output to the first of each data line D_. The polarity of the voltage corresponds to the data voltage preloaded by the pixel 228 connected to the data line D· in the second pixel group 236 Μ 099118690 Form No. 1010101 Page 17 / Total 36 Page 0992033108-0 201145247 Sex The same, thus, the complex data line D, to achieve pre-charging. Therefore, the resource driver 26 outputs the data voltage of the first column of pixels 228 corresponding to the second pixel group 236 without polarity inversion, so that the first column of the second pixel group 236 is 228. Also charged more. In addition, especially when the magnitude of the first voltage is the same as the data voltage preloaded by the pixel 228 connected to the data line D_ in the second pixel group 236, the data driver 26 outputs the same. The data voltage of the first pixel 228 of the second pixel group 236 does not rise slowly or slowly decreases on the complex data line D·, so the first column of the second pixel group 236 The pixel 228 is more fully charged. [0033] Further, since the liquid crystal display 200 displays the j-th frame before displaying the j-th frame, the data driver 24 further outputs the second voltage to each data line D_, and outputs to each The polarity and magnitude of the second voltage of a data line D· Μ , corresponds to the pixel 228 connected to the data line I)· in the first pixel group 234 corresponding to the pre-display j+1 frame frame. The preloaded data voltage has the same polarity and size, so that the complex data line D_ is precharged again. Therefore, when the liquid crystal display 200 displays the frame of the j+1 frame, the data driver 26 outputs the data voltage corresponding to the first column of pixels 228 of the first pixel group 234, and does not need polarity inversion, and is not slow. The process of rising or slowing down changes, so that the first column of pixels 228 of the first pixel group 234 is also fully charged. 099118690 Form No. A0101 Page 18/36 Page 0992033108-0 201145247 [0035] In summary, since the pixels 228 of the liquid crystal display 200 are all fully charged, the liquid crystal display 200 has a more display effect. it is good. The present invention is not limited to the above embodiment. After the liquid crystal display device 100 rotates the data voltage corresponding to the first pixel group 134, the data driver 14 further outputs a plurality of first voltages to the plurality of data lines DM'. The first voltage outputted to each of the data lines dm corresponds to the same polarity as the data voltage preloaded by the pixels 228 connected to the data line DM in the second pixel group 136. The data driver 14 outputs a data voltage corresponding to the second pixel group 136 after a certain time delay, so that the complex data line is pre-charged. Preferably, the magnitude of the first voltage corresponds to the same magnitude of the data voltage preloaded by the pixel 128 connected to the data line Ι>Μ in the second pixel group 136. In addition, the data squeaker 14 preferably delays the data voltage of the second pixel group 136 after delaying the time required for one column of pixels 128 to load the data voltage. [0036] 资料 After the liquid crystal display 1 〇〇 displays the i-th frame, before displaying the 1 + 1 φ 贞 picture, the data driver 14 further outputs a plurality of second voltages to the complex data line Du. Wherein, the polarity of the second voltage outputted to each data line Dm is preloaded corresponding to the pixel 128 connected to the data line DM in the first pixel group 134 corresponding to the pre-display of the i+1 frame The data voltages are the same polarity. The data driver 14 delays outputting the data voltage of the first pixel group 134 corresponding to the i + 1 frame picture, so that the complex data line DM is precharged. Preferably, the size of the second voltage corresponds to the pre-displayed i + Ι frame picture, and the data voltage preloaded by the pixel 128 connected to the data line Dm in the first pixel group 134 is the same size. Thus, the pixel I28 of the liquid crystal display 100 is fully charged, so that the liquid crystal display 099118690 form number A0101 page 19/36 page 0992033108-0 201145247 100 has a better display effect. [0037] The liquid crystal display 100, 200 may also output a data voltage of each column of pixels 128, 228 of the second pixel group 136, 236, and then output the first pixel group 134, 234. The data voltage of each column of pixels 128, 228. [0038] According to whether the polarities of the data voltages loaded by the pixels 128 and 228 are the same, the plural pixels 228 connected to any one of the data lines Du and D_ except the data line D14D· may be divided into The first set of cells 130, 230 and the second set of cells 132, 232.
