## Background
FIELD OF THE INVENTION
The present invention relates to the field of a liquid crystal display (LCD), and especially to an LCD panel.
BACKGROUND OF THE INVENTION
With a growing popularity of the LCD, the LCD is demanded for better functions.
Referring to FIG. 1, FIG. 1 is a schematic drawing illustrating pixel structures of an LCD panel in the prior art. The LCD panel includes m data lines D′′1 ̃D′′m and n scan lines G′′1 ̃G′′n. The data lines intersect the scan lines, and two adjacent data lines intersect two adjacent scan lines to define a pixel unit (not labeled). A thin film transistor (TFT) and a liquid crystal capacitor (not shown) are disposed on each pixel unit.
Data signals that are transmitted on the data lines D′′1 ̃D′′m can be divided into data signals of positive polarity and data signals of negative polarity reference to a common voltage Vcom which is 0 v. The data signals of positive polarity means that the voltages of data signals are higher than the common voltage Vcom, and the data signals of negative polarity means that the voltages of data signals are lower than the common voltage Vcom. When a data signal of positive polarity and a data signal of negative polarity both have the same gray scale value, theoretically, they have the same display effects.
Liquid crystal molecules have followed common character: when both sides of a liquid crystal layer are applied to electric field and if the direction of the electric field is kept constant for a long time, the characteristics of the liquid crystal molecules are destroyed. That is, the liquid crystal molecules fail to rotate in response to changes of the electric field for forming various gray scales. Therefore, the direction of the electric field has to change every a period of time for reversing the liquid crystal molecules so as to prevent the characteristics of the liquid crystal molecules from being destroyed. There are a variety of driving methods to realize the reversal of the liquid crystal molecules in the LCD field, such as dot inversion, 1+2 dot inversion, column inversion, and row inversion.
When the driving method of the 1+2 dot inversion is employed in the above-mentioned LCD panel, in the case of the pixel units in each row, the direction of the electric field of the liquid crystal capacitance in (4k−3)th and (4k)th columns of the pixel units is opposite to the direction of the electric field of the liquid crystal capacitance in (4k−2)th and (4k−1)th columns of the pixel units. Thus, the polarity of the gray scale voltages of the data lines D′′4k−3 and D′′4k is opposite to the polarity of the gray scale voltages of the data lines D′′4k−2 and D′′4k−1, where K is an arbitrary natural number. In addition, the direction of the electric field of the liquid crystal capacitance in odd rows of the pixel units and even rows of the pixel units are opposite. Thus, the voltages of the data lines D′′4k−3 and D′′4k as well as the data lines D′′4k−2 and D′′4k−1 have to continuously switch their polarity in a frame time T as shown in FIG. 2. However, the frequent polarity switching must increase power consumption of the LCD panel, resulting in waste of resources.

Referring to FIG. 5, FIG. 5 is a schematic drawing illustrating waveforms of the data lines of the LCD panel driven by using the 1+2 dot inversion in FIG. 3. The polarity of the grayscale voltage of each of the data lines remains unchanged for a frame time T, and the two adjacent data lines are provided the grayscale voltages with two opposite polarities. In the embodiment, the grayscale voltages of the first data line D4i−3, the third data line D4i−1, and the fifth data line D4i+1 of odd number columns have a positive polarity (i. e., the voltages are higher than a common voltage). The grayscale voltages of the second data line D4i−2, the fourth data line D4i of even number columns have a negative polarity (i. e. the voltages are lower than a common voltage).
Referring to FIG. 4 and FIG. 5, a driving method of the pixel unit set 31 of the LCD panel is described as follows.
First, the first scan line Gj provides a scanning signal, and the thin film transistors of the first pixel unit 311 and the third pixel unit 313 are turned on; meanwhile, the first data line D4i−3 provides a grayscale voltage with a positive polarity to the first pixel unit 311, and the fourth data line D4i provides a grayscale voltage with a negative polarity to the third pixel unit 313.
Then the second scan line Gj+1 provides a scanning signal, and the thin film transistors of the second pixel unit 312, the fourth pixel unit 314, the sixth pixel unit 316 and the eighth pixel unit 318 are turned on simultaneously. Meanwhile, the second data line D4i−2 provides a grayscale voltage with a negative polarity to the second pixel unit 312. The third data line D4i−1 provides a grayscale voltage with a positive polarity to the sixth pixel unit 316. The fourth data line D4i provides a grayscale voltage with a negative polarity to the eighth pixel unit 318.

As mentioned above, the grayscale voltages with the positive polarity of the first data line D4i−3, the third data line D4i−1, and the fifth data line D4i+1 are provided for the first pixel unit 311 and the fourth pixel unit 314 at two sides of the first row of the four pixel units as well as for the sixth pixel unit 316 and the seventh pixel unit 317 at a middle of second row of the four pixel units. the grayscale voltages with the negative polarity of the second data line D4i−2 and the fourth data line D4i are provided for the second pixel unit 312 and the third pixel unit 313 at a middle of the first row of the four pixel units as well as for the fifth pixel unit 315 and the eighth pixel unit 318 at two sides of second row of the four pixel units. A driving method of other pixel unit sets 31 is identical to the driving method of the pixel unit set 31. Therefore, the grayscale voltages with the positive polarity of the first data line D4i−3, the third data line D4i−1, and the fifth data line D4i+1 located at the odd columns are written into the first pixel unit 311 and the fourth pixel unit 314 at the two sides of the first row of each pixel unit set 31, as well as written into the sixth pixel unit 316 and the seventh pixel unit 317 at the middle of the second of each pixel unit set 31. The pixel units, which are written into the grayscale voltage with the negative polarity of the second data line D4i−2 and the fourth data line D4i located at the even columns, are alternate with the pixel units, which are written into the grayscale voltage with the positive polarity of the first data line D4i−3, the third data line D4i−1, and the fifth data line D4i+1 at the odd columns, thereby achieving the 1+2 dot inversion as shown in FIG. 3.
In comparison with the prior art, the LCD panel of the present invention can realize the 1+2 dot inversion without continuously switching the polarities of the grayscale voltages on the data lines. Thus, the power consumption of the LCD panel of the present invention is greatly reduced.
Referring to FIG. 6, the pixel unit set of the LCD panel in the second embodiment are substantially identical to the pixel unit set in the first embodiment of the present invention, the difference therebetween is that the configurations of the pixel units at the first row and the second row are exchanged. Specifically, the pixel unit set 31′′ includes a ninth pixel unit 311′′, a tenth pixel unit 312′′, a eleventh pixel unit 313′′, and a twelfth pixel unit 314′′ arranged in a first row as well as a thirteenth pixel unit 315′′, a fourteenth pixel unit 316′′, a fifteenth pixel unit 317′′, and an sixteenth pixel unit 318′′ arranged in a second row.

In the four adjacent pixel units of the first row, the gates of the thin film transistors of the ninth pixel unit 311′′ and the eleventh pixel unit 313′′ are coupled to the second scan line Gj+1, and the gates of the thin film transistors of the tenth pixel unit 312′′ and the twelfth pixel unit 314′′ are coupled to the first scan line Gj. In the second row of the four pixel units, the gates of the thin film transistors of the thirteenth pixel unit 315′′ and the fifteenth pixel unit 317′′ are coupled to the second scan line Gj+1, and the gates of the thin film transistors of the fourteenth pixel unit 316′′ and the sixteenth pixel unit 318′′ are coupled to the third scan line Gj+2.
The LCD panel of the present invention is not limited to the embodiments. For example, the coupling relation between the gates of the thin film transistors of the pixel units and the scan lines can be changed, while it can be conformed that the gates of the thin film transistors of the pixel units in an identical data line are coupled to different scan lines.
While the preferred embodiments of the present invention have been illustrated and described in detail, various modifications and alterations can be made by persons skilled in this art.
