Description:
FIELD OF THE INVENTION 
       [0001]    Embodiments of the invention relate to a liquid crystal display (LCD) and a LCD panel. 
       BACKGROUND 
       [0002]    A configuration of conventional LCDs generally comprises a display panel having a sub-pixel array disposed thereon, a source driver for driving source electrodes of the sub-pixels and having data lines, a gate driver for driving gate electrodes of the sub-pixels and having scan lines, a timing controller and a backlight unit. 
         [0003]    In conventional technologies, a Dual-Gate technology and a Triple-Gate technology respectively increase the data lines by more than one or two times. Though both technologies may reduce the cost, the charge time of the pixels is decreased as well, making it difficult to meet the requirement on charge time for high-resolution and stereoscopic displays. 
         [0004]    For the purpose of meeting the requirement on charge time for high-resolution stereoscopic (3D) displays, the Chinese patent publication CN 101494020 titled “A Display Device” discloses a solution of halving the scan lines in the gate driver while doubling the data lines in the source driver, which may double the charge time of the pixels. However, with the development of 3D displays having a refresh rate of 240 Hz and higher resolutions, it requires an ever shorter time for charging hold capacitors when writing pixels. Therefore, it still can not meet the high quality requirement of 3D high resolution display with 240 Hz refresh rate by halving the charge time. 
         [0005]    Moreover, in terms of inversion manners, dot inversion may provides the best picture quality with the least flicker. However, for a configuration using the dot inversion as illustrated in  FIGS. 2 and 3 , with each frame, a polarity of a drive signal on each data line has to be inverted once after the scan time of each scan line, thereby consuming much power and easily increasing the temperature of the source driver on the LCD panel.

         [0038]    In the following, the embodiment of the invention will be described in detail with reference to the drawings and detailed embodiments. 
         [0039]      FIG. 1  schematically illustrates a configuration of a LCD in accordance with an embodiment of the invention.

         [0040]    In the embodiment, taking a LCD with a resolution of m*n as an example, there are m row by n column pixels on the LCD panel  101  of such a LCD. The pixels may employ three primary colors of Red Green Blue (RGB), four primary colors of Red Green Blue White (RGBW), four primary colors of Red Green Blue Yellow (RGBW) or five primary colors of Red Green Blue Yellow White (RGBYW). Accordingly, there is a n row by Mm column sub-pixel matrix on the LCD panel, wherein M is equal to the number of primary colors, that is, 3, 4 or 5. As an example, each pixel has M sub-pixels of different primary colors, and sub-pixels of each pixel are arranged along a row. 
         [0041]    There are a plurality of data lines, a plurality of scan lines and a plurality of pixels arranged into a matrix on the LCD panel  101 . There are totally n/N scan lines and MNm data lines, or there are totally n/N scan lines and MNm+1 data lines; the source driver  102  is adapted for driving source electrodes of the sub-pixels, the gate driver  103  is adapted for driving gate electrodes of the sub-pixels. 
         [0042]    In the embodiment, pixels in the (Ni+1)th, (Ni+2)th . . . and (Ni+N)th rows are all connected to the (i+1)th scan line G(i+1), i is a non-negative integer less than or equal to (n/N)−1, N is an odd number greater than or equal to 3, and n is greater than or equal to N; the data lines are connected accordingly such that drive signals on the same data line are of the same polarity for the same frame, drive signals on two adjacent data lines are of the opposite polarities for the same frame, and drive signals on the same data line are of the opposite polarities for different frames. 
         [0043]    In the case of having n/N scan lines and MNm data lines, sub-pixels in the jth column are respectively connected to the (Nj−N+1)th, (Nj−N+2)th . . . (Nj−1)th, (Nj)th data lines S(Nj−N+1), S(Nj−N+2) . . . S(Nj−1), S(Nj), according to the (Ni+1)th, (Ni+2)th . . . (Ni+N)th rows of the sub-pixel matrix where the sub-pixels are located; where j is an integer greater than or equal to 1 and less than or equal to Mm, i is a non-negative integer less than or equal to (n/N)−1. In the case of having n/N scan lines and MNm+I data lines, sub-pixels in the jth column are respectively connected to the (Nj−N+1)th, (Nj−N+2)th . . . (Nj−1)th, (Nj)th, (Nj−N+2)th, (Nj−N+3)th . . . (Nj−1)th, (Nj)th, (Nj+1)th data lines S(Nj−N+1), S(Nj−N+2) . . . S(Nj−1), S(Nj), S(Nj−N+2), S(Nj−N+3) . . . S(Nj−1), S(Nj), S(Nj+1) according to the (2Ni+l)th, (2Ni+2)th, (2Ni+3)th . . . (2Ni+2N−1)th, (2Ni+2N)th rows of the sub-pixel matrix where the sub-pixels are located; where j is an integer greater than or equal to 1 and less than or equal to Mm, i is a non-negative integer less than or equal to (n/N)−1. 
         [0044]    Furthermore, for the whole picture, in the case of having n/N scan lines and MNm data lines, an inversion manner for the sub-pixels in the first row is dot inversion, and an inversion manner for the rest of the sub-pixels is (N−2)+2 dot inversion. Herein (N−2)+2 dot inversion refers to the following way of inversion: of sub-pixels in each row other than the first and the nth row, N rows of the sub-pixels are considered as a unit, among which sub-pixels in the first N−2 rows are dot inverted, while those in the remaining two rows are 2dot inverted. For the whole image, in the case of having n/N scan lines and MNm+1 data lines, all the sub-pixels are dot inverted. 
         [0045]    When the G(i+1) line of the gate driver is turned on, data on the (Ni+1)th, (Ni+2)th . . . (Ni+N)th rows is written into the corresponding sub-pixels via the corresponding data lines, where N is an odd number greater than or equal to 3, i is a non-integer less than or equal to (n/N−1). 
       Embodiment 1 
       [0046]    As illustrated in  FIG. 4 , in the embodiment, N is equal to 3 and M is also 3, RGB sub-pixels of the same pixel are disposed horizontally. There are n/3 scan lines and 9m data lines, that is, the scan lines for pixels in the (3i+1)th, (3i+2)th, (3i+3)th row are connected together and then connected to the (i+1)th line G(i+1) of the gate driver, where i is a non-negative integer less than or equal to (n/3)−1; sub-pixels in the jth column are respectively connected to the (3j−2)th, (3j−1)th, (3j)th data lines S(3j−3), S(3j−1), S(3j), according to the different (3i+1)th, (3i+2)th, (3i+3)th rows of the sub-pixel matrix where the sub-pixels are located; where j is an integer greater than or equal to 1 and less than or equal to 3m. 
         [0047]    A frame is realized in the following way: 
         [0048]    when G1 is turned on, data on the 1st, 2ed, 3rd rows is written to corresponding pixels via the corresponding data lines. For example, data R 1,1  corresponding to the red sub-pixel in the first row and first column is output at S1, data R 2,1  corresponding to the red sub-pixel in the second row and first column is output at S2, data R 3,1  corresponding to the red sub-pixel at the third row and first column is output at S3, . . . , data B 1,m  corresponding to the blue sub-pixel at the first row and mth column is output at S(9m−2), data B 2,m  corresponding to the blue sub-pixel at the second row and mth column is output at S(9m−1), data B 3,m  corresponding to the blue sub-pixel at the third row and mth column is output at S(9m); 
         [0049]    . . . . 
         [0050]    when G2 is turned on, data on the 4th, 5th, 6th rows is written to corresponding pixels via the corresponding data lines. For example, data R 4,1  corresponding to the red sub-pixel in the fourth row and first column is output at S1, data R 5,1  corresponding to the red sub-pixel in the fifth row and first column is output at S2, data R 6,1  corresponding to the red sub-pixel at the sixth row and first column is output at S3, . . . , data B 4,m  corresponding to the blue sub-pixel at the fourth row and mth column is output at S(9m−2), data B 5,m  corresponding to the blue sub-pixel at the fifth row and mth column is output at S(9m−1), data B 6,m  corresponding to the blue sub-pixel at the sixth row and mth column is output at S(9m); 
         [0051]    when G(n/3−1) is turned on, data on the (n−5)th, (n−4)th, (n−3)th rows is written to corresponding pixels via the corresponding data lines. For example, data R n-5,1  corresponding to the red sub-pixel in the (n−5)th row and first column is output at S1, data R n-4,1  corresponding to the red sub-pixel in the (n−4)th row and first column is output at S2, data R n-3,1  corresponding to the red sub-pixel at the (n−3)th row and first column is output at S3, . . . , data B n-5,m  corresponding to the blue sub-pixel at the (n−5)th row and mth column is output at S(9m−2), data B n-4,m  corresponding to the blue sub-pixel at the (n−4)th row and mth column is output at S(9m−1), data B n-4,m  corresponding to the blue sub-pixel at the (n−3)th row and mth column is output at S(9m); 
         [0052]    when G(n/3) is turned on, data on the (n−2)th, (n−1)th, nth rows is written to corresponding pixels via the corresponding data lines. For example, data corresponding to the red sub-pixel in the (n−2)th row and first column is output at S1, data R n-2,1  corresponding to the red sub-pixel in the (n−1)th row and first column is output at S2, data R n,1  corresponding to the red sub-pixel at the nth row and first column is output at S3, . . . , data B n-2,m  corresponding to the blue sub-pixel at the (n−2)th row and mth column is output at S(9m−2), data corresponding to the blue sub-pixel at the (n−1)th row and mth column is output at S(9m−1), data B n,m  corresponding to the blue sub-pixel at the nth row and mth column is output at S(9m). 
         [0053]    In the embodiment,  FIGS. 5 and 6  are diagrams schematically illustrating polarity inversion between two adjacent frames in accordance with the embodiment of the invention. As illustrated in  FIG. 5  (the Yth frame) and  FIG. 6  (the (Y+1)th frame), when seen from the side of the display panel, the inversion manner for the pixels is 1+2 dot inversion, that is, K rows of pixels are 2 dot inverted, and the pixels in the remaining rows are dot inverted, where K is an integer grater than 1 and less than n, and the remainder of (K−1)/3 is 2 or 0. In terms of the whole picture, of each row other than the first and the nth row and starting from the second row, one row is dot inverted, the following two adjacent rows are two dot inverted, and so on. When seen from the source driver side, for the Yth frame, drive signals on the same data line have the same polarity; for the next frame the (Y+1)th frame, drive signals on that data line have a polarity opposite to that of the driver signals for the previous frame the Yth frame, and drive signals on two adjacent data lines are of opposite polarities when displaying the Yth frame. For example, the first and fourth drive signals on the first data line S1 of  FIG. 5  are both positive. In the next frame, the first and fourth drive signals on the first data line S1 of  FIG. 6  are both negative. The first data line S1 and the second data line S2 in both  FIG. 5  and  FIG. 6  are always of opposite polarities. Therefore, in comparison with the conventional art in which the polarity of the drive signals on each data line has to be inverted once after the scan time of each scan line within one frame, the above technical solution may guarantee the picture quality while reducing the power consumption and the system temperature. 
         [0054]    In the embodiment,  FIG. 7  is a diagram schematically illustrating polarity inversion on source lines S(6j+1), S(6j+2), S(6j+3), S(6j+4), S(6j+5), S(6j+6), S(6j+7) (here j is an integer larger than or equal to 0) of the source driver between different frames, where the high/low level indicates the polarities output on the data lines instead of the specific data output on the data lines. 
       Embodiment 2 
       [0055]    As illustrated in  FIG. 8 , in the embodiment, N is equal to 3 and M is also 3, RGB sub-pixels of the same pixel are disposed horizontally. There are n/3 scan lines and 9m+1 data lines, that is, the scan lines for pixels in the (3i+1)th, (3i+2)th, (3i+3)th row are connected together and then connected to the (i+1)th line G(i+1) of the gate driver, where i is a non-negative integer less than or equal to (n/3)−1; sub-pixels in the jth column are respectively connected to the (3j−2)th, (3j−1)th, (3j)th, (3j−1)th, (3j)th, (3j+1)th data lines S(3j−2), S(3j−1), S(3j), S(3j−1), S(3j), S(3j−1), S(3j+1), according to the different (6i+1)th, (6i+2)th, (6i+3)th, (6i+4)th, (6i+5)th, (6i+6)th rows of the sub-pixel matrix where the sub-pixels are located; where j is an integer greater than or equal to 1 and less than or equal to 3m. 
         [0056]    A frame is realized in the following way: 
         [0057]    when G1 is turned on, data on the 1st, 2ed, 3rd rows is written to corresponding pixels via the corresponding data lines. For example, data R 1,1  corresponding to the red sub-pixel in the first row and first column is output at S1, data R 2,1  corresponding to the red sub-pixel in the second row and first column is output at S2, data R 3,1  corresponding to the red sub-pixel at the third row and first column is output at S3, . . . , data B 1,m  corresponding to the blue sub-pixel at the first row and mth column is output at S(9m−2), data B 2,m  corresponding to the blue sub-pixel at the second row and mth column is output at S(9m−1), data B 3,m  corresponding to the blue sub-pixel at the third row and mth column is output at S(9m); 
         [0058]    when G2 is turned on, data on the 4th, 5th, 6th rows is written to corresponding pixels via the corresponding data lines. For example, data R 4,1  corresponding to the red sub-pixel in the fourth row and first column is output at S2, data R 5,1  corresponding to the red sub-pixel in the fifth row and first column is output at S3, data R 6,1  corresponding to the red sub-pixel at the sixth row and first column is output at S4, . . . , data B 4,m  corresponding to the blue sub-pixel at the fourth row and mth column is output at S(9m−1), data B 5,m  corresponding to the blue sub-pixel at the fifth row and mth column is output at S(9m), data B 6,m  corresponding to the blue sub-pixel at the sixth row and mth column is output at S(9m+1);

         [0060]    when G(n/3−1) is turned on, data on the (n−5)th, (n−4)th, (n−3)th rows is written to corresponding pixels via the corresponding data lines. For example, data R n-5,1  corresponding to the red sub-pixel in the (n−5)th row and first column is output at S1, data R n-4,1  corresponding to the red sub-pixel in the (n−4)th row and first column is output at S2, data R n-3,1  corresponding to the red sub-pixel at the (n−3)th row and first column is output at S3, . . . , data B n-5,m  corresponding to the blue sub-pixel at the (n−5)th row and mth column is output at S(9m−2), data B n-4,m  corresponding to the blue sub-pixel at the (n−4)th row and mth column is output at S(9m−1), data B n-3,m  corresponding to the blue sub-pixel at the (n−3)th row and mth column is output at S(9m); 
         [0061]    when G(n/3) is turned on, data on the (n−2)th, (n−1)th, nth rows is written to corresponding pixels via the corresponding data lines. For example, data R n-2,1  corresponding to the red sub-pixel in the (n−2)th row and first column is output at S2, data R n-1,1  corresponding to the red sub-pixel in the (n−1)th row and first column is output at S3, data R n,1  corresponding to the red sub-pixel at the nth row and first column is output at S4, . . . , data B n-2,m  corresponding to the blue sub-pixel at the (n−2)th row and mth column is output at S(9m−1), data B n-1,m  corresponding to the blue sub-pixel at the (n−1)th row and mth column is output at S(9m), data B n,m  corresponding to the blue sub-pixel at the nth row and mth column is output at S(9m+1). 
         [0062]    In the embodiment, as illustrated in the Yth frame and the (Y+1)th frame ( FIG. 9 ), when seen from the side of the display panel, the inversion manner for the pixels is dot inversion. When seen from the gate driver side, for the Yth frame, drive signals on the same data line have the same polarity; for the next frame the (Y+1)th frame, drive signals on that data line have a polarity opposite to that of the driver signals for the previous frame the Yth frame, and drive signals on two adjacent data lines are of opposite polarities when displaying the Yth frame. For example, the first and seventh drive signals (the seventh not shown in the figure) on the first data line S1 of  FIG. 8  are both positive. In the next frame, the first and seventh drive signals (the seventh not shown in the figure) on the first data line S1 of  FIG. 9  are both negative. The first data line S1 and the second data line S2 in both  FIG. 8  and  FIG. 9  are always of opposite polarities. Therefore, in comparison with the conventional art in which the polarity of the drive signals on each data line has to be inverted once after the scan time of each scan line within one frame, the above technical solution may guarantee the picture quality while reducing the power consumption and the system temperature.

         [0070]    when G(n/3) is turned on, data on the (n−2)th, (n−1)th, nth rows is written to corresponding pixels via the corresponding data lines.

For example, data R n-2,1  corresponding to the red sub-pixel in the (n−2)th row and first column is output at S2, data R n-1,1  corresponding to the red sub-pixel in the (n−1)th row and first column is output at S3, data R n,1  corresponding to the red sub-pixel at the nth row and first column is output at S4, . . . , data W n-2,m  corresponding to the white sub-pixel at the (n−2)th row and mth column is output at S(15m−1), data W n-1,m  corresponding to the white sub-pixel at the (n−1)th row and mth column is output at S(15m), data W n,m  corresponding to the blue sub-pixel at the nth row and mth column is output at S(15m+1). 
         [0098]    In the embodiment, as illustrated in the Yth frame ( FIG. 16 ) and the (Y+1)th frame ( FIG. 17 ), when seen from the side of the display panel, the inversion manner for the pixels is dot inversion. When seen from the gate driver side, for the Yth frame, drive signals on the same data line have the same polarity; for the next frame the (Y+1)th frame, drive signals on that data line have a polarity opposite to that of the driver signals for the previous frame the Yth frame, and drive signals on two adjacent data lines are of opposite polarities when displaying the Yth frame. For example, the first and seventh drive signals (the seventh not shown in the figure) on the first data line S1 of  FIG. 16  are both positive. In the next frame, the first and seventh drive signals (the seventh not shown in the figure) on the first data line S1 of  FIG. 17  are both negative. The first data line S1 and the second data line S2 in both  FIG. 16  and  FIG. 17  are always of opposite polarities. Therefore, in comparison with the conventional art in which the polarity of the drive signals on each data line has to be inverted once after the scan time of each scan line within one frame, the above technical solution may guarantee the picture quality while reducing the power consumption and the system temperature. 
         [0099]      FIG. 7  is a diagram schematically illustrating polarity inversion on data lines S(6j+1), S(6j+2), S(6j+3), S(6j+4), S(6j+5), S(6j+6), S(6j+7) (here j is an integer larger than or equal to 0) of the source driver between different frames, where the high/low level indicates the polarities output on the data lines instead of the specific data output on the data lines. 
         [0100]    What are described above is related to the illustrative embodiments of the disclosure only and not limitative to the scope of the disclosure. As N increases, the number of needed scan lines of the gate driver is 1/N, the charge time for each pixel is N times the original charge time, while the needed data lines is multiplied by N. The choosing of N may be determined in consideration of various factors such as cost, process, and revenue and so on. For example, N may also be an odd number such as 5 and 7. Moreover, N may be selected as multiple values for the same display device, according to the value of n, such as, n=8, a combination of N1−3 and N2=5. The above description is only directed to the preferable case of N=3, and n being an integer multiple of N. however, the invention is not limited to the case of N=3 and n being an integer multiple of N.
