Description

TECHNICAL FIELD

The present invention relates to liquid crystal display technology, and more particularly to an array substrate, a liquid crystal display panel and a liquid crystal display.

BACKGROUND

A liquid crystal display (LCD) is a thin flat display device and a LCD panel is an important part of the liquid crystal display. The LCD panel at least includes an array substrate and a color filter substrate disposed opposite to each other, and a liquid crystal layer disposed between the array substrate and the color filter substrate. A pixel array, data lines and scanning lines crossed with each other are disposed in the array substrate. The data lines provide data signals to the pixel array, and the scanning lines provide scanning signals to sub-pixels. In a conventional array substrate, pixels in a same column are connected to a same data line, and the same data line provides data signals for all the pixels in the column. Pixels in a same row are connected to a same scanning line, and the same scanning line provides scanning signals for all the pixels in the row. In an array substrate, there are many other layout designs of data lines and scanning lines, and one of the layout designs can reduce the number of data lines in half and this layout is called a data line share configuration.
FIG. 1 is a schematic view illustrating a part of an array substrate has the conventional data line share configuration. In the array substrate, there are a pixel array, which includes sub-pixels P11, P12, P13, P22, and P23, data lines D1˜D5, and scanning lines G1˜G6 crossed with the data lines D1˜D5. Two horizontally adjacent sub-pixels in the pixel array share a common data line (for example, the sub-pixels P12 and P13 share the data line D2, and the sub-pixels P22 and P23 share the data line D2). According to this configuration, the number data lines can be reduced in half in comparison to the conventional pixel driving array of LCD. Adjacent sub-pixels in a same row are connected to different scanning lines (for example, the sub-pixels P12 and P13 are connected to scanning lines G1 and G2, respectively), every two sub-pixels, which has one sub-pixel disposed therebetween, are connected to a same scanning line (for example, the sub-pixels P11 and P13 are connected to the scanning line G2), vertically adjacent sub-pixels are connected to different scanning lines (for example, the sub-pixels P12 and P22 are connected to scanning lines G2 and G3, respectively). According to this configuration, the number of scanning lines is doubled in comparison to the conventional pixel driving array.
Since the doubled number of scanning lines reduced the scan time allocated to each scanning line, the charging time of sub-pixels is also reduced. Currently, the LCD is usually driven using a dot inversion manner. That is, adjacent two data lines have opposite signal polarity, a same data line has opposite signal polarity at adjacent rows. As the data lines has a certain impedance, delay distortion will occur during the transmission of data signals, and this causes the difference of pixel charging rate between two adjacent columns of data lines. As shown in wave shape of driving signals of FIG. 2, D (odd) is the wave shape of data lines of odd numbers while D (even) is the wave shape of data lines of even numbers. D (odd) and D (even) have opposite signal polarity. In FIG. 2, the dashed wave shape is the theoretical wave shape, and the solid wave shape is the actual wave shape having delay distortion. Referring to FIG. 1, taking the wave shape D (even) at the data line D2 as an example, when the scanning lines G1˜G4 are switched on sequentially, the data line D2 charges the sub-pixels P12, P13, P22 and P23 in the same sequence. The data line D2 charges two sub-pixels P12, P13 and the two sub-pixels P22, P23 in a same signal polarity cycle, respectively. In a same signal polarity cycle, insufficient charging exists in the sub-pixels P12 and P22 that are firstly charged due to the signal distortion and the sub-pixels P12 and P22 have lower brightness. The sub-pixels P13 and P23 that are finally charged have higher charging rate and have higher brightness. Taking a look at the entire column, a bright-dark line is produced. Similarly, a plurality of spaced bright-dark lines along the vertical direction will be produced in the entire LCD panel, and the display quality is reduced.
Based on the above, it is desired to provide a solution to overcome the defect of bright-dark lines in liquid crystal display panels.

The two scanning lines are only used to drive the same row of sub-pixels (e.g., the two scanning lines at top and bottom of a first row of sub-pixels shown in the figure is the scanning lines G11 and G21, respectively, and the scanning lines G11 and G21 are only used to drive the first row of sub-pixels). Then, the sub-pixel array is divided into row groups 21, 22, 23, 24, 25, 26 and 27. In the present embodiment, each row group includes one row of sub-pixels. That is, the row group 21 includes one row of sub-pixels; the row group 22 includes one row of sub-pixels, and so on.
The sub-pixels and the scanning lines are connected in the following manners.
For sub-pixels in the row groups 21, 27 and in the column groups numbered with even numbers 12, 14, each sub-pixel is connected to a corresponding scanning line disposed on a top of a corresponding row (e.g., sub-pixels P13, P14, in the row group 21 and the column group 12 are both connected to the scanning line G11, sub-pixels P73, P74 in the row group 27 and the column group 12 are both connected to the gate line G17). For sub-pixels in the row groups 21, 27 and in the column groups numbered with odd numbers 11, 13, each sub-pixel is connected to a corresponding scanning line disposed on a bottom of a corresponding row (e.g., sub-pixels P11, P12, in the row group 21 and the column group 11 are both connected to the scanning line G21, sub-pixels P71, P72 in the row group 27 and the column group 11 are both connected to the gate line G27).
For sub-pixels numbered with i and i+1 in each row of the row groups 22 and 26, each sub-pixel is connected to a corresponding scanning line disposed on a top of a corresponding row (e.g., a second sub-pixel P22 and a third sub-pixel P23 in the row group 22 are connected to the scanning line G12, a second sub-pixel P62 and a third sub-pixel P63 in the row group 26 are connected to the scanning line G16). For sub-pixels numbered with j and j+3 in each row of the row groups 22 and 26, each sub-pixel is connected to a corresponding scanning line disposed on a bottom of a corresponding row (e.g., a first sub-pixel P21 and a fourth sub-pixel P24 in the row group 22 are connected to the scanning line G22, a first sub-pixel P62 and a fourth sub-pixel P64 in the row group 26 are connected to the scanning line G26). i=2, 6; j=1, 5.
For sub-pixels in the row groups 23, 25 and in the column groups numbered with odd numbers 11, 13, each sub-pixel is connected to a corresponding scanning line disposed on a top of a corresponding row (e.g., sub-pixels P31, P32, in the row group 23 and the column group 11 are both connected to the scanning line G13, sub-pixels P51, P52 in the row group 25 and the column group 11 are both connected to the gate line 15). For sub-pixels in the row groups 23, 25 and in the column groups numbered with even numbers 12, 14, each sub-pixel is connected to a corresponding scanning line disposed on a bottom of a corresponding row (e.g., sub-pixels P33, P34, in the row group 23 and the column group 12 are both connected to the scanning line G23, sub-pixels P33, P34 n the row group 25 and the column group 12 are both connected to the gate line G25).
For sub-pixels numbered with j and j+3 in each row of the row group 24, each sub-pixel is connected to a corresponding scanning line disposed on a top of a corresponding row (e.g., a first sub-pixel P41 and a fourth sub-pixel P44 in the row group 24 are connected to the scanning line G14). For sub-pixels numbered with i and i+1 in each row of the row group 24, each sub-pixel is connected to a corresponding scanning line disposed on a bottom of a corresponding row (e.g., a second sub-pixel P42 and a third sub-pixel P43 in the row group 24 are connected to the scanning line G24). i=2, 6; j=1, 5.
Each sub-pixel Pxy is connected to the corresponding data line and scanning lines using a switching element. In detail, as shown in FIG. 4, taking the sub-pixel P13 as an example, the switching element in the present embodiment is a thin film transistor (TFT). A gate electrode 10 a of the TFT is electrically connected to a corresponding scanning line G11, a source electrode 10 b of the TFT is electrically connected to a corresponding data line D2, and a drain electrode 10 c of the TFT is electrically connected to the sub-pixel P13.
If a dot inversion driving manner is used, the charging process is described taking the sub-pixels P12, P13 P22, P23, P32, P33, P42, P43, P52, P53, P62, P63, P72, P73 disposed at two sides of the data line D2 as a example. Referring to FIG. 3, when the scanning line G11, G21, . . . G17, and G27 are switched on sequentially, the sub-pixels P12, P13, P22, P32, P33, P42, P52, P53, P62, P72 and P73 are charged by the data line D2, the sub-pixels P23, P43 and P63 are charged by the data line D3. In the sub-pixels of the column Px2, the sub-pixels P12, P42 and P72 are sub-pixels that are sufficiently charged, the sub-pixels P22, P32, P52 and P62 are sub-pixels that are insufficiently charged.

In the figure, the white portions represent sufficiently charged sub-pixels, and the shadow portions represent insufficiently charged sub-pixels. As shown in the figure, in sub-pixels of a same column, sufficiently charged sub-pixels and insufficiently charged sub-pixels are alternately distributed, and in sub-pixels of a same row, there are also alternately distributed sufficiently charged sub-pixels and insufficiently charged sub-pixels. Therefore, a LCD panel including the array substrate has even brightness uniformity, and the defect of vertical bright-dark lines is alleviated.
The array substrate of the present embodiment can be obtained by repeating the partial structure shown in the FIG. 3 in the horizontal and vertical directions.

Embodiment 2

For example, in all the sub-pixels in the 1st row and the 2nd row in the row group 21 a, the two vertically adjacent sub-pixels (e.g., the sub-pixels P11 and P21) have the same connection manner. All the sub-pixels in the 1st row and the 2nd row are connected to the data lines and scanning lines in a manner same to the row group 21 of embodiment 1.
