Description
Technical Field
The invention relates to the technical field of display, in particular to a display driving method of a liquid crystal display panel and the liquid crystal display panel.
Background
The liquid crystal display panel comprises a plurality of sub-pixels which are arranged in an array mode, each sub-pixel is electrically connected with a grid line and a data line, when the grid lines are conducted, data signals on the data lines can be written into the sub-pixels, the transmittance of liquid crystals is controlled, and the display effect is achieved.
In the related art, a Dual Gate Line (Dual Gate Line) array substrate for a liquid crystal display panel is proposed, referring to fig. 1, the array substrate includes a plurality of Gate lines 11, i.e., a first Gate Line G1, a second Gate Line G2, a third Gate Line G3, a fourth Gate Line G4, a fifth Gate Line G5, and a sixth Gate Line G6, a plurality of data lines 12 crossing the Gate lines 11 in an insulated manner, i.e., a first data Line S1, a second data Line S2, and a third data Line S3, sub-pixels in any row correspond to two Gate lines 11 located at both sides and adjacent thereto, and sub-pixels therein are electrically connected to the two Gate lines 11 in turn, taking a first row of sub-pixels as an example, wherein sub-pixels located in odd columns, i.e., a first sub-pixel 10a, a third sub-pixel 10c, and a fifth sub-pixel 10e are electrically connected to a first Gate Line 1, and sub-pixels located in even columns, i.e., a second sub-pixel 10b, a fourth sub-pixel 10d, a third sub-pixel 10c, and a fifth sub-pixel 10e, The sixth subpixel 10f is electrically connected to the second gate line G2; all the column sub-pixels are divided into a plurality of groups, each group includes two columns of adjacent sub-pixels, all the sub-pixels in any group are electrically connected with one data line 12 between two columns of sub-pixels, taking the first data line S1 as an example, the first data line S1 is arranged between the first column of sub-pixels and the second column of sub-pixels, and the first column of sub-pixels and the second column of sub-pixels are electrically connected with the first data line S1. The double-gate line type array substrate reduces the number of the data lines 12 by half, thereby effectively reducing the production cost of the liquid crystal display panel.
However, when the on signal is applied to the gate line, the data signal of the pixel electrode of the sub-pixel adjacent to the gate line is reduced due to the coupling effect, and further, under the condition that the common voltage is not changed, the driving voltage value of the sub-pixel to which the positive polarity data signal is input (i.e., the absolute value of the difference between the data signal and the common voltage) is reduced (so that the brightness thereof is darker), and the driving voltage value of the sub-pixel to which the negative polarity data signal is input is increased (so that the brightness thereof is brighter). Therefore, when the column inversion driving method is adopted (i.e., the polarities of the data signals of each data Line in one frame are the same, and the polarities of the data signals of the adjacent data lines are opposite), bright and dark stripes (i.e., poor V-Line) are generated in the display frame, thereby affecting the viewing experience.
When the dual-grid line type array substrate is used for displaying, each row of sub-pixels is influenced by the two corresponding grid lines, so that the brightness of the sub-pixels at the same position in two adjacent frame pictures is respectively the brightest and the darkest, the brightness difference is large, and the viewing experience is influenced.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, a display unit, a display substrate, a driving method thereof, and a display device provided by the present invention are described in further detail below with reference to the accompanying drawings and the detailed description.
Example 1:
referring to fig. 2a, fig. 2b and fig. 3, the present embodiment provides a display driving method of a liquid crystal display panel, for example, the method is operated in a liquid crystal display panel to drive a display of the liquid crystal display panel, the liquid crystal display panel includes an array substrate, and the array substrate includes:
a plurality of sub-pixels 10 arranged in an array;
a plurality of gate lines 11 extending in a row direction, a plurality of data lines 12 extending in a column direction;
each sub-pixel 10 is electrically connected to one gate line 11 and one data line 12;
any row of sub-pixels 10 corresponds to two grid lines 11 which are positioned at two sides of the sub-pixels and adjacent to the sub-pixels, and the sub-pixels 10 are electrically connected with the two grid lines 11 in turn;
all the column sub-pixels 10 are divided into a plurality of groups, each group is two columns of adjacent sub-pixels 10, and all the sub-pixels 10 in any group are electrically connected with a data line 12 positioned between the two columns of sub-pixels 10;
the display driving method includes:
in any frame, the gate lines 11 are turned on in turn, and data signals are provided to the data lines 12, wherein the polarity of the data signals provided to the same data line 12 is unchanged, and the polarity of the data signals provided to any two adjacent data lines 12 is opposite;
in any two adjacent frames, the two gate lines 11 corresponding to any row of sub-pixels 10 are conducted in the opposite sequence, and the polarity of the data signal provided to any data line 12 is opposite.
Specifically, referring to fig. 2a, 2b and 3, each row of sub-pixels 10 corresponds to two gate lines 11 located on two sides of and adjacent to the sub-pixel 10, that is, all sub-pixels 10 in the row are controlled by two gate lines 11; for example, the first row of sub-pixels 10 corresponds to the first gate line G1 and the second gate line G2, the sub-pixels 10 in the odd columns of the first row of sub-pixels 10 are electrically connected to the first gate line G1, and the sub-pixels 10 in the even columns of the first row of sub-pixels 10 are electrically connected to the second gate line G2. Meanwhile, every two columns of the sub-pixels 10 are divided into one group, and each group of the sub-pixels 10 is controlled by one data line 12 positioned therein; for example, the first column of sub-pixels 10 and the second column of sub-pixels 10 are grouped and are electrically connected to the first data line S1, the third column of sub-pixels 10 and the fourth column of sub-pixels 10 are grouped and are electrically connected to the second data line S2, and the fifth column of sub-pixels 10 and the sixth column of sub-pixels 10 are grouped and are electrically connected to the third data line S3.
In any frame of picture, two gate lines 11 corresponding to a row of sub-pixels 10 are sequentially (or any one of the two gate lines may be on line) turned on, when one gate line 11 is turned on, each data line 12 provides a data signal to the corresponding sub-pixel 10, and the data signals of adjacent data lines 12 are opposite, and the polarity of the data signal of each data signal in one frame of picture is unchanged (i.e. column inversion). The following description will be made by taking the first gate line G1 conducting first and the second gate line G2 conducting later as an example:
when the first gate line G1 is first turned on, the first data line S1, the second data line S2, and the third data line S3 simultaneously output data signals (to the sub-pixels 10 in the odd-numbered columns), the first data line S1 outputs a positive data signal, the second data line S2 outputs a negative data signal, and the third data line S3 outputs a positive data signal. As mentioned above, due to the coupling effect of the gate line 11 conducting signal, the driving voltage values of the first sub-pixel 10a, the second sub-pixel 10b, the fifth sub-pixel 10e, and the sixth sub-pixel 10f in the first row with positive polarity are smaller than the normal value, that is, the display of the first sub-pixel 10a, the second sub-pixel 10b, the fifth sub-pixel 10e, and the sixth sub-pixel 10f is darker than the normal display; the driving voltage values of the third sub-pixel 10c and the fourth sub-pixel 10d in the first row with negative polarity are larger than the normal value, i.e. the display of the third sub-pixel 10c and the fourth sub-pixel 10d is brighter than the normal display.
The second gate line G2 is turned on, and the first data line S1, the second data line S2, and the third data line S3 output data signals (output to the sub-pixels 10 even in the odd-numbered columns) having the same polarity as that of the first gate line G1 when turned on, respectively. Similarly, at this time, the driving voltage values of the first sub-pixel 10a, the second sub-pixel 10b, the third sub-pixel 10c, the fourth sub-pixel 10d, the fifth sub-pixel 10e and the sixth sub-pixel 10f are also affected by the conduction of the gate line G2. However, at this time, the second sub-pixel 10b, the fourth sub-pixel 10d, and the sixth sub-pixel 10f are inputting new data signals, so that the original data signals (the data signals are affected by the first gate line G1) are "erased". Therefore, the driving voltage values of the second sub-pixel 10b, the fourth sub-pixel 10d, and the sixth sub-pixel 10f are affected by the conduction of the primary gate line 11 only for most of the time of one frame, and thus the influence is smaller than the influence of the first sub-pixel 10a, the second sub-pixel 10b, and the third sub-pixel 10c, and it can be considered that the display of the second sub-pixel 10b, the fourth sub-pixel 10d, and the sixth sub-pixel 10f is normal and is flat.
The same problem occurs for the sub-pixels 10 in other rows, and the description thereof is omitted here.
As can be seen from the above description, whatever polarity of the data signal is outputted from the data line 12, the sub-pixel 10 electrically connected to the leading gate line 11 of the two corresponding gate lines 11 will be significantly brighter or darker in any frame. Therefore, the sub-pixels 10 in different columns in the corresponding display image of fig. 1 have periodic brightness differences of dark, flat, bright and flat, thereby forming vertical stripes, see table 1.
Therefore, when the liquid crystal display panel is scanned according to the conventional method (i.e. the gate lines 11 are conducted in the same sequence in different frames, which is called Z-scan), the polarities of the data signals of the same data line 12 in adjacent frames are changed, so that the states of the sub-pixels 10 in each row in the second frame are as shown in table 2. As can be seen from this, in the adjacent frame pictures, periodic luminance differences (dark, bright), (flat ), (bright, dark), (flat ) and the like appear in the same display area, and since the luminance difference is large when some of them are listed in "dark, bright" or "bright, dark" switching luminance differences, the vertical stripes are easily caught by human eyes.
TABLE 1
TABLE 2
In the above solution of this embodiment, in any two adjacent frames, the conducting sequence of the two gate lines 11 corresponding to any row of sub-pixels 10 is opposite, and the polarity of the data signal provided to any data line 12 is opposite, and substantially, the sub-pixel 10 that is bright (or dark) in the previous frame is inevitably flat in the next frame, and will not become dark (or bright), and only the sub-pixel 10 that is flat in the previous frame will be bright (dark) in the next frame. Therefore, when the liquid crystal display panel displays, only such periodic brightness differences (dark, flat), (flat, bright), (bright, flat), (flat, and dark) occur in the same display area in multiple frames of pictures, that is, an excessive frame picture with flat brightness is inserted between bright and dark, so that the brightness change of the same display area in two adjacent pictures is reduced, thereby improving the display effect of the liquid crystal display panel, and tables 3 and 4 respectively show the display conditions of the 6 columns of sub-pixels 10 of the two frames of pictures after the images in fig. 2a and 2 b.
TABLE 3
TABLE 4
Alternatively, in any two adjacent frames, all the gate lines 11 are sequentially turned on in a first order along the column direction in one frame, and sequentially turned on in a second order along the column direction in the other frame, where the first order is opposite to the second order.
That is, in each frame, all the gate lines 11 may be sequentially turned on in the order of the column direction, and the turn-on orders of all the gate lines 11 in different frames are opposite to each other, so as to simplify the driving process. For example, referring to fig. 2a and 2b, all the gate lines 11 in the first frame may be sequentially turned on from top to bottom, and all the gate lines 11 in the second frame may be sequentially turned on from bottom to top, so that the process is repeated.
Optionally, the liquid crystal display panel further includes a plurality of common electrodes (not shown in the figure), each common electrode corresponding to a row of the sub-pixels 10;
in any frame, when a first-conducted grid line 11 of two grid lines 11 corresponding to any row of sub-pixels 10 is conducted, outputting a first common voltage to a common electrode corresponding to the row of sub-pixels 10, and outputting a second common voltage to the common electrode corresponding to the row of sub-pixels 10 in other time;
wherein the first common voltage is less than the second common voltage.
In the above scheme, each common electrode corresponds to one row of sub-pixels 10, so the voltage value output by the common electrode 11 can be changed according to the conduction sequence of the gate line 11, and further, tests show that the first common voltage is smaller than the second common voltage, which is beneficial to reducing the difference between brightness and darkness in the picture.
Optionally, the common electrode is time-division multiplexed as a touch electrode.
Since the common electrode is divided into a plurality of common electrodes, the common electrode can be used as a touch electrode (such as a scan electrode) in the touch stage, so as to realize the touch function of the liquid crystal display panel (i.e. the TDDI panel) without increasing the hardware structure.
Optionally, the sub-pixels 10 are divided into a plurality of different colors, wherein the same color is used for the sub-pixels 10 in the same column.
Alternatively, in order to make the liquid crystal display panel have as many colors as possible, the plurality of different colors include three colors of red (R), green (G), and blue (B). Further, along the row direction, the colors of the sub-pixels 10 in each column may be cyclically distributed in a certain order (e.g., red-green-blue).
The brightness difference caused by the conduction of the gate line 11 is in units of "rows", so when the sub-pixels 10 in the same row have the same color, the above difference is more obvious, and the liquid crystal display panel having the same color of the sub-pixels 10 in the same row is more suitable for adopting the scheme of this embodiment.
Optionally, the liquid crystal display panel displays a pure color picture; in the pure color picture, all the sub-pixels 10 of the same color have the same display luminance.
As mentioned above, the above brightness difference is more obvious in the pure color picture, so it is more suitable for the scheme of this embodiment.
Of course, the application range of the present invention is not limited to the above Z scanning manner, and it is feasible as long as the conducting sequence of the two gate lines corresponding to any row of sub-pixels in any two adjacent frame pictures is opposite; and in any frame, it is feasible that when the first conducting grid line of the two grid lines corresponding to any row of sub-pixels is conducted, the first common voltage is output to the common electrode corresponding to the row of sub-pixels, and the second common voltage which is larger than the first common voltage is output to the common electrode corresponding to the row of sub-pixels in other time.

in any two adjacent frames, the gate line control module controls the conduction sequence of the two gate lines 11 corresponding to any row of sub-pixels 10 to be opposite, and the data line control module provides data signals to any data line 12 with opposite polarities.
In the above solution, the display driving unit controls the sub-pixel 10 that is bright (dark) in the previous frame to be flat in the next frame, and the sub-pixel 10 that is flat in the previous frame to be bright (dark) in the next frame, so when the liquid crystal display panel performs image display, periodic brightness differences (dark, flat), (flat, bright), (bright, flat), (flat, and dark) may occur in the same display area between the displayed frames, that is, a frame of flat transition frame is inserted between bright and dark, so that the brightness change of the same display area in the two adjacent frames is reduced, thereby improving the display effect of the liquid crystal display panel.

wherein the first common voltage is less than the second common voltage.
