The present application claims priority to Chinese Patent Application No. 202110878022.8, titled “Driving Method of Array Substrate, Array Substrate, And Display Panel” and filed on Jul. 30, 2021, which is hereby incorporated for reference in its entirety for all purposes.
The present application relates to the technical field of an array substrate, and in particular to a driving method of an array substrate and an array substrate.
A driving principle of the array substrate in the related art is generally the polarity inversion drive, that is, a position relationship of the liquid crystal molecules is changed dependent on a change of the voltage, the polarity inversion drive is to apply a voltage signal, whose positive polarity and negative polarity are changed, to liquid crystal molecules to achieve an alternative current drive of the liquid crystal molecules. The polarity inversion drive includes a row inversion drive, a column inversion drive, a frame inversion drive and a point inversion drive, and so on.
The present application is proposed based on the polarity inversion. When a row of pixel units are driven by two row scan lines, since the drive time of the array substrate keeps unchanged, and the row scan lines scan row by row, thus the scan drive time of pixel units of each row is reduced by half. That is, the charging time of each pixel unit is reduced by half. The polarity drive of sub-pixel signal in the same data drive signal line is switched to the reverse polarity. Because of the load effect caused by the parasitic capacitance effect generated by the data drive line and other electrodes, when the polarity drive of the data drive signal line is switched to reverse polarity, the load effect makes the signal of the data drive signal line not reach the required reverse polarity voltage immediately, thus there is a voltage response time.

A control method of the array substrate of the technical solution of the present application is implemented based on the array substrate. The array substrate includes a plurality of sub-pixels, a plurality of data drive signal lines, a plurality of first row scan drive signal lines and a plurality of second row scan drive signal lines. The plurality of sub-pixels are arranged in an array and divided into a plurality of pixel groups according to two adjacent columns of sub-pixels as a group. Each of a plurality of data drive signal lines is provided between two columns of sub-pixels of each pixel group and electrically connected to each sub-pixel of each pixel group. Each row of sub-pixels is divided into the first pixel group and the second pixel group. Each pixel group includes a first sub-pixel and a second sub-pixel provided in turn. In a same row, a first sub-pixel of each pixel group is connected to the first row scan drive signal line and a second sub-pixel of each pixel group is connected to the second row scan drive signal line.

In the first time period, the first polarity data drive signal is output to drive the first sub-pixel of each pixel group to make the first sub-pixel of each pixel group to be a sub-pixel of a first polarity.

With the above solution, the sub-pixels of the first pixel group and the second pixel group of each row connected to the data drive signal lines are driven in different time periods, so that only the first sub-pixel of each pixel group is charged and lighted by the first polarity and/or the second sub-pixel of each pixel group is charged and lighted by the second polarity. Since the sub-pixels of each pixel group are arranged alternately, and the first sub-pixel of the current pixel group is in the same column as the first sub-pixel of the corresponding pixel group of other rows, and the second sub-pixel of the current pixel group is in the same column as the second sub-pixel of the corresponding pixel group of other rows, so that the polarities of each column of sub-pixels are the same and sub-pixels of each column of sub-pixels are evenly spaced or all lighted. Thus the pattern are uniformly displayed and the sufficient charging time is ensured to completely charge. One brighter row of sub-pixels and one darker row of sub-pixels are avoided. The light and dark stripes are not easily happened on the display panel.

If there are descriptions involving “first”, “second” and so on in the embodiment of the present application, the descriptions of “first”, “second” and so on are only for descriptive purposes, and cannot be understood as indicating or implying its relative importance or implicitly indicating the number of indicated technical features.

The present application proposes a driving method of an array substrate to solve a technical problem that light and dark stripes are easily produced on display panels.
In one embodiment, the driving method of the array substrate of the present application is realized based on an array substrate. As shown in
Referring to
S1, data drive signal lines (VDm, VDm+1, VDm+2 . . . VDm+z) are controlled to output a first polarity data drive signal in a first time period and output a second polarity data drive signal in a second time period alternately.
The first time period and the second time period form one period. The data drive signal line outputs the first polarity data drive signal and the second polarity data drive signal alternately in this period.
S2, referring to the schematic diagram on a left side of
Each of all data drive signal lines (VDm, VDm+1, VDm+2 . . . VDm+z) outputs the first polarity data drive signal. Referring to
S3, referring to the schematic diagram on the right side of
Each of the data drive signal lines (VDm, VDm+1, VDm+2 . . . VDm+z) outputs the second polarity data drive signal, and each of the second row scan drive signal lines (VGn+1, VGn+3, VGn+5 . . . VGn+2z+1) outputs the row scan signal to the second sub-pixel of each pixel group connected thereto, to charge the corresponding pixel group and make a polarity of the second sub-pixel of each pixel group to be the second polarity, thereby the first sub-pixel and the second sub-pixel of each pixel group in the array substrate are driven and lighted. Since the first sub-pixel of each pixel group lighted in a previous time period is the first polarity and is discharged, it gradually changes from bright to dark. The overall array substrate thus becomes darker gradually. When brighter, one brighter row of the pixels or one darker row of the pixels won't happen. After the sub-pixel of the first polarity becomes darker, since the pixels of the array substrate are arranged in such way that the sub-pixels of the first polarity and the sub-pixels of the second polarity are arranged alternately along rows where they are located, as shown in
According to the above solution, the data drive signal lines (VDm, VDm+1, VDm+2 . . . , VDm+z) are connected to the first sub-pixel and the second sub-pixel of each pixel group to drive the first sub-pixel in the first time period and to drive the second sub-pixel in the second time period, so that only the first sub-pixel of each pixel group is charged and lighted by the first polarity and/or the second sub-pixel of each pixel group is charged and lighted by the second polarity. Since the first sub-pixel and the second sub-pixel of each pixel group are arranged alternately and the first sub-pixel of each pixel group is in the same column as the first sub-pixel of corresponding pixel groups of other rows. The second sub-pixel of each pixel group is in the same column as the second sub-pixel of corresponding pixel groups of other rows, thus polarities of sub-pixels of each column are the same and the sub-pixels are evenly spaced or all are lighted to make the displayed pattern uniform and have sufficient charging time for completely charge. One brighter row of sub-pixels and one darker row are avoided, the bright and dark stripes are not easily happened on the display panel.
It should be noted that since an interval from the first time period to the second time period is basically less than the perception time of the user's eyes, i.e., the transient effect of the human eye. The brightness change is difficultly perceived by the user. The problem that the bright and dark stripes occur on the display panel is solved, and the user's use and the brightness adjustment function are not affected.
In one embodiment, the first polarity is that a voltage of the first polarity data drive signal is greater than that of a common electrode. The second polarity is that a voltage of the second polarity data drive signal is less than that of the common electrode.
The first polarity of the first polarity data drive signal and the second polarity of the second polarity data drive signal do not refer to a positive voltage or a negative voltage, but to voltages compared to the voltage of the common electrode of the array substrate, i.e., the voltage of the first polarity data drive signal greater than that of the common electrode corresponds to the first polarity and the voltage of the second polarity data drive signal less than that of the common electrode corresponds to the second polarity.
In another embodiment, the second polarity is that the voltage of the first polarity data drive signal is greater than that of the common electrode, and the first polarity is that the voltage of the second polarity data drive signal is less than that of the common electrode.
In one embodiment, a time span of the first time period is equal to that of the second time period.
A time span of the first time period equal to that of the second time period is ensured, which can ensured the display balance of the whole display panel. And one bright row of sub-pixels and one darker row of sub-pixels won't happen. The brightness deviation of the display panel at all the time spans can be reduced.
In one embodiment, the outputting the first polarity data drive signal to drive the first sub-pixel of each pixel group includes:
crossing the row scan drive signal lines (VGn, VGn+1, VGn+2, VGn+3, VGn+4, VGn+5, . . . , VGn+z) along an extension direction of the data drive signal lines to drive the first sub-pixel of each row connected to the first row scan drive signal line in turn with a first polarity data drive signal.
The first sub-pixels of pixel groups of rows are driven with the first polarity data drive signal in turn along the extension direction of the data drive signal line crossing the row scan drive signal lines (VGn, VGn+1, VGn+2, VGn+3, VGn+4, VGn+5 . . . VGn+z), the first sub-pixels of pixel groups of columns is thus charged and lighted row by row. It is effectively avoided that there is a sub-pixel not lighted, and the stability of uniform display is improved.
In one embodiment, the operation of outputting the second polarity data drive signal to drive the second sub-pixel of each pixel group includes:
driving the second sub-pixel of rows, connected to the second row scan drive signal line, in turn with the second polarity data drive signal along the extension direction of the data drive signal lines (VDm, VDm+1, VDm+2 . . . VDm+z).
The second sub-pixel of the pixel groups connected to the current data drive signal line is driven in turn with a second polarity data drive signal along the extension direction of the data drive signal lines (VDm, VDm+1, VDm+2 . . . VDm+z) crossing the row scan drive signal lines (VGn, VGn+1, VGn+2, VGn+3, VGn+4, VGn+5 . . . ), so that the second sub-pixels of the rows are charged and lighted row by row. It is effectively avoided that there is a sub-pixel not lighted, and the stability of uniform display is improved.
To achieve the above purpose, the present application also proposes a driving method of the array substrate. The driving method of the array substrate is achieved based on the array substrate shown in
As shown in
S4, the data drive signal line is controlled to output the first polarity data drive signal in the first time period and the second polarity data drive signal in the second time period alternately.
The first time period and the second time period form a completed period, and the data drive signal line outputs alternately the first polar data drive signal and the second polar data drive signal during the completed period.
S5, in the first time period, referring to the schematic diagram of the array substrate on the left side of
The data drive signal lines (VDm, VDm+2 . . . VDm+2z) connected to the first pixel group outputs the first polarity data drive signal. Each of the first row scan drive signal lines (VGn, VGn+2, VGn+4 . . . VGn+2z) outputs the row scan signal to the first sub-pixel of the first pixel group of each row connected thereto to charge the corresponding pixel groups to make the first sub-pixel of the first pixel group of each row to be a sub-pixel of the first polarity. The data drive signal lines (VDm+1, VDm+3 . . . VDm+2z+1) connected to the second pixel group output the second polarity data drive signal to drive the first sub-pixel of the second pixel group of each row. Each of the first row scan drive signal lines (VGn, VGn+2, VGn+4 . . . VGn+2z) outputs the row scan signal to the first sub-pixel of the second pixel groups of each row connected thereto to charge the corresponding pixel groups to make the first sub-pixels of the second pixel groups of each row to be a sub-pixel of the second polarity. The sub-pixels of the array substrate are driven and lighted by the above process. Since the pixels of the array substrate are arranged in such way that the sub-pixels of the first polarity and the sub-pixels of the second polarity of each row alternately along rows where they are located, and the first sub-pixel group of each row is in the same column as the first sub-pixel groups of other rows, and the second sub-pixel group of each row is in the same column as the second sub-pixel groups of other rows, so that the lighted sub-pixels are arranged alternately in columns, and the array substrate on a whole seems to be lighted unevenly, thus one brighter row of sub-pixels and one darker row of sub-pixels are avoided.
S6, in the second time period, referring to the schematic diagram on the right side of
The data drive signal lines (VDm, VDm+1, VDm+2 . . . VDm+z) connected to the first pixel group output the second polarity data drive signal. Each of the second row scan drive signal lines (VGn+1, VGn+3, VGn+5 . . . VGn+2z+1) outputs the row scan signal to the second sub-pixel of the first pixel group of each row connected thereto to charge the corresponding pixel group to make the second sub-pixel of the first pixel group of each row to be the sub-pixel of the second polarity, and the data drive signal lines (VDm+1, VDm+3 . . . VDm+2z+1) connected to the second pixel group output the first polarity data drive signal to drive the second sub-pixel of the second pixel group of each row, and each of the second row scan drive signal lines (VGn+1, VGn+3, VGn+5 . . . VGn+2z+1) outputs the row scan signal to the second sub-pixel of the second pixel group of each row connected thereto to charge the corresponding pixel group to make the second sub-pixel of the second pixel group of each row to be sub-pixel of the second polarity. Since the first sub-pixel of the first pixel group and the first sub-pixel of the second pixel group of each row lighted in the previous time period are the sub-pixel of the first polarity and are discharged, they gradually become darker from bright, so that the overall brightness of the display panel is gradually darker from bright, and when brighter, one brighter row of sub-pixels and one darker row of sub-pixels won't happen. After the sub-pixel of the first polarity becomes dark, since the pixels of the array substrate are arranged in such way that the sub-pixel of the first polarity and the sub-pixel of the second polarity are arranged alternatively along rows where they are located. The first sub-pixels of the first pixel groups of each row is in the same column as the first sub-pixels of the first pixel groups of other rows, the second sub-pixels of the first pixel groups of each row is in the same column as the second sub-pixels of the first pixel groups of other rows, the first sub-pixels of the second pixel groups of each row is in the same column as the first sub-pixels of the second pixel groups of other rows, and the first sub-pixels of the second pixel groups of each row is in the same column as the first sub-pixel of the second pixel group of other rows. The second sub-pixels of the second pixel groups of each row is in the same column as the second sub-pixels of the second pixel group of other rows, so that the lighted sub-pixels are arranged alternately in columns, and the array substrate on a whole seems to be lighted unevenly, thus one brighter row of sub-pixels and one darker row of sub-pixels are avoided.
With the above solution, sub-pixels of the first pixel group and the second pixel group of each row connected to the data drive signal lines (VDm, VDm+1, VDm+2 . . . VDm+z) are driven in different time periods, so that only the first sub-pixel of the first pixel group is charged and lighted by the first polarity and the first sub-pixel of the second pixel group is charged and lighted by the second polarity, and/or the second sub-pixel of the first pixel group is charged and lighted by the second polarity and the second sub-pixel of the second pixel group is charged and lighted by the first polarity. Since the first pixel group and the second pixel group of each row are arranged alternately, and the first sub-pixel of the first pixel group of each row is in the same column as the first sub-pixels of the first pixel groups of the other rows, the second sub-pixel of the first pixel group of each row is in the same column as the second sub-pixels of the first pixel groups of the other rows, and the first sub-pixel of the second pixel group of each row is in the same column as the second sub-pixel of the second pixel group of each row is in the same column as the second sub-pixel of the second pixel group of other rows, so that the polarities of each column of sub-pixels are the same and sub-pixels of each column of sub-pixels are evenly spaced or all lighted. Thus the pattern are uniformly displayed and the sufficient charging time is ensured to completely charge. One brighter row of sub-pixels and one darker row of sub-pixels are avoided. The light and dark stripes are not easily happened on the display panel.
In one embodiment, it should be noted that since an interval from the first time period to the second time period is basically less than the perception time of the user's eyes, i.e., the transient effect of the human eye. The brightness change is difficultly perceived by the user. A problem is solved that the bright and dark stripes happen on the display panel, and the user's use and the brightness adjustment function are not affected.
In one embodiment, the first polarity is that a voltage of the first polarity data drive signal is greater than that of a common electrode. The second polarity is that a voltage of the second polarity data drive signal is less than a voltage of the common electrode.
The first polarity of the first polarity data drive signal and the second polarity of the second polarity data drive signal do not refer to a positive voltage or a negative voltage, but to voltages compared to the voltage of the common electrode of the array substrate, i.e., that the voltage of the first polarity data drive signal is greater than that of the common electrode is of the first polarity and that the voltage of the second polarity data drive signal less than that of the common electrode is of the second polarity.
In another embodiment, the second polarity is that the voltage of the first polarity data drive signal is greater than that of the common electrode, and the first polarity is that the voltage of the second polarity data drive signal is less than that of the common electrode.
In one embodiment, a time span of the first time period is equal to a time span of the second time period.
Ensuring that the time spans of the first time period and the second time period are equal, the display balance of the display panel on the whole can be ensured. And one row bright of sub-pixels and one darker row of sub-pixels won't happen. The brightness deviation of the display panel at all the time spans can be reduced.
In one embodiment, the outputting a first polarity data drive signal to drive the first sub-pixel of each pixel group includes:
crossing the row scan drive signal lines (VGn, VGn+1, VGn+2, VGn+3, VGn+4, VGn+5, . . . , VGn+z) along an extension direction of the data drive signal lines to drive the first sub-pixel of each row connected to the first row scan drive signal line in turn with a first polarity data drive signal.
The first sub-pixel of the sub-pixel group of each row is driven with the first polarity data drive signal in turn along the extension direction of the data drive signal line crossing the row scan drive signal line (VGn, VGn+1, VGn+2, VGn+3, VGn+4, VGn+5 . . . VGn+z), the first sub-pixel of the first pixel group of each row is thus charged and lighted row by row. The first sub-pixel of second pixel group connected to the first row scan drive signal line is driven with the second polarity data drive signal in turn along the extension direction of the data drive signal line crossing the row scan drive signal line (VGn, VGn+1, VGn+2, VGn+3, VGn+4, VGn+5 . . . VGn+z), the first sub-pixel of second pixel group of each column is thus charged and lighted row by row. It is effectively avoided that there is not lighted sub-pixel, and the stability of uniform display is improved.
In one embodiment, the operation of outputting a second polarity data drive signal to drive a second sub-pixel of each pixel group includes: the second sub-pixel of each row connected to the second row scan drive signal line is driven in turn with the second polarity data drive signal along the extension direction of the data drive signal lines (VDm, VDm+1, VDm+2 . . . VDm+z).
The second sub-pixel of each pixel group connected to the current data drive signal line is driven in turn with a second polarity data drive signal along the extension direction of the data drive signal line (VDm, VDm+1, VDm+2 . . . VDm+z) crossing the row scan drive signal lines (VGn, VGn+1, VGn+2, VGn+3, VGn+4, VGn+5 . . . ) so that the second sub-pixel of each row is charged and lighted row by row. It is effectively avoided that there is not lighted sub-pixel, and the stability of uniform display is improved.
In one embodiment, the operation of the first data drive signal line outputs a second polarity data drive signal to the second row scan drive signal line to drive the second sub-pixel of the first pixel group of each row, and the second data drive signal line outputs a first polarity data drive signal to the second row scan drive signal line to drive the second sub-pixel of the second pixel group of each row includes:
the second sub-pixel of the first pixel group connected to the second row scan drive signal line is driven in turn with the second polar data drive signal along the extension direction of the data drive signal line (VDm, VDm+1, VDm+2 . . . VDm+z);
the second sub-pixel of the second pixel group connected to the second row scan drive signal line is driven in turn with the first polarity data drive signal along the extension direction of the data drive signal lines (VDm, VDm+1, VDm+2 . . . VDm+z).
The second sub-pixel of the first pixel group of two column of sub-pixels connected to the second row scan drive signal line is driven in turn with the second polarity data drive signal along the extension direction of the data drive signal line (VDm, VDm+1, VDm+2 . . . VDm+z) crossing the row scan drive signal line (VGn, VGn+1, VGn+2, VGn+3, VGn+4, VGn+5 . . . VGn+z), so that the second sub-pixel of the first pixel group of each row of sub-pixels is charged and lighted row by row. The second sub-pixel of the second pixel group connected to the second row scan drive signal line is driven in turn with the first polarity data drive signal along the extension direction of the data drive signal line (VDm, VDm+1, VDm+2 . . . VDm+z) crossing the row scan drive signal line (VGn, VGn+1, VGn+2, VGn+3, VGn+4, VGn+5 . . . VGn+z), so that the second sub-pixel of the second pixel group of each column of sub-pixels is charged and lighted row by row. Since the first sub-pixel of the first pixel group and the first sub-pixel of the second pixel group of each row lighted in the previous time period are the sub-pixel of the first polarity and discharged, and they gradually become darker from bright. Therefore, the overall brightness of the display panel is from brighter to darker, and the pixels of the array substrate are arranged in such way that the sub-pixels of the first polarity and the sub-pixels of the second polarity are arranged alternately along rows where they are located, and the first sub-pixel of the first pixel group of each row is in the same column as the first sub-pixel of the first pixel group of other rows, and the second sub-pixel of the first pixel group of each row is in the same column as the second sub-pixel of the first pixel group of other rows. The first sub-pixel of the second pixel group of each row is in the same column as the first sub-pixel of the second pixel group of other rows, and the second sub-pixel of the second pixel group of each row is in the same column as the second sub-pixel of the second pixel group of other rows, so that the lighted sub-pixels are arranged alternately in columns. The array substrate on a whole seems to be lighted unevenly, thus one brighter row of sub-pixels and one darker row of sub-pixels are avoided. It is effectively avoided that there is not lighted sub-pixel, and the stability of uniform display is improved.
