Example one
Referring to fig. 1, fig. 1 is a schematic flow chart of a display panel driving method according to a first embodiment of the invention. As shown in fig. 1, in the present embodiment, the display panel driving method includes:
step S10: in the first phase, providing a corresponding data signal to each data line, and charging a first pixel corresponding to each data line, wherein the data signal is continuously at a high level or a low level in the first phase, and the charging level of the first pixel is the same as the level of the data signal in the first phase.
It should be noted that, in the first stage, providing corresponding data signals to the data lines means: when in the first stage, data signals corresponding to the respective data lines are simultaneously provided to each data line, and the level of the data signal corresponding to each data line may be different, but the data signals are continuous high level signals or continuous low level signals, for example: the data signal of the data line a is at a sustained and constant high level in the first phase, and the data signal of the data line B is at a sustained and constant low level in the first phase. Wherein the first stage refers to a period of time from when the data signal is input to display one frame of picture until the data signal is inverted.
In this embodiment, the first pixels refer to all the pixels on the respective data lines having the same charge level as the data signal, and there may be any number of the first pixels, depending on the arrangement of the pixels on the display panel.
In a specific implementation, a corresponding data signal is provided to each data line in the first phase, so that the first pixels on each data line can be charged, and the data signal does not change in the first phase, and is a fixed high-level signal or a fixed low-level signal.
Further, as shown in fig. 2, in the display panel architecture in this embodiment, two scanning lines are disposed between two adjacent rows of pixels, each row of pixels includes a third pixel and a fourth pixel, the third pixel and the fourth pixel are disposed in an interleaved manner, the third pixel is connected to the scanning line disposed above the row of pixels, the fourth pixel is connected to the scanning line disposed below the row of pixels, and the adjacent third pixel and the adjacent fourth pixel are connected to the same data line.
It should be noted that each pixel in each row of pixels is one of the third pixel and the fourth pixel, two adjacent pixels of each third pixel in the same row of pixels are the fourth pixels, and two adjacent pixels of each fourth pixel are the third pixels.
In this embodiment, the same data line connecting the adjacent third pixel and the fourth pixel is located on the left side of the third pixel and the fourth pixel, or on the left side of the third pixel and the fourth pixel, that is, the same data line connecting the adjacent third pixel and the fourth pixel is located on the same side of the third pixel and the fourth pixel.
Further, in this embodiment, the level of the data signal in the first stage is the same as the charge level of the pixels corresponding to the first row of scanning lines. The first row of scanning lines is determined according to a scanning order of the display panel in one frame, for example: when the scanning sequence of the display panel is from top to bottom, the first row of scanning lines is the uppermost row of scanning lines of the display panel; when the scanning sequence of the display panel is from bottom to top, the first row of scanning lines is a lowermost row of scanning lines of the display panel.
Note that, the fact that the level of the data signal in the first phase is the same as the charge level of the pixel corresponding to the first row of the scanning line means that: in the first stage, the level of the data signal of each data line depends on the charging level of the pixels of the data line on the first row of scanning lines. For example: in the first stage, when the charging level of the pixel of the data line B on the first row of the scan line is a high level, the data signal corresponding to the data line B is also a high level; in the first phase, when the charging level of the pixel on the first row of the scan line of the data line C is low, the data signal corresponding to the data line C is also low.
Further, in a specific implementation, in the first phase, a first scan line is turned on, and a charge level of a pixel corresponding to the first scan line is the same as a charge level of a pixel corresponding to the first scan line. The charging level of the pixels corresponding to all the data lines on the first scanning line is the same as the charging level of the pixels corresponding to each data line on the first scanning line. For example: in the first stage, when the pixels of the data line D on the first row of scan lines are at high level, the scan lines on which all the pixels of the data line D at high level are located are the first scan lines. The first scanning line also comprises a first row of scanning lines.
It should be noted that, the specific starting sequence of the first scan line may be: and sequentially starting all the first scanning lines from top to bottom or from bottom to top.
Further, in this embodiment, in the second phase, a second scan line is turned on, and a charge level of a pixel corresponding to the second scan line is opposite to a charge level of a pixel corresponding to the first scan line. The charging level of the pixels corresponding to all the data lines on the second scanning line is opposite to the charging level of the pixels corresponding to all the data lines on the first scanning line. For example: in the first phase, when the pixels of the data line E on the scan line of the first row are at the high level, the scan lines on which all the pixels at the low level on the same data line (i.e., the data line E) are located are the second scan lines.
In a specific implementation, the specific turn-on sequence of the second scan line may be: and sequentially opening all the second scanning lines from top to bottom or from bottom to top.
Further, the charging levels of the pixels corresponding to the odd-numbered scanning lines are the same, and the charging levels of the pixels corresponding to the even-numbered scanning lines are the same. The odd-numbered scanning lines refer to the 1 st, 3 rd, 5 th, and 7 th scanning lines from top to bottom or from bottom to top according to the scanning order of the display panel. The even-numbered rows of scanning lines refer to the 2 nd, 4 th, 6 th, 8 th, etc., from top to bottom or from bottom to top in the scanning order of the display panel.
In this embodiment, the charging levels of the pixels corresponding to the odd-numbered scanning lines are the same, and the charging levels of the pixels corresponding to the even-numbered scanning lines are the same: the charging levels of all the pixels in the same column and the same data line on the odd-numbered scanning lines are the same on average and are all high level at the same time or low level at the same time. The charging levels of all pixels in the same column and the same data line on even rows of scanning lines are the same on average and are all high level at the same time or low level at the same time.
Step S20: and in the second stage, the level of each data signal is inverted, and second pixels corresponding to each data line are charged, wherein the charging level of the second pixels is the same as the level of the data signals in the second stage.
In the second stage, inverting the level of each data signal means: when the first phase is completed, the second phase is entered, and then the levels of the corresponding data signals supplied to the respective data lines are inverted, for example: when the data signal of the data line A is at a high level in the first stage, the data signal of the data line A is switched to a low level in the second stage; when the data signal of the data line a is at a low level in the first stage, the data signal of the data line a is switched to a high level in the second stage. Further, in the second phase, the data signals of the data lines may also be at different levels, but the data signals are all continuous, fixed high level or low level, for example: the data signal of the data line a is at a sustained and unchanging high level in the second phase, and the data signal of the data line B is at a sustained and unchanging low level in the second phase. Wherein the second phase refers to a period of time until all the second pixels are completely charged after the data signal is inverted when one frame of a picture is displayed.
In this embodiment, the second pixels are all pixels having the same charge level as the data signal in the second stage on each data line, and the number of the second pixels may be arbitrarily large, and is determined by the arrangement of the pixels on the display panel. And the first pixel and the second pixel are added up to be all pixels on the display panel, that is, all pixels on the display panel are necessarily the first pixel or the second pixel. The first pixel and the second pixel have opposite levels.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a pixel structure according to the present invention. Where S1-S9 are scan lines and D1-D6 are data lines, the numbers 1-8 in the figure represent 8 pixels on the D2 data line, respectively, where the charge levels of pixels 1, 2, 3, 4 are high and the charge levels of pixels 5, 6, 7, 8 are low. As shown in fig. 2, the pixel structure of the display panel of the present invention is that, starting from the first pixel of each row, every two pixels of the same row connect to the same data line, such as pixel 1 and pixel 5, and there are two scan lines on both upper and lower sides of each row of pixels, and two adjacent pixels of the same row connecting to the same data line connect to the scan lines on the upper and lower sides, such as pixel 1 connects to scan line S1, and pixel 5 connects to scan line S2, respectively.
It should be noted that fig. 3 is an actual waveform diagram of the display panel driving method of the present embodiment, and referring to fig. 2 and fig. 3, taking one of the data lines D2 as an example, S1-S8 are 8 scan lines from top to bottom, where the charge levels of the pixels on S1, S3, S5, and S7 are high levels, and the charge levels of the pixels on S2, S4, S6, and S8 are low levels. Therefore, the display panel driving method of the present embodiment first provides a high-level data signal to the data line D2 in the first stage, then turns on the first scan lines S1, S3, S5, and S7 to charge the first pixel with the high-level charge level, then provides a low-level data signal to the data line D2 in the first stage, and turns on the second scan lines S2, S4, S6, and S8 to charge the second pixel with the low-level charge level. Compared with the conventional method of repeatedly switching the levels of the data signals according to the scanning sequence of S1-S8, the method can realize that all pixels are charged by only switching the high level and the low level once according to the waveform of the actual data line, reduce frequent driving voltage switching of high voltage and low voltage, and greatly reduce the occurrence rate that the actual charged pixel voltage is less than the theoretical voltage due to RC loading during pixel charging.
In this embodiment, in a frame period, not only the first stage and the second stage may be included, but also the first pixels corresponding to the first stage may be grouped, the second pixels corresponding to the second stage are grouped, and then the charging stage in the frame period is divided into a plurality of charging stages, that is, the number of times of turning the high level and the low level of each charging period is increased, that is, the pixels are charged in groups alternately according to the sequence of the high level, the low level and the high level. For example: when the charge level of the pixels at S1, S3, S5, S7 is high level and the charge level of the pixels at S2, S4, S6, S8 is low level, the charging order is set to S1S 3, S2S 4, S5S 7, S6S 8, or the number of pixels in each charging group can be flexibly adjusted, for example: S1S 3S 5, S2S 4, S7, S6S 8, and the number of pixels of the specific first pixel or second pixel in each charging group is not limited, and may be set by the user according to the driving manner. The method realizes the flexible grouping charging of the first pixel with high level and the second pixel with low level, thereby not only flexibly configuring the charging sequence of the pixels when displaying the picture, but also reducing the frequent switching of high and low voltages of the data signals, greatly reducing the occurrence rate that the actual charging sub-pixel voltage of the pixel is smaller than the theoretical voltage, and improving the accuracy of the actual signal charging pixel.
In this embodiment, in the first phase, a corresponding data signal is provided to each data line to charge a first pixel corresponding to each data line, the data signal continues to be at a high level or a low level in the first phase, and the charge level of the first pixel is the same as the level of the data signal in the first phase; and in the second stage, the level of each data signal is inverted, and second pixels corresponding to each data line are charged, wherein the charging level of the second pixels is the same as the level of the data signals in the second stage. The method and the device realize that each frame of picture is divided into two stages, and then only the data signals with the same level and continuity are provided for the data lines in each stage, so that the first pixels with the same charging level are charged firstly, and then the second pixels with the same charging level are charged, frequent switching of high voltage and low voltage of the data signals is reduced, the occurrence rate that the actual charging sub-pixel voltage of pixel charging is smaller than the theoretical voltage is greatly reduced, and the accuracy of the actual signal charging pixel is improved.
Example two
Referring to fig. 4, fig. 4 is a schematic structural diagram of a display panel according to the present invention. In order to achieve the above object, the present invention further provides a display panel.
In this embodiment, the display panel includes an array substrate 40, a source driving circuit 50, a gate driving circuit 60, and a timing controller 70, wherein a plurality of data lines 10 and pixels 30 with scanning lines 20 distributed in an array are disposed on the array substrate 40, each pixel 30 on the same scanning line is respectively connected to the data line 10 and respectively connected to different scanning lines 20 above and below, the source driving circuit 50 is connected to the data line 10, the gate driving circuit 60 is connected to the scanning lines 20, and the timing controller 70 is respectively connected to the source driving circuit 50 and the gate driving circuit 60. The display panel has a first stage and a second stage which are sequentially performed in one frame period; the source driving circuit 50 is configured to provide a corresponding data signal to each data line 10 in the first phase, and charge a first pixel corresponding to each data line, where the data signal is continuously at a high level or a low level in the first phase, and a charge level of the first pixel is the same as a level of the data signal in the first phase; the source driving circuit 10 is further configured to invert the level of each data signal in the second phase to charge the second pixel corresponding to each data line 10, where the charge level of the second pixel is the same as the level of the data signal in the second phase.
It should be noted that, in the first stage, the source driving circuit 10 provides the corresponding data signal to each data line 10, which means: when in the first stage, each data line 10 is simultaneously provided with the data signal corresponding to each data line 10, and the data signal corresponding to each data line may be different, but the data signals are all continuous high level signals or continuous low level signals.
In this embodiment, the first pixel refers to all the pixels 30 having the same charge level as the data signal on each data line 10, and there may be any number of the first pixels, depending on the arrangement of the pixels 30 on the display panel.
In a specific implementation, the source driving circuit 10 provides a corresponding data signal to each data line 10 in the first phase, so that the first pixels on each data line can be charged, and the data signal does not change in the first phase, and is a fixed high level signal or a fixed low level signal.
Further, in a specific implementation, the gate driving circuit 60 is configured to turn on a first scan line in the first phase, where a charge level of a pixel corresponding to the first scan line is the same as a charge level of a pixel corresponding to a first row of scan lines. The charge level of the pixels 30 corresponding to all the data lines 10 on the first scan line is the same as the charge level of the pixels 30 corresponding to each data line 10 on the first scan line. For example: in the first phase, when the pixels of the data line D on the first row of scan lines are at the high level, the scan line on which all the pixels of the data line D at the high level are located is the first scan line. The first scanning line also comprises a first row of scanning lines.
It should be noted that, the specific starting sequence of the first scan line may be: and sequentially starting all the first scanning lines from top to bottom or from bottom to top.
