In order to solve the vertical stripe phenomenon of the display panel during displaying, the inventor has conducted the following research on the display panel provided by the prior art:
fig. 1 is a schematic structural diagram of a display panel according to the prior art. Referring to fig. 1, the display panel includes a plurality of gate line groups 1 and a pixel array 2;
the pixel array 2 includes a plurality of pixel rows 3 and a plurality of pixel columns 4; wherein the pixel row 3 comprises a plurality of pixels 5 arranged along a first direction X, the pixel column 4 comprises a plurality of pixels 5 arranged along a second direction Y, the first direction X and the second direction Y intersect; the gate line group 1 includes two gate lines, namely a gate line 6A and a gate line 6B, which are adjacently disposed, and the gate lines extend along a first direction X; the pixel 5 includes a first pixel 7 and a second pixel 8; the pixel rows 3 and the gate line groups 1 are arranged in a one-to-one correspondence manner, and the adjacent first pixels 7 and second pixels 8 in the same pixel row 3 are respectively and electrically connected with different gate lines in the same gate line group 1; two gate lines in the gate line group 1 are oppositely arranged on two sides of the corresponding pixel row 3 along the second direction Y.
In the display panel provided by the prior art, a driving signal is provided to the gate line in the gate line group 1, so as to turn on the pixel 5 in the pixel row 3 corresponding to the gate line group 1, specifically, the driving signal is provided to the gate line 6A, the second pixel 8 is turned on, and then the driving signal is provided to the gate line 6B, and the first pixel 7 is turned on. When the driving signal of the gate line 6B is terminated, the driving signal is coupled to the second pixel 8, so that the potential of the second pixel 8 deviates from the initially set potential, and the luminance of the second pixel 8 is abnormal, and a display failure such as a vertical stripe may occur when the display panel displays. For example, when the driving signal of the gate line is a high-level signal, the falling edge of the driving signal of the gate line 6B is coupled to the second pixel 8, so that the potential of the second pixel 8 is pulled down; when the driving signal of the gate line is a low level signal, the rising edge of the driving signal of the gate line 6B is coupled to the second pixel 8, thereby pulling up the potential of the second pixel 8. The second pixel 8 cannot display the predetermined brightness when the potential of the second pixel 8 is pulled high or low, so that the display panel may have poor display such as vertical stripes during displaying.
In view of the above, the present invention provides a display panel, a driving method thereof and a display device, so as to solve the problem of poor display, such as a vertical stripe phenomenon, occurring when the display panel is used for displaying. The present invention will be described in detail with reference to specific examples.
Referring to fig. 2 and fig. 3, fig. 2 is a schematic plan view illustrating a display panel in a driving method according to an embodiment of the invention; FIG. 3 is a timing diagram of scan lines in the display panel shown in FIG. 2;
the embodiment of the invention provides a driving method of a display panel, wherein the display panel comprises the following steps: a display area AA;
the display area AA includes a plurality of subpixels P arranged in an array;
the sub-pixel P includes a first sub-pixel P1 and a second sub-pixel P2, the first sub-pixel P1 and the second sub-pixel P2 being alternately arranged in the first direction X to form a pixel row PX;
a plurality of scan lines GL extending in the first direction X, the scan lines GL including a first scan line GL1 and a second scan line GL 2;
the display area AA includes a plurality of row repeating units 100 arranged in the second direction Y, and the row repeating units 100 include: one first scanning line GL1, one second scanning line GL2, and one pixel row PX;
in the same row repeating unit 100, the first scanning line GL1 and the second scanning line GL2 are respectively located at two opposite sides of the pixel row PX in the second direction Y, the first scanning line GL1 is electrically connected to the gate of the driving switch ST of the first sub-pixel P1, and the second scanning line GL2 is electrically connected to the gate of the driving switch ST of the second sub-pixel P2; in the same frame, there is an overlap between the scan signal of the first scan line GL1 and the scan signal of the second scan line GL2, and the scan signal of the second scan line GL2 is turned on and off later than the scan signal of the first scan line GL 1;
a plurality of data lines DL extending in the second direction Y;
the driving method comprises the following steps:
receiving an initial data signal;
compensating the initial data signal and outputting a compensated data signal to the data line DL;
for the first and second sub-pixels P1 and P2 electrically connected to the same data line DL in the same pixel row PX, the initial data signal of the first sub-pixel P1 is V0 in the same frame1The initial data signal of the second sub-pixel P2 is V02The compensation data signal of the first sub-pixel P1 is V11The compensated data signal of the second sub-pixel P2 is V12(ii) a When the scanning signal of the scanning line GL is at a high level, V11-V12>V01-V02(ii) a V1 when the scanning signal of the scanning line GL is at low level1-V12＜V01-V02。
In this embodiment, the display panel has a dual gate line structure, and two scan lines GL are disposed between two adjacent pixel rows PX. Specifically, two scanning lines GL are provided for driving the same pixel row PX, the scanning lines GL including the first scanning line GL1 and the second scanning line GL2, the first scanning line GL1 and the second scanning line GL2 being respectively located on opposite sides of the pixel row PX driven thereby in the second direction Y. The first scan line GL1 is electrically connected to the gate of the driving switch ST of the first sub-pixel P1, for driving the first sub-pixel P1 in the pixel row PX. The second scan line GL2 is electrically connected to the gate of the driving switch ST of the second sub-pixel P2, for driving the second sub-pixel P2 in the pixel row PX.
Because the number of the scanning lines in the display panel with the dual-gate line structure is large, the time for each corresponding scanning line to receive the scanning signal is reduced under the condition that the refreshing frequency of the display panel is the same, and if the time for the scanning signal of the scanning line is too short, the corresponding on-time of the driving switch ST is too short, the sub-pixel charging is possibly insufficient, and the display abnormity occurs. In this embodiment, in order to avoid the display abnormal phenomenon, in the same frame, the scan signal of the first scan line GL1 and the scan signal of the second scan line GL2 are overlapped, so that the scan signals have enough time (i.e. the pulse width of the scan signals is large), and the problem of insufficient charging of the sub-pixels is avoided. In addition, the scanning signal of the first scanning line GL1 and the scanning signal of the second scanning line GL2 are not synchronized, the scanning signal of the second scanning line GL2 is turned on and off later than the scanning signal of the first scanning line GL1, and usually the pulse widths of the scanning signal of the first scanning line GL1 and the scanning signal of the second scanning line GL2 are the same, and it should be noted that, for a solution with special requirements or improvements, the pulse widths of the scanning signal of the first scanning line GL1 and the scanning signal of the second scanning line GL2 are different, but it is also a protected range that the scanning signal of the second scanning line GL2 is turned on and off later than the scanning signal of the first scanning line GL1, and the invention is not limited thereto.
In this embodiment, only the case where the scanning signal is a high level signal will be described. In other alternative embodiments of the present invention, the scan signal may also be a low level signal, and the detailed description of this embodiment is omitted.
At the time T0 after the end of the scan signal of the first scan line GL1, the scan signal is still transmitted on the second scan line GL 2. At time T0, when the first subpixel P1 electrically connected to the first scanning line GL1 has been charged and is in a floating state, the falling edge of the scanning signal of the second scanning line GL2 (the portion circled by the dotted line in fig. 3) will pull the electrical signal of the first subpixel P1 low, and the brightness of the first subpixel P1 is abnormal.
The display panel further includes a plurality of data lines DL extending in the second direction Y, and optionally, the first sub-pixel P1 and the second sub-pixel P2 adjacent to each other in the same pixel row PX are electrically connected to the same data line DL. The data line DL is used to transmit an electrical signal to the subpixel P to control the luminance of the subpixel P. Alternatively, the electrical signal of the data line DL may be provided by a chip mounted on the display panel or a processor external to the display panel, which is not particularly limited in this embodiment.
For a display panel with a dual gate line structure, the driving method provided by the embodiment includes:
receiving an initial data signal; the initial data signal is a data signal corresponding to the luminance to be displayed by the subpixel P without considering the influence of the driving signal of the gate line on the subpixel.
Compensating the initial data signal and outputting a compensated data signal to the data line DL; the compensation data signal is an actual compensation data signal which is provided for the sub-pixel to compensate the initial data signal of the sub-pixel according to the actual display condition of the display panel and the influence condition of the driving signal of the gate line on the sub-pixel, so as to improve the abnormal brightness phenomenon of the sub-pixel.
When the scanning signal of the scanning line GL is high, the initial data signals of the first sub-pixel P1 and the second sub-pixel P2 electrically connected to the same data line DL in the same pixel row PX are the same (i.e. V0)1-V020) is an example, and the present embodiment will be specifically explained.
Since the scanning signal of the scanning line GL is at a high level, the falling edge of the scanning signal of the second scanning line GL2 pulls the potential of the first sub-pixel P1 low. In this embodiment, the initial data signals of the first sub-pixel P1 and the second sub-pixel P2 are compensated, and the compensated data signals are provided to the first sub-pixel P1 and the second sub-pixel P2, so as to improve the problem of the potential pull-down of the first sub-pixel P1.
For example, a higher than initial data signal V0 is provided to the first subpixel P11Compensated data signal V11And the compensation data signal V1 of the second sub-pixel P22Hold and initial data signal V02Similarly, the first sub-pixel P1 is pulled up to improve the abnormal brightness of the first sub-pixel P1, i.e., V11-V12>V01-V02。
Alternatively, the compensated data signal V1 of the first subpixel P1 may be set1Hold and initial data signal V01The same and a lower initial data signal V0 is supplied to the second sub-pixel P22Compensated data signal V12Therefore, the potential of the second sub-pixel P2 is pulled down to make the brightness of the second sub-pixel P2 tend to the first sub-pixel P1, and the abnormal brightness of the first sub-pixel P1, namely V1, can also be improved1-V12>V01-V02。
Still alternatively, a higher than initial data signal V0 is supplied to the first subpixel P11Compensated data signal V11And provides a lower than initial data signal V0 to the second sub-pixel P22Compensated data signal V12Simultaneously, the voltage level of the first sub-pixel P1 is pulled high and the voltage level of the second sub-pixel P2 is pulled low, so that the brightness of the second sub-pixel P2 tends to the first sub-pixel P1, and the abnormal brightness of the first sub-pixel P1, namely V1, can also be improved1-V12>V01-V02。
When the scanning signal of the scanning line GL is low, the initial data signals of the first sub-pixel P1 and the second sub-pixel P2 electrically connected to the same data line DL in the same pixel row PX are the same (i.e. V0)1-V020) is an example, and the present embodiment will be specifically explained. V11-V12＜V01-V02。
Since the scanning signal of the scanning line GL is at a low level, the falling edge of the scanning signal of the second scanning line GL2 pulls the potential of the first sub-pixel P1 high. In this embodiment, the initial data signals of the first sub-pixel P1 and the second sub-pixel P2 are compensated, and the compensated data signals are provided to the first sub-pixel P1 and the second sub-pixel P2, so as to improve the problem of the potential pull-up of the first sub-pixel P1.
For example, a lower than original data signal V0 is provided to the first subpixel P11Compensated data signal V11And the compensation data signal V1 of the second sub-pixel P22HoldingAnd an initial data signal V02Similarly, the potential of the first sub-pixel P1 is pulled down to improve the abnormal brightness of the first sub-pixel P1, i.e., V11-V12＜V01-V02。
Alternatively, the compensated data signal V1 of the first subpixel P1 may be set1Hold and initial data signal V01The same and supplies a higher initial data signal V0 to the second sub-pixel P22Compensated data signal V12Therefore, the potential of the second sub-pixel P2 is pulled high, the brightness of the second sub-pixel P2 tends to the first sub-pixel P1, and the abnormal brightness of the first sub-pixel P1, namely V1, can be improved1-V12＜V01-V02。
Still alternatively, a lower than original data signal V0 is supplied to the first subpixel P11Compensated data signal V11And provides a higher initial data signal V0 to the second sub-pixel P22Compensated data signal V12Simultaneously, the potential of the first sub-pixel P1 is pulled down, and the potential of the second sub-pixel P2 is pulled up, so that the brightness of the second sub-pixel P2 tends to the first sub-pixel P1, and the brightness abnormality of the first sub-pixel P1, namely V1, can also be improved1-V12＜V01-V02。
The driving method provided by the embodiment can at least achieve the following beneficial effects:
a driving method of a display panel of a dual gate line structure is provided, which receives an initial data signal, then compensates the initial data signal and outputs a compensation data signal to a data line DL; for the first and second sub-pixels P1 and P2 electrically connected to the same data line DL in the same pixel row PX, the initial data signal of the first sub-pixel P1 is V0 in the same frame1The initial data signal of the second sub-pixel P2 is V02The compensation data signal of the first sub-pixel P1 is V11The compensated data signal of the second sub-pixel P2 is V12(ii) a When the scanning signal of the scanning line GL is at a high level, V11-V12>V01-V02(ii) a V1 when the scanning signal of the scanning line GL is at low level1-V12＜V01-V02Therefore, the abnormal brightness of the sub-pixels is improved, the vertical stripe phenomenon of the display panel is improved, and the display quality is improved.
In some alternative embodiments, please continue with reference to fig. 2,
in the same frame, when the gray levels of the first subpixel P1 and the second subpixel P2 electrically connected to the same data line DL in the same pixel row PX are the same, the absolute value of the difference between the initial data signals is 0V, and the absolute value of the difference between the compensation data signals is Δ V.
In this embodiment, the gray scales of the first sub-pixel P1 and the second sub-pixel P2 are the same, that is, the required display luminances of the first sub-pixel P1 and the second sub-pixel P2 are the same, that is, the initial data signals of the two sub-pixels are the same.
The absolute value of the difference between the compensated data signals is set to Δ V so that the actual display luminance of the first and second sub-pixels P1 and P2 is substantially the same, thereby improving luminance abnormality of the sub-pixels and improving the moire phenomenon of the display panel.
It should be noted that the specific value of Δ V needs to be set according to the actual situation of the display panel, and the specific value of Δ V may be different for different display panels.
Specific examples of the specific distribution of Δ V are provided below.
In some alternative embodiments, with continued reference to fig. 2, a specific allocation of Δ V is:
for the first sub-pixel P1 and the second sub-pixel P2 electrically connected to the same data line DL in the same pixel row PX, the initial data signal and the compensation data signal of the second sub-pixel P2 are the same in the same frame;
when the scanning signal of the first scanning line GL1 and the scanning signal of the second scanning line GL2 are both high level signals, the compensation data signal of the first subpixel P1 is higher than the initial data signal by Δ V; when the scan signal is a high level signal, the potential of the first sub-pixel P1 is pulled down by the falling edge of the second scan line GL2, the compensation data signal of the first sub-pixel P1 is set to be higher than the initial data signal by Δ V, and the potential of the first sub-pixel P1 can be pulled up, thereby improving the luminance abnormality of the first sub-pixel.
When both the scanning signal of the first scanning line GL1 and the scanning signal of the second scanning line GL2 are low level signals, the compensation data signal of the first subpixel P1 is lower than the initial data signal by Δ V. When the scan signal is a low level signal, the potential of the first sub-pixel P1 is pulled high by the rising edge of the second scan line GL2, the compensation data signal of the first sub-pixel P1 is set to be lower than the initial data signal by Δ V, and the potential of the first sub-pixel P1 can be pulled low, thereby improving the luminance abnormality of the first sub-pixel.
In this embodiment, only the data signal of the first sub-pixel P1 is compensated, and the initial data signal and the compensation data signal of the second sub-pixel P2 are kept the same, so that the luminance anomaly of the first sub-pixel can be improved, and the display quality can be improved.
In some alternative embodiments, with continued reference to fig. 2, another specific allocation of Δ V is:
with respect to the first sub-pixel P1 and the second sub-pixel P2 electrically connected to the same data line DL in the same pixel row PX, in the same frame,

It is possible to pull up the potential of the first subpixel P1 and set the compensation data signal of the second subpixel P2 lower than the initial data signal
The luminance of the second sub-pixel P2 can be pulled down to make the luminance of the first sub-pixel P1 and the second sub-pixel P2 tend to be consistent, thereby improving the luminance abnormality of the sub-pixels.
When the scanning signal of the first scanning line GL1 and the scanning signal of the second scanning line GL2 are both low-level signals, the compensation data signal of the first subpixel P1 is lower than the initial data signal
The compensated data signal of the second subpixel P2 is higher than the initial data signal
When the scan signal is a low level signal, the potential of the first sub-pixel P1 is pulled high by the rising edge of the second scan line GL2, and the compensated data signal of the first sub-pixel P1 is set to be lower than the initial data signal
It is possible to pull down the potential of the first subpixel P1 and set the compensation data signal of the second subpixel P2 higher than the initial data signal
The luminance of the second sub-pixel P2 may be raised such that the luminance of the first sub-pixel P1 and the luminance of the second sub-pixel P2 tend to be uniform, thereby improving luminance abnormality of the sub-pixels.
In this embodiment, the data signals of the first sub-pixel P1 and the second sub-pixel P2 are compensated to make the luminances of the first sub-pixel P1 and the second sub-pixel P2 tend to be consistent, so that the luminance abnormality of the sub-pixels can be improved and the display quality can be improved.
In some alternative embodiments, with continued reference to fig. 2, another specific allocation of Δ V is:
for the first and second sub-pixels P1 and P2 electrically connected to the same data line DL in the same pixel row PX, the compensation data signal and the initial data signal of the first sub-pixel P1 are equal in the same frame;
