As shown in fig. 2, based on the schematic structural diagram of the display panel 1 provided in fig. 1, the display panel 11 includes i scan lines, u scan lines, i×u/6 first pixels and i×u/6 second pixels, the first pixels and the second pixels are arranged in an array form and are arranged at intervals in a row direction, each first pixel includes a first sub-pixel, a second sub-pixel and a third sub-pixel sequentially arranged in the row direction, each second pixel includes a first sub-pixel, a second sub-pixel and a third sub-pixel sequentially arranged in the row direction, and i, u is a positive integer;

It should be noted that fig. 2 only illustrates two sets of adjacent first pixels 110 and second pixels 120, each row of pixels is formed by multiple sets of adjacent first pixels and second pixels, and the array structure of the display panel is formed by multiple rows of pixels.
In application, the colors of the first sub-pixels 111, 121, the second sub-pixels 112, 122 and the third sub-pixels 113, 123 in the first pixel and/or the second pixel may be different from each other to display different colors when being lightened, and specifically, the first sub-pixels 111, 121, the second sub-pixels 112, 122 and the third sub-pixels 113, 123 may be Red sub-pixels, green sub-pixels and Blue sub-pixels, respectively, to form an RGB Color Mode (Red-Green-Blue Color Mode). For example, the first sub-pixels 111, 121 are red sub-pixels, the second sub-pixels 112, 122 are green sub-pixels, and the third sub-pixels 113, 123 are blue sub-pixels; alternatively, the first sub-pixels 111 and 121 are green sub-pixels, the second sub-pixels 112 and 122 are red sub-pixels, and the third sub-pixels 113 and 123 are blue sub-pixels. In addition, the first sub-pixels 111, 121 in the first pixel 110 and the second pixel 120 are the same in color, the second sub-pixels 112, 122 in the first pixel 110 and the second pixel 120 are the same in color, and the third sub-pixels 113, 123 in the first pixel 110 and the second pixel 120 are the same in color. The specific colors of the first sub-pixels 111, 121, the second sub-pixels 112, 122 and the third sub-pixels 113, 123 in the first pixel 110 and/or the second pixel 120 are not limited in the embodiments of the present application.
In application, the polarity of any one sub-pixel when turned on is determined according to the polarity of the source driving signal output by the connected data line, and the polarities of the source driving signals output by the adjacent data lines are opposite, for example (as shown in fig. 2), the first data line 310 outputs a source driving signal of positive polarity, the second data line 320 outputs a source driving signal of negative polarity, and the third data line 330 outputs a source driving signal of positive polarity.
In application, each sub-pixel is electrically connected with the data line and the scanning line through the electronic switch 400, and the electronic switch 400 is used for being turned on when receiving the gate driving signal output by the scanning line, and is also used for receiving the source driving signal output by the data line and sending the source driving signal to the sub-pixel; the electronic switch 400 is also configured to turn off when the gate driving signal output from the scan line is not received, and stop sending the source driving signal to the sub-pixel. The electronic switch 400 may control each sub-pixel to be turned on or off according to whether a gate driving signal is received. Wherein the electronic switch 400 may be a triode or a metal oxide semiconductor field effect transistor (Metal Oxide Semiconductor Field Effect Transistor, MOSFET), in particular a thin film field effect transistor (Thin Film Transistor, TFT)
In one embodiment, a parasitic capacitance 124 is connected between the second sub-pixel 122 and the third sub-pixel 123 in the second pixel 120.
In the application, taking a group of adjacent first pixels 110 and second pixels 120 as an example, the parasitic capacitance 124 connected between the second sub-pixels 122 and the third sub-pixels 123 in the second pixels 120 causes the driving voltage of the third sub-pixels 123 in the second sub-pixels 120 to decrease, thereby causing the brightness to decrease, and further causing the brightness of the pixels in the same row to decrease, and the reason for the moire phenomenon formed on the display panel will be described below:
in the first period, the first scan line 210 outputs the gate driving signal, and the first data line 310, the second data line 320, and the third data line 330 sequentially output the source driving signal according to the control of the processor, the first sub-pixels 111 and 121 in the first pixel 110 and the second pixel 120 are charged and turned on, and the third sub-pixel 123 in the second pixel 120 is charged and turned on;
in the second period, the second scan line 220 outputs the gate driving signal, and the first, second and third data lines 310, 320, 330 sequentially output the source driving signal according to the control of the processor, the second sub-pixels 112, 122 in the first and second pixels 110, 120 are charged and turned on, and the third sub-pixel 123 in the third pixel 120 is charged and turned on;
Any two sub-pixels connected on the same data line, due to the fact that the interval distance is too short, parasitic capacitance is easy to form at the interval, so that when one sub-pixel of the any two sub-pixels is charged firstly through a source driving signal, the source driving signal is consumed to charge the parasitic capacitance at the same time, the driving voltage of one sub-pixel of the any two sub-pixels is reduced, brightness is reduced, the first sub-pixels 111 and 121 of the first pixel 110 and the second pixel 120 are charged and lightened in the same time period (first time period), and even if the brightness is reduced, the brightness of the two first sub-pixels 111 and 121 is kept consistent; the second sub-pixels 112, 122 in the first pixel 110 and the second pixel 120 are also charged and lighted in the same period of time (second period of time) in which the parasitic capacitance is fully charged, and the brightness of the two second sub-pixels 112, 122 is normal and kept uniform;
and the third sub-pixel 123 in the second pixel 120 is charged and turned on in the first period, the brightness is reduced, the third sub-pixel 113 in the first pixel 110 is charged and turned on in the second period, the brightness is normal, the brightness of the third sub-pixel 123 with the same color is lower than that of the third sub-pixel 113, and under the array structure of the display panel, the brightness of the third sub-pixel 123 in the same column is lower than that of the third sub-pixel 113 in the adjacent column, so that the moire phenomenon is formed on the display panel.
It should be noted that, fig. 2 illustrates an array structure of a display panel that may form a moire phenomenon on the display panel, and in a display panel adopting a dual-gate architecture, when charging periods of sub-pixels of any one or more colors located in the same row are different, the sub-pixel that is charged first is easily affected by parasitic capacitance to make brightness lower than that of the sub-pixel that is charged later, so that the moire phenomenon is formed on the display panel. The second and third embodiments described below provide a driving method based on the array structure of the display panel shown in the first embodiment, so as to eliminate the moire phenomenon formed on the display panel.

step S301, determining whether the current sub-pixel is the third sub-pixel in the second pixel according to the source driving signal and the gate driving signal.
In application, the processor (specifically, the timing controller) outputs a source driving signal by controlling one data line, and outputs a gate driving signal by controlling one scan line, so that a current sub-pixel connected to the one data line and the one scan line is charged and turned on. The processor may determine a specific position of the current sub-pixel in the display panel according to a serial number of the data line through which the source driving signal flows and a serial number of the scan line through which the gate driving signal flows, so as to determine whether the current sub-pixel is a third sub-pixel in the second pixel.
In application, each row of pixels of the display panel comprises a plurality of groups of first pixels and second pixels, the first pixels and the second pixels are arranged at intervals, and the positions of the first pixels and the second pixels in the display panel can be determined according to the array structure of the display panel.
Specifically, whether the sub-pixel of any column of the display panel is the sub-pixel of the first pixel (or the second pixel) can be determined, for example, when the sub-pixel of the first column of the display panel is the sub-pixel of the first pixel, the sub-pixel of the 6k-2 column, the sub-pixel of the 6k-1 column and the sub-pixel of the 6k column of the display panel are the first sub-pixel, the second sub-pixel and the third sub-pixel of the second pixel respectively, and the sub-pixel of the 6k-5 column, the 6k-4 column and the sub-pixel of the 6k-3 column of the display panel are the first sub-pixel, the second sub-pixel and the third sub-pixel of the first pixel respectively; or when the first column of the display panel is the sub-pixel of the second pixel, the 6k-2 th column, the 6k-1 th column and the 6k th column of the display panel are the first sub-pixel, the second sub-pixel and the third sub-pixel of the first pixel respectively, and the 6k-5 th column, the 6k-4 th column and the 6k-3 th column of the display panel are the first sub-pixel, the second sub-pixel and the third sub-pixel of the second pixel respectively. Wherein k is a positive integer.
In one embodiment, step S301 includes:
determining the column sequence number of the current sub-pixel according to the source electrode driving signal and the grid electrode driving signal;
and determining whether the current sub-pixel is a third sub-pixel in the second pixel according to the column serial number of the current sub-pixel.
In an application, the processor may determine the column number of the current subpixel according to the number of the data line through which the source driving signal flows and the number of the scan line through which the gate driving signal flows.
In application, when the 6 k-th column sub-pixel of the display panel is the third sub-pixel of the second pixel, judging whether the column number of the current sub-pixel belongs to 6k, if so, determining that the current sub-pixel is the third sub-pixel of the second pixel, and if not, determining that the current sub-pixel is not the third sub-pixel of the second pixel; or when the 6k-3 th column sub-pixel of the display panel is the third sub-pixel of the second pixel, judging whether the column serial number of the current sub-pixel belongs to 6k-3, if so, determining that the current sub-pixel is the third sub-pixel of the second pixel, and if not, determining that the current sub-pixel is not the third sub-pixel of the second pixel.
In one embodiment, after step S301, it includes:
if the current sub-pixel is not the third sub-pixel in the second pixel, the current sub-pixel is driven by the source driving signal.
In application, if the current sub-pixel is not the third sub-pixel in the second pixel, the brightness of the current sub-pixel and the sub-pixel with the same color as the current sub-pixel in the same row can be kept consistent, no vertical stripe phenomenon can be formed on the display panel, and the current sub-pixel can be directly driven by the source driving signal.
Step S302, if the current sub-pixel is the third sub-pixel in the second pixel, the gray level difference between the current sub-pixel and the second sub-pixel of the second pixel adjacent to the current sub-pixel is obtained.
In application, after determining that the current sub-pixel is the third sub-pixel in the second pixel, it is explained that the current sub-pixel is susceptible to parasitic capacitance, resulting in a reduction of the driving voltage, and thus resulting in a sub-pixel of the same color, i.e. the third sub-pixel in the first pixel, that is lower in brightness than the post-charge of the same row.
In application, the gray level of the current sub-pixel can be obtained when the current sub-pixel is lightened, the gray level of the second sub-pixel of the second pixel adjacent to the current sub-pixel can be obtained when the second sub-pixel of the second pixel adjacent to the current sub-pixel is lightened, and the gray level of the second sub-pixel of the second pixel adjacent to the current sub-pixel is subtracted from the gray level of the current sub-pixel to obtain the gray level difference. It should be noted that, the gray level of the second sub-pixel of the second pixel adjacent to the current sub-pixel reflects the gray level when the brightness of the current sub-pixel is normal, so the influence of the parasitic capacitance on the brightness of the current sub-pixel can be quantified according to the calculated gray level difference.
In one embodiment, step S302 includes:
if the current sub-pixel is the third sub-pixel in the second pixel, acquiring the gray level of the current sub-pixel and the gray level of the second sub-pixel of the second pixel adjacent to the current sub-pixel through the image measuring instrument;

In application, the gray scale of the current sub-pixel and the gray scale of the second sub-pixel of the second pixel adjacent to the current sub-pixel can be obtained through the image measuring instrument, and the gray scale difference between the current sub-pixel and the second sub-pixel of the second pixel adjacent to the current sub-pixel is calculated through the processor.
In one embodiment, step S302 includes:
if the current sub-pixel is the third sub-pixel in the second pixel, the gray scale of the current sub-pixel and the gray scale of the second sub-pixel of the second pixel adjacent to the current sub-pixel are read by the processor.
In an application, the processor may specifically be a timing controller, where the timing controller may read the gray information in the source driving signal when outputting the source driving signal, so as to determine a first preset gray of the current subpixel and a second preset gray of a second subpixel of a second pixel adjacent to the current subpixel. It should be noted that, the brightness of the second sub-pixel of the second pixel adjacent to the current sub-pixel is normal when the second sub-pixel is lighted, so that the gray level of the second sub-pixel of the second pixel adjacent to the current sub-pixel is equal to the first preset gray level; and the brightness of the current sub-pixel is reduced when the current sub-pixel is lightened, and the gray level of the current sub-pixel is smaller than the second preset gray level.
In application, the timing controller can acquire the voltage value on the current sub-pixel after the current sub-pixel is lightened, and determine the gray level of the current sub-pixel according to the voltage value on the current sub-pixel, so as to avoid acquiring the gray level information with errors according to the source driving signal.
Step S303, calculating the voltage compensation value of the source driving signal according to the gray level difference between the current sub-pixel and the second sub-pixel of the second pixel adjacent to the current sub-pixel, the parasitic capacitance and the capacitance of the current sub-pixel.
In one embodiment, the calculation formula for calculating the voltage compensation value of the source driving signal in step S303 is as follows:
Gain=ΔLv*C p2p3 /C p3 ;
wherein Gain represents a voltage compensation value of the source driving signal, deltaLv represents a gray scale difference between the current sub-pixel and a second sub-pixel of a second pixel adjacent to the current sub-pixel, C p2p3 Representing a parasitic capacitance value between the current subpixel and a second subpixel of a second pixel adjacent to the current subpixel, C p3 Representing the capacitance value of the current sub-pixel.
In application, the capacitance of the current sub-pixel is determined according to the actual type of the third sub-pixel of the second pixel; the parasitic capacitance between the current sub-pixel and the second sub-pixel of the second pixel adjacent to the current sub-pixel may be obtained by table lookup, specifically, before calculating the voltage compensation value of the source driving signal, the parasitic capacitance value between the third sub-pixel and the second sub-pixel in each second pixel of the display panel may be detected, and a table corresponding to each second pixel and the parasitic capacitance value may be formed.
In the application, the gray level difference between the current sub-pixel and the second sub-pixel of the second pixel adjacent to the current sub-pixel is substituted into calculation, and the voltage compensation value of the source driving signal can be calculated according to the influence of the parasitic capacitance on the brightness of the current sub-pixel.

In general, the smaller the separation distance between the current subpixel and the second subpixel of the second pixel adjacent to the current subpixel, the larger the parasitic capacitance value. When driving different display panels, the parasitic capacitance value between the current sub-pixel and the second sub-pixel of the second pixel adjacent to the current sub-pixel can be determined according to the interval distance between the current sub-pixel and the second sub-pixel of the second pixel adjacent to the current sub-pixel, the resistance-capacitance parameter of the current sub-pixel and the resistance-capacitance parameter of the second sub-pixel of the second pixel adjacent to the current sub-pixel.

In application, the processor can add the calculated voltage compensation value with the initial voltage of the source driving signal, compensate the voltage of the source driving signal, improve the brightness of the current sub-pixel, and enable the brightness of the current sub-pixel, which is reduced due to the influence of parasitic capacitance, to be restored to normal brightness, so as to eliminate the vertical stripe phenomenon of the display panel.
