CROSS REFERENCE TO RELATED APPLICATION 
     The present application is the national stage of International Application with No. PCT/CN2019/124875, filed Dec. 12, 2019, which claims priority to Chinese Patent Application No. 201811608395.8, filed on Dec. 26, 2018, and entitled “DISPLAY PANEL DRIVING METHOD, DEVICE and READABLE STORAGE MEDIUM”, the entire content of which is hereby incorporated by reference. 
     TECHNICAL FIELD 
     The present application relates to the technical field of display, in particular to a driving method for display panel, a driving device for display panel and a display. 
     BACKGROUND 
     The statement herein only provides background information related to the present application and does not necessarily constitute the prior art. 
     Large-size liquid crystal display panels mostly adopt negative VA (Vertical Alignment) liquid crystal technology or IPS (In-Panel Switching) liquid crystal technology. Compared with IPS liquid crystal technology, VA liquid crystal technology has advantages of higher production efficiency and lower manufacturing cost, but it has obvious defects in optical properties. For example, when large-size display panels need to be presented at a larger viewing angle, VA liquid crystal display panels generally have a color shift phenomenon. 
     At present, the way to ameliorate color shift is to give different driving voltages in time sequence to a same sub-pixel or give different driving voltages to adjacent sub-pixels in the display array. However, considering that a same transmission data line is used to drive a same column of sub-pixels, there exists a capacitance-resistance effect between the transmission data line and other electrodes of the pixels. Thus if the transmission data line frequently switches between high and low voltages, the capacitance-resistance effect will distort the high and low voltage signals and affect the display quality of pictures. 
     SUMMARY 
     The main objective of the present application is to provide a driving method for display panel, aiming at improving the display quality of pictures. 
     In order to achieve the above objective, the present application provides a driving method for display panel. The display panel includes a plurality of pixel groups arranged in an array, each of the pixel groups including a first pixel unit, the first pixel unit including at least two first sub-pixels; a first sub-pixel in one of any two adjacent pixel groups is defined as a first target pixel and a first sub-pixel in the other of the two adjacent pixel groups is defined as a second target pixel; the driving method of the display panel includes the following steps: 
     acquiring first initial driving data corresponding to a first target pixel, acquiring second initial driving data corresponding to a second target pixel; 
     determining corresponding first high voltage data according to the first initial driving data, and determining corresponding first low voltage data according to the second initial driving data; 
     determining first target high voltage driving data corresponding to the first target pixel according to the first high voltage data, and determining first target low voltage driving data corresponding to the second target pixel according to the first low voltage data; and 
     driving the first target pixel with the first target high voltage driving data, and driving the second target pixel with the first target low voltage driving data. 
     According to the driving method for display panel of the embodiments of the present application, in the display array of the display panel, a combination of at least two sub-pixels forms a pixel unit, adjacent pixel units are driven by a target high voltage driving data larger than a initial driving data and a target low voltage driving data smaller than a initial driving data respectively. When a row or a column in which the at least two sub-pixels are located is driven using the same data line, since the sub-pixels in a pixel unit are all of high voltage or low voltage, the high and low voltages on the data line do not need to be frequently switched in units of sub-pixels, but are switched in units of pixel units. Therefore, it is beneficial to lighten the color shift while avoid signal distortion caused by capacitance-resistance effect and improve the display quality of pictures.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     It should be understood that the specific embodiments described herein are intended to explain the application only and are not intended to limit the application. 
     That main solution of the embodiments of the present application is that, in a display panel, the display panel includes a plurality of pixel groups  01  arranged in an array, each of the pixel groups  01  including a first pixel unit, the first pixel unit including at least two first sub-pixels; a first sub-pixel in one of any two adjacent pixel groups  01  being defined as a first target pixel  11  and a first sub-pixel in the other of any two adjacent pixel groups  01  being defined as a second target pixel  12 . Based on the above settings, a driving method for display panel includes the following steps: acquiring first initial driving data corresponding to the first target pixel  11  and acquiring second initial driving data corresponding to the second target pixel  12 ; determining first high voltage data corresponding to the first initial driving data, and determining first low voltage data corresponding to the second initial driving data; determining first target high voltage driving data corresponding to the first target pixel  11  according to the first high voltage data, and determining first target low voltage driving data corresponding to the second target pixel  12  according to the first low voltage data; and driving the first target pixel  11  with the first target high voltage driving data, and driving the second target pixel  12  with the first target low voltage driving data. Since a same transmission data line is used to drive a same column of sub-pixels, and there exists a capacitance-resistance effect between the transmission data line and other electrodes of pixels, the capacitance-resistance effect will distort high and low voltage signals and affect a display quality of pictures if the transmission data line frequently switches between the high and low voltages. The present application provides a solution, which is beneficial to avoid signal distortion caused by the capacitance-resistance effect and improve the display quality of pictures. 
     An embodiment of the present application provides a driving method for display panel, which is applied to drive a display panel. The display panel can specifically include a liquid crystal display panel, in particular a TN (twisted nematic) liquid crystal display panel, an OCB (optically compensated birefringence) liquid crystal display panel, a VA type liquid crystal display panel, or the like. The display panel includes pixel groups  01  arranged in an array. The pixel groups  01  include a first pixel unit  10 , and the first pixel unit  10  includes at least two first sub-pixels. Each first sub-pixel in one of each two adjacent pixel groups  01  is defined as a first target pixel  11 , and each first sub-pixel in the other of the two adjacent pixel groups  01  is defined as a second target pixel  12 . 
     In a display array  1  of the liquid crystal display panel, a plurality of sub-pixels are arranged in an array, and each sub-pixel is connected to a gate data line and a source data line. The sub-pixels of a row are connected to a same gate data line and the sub-pixels of a column are connected to a same source data line. The sub-pixels of each row receive a gate driving signal input by a gate driver through the gate data line to control thin film transistors of the sub-pixels to be turned on or off. When a thin film transistor is turned on, a sub-pixel receives a source driving signal input by the source driver through the source data line. A voltage difference between the source driving signal and a common voltage charges a capacitor, and the voltage cross the capacitor deflects the liquid crystal molecules in the capacitor, so that an amount of light from a backlight corresponding to a deflection degree of the liquid crystal molecules is transmitted by the liquid crystal molecules, thus presenting the sub-pixel at a corresponding brightness. 
     Based on the above settings, referring to  FIG. 1 , the display array  1  of the display panel of the present embodiment includes the pixel groups  01 . Each pixel group  01  includes a first pixel unit  10 , and the pixel groups  01  arranged in an array form the display array  1  of the display panel. Specifically, since at the current sub-pixels of a same column are generally driven by a same source data line, the first pixel unit  10  can include at least two first sub-pixels arranged along a column direction. The first sub-pixel may specifically be a red sub-pixel, a green sub-pixel, a blue sub-pixel, or the like. 
     Referring to  FIG. 2 , a driving method for display panel includes the following steps: 
     Step S 10 , acquiring first initial driving data corresponding to a first target pixel, and acquiring second initial driving data corresponding to a second target pixel. 
     The first initial driving data is a preset driving voltage determined according to a gray scale to be displayed by the first target pixel. Different gray scales are correspondingly set with different preset driving voltages. Specifically, the gray scale corresponding to each first target pixel in image data of a current image frame can be obtained, and the corresponding first initial driving data can be determined according to the gray scale of each first target pixel. 
     The second initial driving data is a preset driving voltage determined according to a gray scale to be displayed by the second target pixel. Different gray scales are correspondingly set with different preset driving voltages. Specifically, the gray scale corresponding to each second target pixel in the image data of the current image frame can be obtained, and the corresponding second initial driving data can be determined according to the gray scale of each second target pixel. 
     Step S 20 , determining a corresponding first high voltage data according to the first initial driving data, and determining a corresponding first low voltage data according to the second initial driving data. 
     The first high voltage data of each first target pixel  11  is greater than the first initial driving data corresponding to the first target pixel  11 , and the first low voltage data of the second target pixel  12  is less than the second initial driving data corresponding to the second target pixel  12 . 
     Specifically, the first initial driving data can be increased by a preset voltage to obtain the first high voltage data, and the second initial driving data can be decreased by a preset voltage to obtain the first low voltage data. Here, the preset voltage increased corresponding to the first initial driving data can be defined as a first preset amplitude, and the preset voltage decreased corresponding to the second initial driving data can be defined as a second preset amplitude. The preset voltage increased and the preset voltage decreased can be determined according to a specific gray scale of each first sub-pixel. The first sub-pixels of different gray scales may correspond to different preset voltages increased and different preset voltages decreased. Therefore, a first preset amplitude of a first sub-pixel which is taken as the first target pixel can be determined according to the gray scale of the first target pixel, and a second preset amplitude of a first sub-pixel which is taken as the second target pixel can be determined according to the gray scale of the second target pixel. 
     Step S 30 , determining first target high voltage driving data corresponding to the first target pixel  11  according to the first high voltage data, and determining first target low voltage driving data corresponding to the second target pixel  12  according to the first low voltage data. 
     Two adjacent first pixel units  10  are defined to include a first unit and a second unit, each of the first sub-pixels in the first unit being the first target pixel  11  and each of the first sub-pixels in the second unit being the second target pixel  12 . 
     The first target high voltage driving data is the driving voltage of the first target pixel  11 , and each first target pixel has a corresponding first target high voltage driving data. The first target low voltage driving data is the driving voltage of the second target pixel  12 , and each second target pixel has a corresponding first target low voltage driving data. 
     The first target high voltage driving data corresponding to each first target pixel  11  can be determined according to the first high voltage data corresponding to the first target pixel  11 . The first high voltage data can be directly taken as the first target high voltage driving data to drive the first target pixel  11 , or the first target high voltage driving data can be calculated according to the first high voltage data and a compensation voltage, and the obtained first target high voltage driving data is used to drive the first target pixel  11 . The first target low voltage driving data corresponding to each second target pixel  12  can be determined based on the first low voltage data corresponding to the second target pixel  12 . The first low voltage data can be directly taken as the first target low voltage driving data to drive the second target pixel  12 , or the first target low voltage driving data can be calculated according to the first low voltage data and a compensation voltage, and the obtained first target low voltage driving data is used to drive the second target pixel  12 . 
     Step S 40 , adopting the first target high voltage driving data to drive the first target pixel  11 , and adopting the first target low voltage driving data to drive the second target pixel  12 . 
     A schematic diagram of a driving voltage distribution of the sub-pixels in the display array  1  can make reference to  FIG. 1 . 
     According to the driving method for display panel of the embodiments of the present application, in the display array of the display panel, a combination of at least two sub-pixels forms a pixel unit, adjacent pixel units are driven by a target high voltage driving data larger than the initial driving data and a target low voltage driving data smaller than the initial driving data respectively. When a row or a column in which the at least two sub-pixels are located is driven using the same data line, since the sub-pixels in a pixel unit are all of high voltage or low voltage, the high and low voltages on the data line do not need to be frequently switched in units of sub-pixels, but are switched in units of pixel units. Therefore, it is beneficial to lighten the color shift while avoid signal distortion caused by capacitance-resistance effect and improve the display quality of pictures. 
     Further, referring to  FIG. 3 , defining a second target pixel  12  adjacent to the first target pixel  11  as a first compensation pixel, the step of determining first target high voltage driving data corresponding to the first target pixel  11  according to the first high voltage data includes: 
     Step S 31 , determining first compensation pixels corresponding to the first target pixel  11 . 
     All the first compensation pixels (such as the sub-pixel corresponding to L 33 , the sub-pixel corresponding to L 44  and the sub-pixel corresponding to L 35  in  FIG. 1 ) adjacent to the first target pixel  11  (such as the sub-pixel corresponding to H 34  in  FIG. 1 ) are determined. 
     Step S 32 , determining corresponding first compensation high voltage data according to second initial driving data of the first compensation pixels. 
     Since each second target pixel  12  has corresponding second initial driving data, the first compensation high voltage data corresponding to each first compensation pixel can be determined based on the second initial driving data. The first compensation high voltage data of each first compensation pixel is greater than the second initial driving data corresponding to the first compensation pixel. Specifically, the second initial driving data can be increased by a preset voltage corresponding to the sub-pixel to obtain the first compensation high voltage data. The preset voltage increased corresponding to the first compensation pixel can be defined as a third preset amplitude. 
     Step S 33 , determining the first target high voltage driving data according to the first high voltage data and the first compensation high voltage data. 
     Each first compensation pixel corresponds to first compensation high voltage data. The first target high voltage driving data can be obtained according to the first high voltage data of the first target pixel  11  and the first compensation high voltage data of the first compensation pixels. Specifically, a sum of the first high voltage data of the first target pixel  11  and the first compensation high voltage data corresponding to all the first compensation pixels adjacent to the first target pixel  11  can be taken as the first target high voltage driving data, or, a sum of the first high voltage data of the first target pixel  11  and the first compensation high voltage data corresponding to part of the first compensation pixels adjacent to the first target pixel  11  can be taken as the first target high voltage driving data. Since the second target pixel  12  itself displays the first target low voltage data, part or all of the first compensation high voltage data originally to be displayed by the second target pixels  12  adjacent to the first target pixel  11  are re-assigned to the first target pixel  11  as the compensation voltage of the first target pixel  11 , the first target high voltage driving data displayed by the first target pixel  11  has characteristics to be displayed by its own first high voltage data and the first compensation high voltage data from its adjacent second target pixels  12 , thereby lightening color shift while ensuring a resolution of the picture. 
     In addition, in order to further improve the resolution of the picture, step S 33  can include: 
     Step S 331 , acquiring a first preset weight corresponding to the first compensation pixel. 
     According to different resolution requirements, different first compensation pixels are correspondingly set with same or different first preset weights. Specifically, a resolution of a current picture can be obtained, and a value of the first preset weight corresponding to each first compensation pixel can be determined according to the obtained resolution. 
     Step S 322 , determining the first target high voltage driving data according to the first high voltage data, the first compensation high voltage data and the first preset weight. 
     The first compensation high voltage data of each of the first compensation pixels adjacent to the first target pixel  11  is assigned to the first target pixel  11  by weights, the first target high voltage driving data corresponding to the first target pixel  11  is calculated according to the first compensation high voltage data assigned to the first target pixel  11  and the first high voltage data of the first target pixel  11 . 
     Taking determining the first target high voltage data of the sub-pixel corresponding to H 34  as an example, the first high voltage data of the sub-pixel corresponding to H 34  is H′ 34 , the first compensation pixels of the sub-pixel corresponding to H 34  are the sub-pixels respectively corresponding to L 33 , L 44 , and L 35 . If the first compensation high voltage data of the sub-pixel corresponding to L 33  is H 33 , the first compensation high voltage data of the sub-pixel corresponding to L 44  is H 44 , the first compensation high voltage data of the sub-pixel corresponding to L 35  is H 35 , and the first preset weight corresponding to each of the first compensation pixels is ⅓, then H 34 =(H 34 +⅓*(H 33 +H 44 +H 35 ))/2. 
     Through the above method, a presenting effect achieved by driving the first target pixel  11  with the first target high voltage is equivalent to a displaying effect achieved by driving each sub-pixel with the initial driving data (the first initial driving data and the second initial driving data), thereby ensuring the resolution of picture while ensuring view angle compensation. 
     Further, referring to  FIG. 4 , defining a first target pixel  11  adjacent to the second target pixel  12  as a second compensation pixel, the step of determining first target low voltage driving data corresponding to the second target pixel  12  according to the first low voltage data includes: 
     Step S 34 , determining second compensation pixels corresponding to the second target pixel  12 . 
     All second compensation pixels (such as the sub-pixel corresponding to H 43 , the sub-pixel corresponding to H 34  and the sub-pixel corresponding to H 45  in  FIG. 1 ) adjacent to the second target pixel  12  (such as the sub-pixel corresponding to L 44  in  FIG. 1 ) are determined. 
     Step S 35 , determining corresponding first compensation low voltage data according to first initial driving data of the second compensation pixels. 
     Since each of the first target pixels  11  has corresponding first initial driving data, the first compensation low voltage data corresponding to each of the second compensation pixels can be determined based on the first initial driving data. The first compensation low voltage data of each second compensation pixel is less than the first initial driving data corresponding to the second compensation pixel. Specifically, the first initial driving data can be decreased a preset voltage corresponding to the sub-pixel to obtain the first compensation low voltage data. The preset voltage decreased corresponding to the second compensation pixel can be defined as a fourth preset amplitude. 
     Step S 36 , determining the first target low voltage driving data according to the first low voltage data and the first compensation low voltage data. 
     Each second compensation pixel corresponds to first compensation low voltage data. The first target low voltage driving data can be obtained according to the first low voltage data of the second target pixel  12  and the first compensation low voltage data of the second compensation pixels. Specifically, a sum of the first low voltage data of the second target pixel  12  and the first compensation low voltage data corresponding to all the second compensation pixels adjacent to the second target pixel  12  can be taken as the first target low voltage driving data, or a sum of the first low voltage data of the second target pixel  12  and the first compensation low voltage data corresponding to part of the second compensation pixels adjacent to the second target pixel  12  can be taken as the first target low voltage driving data. Since the first target pixel  11  itself displays the first target high voltage data, part or all of the first compensation low voltage data which should be displayed by the first target pixels  11  adjacent to the second target pixel  12  are re-assigned to the second target pixel  12  as the compensation voltage of the second target pixel  12 , the first target low voltage driving data displayed by the second target pixel  12  has characteristics to be displayed by its own first low voltage data and the first compensation low voltage data from its adjacent second target pixels  12 , thereby lightening color shift while ensuring the resolution of the picture. 
     Among them, the steps S 31 , S 32 , S 33 , S 34 , S 35  and S 36  are simultaneously executed, and the first target pixel  11  is compensated by the first compensation high voltage data and the second target pixel  12  is compensated by the first compensation low voltage data, which is beneficial to improve the overall resolution of the displayed picture and make the displayed picture present a complete image quality. 
     In addition, in order to further improve the resolution of the picture, step S 36  can include: 
     Step S 361 , acquiring second preset weights corresponding to the second compensation pixels. 
     According to different resolution requirements, different second compensation pixels are correspondingly set with a same second preset weight or with different second preset weights. Specifically, the resolution of the current displayed picture can be obtained, and a value of the second preset weight corresponding to each second compensation pixel can be determined according to the obtained resolution. 
     Step S 362 , determining the first target low voltage driving data according to the first low voltage data, the first compensation low voltage data and the second preset weights. 
     The first compensation low voltage data of each of the second compensation pixels adjacent to the second target pixel  12  is re-assigned to the second target pixel  12  according to the corresponding second preset weight. The first target low voltage driving data corresponding to the second target pixel  12  is calculated according to the first compensation low voltage data re-assigned to the second target pixel  12  and the first low voltage data of the second target pixel  12 . 
     Taking determining the first target low voltage data L 44  of the sub-pixel corresponding to L 44  as an example, the first low voltage data of the sub-pixel corresponding to L 44  is L′ 44 , the first compensation pixels of the sub-pixel corresponding to L 44  is the sub-pixels respectively corresponding to H 43 , H 34 , and H 45 , the first compensation low voltage data of the sub-pixel corresponding to H 43  is L 43 , the first compensation low voltage data of the sub-pixel corresponding to H 34  is L 34 , and the first compensation low voltage data of the sub-pixel corresponding to H 45  is L 45 , and the second preset weight corresponding to each second compensation pixel is ⅓, then the first target low voltage data L 44 =(L 44 +⅓*(L 43 +L 34 +L 45 ))/2. 
     Through the above method, a presenting effect achieved by driving the second target pixel  12  with the first target low voltage is equivalent to a displaying effect achieved by driving each sub-pixel with the initial driving data (the first initial driving data and the second initial driving data), thereby ensuring the resolution of picture while ensuring view angle compensation. 
     Further, referring to  FIG. 5 , each pixel group  01  further includes a second pixel unit  20  and a third pixel unit  30 , the second pixel unit  20  including at least two second sub-pixels, the third pixel unit  30  including at least two third sub-pixels. The first pixel unit  10 , the second pixel unit  20  and the third pixel unit  30  in each pixel group  01  are sequentially arranged along a row direction. Each second sub-pixel in one of any two adjacent pixel groups  01  is defined as a third target pixel  21  and each second sub-pixel in the other of the two adjacent pixel groups  01  is defined as a fourth target pixel  22 . Each third sub-pixel in one of any two adjacent pixel groups  01  is defined as a fifth target pixel  31 , and each third sub-pixel in the other of the two adjacent pixel groups  01  is defined as the sixth target pixel  32 . 
     The pixel group  01  includes the second pixel unit  20  and the third pixel unit  30  in addition to the first pixel unit  10 . In one pixel group  01 , that first pixel unit  10 , the second pixel unit  20  and the third pixel unit  30  are sequentially arrange in the row direction. A plurality of pixel groups  01  composed of the first pixel unit  10 , the second pixel unit  20 , and the third pixel unit  30  are arranged in an array to form the display array  1 . In particular, since currently sub-pixels of a same column are generally driven by a same source data line, the second pixel unit  20  can include at least two second sub-pixels arranged in the column direction and the third pixel unit  30  can includes at least two third sub-pixels arranged in the column direction. The first sub-pixel, the second sub-pixel and the third sub-pixel can be a red sub-pixel, a green sub-pixel, a blue sub-pixel, or the like respectively, so as to realize multi-color display of the picture. 
     Referring to  FIG. 6 , the driving method of the display panel further includes the following steps: 
     Step S 50 , acquiring third initial driving data corresponding to a third target pixel  21 , acquiring fourth initial driving data corresponding to a fourth target pixel  22 , acquiring fifth initial driving data corresponding to a fifth target pixel  31 , and acquiring sixth initial driving data corresponding to a sixth target pixel  32 ; 
     Step S 60 , determining corresponding second high voltage data according to the third initial driving data, determining corresponding second low voltage data according to the fourth initial driving data, determining corresponding third high voltage data according to the fifth initial driving data, and determining corresponding third low voltage data according to the sixth initial driving data; 
     Step S 70 , determining second target high voltage driving data corresponding to the third target pixel  21  according to the second high voltage data, determining second target low voltage driving data corresponding to the fourth target pixel  22  according to the second low voltage data, determining a third target high voltage driving data corresponding to the fifth target pixel  31  according to the third high voltage data, and determining a third target low voltage driving data corresponding to the sixth target pixel  32  according to the third low voltage data; 
     Step S 80 , driving the third target pixel  21  with the second target high voltage driving data, driving the fourth target pixel  22  with the second target low voltage driving data, driving the fifth target pixel  31  with the third target high voltage driving data, and driving the sixth target pixel  32  with the third target low voltage driving data. 
     Defining a fourth target pixel  22  adjacent to a third target pixel  21  as a third compensation pixel, the step of determining second target high voltage driving data corresponding to the third target pixel  21  according to the second high voltage data includes: determining third compensation pixels corresponding to the third target pixel  21 ; determining corresponding second compensation high voltage data according to fourth initial driving data of the third compensation pixels; and determining the second target high voltage driving data based on the second high voltage data and the second compensation high voltage data. Defining a third target pixel  21  adjacent to the fourth target pixel  22  as a fourth compensation pixel, the step of determining second target low voltage driving data corresponding to the fourth target pixel  22  according to the second low voltage data includes: determining fourth compensation pixels corresponding to the fourth target pixel  22 ; determining corresponding second compensation low voltage data according to third initial driving data of the fourth compensation pixels; and determining the second target low voltage driving data based on the second low voltage data and the second compensation low voltage data. Defining a sixth target pixel  32  adjacent to the fifth target pixel  31  as a fifth compensation pixel, the step of determining third target high voltage driving data corresponding to the fifth target pixel  31  according to the third high voltage data includes: determining fifth compensation pixels corresponding to the fifth target pixel  31 ; determining corresponding third compensation high voltage data according to sixth initial driving data of the fifth compensation pixels; and determining the third target high voltage driving data based on the third high voltage data and the third compensation high voltage data. Defining a fifth target pixel  31  adjacent to the sixth target pixel  32  as a sixth compensation pixel, the step of determining third target low voltage driving data corresponding to the sixth target pixel  32  according to the third low voltage data includes: determining sixth compensation pixels corresponding to the sixth target pixel  32 ; determining corresponding third compensation low voltage data according to fifth initial driving data of the sixth compensation pixels; and determining the third target low voltage driving data based on the third low voltage data and the third compensation low voltage data. 
     The determination of second target high voltage driving data corresponding to the third target pixel  21  in the second pixel unit  20 , and the determination of third target high voltage driving data corresponding to the fifth target pixel  31  in the third pixel unit  30  can make reference to the determination of the first target high voltage driving data corresponding to the first target pixel  11  in the first pixel unit  10  in the above embodiments, and will not be described here.
