CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a CIP of U.S. patent application Ser. No. 17/035,946 filed Sep. 29, 2020 entitled “METHOD FOR DRIVING DISPLAY DEVICE AND DRIVER,” which is based on, and claims the benefit of and priority to, Chinese Patent Application No. 202010103814.3 filed on Feb. 20, 2020, the contents of which are incorporated reference in their entirety herein. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to display technologies and, in particular, to a method for driving a display device and a driver. 
     BACKGROUND 
     OLED display devices (e.g., organic light emitting displays and organic electroluminescent devices) have advantages of high transmittance, super thinness, high-definition, high brightness, high contrast, fast response, low energy consumption, flexible display, etc., and thus, they are widely applied. 
     OLED display devices can use a GRGB sub-pixel arrangement instead of Real RGB sub-pixel arrangement. For example, sub-pixels can be arranged in a Diamond pixel arrangement and SPR (Sub-Pixel Render, a sub-pixel borrowing algorithm) can be used to display images. However, when displaying single pixel dot images or single pixel line images, the SPR algorithm cannot achieve desired effects. 
     The above information disclosed in the background section is only used to enhance the understanding of the background of the present disclosure, so it may include information that does not constitute prior art known to those of ordinary skill in the art.

In this way, the red sub-screen pixel  102   a  display 100% of the red part required by the image pixel, the blue sub-screen pixel  103   a  displays 100% of the blue part required by the image pixel, and each of the green sub-screen pixels  101   a  displays 50% of the green part required by the image pixel. 
       FIG.  4    is a display effect diagram when a display device displays one image pixel and several adjacent image pixels in the same column according to the conventional SPR algorithm. Referring to  FIG.  4   , a group of sub-screen pixels  201   b  can be lit to display one image pixel; a group of sub-screen pixels  202   c  can be lit to display several adjacent image pixels in the same column. Any image pixel can be displayed by one red sub-screen pixel  102   a , one blue sub-screen pixel  103   a  and two green sub-screen pixels  101   a , and the light-emitting brightness of one green sub-screen pixel  101   a  is 50% of the required green brightness. 
     However, when displaying a single-pixel dot pattern or a single-pixel line pattern, for example when displaying fonts and lines, the green sub-screen pixels are located on one side of each screen pixel, and thus the single-pixel dot pattern or the single-pixel line pattern displayed by the display device may become greener on the one side of the single-pixel dot pattern or the single-pixel line pattern. On the other side, because the red sub-screen pixel generally have higher luminous efficiency than the blue sub-screen pixel, the other side of the single-pixel dot pattern or the single-pixel line pattern may become more red in contrast to the greener one side of the ingle-pixel dot pattern or the single-pixel line pattern. In addition, when the SPR algorithm performs pixel borrowing, the line displayed for the single-pixel line pattern will be thicker, which will affect the display effect. In addition, due to the high luminous efficiency of the green sub-screen pixels, the aperture ratio of the green sub-screen pixels is smaller than that of the red sub-screen pixels and blue sub-screen pixels, and the uniformity or evenness of the arrangement of the green sub-screen pixels is often not as high as the red sub-screen pixels and blue sub-screen pixels. Thus, when a single pixel line pattern is displayed using the SPR algorithm, the displayed image often has noticeable jaggedness. 
     In order to improve the display effect of the display device, the present disclosure provides a method for driving the display device. As shown in  FIG.  5   , the display device includes a plurality of screen pixels  100  arranged in an array. The screen pixels  100  include a plurality of first screen pixels  110  and a plurality of second screen pixels  120 . Each of the first screen pixels  110  includes one first sub-screen pixel  101  and one second sub-screen pixel  102 . Each of the second screen pixels  120  includes one first sub-screen pixel  101  and one third sub-screen pixel  103 . Along the row direction A, in any row of screen pixels  100 , the first screen pixels  110  and the second screen pixels  120  are alternately arranged, the first sub-screen pixels  101  are arranged along a straight line, and a second sub-screen pixel  102  or a third sub-screen pixel  103  is arranged between any two adjacent first sub-screens pixels  101 . Along the column direction B, in any column of screen pixels  100 , the first screen pixels  110  and the second screen pixels  120  are alternately arranged, and the sub-screen pixels  101  are arranged along a straight line. 
     As shown in  FIG.  6   , the method for driving the display device includes the following steps: 
     In step S 110 , image data is obtained. The image data includes color parameters of image pixels corresponding to the plurality of screen pixels  100  one to one. 
     In step S 120 , whether the image pixels are detail pixels is determined according to the image data. A detail pixel refers to an image pixel for displaying a single pixel dot pattern or a single pixel line pattern. 
     In step S 130 , a plurality of screen pixel groups are determined. As shown in  FIG.  7   , any one of the screen pixel groups  200  includes two of the screen pixels  100  adjacently arranged in a same row, and a screen pixel  100  corresponding to each of the detail pixels is in the screen pixel group  200 . 
     In step S 110 , the screen pixels  100  are driven for display. As shown in  FIG.  7   , a first sub-screen pixel  101  located between a second sub-screen pixel  102  and a third sub-screen pixel  103  in any one of the screen pixel groups  200  is used for emitting light, and the other first sub-screen pixel  101  in the any one of the screen pixel groups  200  does not emit light. 
     In the method for driving the display device according to embodiments of the present disclosure, detail pixels used for presenting a single pixel dot pattern or a single pixel line pattern are determined first, then a plurality of screen pixel groups  200  are determined according to the detail pixels, and the screen pixel groups  200  are used for displaying the detail pixels. In each of the screen pixel groups  200 , a first sub-screen pixel  101  located between a second sub-screen pixel  102  and a third sub-screen pixel  103  is used to emit light, and the other first sub-screen pixel  101  in the screen pixel group  200  does not emit light. In this way, embodiments of the present disclosure can avoid color shift when the single pixel dot pattern or the single pixel line pattern is displayed caused by arranging the first sub-screen pixel  101  at one side of the screen pixel group  200 . Also, because the first sub-screen pixel  101  located between the second sub-screen pixel  102  and the third sub-screen pixel  103  is used for 100% light emission while the other first sub-screen pixel  101  does not emit light, jaggedness resulted from uneven arrangement of the first sub-screen pixels  101  can be reduced, thereby improving the definition and fitness of the displayed single-pixel pattern or single-pixel line pattern. 
       FIG.  8    is a display effect diagram of displaying one image pixel and several adjacent image pixels in the same column according to the method for driving the display device according to embodiments of the present disclosure. A screen pixel group  200   a  is used to display an image pixel. As shown in  FIG.  8   , only the first sub-screen pixel  101  arranged between the second sub-screen pixel  102  and the third sub-screen pixel  103  in the screen pixel group  200   a  emits light, the other first sub-screen pixel  101  does not emit light, and the first sub-screen pixel  101  that emits light is used to emit 100% of the required light instead of 50%. A set of adjacent screen pixel groups  200   b  in the same column are used to display several adjacent image pixels in the same column. As shown in  FIG.  8   , in the set of screen pixel groups  200   b , only the first sub-screen pixels  101  between second sub-screen pixels  102  and the third sub-screen pixels  103  emit light. 
       FIG.  9    is a diagram showing display effects when a Chinese character “ ” is displayed using the existing SPR algorithm. As shown in  FIG.  9   , the displayed Chinese character “ ” is not clear, and looks blurry. Also, the left side of the displayed Chinese character “ ” is greener and the right side of the displayed Chinese character “ ” is more red ( FIG.  9    is a grayscale picture, the color effect of the picture cannot be effectively displayed).  FIG.  10    is a diagram showing display effects when the display device displays the Chinese character “ ” using the driving method of the display device according to embodiments of the present disclosure. As shown in  FIG.  10   , the displayed Chinese character “ ” is clear, and there is no problem of color shift on the left and right sides. Therefore, the method for driving the display device according to embodiments of the present disclosure can significantly increase the clarity of displayed characters. 
       FIG.  11    is a diagram showing display effects when horizontal lines are displayed using the existing SPR algorithm. Each of  301   a ,  302   a , and  303   a  includes multiple lines. The difference between  301   a ,  302   a , and  303   a  lies in that the distances between adjacent lines are different. As can be seen from  301   a ,  302   a , and  303   a , no matter how the distance between adjacent lines changes, the lines show noticeable jaggedness. The reference sign  304   a  shows the display effect when only the red sub-screen pixels are lit, the reference sign  306   a  shows the display effect when only the blue sub-screen pixels are lit, and the reference sign  305   a  shows the display effect when only the green sub-screen pixels are lit. As can be seen from  305   a , when only green sub-screen pixels are lit, the pattern presents a noticeable jaggedness.  FIG.  12    is a diagram showing display effects when horizontal lines are displayed by the display device using the driving method provided by embodiments of the present disclosure. Each of  301 ,  302 , and  303  includes multiple lines, and the difference between  301 ,  302 , and  303  lies in that the distances between adjacent lines are different. As can be seen from  301 ,  302  and  303 , no matter how the distance between adjacent lines changes, the lines are smooth and delicate, and there is no obvious jaggedness. The reference sign  304  shows the display effect when only the second sub-screen pixels are lit, the reference sign  306  shows the display effect when only the third sub-screen pixels are lit, and the reference sign  305  shows the display effect when only the first sub-screen pixels are lit. It can be understood that since only one first sub-screen pixel in any screen pixel group emits light, and the other first sub-screen pixel does not emit light, only one of any two adjacent first sub-screen pixels set in the same row in  305  emits light. As can be seen from  305 , when only the first sub-screen pixels are lit, the pattern is smooth and delicate, and there is no obvious jaggedness. Therefore, the method for driving the display device according to embodiments of the present disclosure can reduce the jaggedness generated when the first sub-screen pixels in the same row are lit, thereby improving the fineness of the horizontal lines. 
       FIG.  13    is a diagram showing display effects when a line pattern is displayed using the existing SPR algorithm.  FIG.  14    is a diagram showing display effects when the same line pattern is displayed by the display device using the driving method provided by embodiments of the present disclosure. Comparing  FIG.  13    and  FIG.  14   , it can be seen that the lines in  FIG.  13    are rougher and the lines in  FIG.  14    are more delicate. Therefore, the method for driving the display device according to embodiments of the present disclosure can improve the fineness of lines. 
     Hereinafter, the steps, principles, and effects of the method for driving the display device according to embodiments of the present disclosure will be described in detail. 
     The display device according to embodiments of the present disclosure may be an RGB display device. That is, the three types of sub-screen pixels may be red sub-screen pixels, green sub-screen pixels, and blue sub-screen pixels. In an embodiment of the present disclosure, the first sub-screen pixels  101  may be green sub-screen pixels, the second sub-screen pixels  102  may be red sub-screen pixels, and the third sub-screen pixels  103  may be blue sub-screen pixels. In any row of screen pixels  100 , the second sub-screen pixels  102  and the third sub-screen pixels  103  can be alternately arranged along the same line; in any column of screen pixels  100 , the second sub-screen pixels  102  and the third sub-screen pixels  103  may be alternately arranged along a straight line. 
     When displaying non-detail pixels, the display device according to embodiments of the present disclosure can display pictures or images using the SPR algorithm. When an image pixel needs to be displayed, the screen pixel  100  corresponding to the image pixel can borrow a sub-pixel from other screen pixels  100  arranged adjacently in the same row or arranged adjacently in the same column to display the image pixel. It is understandable that sub-pixels in the screen pixel  100  can also be borrowed by other screen pixels  100  to display other image pixels. 
     In step S 110 , the color parameters of the image pixels corresponding to the screen pixels  100  one to one are obtained. A color parameter of any one of the pixel images includes a first color grayscale value, a second color grayscale value, and a third color grayscale value. 
     According to embodiments, the first color can be close to the color that the first sub-screen pixels  101  can display, the second color can be close to the color that the second sub-screen pixels  102  can display, and the third color can be close to the color that the third sub-screen pixels  103  can display. For example, the first color can be green, and when the first sub-screen pixels  101  are lit, the first sub-screen pixels  101  can emit green light. The second color can be red, and when the second sub-screen pixels  102  are lit, the second sub-screen pixels  102  can emit red light. The third color may be blue, and when the third sub-screen pixels  103  are lit, the third sub-screen pixels  103  can emit blue light. 
     According to embodiments, the image pixels in the image data are in a one-to-one correspondence with the screen pixels  100 . This means that any one image pixel corresponds to a screen pixel  100  having the same row and column coordinates as the one image pixel. For example, an image pixel A(i, j) and a screen pixel  100 P(i, j) are an image pixel and a screen pixel  100  which correspond to each other. The image pixel A(i, j) is an image pixel in i-th row and j-th column. The screen pixel  100 P(i, j) is a screen pixel  100  in i-th row and j-th column. 
     The driver for driving the display device may be provided with an image data obtaining circuit for obtaining image data. In an embodiment of the present disclosure, the image data obtaining circuit may include a data port and a data memory, the data port is used to receive externally input image data, and the data memory may receive and store the image data received by the data port directly or through a controller. Alternatively, the image data obtaining circuit may be implemented by other integrated ICs, and/or memories. 
     In an embodiment of the present disclosure, the image data may be in a BMP format. 
     In step S 120 , whether the image pixels are detail pixels may be determined according to the image data. A detail pixel is an image pixel used to display a single pixel dot pattern or a single pixel line pattern. 
     In embodiments of the present disclosure, the single-pixel dot pattern is a dot pattern, which has only one image pixel, and the pattern has a significant color difference from the surrounding patterns. The single-pixel line pattern is a line, and the width of the line is equal to one image pixel, and the pattern has a significant color difference from the surrounding patterns. Among the image pixels, the image pixels used to display the single pixel dot pattern or the single pixel line pattern are the detail pixels as referred to in embodiments of the present disclosure. When the SPR algorithm in related arts is used to display a single-pixel dot pattern or a single-pixel line pattern, the displayed pattern may have problems such as blurred patterns, jagged patterns, and color shifts in the row direction of the patterns. 
     Step S 120  can be implemented by the following method: 
     In step S 210 , for any three adjacently arranged image pixels among the image pixels in each row, a color parameter of a middle image pixel which is in the middle of the three adjacently arranged image pixels is compared with color parameters of other two image pixels of the three adjacently arranged image pixels. 
     In step S 220 , if at least one of differences between the first color grayscale value, the second color grayscale value and the third color grayscale value of the middle image pixel and the first color grayscale value, the second color grayscale value and the third color grayscale value of a preceding image pixel satisfies a preset threshold, and at least one of differences between the first color grayscale value, the second color grayscale value and the third color grayscale value of the middle image pixel and the first color grayscale value, the second color grayscale value and the third color grayscale value of a following image pixel satisfies a preset threshold, the middle image pixel is determined as a detail pixel. 
     In step S 230 , for any three adjacently arranged image pixels among the image pixels in each column, a color parameter of a middle image pixel which is in the middle of the three adjacently arranged image pixels is compared with color parameters of other two image pixels of the three adjacently arranged image pixels. 
     In step S 240 , if at least one of differences between the first color grayscale value, the second color grayscale value and the third color grayscale value of the middle image pixel and the first color grayscale value, the second color grayscale value and the third color grayscale value of an upper image pixel satisfies a preset threshold, and at least one of differences between the first color grayscale value, the second color grayscale value and the third color grayscale value of the middle image pixel and the first color grayscale value, the second color grayscale value and the third color grayscale value of a lower image pixel satisfies a preset threshold, the middle image pixel is determined as a detail pixel.

     G 3 (i, j+2) is the third color grayscale value of the image pixel A(i, j+2). 
     According to embodiments, in step S 220 , if at least one of |G 1 (i, j+1)−G 1 (i, j)|&gt;G 1   ref , |G 2 (i, j+1)−G 2 (i, j)|&gt;G 2   ref  and |G 3 (i, j+1)−G 3 (i, j)|&gt;G 3   ref  is satisfied, and at least one of |G 1 (i, j+1)−G 1 (i, j+2)|&gt;G 1   ref , |G 2 (i, j+1)−G 2 (i, j+2)|&gt;G 2   ref  and |G 3 (i, j+1)−G 3 (i, j+2)|&gt;G 3   ref  is satisfied, the image pixel A(i, j+1) is determined as the detail pixel;

     wherein:

     G 3 (i+2, j) is the third color grayscale value of the image pixel A(i+2, j). 
     According to embodiments, in step S 240 , if at least one of |G 1 (i+1, j)−G 1 (i, j)|&gt;G 1   ref , |G 2 (i+1, j)−G 2 (i, j)|&gt;G 2   ref  and |G 3 (i+1, j)−G 3 (i, j)|&gt;G 3   ref  is satisfied, and at least one of |G 1 (i+1, j)−G 1 (i+2, j)|&gt;G 1   ref , |G 2 (i+1, j)−G 2 (i+2, j)|&gt;G 2   ref  and |G 3 (i+1, j)−G 3 (i+2, j)|&gt;G 3   ref  is satisfied, determining that the image pixel A(i+1, j) is the detail pixel;

For example, if the number of grayscales of the image data is 10 bits, the maximum value of any color grayscale of the image pixels is 1023; correspondingly, the first color grayscale threshold, the second color grayscale threshold G 2   ref  and the third color grayscale threshold G 3   ref  may not be less than 512. In another example, if the number of grayscales of the image data is 8 bits, the maximum value of any color grayscale value of the image pixels is 255; correspondingly, the first color grayscale threshold, the second color grayscale threshold G 2   ref  and the third color grayscale threshold G 3   ref  may not be less than 128. 
     According to other embodiments, G 1   ref ≥0.75*G max , G 2   ref ≥0.75*G max , G 3   ref ≥0.75*G max . 
     The driver for driving the display device may be provided with an analysis circuit (Data Path). The analysis circuit can read the image data stored in the data memory directly or through a controller, so as to receive and analyze the image data to determine whether each image pixel is a detail pixel. According to embodiments, the analysis circuit may include a picture detection sub-circuit (IP module in an integrated circuit), and the picture detection sub-circuit is used to determine whether each image pixel is a detail pixel. 
     In step S 130 , screen pixel groups  200  may be determined according to determined detail pixels. Any screen pixel group  200  includes two adjacent screen pixels  100  in the same row, and the screen pixel  100  corresponding to each detail pixel is located in a screen pixel group  200 . 
     For example, when it is determined that the image pixel A(i, j+1) is a detail pixel, the screen pixel  100  corresponding to the image pixel A(i, j+1) is the screen pixel  100 P(i, j+1). In an embodiment of the present disclosure, the screen pixel  100 P(i, j+1) and the screen pixel  100 P(i, j) can be selected to form a screen pixel group  200 B(i, j), which is used as the screen pixel group  200  for displaying the image pixel A(i, j+1). In another embodiment of the present disclosure, the screen pixel  100 P(i, j+1) and the screen pixel  100 P(i, j+2) can be selected to form a screen pixel group  200 B(i, j+1), which is used as the screen pixel group  200  for displaying the image pixel A(i, j+1). 
     For another example, when it is determined that the image pixel A(i, j+1) and the image pixel A(i, j+2) are both detail pixels, the screen pixel  100  corresponding to the image pixel A(i, j+1) is the screen pixel  100 P(i, j+1), and the screen pixel  100  corresponding to the image pixel A(i, j+2) is the screen pixel  100 P(i, j+2). In an embodiment of the present disclosure, the screen pixel  100 P(i, j+1) and the screen pixel  100 P(i, j) can be selected to form a screen pixel group  200 B(i, j) which is used as the screen pixel group  200  for displaying the image pixel A(i, j+1). The screen pixel  100 P(i, j+2) and the screen pixel  100 P(i, j+3) may be selected to form a screen pixel group  200 B(i, j+2) which is used as a screen pixel group  200  for displaying the image pixel A(i, j+2). In this way, two adjacent image pixels in the same row can respectively correspond to two screen pixel groups  200 , and each of the two adjacent image pixels can be displayed by a corresponding screen pixel group  200 . In another embodiment of the present disclosure, the screen pixel  100 P(i, j+1) and the screen pixel  100 P(i, j+2) can be selected to form a screen pixel group  200 B(i, j+1) which is used as the screen pixel group  200  for displaying the image pixel A(i, j+1) and the image pixel A(i, j+2). In this way, two adjacent image pixels in the same row can jointly correspond to the same screen pixel group  200  and be displayed by the same screen pixel group  200 . 
     According to embodiments, the driver for driving the display device may be provided with a mapping circuit, which is used to determine a plurality of screen pixel groups  200 . Any screen pixel group  200  includes two adjacent screen pixels  100  in the same row, and the screen pixel  100  corresponding to each detail pixel is located in the screen pixel group  200 . 
     In step S 140 , screen pixels  100  can be driven for displaying image(s).
