[0064] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0065] Figure 1 A schematic diagram of a pixel structure is shown in FIG. Figure 1 As shown, the pixel structure includes multiple rows of gate lines, multiple columns of data lines that are insulated and intersecting with the multiple rows of gate lines, and multiple pixels arranged between two rows of gate lines. Each pixel is connected to a pixel common voltage (Vcom). In addition, the positive polarity data lines and the negative polarity data lines are arranged in an intersecting manner.

[0066] Figure 2 shows a schematic diagram of lateral crosstalk, such as Figure 2 As shown in the figure, in a black background with white frame image, the black / white line phenomenon at the intersection of black and white is horizontal crosstalk.

[0067] The mechanism of lateral crosstalk is that when the voltage on the data line jumps, it will cause the pixel common voltage (Vcom) to couple, resulting in fluctuations in the pixel common voltage. For example, the absolute value of the voltage difference when the positive frame jumps from L255+ to L32+ is H1, and the absolute value of the voltage difference when the negative frame jumps from L255- to L32- is H2. When the absolute value of the jump voltage difference H1 of the positive frame is not equal to the absolute value of the jump voltage difference H2 of the negative frame, it will cause the pixel common voltage to couple, generating a coupling voltage ΔV, such as Figure 3shown.

[0068] When the coupling voltage cannot be eliminated within a frame, white or black lines will appear at the horizontal intersection of the windows. For example, when the absolute value of the jump voltage difference in the positive frame is greater than that in the negative frame, the horizontal crosstalk phenomenon appears as a black line; when the absolute value of the jump voltage difference in the positive frame is less than that in the negative frame, the horizontal crosstalk phenomenon appears as a white line.

[0069] In response to the above problems, the present application proposes a data polarity changing method. When the absolute value of the jump voltage difference of the positive frame is greater than the absolute value of the jump voltage difference of the negative frame, the number of negative polarity data lines is increased to neutralize the positive polarity coupling voltage of the pixel common voltage. When the absolute value of the jump voltage difference of the positive frame is less than the absolute value of the jump voltage difference of the negative frame, the number of positive polarity data lines is increased to neutralize the negative polarity coupling voltage of the pixel common voltage. In this way, the coupling voltage is neutralized and reduced by changing the polarity of the data line, thereby reducing lateral crosstalk and improving the picture display effect.

[0070] The following specific embodiments are used to describe the technical solution of the present application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0071] Figure 4 A flow chart of a method for changing the polarity of a data line provided in one embodiment of the present application is shown.

[0072] like Figure 4 As shown, with the electronic device as the execution subject, the method of this embodiment may include the following steps:

[0073] S101. When a preset picture exists, if the absolute value of the jump voltage difference of the positive frame is greater than the absolute value of the jump voltage difference of the negative frame, control the number of negative polarity data lines connected to the pixels of the preset picture to be greater than the number of positive polarity data lines, so as to neutralize the positive polarity coupling voltage of the pixel common voltage.

[0074] For example, the preset picture may be a picture on the screen, such as a picture smaller than the screen, or a window picture displayed on the screen and smaller than the screen.

[0075] Alternatively, another screen can be superimposed on another screen. For example, a second screen can be displayed on a first screen, smaller than the first screen, and the grayscale values ​​of the first and second screens can be different. The specific grayscale values ​​can be determined based on actual conditions. Another example is a white frame on a black background, or a menu bar can be displayed on a single screen.

[0076] The position of the preset screen is variable. If the preset screen is smaller than the screen, the preset screen can be located anywhere on the screen; if the preset screen is a second screen superimposed on the first screen, the second screen can be located anywhere on the first screen.

[0077] Each frame has multiple pixels, and each pixel has a corresponding positive polarity data line and a negative polarity data line. In a positive frame, a voltage is applied to the positive polarity data line corresponding to each pixel, and in a negative frame, a voltage is applied to the negative polarity data line corresponding to each pixel. In two adjacent positive frames, at least some of the positive polarity data lines corresponding to the pixels have a voltage change, that is, they have a corresponding jump voltage difference absolute value; in two adjacent negative frames, at least some of the negative polarity data lines corresponding to the pixels have a voltage change, that is, they have a corresponding jump voltage difference absolute value. For example, the two adjacent positive frames are the previous positive frame and the current positive frame, and the two adjacent negative frames are the previous negative frame and the current negative frame, and the order of appearance of the previous positive frame, the current positive frame, the previous negative frame, and the current negative frame is the previous positive frame, the previous negative frame, the current positive frame, and the current negative frame.

[0078] For each pixel, when the absolute value of the jump voltage difference of the positive polarity data line of the pixel is inconsistent with the absolute value of the jump voltage difference of the negative polarity data line, the pixel common voltage of the pixel will be coupled to form a coupling voltage. The coupling voltage of the pixel can be equal to the product of the coupling coefficient and the voltage difference between the positive and negative polarity data lines. The voltage difference between the positive and negative polarity data lines is equal to the difference between the absolute value of the jump voltage difference of the positive polarity data line and the absolute value of the jump voltage difference of the negative polarity data line.

[0079] For example, a pixel has a corresponding first grayscale in the current positive frame, and the first grayscale has a corresponding first voltage. In the current positive frame, the positive polarity data line of the pixel applies the first voltage corresponding to the first grayscale; the pixel has a corresponding second grayscale in the previous positive frame, and the second grayscale has a corresponding second voltage. In the previous positive frame, the positive polarity data line of the pixel applies the second voltage corresponding to the second grayscale. Therefore, the absolute value of the jump voltage difference of the positive polarity data line of the pixel can be the absolute value of the difference between the first voltage and the second voltage. It should be noted that the absolute value of the jump voltage difference of the positive polarity data line of the pixel can also be called the absolute value of the jump voltage difference of the pixel in the positive frame.

[0080] Similarly, if a pixel has a corresponding third grayscale in the current negative frame, and the third grayscale has a corresponding third voltage, then in the current negative frame, the negative polarity data line of the pixel applies the third voltage corresponding to the third grayscale; if the pixel has a corresponding fourth grayscale in the previous negative frame, and the fourth grayscale has a corresponding fourth voltage, then in the previous negative frame, the negative polarity data line of the pixel applies the fourth voltage corresponding to the fourth grayscale. Therefore, the absolute value of the jump voltage difference of the negative polarity data line of the pixel can be the absolute value of the difference between the third voltage and the fourth voltage. The absolute value of the jump voltage difference of the negative polarity data line of the pixel can also be called the absolute value of the jump voltage difference of the pixel in the negative frame.

[0081] For example, a pixel had a first grayscale of L255+ in the previous positive frame, and the corresponding voltage of L255+ was 13.91V. In the current positive frame, the pixel has a second grayscale of L32+, and the corresponding voltage of L32+ was 9.7V. Therefore, the absolute value of the transition voltage difference of the pixel in the positive frame is H1 = 13.91V - 9.7V = 4.21V. In the previous negative frame, the pixel had a third grayscale of L255-, and the corresponding voltage of L255- was 0.32V. In the current negative frame, the pixel has a fourth grayscale of L32-, and the corresponding voltage of L32- was 4.42V. Therefore, the absolute value of the transition voltage difference of the pixel in the negative frame is H2 = 4.42V - 0.32V = 4.1V. The coupling voltage of this pixel is equal to x(4.42 - 4.1V), where x is the coupling coefficient.

[0082] For ease of description, the absolute value of the transition voltage difference of the positive polarity data line of each pixel is referred to as the first absolute value of the difference, and the absolute value of the transition voltage difference of the negative polarity data line of each pixel is referred to as the second absolute value of the difference. The average of the first absolute value of the difference of each pixel is referred to as the first average value, also known as the transition voltage absolute value of the positive frame. The average of the second absolute value of the difference of each pixel is referred to as the second average value, also known as the transition voltage absolute value of the negative frame.

[0083] It can be understood that when the absolute value of the jump voltage difference of the positive frame is greater than the absolute value of the jump voltage difference of the negative frame, a positive polarity coupling voltage is formed, and the positive polarity coupling voltage is greater than 0. When the absolute value of the jump voltage difference of the positive frame is less than the absolute value of the jump voltage of the negative frame, a negative polarity coupling voltage is formed, and the negative polarity coupling voltage is less than 0.

[0084] In this step, if the absolute value of the jump voltage difference of the positive frame is greater than the absolute value of the jump voltage difference of the negative frame, the number of negative polarity data lines connected to the pixels of the preset image is controlled to be greater than the number of positive polarity data lines to neutralize the positive polarity coupling voltage of the pixel common voltage.

[0085] It can be understood that the absolute value of the transition voltage difference in the positive frame is greater than the absolute value of the transition voltage difference in the negative frame, which means that the absolute value of the transition voltage difference of the positive polarity data lines of some pixels is greater than the absolute value of the transition voltage difference of the negative polarity data lines. If the number of negative polarity data lines is increased, some pixels can be located between the negative polarity data lines. In this way, the coupling voltage of the pixel common voltage between the negative polarity data lines of these pixels is less than zero, thereby neutralizing some of the positive polarity coupling voltage, thereby reducing the total coupling voltage. The total coupling voltage can be understood as the sum of the individual coupling voltages.

[0086] In some embodiments, it is possible to detect whether a black preset image or a white preset image exists under a certain grayscale background brightness. If so, when the absolute value of the jump voltage difference of the positive frame is greater than the absolute value of the jump voltage difference of the negative frame, the number of negative polarity data lines in the data lines connected to the pixels controlling the preset image is greater than the number of positive polarity data lines.

[0087] In some embodiments, some positive polarity data lines in the data lines connected to the pixels of the preset screen can be modified to negative polarity data lines so that the number of negative polarity data lines is greater than the number of positive polarity data lines, thereby neutralizing the positive polarity coupling voltage of the pixel common voltage.

[0088] S102 : If the absolute value of the jump voltage difference of the positive frame is smaller than the absolute value of the jump voltage difference of the negative frame, control the number of positive polarity data lines connected to the pixels of the preset image to be greater than the number of negative polarity data lines to neutralize the negative polarity coupling voltage of the pixel common voltage.

[0089] It can be understood that the absolute value of the transition voltage difference in the positive frame is smaller than the absolute value of the transition voltage difference in the negative frame, which means that the absolute value of the transition voltage difference of the positive polarity data lines of some pixels is smaller than the absolute value of the transition voltage difference of the negative polarity data lines. If the number of positive polarity data lines is increased, some pixels can be located between the positive polarity data lines. In this way, the coupling voltage of the pixel common voltage between the positive polarity data lines of these pixels is greater than zero, thereby neutralizing some of the negative polarity coupling voltage, thereby reducing the total coupling voltage.

[0090] Therefore, in this step, when there is a preset picture, if the absolute value of the jump voltage difference of the positive frame is greater than the absolute value of the jump voltage difference of the negative frame, the number of negative polarity data lines in the data lines connected to the pixels of the preset picture is controlled to be greater than the number of positive polarity data lines, so as to neutralize the positive polarity coupling voltage of the pixel common voltage.

[0091] In some embodiments, among the data lines connected to pixels of a preset frame, some negative polarity data lines are modified to positive polarity data lines so that the number of positive polarity data lines is greater than the number of negative polarity data lines to neutralize the negative polarity coupling voltage of the pixel common voltage.

[0092] In this embodiment, step S101 and step S102 are not limited to the order of the actions described.

[0093] The data line polarity changing method provided in the present application increases the number of negative polarity data lines to neutralize the positive polarity coupling voltage of the pixel common voltage when the absolute value of the jump voltage difference of the positive frame is greater than the absolute value of the jump voltage difference of the negative frame; increases the number of positive polarity data lines to neutralize the negative polarity coupling voltage of the pixel common voltage when the absolute value of the jump voltage difference of the positive frame is less than the absolute value of the jump voltage difference of the negative frame, thereby neutralizing and reducing the coupling voltage by changing the polarity of the data line, reducing lateral crosstalk, and improving the picture display effect.

[0094] Figure 5 A schematic diagram of a method for changing the polarity of a data line is shown. Figure 5 As shown, modifying some positive polarity data lines to negative polarity data lines may include the following steps:

[0095] S201: Select a pixel from a first preset number of pixels.

[0096] The coupling voltages of the first preset number of pixels are within a preset range. For example, the coupling voltages of the first preset number of pixels are equal to 0 or close to 0.

[0097] As can be seen from the above description, each pixel has a corresponding positive polarity data line, a negative polarity data line, and a pixel common voltage. For each pixel, the absolute value of the transition voltage difference between the positive polarity data line and the absolute value of the transition voltage difference between the negative polarity data line will cause coupling with the pixel common voltage, generating a coupled voltage. When the absolute value of the transition voltage difference between the positive polarity data line and the negative polarity data line is greater than the absolute value of the transition voltage difference between the positive polarity data line and the negative polarity data line, the pixel's coupled voltage is greater than 0.

[0098] It should be noted that the pixel coupling voltage can be equal to the product of the coupling coefficient and the voltage difference between the positive and negative polarity data lines. The voltage difference between the positive and negative polarity data lines is equal to the difference between the absolute value of the jump voltage difference of the positive polarity data line and the absolute value of the jump voltage difference of the negative polarity data line.

[0099] When a frame includes multiple pixels, the coupling voltage of the frame is equal to the sum of the coupling voltages of each pixel. For example, a frame includes n pixels, which are recorded as the 1st pixel to the nth pixel, and each pixel corresponds to a positive polarity data line and a negative polarity data line. Figure 6As shown, the coupling voltage ΔV1 of the first pixel is equal to x*(H11-H12), where H11 is the absolute value of the transition voltage difference of the positive polarity data line of the first pixel, and H12 is the absolute value of the transition voltage difference of the negative polarity data line of the first pixel; the coupling voltage ΔV2 of the second pixel is equal to x*(H21-H22), where H21 is the absolute value of the transition voltage difference of the positive polarity data line of the second pixel, and H22 is the absolute value of the transition voltage difference of the negative polarity data line of the second pixel; and so on, the coupling voltage ΔVn of the nth pixel is equal to x*(Hn1-Hn2), where Hn1 is the absolute value of the transition voltage difference of the positive polarity data line of the nth pixel, and Hn2 is the absolute value of the transition voltage difference of the negative polarity data line of the nth pixel.

[0100] The total coupling voltage is equal to the sum of the coupling voltages of the individual pixels, so ΔV=(ΔV1+ΔV2+…+ΔVn) / n=x*[(H11+H12+…+Hn1)-(H12+H22+…+Hn2)] / n.

[0101] For example, if the absolute values ​​of the transition voltage differences of the positive polarity data lines of each pixel are the same, and the absolute values ​​of the transition voltages of the negative polarity data lines of each pixel are the same, then ΔV=ΔV1=ΔV2=…=ΔVn=x*(H1-H2).

[0102] In some embodiments, when the absolute value of the transition voltage difference of the positive frame is greater than the absolute value of the transition voltage difference of the negative frame, the positive polarity data line of one pixel in the preset image is pre-modified to negative polarity. Then, the coupling voltage of each pixel is calculated and sequentially added together to obtain a first summed voltage until the first summed voltage falls within a preset range. Subsequently, the number of pixels at which the first summed voltage falls within the preset range is obtained as the first preset number.

[0103] For example, Figure 7 As shown, Figure 7 (a) is the polarity diagram of the original data line. Figure 7 (b) shows the data line polarity after the data line polarity is modified. Changing the positive polarity data line of a pixel to a negative polarity data line results in both data lines of two pixels being negative polarity data lines. For these two pixels, the coupling voltage of each pixel can be equal to the product of a preset inverse number and a coupling coefficient. Here, the preset inverse number is the sum of the absolute values ​​of the transition voltage differences of the two negative polarity data lines.

[0104] Continue to refer Figure 7As shown, taking the case of changing the positive polarity data line of the second pixel to the negative polarity data line as an example, at this time, the coupling voltage of the first pixel ΔV1 = x*(H11-H12), H11 is the absolute value of the transition voltage difference of the positive polarity data line of the first pixel, and H12 is the absolute value of the transition voltage difference of the negative polarity data line of the first pixel; the coupling voltage of the second pixel ΔV2' = -x*(H21+H22), H21 is the absolute value of the transition voltage difference of the first negative polarity data line of the second pixel, and H22 is the absolute value of the transition voltage difference of the second negative polarity data line of the second pixel; the coupling voltage of the third pixel ΔV3' = -x*(H31+H3 2), H31 is the absolute value of the transition voltage difference of the first negative polarity data line of the third pixel, and H32 is the absolute value of the transition voltage difference of the second negative polarity data line of the third pixel; the coupling voltage ΔV4 of the fourth pixel is x*(H41-H42), H41 is the absolute value of the transition voltage difference of the positive polarity data line of the fourth pixel, and H42 is the absolute value of the transition voltage difference of the negative polarity data line of the fourth pixel; and so on, the coupling voltage ΔVn of the nth pixel is x*(Hn1-Hn2), Hn1 is the absolute value of the transition voltage difference of the positive polarity data line of the nth pixel, and Hn2 is the absolute value of the transition voltage difference of the negative polarity data line of the nth pixel.

[0105] ΔV1, ΔV2', ΔV3', ΔV4, ..., ΔVn are sequentially added until the added coupling voltage is within a preset range. For example, if ΔV1+ΔV2'+ΔV3'+ΔV4=0, the first preset number is 4. For example, if ΔV1+ΔV2+ΔV3+ΔV4+ ... ΔV10=0, the first preset number is 10.

[0106] S202: Change the positive polarity data line of a selected pixel to a negative polarity data line.

[0107] According to step S201 , within the first preset number of pixels, changing the positive polarity data line of one pixel to a negative polarity data line can make the first preset number of coupling voltages within a preset range, thereby reducing the impact of lateral crosstalk.

[0108] Therefore, in this step, the positive polarity data line of a pixel selected from the first preset number of pixels is modified to a negative polarity data line to neutralize the positive polarity coupling voltage, so that the sum of the coupling voltages of the first preset number of pixels is within a preset range, reducing the impact of lateral crosstalk.

[0109] It can be understood that in the data line polarity changing method provided in this embodiment, when a frame includes n pixels, the positive polarity data line of one pixel in every first preset number of pixels is changed.

[0110] The data line polarity changing method provided in this embodiment modifies the positive polarity data line of one pixel within a first preset number of pixels into a negative polarity data line, so that the coupling voltage of the first preset number of pixels is within a preset range, reducing the impact of lateral crosstalk and improving the picture display effect.

[0111] Figure 8 A schematic diagram of a method for changing the polarity of a data line is shown. Figure 8 As shown, modifying some positive polarity data lines to negative polarity data lines may include the following steps:

[0112] S301 , selecting a pixel from a second preset number of pixels, and using a positive polarity data line of the selected pixel as a first target data line.

[0113] The coupling voltages of the second preset number of pixels are within a preset range. For example, the coupling voltages of the second preset number of pixels are equal to 0 or close to 0.

[0114] In some embodiments, when the absolute value of the transition voltage difference in a positive frame is greater than the absolute value of the transition voltage difference in a negative frame, the positive polarity data line of one pixel in a preset image is pre-determined as the third target data line, and the third target data line is modified to a negative polarity data line. Furthermore, to simplify the calculation process, the positive polarity data lines of other pixels following this pixel can be modified to negative polarity data lines, and vice versa. Specifically, the positive polarity data line following the third target data line is modified to a negative polarity data line, and the negative polarity data line following the third target data line is modified to a positive polarity data line. This leaves the coupling voltages of other pixels following this pixel unchanged. The coupling voltages of other pixels following this pixel can then be directly obtained or recalculated. In this case, the coupling voltage of a pixel whose data line polarity has changed is equal to the product of a preset inverse number and a coupling coefficient. Here, the preset inverse number is the inverse of the sum of the absolute values ​​of the transition voltage differences of the two negative polarity data lines. The coupling voltages of pixels whose data lines both change polarity remain unchanged.

[0115] Then, the coupling voltages of the pixels can be sequentially added to obtain a second summed voltage until the second summed voltage is within a preset range. Subsequently, the number of pixels when the second summed voltage is within the preset range is obtained as the second preset number.

[0116] For example, Figure 9 As shown, Figure 9 (a) is the polarity diagram of the original data line. Figure 5(b) shows the data line polarity after the data line polarity is modified. Changing the positive polarity data line of a pixel to a negative polarity data line, and then changing the positive polarity data lines of other pixels after that pixel to negative polarity data lines, and then changing the negative polarity data lines of other pixels after that pixel to positive polarity data lines, results in both data lines of a pixel being negative polarity data lines.

[0117] Continue to refer Figure 9 As shown, taking the case of changing the positive polarity data line of the second pixel to the negative polarity data line as an example, at this time, the coupling voltage of the first pixel ΔV1 = x*(H11-H12), H11 is the absolute value of the transition voltage difference of the positive polarity data line of the first pixel, and H12 is the absolute value of the transition voltage difference of the negative polarity data line of the first pixel; the coupling voltage of the second pixel ΔV2' = -x*(H21+H22), H21 is the absolute value of the transition voltage difference of the first negative polarity data line of the second pixel, and H22 is the absolute value of the transition voltage difference of the first negative polarity data line of the second pixel. The absolute value of the transition voltage difference between the two negative polarity data lines; the coupling voltage of the third pixel ΔV3 = x*(H31-H32), H31 is the absolute value of the transition voltage difference of the positive polarity data line of the third pixel, and H32 is the absolute value of the transition voltage difference of the negative polarity data line of the third pixel; and so on, the coupling voltage of the nth pixel ΔVn = x*(Hn1-Hn2), Hn1 is the absolute value of the transition voltage difference of the positive polarity data line of the nth pixel, and Hn2 is the absolute value of the transition voltage difference of the negative polarity data line of the nth pixel.

[0118] ΔV1, ΔV2', ΔV3, ΔV4, ..., ΔVn are sequentially added until the added coupling voltage is within the preset range. For example, if ΔV1+ΔV2'+ΔV3+ΔV4=0, the second preset number is 4. For example, if ΔV1+ΔV2'+ΔV3+ΔV4+ ... ΔV10=0, the second preset number is 10.

[0119] S302, modify the first target data line to a negative polarity data line, and modify the negative polarity data lines after the first target data line to positive polarity data lines and the positive polarity data lines after the first target data line to negative polarity data lines among the data lines corresponding to the second preset number of pixels.

[0120] According to step S301, within the second preset number of pixels, the positive polarity data line of one pixel is modified to a negative polarity data line, and the positive polarity data lines and negative polarity data lines of other pixels after the pixel are interchanged, so that only the coupling voltage of one pixel is changed, the calculation process is simplified, and the coupling voltage of the second preset number can be within a preset range, thereby reducing the impact of lateral crosstalk.

[0121] Therefore, in this step, the first target data line is modified to a negative polarity data line, and among the data lines corresponding to the second preset number of pixels, the negative polarity data line after the first target data line is modified to a positive polarity data line, and the positive polarity data line after the first target data line is modified to a negative polarity data line, so as to neutralize the positive polarity coupling voltage, so that the sum of the coupling voltages of the second preset number of pixels is within the preset range, thereby reducing the impact of lateral crosstalk.

[0122] The data line polarity changing method provided in this embodiment modifies the positive polarity data line of one pixel within a second preset number of pixels into a negative polarity data line, and interchanges the positive polarity data lines and negative polarity data lines of other pixels after the pixel, thereby changing only the coupling voltage of one pixel, simplifying the calculation process, and enabling the coupling voltage of the second preset number to be within a preset range, thereby reducing the impact of lateral crosstalk.

[0123] Figure 10 A schematic diagram of a method for changing the polarity of a data line is shown. Figure 6 As shown, modifying some negative polarity data lines to positive polarity data lines may include the following steps:

[0124] S401: Select a pixel from a third preset number of pixels.

[0125] The coupling voltages of the third preset number of pixels are within a preset range. For example, the coupling voltages of the third preset number of pixels are equal to 0 or close to 0.

[0126] In some embodiments, when the absolute value of the transition voltage difference in a positive frame is smaller than the absolute value of the transition voltage difference in a negative frame, the negative polarity data line of one pixel in a preset image is pre-set as the fourth target data line, and the fourth target data line is modified to a positive polarity data line. Then, the coupling voltage of each pixel is calculated, and the coupling voltages of each pixel are sequentially added together to obtain a third summed voltage until the third summed voltage falls within a preset range. Subsequently, the number of pixels at which the added coupling voltage falls within the preset range is obtained as the third preset number.

[0127] For example, Figure 11 As shown, Figure 11 (a) is the polarity diagram of the original data line. Figure 11 (b) shows the data line polarity after the data line polarity is modified. Changing a pixel's negative data line to a positive data line results in both data lines being positive for both pixels. For these two pixels, the coupling voltage for each pixel can be equal to the product of the sum of the absolute values ​​of the transition voltage differences of the two positive data lines and the coupling coefficient.

[0128] Continue to refer Figure 11As shown, taking the modification of the negative polarity data line of the first pixel to the positive polarity data line as an example, at this time, the coupling voltage of the first pixel ΔV1'=x*(H11+H12), H11 is the absolute value of the transition voltage difference of the first positive polarity data line of the first pixel, and H12 is the absolute value of the transition voltage difference of the second data line of the first pixel; the coupling voltage of the second pixel ΔV2'=x*(H21+H22), H21 is the absolute value of the transition voltage difference of the first positive polarity data line of the second pixel, and H22 is the absolute value of the transition voltage difference of the second positive polarity data line of the second pixel; the coupling voltage of the third pixel ΔV3=x*(H31 -H32), H31 is the absolute value of the transition voltage difference of the positive polarity data line of the 3rd pixel, and H32 is the absolute value of the transition voltage difference of the negative polarity data line of the 3rd pixel; the coupling voltage ΔV4 of the 4th pixel is x*(H41-H42), H41 is the absolute value of the transition voltage difference of the positive polarity data line of the 4th pixel, and H42 is the absolute value of the transition voltage difference of the negative polarity data line of the 4th pixel; and so on, the coupling voltage ΔVn of the nth pixel is x*(Hn1-Hn2), Hn1 is the absolute value of the transition voltage difference of the positive polarity data line of the nth pixel, and Hn2 is the absolute value of the transition voltage difference of the negative polarity data line of the nth pixel.

[0129] ΔV1′, ΔV2′, ΔV3, ΔV4, …, ΔVn are sequentially added until the added coupling voltage is within a preset range. For example, if ΔV1′+ΔV2′+ΔV3+ΔV4=0, the first preset number is 4. For example, if ΔV1′+ΔV2′+ΔV3+ΔV4+ …ΔV10=0, the first preset number is 10.

[0130] S402: Change the negative polarity data line of a selected pixel to a positive polarity data line.

[0131] According to step S401 , among the third preset number of pixels, changing the negative polarity data line of one pixel to a positive polarity data line can make the third preset number of coupling voltages within a preset range, thereby reducing the impact of lateral crosstalk.

[0132] Therefore, in this step, the negative polarity data line of a pixel selected from the third preset number of pixels is modified to a positive polarity data line to neutralize the negative polarity coupling voltage, so that the sum of the coupling voltages of the third preset number of pixels is within the preset range, reducing the impact of lateral crosstalk.

[0133] The data line polarity changing method provided in this embodiment modifies the negative polarity data line of one pixel within a third preset number of pixels into a positive polarity data line, so that the coupling voltage of the third preset number of pixels is within a preset range, reducing the impact of lateral crosstalk and improving the picture display effect.

[0134] Figure 12 A schematic diagram of a method for changing the polarity of a data line is shown. Figure 12 As shown, modifying some negative polarity data lines to positive polarity data lines may include the following steps:

[0135] S501 , selecting a pixel from a fourth preset number of pixels, and using the negative polarity data line of the selected pixel as a second target data line.

[0136] The coupling voltages of the fourth preset number of pixels are within a preset range. For example, the coupling voltages of the fourth preset number of pixels are equal to 0 or close to 0.

[0137] In some embodiments, when the absolute value of the transition voltage difference in a positive frame is less than the absolute value of the transition voltage difference in a negative frame, the negative polarity data line of one pixel in a preset image is pre-modified to positive polarity. To simplify the calculation process, the positive polarity data lines of the pixels following this pixel can be modified to negative polarity data lines. Modifying the negative polarity data lines to positive polarity data lines leaves the coupling voltages of the pixels following this pixel unchanged. The coupling voltages of the pixels following this pixel can then be directly obtained or recalculated. In this case, the coupling voltage of the pixel whose data line polarity has changed is equal to the product of the sum of the absolute values ​​of the transition voltage differences of the two positive polarity data lines and the coupling coefficient. The coupling voltages of the pixel whose data lines both have changed polarity remain unchanged.

[0138] Then, the coupling voltages of the pixels can be sequentially added to obtain a fourth summed voltage until the fourth summed voltage is within a preset range. Subsequently, the number of pixels when the added coupling voltages are within the preset range is obtained as the fourth preset number.

[0139] For example, Figure 13 As shown, Figure 13 (a) is the polarity diagram of the original data line. Figure 13 (b) shows the data line polarity after the data line polarity is modified. Changing the negative data line of a pixel to a positive data line, and then changing the positive data lines of the pixels following it to negative data lines, and then changing the negative data lines of the pixels following it to positive data lines, results in both data lines of a pixel being negative.

[0140] Continue to refer Figure 13As shown, taking the modification of the negative polarity data line of the first pixel to the positive polarity data line as an example, at this time, the coupling voltage of the first pixel ΔV1'=x*(H11+H12), H11 is the absolute value of the transition voltage difference of the first positive polarity data line of the first pixel, and H12 is the absolute value of the transition voltage difference of the second positive polarity data line of the first pixel; the coupling voltage of the second pixel ΔV2=x*(H21-H22), H21 is the absolute value of the transition voltage difference of the positive polarity data line of the second pixel, and H22 is the absolute value of the transition voltage difference of the second pixel. The coupling voltage of the third pixel ΔV3 = x*(H31-H32), where H31 is the absolute value of the transition voltage difference of the positive polarity data line of the third pixel, and H32 is the absolute value of the transition voltage difference of the negative polarity data line of the third pixel; and so on, the coupling voltage of the nth pixel ΔVn = x*(Hn1-Hn2), where Hn1 is the absolute value of the transition voltage difference of the positive polarity data line of the nth pixel, and Hn2 is the absolute value of the transition voltage difference of the negative polarity data line of the nth pixel.

[0141] ΔV1′, ΔV2, ΔV3, ΔV4, …, ΔVn are sequentially added until the added coupling voltage is within a preset range. For example, if ΔV1′+ΔV2+ΔV3+ΔV4=0, the second preset number is 4. For example, if ΔV1′+ΔV2+ΔV3+ΔV4+ …ΔV10=0, the second preset number is 10.

[0142] S502: Modify the second target data line to a positive polarity data line, and among the data lines corresponding to the fourth preset number of pixels, modify the negative polarity data lines after the second target data line to positive polarity data lines, and modify the positive polarity data lines after the first target data line to negative polarity data lines.

[0143] According to step S501, within the fourth preset number of pixels, the negative polarity data line of one pixel is modified to a positive polarity data line, and the positive polarity data lines and negative polarity data lines of other pixels after the pixel are interchanged, so that only the coupling voltage of one pixel is changed, the calculation process is simplified, and the coupling voltage of the fourth preset number can be within the preset range, thereby reducing the impact of lateral crosstalk.

[0144] Therefore, in this step, the second target data line is modified to a positive polarity data line, and among the data lines corresponding to the fourth preset number of pixels, the positive polarity data line after the second target data line is modified to a negative polarity data line, and the negative polarity data line after the second target data line is modified to a positive polarity data line, so as to neutralize the negative polarity coupling voltage, so that the sum of the coupling voltages of the fourth preset number of pixels is within the preset range, thereby reducing the impact of lateral crosstalk.

[0145] The data line polarity changing method provided in this embodiment modifies the negative polarity data line of one pixel within a fourth preset number of pixels into a negative polarity data line, and interchanges the positive polarity data lines and negative polarity data lines of other pixels after the pixel, thereby only changing the coupling voltage of one pixel, simplifying the calculation process, and enabling the coupling voltage of the fourth preset number to be within a preset range, thereby reducing the impact of lateral crosstalk.
