[0069] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. And in the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0070] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0071] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual scale and are only for the purpose of illustrating the present disclosure. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0072] See also Figure 1 and Figure 2The display device may include a display panel 100 and a timing controller 200. The display panel 100 may include a plurality of pixel units arranged in an array, a plurality of gate lines GA (e.g., GA1, GA2, GA3, GA4), a plurality of data lines DA (e.g., DA1, DA2, DA3), a gate driver circuit 110, and a source driver circuit 120. The gate driver circuit 110 is coupled to the gate lines GA1, GA2, GA3, GA4, respectively, and the source driver circuit 120 is coupled to the data lines DA1, DA2, DA3, respectively. The timing controller 200 may input a control signal to the gate driver circuit 110 through a level shift circuit, thereby driving the gate lines GA1, GA2, GA3, GA4. The timing controller 200 inputs a signal to the source driver circuit 120, so that the source driver circuit 120 inputs a data voltage to the data line, thereby charging the sub-pixel SPX, so that the sub-pixel SPX inputs the corresponding data voltage, and realizes the screen display function. For example, two source driver circuits 120 may be provided, wherein one source driver circuit 120 is connected to half the number of data lines, and the other source driver circuit 120 is connected to the other half of the number of data lines. Of course, three, four, or more source driver circuits 120 may also be provided, which may be designed and determined according to the needs of actual application and is not limited here.

[0073] Exemplarily, each pixel unit includes a plurality of sub-pixels SPX. For example, a pixel unit may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel, thereby enabling color display by mixing red, green, and blue. Alternatively, a pixel unit may include a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel, thereby enabling color display by mixing red, green, blue, and white. Of course, in actual applications, the luminous colors of the sub-pixels in a pixel unit can be designed and determined based on the actual application environment, and are not limited here.

[0074] See also Figure 2 As shown, each sub-pixel SPX includes a transistor 01 and a pixel electrode 02. Among them, a row of sub-pixels SPX corresponds to a gate line, and a column of sub-pixels SPX corresponds to a data line. The gate of transistor 01 is electrically connected to the corresponding gate line, the source of transistor 01 is electrically connected to the corresponding data line, and the drain of transistor 01 is electrically connected to the pixel electrode 02. It should be noted that the pixel array structure disclosed in the present invention can also be a dual-gate structure, that is, two gate lines are set between two adjacent rows of pixels. This arrangement can reduce half of the data lines, that is, some data lines are included between two adjacent columns of pixels, and some data lines are not included between two adjacent columns of pixels. The specific pixel arrangement structure and data lines, and the arrangement of the scan lines are not limited.

[0075] It should be noted that the display panel in the embodiment of the present disclosure may be a liquid crystal display panel. For example, a liquid crystal display panel generally includes an upper substrate and a lower substrate of a pair of cells, and liquid crystal molecules encapsulated between the upper substrate and the lower substrate. When displaying an image, due to the voltage difference between the data voltage applied to the pixel electrode of each sub-pixel SPX and the common electrode voltage on the common electrode, this voltage difference can form an electric field, thereby causing the liquid crystal molecules to deflect under the action of the electric field. Due to the different intensities of the electric field, the degree of deflection of the liquid crystal molecules is different, resulting in different transmittances of the sub-pixels SPX, so that the sub-pixels SPX can achieve different grayscale brightness, thereby realizing image display.

[0076] In the embodiment of the present disclosure, a display panel including red sub-pixels R11 to R21, green sub-pixels G11 to G21, blue sub-pixels B11 to B21, red sub-pixels R12 to R22, green sub-pixels G12 to G22, and blue sub-pixels B12 to B82 is taken as an example. Figures 3 to 5 As shown, the pixel electrode 02 may include a first edge conductive portion 101 and a second edge conductive portion 102 arranged alternately in the first direction Y, and a main conductive portion at least partially located between the first edge conductive portion 101 and the second edge conductive portion 102. The main conductive portion is connected to the first edge conductive portion 101 and the second edge conductive portion 102, respectively, and may include at least one first group of sub-conductive portions and at least one second group of sub-conductive portions. The first group of sub-conductive portions and the second group of sub-conductive portions are alternately arranged in the first direction Y.

[0077] Furthermore, the first group of sub-conductive portions may include a first connecting bar 103 and a plurality of first electrode bars 104 spaced apart in a first direction Y. The first connecting bar 103 extends in the first direction Y (i.e., the length direction of the first connecting bar 103 is the first direction Y). The first connecting bar 103 may have a first surface 103a and a second surface 103b that are opposite to each other in a second direction X. It should be noted that the first direction Y may intersect with the second direction X. Preferably, the first direction Y may be perpendicular to the second direction X (for example, the first direction Y may be the column direction F of the sub-pixels, and the second direction X may be the row direction X of the sub-pixels). The plurality of first electrode bars 104 may be located on the first surface 103a away from the second surface 103b and connected to the first surface 103a. Among them, a gap is formed between two adjacent first electrode strips 104, which can be defined as a first gap S1. The ends of the two adjacent first electrode strips 104 away from the first connecting strip 103 are disconnected from each other, that is, the end of the first gap S1 away from the first connecting strip 103 is open. For the convenience of description, the end of the first gap S1 away from the first connecting strip 103 can be defined as an open end.

[0078] Furthermore, the second group of sub-conductive portions includes a second connecting strip 105 and a plurality of second electrode strips 106 spaced apart in a first direction Y. The second connecting strip 105 extends in the first direction Y (i.e., the length of the second connecting strip 105 is the first direction Y). The second connecting strip 105 may have a third surface 105a and a fourth surface 105b that are opposed to each other in the second direction X. In the second direction X, the third surface 105a of the second connecting strip 105 may be located on a side of the fourth surface 105b of the second connecting strip 105 that is closer to the first surface 103a of the first connecting strip 103. The third surface 105a of the second connecting strip 105 may be connected to the first electrode strip 104 near the second group of sub-conductive portions, specifically to the end of the first electrode strip 104 that is away from the first connecting strip 103. It should be understood that the first electrode strip 104 near the second group of sub-conductive portions mentioned here refers to the first electrode strip 104 in the first group of sub-conductive portions that is closest to the second group of sub-conductive portions. The plurality of second electrode strips 106 are located on the third surface 105a of the second connecting strip 105, away from the fourth surface 105b, and are connected to the third surface 105a of the second connecting strip 105. A gap, which can be defined as a second gap S2, is formed between two adjacent second electrode strips 106. The ends of the two adjacent second electrode strips 106 away from the second connecting strip 105 are disconnected from each other, i.e., the end of the second gap S2 away from the second connecting strip 105 is open. For ease of description, the end of the second gap S2 away from the second connecting strip 105 can be defined as the open end.

[0079] Furthermore, the sum of the lengths of the first connecting bars 103 of each first group of sub-conductive parts in the pixel electrode 02 can be designed to be smaller than the sum of the lengths of the second connecting bars 105 of each second group of sub-conductive parts; it should be noted that the length mentioned here refers to the length in its extension direction.

[0080] Furthermore, the pixel electrode 02 can connect to the transistor 01 (eg, Figure 2 and Figure 5 Specifically, the end of the first edge conductive portion 101 or the second edge conductive portion 102 away from the second connecting bar 105 can be configured to be connected to the transistor 01.

[0081] In the embodiment of the present disclosure, Figures 3 to 5 As shown, in two adjacent sub-pixels (e.g., R11 and G11) along the row direction X or the column direction F, the first edge conductive portion 101 in the first sub-pixel (e.g., R11) is disposed close to the transistor 01, and the second edge conductive portion 102 is disposed away from the transistor 01, and the second connecting bar 105 is disposed close to the second sub-pixel (e.g., G11) of the two adjacent sub-pixels, and the first connecting bar 103 is away from the second sub-pixel (e.g., G11).

[0082] In the embodiment of the present disclosure, Figures 3 to 5 As shown, the first edge conductive portion 101 in the second sub-pixel (e.g., G11) is arranged away from the transistor 01, and the second edge conductive portion 102 is arranged close to the transistor 01, and the second connecting bar 105 is away from the first sub-pixel (e.g., R11) of the two adjacent sub-pixels, and the first connecting bar 103 is close to the first sub-pixel (e.g., R11).

[0083] In the embodiment of the present disclosure, Figures 3 to 5 As shown, in the first sub-pixel (eg, R11) and the second sub-pixel (eg, C11), the number of second electrode strips 106 connected to the second connecting strip 105 is different.

[0084] In the embodiment of the present disclosure, Figures 3 to 5 As shown, in the first sub-pixel (eg, R11) and the second sub-pixel (eg, G11), the number of first electrode strips 104 connected to the first connecting strip 103 is different.

[0085] In the embodiment of the present disclosure, Figures 3 to 5 As shown, multiple common electrodes are also provided between the pixel electrode 02 and the base substrate. A common electrode is provided for each row of sub-pixels; the display panel further includes multiple jumpers KB; and two adjacent common electrodes are electrically connected via at least one jumper KB. Furthermore, within the same sub-pixel, the first connecting bar 103 and the second connecting bar 105 are connected via a transition portion ZB; the transition portion ZB has a hollow region LB. This can improve the electrical connection performance between the first connecting bar 103 and the second connecting bar 105. Furthermore, for liquid crystal displays, the location of the hollow region LB can form an electric field that drives the liquid crystal to rotate. Furthermore, the present invention includes the possibility that the transition portions of two adjacent pixel electrodes are not on the same horizontal line. For example, the transition portion corresponding to the G11 pixel is further away from the position of the transistor to which it is connected than the transition portion corresponding to the R11 pixel.

[0086] It should be noted that the common electrode may be strip-shaped, or the common electrode may have multiple common sub-electrodes like the pixel electrode, and adjacent common sub-electrodes are connected through horizontal and vertical jumper portions to achieve common voltage transmission.

[0087] In summary, in the embodiment of the present disclosure, the first slit S1 and the second slit S2 of the pixel electrode 02 are not completely closed around, that is, the end of the first slit S1 close to the second connecting bar 105 is an open end, and the end of the second slit S2 close to the first connecting bar 103 is an open end. It should be understood that when the pixel electrode 02 of the embodiment of the present disclosure is applied to a display product, the open end of the first slit S1 and the open end of the second slit S2 can be respectively connected to the data lines DA on both sides of the pixel electrode 02 (such as Figure 2 and Figure 5When used in liquid crystal display products, it can effectively reduce the range of the dark field area of ​​the liquid crystal display products, thereby improving the transmittance of the liquid crystal display products and improving color deviation.

[0088] In the embodiment of the present disclosure, Figure 4 and Figure 5 As shown, the first electrode strips 104 and the second electrode strips 106 can extend in the same direction, that is, the first electrode strips 104 and the second electrode strips 106 can extend in the same direction. In other words, the pixel electrode 02 of the present disclosure can have a single-domain structure, which can reduce design difficulty. It should be noted that in this embodiment, the gap between adjacent first electrode strips 104 and second electrode strips 106 can be the second gap S2 mentioned above.

[0089] In the embodiment of the present disclosure, Figure 4 and Figure 5 As shown, the first electrode strips 104 and the first slits S1 extend in the same direction to ensure display uniformity at the first group of sub-conductive portions of the pixel electrode 02; and the extension directions of the first electrode strips 104 and the first slits S1 intersect with the first direction Y and the second direction X mentioned above to reduce color shift. Similarly, the second electrode strips 106 and the second slits S2 extend in the same direction to ensure display uniformity at the second group of sub-conductive portions of the pixel electrode 02; and the extension directions of the second electrode strips 106 and the second slits S2 intersect with the first direction Y and the second direction X mentioned above to reduce color shift. Figure 5 In two adjacent pixel units, such as R11 and G11, the second electrode bar 106 of R11 is connected to the second connecting bar 105 and extends toward the left, the first electrode bar 104 of G11 is connected to the first connecting bar 103 and extends toward the right, the first electrode bar 104 of R11 is connected to the first connecting bar 103 and extends toward the right, and the second electrode bar 106 of G11 is connected to the second connecting bar 105 and extends toward the left. Such a pixel design improves the problem of display color deviation.

[0090] It should be noted that, in the embodiments of the present disclosure, only the pixel electrode adopts the above structure for illustration. In practical applications, the common electrode can also be configured in the above structure of the pixel electrode, which is not limited here.

[0091] The following description takes the display panel in the embodiments of the present disclosure as a liquid crystal display panel, and the pixel unit includes red sub-pixels, green sub-pixels, and blue sub-pixels as an example, but readers should know that the colors of the sub-pixels included in the liquid crystal display panel are not limited to this.

[0092] Grayscale generally divides the brightness change between the darkest and brightest into several parts to facilitate screen brightness control. For example, the image displayed is composed of three colors: red, green, and blue. Each color can show a different brightness level, and the combination of red, green, and blue with different brightness levels can form different colors. For example, the grayscale bit number of the LCD panel is 6 bits, and the three colors of red, green, and blue have 64 (i.e. 2 6 ) grayscale, these 64 grayscale values ​​are 0 to 63. The grayscale number of the LCD panel is 8 bits, so the three colors of red, green and blue have 256 (i.e. 2 8 ) grayscale, these 256 grayscale values ​​are 0 to 255. The grayscale bit number of the LCD panel is 10 bits, so the three colors of red, green and blue have 1024 (i.e. 2 10 ) grayscale, these 1024 grayscale values ​​are 0 to 1023. The grayscale number of the LCD panel is 12 bits, so the three colors of red, green and blue have 4096 (i.e. 2 12 ) grayscales, and these 4096 grayscale values ​​are 0 to 4093.

[0093] For example, taking a subpixel SPX as an example, when the data voltage Vda1 input to the pixel electrode of the subpixel SPX is greater than the common electrode voltage Vcom, the liquid crystal molecules in the subpixel SPX can be made positive polarity, and the polarity corresponding to the data voltage Vda1 in the subpixel SPX is positive polarity. When the data voltage Vda2 input to the pixel electrode of the subpixel SPX is less than the common electrode voltage Vcom, the liquid crystal molecules in the subpixel SPX can be made negative polarity, and the polarity corresponding to the data voltage Vda2 in the subpixel SPX is negative polarity. For example, the common electrode voltage can be 8.3V. If a data voltage of 8.8V to 16V is input to the pixel electrode of the subpixel SPX, the liquid crystal molecules in the subpixel SPX can be made positive polarity, and the data voltage of 8.8V to 16V is the data voltage corresponding to the positive polarity. If a data voltage of 0.6V to 7.8V is input to the pixel electrode of subpixel SPX, the liquid crystal molecules in subpixel SPX can be made negatively polarized. The data voltage of 0.6V to 7.8V corresponds to the negative polarity data voltage. For example, taking an 8-bit grayscale of 0 to 255 as an example, if a data voltage of 16V is input to the pixel electrode of subpixel SPX, subpixel SPX can achieve the brightness of the maximum grayscale value (i.e., grayscale value 255) using a positive polarity data voltage. If a data voltage of 0.6V is input to the pixel electrode of subpixel SPX, subpixel SPX can achieve the brightness of the maximum grayscale value (i.e., grayscale value 255) using a negative polarity data voltage. It should be noted that there may be a voltage difference between the data voltage for grayscale value 0 and the common electrode voltage. For example, if the common electrode voltage is 8.3V, the positive polarity data voltage corresponding to grayscale value 0 may be 8.8V, and the negative polarity data voltage corresponding to grayscale value 0 may be 7.8V. Of course, the data voltage of the grayscale value 0 may be the same as the common electrode voltage. In practical applications, this can be determined according to the needs of the practical application and is not limited here.

[0094] In order to further improve color shift, a driving method is proposed. The driving method may include: generating a first display grayscale value and a second display grayscale value according to the original grayscale value of each sub-pixel of the image to be displayed, and in each display frame, using the first display grayscale value and the second display grayscale value to control one of the adjacent sub-pixels on the display panel to display a higher brightness using the first display grayscale value and the other sub-pixel to display a lower brightness using the second display grayscale value, wherein the first display grayscale value is greater than the second display grayscale value, so that the data voltages applied to the two adjacent sub-pixels are different. For example, combined with Figure 3As shown, in the nth display frame F_n, the red sub-pixel R11, the green sub-pixel G21, the blue sub-pixel B11, the red sub-pixel R22, the green sub-pixel G12, and the blue sub-pixel B22 use the first display grayscale value to display a higher brightness, and the red sub-pixel R21, the green sub-pixel G11, the blue sub-pixel B21, the red sub-pixel R12, the green sub-pixel G22, and the blue sub-pixel B12 use the second display grayscale value to display a lower brightness. In the n+1th display frame F_n+1, the red sub-pixel R11, the green sub-pixel G21, the blue sub-pixel B11, the red sub-pixel R22, the green sub-pixel G12, and the blue sub-pixel B22 also use the first display grayscale value to display a higher brightness, and the red sub-pixel R21, the green sub-pixel G11, the blue sub-pixel B21, the red sub-pixel R12, the green sub-pixel G22, and the blue sub-pixel B12 also use the second display grayscale value to display a lower brightness. In the (n+2)th display frame F_n+2, the red sub-pixel R11, green sub-pixel G21, blue sub-pixel B11, red sub-pixel R22, green sub-pixel G12, and blue sub-pixel B22 also use the first display grayscale value to display a higher brightness, while the red sub-pixel R21, green sub-pixel G11, blue sub-pixel B21, red sub-pixel R12, green sub-pixel G22, and blue sub-pixel B12 also use the second display grayscale value to display a lower brightness. This causes sub-pixels with the same domain orientation to consistently display higher or lower brightness. As a result, when the liquid crystal molecules correspond to the short axis, the image will appear bluish, and when they correspond to the long axis, the image will appear yellowish. Consequently, there is a color shift problem between left and right viewing angles.

[0095] Embodiments of the present disclosure provide a method for driving a display panel. The display panel operates over multiple consecutive display frames. During these multiple consecutive display frames, if subpixels in the same region have the same current raw grayscale value, the raw grayscale value can be converted into two grayscale values: a first target grayscale value and a second target grayscale value. If the first target grayscale value is greater than the current raw grayscale value, the luminance corresponding to the first target grayscale value displayed by the subpixel can be greater than the luminance corresponding to the current raw grayscale value displayed. Furthermore, if the second target grayscale value is less than the current raw grayscale value, the luminance corresponding to the second target grayscale value displayed by the subpixel can be less than the luminance corresponding to the current raw grayscale value displayed. Thus, the luminance corresponding to the first target grayscale value and the luminance corresponding to the second target grayscale value are mixed to achieve the luminance corresponding to the current raw grayscale value. Furthermore, in the current display frame, a data voltage corresponding to the first target grayscale value is input to a first subpixel unit SPX-1 in the control region, and a data voltage corresponding to the second target grayscale value is input to a second subpixel unit SPX-2 in the control region. In the next display frame, the first sub-pixel unit SPX-1 in the control area is input with a data voltage corresponding to the second target grayscale value, and the second sub-pixel unit SPX-2 in the control area is input with a data voltage corresponding to the first target grayscale value. This allows sub-pixels with brighter brightness in the current display frame to display darker brightness in the next display frame. Sub-pixels with darker brightness in the current display frame to display brighter brightness in the next display frame. This improves color shift by combining temporal and spatial color mixing.

[0096] like Figure 6 As shown, the embodiment of the present disclosure provides a method for driving a display panel, which may include the following steps:

[0097] S100 : In a plurality of consecutive display frames, when sub-pixels in a same area have the same current original grayscale values, convert the current original grayscale values ​​into a first target grayscale value and a second target grayscale value.

[0098] Exemplarily, step S100 may include receiving raw display data for each subpixel in a plurality of consecutive display frames. The raw display data includes a digital voltage format corresponding to a data voltage carrying a corresponding grayscale value for each subpixel, and the grayscale value corresponding to the data voltage is the raw grayscale value. In this manner, the current raw grayscale value of each subpixel in the plurality of consecutive display frames can be determined based on the raw display data for each subpixel in the plurality of consecutive display frames.

[0099] In the embodiment of the present disclosure, based on the current original grayscale values ​​of each sub-pixel in these multiple consecutive display frames, it can be determined whether there are sub-pixels in the same area with the same original grayscale values. If so, it means that the area displays a picture of the same grayscale, which is prone to color cast. For example, the original grayscale values ​​corresponding to the sub-pixels in the area are all 127 grayscale values, so the picture displayed in the area may be a grayscale picture. For example, the original grayscale values ​​corresponding to the sub-pixels in the area are all 255 grayscale values, so the picture displayed in the area may be a white picture (for example, the area is displayed as white clouds). Therefore, in order to improve color cast, the current original grayscale value can be converted into a first target grayscale value and a second target grayscale value. Moreover, the first target grayscale value is greater than the current original grayscale value, and the second target grayscale value is less than the current original grayscale value. For example, taking the grayscale range of 0 to 255 as an example, if the current original grayscale value is 127 grayscale value, the first target grayscale value can be set to 170 grayscale value and the second target grayscale value can be set to 40 grayscale value.

[0100] It should be noted that the area may be the entire area of ​​the picture displayed by the display panel, or may be one or more areas in a partial area of ​​the picture displayed by the display panel, which is not limited here.

[0101] S200. In a current display frame of a plurality of consecutive display frames, the first sub-pixel unit SPX-1 in the control area inputs a data voltage corresponding to a first target grayscale value, and the second sub-pixel unit SPX-2 in the control area inputs a data voltage corresponding to a second target grayscale value.

[0102] In the disclosed embodiment, the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 each include at least one sub-pixel. For example, the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 may include the same number of sub-pixels. Alternatively, the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 may include different numbers of sub-pixels. In practical applications, this number can be determined based on actual application requirements and is not limited herein.

[0103] In the embodiment of the present disclosure, at least one first sub-pixel unit SPX-1 and at least one second sub-pixel unit SPX-2 may be adjacent to each other. For example, the sub-pixels may be arranged in the order of the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 in the row direction X and the column direction F, respectively. For example, the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 each include one sub-pixel. Figure 7As shown, taking the red sub-pixels R11 to R81, the green sub-pixels G11 to G81, the blue sub-pixels B11 to B81, the red sub-pixels R12 to R82, the green sub-pixels G12 to G82, the blue sub-pixels B12 to B82, the red sub-pixels R13 to R83, the green sub-pixels G13 to G83 and the blue sub-pixels B13 to B83 as an example, in the first row of sub-pixels, the red sub-pixel R11 is used as a first sub-pixel unit SPX-1, and the green sub-pixel G11 is used as a second sub-pixel unit SPX-2. The pixel unit SPX-2, the blue sub-pixel B11 serves as a first sub-pixel unit SPX-1, the red sub-pixel R11 serves as a second sub-pixel unit SPX-2, the green sub-pixel G12 serves as a first sub-pixel unit SPX-1, the blue sub-pixel B12 serves as a second sub-pixel unit SPX-2, the red sub-pixel R13 serves as a first sub-pixel unit SPX-1, the green sub-pixel G13 serves as a second sub-pixel unit SPX-2, and the blue sub-pixel B13 serves as a first sub-pixel unit SPX-1. The sub-pixels in the remaining rows can be deduced in the same manner and are not described in detail here. Furthermore, in the first column of sub-pixels, the red sub-pixel R11 serves as a first sub-pixel unit SPX-1, the red sub-pixel R21 serves as a second sub-pixel unit SPX-2, the red sub-pixel R31 serves as a first sub-pixel unit SPX-1, the red sub-pixel R41 serves as a second sub-pixel unit SPX-2, the red sub-pixel R51 serves as a first sub-pixel unit SPX-1, the red sub-pixel R61 serves as a second sub-pixel unit SPX-2, the red sub-pixel R71 serves as a first sub-pixel unit SPX-1, and the red sub-pixel R81 serves as a second sub-pixel unit SPX-2. The same can be said for the sub-pixels in the remaining columns, which will not be described in detail here.

[0104] For example, taking the current original grayscale value as 127, the first target grayscale value as 170, and the second target grayscale value as 40 as an example, Figure 7As shown, in the current display frame F_n, the data voltage corresponding to the grayscale value of 170 can be input to the red sub-pixels R11, R31, R51, R71, R22, R42, R62, R82, R13, R33, R53, R73, the green sub-pixels G21, G41, G61, G81, G12, G32, G52, G72, G23, G43, G63, G83, and the blue sub-pixels B11, B31, B51, B71, B22, B42, B62, B82, B13, B33, B53, B73 respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the grayscale value of 170. In addition, data voltages corresponding to 40 grayscale values ​​can be input to the red sub-pixels R21, R41, R61, R81, R12, R22, R52, R72, R23, R43, R63, R83, green sub-pixels G11, G31, G51, G71, G22, G42, G62, G82, G13, G33, G53, G73, and blue sub-pixels B21, B41, B61, B81, B12, B22, B52, B72, B23, B43, B63, B83, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the 40 grayscale values. Since the brightness corresponding to the grayscale value of 170 is greater than the brightness corresponding to the grayscale value of 127, and the brightness corresponding to the grayscale value of 40 is less than the brightness corresponding to the grayscale value of 127, the brightness of the two adjacent sub-pixels can be mixed to achieve a brightness of 127 grayscale, so that the mixed brightness displayed in the area can be the brightness of 127 grayscale, thereby improving color deviation.

[0105] S300, in the next display frame of the plurality of consecutive display frames, the first sub-pixel unit SPX-1 in the control area inputs a data voltage corresponding to the second target grayscale value, and the second sub-pixel unit SPX-2 in the control area inputs a data voltage corresponding to the first target grayscale value.

[0106] For example, taking the current original grayscale value as 127, the first target grayscale value as 170, and the second target grayscale value as 40 as an example, Figure 8As shown, in the next display frame F_n+1, the data voltage corresponding to the grayscale value of 40 can be input to the red sub-pixels R11, R31, R51, R71, R22, R42, R62, R82, R13, R33, R53, R73, the green sub-pixels G21, G41, G61, G81, G12, G32, G52, G72, G23, G43, G63, G83, and the blue sub-pixels B11, B31, B51, B71, B22, B42, B62, B82, B13, B33, B53, B73, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the grayscale value of 40. In addition, data voltages corresponding to a grayscale value of 170 can be input to the red sub-pixels R21, R41, R61, R81, R12, R22, R52, R72, R23, R43, R63, R83, the green sub-pixels G11, G31, G51, G71, G22, G42, G62, G82, G13, G33, G53, G73, and the blue sub-pixels B21, B41, B61, B81, B12, B22, B52, B72, B23, B43, B63, B83, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the grayscale value of 170. Since the brightness corresponding to the grayscale value of 170 is greater than the brightness corresponding to the grayscale value of 127, and the brightness corresponding to the grayscale value of 40 is less than the brightness corresponding to the grayscale value of 127, the brightness of the two adjacent sub-pixels can be mixed to achieve a brightness of 127 grayscale, so that the mixed brightness displayed in the area can be the brightness of 127 grayscale, thereby improving color deviation.

[0107] In the embodiment of the present disclosure, the first target grayscale value and the second target grayscale value corresponding to the sub-pixels in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 in the display frame F_n+2 are substantially the same as the first target grayscale value and the second target grayscale value corresponding to the sub-pixels in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 in the display frame F_n. The first target grayscale value and the second target grayscale value corresponding to the sub-pixels in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 in the display frame F_n+3 are substantially the same as the first target grayscale value and the second target grayscale value corresponding to the sub-pixels in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 in the display frame F_n+1. The same can be said for the remaining display frames, which will not be described in detail here.

[0108] In an embodiment of the present disclosure, the timing controller may, when the current original grayscale values ​​corresponding to sub-pixels in the same region are the same in a plurality of consecutive display frames, convert the current original grayscale value into a first target grayscale value and a second target grayscale value, and output the first target grayscale value and the second target grayscale value to the source driver circuit. After the source driver circuit receives the first target grayscale value and the second target grayscale value output by the timing controller, the control circuit may, in a current display frame of the plurality of consecutive display frames, input a data voltage corresponding to the first target grayscale value to the first sub-pixel unit SPX-1 in the control region, and input a data voltage corresponding to the second target grayscale value to the second sub-pixel unit SPX-2 in the control region. Furthermore, in a next display frame of the plurality of consecutive display frames, the control circuit may input a data voltage corresponding to the second target grayscale value to the first sub-pixel unit SPX-1 in the control region, and input a data voltage corresponding to the first target grayscale value to the second sub-pixel unit SPX-2 in the control region.

[0109] In an embodiment of the present disclosure, the timing controller can directly output the current original grayscale value corresponding to the sub-pixel outside the region to the source driver circuit in multiple consecutive display frames. After the source driver circuit receives the current original grayscale value output by the timing controller, it can control the sub-pixels outside the region to input a data voltage corresponding to the current original grayscale value in the current display frame of the multiple consecutive display frames. Furthermore, in the next display frame of the multiple consecutive display frames, it can control the sub-pixels outside the region to input a data voltage corresponding to the current original grayscale value.

[0110] For example, the timing controller may pre-determine whether the current original grayscale values ​​corresponding to the sub-pixels in the same region are within the grayscale range in a plurality of consecutive display frames. If so, that is, the current original grayscale values ​​corresponding to the sub-pixels in the same region are within the grayscale range, the current original grayscale values ​​are converted into a first target grayscale value and a second target grayscale value, and the first target grayscale value and the second target grayscale value are output to the source driver circuit, so that the source driver circuit can control the first sub-pixel unit SPX-1 in the region to input a data voltage corresponding to the first target grayscale value, and the second sub-pixel unit SPX-2 in the region to input a data voltage corresponding to the second target grayscale value in the current display frame. Furthermore, in the next display frame, the first sub-pixel unit SPX-1 in the region is controlled to input a data voltage corresponding to the second target grayscale value, and the second sub-pixel unit SPX-2 in the region is controlled to input a data voltage corresponding to the first target grayscale value. If not, that is, the current original grayscale value corresponding to the sub-pixels in the same area is not within the grayscale range, then the human eye will not easily observe the afterimage problem. Therefore, the current original grayscale value corresponding to the sub-pixel is directly output to the source driver circuit, so that after the source driver circuit receives the current original grayscale value output by the timing controller, it can control the sub-pixels in the area except for the current display frame to input the data voltage corresponding to the current original grayscale value. In addition, in the next display frame of the consecutive multiple display frames, the sub-pixels in the area are controlled to input the data voltage corresponding to the current original grayscale value. Optionally, taking 8 bits as an example, the grayscale range can be 311 to 180 grayscale values, including the end points. The human eye will not easily observe and identify mura at grayscale values ​​less than 31 and greater than 180. In this case, the driving method of converting the current original grayscale value to the first target grayscale value and the second target grayscale value can be omitted, which can reduce power consumption.

[0111] In an embodiment of the present disclosure, converting the current original grayscale value into a first target grayscale value and a second target grayscale value may include: converting the current original grayscale value with a default grayscale bit number into a first target grayscale value and a second target grayscale value of a target grayscale bit number. The target grayscale bit number may be equal to the default grayscale bit number. For example, the target grayscale bit number and the default grayscale bit number may both be 8 bits, 10 bits, or 12 bits, etc. Taking 8 bits as an example, the 8-bit 127 grayscale value may be converted into an 8-bit 170 grayscale value and a 40 grayscale value. At this time, the 170 grayscale and the 40 grayscale are mixed to form a 127 grayscale. Compared with the 127 grayscale, the 170 grayscale and the 40 grayscale are grayscales that are not sensitive to voltage, and it is not easy for the user to observe afterimages. Alternatively, the target grayscale bit number may be greater than the default grayscale bit number. For example, the target grayscale bit number is 10 bits, and the default grayscale bit number is 8 bits. Taking 8-bit as an example, the 127 grayscale values ​​of 8-bit can be converted to 680 grayscale values ​​and 160 grayscale values ​​of 10-bit.

[0112] In an embodiment of the present disclosure, a first lookup table can be stored in a timing controller. The first lookup table can include: multiple different original grayscale values ​​corresponding to a default grayscale bit count, multiple different first target grayscale values ​​corresponding to a target grayscale bit count, and multiple different second target grayscale values. Furthermore, in the first lookup table, each original grayscale value corresponds to a first target grayscale value and a second target grayscale value. Exemplarily, the original grayscale values ​​in the first lookup table are each grayscale value corresponding to the default grayscale bit count. For example, when the default grayscale bit count is 8 bits, the first lookup table contains each grayscale value from 0 to 255, and a first target grayscale value and a second target grayscale value corresponding to each grayscale value from 0 to 255. For example, taking the case where both the target grayscale bit count and the default grayscale bit count are 8 bits, Table 1 illustrates the first target grayscale value L_H and the second target grayscale value L_L corresponding to grayscale values ​​from 125 to 130. It should be noted that the specific grayscale values ​​illustrated in Table 1 are for illustrative purposes only. In actual applications, these values ​​can be determined based on actual application requirements and are not limited here.

[0113]

[0114]

[0115] Table 1

[0116] In the embodiment of the present disclosure, the first lookup table includes the first target grayscale value and the second target grayscale value corresponding to each color sub-pixel. For example, the first lookup table includes the first target grayscale value and the second target grayscale value corresponding to each original grayscale value of the red sub-pixel, the first target grayscale value and the second target grayscale value corresponding to the green sub-pixel, and the first target grayscale value and the second target grayscale value corresponding to the blue sub-pixel. For example, taking the target grayscale bit number and the default grayscale bit number as 8 bits as an example, Table 2 illustrates the first target grayscale value LR_H and the second target grayscale value LR_L of the red sub-pixel, the first target grayscale value LG_H and the second target grayscale value LG_L of the green sub-pixel, and the first target grayscale value LB_H and the second target grayscale value LB_L of the blue sub-pixel corresponding to the grayscale values ​​of 125 to 130. It should be noted that the specific numerical values ​​of the grayscale values ​​illustrated in Table 1 are only examples. In actual applications, they can be determined according to the needs of the actual application and are not limited here.

[0117] Original grayscale value LR_H LG_H LB_H LR_L LG_L LB_L 125 168 168 168 38 38 38 126 169 169 169 39 39 39 127 170 170 170 40 40 40 128 171 171 171 41 41 41 129 172 172 172 42 42 42 130 173 173 173 43 43 43

[0118] Table 2

[0119] In an embodiment of the present disclosure, converting a current original grayscale value having a default number of grayscale bits into a first target grayscale value and a second target grayscale value having a target number of grayscale bits may include: determining, based on the current original grayscale value, the first target grayscale value and the second target grayscale value corresponding to the current original grayscale value from a pre-stored first lookup table. For example, in conjunction with Table 2, when the current original grayscale value is a grayscale value of 127, the first target grayscale value corresponding to the red sub-pixel, the first target grayscale value corresponding to the green sub-pixel, the first target grayscale value corresponding to the blue sub-pixel, the second target grayscale value corresponding to the red sub-pixel, the second target grayscale value corresponding to the green sub-pixel, and the second target grayscale value corresponding to the blue sub-pixel are determined to be 40 grayscale values, 40 grayscale values, and 40 grayscale values, respectively. In this way, a data voltage corresponding to a grayscale value of 170 can be input to the red sub-pixel in the first sub-pixel unit SPX-1, a data voltage corresponding to a grayscale value of 170 can be input to the green sub-pixel in the first sub-pixel unit SPX-1, a data voltage corresponding to a grayscale value of 170 can be input to the blue sub-pixel in the first sub-pixel unit SPX-1, a data voltage corresponding to a grayscale value of 40 can be input to the red sub-pixel in the second sub-pixel unit SPX-2, a data voltage corresponding to a grayscale value of 40 can be input to the green sub-pixel in the second sub-pixel unit SPX-2, and a data voltage corresponding to a grayscale value of 40 can be input to the blue sub-pixel in the second sub-pixel unit SPX-2.

[0120] In the embodiment of the present disclosure, the display panel can be driven using a frame flipping mode, a column flipping mode, a row flipping mode, and a dot flipping mode. For example, taking frame flipping as an example, in display frame F_n, the data voltage input to each sub-pixel can be made to correspond to a positive polarity. In display frame F_n+1, the data voltage input to each sub-pixel can be made to correspond to a negative polarity. In display frame F_n+2, the data voltage input to each sub-pixel can be made to correspond to a positive polarity. In display frame F_n+3, the data voltage input to each sub-pixel can be made to correspond to a negative polarity. However, for the first sub-pixel unit SPX-1, in display frames F_n and F_n+2 in which the first sub-pixel unit SPX-1 displays a higher brightness, the polarity corresponding to the sub-pixel in the first sub-pixel unit SPX-1 is always positive. In display frames F_n+1 and F_n+3 in which the first sub-pixel unit SPX-1 displays a lower brightness, the polarity corresponding to the sub-pixel in the first sub-pixel unit SPX-1 is always negative. Furthermore, for the second sub-pixel unit SPX-2, in the display frames F_n and F_n+2 in which the first sub-pixel unit displays a lower brightness, the polarity corresponding to the sub-pixel in the second sub-pixel unit SPX-2 is always positive. In the display frames F_n+1 and F_n+3 in which the first sub-pixel unit SPX-1 displays a higher brightness, the polarity corresponding to the sub-pixel in the first sub-pixel unit SPX-1 is always negative. This will cause color deviation due to the polarization of the liquid crystal molecules. In order to avoid color deviation due to the polarization of the liquid crystal molecules, in the embodiment of the present disclosure, in multiple consecutive display frames, the polarity corresponding to the data voltage input to each sub-pixel in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 can be controlled to flip once after an even number of display frames.

[0121] For example, in a plurality of consecutive display frames, the polarity of the data voltage corresponding to each sub-pixel in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 may be controlled to flip once after two display frames. For example, taking the frame flip, the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 each including one sub-pixel as an example, combined with Figure 9As shown, in display frame F_n, the sub-pixels R11 to B12 in the first row and the sub-pixels R21 to B22 in the second row are respectively input with data voltages corresponding to positive polarity. In display frame F_n+1, the sub-pixels R11 to B12 in the first row and the sub-pixels R21 to B22 in the second row are also respectively input with data voltages corresponding to positive polarity. In display frame F_n+2, the sub-pixels R11 to B12 in the first row and the sub-pixels R21 to B22 in the second row are respectively input with data voltages corresponding to negative polarity. In display frame F_n+3, the sub-pixels R11 to B12 in the first row and the sub-pixels R21 to B22 in the second row are also respectively input with data voltages corresponding to negative polarity. In display frame F_n+4, the sub-pixels R11 to B12 in the first row and the sub-pixels R21 to B22 in the second row are respectively input with data voltages corresponding to positive polarity. In display frame F_n+5, sub-pixels R11 to B12 in the first row and sub-pixels R21 to B22 in the second row also receive data voltages corresponding to positive polarity. In display frame F_n+6, sub-pixels R11 to B12 in the first row and sub-pixels R21 to B22 in the second row also receive data voltages corresponding to negative polarity. In display frame F_n+7, sub-pixels R11 to B12 in the first row and sub-pixels R21 to B22 in the second row also receive data voltages corresponding to negative polarity. The process for the remaining display frames can be deduced in a similar manner and is not further described here.

[0122] For example, in a plurality of consecutive display frames, the polarity of the data voltage input to each subpixel in the first subpixel unit SPX-1 and the second subpixel unit SPX-2 may be reversed once every four display frames. For example, in a frame flip, where the first subpixel unit SPX-1 and the second subpixel unit SPX-2 each include one subpixel, in display frames F_n to F_n+3, the subpixels R11 to B12 in the first row and the subpixels R21 to B22 in the second row are respectively input with data voltages of positive polarity. In display frames F_n+4 to F_n+7, the subpixels R11 to B12 in the first row and the subpixels R21 to B22 in the second row are respectively input with data voltages of negative polarity. In display frames F_n+8 to F_n+11, the subpixels R11 to B12 in the first row and the subpixels R21 to B22 in the second row are respectively input with data voltages of positive polarity. In display frames F_n+12 to F_n+15, the sub-pixels R11 to B12 in the first row and R21 to B22 in the second row are respectively input with corresponding negative polarity data voltages. The process of the remaining display frames can be deduced in the same way and will not be described in detail here.

[0123] It should be noted that in multiple consecutive display frames, the polarity corresponding to the data voltage input to each sub-pixel in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 may be reversed once after 6, 8 or more display frames, which is not limited here.

[0124] The embodiments of the present disclosure provide other display panel driving methods, which are modified from the implementation methods of the above embodiments. The following only describes the differences between this embodiment and the above embodiments, and the similarities are not repeated here.

[0125] In an embodiment of the present disclosure, a second lookup table can be stored in the timing controller. The second lookup table includes: a plurality of different original grayscale values ​​corresponding to the default grayscale bit number, a plurality of different intermediate grayscale values ​​corresponding to the intermediate grayscale bit number, a plurality of different first target grayscale values ​​corresponding to the target grayscale bit number, and a plurality of different second target grayscale values; and, in the second lookup table, one original grayscale value corresponds to one intermediate grayscale value, and one intermediate grayscale value corresponds to one first target grayscale value and one second target grayscale value. Moreover, the number of intermediate grayscale bits of the current intermediate grayscale value is greater than the default grayscale bit number, and the number of intermediate grayscale bits is less than the target grayscale bit number. For example, the default grayscale bit number can be 8 bits, the intermediate grayscale bit number is 10 bits, and the target grayscale bit number is 12 bits. In this way, an 8-bit grayscale value can be first converted into a 10-bit intermediate grayscale value, and then the 10-bit intermediate grayscale value can be converted into a 12-bit first target grayscale value and a second target grayscale value. Then, the 12-bit first target grayscale value and the second target grayscale value are used to control the display brightness of the sub-pixels in the first sub-pixel unit SPX-1 and the sub-pixels in the second sub-pixel unit SPX-2, so that after mixing the display brightness of the sub-pixels in the first sub-pixel unit SPX-1 and the sub-pixel in the second sub-pixel unit SPX-2, the brightness of the 8-bit 127 grayscale value is displayed. If the 8-bit grayscale value is directly used to mix the brightness of the 8-bit 127 grayscale value, the mixed brightness will be relatively rough. Since the 12-bit grayscale value distinguishes brightness more delicately, using the 12-bit grayscale value to mix the 8-bit brightness will make the mixed brightness more delicate and closer to the 8-bit brightness.

[0126] Exemplarily, the original grayscale values ​​in the second lookup table are the grayscale values ​​of the default grayscale bit number. For example, when the default grayscale bit number is 8 bits, the second lookup table has each grayscale value in the grayscale value range of 0 to 255, as well as an intermediate grayscale value corresponding to the grayscale values ​​0 to 255, a first target grayscale value, and a second target grayscale value. For example, taking the default grayscale bit number of 8 bits, the intermediate grayscale bit number of 10 bits, and the target grayscale bit number of 12 bits as an example, Table 3 illustrates the intermediate grayscale value L_Z, the first target grayscale value L_H, and the second target grayscale value L_L corresponding to the grayscale values ​​125 to 130. It should be noted that the specific numerical values ​​of the grayscale values ​​illustrated in Table 3 are only examples. In actual applications, they can be determined according to the needs of the actual application and are not limited here.

[0128] Table 3

[0129] In the disclosed embodiment, the second lookup table includes first and second target grayscale values ​​corresponding to various color sub-pixels. For example, the second lookup table includes first and second target grayscale values ​​corresponding to red sub-pixels, green sub-pixels, and blue sub-pixels corresponding to respective original grayscale values. For example, taking the default grayscale bit count of 8 bits, the intermediate grayscale bit count of 10 bits, and the target grayscale bit count of 12 bits as an example, Table 4 illustrates the intermediate grayscale value L_Z corresponding to grayscale values ​​125 to 130, the first and second target grayscale values ​​LR_H and LR_L of the red sub-pixel, the first and second target grayscale values ​​LG_H and LG_L of the green sub-pixel, and the first and second target grayscale values ​​LB_H and LB_L of the blue sub-pixel. It should be noted that the specific grayscale values ​​illustrated in Table 4 are merely illustrative.

[0130] In practical applications, it can be determined according to the needs of the practical application and is not limited here.

[0132] Table 4

[0133] In an embodiment of the present disclosure, converting a current raw grayscale value having a default number of grayscale bits into a first target grayscale value and a second target grayscale value having a target number of grayscale bits may include: determining, based on the current raw grayscale value, a current intermediate grayscale value corresponding to the current raw grayscale value from a pre-stored second lookup table. Thereafter, based on the current intermediate grayscale value, determining, from the second lookup table, the first target grayscale value and the second target grayscale value corresponding to the current intermediate grayscale value. For example, with reference to Table 4, if the current raw grayscale value is a grayscale value of 127, the current intermediate grayscale value may be determined to be a grayscale value of 508 by searching the second lookup table. Then, according to the grayscale value of 508, it is determined that the first target grayscale value corresponding to the red sub-pixel is 2734 grayscale value, and the second target grayscale value is 641 grayscale value. The first target grayscale value corresponding to the green sub-pixel is 2734 grayscale value, and the second target grayscale value is 641 grayscale value. The first target grayscale value corresponding to the blue sub-pixel is 2734 grayscale value, and the second target grayscale value is 641 grayscale value. In this way, the data voltage corresponding to the grayscale value of 2734 can be input to the red sub-pixel in the first sub-pixel unit SPX-1, and the data voltage corresponding to the grayscale value of 2734 can be input to the first sub-pixel unit SPX-1. The green sub-pixel in unit SPX-1 inputs a data voltage corresponding to a grayscale value of 2734, the blue sub-pixel in the first sub-pixel unit SPX-1 inputs a data voltage corresponding to a grayscale value of 2734, the red sub-pixel in the second sub-pixel unit SPX-2 inputs a data voltage corresponding to a grayscale value of 641, the green sub-pixel in the second sub-pixel unit SPX-2 inputs a data voltage corresponding to a grayscale value of 641, and the blue sub-pixel in the second sub-pixel unit SPX-2 inputs a data voltage corresponding to a grayscale value of 641.

[0134] For example, in combination with Table 4, taking the current original grayscale value as 127, the first target grayscale value as 2734, and the second target grayscale value as 641 as an example, Figure 9As shown, in the current display frame F_n, data voltages corresponding to a grayscale value of 2734 can be input to the red sub-pixels R11 and R22, the green sub-pixels G21 and G12, and the blue sub-pixels B11 and B22, respectively. This allows these sub-pixels to display a brightness corresponding to the grayscale value of 2734. Furthermore, data voltages corresponding to a grayscale value of 641 can be input to the red sub-pixels R21 and R12, the green sub-pixels G11 and G22, and the blue sub-pixels B21 and B12, respectively. This allows these sub-pixels to display a brightness corresponding to the grayscale value of 641. Since 2734 / 16 is approximately a grayscale value of 170 in 8-bit, and 641 / 16 is approximately a grayscale value of 40, the sub-pixel inputting a grayscale value of 2734 can display a brightness corresponding to a grayscale value of 170, and the sub-pixel inputting a grayscale value of 641 can display a brightness corresponding to a grayscale value of 40. Furthermore, in the current display frame F_n+1, data voltages corresponding to the grayscale value of 641 can be input to the red sub-pixels R11 and R22, the green sub-pixels G21 and G12, and the blue sub-pixels B11 and B22, respectively. This allows these sub-pixels to display a brightness corresponding to the grayscale value of 641. Furthermore, data voltages corresponding to the grayscale value of 2734 can be input to the red sub-pixels R21 and R12, the green sub-pixels G11 and G22, and the blue sub-pixels B21 and B12, respectively. This allows these sub-pixels to display a brightness corresponding to the grayscale value of 2734. Since 2734 / 16 is approximately the grayscale value of 170 in 8-bit, and 641 / 16 is approximately the grayscale value of 40, the sub-pixel inputting the grayscale value of 2734 can display a brightness corresponding to the grayscale value of 170, and the sub-pixel inputting the grayscale value of 641 can display a brightness corresponding to the grayscale value of 40. Since the brightness corresponding to the grayscale value of 170 is greater than the brightness corresponding to the grayscale value of 127, and the brightness corresponding to the grayscale value of 40 is less than the brightness corresponding to the grayscale value of 127, the brightness of the two adjacent sub-pixels can be mixed to achieve a brightness of 127 grayscale, so that the mixed brightness displayed in the area can be the brightness of 127 grayscale, thereby improving color deviation.

[0135] The present disclosure provides further display panel driving methods, which are modified from the above embodiments. The following only describes the differences between this embodiment and the above embodiments, and the similarities are not repeated here.

[0136] In the embodiment of the present disclosure, in the row direction X and the column direction F of the sub-pixels, the sub-pixel units are repeatedly arranged in the order of the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2. Figure 10 and Figure 11As shown, a first subpixel unit SPX-1 may include two adjacent subpixels along the row direction X, and a second subpixel unit SPX-2 may include two adjacent subpixels along the row direction X. For example, in the first row, red subpixel R11 and green subpixel G11 form a first subpixel unit SPX-1. Blue subpixel B11 and red subpixel R12 form a second subpixel unit SPX-2. Green subpixel G12 and blue subpixel B12 form a first subpixel unit SPX-1. Red subpixel R13 and green subpixel G13 form a second subpixel unit SPX-2. In the second row, red subpixel R21 and green subpixel G21 form a second subpixel unit SPX-2. Blue subpixel B21 and red subpixel R22 form a first subpixel unit SPX-1. Green subpixel G22 and blue subpixel B22 form a second subpixel unit SPX-2. Red subpixel R23 and green subpixel G23 form a third subpixel unit. The same applies to the remaining rows and is not further described here.

[0137] For example, in combination with Table 4, taking the current original grayscale value as 127, the first target grayscale value as 2734, and the second target grayscale value as 641 as an example, Figure 10 and Figure 11As shown, in the current display frame F_n, data voltages corresponding to grayscale values ​​of 2734 can be input to the red sub-pixels R11, R31, R51, R22, R42, R62, R23, R43, R63, the green sub-pixels G11, G31, G51, G12, G32, G52, G23, G43, G63, and the blue sub-pixels B21, B41, B61, B12, B32, B52, so that the brightness displayed by these sub-pixels is the brightness corresponding to the grayscale value of 2734. Furthermore, data voltages corresponding to the grayscale value of 641 can be input to the red sub-pixels R21, R41, R61, R12, R32, R52, R13, R33, and R53; the green sub-pixels G21, G41, G61, G22, G42, G62, G13, G33, and G53; and the blue sub-pixels B11, B31, B51, B22, B42, and B62, respectively. This allows these sub-pixels to display a brightness corresponding to the grayscale value of 641. Since 2734 / 16 is approximately the grayscale value of 170 for 8 bits and 641 / 16 is approximately the grayscale value of 40, the sub-pixel with the grayscale value of 2734 can display a brightness corresponding to the grayscale value of 170, and the sub-pixel with the grayscale value of 641 can display a brightness corresponding to the grayscale value of 40. In addition, in the current display frame F_n+1, data voltages corresponding to grayscale values ​​of 641 can be input to the red sub-pixels R11, R31, R51, R22, R42, R62, R23, R43, R63, the green sub-pixels G11, G31, G51, G12, G32, G52, G23, G43, G63, and the blue sub-pixels B21, B41, B61, B12, B32, B52, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the grayscale value of 641. Furthermore, data voltages corresponding to a grayscale value of 2734 can be input to the red sub-pixels R21, R41, R61, R12, R32, R52, R13, R33, and R53; the green sub-pixels G21, G41, G61, G22, G42, G62, G13, G33, and G53; and the blue sub-pixels B11, B31, B51, B22, B42, and B62, respectively. This allows these sub-pixels to display a brightness corresponding to a grayscale value of 2734. Since 2734 / 16 is approximately a grayscale value of 170 for 8 bits and 641 / 16 is approximately a grayscale value of 40, the sub-pixel with an input grayscale value of 2734 can display a brightness corresponding to a grayscale value of 170, and the sub-pixel with an input grayscale value of 641 can display a brightness corresponding to a grayscale value of 40.Since the brightness corresponding to the grayscale value of 170 is greater than that corresponding to the grayscale value of 127, and the brightness corresponding to the grayscale value of 40 is less than that corresponding to the grayscale value of 127, the brightness of two adjacent sub-pixels can be mixed to achieve the brightness of the grayscale value of 127. Therefore, the mixed brightness of the area displayed is the brightness of the grayscale value of 127, which can improve color cast and vertical stripes.

[0138] It should be noted that the first sub-pixel unit SPX-1 may also include three, four, five or more sub-pixels adjacent along the row direction X, and the second sub-pixel unit SPX-2 may include three, four, five or more sub-pixels adjacent along the row direction X, which is not limited here.

[0139] The present disclosure provides further display panel driving methods, which are modified from the above embodiments. The following only describes the differences between this embodiment and the above embodiments, and the similarities are not repeated here.

[0140] In the embodiment of the present disclosure, in the row direction X and the column direction F of the sub-pixels, the sub-pixel units are repeatedly arranged in the order of the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2. Figure 12 and Figure 13 As shown, the first sub-pixel unit SPX-1 includes two sub-pixels adjacent to each other along the column direction F, and the second sub-pixel unit SPX-2 includes two sub-pixels adjacent to each other along the column direction F. For example, in the first column, the red sub-pixels R11 and R21 serve as a first sub-pixel unit SPX-1, the red sub-pixels R31 and R41 serve as a second sub-pixel unit SPX-2, and the red sub-pixels R51 and R61 serve as a first sub-pixel unit SPX-1. In the second column, the green sub-pixels G11 and G21 serve as a second sub-pixel unit SPX-2, the green sub-pixels G31 and G41 serve as a first sub-pixel unit SPX-1, and the green sub-pixels G51 and G61 serve as a second sub-pixel unit SPX-2. The same applies to the remaining columns and is not described in detail here.

[0141] For example, in combination with Table 4, taking the current original grayscale value as 127, the first target grayscale value as 2734, and the second target grayscale value as 641 as an example, Figure 12 and Figure 13As shown, in the current display frame F_n, data voltages corresponding to grayscale values ​​of 2734 can be input to the red sub-pixels R11, R21, R51, R61, R32, R42, R13, R23, R53, R63, the green sub-pixels G31, G41, G12, G22, G52, G62, G33, G43, and the blue sub-pixels B11, B21, B51, B61, B32, B42, respectively, so that the brightness displayed by these sub-pixels is the brightness corresponding to the grayscale value of 2734. Furthermore, data voltages corresponding to the grayscale value of 641 can be input to the red sub-pixels R31, R41, R12, R22, R52, R62, R33, and R43; the green sub-pixels G11, G21, G51, G61, G32, G42, G13, G23, G53, and G63; and the blue sub-pixels B31, B41, B12, B52, and B62, respectively. This allows these sub-pixels to display a brightness corresponding to the grayscale value of 641. Since 2734 / 16 is approximately the grayscale value of 170 for 8 bits and 641 / 16 is approximately the grayscale value of 40, the sub-pixel with the grayscale value of 2734 can display a brightness corresponding to the grayscale value of 170, and the sub-pixel with the grayscale value of 641 can display a brightness corresponding to the grayscale value of 40. In addition, in the current display frame F_n+1, data voltages corresponding to grayscale values ​​of 641 can be input to the red sub-pixels R11, R21, R51, R61, R32, R42, R13, R23, R53, R63, the green sub-pixels G31, G41, G12, G22, G52, G62, G33, G43, and the blue sub-pixels B11, B21, B51, B61, B32, B42, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the grayscale value of 641. Furthermore, data voltages corresponding to a grayscale value of 2734 can be input to the red sub-pixels R31, R41, R12, R22, R52, R62, R33, and R43; the green sub-pixels G11, G21, G51, G61, G32, G42, G13, G23, G53, and G63; and the blue sub-pixels B31, B41, B12, B52, and B62, respectively. This allows these sub-pixels to display a brightness corresponding to a grayscale value of 2734. Since 2734 / 16 is approximately a grayscale value of 170 for 8 bits and 641 / 16 is approximately a grayscale value of 40, the sub-pixel with an input grayscale value of 2734 can display a brightness corresponding to a grayscale value of 170, and the sub-pixel with an input grayscale value of 641 can display a brightness corresponding to a grayscale value of 40.Since the brightness corresponding to the grayscale value of 170 is greater than that corresponding to the grayscale value of 127, and the brightness corresponding to the grayscale value of 40 is less than that corresponding to the grayscale value of 127, the brightness of two adjacent sub-pixels can be mixed to achieve the brightness of the grayscale value of 127. Therefore, the mixed brightness of the area displayed is the brightness of the grayscale value of 127, which can improve color cast and horizontal stripes.

[0142] It should be noted that the first sub-pixel unit SPX-1 may also include three, four, five or more sub-pixels adjacent along the column direction F, and the second sub-pixel unit SPX-2 may include three, four, five or more sub-pixels adjacent along the column direction F, which is not limited here.

[0143] The present disclosure provides further display panel driving methods, which are modified from the above embodiments. The following only describes the differences between this embodiment and the above embodiments, and the similarities are not repeated here.

[0144] In the embodiment of the present disclosure, in the row direction X and the column direction F of the sub-pixels, the sub-pixel units are repeatedly arranged in the order of the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2. Figure 14 and Figure 15 As shown, the first sub-pixel unit SPX-1 includes two rows and two columns of sub-pixels, and the second sub-pixel unit SPX-2 includes two rows and two columns of sub-pixels. For example, the red sub-pixels R11 and R21 and the green sub-pixels G11 and G21 can form a first sub-pixel unit SPX-1. The blue sub-pixels B11 and B21 and the red sub-pixels R12 and R22 can form a second sub-pixel unit SPX-2. The green sub-pixels G12 and G22 and the blue sub-pixels B12 and B22 can form a first sub-pixel unit SPX-1. The red sub-pixels R13 and R23 and the green sub-pixels G13 and G23 can form a second sub-pixel unit SPX-2. The red sub-pixels R31 and R41 and the green sub-pixels G31 and G41 can form a second sub-pixel unit SPX-2. The red sub-pixels R51 and R61 and the green sub-pixels G51 and G61 can form a first sub-pixel unit SPX-1. The same applies to the remaining rows, which are not further described here.

[0145] For example, in combination with Table 4, taking the current original grayscale value as 127, the first target grayscale value as 2734, and the second target grayscale value as 641 as an example, Figure 14 and Figure 15As shown, in the current display frame F_n, data voltages corresponding to grayscale values ​​of 2734 can be input to the red sub-pixels R11, R21, R51, R61, R32, R42, R33, R43, the green sub-pixels G11, G21, G51, G61, G12, G22, G52, G62, G33, G43, and the blue sub-pixels B31, B12, B22, B52, B62, respectively, so that the brightness displayed by these sub-pixels is the brightness corresponding to the grayscale value of 2734. Furthermore, data voltages corresponding to the grayscale value of 641 can be input to the red sub-pixels R11, R21, R51, R61, R32, R42, R33, and R43; the green sub-pixels G11, G21, G51, G61, G12, G22, G52, G62, G33, and G43; and the blue sub-pixels B31, B12, B22, B52, and B62, respectively. This allows these sub-pixels to display a brightness corresponding to the grayscale value of 641. Since 2734 / 16 is approximately the grayscale value of 170 in 8-bit and 641 / 16 is approximately the grayscale value of 40, the sub-pixel with the grayscale value of 2734 can display a brightness corresponding to the grayscale value of 170, and the sub-pixel with the grayscale value of 641 can display a brightness corresponding to the grayscale value of 40. In addition, in the current display frame F_n+1, data voltages corresponding to grayscale values ​​of 641 can be input to the red sub-pixels R11, R31, R51, R22, R42, R62, R23, R43, R63, the green sub-pixels G11, G31, G51, G12, G32, G52, G23, G43, G63, and the blue sub-pixels B21, B41, B61, B12, B32, B52, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the grayscale value of 641. Furthermore, data voltages corresponding to a grayscale value of 2734 can be input to the red sub-pixels R21, R41, R61, R12, R32, R52, R13, R33, and R53; the green sub-pixels G21, G41, G61, G22, G42, G62, G13, G33, and G53; and the blue sub-pixels B11, B31, B51, B22, B42, and B62, respectively. This allows these sub-pixels to display a brightness corresponding to a grayscale value of 2734. Since 2734 / 16 is approximately a grayscale value of 170 for 8 bits and 641 / 16 is approximately a grayscale value of 40, the sub-pixel with an input grayscale value of 2734 can display a brightness corresponding to a grayscale value of 170, and the sub-pixel with an input grayscale value of 641 can display a brightness corresponding to a grayscale value of 40.Since the brightness corresponding to the grayscale value of 170 is greater than that corresponding to the grayscale value of 127, and the brightness corresponding to the grayscale value of 40 is less than that corresponding to the grayscale value of 127, the brightness of two adjacent sub-pixels can be mixed to achieve the brightness of the grayscale value of 127. Therefore, the mixed brightness of the displayed area can be the brightness of the grayscale value of 127, thereby improving color cast. In addition, this can also reduce the coarseness of the grid.

[0146] It should be noted that N can be 3, 4, 5 or other values, and M can also be 3, 4, 5 or other values, which are not limited here.

[0147] The present disclosure provides further display panel driving methods, which are modified from the above embodiments. The following only describes the differences between this embodiment and the above embodiments, and the similarities are not repeated here.

[0148] In the embodiment of the present disclosure, in the row direction X and the column direction F of the sub-pixels, the sub-pixel unit is repeatedly arranged in the order of the second sub-pixel unit SPX-2, the first sub-pixel unit SPX-1, the first sub-pixel unit SPX-1, and the second sub-pixel unit SPX-2. For example, Figure 16 and Figure 17 As shown, the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 can each include one sub-pixel. For example, in the first row, the red sub-pixel R11 can serve as a first sub-pixel unit SPX-1, the green sub-pixel G11 can serve as a second sub-pixel unit SPX-2, the blue sub-pixel B11 can serve as a second sub-pixel unit SPX-2, the red sub-pixel R12 can serve as a first sub-pixel unit SPX-1, the green sub-pixel G12 can serve as a first sub-pixel unit SPX-1, the blue sub-pixel B12 can serve as a second sub-pixel unit SPX-2, the red sub-pixel R13 can serve as a second sub-pixel unit SPX-2, and the green sub-pixel G13 can serve as a second sub-pixel unit SPX-2. Furthermore, in the first column, the red sub-pixel R11 can serve as a first sub-pixel unit SPX-1, the red sub-pixel R21 can serve as a second sub-pixel unit SPX-2, the red sub-pixel R31 can serve as a second sub-pixel unit SPX-2, the red sub-pixel R41 can serve as a first sub-pixel unit SPX-1, the red sub-pixel R51 can serve as a first sub-pixel unit SPX-1, the red sub-pixel R61 can serve as a second sub-pixel unit SPX-2, the red sub-pixel R71 can serve as a second sub-pixel unit SPX-2, and the red sub-pixel R81 can serve as a first sub-pixel unit SPX-1. The rest can be deduced accordingly and will not be elaborated on here.

[0149] For example, in combination with Table 4, taking the current original grayscale value as 127, the first target grayscale value as 2734, and the second target grayscale value as 641 as an example, Figure 16 and Figure 17As shown, in the current display frame F_n, data voltages corresponding to grayscale values ​​of 2734 can be input to the red sub-pixels R11, R41, R51, R81, R12, R42, R52, R82, R23, R33, R63, R73, green sub-pixels G21, G31, G61, G71, G12, G42, G52, G82, G13, G43, G53, G83, and blue sub-pixels B21, B31, B61, B71, B22, B32, B62, B72, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the grayscale value of 2734. In addition, data voltages corresponding to 641 grayscale values ​​can be input to the red sub-pixels R21, R31, R61, R71, R22, R32, R62, R72, R13, R43, R53, R83, the green sub-pixels G11, G41, G51, G81, G22, G32, G62, G72, G23, G33, G63, G73, and the blue sub-pixels B11, B41, B51, B81, B12, B42, B52, B82, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the 641 grayscale value. Since 2734 / 16 is approximately the 8-bit grayscale value of 170 and 641 / 16 is approximately the grayscale value of 40, the brightness displayed by the sub-pixel with the input grayscale value of 2734 is approximately the brightness corresponding to the grayscale value of 170, and the brightness displayed by the sub-pixel with the input grayscale value of 641 is approximately the brightness corresponding to the grayscale value of 40. In addition, in the current display frame F_n+1, data voltages corresponding to 641 grayscale values ​​can be input to the red sub-pixels R11, R41, R51, R81, R12, R42, R52, R82, R23, R33, R63, R73, the green sub-pixels G21, G31, G61, G71, G12, G42, G52, G82, G13, G43, G53, G83, and the blue sub-pixels B21, B31, B61, B71, B22, B32, B62, B72, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the 641 grayscale value. In addition, data voltages corresponding to grayscale values ​​of 2734 can be input to the red sub-pixels R21, R31, R61, R71, R22, R32, R62, R72, R13, R43, R53, R83, the green sub-pixels G11, G41, G51, G81, G22, G32, G62, G72, G23, G33, G63, G73, and the blue sub-pixels B11, B41, B51, B81, B12, B42, B52, B82, respectively, so that the brightness displayed by these sub-pixels can be the brightness corresponding to the grayscale value of 2734.Since 2734 / 16 is approximately the 8-bit grayscale value of 170, and 641 / 16 is approximately the grayscale value of 40, the sub-pixel inputting the grayscale value of 2734 can display a brightness roughly corresponding to the brightness of the grayscale value of 170, and the sub-pixel inputting the grayscale value of 641 can display a brightness roughly corresponding to the brightness of the grayscale value of 40. Since the brightness corresponding to the grayscale value of 170 is greater than the brightness corresponding to the grayscale value of 127, and the brightness corresponding to the grayscale value of 40 is less than the brightness corresponding to the grayscale value of 127, the brightness of two adjacent sub-pixels can be mixed to achieve a brightness of the grayscale value of 127. This allows the mixed brightness of the area to be displayed at the brightness of the grayscale value of 127, thereby improving color cast. This can also reduce vertical streaks.

Alternatively, the first sub-pixel unit SPX-1 may also include two, three, four, five, or more sub-pixels that are adjacent along the column direction F.
