[0112] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0113] In the related art, the liquid crystal display panel of the HADS (High aperture advanced super dimensional switching) series product is extremely prone to polarization to cause pixel voltage imbalance for a special pattern picture, such as a 1V1H picture (also referred to as a skip1dot picture). The best pixel common voltage V com is offset, which finally leads to the flicker picture defect phenomenon when the display panel switches from the normally displayed special pattern picture to other pictures.

[0114] Therefore, the embodiments of the present application propose a driving method of a liquid crystal display panel, Figure 1 a driving method flowchart of a liquid crystal display panel is shown, as shown in Figure 1 includes the following steps:

[0115] S101, obtaining an initial common voltage of a first picture.

[0116] The initial common voltage of the first image is obtained. The initial common voltage is the voltage applied to the common electrode of the liquid crystal display panel when the first image is displayed without flickering in the first state.

[0117] S102. Obtain the real-time common voltage, which includes: the first common voltage of the first screen and / or the second common voltage of the second screen.

[0118] The real-time common voltage is obtained, which includes: the first common voltage of the first screen and / or the second common voltage of the second screen. The first common voltage is the voltage applied to the common electrode when the liquid crystal display panel displays the first screen without flickering in the second state, and the second common voltage is the voltage applied to the common electrode when the liquid crystal display panel displays the second screen without flickering in the second state.

[0119] S103. Adjust the grayscale voltage of the target image based on the initial common voltage and the real-time common voltage.

[0120] Based on the initial common voltage and the real-time common voltage, the grayscale voltage of the target image is adjusted. The liquid crystal display panel includes a first sub-pixel and a second sub-pixel. One of the first sub-pixel and the second sub-pixel is lit up in the first image and displays the first grayscale, and the other is lit up in the second image and displays the first grayscale. The electric field polarities of the first sub-pixel and the second sub-pixel are opposite.

[0121] In this embodiment, the first screen is a screen with a special pattern displayed on a liquid crystal display panel. For example, the screen with a special pattern can be a skip1dot pattern where the pixel structure of the liquid crystal display panel alternates between bright and dark. Figure 2 This diagram illustrates the pixel architecture of an L127-order skip1dot pattern image, as shown below. Figure 2 As shown, the LCD panel displays a cyan image as shown on the left, and its pixel structure is shown on the right. In this pixel structure, only the G sub-pixels and B sub-pixels are lit, and they are alternating between bright and dark. This skip1dot pattern image is prone to polarization during long-term aging. When switching from this skip1dot pattern image to other grayscale images, the LCD panel will generally display a flickering image.

[0122] In the embodiments of the present application, the liquid crystal display panel includes first sub-pixels and second sub-pixels, wherein the first sub-pixels are bright pixel points in a special pattern picture pixel structure displayed by the liquid crystal display panel, and the second sub-pixels are dark pixel points in the special pattern picture pixel structure displayed by the liquid crystal display panel, for example, in the pixel structure of the L127 skip1dot pattern picture shown in Figure 2 The first sub-pixels are L127 bright pixel points, and the second sub-pixels are L0 dark pixel points. It should be noted that the first sub-pixels and the second sub-pixels are determined according to the picture displayed by the liquid crystal display panel. The above example is only a specific scenario for understanding the first sub-pixels and the second sub-pixels, and the pixel points corresponding to the first sub-pixels and the second sub-pixels in other cases can be determined according to actual conditions, which is not limited in the present application.

[0123] In the embodiments of the present application, the initial common voltage is a voltage applied to the common electrode of the liquid crystal display panel when the liquid crystal display panel displays a first picture without flicker in a first state. The first state is a state in which the liquid crystal display panel has not been subjected to aging treatment. Specifically, in the state in which the liquid crystal display panel has not been subjected to aging treatment, the special pattern picture displayed by the liquid crystal display panel is adjusted to a state in which the picture has no flicker (the flicker value is the smallest), and the optimal common pixel voltage V com .

[0124] In the embodiments of the present application, the real-time common voltage can be a first common voltage of the first picture, wherein the first common voltage is a voltage applied to the common electrode of the liquid crystal display panel when the liquid crystal display panel displays the first picture without flicker in a second state. The second state is a state in which the liquid crystal display panel produces a flicker phenomenon after aging treatment. Specifically, the special pattern picture displayed by the liquid crystal display panel is subjected to aging treatment until the special pattern picture displayed by the liquid crystal display panel produces a flicker phenomenon when switching to other gray scale pictures, the gray scale displayed by the first sub-pixels and the second sub-pixels in the first picture of the liquid crystal display panel is adjusted, and the optimal common pixel voltage V com1 .

[0125] In the embodiments of the present application, the real-time common voltage can be a second common voltage of a second picture, wherein the second common voltage is a voltage applied to the common electrode when the liquid crystal display panel displays the second picture without flicker in the second state, and the second picture is a picture displayed by the liquid crystal display panel and opposite to the gray scale displayed by the first sub-pixel and the second sub-pixel in the first picture. Specifically, a special pattern picture displayed by the liquid crystal display panel is subjected to aging treatment until the special pattern picture displayed by the liquid crystal display panel flickers when switching to other gray scale pictures, the gray scale displayed by the first sub-pixel and the second sub-pixel in the second picture of the liquid crystal display panel is adjusted, and the optimal common pixel voltage V com2 .

[0126] In the embodiments of the present application, the real-time common voltage can be a first common voltage of a first picture and a second common voltage of a second picture. It should be noted that the gray scale displayed by the first sub-pixel and the second sub-pixel in the first picture is opposite to the gray scale displayed by the first sub-pixel and the second sub-pixel in the second picture, that is, one of the first sub-pixel and the second sub-pixel is lighted and displays a first gray scale in the first picture, and the other is lighted and displays the first gray scale in the second picture, and the electric field polarity of the first sub-pixel and the second sub-pixel is opposite. For example, when the first sub-pixel in the first picture is lighted and displays the first gray scale, other sub-pixels in the first picture are not lighted and display a second gray scale, at this time, the second sub-pixel in the second picture is lighted and displays the first gray scale, and other sub-pixels in the second picture are not lighted and display the second gray scale; when the second sub-pixel in the first picture is lighted and displays the first gray scale, other sub-pixels in the first picture are not lighted and display the second gray scale, at this time, the first sub-pixel in the second picture is lighted and displays the first gray scale, and other sub-pixels in the second picture are not lighted and display the second gray scale.

[0127] wherein the first gray scale is the same as the gray scale of a bright pixel point in a pixel architecture of a skip1dot pattern picture in the first picture, and the second gray scale is a 0 gray scale L0, as shown in a pixel architecture of an L127 gray scale skip1dot pattern picture in the first picture. Figure 2 It should be noted that the above example is only a first gray scale in a specific scenario given for the convenience of understanding, and the first gray scale in other cases can be determined according to actual conditions, which is not limited in the present application.

[0128] Specifically, when acquiring the common voltage, the electric field polarities of the sub-pixels that are lit and displaying the first grayscale in the first and second frames are opposite. As described above, one of the first and second sub-pixels is lit and displays the first grayscale in the first frame, and the other is lit and displays the first grayscale in the second frame. For example, when the first sub-pixel in the first frame is lit and displays the first grayscale, if the electric field polarity of the first sub-pixel in the first frame is negative, then when the second sub-pixel in the second frame is lit and displays the first grayscale, the electric field polarity of the second sub-pixel in the second frame is positive; when the second sub-pixel in the first frame is lit and displays the first grayscale, if the electric field polarity of the second sub-pixel in the first frame is positive, then when the first sub-pixel in the second frame is lit and displays the first grayscale, the electric field polarity of the second sub-pixel in the second frame is negative.

[0129] In this embodiment of the application, after obtaining the initial common voltage V com 1. Implement common voltage (first common voltage V) com1 and / or second common voltage V com2 Then, based on the initial common voltage and the real-time common voltage, the grayscale voltage of the target image is adjusted. The target image is the image with a special pattern currently displayed on the liquid crystal display panel.

[0130] Next, we will introduce the driving method of the liquid crystal display panel in detail, and first analyze the causes of flickering in the liquid crystal display panel:

[0131] When displaying special pattern images on an LCD panel, such as a 1V1H image (also known as a skip1dot image), the first sub-pixel of the LCD panel will generate a DC bias voltage V during the aging process due to the coupling effect of parasitic capacitance and the influence of impurities in the liquid crystal cell. offset This results in unequal voltages between positive and negative frame pixels. Figure 3 This shows a DC bias diagram of a special pattern screen, such as... Figure 3 As shown, in Region 1 and Region 2, a DC bias voltage V is generated. offset This causes the original pixel common voltage V to be lost. com The value was equivalent to DC bias V. offset The offset, thus affecting the original pixel common voltage V com Symmetrical and equal positive frame pixel voltage V + and negative frame pixel voltage V - The voltages are no longer equal, resulting in an imbalance in the actual voltage applied to the pixels. For example... Figure 3As shown, because Area 1 and Area 2 are different gray scales, their capacitive coupling effects are different, resulting in different DC bias effects, and thus flicker occurs when switching from a special pattern picture to other gray scale pictures.

[0132] In addition, due to the effect of DC residual on the liquid crystal display panel, when the display picture of the liquid crystal display panel is switched, the liquid crystal molecules cannot correctly maintain the state required by the design due to the influence of ions, resulting in a difference in display brightness between the ion accumulation area and other areas, which is also a cause of the residual image flicker defect.

[0133] Next, the driving method of the liquid crystal display panel is described in detail.

[0134] In the specific implementation step S101, the polarity of the electric field of the sub-pixel in the liquid crystal display panel is reversed, so that the first sub-pixel or the second sub-pixel in the liquid crystal display panel in the first state displays the first gray scale and displays a single polarity.

[0135] In an alternative embodiment, the first sub-pixel in the liquid crystal display panel in the first state is turned on, so that the first sub-pixel displays the first gray scale, the other sub-pixels of the liquid crystal display panel display the second gray scale (0 gray scale L0), and the polarity of the electric field of the first sub-pixel is adjusted, so that the first sub-pixel displays any one of the positive polarity or the negative polarity. The display picture of the liquid crystal display panel in this state is taken as the first picture.

[0136] In another alternative embodiment, the second sub-pixel of the liquid crystal display panel in the first state is turned on, so that the second sub-pixel displays the first gray scale, the other sub-pixels of the liquid crystal display panel display the second gray scale, and the polarity of the electric field of the second sub-pixel is adjusted, so that the second sub-pixel displays any one of the positive polarity or the negative polarity. The first picture is displayed on the liquid crystal display panel in the first state, and the display picture of the liquid crystal display panel in this state is taken as the first picture.

[0137] It should be noted that the polarity of the electric field of the first sub-pixel or the second sub-pixel displaying the first gray scale in the first picture is a single polarity, which can be a positive polarity or a negative polarity. When obtaining the initial common voltage, the embodiments of the present application only need to ensure that the sub-pixel displaying the first gray scale is in a single polarity.

[0138] Subsequently, in the preset inversion mode of the liquid crystal display panel, the first picture displayed on the liquid crystal display panel in the first state is adjusted to a flicker-free state (minimum flicker value), and the voltage applied to the common electrode at this time is recorded as the initial common voltage V comThe preset inversion mode of the liquid crystal display panel can be column inversion mode, row inversion mode, dot inversion mode, etc. The inversion mode of the liquid crystal display panel can be determined according to actual conditions, and the application does not make any limitation.

[0139] For example, when the liquid crystal display panel displays a special pattern picture of skip1dot only brightening the GB sub-pixel under L127 level, the first picture is a cyan picture. Figure 4 A first picture schematic diagram in a first state of a single polarity of a special pattern picture is shown as follows. Figure 4 As shown on the left side, in an alternative embodiment, the first G sub-pixel in the liquid crystal display panel in the first state is brightened, the first G sub-pixel displays the first gray level L127, the other sub-pixels of the liquid crystal display panel display the second gray level (0 gray level L0), and the electric field polarity of the first sub-pixel is adjusted to make the first sub-pixel display negative polarity. The G negative polarity 1V1H (the G sub-pixel is a pixel structure of one bright and one dark alternately in each row and each column) picture is taken as the first picture. In another alternative embodiment, the second G sub-pixel in the liquid crystal display panel in the first state is brightened, the second G sub-pixel displays the first gray level L127, the other sub-pixels of the liquid crystal display panel display the second gray level (0 gray level L0), and the electric field polarity of the second sub-pixel is adjusted to make the first sub-pixel display positive polarity. The G positive polarity 1V1H picture is taken as the first picture. Subsequently, after the first picture in the first state is adjusted to a non-flickering state in the column inversion mode, the voltage applied to the common electrode at this time is recorded as the initial common voltage.

[0140] Before the step S102 is implemented, the liquid crystal display panel in the first state needs to be subjected to aging treatment. Specifically, the display picture of the liquid crystal display panel in the first state is adjusted to an aging picture, the first sub-pixel of the aging picture displays the first gray level, the second sub-pixel displays the second gray level, the liquid crystal display panel is kept in the aging picture for aging treatment, until the picture displayed by the liquid crystal display panel is switched to another gray level picture, flickering phenomenon occurs, the aging treatment is stopped, and the liquid crystal display panel with the picture causing flickering phenomenon is taken as the liquid crystal display panel in the second state.

[0141] When the step S102 is implemented, the initial common voltage can be the first common voltage of the first picture. Specifically, the electric field polarity of the sub-pixel in the liquid crystal display panel is first controlled to be inverted, so that the first sub-pixel or the second sub-pixel in the liquid crystal display panel in the second state displays the first gray level and displays a single polarity, as the first picture in the second state.

[0142] In an alternative embodiment, the first sub-pixel in the liquid crystal display panel in the second state is lightened, the first sub-pixel displays the first gray scale, other sub-pixels of the liquid crystal display panel display the second gray scale (0 gray scale L0), and the electric field polarity of the first sub-pixel is adjusted to make the first sub-pixel display any one of the positive polarity or the negative polarity, and the display picture of the liquid crystal display panel in this state is taken as the first picture in the second state.

[0143] In another alternative embodiment, the second sub-pixel in the liquid crystal display panel in the second state is lightened, the second sub-pixel displays the first gray scale, other sub-pixels of the liquid crystal display panel display the second gray scale (0 gray scale L0), and the electric field polarity of the second sub-pixel is adjusted to make the second sub-pixel display any one of the positive polarity or the negative polarity, and the display picture of the liquid crystal display panel in this state is taken as the first picture in the second state.

[0144] It should be noted that the electric field polarity of the first sub-pixel or the second sub-pixel displaying the first gray scale in the first picture in the second state is single polarity, which can be positive polarity or negative polarity, and in the acquisition of the first common voltage, the embodiment of the present application only needs to ensure that the sub-pixel displaying the first gray scale in the first picture in the second state is in single polarity, and the polarity is opposite to that of the sub-pixel displaying the first gray scale in the second picture in the second state.

[0145] Subsequently, in the preset inversion mode of the liquid crystal display panel, the first picture displayed on the liquid crystal display panel in the second state is adjusted to a flicker-free state (the flicker value is minimum), and the voltage applied to the common electrode at this time is recorded as the first common voltage V com1 .

[0146] In the implementation of the specific implementation step S102, the common voltage can be the second common voltage of the second picture. Specifically, the electric field polarity of the sub-pixel in the liquid crystal display panel is first controlled to be reversed, so that the first sub-pixel or the second sub-pixel in the liquid crystal display panel in the second state displays the first gray scale and displays single polarity, as the second picture in the second state. Among them, the first sub-pixel and the second sub-pixel in the first picture in the second state, and the first sub-pixel and the second sub-pixel in the second picture in the second state, display opposite gray scales.

[0147] In an alternative embodiment, in the case that the first sub-pixel displays the first gray scale in the first picture in the second state, the second picture in the second state is obtained in the following manner: the first sub-pixel in the liquid crystal display panel in the second state is lightened, the first sub-pixel displays the first gray scale, the other sub-pixels of the liquid crystal display panel display the second gray scale (0 gray scale L0), and the electric field polarity of the first sub-pixel is adjusted so that the first sub-pixel displays one of the positive polarity and the negative polarity which is different from the polarity of the second sub-pixel in the first picture in the second state, and the display picture of the liquid crystal display panel in this state is taken as the second picture in the second state.

[0148] In another alternative embodiment, in the case that the first sub-pixel displays the first gray scale in the first picture in the second state, the second picture in the second state is obtained in the following manner: the second sub-pixel in the liquid crystal display panel in the second state is lightened, the second sub-pixel displays the first gray scale, the other sub-pixels of the liquid crystal display panel display the second gray scale (0 gray scale L0), and the electric field polarity of the second sub-pixel is adjusted so that the second sub-pixel displays one of the positive polarity and the negative polarity which is different from the polarity of the first sub-pixel in the first picture in the second state, and the display picture of the liquid crystal display panel in this state is taken as the second picture in the second state.

[0149] In the second picture in the second state, the electric field polarity of the first sub-pixel or the second sub-pixel displaying the first gray scale is a single polarity, and is opposite to the polarity of the sub-pixel displaying the first gray scale in the first picture in the second state.

[0150] Subsequently, in the preset inversion mode of the liquid crystal display panel, the second picture displayed on the liquid crystal display panel in the second state is adjusted to a flicker-free state (the flicker value is minimum), and the voltage applied to the common electrode at this time is recorded as the second common voltage V com2 .

[0151] In the step S102, the common voltage is also the first common voltage of the first picture and the second common voltage of the second picture. Specifically, the polarity of the electric field of the sub-pixel in the liquid crystal display panel is first controlled to be reversed, so that the first sub-pixel or the second sub-pixel in the liquid crystal display panel in the second state displays the first gray scale and displays a single polarity, to obtain the first picture in the second state and the second picture in the second state. The gray scale displayed by the first sub-pixel and the second sub-pixel in the first picture in the second state is opposite to the gray scale displayed by the first sub-pixel and the second sub-pixel in the second picture in the second state, and the polarity of the electric field of the sub-pixel displaying the first gray scale in the second picture in the second state is opposite to the polarity of the electric field of the sub-pixel displaying the first gray scale in the first picture in the second state. Subsequently, the first picture displayed on the liquid crystal display panel in the second state is adjusted to a flicker-free state in a preset inversion mode of the liquid crystal display panel, and the voltage applied to the common electrode at this time is recorded as the first common voltage V com1 The second picture displayed on the liquid crystal display panel in the second state is adjusted to a flicker-free state, and the voltage applied to the common electrode at this time is recorded as the second common voltage V com2 The specific process of the first common voltage and the second common voltage can be referred to the above-mentioned steps of separately obtaining the first common voltage and separately obtaining the second common voltage, which will not be described here.

[0152] After obtaining the initial common voltage and the real-time common voltage based on the above-mentioned steps S101 and S102, the step S103 is implemented, that is, the gray scale voltage of the target picture is adjusted based on the initial common voltage and the real-time common voltage.

[0153] In the step S103, when the real-time common voltage includes the first common voltage of the first picture and the second common voltage of the second picture, the gray scale voltage of the target picture is adjusted in the following manner: first, the difference between the initial common voltage V com and the first common voltage V com1 of the first picture is calculated to obtain a first voltage adjustment value AV com1 ; then, the difference between the initial common voltage V com and the second common voltage V com2 of the second picture is calculated to obtain a second voltage adjustment value AV com2 .

[0154] Finally, the first voltage adjustment value AV com1 and the second voltage adjustment value AV com2, the gray scale voltage of the target picture is adjusted. The gray scale voltage of the target picture includes a first gray scale voltage and a second gray scale voltage. The first gray scale voltage is the gray scale voltage of the first gray scale of the special pattern picture, for example, the bind point voltage of L127 in the cyan special pattern picture. The second gray scale voltage is the gray scale voltage of the second gray scale of the special pattern picture, for example, the end point voltage of L0 in the cyan special pattern picture. It should be noted that the above examples are only given to facilitate understanding of the first gray scale voltage and the second gray scale voltage in a specific scenario. The first gray scale voltage and the second gray scale voltage in other cases can be determined according to actual conditions, which are not limited in the present application.

[0155] Since the first common voltage used to obtain the first voltage adjustment value and the second common voltage used to obtain the second voltage adjustment value may display the first gray scale to the first sub-pixel or the second sub-pixel during the obtaining process, the first voltage adjustment value and the second voltage adjustment value are used to adjust the gray scale voltages of different target pictures. Specifically, the following two cases are included:

[0156] In the case that the first sub-pixel displays the first gray scale in the first picture and the second sub-pixel displays the first gray scale in the second picture, the first common voltage is used to adjust the first gray scale voltage and the second common voltage is used to adjust the second gray scale voltage. Then, the first gray scale voltage in the target picture is adjusted according to the first voltage adjustment value, and the second gray scale voltage in the target picture is adjusted according to the second voltage adjustment value.

[0157] In the case that the second sub-pixel displays the first gray scale in the first picture and the first sub-pixel displays the first gray scale in the second picture, the first common voltage is used to adjust the second gray scale voltage and the second common voltage is used to adjust the first gray scale voltage. Then, the second gray scale voltage in the target picture is adjusted according to the first voltage adjustment value, and the first gray scale voltage in the target picture is adjusted according to the second voltage adjustment value.

[0158] Specifically, when the real-time common voltage only includes the first common voltage of the first picture, the gray scale voltage of the target picture is adjusted as follows: first, the initial common voltage V com is calculated, and the difference between the initial common voltage V com1 and the first common voltage V com1 is obtained to obtain the first voltage adjustment value AV com1 ; then, the gray scale voltage of the target picture is adjusted according to the first voltage adjustment value AV com1 .

[0159] Since the first common voltage used to obtain the first voltage adjustment value may display the first gray scale for the first sub-pixel or the second sub-pixel during the obtaining process, the first voltage adjustment value is used to adjust the gray scale voltage of the target picture differently. Specifically, the following two cases are included: in the case that the first sub-pixel displays the first gray scale in the first picture, the first common voltage is used to adjust the first gray scale voltage, and the first gray scale voltage is adjusted according to the first voltage adjustment value ΔV com1 , in the case that the second sub-pixel displays the first gray scale in the first picture, the first common voltage is used to adjust the second gray scale voltage, and the second gray scale voltage is adjusted according to the first voltage adjustment value ΔV com1 .

[0160] Specifically, in the case that the real-time common voltage only includes the second common voltage of the second picture, the gray scale voltage of the target picture is adjusted in the following manner: first, the difference between the initial common voltage V com and the second common voltage V com2 of the second picture is calculated to obtain the second voltage adjustment value ΔV com2 ; then the gray scale voltage of the target picture is adjusted according to the second voltage adjustment value ΔV com2 .

[0161] Since the second common voltage used to obtain the second voltage adjustment value may display the first gray scale for the first sub-pixel or the second sub-pixel during the obtaining process, the second voltage adjustment value is used to adjust the gray scale voltage of the target picture differently. Specifically, the following two cases are included: in the case that the first sub-pixel displays the first gray scale in the second picture, the second common voltage is used to adjust the first gray scale voltage, and the first gray scale voltage is adjusted according to the second voltage adjustment value ΔV com2 , in the case that the second sub-pixel displays the first gray scale in the second picture, the second common voltage is used to adjust the second gray scale voltage, and the second gray scale voltage is adjusted according to the second voltage adjustment value ΔV com2 .

[0162] Thus, the adjustment of the gray scale voltage of the target picture based on the first voltage adjustment value and / or the second voltage adjustment value is completed to eliminate the flicker. Figure 5 The adjustment of the gray scale voltage based on the voltage adjustment value is shown in the schematic diagram, as shown in Figure 5 , the gray scale voltage of the positive frame and the negative frame is adjusted based on the first voltage adjustment value and the second voltage adjustment value, so that the adjusted gray scale voltage is symmetrical and equal about the pixel common voltage V com offset by the direct current bias, thereby fundamentally solving the flicker phenomenon when switching to other gray scale pictures.

[0163] However, as described above in the bad reason analysis, the bad phenomenon of flicker residual image has the cause of DC residual in addition to the common voltage offset of the special pattern picture. Therefore, in an alternative embodiment, after adjusting the gray voltage of the target picture, it is necessary to detect again whether the liquid crystal display panel still has flicker when the liquid crystal display panel displays the first picture switching to other gray scale pictures. In the case that there is still flicker, according to the adjustment direction of the voltage adjustment value adopted in the above S103 step, the adjusted gray voltage is fine-tuned multiple times according to the residual elimination increment value. The residual elimination increment value is a voltage adjustment value of a preset size, and the specific residual elimination increment value is set according to the specific situation, which is not limited in the present application.

[0164] Specifically, when the gray voltage of the target picture is adjusted only according to the first voltage adjustment value, and there is still flicker when the liquid crystal display panel displays the first picture switching to other gray scale pictures, the adjusted gray voltage is adjusted according to the residual elimination increment value according to the adjustment direction of the first voltage adjustment value. When the gray voltage of the target picture is adjusted only according to the second voltage adjustment value, and there is still flicker when the liquid crystal display panel displays the first picture switching to other gray scale pictures, the adjusted gray voltage is adjusted according to the residual elimination increment value according to the adjustment direction of the second voltage adjustment value. When the gray voltage of the target picture is adjusted according to the first voltage adjustment value and the second voltage adjustment value, and there is still flicker when the liquid crystal display panel displays the first picture switching to other gray scale pictures, the adjusted gray voltage is adjusted according to the residual elimination increment value according to the adjustment direction of the first voltage adjustment value, and the adjusted gray voltage is adjusted according to the residual elimination increment value according to the adjustment direction of the second voltage adjustment value.

[0165] After each adjustment of the adjusted gray voltage based on the residual elimination increment value, it is tested whether there is flicker when the liquid crystal display panel displays the first picture switching to other gray scale pictures. If there is still flicker, the next adjustment of the residual elimination increment value is performed. If there is no flicker, it is considered that the flicker bad phenomenon is eliminated.

[0166] The application provides a driving method of a liquid crystal display panel, comprising: obtaining an initial common voltage of a first picture, the initial common voltage being a voltage applied to a common electrode of the liquid crystal display panel when the liquid crystal display panel displays the first picture without flicker in a first state; obtaining a real-time common voltage, the real-time common voltage comprising: a first common voltage of the first picture and / or a second common voltage of a second picture, the first common voltage being a voltage applied to the common electrode when the liquid crystal display panel displays the first picture without flicker in a second state, and the second common voltage being a voltage applied to the common electrode when the liquid crystal display panel displays the second picture without flicker in the second state; and adjusting a gray scale voltage of a target picture based on the initial common voltage and the real-time common voltage. The application adjusts the gray scale voltage of the picture by obtaining the real-time common voltage with opposite polarity to calculate the adjustment value of the optimal common voltage, so that the flicker phenomenon caused by the deviation of the optimal pixel common voltage when the liquid crystal display panel switches from displaying a normal special pattern picture to other pictures can be effectively reduced or even eliminated.

[0167] In order for those skilled in the art to more clearly understand the application, the driving method of the liquid crystal display panel described in the application will be described in detail through the embodiments of the application.

[0168] In an alternative embodiment, Figure 6 A skip1dot cyan picture debugging flowchart for simultaneously adjusting the L127 and L0 gray scale voltages is shown, as shown in the following figure. Figure 6 The method comprises the following steps:

[0169] For the liquid crystal display panel of the MNT27QHD HADS product, a Single gate (only one row is scanned at a certain moment) + column inversion mode (+-+-…) architecture is used. The L127 gray scale sub-pixel in the non-warmed liquid crystal display panel is lighted, and the electric field polarity of the first sub-pixel is adjusted, so that the first sub-pixel displays any one of the positive polarity or the negative polarity. The display picture of the liquid crystal display panel in this state is regarded as a first picture, the flicker phenomenon of the first picture is debugged by using a color analyzer CA310, when the first picture is adjusted to the non-flicker state (the flicker value is minimum), the voltage V com = 4.792 V applied to the common electrode at this time is recorded.

[0170] Subsequently, the special cyan pattern image is aged for 10 minutes until it stops flickering. When flickering occurs when switching to the L127 grayscale image, the aging process is stopped. Then, the electric field polarity of the sub-pixels in the liquid crystal display panel under the current image is reversed, so that the first G sub-pixel in the liquid crystal display panel under the current image displays the L127 grayscale and shows a negative polarity, resulting in a G negative polarity image; and the second sub-pixel in the liquid crystal display panel under the current image displays the L127 grayscale and shows a positive polarity, resulting in a G positive polarity image.

[0171] Adjust the G negative polarity screen to a flicker-free state and record the voltage V applied to the common electrode at this time. com1 = 4.832V; Adjust the G positive polarity screen to a flicker-free state and record the voltage V applied to the common electrode at this time. com2 =4.753V.

[0172] Calculate V com1 With V com The difference, ΔV com1 =V com1 -V com =4.832 - 4.792 = 0.04V, ΔV com1 As the first voltage adjustment value; at the same time, calculate V com2 With V com The difference, ΔV com2 =V com2 -V com =4.753-4.792=-0.039V, ΔV com2 As the second voltage adjustment value, the adjustment value of the L127 binding point voltage corresponding to the bright pixels of the target cyan image is ΔV. com1 =0.04V, the adjustment value of the L0 terminal voltage corresponding to the dark pixel of the target cyan image is ΔV. com2 = -0.039V. Adjust the L127 binding point voltage corresponding to the bright pixels and the L0 terminal voltage corresponding to the dark pixels according to the above adjustment value.

[0173] After adjusting the grayscale voltages (the aforementioned binding point voltage and endpoint voltage), and following the adjustment directions of the first and second voltage adjustment values, continue to increase the voltage by 0.01-0.02V for residual flicker correction. This residual flicker correction increment is derived from the voltage range adjustable by one pgamma increment. Repeat the above residual flicker correction steps until the flickering problem on the LCD panel disappears. After final debugging, the final adjustment value of the L127 binding point voltage corresponding to the bright pixels is +0.047V, and the final adjustment value of the L0 endpoint voltage corresponding to the dark pixels is -0.046V.

[0174] In one alternative implementation, Figure 7 This diagram illustrates a flowchart for debugging the skip1dot cyan screen by adjusting only the L0 grayscale voltage. Figure 7 As shown, this embodiment only adjusts the terminal voltage of L0, including the following steps:

[0175] For the LCD panel of the MNT31.5QHD HADS product, a Single-gate (only one row is active at a time) + column inversion mode (+-+-…) architecture is used. The L127 sub-pixel in the unheated LCD panel is illuminated, and the electric field polarity of the first sub-pixel is adjusted to display either positive or negative polarity. The display image of the LCD panel in this state is taken as the first image. The flicker phenomenon of this first image is adjusted using a CA310 color analyzer. When the first image is adjusted to a flicker-free state (flicker value is minimum), the voltage V applied to the common electrode at this time is recorded. com =5.826V.

[0176] Subsequently, the special cyan pattern image is aged for 5 minutes until the special cyan pattern image stops flickering. When flickering occurs when switching to the L127 grayscale image, the aging process is stopped. Then, the electric field polarity of the sub-pixel in the liquid crystal display panel under the current image is reversed, so that the second sub-pixel in the liquid crystal display panel under the current image displays the L127 grayscale and shows positive polarity, thus obtaining a G positive polarity image.

[0177] Adjust the G positive polarity screen to a flicker-free state and record the voltage V applied to the common electrode at this time. com2 =5.756V.

[0178] Calculate V com2 With V com The difference, ΔV com2 =V com2 -V com =5.756-5.826=-0.07V, ΔV com2 As the second voltage adjustment value, the adjustment value of the L0 terminal voltage corresponding to the dark pixels of the target cyan image is ΔV. com2 = -0.07V. Adjust the L0 terminal voltage corresponding to the dark pixel according to the above adjustment value.

[0179] After adjusting the gray scale voltage (the above-mentioned end voltage), and in accordance with the adjustment direction of the second voltage adjustment value, the residual micro-adjustment is continued to be increased by 0.01-0.02V. The above-mentioned residual micro-adjustment step is repeated until the flicker defect of the liquid crystal display panel disappears. After the final adjustment is completed, the final adjustment value of the L0 end voltage corresponding to the dark pixel point is -0.1V.

[0180] In an alternative embodiment, Figure 7 A skip1dot cyan picture adjustment flow chart adjusting only the L0 gray scale voltage is shown as follows, Figure 7 As shown, the embodiment adjusts only the end voltage of L0, including the following steps:

[0181] For the liquid crystal display panel of the MNT23FHD HADS product, the Single gate (only one row is scanned at a certain moment) + column inversion mode (+-+-…) architecture is used. The L127 gray scale sub-pixel in the non-warmed liquid crystal display panel is lit, and the electric field polarity of the first sub-pixel is adjusted so that the first sub-pixel displays any one of the positive polarity or the negative polarity. The display picture of the liquid crystal display panel in this state is taken as the first picture, the flicker phenomenon of the first picture is adjusted using the color analyzer CA310, and when the first picture is adjusted to the non-flicker state (the flicker value is minimum), the voltage V com applied to the common electrode at this time is recorded.

[0182] Subsequently, the special cyan pattern picture is aged for 2h until the special cyan pattern picture does not flicker, and when the flicker phenomenon occurs when switching to the L127 gray scale picture, the aging process is stopped, and then the electric field polarity of the sub-pixel in the liquid crystal display panel under the current picture is controlled to be reversed, so that the second sub-pixel in the liquid crystal display panel under the current picture displays the L127 gray scale and displays the positive polarity, obtaining the G positive polarity picture.

[0183] The G positive polarity picture is adjusted to the non-flicker state, and the voltage V com2 applied to the common electrode at this time is recorded.

[0184] The difference ΔV com2 between V com and V com2 is calculated, and ΔV com2 is taken as the second voltage adjustment value. The adjustment value of the L0 end voltage corresponding to the dark pixel point of the target cyan picture is ΔV com2 . The L0 end voltage corresponding to the dark pixel point is adjusted in accordance with the above-mentioned adjustment value.

[0185] After adjusting the gray scale voltage (the above-mentioned end voltage), and in accordance with the adjustment direction of the second voltage adjustment value, the residual micro-adjustment is continued to be increased by 0.01-0.02V, and the above-mentioned residual micro-adjustment step is repeated until the flicker defect of the liquid crystal display panel disappears. After the final adjustment is completed, the final adjustment value of the L0 end voltage corresponding to the dark pixel point is -0.05V.

[0186] In an alternative embodiment, Figure 8 A skip1dot cyan picture adjustment flow chart which only adjusts the L127 gray scale voltage is shown as follows, Figure 8 As shown, considering that the picture residual image is easily affected by the change of the L0 end voltage, this embodiment only adjusts the L127 end voltage, and does not change the L0 end voltage, including the following steps:

[0187] For the liquid crystal display panel of the MNT315QHD HADS product, the Single gate (only one row is scanned at a certain moment) + column inversion mode (+-+-…) architecture is used. The L127 gray scale sub-pixel in the non-warmed liquid crystal display panel is lit, and the electric field polarity of the first sub-pixel is adjusted so that the first sub-pixel displays any one of the positive polarity or the negative polarity. The display picture of the liquid crystal display panel in this state is taken as a first picture, and the flicker phenomenon of the first picture is adjusted using a color analyzer CA310. When the first picture is adjusted to a non-flickering state (the flicker value is minimum), the voltage V com =5.826V applied to the common electrode at this time is recorded.

[0188] Subsequently, the special cyan pattern picture is aged for 10 minutes until the special cyan pattern picture does not flicker, and when flicker phenomenon occurs when switching to the L127 gray scale picture, the aging process is stopped, and then the electric field polarity of the sub-pixel in the liquid crystal display panel under the current picture is reversed, so that the first G sub-pixel in the liquid crystal display panel under the current picture displays the L127 gray scale and displays the negative polarity, obtaining a G negative polarity picture.

[0189] The G negative polarity picture is adjusted to a non-flickering state, and the voltage V com1 =5.866V applied to the common electrode at this time is recorded.

[0190] The difference between V com1 and V com is calculated, ΔV com1 =V com1 -V com =5.866-5.826=0.04V, and ΔV com1 is taken as the first voltage adjustment value. Then the adjustment value of the L127 end voltage corresponding to the bright pixel point of the target cyan picture is ΔV com1= 0.04V. The L127 binding point voltage corresponding to the bright pixel point is adjusted according to the above adjustment value.

[0191] After adjusting the gray scale voltage (the above binding point voltage), and according to the adjustment direction of the first voltage adjustment value, the residual micro-adjustment is continued to be increased by 0.01-0.02V, and the above residual micro-adjustment step is repeated until the flicker defect of the liquid crystal display panel disappears.
