[0020] Optionally, each of the regions has the same width extending in the first direction; and / or each of the sub-regions has the same length extending in the second direction, and each of the sub-regions has the same length extending in the first direction.

[0021] As one of the solutions, the step of dividing the image to be displayed into a plurality of areas, and setting the non-display area to a high impedance voltage state or a low grayscale voltage state based on grayscale distribution information of any two adjacent areas in the first direction includes:

[0028] Different from the existing technology, the beneficial effects of this application are:

[0029] The driving method of the display panel provided in the present application pre-collects the picture to be displayed before the display panel displays it, and analyzes the picture to be displayed to obtain its grayscale distribution information in the first direction, and determines whether vertical crosstalk optimization is needed by comparing the absolute value of the difference between the average grayscales of adjacent areas in the first direction with a threshold; if optimization is needed, the non-display area is controlled to be in a low grayscale voltage state, and the non-display area in a dark state will affect the display area adjacent to the light-colored area affected by the dark area of ​​the display area, making it darker, thereby reducing the color difference between the display area and the light-colored area, and effectively optimizing the vertical crosstalk; if vertical crosstalk optimization is not needed, the non-display area is controlled to be in a high-impedance state to reduce energy consumption and unnecessary color influences, and different non-display area voltage states can be dynamically set according to the picture to ensure the effect of each frame of the picture and reduce the effect of vertical crosstalk.

[0030] In addition, the driving method of the display panel provided in the present application adopts a step-by-step refinement analysis method from a large range to a small range to analyze the image to be displayed. For the image to be displayed, it is first determined whether it is a single grayscale image. If it is a single grayscale, no optimization is required. The non-display area is controlled to be in a high-impedance voltage state to avoid the influence of the non-display area on the display effect of the single grayscale image. If it is not a single grayscale image, the image to be displayed is first divided into multiple areas evenly distributed along the first direction, and the absolute value of the difference in the average grayscale of adjacent areas is calculated and compared with the first threshold. If the absolute value of the difference in the average grayscale of any adjacent area is greater than or equal to the first threshold, the non-display area is controlled to be in a low grayscale voltage state to optimize the vertical crosstalk. If the absolute value of the difference in the average grayscale of any adjacent area is greater than or equal to the first threshold, the non-display area is controlled to be in a low grayscale voltage state to optimize the vertical crosstalk. If the absolute values ​​are all smaller than the first threshold, each area is further divided into a plurality of sub-areas arranged along the second direction, and the absolute value of the difference in average grayscale of adjacent sub-areas in the first direction is further calculated and compared with the second threshold. If the absolute value of the difference in average grayscale of any adjacent sub-areas is greater than or equal to the second threshold, the non-display area is controlled to be in a low grayscale voltage state to optimize the vertical crosstalk. If the absolute value of the difference in average grayscale of any adjacent sub-areas is all smaller than the second threshold, there is no need to optimize the vertical crosstalk, and the non-display area is controlled to be in a high impedance state. While ensuring the accuracy of the analysis of the grayscale distribution information of the vertical surface to be displayed, unnecessary data processing is reduced, and the voltage state of the non-display area is dynamically set according to each picture to ensure the optimal display effect of each picture.

[0041] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are protected by this application.

[0042] See also Figure 1 and Figure 2 , Figure 1 1 is a flow chart of an embodiment of a method for driving a display panel of the present application. Figure 2 FIG1 is a schematic diagram of the structure of an embodiment of a display panel. The display panel may be an OLED display panel, an LED display panel, a liquid crystal display panel, etc.

[0043] The display panel 1 includes a display area 101 and a non-display area 102 located in a first direction Y of the display area 101 .

[0044] The first direction Y is a direction perpendicular to the scanning direction of the display panel 1. For a display panel 1 that adopts progressive scanning imaging, the first direction Y is its column direction. Figure 2 As shown, the non-display area 102 can be arranged above and below the display area 101. Of course, in other embodiments, the display panel 1 may also include a non-display area 102 located in a second direction X perpendicular to the first direction Y of the display area 101. However, since the display panel 1 adopts a row scanning method, the non-display area 102 in the driving method mentioned below is only located in the first direction Y of the display area 101. Furthermore, the driving method of the display panel provided in the present application includes:

[0045] S1: Obtaining grayscale distribution information of a picture to be displayed in a display area in a first direction.

[0046] Specifically, if Figure 2As shown, obtaining the grayscale distribution information of the image to be displayed in the first direction refers to obtaining the grayscale information of all pixels in the display area 101, and thereby obtaining the grayscale distribution information of the pixels in the first direction Y. This step can be achieved by adding an image analysis module inside the driver IC, or by an external separate image analysis unit, or by the central processing unit directly analyzing the image to be displayed before sending the information to the driver IC.

[0047] For ease of explanation, this embodiment takes the example of adding an image analysis module inside the driver IC. Inside the driver IC, the voltage configuration module first receives the image information to be displayed sent by the processor, and configures the voltage information of all pixels in the display area 101 according to the image information to be displayed. The voltage information is transmitted to the storage module inside the driver IC for storage. The image analysis module collects the voltage information from the storage module, analyzes it, and thereby obtains the grayscale information of all pixels in the display area 101, and further obtains the grayscale distribution information of the image to be displayed in the first direction Y.

[0048] S2: Setting the voltage state of the non-display area according to the grayscale distribution information.

[0049] The voltage in the non-display area may be a data voltage, that is, the voltage state of the non-display area can be controlled by controlling the data voltage value input to the non-display area via the data line.

[0050] Specifically, see Figure 3 , Figure 3 for Figure 1 Schematic diagram of a flow chart of an embodiment corresponding to step S2 in FIG. The specific implementation process of the above step S2 can be:

[0051] S21 : Firstly, judging whether the image to be displayed is a single grayscale image according to the grayscale distribution information of the image to be displayed in the first direction obtained in S1 .

[0052] Specifically, a single grayscale image refers to an image in which the grayscales of the R, G, and B components of all pixels in the image to be displayed are the same, respectively. The grayscales of the R, G, and B components can be the same or different. The determination method is to compare the grayscale information of all pixels by the image analysis module.

[0053] S22: If the image to be displayed is a single grayscale image, the non-display area is set to a high impedance voltage state.

[0054] S23: If it is not a single grayscale image, dividing the image to be displayed into multiple areas, and setting the non-display area to a high impedance voltage state or a low grayscale voltage state based on grayscale distribution information of any two adjacent areas in the first direction.

[0055] Among them, the high-impedance voltage state mentioned in the above steps S22 and S23 refers to the non-display area 102 being in a disconnected state. At this time, the non-display area is not subjected to any voltage output, which can effectively reduce the energy consumption of the display panel. The low grayscale voltage state refers to the voltage state that controls the non-display area 102 to display a dark image. In one embodiment, the low grayscale voltage state can be a 0 grayscale voltage state, that is, controlling the non-display area 102 to display a black image. In other embodiments, the low grayscale voltage state can also include other voltage states that control the non-display area to display a dark image, all of which can achieve the effect of this embodiment. In order to improve the optimization effect of vertical crosstalk, the low grayscale voltage state is preferably a 0 grayscale voltage state.

[0056] Among them, setting the non-display area state is achieved through the non-display area setting module inside the driver IC, namely the Blank setting module. In one embodiment, the image analysis module controls the Blank setting module to set the voltage state of the non-display area according to the analysis results. In other embodiments, the image analysis module feeds back the analyzed image to be displayed and the signal obtained according to the analysis results to the Blank setting module, and the Blank setting module sets the voltage state of the non-display area, thereby obtaining all the display information of the display panel.

[0057] Specifically, in one embodiment, see Figure 4 , Figure 4 for Figure 3 Flowchart of an embodiment corresponding to step S23 in the above step S23, wherein the image to be displayed is divided into a plurality of regions, and the non-display region is set to a high impedance voltage state or a low grayscale voltage state based on the grayscale distribution information of any two adjacent regions in the first direction, comprises:

[0058] S231: Divide the image to be displayed into a plurality of regions arranged along a first direction, wherein a length of each region extending along a second direction perpendicular to the first direction is the same as a length of the image to be displayed extending along the second direction.

[0059] Specifically, Figure 5 Schematic diagram of a structure of an embodiment of dividing a picture to be displayed into multiple areas. Figure 5 As shown, the image to be displayed is divided into n areas arranged along a first direction Y, and each area extends from one end to the other end of the display area.

[0060] In one embodiment, each region has the same width in the first direction Y, that is, the image to be displayed is evenly divided into multiple regions in the first direction Y, thereby ensuring the accuracy of the analysis of the uniformity of the grayscale distribution on the vertical plane. Of course, in other embodiments, the widths of two adjacent regions in the first direction Y may also be different.

[0061] In order to improve the accuracy of the analysis, the picture to be displayed may be divided into as many areas as possible arranged along the first direction Y within a certain limit without increasing the amount of data processing.

[0062] S232: In response to the absolute value of the difference between the average grayscales of any two adjacent regions in the first direction being greater than or equal to the first threshold, setting the non-display area to a low grayscale voltage state.

[0063] Specifically, Figure 5 For example, Figure 5 The image to be displayed is divided into n areas arranged along the first direction Y. At this time, the average grayscale of each area can be obtained first; then any two adjacent areas among the n areas are combined to form n-1 combinations; for each combination, the absolute value of the difference between the average grayscales of the two adjacent areas in the combination is obtained.

[0064] When the absolute value of the difference corresponding to at least one combination is greater than or equal to the first threshold, it indicates that there is a grayscale mutation between two adjacent areas in the combination, and vertical crosstalk is more likely to occur; therefore, the non-display area 102 can be set to a low grayscale voltage state at this time.

[0065] Vertical crosstalk is caused by the large grayscale difference between adjacent areas on the vertical plane, such as Figure 2 Display blocks a and b in the middle display area are grayscale black. Since the grayscale of display block c is significantly different from that of display blocks a and b, the display color of display block c will be affected and darkened, resulting in a significant color difference between display block c and display blocks d and e, affecting the viewing experience.

[0066] After the non-display area 102 is set to a low grayscale voltage state, since the non-display area 102 is displayed in a dark color, the display blocks d and e will be affected by the non-display area 102 and become darker, thereby reducing the color difference between the display blocks d, e and c, and optimizing the vertical crosstalk problem.

[0067] Among them, the first threshold can be adjusted and selected according to product and customer needs. For example, in usage scenarios with high requirements for display color uniformity, the first threshold can be set to a smaller value, while in usage scenarios with low requirements for display color uniformity, the first threshold can be set to a larger value.

[0068] In one application scenario, synchronously with the above step S232 , in response to the absolute value of the difference between the average grayscales of any two adjacent regions in the first direction being less than a first threshold, the non-display area is set to a high impedance voltage state.

[0069] When the absolute values ​​of the differences corresponding to all combinations are less than the first threshold, it indicates that there is no grayscale mutation in the first direction Y in the image to be displayed, and the probability of vertical crosstalk is low. Therefore, the non-display area 102 is set to a high-impedance voltage state at this time to reduce energy consumption and unnecessary color impact.

[0070] In one application scenario, synchronously with the above step S232, in response to the absolute value of the difference between the average grayscales of any two adjacent regions in the first direction being less than a first threshold, each region is divided into a plurality of sub-regions arranged along the second direction;

[0071] In response to the absolute value of the difference between the average grayscales of any two sub-areas adjacent in the first direction being greater than or equal to a second threshold, the non-display area is set to a low grayscale voltage state; and in response to the absolute value of the difference between the average grayscales of any two sub-areas adjacent in the first direction being less than the second threshold, the non-display area is set to a high impedance voltage state.

[0072] Since the area in the first direction Y includes all pixels from one end to the other end of the display area in the second direction X, its average grayscale is actually the average grayscale of all pixels within a certain width in the second direction X. Figure 5 The average grayscale of the areas corresponding to display blocks a and display blocks b also includes part of the content of display blocks d and display blocks e. Therefore, when performing comparison, the absolute value of the difference in the average grayscale of the areas corresponding to display blocks a and display blocks b and the area corresponding to display block c cannot accurately reflect the actual grayscale distribution difference on the vertical surface.

[0073] In order to further improve the accuracy of the analysis of the grayscale distribution uniformity on the vertical surface, each area in the first direction Y can be further divided. In a usage scenario, Figure 6 This is a structural diagram of another embodiment of dividing the image to be displayed into multiple areas. Figure 6 , each region is divided into m sub-regions arranged along the second direction X, thereby forming a two-dimensional network consisting of nm sub-regions.

[0074] Calculate the average grayscale of each sub-region, and calculate the absolute value of the difference between the average grayscales of two adjacent sub-regions in the first direction Y, referring to Figure 6 , that is, comparing the absolute value of the difference in average grayscale between sub-region 11 and sub-region 12, between sub-region 12 and sub-region 13, ..., between sub-region 21 and sub-region 22, .... At this time, referring to Figure 6 The sub-areas corresponding to display blocks a, display blocks b, and display blocks c only include themselves, and their average grayscale represents the actual grayscale distribution. The absolute value of the difference between the average grayscales of adjacent sub-areas can also more accurately reflect the uniformity of grayscale distribution on the vertical surface.

[0075] Among them, the second threshold refers to the first threshold and can be adjusted and selected according to product and customer needs, which will not be repeated here.

[0076] When the absolute value of the difference in average grayscale between any two adjacent sub-areas in at least one group in the first direction Y is greater than or equal to the second threshold, it is determined that vertical crosstalk optimization is required. At this time, the non-display area is controlled to be in a low grayscale voltage state, that is, the non-display area 102 is displayed in a dark color. At this time, the display block d and the display block e will be affected by the non-display area 102 and become darker, thereby reducing the color difference between the display block d, the display block e and the display block c, and optimizing the vertical crosstalk problem.

[0077] When the absolute value of the difference in average grayscale between any two adjacent sub-areas in the first direction Y is less than the second threshold, it is determined that no vertical crosstalk optimization is required. At this time, the non-display area is controlled to be in a high impedance state to reduce energy consumption and unnecessary color impact.

[0078] Preferably, each sub-region has the same length extending in the second direction X and the same width extending in the first direction Y, that is, the image to be displayed is evenly divided into multiple sub-regions in the first direction Y and the second direction X, thereby ensuring the accuracy of the analysis of the uniformity of the grayscale distribution on the vertical plane. Of course, in order to improve the accuracy of the analysis, each region can also be divided into as many sub-regions as possible arranged along the second direction X within a certain limit while avoiding excessive data processing.

[0079] Of course, in other embodiments, the image to be displayed may be directly subdivided into multiple regions when executing step S23. The specific process may be: when the image to be displayed is not a single grayscale image, the image to be displayed may be directly divided into multiple regions in the first direction Y and the second direction X, the absolute value of the difference in average grayscale between adjacent regions in the first direction Y is calculated, the grayscale distribution uniformity on the vertical plane is analyzed, and the absolute value of the difference is then compared with a threshold to determine whether vertical crosstalk optimization is required. However, since this solution does not have a gradual analysis process from a large range to a small range, it may increase the amount of data analysis. For example, when the image to be displayed is divided into multiple regions arranged along the first direction Y, if the absolute value of the difference in average grayscale between adjacent regions is greater than the first threshold, the non-display area 102 can be directly set to a low grayscale voltage state without further dividing the region into sub-regions arranged along the second direction X.

[0080] In one embodiment, in order to further reduce energy consumption and data processing volume, the following steps are further included before step S21:

[0081] The voltage state of the non-display area is set to a high impedance voltage state.

[0082] Specifically, the voltage state of the non-display area 102 can be preset to a high-impedance voltage state through the Blank setting module. At this time, the non-display area 102 is in a disconnected state with no voltage input, which can effectively reduce energy consumption. The image analysis module then determines whether the voltage state of the non-display area 102 needs to be adjusted to a low grayscale voltage state based on the analysis results. If adjustment is not required, the Blank setting module does not need to reset the voltage state of the non-display area 102. The image analysis module can directly integrate the preset voltage information of the non-display area 102 with the processing information of the image to be displayed to obtain the image information to be displayed on the display panel 100. If adjustment is required, the Blank setting module resets the voltage state of the non-display area 102 and integrates it with the processing information of the image to be displayed to obtain the image information to be displayed on the display panel 100.

[0083] S3: Synchronously drive the display area and the non-display area to operate, wherein the display area displays the image to be displayed, and the non-display area operates based on the set voltage state of the non-display area.

[0084] After the voltage state of the non-display area 102 is set, the voltage information of the non-display area 102 and the information of the image to be displayed are sent to the display panel for display.

[0085] In one embodiment, the Blank setting module does not preset the voltage state of the non-display area 102. After receiving the information from the image analysis module, the Blank setting module inside the driver IC sets the voltage state of the non-display area 102. After the setting is completed, the voltage information of the non-display area 102 and the information of the image to be displayed are directly sent to the image correction module inside the driver IC, such as the gamma correction module and the demura correction module, which are processed by the image correction module and then sent to the display panel for display.

[0086] In another embodiment, the Blank setting module presets the voltage state of the non-display area 102 to a high-impedance voltage state. If the image analysis module analyzes that the voltage state of the non-display area 102 does not need to be changed, the image analysis module sends the preset voltage information of the non-display area 102 and the processing information of the picture to be displayed to the image correction module, which is processed by the image correction module and then sent to the display panel for display; if the image analysis module analyzes that the voltage state of the non-display area 102 needs to be changed, the Blank setting module sets the voltage state of the non-display area 102 after receiving the information from the image analysis module. After the setting is completed, the voltage information of the non-display area 102 and the information of the picture to be displayed are directly sent to the image correction module inside the driver IC, which is processed by the image correction module and then sent to the display panel for display.

[0087] Reference Figure 7 , Figure 7The structure diagram of an embodiment of the working state of the display panel. After the non-display area 102 is set to a low grayscale voltage state, the non-display area 102 is preset to a high impedance voltage state. Figure 2 In the display diagram of the display panel, the colors of display blocks d and e are darkened due to the influence of the non-display area 102, thereby reducing the color difference between display blocks d, e and c, effectively optimizing the vertical crosstalk problem.
