[0079] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0080] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0081] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0082] In order to better understand the detection and adjustment method of a display screen module provided by an embodiment of the present application, the following is a brief introduction to the method for adjusting the first line of the LED display screen that is dark in the existing scheme. In the existing scheme, since the first line of the LED display screen is dark because for an LED scanning block, in the process of displaying an image, the driver chip of the LED scanning block usually scans in units of lines, and in the scanning process, after lighting a row of lamp beads and before lighting the next row of lamp beads, the parasitic capacitor will be charged. Therefore, due to the charging and discharging of the parasitic capacitor, when switching the screen, there will be differences in the charging and discharging time of the parasitic capacitor. For example, after one image is displayed, when the next image needs to be displayed, the LED scanning block starts from the last image. The row needs to be switched to the first row to scan again and light up the lamp beads in each row in turn, so that the parasitic capacitor corresponding to the lamp beads in the first row needs to experience a higher charging and discharging time than the charging and discharging time of subsequent rows when the screen is switched, resulting in a larger current when the parasitic capacitor releases current, and the current released by the parasitic capacitor will weaken the current when the lamp beads are lit. Therefore, the degree of current weakening when lighting the first row of lamp beads is greater than the degree of current weakening when lighting the non-first row of lamp beads, resulting in the first row of the LED scanning block being darker without adjusting the display brightness. In order to solve the above problems, in the existing scheme, the brightness adjustment parameters are determined by obtaining the difference between the brightness mean of the first row of lamp beads and the brightness mean of the non-first row of lamp beads, or the brightness adjustment parameters are determined by the median value, etc. However, by determining the brightness adjustment parameters by the brightness mean or median of the first row of lamp beads and the non-first row of lamp beads, the brightness adjustment parameters can only be determined by irregular group commonalities. When adjusting each different lamp bead, there are visual differences on different scanning blocks when the user watches the image displayed by the LED scanning block, so that the actual adjustment effect after adjusting the adjustment parameters determined by the aforementioned method may not be able to meet the user's viewing needs well, thereby reducing the accuracy when adjusting the brightness.

[0083] Aiming to solve the problem of low accuracy in brightness adjustment in the prior art solutions, an embodiment of the present application provides a detection and adjustment method for a display screen module, which can determine the target brightness adjustment parameters based on the second display brightness information of the associated scanning block and the display brightness information of the target LED scanning block when it is detected that the display brightness of the first row of lamp beads in the target LED scanning block in the LED display screen to be detected is abnormal. Since the display brightness of the associated LED scanning module will affect the display brightness of the target LED scanning block, the brightness adjustment parameters can be determined in combination with the display brightness of the associated LED scanning block, thereby improving the accuracy of determining the brightness adjustment parameters and further improving the accuracy of display brightness adjustment.

[0084] See also Figure 1 , Figure 1 A schematic diagram of the structure of an LED display screen is provided for an embodiment of the present application. Figure 1 As shown, the LED display screen includes a first LED scanning block and a second LED scanning module, and the specifications of the first LED scanning block and the second LED scanning module are the same. The first LED scanning block has multiple rows of lamp beads, and the display brightness of the first row of lamp beads is lower than the display brightness of the subsequent rows of lamp beads. In the splicing part of the first LED scanning block and the second LED scanning block, the display brightness of the last row of lamp beads of the first LED scanning block will affect the display brightness of the first row of lamp beads of the second LED scanning block, so if the target LED scanning block is the second LED scanning block at this time, then its corresponding associated LED scanning block is the first LED scanning block. Therefore, the display brightness of the last row of lamp beads of the first LED scanning block can be used to adjust the display brightness of the first row of lamp beads of the second LED scanning block, etc. At the same time, the display brightness of the second row of lamp beads of the second LED scanning block will also affect the display brightness of the first row of lamp beads, so that the display brightness of the last row of lamp beads of the first LED scanning block and the display brightness of the second row of lamp beads of the second LED scanning block can be combined to jointly determine the brightness adjustment parameters of the first row of lamp beads of the second LED scanning block, thereby improving the accuracy of determining the brightness adjustment parameters, and then improving the accuracy of brightness adjustment.

[0085] See also Figure 2A , Figure 2A The present invention provides a flow chart of a detection and adjustment method of a display screen module. Figure 2A As shown, the method is applied to an LED display screen, and the method includes:

[0086] 201. Perform display brightness detection on a target LED scanning block in the LED display screen to be detected, and obtain a display brightness detection result.

[0087] The LED display screen to be detected can be any LED display screen that needs to be tested for brightness, for example, it can be a display screen composed of multiple LED scanning blocks, each of which has its own independent control unit, or can be uniformly controlled by one control unit.

[0088] When detecting the display brightness of the target LED scanning block, a general display brightness detection method may be used, for example, detection is performed through a brightness detection sensor, or for another example, a display image of the LED scanning block is collected through a camera, and analyzed and processed to obtain the display brightness. After obtaining the display brightness, it can be judged, for example, whether the difference between the display brightness of the first row of lamp beads and the display brightness of the remaining rows of lamp beads is too large. If it is too large, the first display brightness of the first row of lamp beads can be determined as abnormal display brightness. If the difference is small, the first display brightness of the first row of lamp beads can be determined as normal display brightness. Whether the difference is too large can be understood as whether the difference is greater than a preset difference threshold. If it is greater than or equal to the preset difference threshold, the difference is too large. If it is less than the preset difference threshold, the difference is small.

[0089] 202. If the display brightness detection result is that the first display brightness of the first row of lamp beads of the target LED scanning block is abnormal display brightness, obtain second display brightness information of the LED scanning block associated with the target LED scanning block.

[0090] The associated LED scanning block of the target LED scanning block may be an LED scanning block adjacent to the first row (first row) of the target LED scanning block. Figure 2B As shown, Figure 2B A schematic diagram of an associated LED scanning block and a target LED scanning block is shown in FIG.

[0091] The second display brightness information of the associated LED scanning block includes the display brightness information of each row of lamp beads of the associated LED scanning block. Figure 2B As shown, it may include a target row of lamp beads adjacent to the first row of lamp beads of the target LED scanning block, as well as other lamp beads, etc.

[0092] The method for obtaining the second display brightness information can be obtained by using a common lamp bead display brightness acquisition method, which will not be described in detail here.

[0093] 203. Determine a first brightness adjustment parameter according to the second display brightness information and the first display brightness information.

[0094] Among them, the second sub-display brightness information of the target row of lamp beads adjacent to the first row of lamp beads of the target LED scanning block can be extracted from the second display brightness information. Then, the first row of lamp beads and the target row of lamp beads can be grouped to obtain k lamp bead groups, and the display brightness information corresponding to each lamp bead group can be extracted, thereby obtaining k display brightness information vectors, and finally the first brightness adjustment parameter is determined according to the k display brightness information vectors. K can be the number of lamp beads in the first row of lamp beads or the target row of lamp beads.

[0095] 204. Obtain third display brightness information of the target LED scanning block, where the third display brightness information is display brightness information of the target LED scanning block except for the first display brightness of the first row of lamp beads.

[0096] The third display brightness information may be obtained by adopting a general method for obtaining the display brightness of lamp beads, and specifically, the display brightness information of the second row of lamp beads to the display brightness information of the last row of lamp beads in the target LED scanning block.

[0097] 205. Determine a second brightness adjustment parameter according to the third display brightness information and the first display brightness information.

[0098] Among them, the fourth display brightness information of the second row of lamp beads adjacent to the first row of lamp beads can be extracted from the third display brightness information, and the brightness influence parameter can be determined based on the relative position of each lamp bead in the second row to each lamp bead in the first row, and the second brightness adjustment parameter can be determined based on the brightness influence parameter, the first display brightness and the third display brightness information, so that the second brightness adjustment parameter can be determined in combination with the brightness influence factor of the second row of lamp beads on each lamp bead in the first row, thereby improving the accuracy of determining the second brightness adjustment parameter.

[0099] 206. Determine a target brightness adjustment parameter according to the first brightness adjustment parameter and the second brightness adjustment parameter.

[0100] The first brightness adjustment parameter and the second brightness adjustment parameter may be weighted to obtain a target brightness adjustment parameter. Specifically, a first weight corresponding to the first brightness adjustment parameter and a second weight corresponding to the second brightness adjustment parameter may be obtained respectively, and a weighted operation may be performed on the first brightness adjustment parameter and the second brightness adjustment parameter according to the first weight and the second weight to obtain the target brightness adjustment parameter. The target brightness adjustment parameter may be used to adjust the brightness of the first row of lamp beads to improve the display brightness of the first row of lamp beads.

[0101] 207. Adjust the display brightness of the first row of lamp beads of the target LED scanning block according to the target brightness adjustment parameter.

[0102] The target brightness adjustment parameters can be used to adjust the display brightness of the first row of lamp beads in the target LED scanning block to increase the display brightness of the first row of lamp beads, thereby reducing the situation where the first row of the LED scanning block is dark and improving the display effect.

[0103] In this example, when it is detected that the display brightness of the first row of lamp beads in the target LED scanning block in the LED display screen to be detected is abnormal, the target brightness adjustment parameters can be determined according to the second display brightness information of the associated scanning block and the display brightness information of the target LED scanning block. Since the display brightness of the associated LED scanning module will affect the display brightness of the target LED scanning block, the brightness adjustment parameters can be determined in combination with the display brightness of the associated LED scanning block, thereby improving the accuracy of determining the brightness adjustment parameters and further improving the accuracy of display brightness adjustment.

[0104] In one possible implementation, when determining the brightness parameters of the lamp beads in the existing solution, the display brightness of the first row of lamp beads is usually adjusted to the average display brightness of the region based on the display brightness of the first row of lamp beads themselves, combined with the average display brightness of the target LED scanning block, etc., to reduce the situation where the first row is too dark. However, when the average brightness is used for adjustment, there are usually some extreme changes in the actual display situation, such as occasional display instability, so that the accuracy of the adjustment using the average brightness as the adjustment standard will be reduced. In order to solve the above problem, an embodiment of the present application provides a method for determining the first brightness adjustment parameter based on the second display brightness information and the first display brightness information, so as to use the display brightness of the target row of lamp beads adjacent to the first row of lamp beads in the target LED scanning block in the associated LED scanning module, and then determine the brightness adjustment parameter in combination with the display brightness of each lamp bead, so that the display situation of each lamp bead can be concretely adjusted, thereby improving the accuracy of determining the first brightness adjustment parameter. The method is as follows:

[0105] A1, extracting the second sub-display brightness information of the target row of lamp beads adjacent to the first row of lamp beads of the target LED scanning block from the second display brightness information;

[0106] A2. Group the lamp beads in the first row and the target row to obtain k lamp bead groups, each lamp bead group including a first lamp bead and a second lamp bead. The first lamp bead is a lamp bead in the first row, the second lamp bead is a lamp bead in the target row, and the first lamp bead and the second lamp bead are located in the same column.

[0107] A3, extracting display brightness information corresponding to k lamp bead groups from the second sub-display brightness information and the first display brightness information to obtain k display brightness information vectors;

[0108] A4, calculating brightness adjustment parameters according to the k display brightness information vectors respectively, to obtain k first sub-brightness adjustment parameters;

[0109] A5. Determine the first brightness adjustment parameter according to k first sub-brightness adjustment parameters.

[0110] The second display brightness information includes the second sub-display brightness information of the target row of lamp beads. Specifically, the second sub-display brightness information can be extracted from the second display brightness information according to the identification information corresponding to the second sub-display brightness information. The second sub-display brightness information includes the display brightness information of each lamp bead in the target row of lamp beads, and the display brightness information may include the display brightness of the lamp bead, and the display brightness can be characterized by the display brightness value.

[0111] like Figure 2C As shown, Figure 2C A schematic diagram of grouping the first row of lamp beads and the target row of lamp beads to obtain k lamp bead groups is shown in FIG. The display brightness information of the lamp beads in the target row of lamp beads in the lamp bead group can be extracted from the second sub-brightness information, and the display brightness information of the lamp beads in the first row of lamp beads in the lamp bead group can be extracted from the first display brightness information, and represented in the form of vectors, thereby obtaining k display brightness information vectors.

[0112] The k lamp bead groups can be divided into the first lamp bead group and k-1 second lamp bead groups. The first lamp bead group is the lamp bead group located in the middle of the target LED scanning block among the k lamp bead groups. Being located in the middle of the target LED scanning block can be understood as the first lamp bead in the first lamp bead group being located in the middle of the first row of lamp beads. Specifically, it can be understood that if there are 11 lamp beads in the first row of lamp beads, the first lamp bead in the first lamp bead group is the sixth lamp bead from left to right in the first row of lamp beads. Obtain the brightness influence factors of the k-1 second lamp bead groups on the first lamp bead group respectively, and then determine the first reference brightness adjustment parameter according to the brightness influence factor and the corresponding display brightness information vector, and determine the second reference brightness adjustment parameter corresponding to the first lamp bead according to the display brightness of the second lamp bead in the first lamp bead group. Finally, determine the third reference brightness adjustment parameter according to the first reference brightness adjustment parameter and the second reference brightness adjustment parameter, and determine the third reference brightness adjustment parameter as the first brightness adjustment parameter.

[0113] Finally, since the k first sub-brightness adjustment parameters are the same, any one of the k first sub-brightness adjustment parameters can be determined as the first brightness adjustment parameter, thereby improving the efficiency of obtaining the first brightness adjustment parameter.

[0114] At the same time, a third reference brightness adjustment parameter can be determined based on the brightness influencing factor between each lamp bead group and the brightness influence of the second lamp bead on the first lamp bead, and the third reference brightness adjustment parameter can be determined as the first sub-brightness adjustment parameter, thereby obtaining k first sub-brightness adjustment parameters, thereby improving the accuracy of determining the first sub-brightness adjustment parameter.

[0115] In a possible implementation, a method for calculating brightness adjustment parameters according to k display brightness information vectors to obtain k first sub-brightness adjustment parameters includes:

Divide the k lamp bead groups into a first lamp bead group and k-1 second lamp bead groups, wherein the first lamp bead group is a lamp bead group located in the middle of the target LED scanning block among the k lamp bead groups, and the second lamp bead group is a lamp bead group among the k lamp bead groups except the first lamp bead group;

[0117] B2, obtaining the brightness influence factors of the k-1 second lamp bead groups on the first lamp bead group to obtain k-1 target brightness influence factors;

[0118] B3. Determine a first reference brightness adjustment parameter of the first lamp bead group according to k-1 target brightness influencing factors and the display brightness information vector corresponding to the second lamp bead group;

[0119] B4, determining a second reference brightness adjustment parameter of the display brightness information corresponding to the first lamp bead according to the display brightness information corresponding to the second lamp bead in the display brightness information vector of the first lamp bead group;

[0120] B5. Determine a third reference brightness adjustment parameter corresponding to the first lamp bead group according to the first reference brightness adjustment parameter and the second reference brightness adjustment parameter;

[0121] B6. Determine the third reference brightness adjustment parameter as the first sub-brightness adjustment parameter to obtain k first sub-brightness adjustment parameters.

[0122] Among them, the first lamp bead group is the lamp bead group located in the middle of the target LED scanning block among the k lamp bead groups. Specifically, it can be understood that being located in the middle of the target LED scanning block can be understood as the first lamp bead in the first lamp bead group being located in the middle position of the first row of lamp beads. Specifically, it can be understood that if there are 11 lamp beads in the first row, the first lamp bead in the first lamp bead group is the sixth lamp bead from left to right in the first row of lamp beads.

[0123] The brightness influence factor of the second lamp bead group on the first lamp bead group can be determined according to the position information of the second lamp bead group and the position information of the first lamp bead group. Specifically, the distance between the second lamp bead group and the first lamp bead group can be determined according to the position information of the second lamp bead group and the position information of the first lamp bead group, and the brightness influence factor is determined according to the distance. Specifically, the larger the distance, the smaller the brightness influence factor, and the smaller the distance, the larger the brightness influence factor. Therefore, the target brightness influence factor can be determined according to the distance.

[0124] The display brightness information of the second lamp bead group includes the display brightness information of the first lamp bead and the display brightness information of the second lamp bead. At this time, the display brightness information of the second lamp bead in the second lamp bead group can be extracted, and the brightness adjustment parameter of the corresponding second lamp bead group relative to the first lamp bead group can be determined according to the display brightness information of the second lamp bead and the target brightness influence factor. Finally, the brightness adjustment parameter of each second lamp bead group relative to the first lamp bead group is fused to obtain the first reference brightness adjustment parameter. Among them, according to the display brightness information of the second lamp bead and the target brightness influence factor, the method for determining the brightness adjustment parameter of the corresponding second lamp bead group relative to the first lamp bead group can be: the display brightness in the display brightness information of the second lamp bead can be multiplied by the target brightness influence factor to obtain the brightness adjustment parameter of the second lamp bead group relative to the first lamp bead group. The method for fusion processing of the brightness adjustment parameter of each second lamp bead group relative to the first lamp bead group to obtain the first reference brightness adjustment parameter can be summing the brightness adjustment parameter of each second lamp bead group relative to the first lamp bead group to obtain the final adjustment parameter value, and the final adjustment parameter value is determined as the first reference brightness adjustment parameter.

[0125] The display brightness information corresponding to the second lamp bead can be extracted from the display brightness information vector of the first lamp bead group, and the display brightness information of the first lamp bead can be extracted. Since the display brightness of the second lamp bead in the first lamp bead group has the greatest influence on the first lamp bead, the display influence of the second lamp bead in the first lamp bead group on the first lamp bead in the first lamp bead group can be determined as a preset influence, and the preset influence is set by empirical values ​​or historical data. Therefore, the second reference brightness adjustment parameter can be determined based on the influence and the display brightness difference between the second lamp bead and the first lamp bead in the first lamp bead group. Specifically, the product of the influence and the display brightness difference between the second lamp bead and the first lamp bead in the first lamp bead group can be determined as the second reference brightness adjustment parameter.

[0126] The sum of the second reference brightness adjustment parameter and the first reference brightness adjustment parameter can be determined as the third reference brightness adjustment parameter. When the third reference brightness adjustment parameter is used to adjust the brightness, it can act on each lamp bead in the first row of lamp beads, and make each lamp bead adjust with the same force, so that the adjustment tends to be stable, thereby improving the display effect. Specifically, when the brightness adjustment effect of the third reference brightness adjustment parameter is used on the lamp beads, each lamp bead is adjusted in the same way to improve stability.

[0127] In a possible implementation, a method for determining a second reference brightness adjustment parameter of display brightness information corresponding to a first lamp bead according to display brightness information corresponding to a second lamp bead in a display brightness information vector of a first lamp bead group includes:

[0128] C1. determining a first display brightness difference according to display brightness information corresponding to the second lamp bead and display brightness information corresponding to the first lamp bead in the first lamp bead group;

[0129] C2. Determine the brightness difference level between the first lamp bead and the second lamp bead according to the first display brightness difference value;

[0130] C3. Determine a brightness adjustment coefficient according to the brightness difference level;

[0131] C4. Determine the second reference brightness adjustment parameter according to the display brightness information corresponding to the second lamp bead and the brightness adjustment coefficient.

[0132] Among them, the difference between the display brightness value extracted from the display brightness information corresponding to the second lamp bead and the display brightness value extracted from the display brightness information corresponding to the first lamp bead can be determined as the first display brightness difference value.

[0133] Different display brightness difference intervals correspond to different brightness difference levels. For example, the display brightness difference interval is 0.00-0.02, corresponding to the first brightness difference level, the display brightness difference interval is 0.02-0.03, corresponding to the second brightness difference level, the display brightness difference interval is 0.03-0.04, corresponding to the third brightness difference level, and the display brightness difference interval is above 0.04, corresponding to the fourth brightness difference level. Different brightness difference levels correspond to different brightness adjustment coefficients. The higher the brightness difference level, the larger the brightness adjustment coefficient, and the lower the brightness difference level, the smaller the brightness adjustment coefficient. The product of the display brightness value and the brightness adjustment coefficient in the display brightness information corresponding to the second lamp bead can be determined as the second reference brightness adjustment parameter. Therefore, the second reference brightness adjustment parameter can be quickly determined, which improves the efficiency of subsequent brightness adjustment and improves the display effect.

[0134] In a possible implementation, a method for determining a second brightness adjustment parameter according to the third display brightness information and the first display brightness information includes:

[0135] D1, extracting fourth display brightness information of the second row of lamp beads adjacent to the first row of lamp beads from the third display brightness information;

[0136] D2. Determine the brightness influencing parameter of each lamp bead in the second row relative to each lamp bead in the first row according to the relative position information of each lamp bead in the second row relative to each lamp bead in the first row, and obtain a first brightness influencing parameter set;

[0137] D3, determining a sub-brightness adjustment parameter corresponding to each lamp bead in the first row of lamp beads according to the first display brightness information, the third display brightness information and the first brightness influencing parameter set;

[0138] D4. Determine the second brightness adjustment parameter according to the sub-brightness adjustment parameter corresponding to each lamp bead in the first row of lamp beads.

[0139] Among them, the second row of lamp beads can be understood as the lamp beads adjacent to the first row of lamp beads in the target LED scanning block, and the number of the lamp beads is the same as the number of the lamp beads in the first row, and the arrangement specifications are the same. Since the second row of lamp beads and the first row of lamp beads are both lamp beads in the target LED scanning block, the influence between them will be higher than the associated LED scanning block. Therefore, the position information corresponding to the second row of lamp beads and each first row of lamp beads is used to respectively determine the brightness influence between them, and obtain the first brightness influence parameter set.

[0140] The brightness influencing parameters corresponding to the target lamp bead in the first row of lamp beads and the corresponding lamp bead in the second row can be obtained respectively, and the target lamp bead is any one of the lamp beads in the first row. Specifically, it can be: the lamp bead corresponding to the target lamp bead is the lamp bead in the second row of lamp beads that is in the same column as the target lamp bead. Since the parameters of each lamp bead are different when leaving the factory, the subtle influence degrees between the lamp beads will also be different, so that the first brightness influencing parameter can be determined according to the attribute parameters of the target lamp bead and the corresponding lamp bead in the second row. Specifically, the first brightness influencing parameter can be determined by the difference information between the attribute parameters. The larger the difference information, the larger the first brightness influencing parameter, and the smaller the difference information, the smaller the first brightness influencing parameter. The above method for obtaining the brightness influencing parameters of the target lamp bead can be repeatedly executed to obtain the brightness influencing parameters of each lamp bead in the first row of lamp beads to obtain the first brightness influencing parameter set.

[0141] The sub-brightness adjustment parameter corresponding to each target lamp bead can be determined according to the first display brightness information, the third display brightness information and the first brightness influence parameter corresponding to the first brightness influence parameter set. Specifically, the sub-brightness adjustment parameter can be determined according to the first brightness influence parameter and the display brightness difference of the corresponding lamp bead in the corresponding third display brightness information and the first display brightness information. For example, the product of the display brightness difference and the first brightness influence parameter can be determined as the sub-brightness adjustment parameter.

[0142] The sub-brightness adjustment parameters corresponding to each lamp bead in the first row of lamp beads can be determined as the second brightness adjustment parameters. Specifically, when making adjustments, each lamp bead in the first row of lamp beads can be adjusted. When determining the target adjustment parameter by combining the first brightness adjustment parameter and the second brightness adjustment parameter, the first brightness adjustment parameter can be superimposed on each second brightness adjustment parameter to obtain the adjusted second brightness adjustment parameter, and the adjusted second brightness adjustment parameter is determined as the target brightness adjustment parameter.

[0143] In this example, the brightness adjustment influencing parameter can be determined by combining the difference information between the attribute parameters of each lamp bead, and finally the second brightness adjustment parameter is determined, thereby improving the accuracy of determining the second brightness adjustment parameter.
