[0036] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention provides an intelligent power-on method, system, device and storage medium of an LED display screen, which are used to solve the color difference display problem when different models of LED display screens are spliced ​​in the prior art.

[0038] See also Figure 1 , Figure 1 The present invention provides a first flow chart of an intelligent power-on method for an LED display screen according to an embodiment of the present invention.

[0039] S100, obtaining the splicing structure of the current LED display screen and the location of the display screen to be replaced, and identifying the adjacent display screens adjacent to the display screen to be replaced;

[0040] It should be noted that when multiple LED screens are spliced ​​into a large screen to display content, the splicing structure is the display screens spliced ​​into m*n, that is, several rows and columns. The determinant expression can be used. For example, 6 screens form a spliced ​​large screen with 2 rows and 3 columns. The screen located in the 1st row and 2nd column can be expressed as A. 12 , and can store the parameters and configuration data of each display screen in the form of a determinant, and each item of the determinant corresponds to the data address of the display screen at the location;

[0041] The host is connected to the HDMI matrix with a high-definition cable, and then the image is input to multiple spliced ​​display screens through the HDMI matrix for splicing display. During use, each display screen and the matrix maintain signal connection. The matrix can detect whether the high-definition cable between the output interface and the display screen is connected. When a certain display screen is disconnected, it can be regarded as the line of the display screen at that position is manually disconnected. At this time, the display screen at that position needs to be replaced, and the item corresponding to the position is recorded. The position of the display screen to be replaced is determined by the number of the determinant;

[0042] The position of the display screen to be replaced is translated, that is, the number of rows of the item's subscript is increased by 1 and subtracted by 1, or the number of columns of the item's subscript is increased by 1 and subtracted by 1, respectively. If there is a corresponding display screen position item, the corresponding item is identified as an adjacent display screen. If the subscript is 0 or greater than the maximum number of rows or columns after translation, there is no adjacent display screen in the adjacent direction, and the number of rows and columns of each display screen adjacent to the current position of the display screen to be replaced in the determinant is obtained. In this embodiment, only adjacent display screens in the same row and in the same column are considered. Only one corner of the obliquely adjacent display screen is adjacent, and the color difference contrast is not visually obvious, so it is not considered in this embodiment;

[0043] S200, obtaining parameters of adjacent display screens, determining whether the number of adjacent display screens in the same row or column is greater than one, if not, obtaining configuration data of the adjacent display screens and power-on display screen parameters, substituting them into a power-on configuration model, and obtaining power-on configuration data, wherein the power-on configuration model is specifically:

[0044]

[0045] Among them, L ab is the peak brightness of the display screen when powered on, l ab is the brightness ratio of the power-on display screen, L1 is the peak brightness of the first adjacent display screen, l1 is the brightness ratio of the first adjacent display screen, C ab is the saturation of the power-on display, C1 is the saturation of the first adjacent display, S ab is the color gamut coverage ratio of the powered-on display screen, S1 is the color gamut coverage ratio of the first adjacent display screen, δ is the display data and color correction coefficient, α is the minimum color difference value that the human eye can recognize, β is the minimum value of the brightness difference that the human eye can recognize, is the color reference value;

[0046] It should be noted that the quality of LED display screen modules of different manufacturers varies. For example, there are differences in color gamut coverage ratio or display effect, which ultimately produce a large color difference in appearance after splicing. In this embodiment, the adjacent display screen parameters obtained in the determinant item address corresponding to the adjacent display screen position include color gamut coverage ratio, peak brightness, saturation and other parameters under the display screen model. These parameters reflect the color display performance of the display screen of this model, and the display screen parameters of multiple models are recorded through a preset database.

[0047] In this embodiment, the powered-on display screen is a replaced display screen. The parameters of each adjacent display screen are compared to determine whether the model is the same. If the models of the adjacent display screens of the powered-on display screen are the same, it is only necessary to consider the color difference relationship between the powered-on display screen and any of the display screens. To avoid color difference, the spliced ​​screens are generally set to the same configuration data when the models are the same; when the number of adjacent display screens in the same row or column is not greater than one, it means that there is only one display screen in the same row or column adjacent to the powered-on display screen, and the powered-on display screen is at the edge of the spliced ​​screen group. At this time, it is only necessary to consider the human eye color effect of the two-to-two comparison between the adjacent display screens and the powered-on display screen; during the power-on process, the powered-on display screen is connected to the HDMI matrix, and after being connected to the host through the HDMI matrix, the model of the powered-on display screen can be obtained, and the color gamut coverage ratio, peak brightness, saturation and other parameters of the model can be obtained in the preset database; the configuration data of the adjacent display screen can be obtained through the control record, and the configuration data closest to the current time is selected in the historical configuration data sent to the adjacent display screen for setting;

[0048] That is, from the time the power is turned on to the time the display screen works stably, the color difference correction is performed on the later spliced ​​or replaced display screens. When there are differences in the color gamut of the display screen itself, the color uniformity on the spliced ​​screen is achieved by adjusting parameters such as brightness and saturation as much as possible; the color gamut standards include sRGB, NTSC, DCI-P3, and Adobe RGB. The color gamut coverage ratio is the ratio of the color that the display screen can display to the standard color gamut area in the color gamut area of ​​the standard. When the color gamut coverage ratio difference of two models of display screens using the same color gamut standard is greater than a certain ratio value, the color defect can be perceived by the human eye, that is, because the total color that the display screen can display is different, when the number of different colors is large enough, the human eye can feel the color difference between the display screens; generally, the color difference value is calculated by considering the brightness, red-green, and yellow-blue differences in the Lab color space. The commonly used color difference value calculation formula is:

[0049]

[0050] Δl is the brightness difference, Δa is the red-green difference, and Δb is the yellow-blue difference. When the color difference ΔE is less than the minimum color difference that the human eye can recognize, the color is uniform and the human eye sees no color difference. In this embodiment, the color values ​​of red, green, and yellow-blue are represented by the display performance difference of the display screen. By calculating the color difference caused by the display performance difference of the saturation combined with the color gamut coverage ratio in the display of the same color, the color value in the color difference calculation formula is replaced, and the color difference value calculation formula used in the lab color space is converted into the first formula in the power-on configuration model; the color gamut determines the color range, and the color gamut value ratio defines the color range that the device can display. Within this range, the device can display colors of various saturations; saturation is a reflection of color quality: within the range determined by the color gamut, the saturation determines the purity and intensity of the color, and even within the same color gamut, colors of different saturations will present completely different visual effects. The difference in visual effects can change the color difference perceived by the human eye. The interaction between the color gamut value ratio and the saturation jointly affects the color display effect. The color reference value set based on the empirical value The color reference value can be selected as a representative of the edge point in the color gamut representation, and the color reference value under the ratio of saturation to color gamut value is converted into a color coordinate value for comparison. The color brightness difference is deepened by increasing the saturation. The greater the saturation, the more vivid the color seen by the human eye. When the brightness is different, the color brightness perceived by the human eye is also different. The display data and the color correction coefficient δ are set according to the empirical value to establish the association between the change of display data such as saturation and brightness and the color change in the human eye. In the configuration data setting of the display, the general brightness ratio value and the saturation ratio value can only be set as the ratio value of integer percentage in software control. For example, when the brightness value is adjusted to 50%, the actual brightness of the display is 50% of the peak brightness. The minimum recognizable color difference value α and the minimum value of the brightness difference that the human eye can recognize β can be set based on the environment where the display is located. In addition to color differences, human eye perception of the screen also includes brightness differences. If the brightness difference of the screen display is too large, the user will feel glaring. Therefore, when adjusting the color difference value, the brightness difference between the display screens must also be considered. In this embodiment, the LED display screens are considered to be operating in accordance with the parameter standards required by the factory, and there are no errors. Furthermore, the parameters that have the greatest impact on color display are generally saturation and brightness, but the display screen has other configuration data that can change the color display effect, such as grayscale and contrast, which can be added to the power-on configuration model to calculate the color difference of the display screen.

[0051] S300, sending the power-on configuration data to the power-on display screen for setting.

[0052] It should be noted that the power-on configuration model calculated in the aforementioned step S200 generally obtains the brightness ratio value range and the saturation ratio value range of the power-on display screen, and the setting ratio in the configuration data setting can generally only be adjusted by integers. When the power-on configuration model is satisfied, the setting value with the lowest brightness ratio value can be selected. While ensuring that the color difference of the spliced ​​screen is small enough, the lowest brightness is used to achieve the lowest energy consumption at the same time; through software adjustment, the brightness ratio value, saturation ratio value, etc. in the power-on configuration data are sent to the power-on display screen, and after setting, the power-on display screen performs color adjustment and display according to the power-on configuration data; by automatically adjusting the configuration data of the power-on display screen when power is turned on, the color difference of different models of display screens can be adaptively corrected. Although further calibration is still required according to the actual color situation of the screen in the subsequent screen color calibration, the aforementioned steps can reduce the color difference of adjacent screens as much as possible to save the time of subsequent correction processing and improve replacement efficiency.

[0053] In this embodiment, by obtaining the configuration data and parameters of the powered-on display screen and the adjacent display screen, during the process of the powered-on display screen being connected and powered on, the adaptive power-on configuration data is calculated through the power-on configuration model, so that the powered-on display screen can display a color effect that is as close as possible to the color of the adjacent display screen, thereby improving the user's viewing experience of the spliced ​​screen and reducing the time required for subsequent color calibration and adjustment.

[0054] The above is a detailed description of the first embodiment of an intelligent power-on method for an LED display screen provided by the present application. The following is a detailed description of the second embodiment of an intelligent power-on method for an LED display screen provided by the present application.

[0055] In this embodiment, a smart power-on method for an LED display screen is further provided. In the aforementioned step S200, after determining whether the number of adjacent display screens in the same row or column is greater than one, the method further includes:

[0056] If yes, then identify the configuration data of the adjacent display screen in the same column and the configuration data of the adjacent display screen in the same row, and construct value interval models respectively. The value interval models are specifically:

[0057]

[0058] Among them, L2 is the peak brightness of the second adjacent display screen, l2 is the brightness ratio value of the second adjacent display screen, C2 is the saturation of the second adjacent display screen, c2 is the saturation ratio value of the second adjacent display screen, and S2 is the color gamut coverage ratio of the second adjacent display screen; then the configuration data and power-on display parameters of any adjacent display screen are substituted into the power-on configuration model respectively to obtain the power-on configuration data that satisfies both the value interval model and the power-on configuration model.

[0059] It should be noted that when the number of adjacent display screens in the same row or column is greater than one, it means that there are two display screens in the same row or column adjacent to the powered-on display screen, and the powered-on display screen is connected to two adjacent display screens in at least a row or a column. At this time, the color effect of the human eye is not simply the color difference of the two adjacent screens, but the color difference is also aggravated by the field of view formed when the multiple screens are connected. Therefore, in the multi-screen connection formed by at least 3 spliced ​​screens, because the powered-on display screen is in the middle of the two adjacent display screens, it is also necessary to ensure the smooth viewing experience of the user in the 3-connected screen. For example, in the case of two adjacent display screens of different models, it is ensured that the color richness of the powered-on display screen in the human eye is between the two adjacent display screens, that is, the color display effect of the 3 screens is distributed in a stepped manner. It is not possible to simply pursue low power consumption with the lowest brightness while meeting the adjacent color difference requirements. After obtaining the parameters of each adjacent display screen of the powered-on display screen, it is determined whether the display screens in the same column or the same row are of the same model. If they are inconsistent, the configuration data is compared. In this embodiment, the adjacent display screen with a larger saturation and color gamut coverage ratio is regarded as an adjacent display screen that displays richer colors in the human eye, and is used as the second adjacent display screen, while the adjacent display screen with a smaller saturation and color gamut coverage ratio is regarded as the first adjacent display screen, and then a value interval model is constructed. The configuration data of the powered-on display screen needs to fall within the value interval model to further maintain the color difference effect when multiple screens are adjacent.

[0060] Furthermore, after constructing the value interval models respectively, it also includes: when the value interval model of adjacent display screens in the same row and the value interval model of adjacent display screens in the same column cannot be satisfied at the same time, compare the number of rows and columns of the spliced ​​screen group, and eliminate the value interval model corresponding to the larger number; when the power-on configuration data satisfies the value interval model, the color difference effect between the powered-on display screen and each adjacent display screen must also be satisfied in the power-on configuration model; and when the powered-on display screen has two adjacent display screens in a row and two adjacent display screens in a column at the same time, and the value interval models of rows and columns cannot be satisfied at the same time, it is necessary to consider the total number of rows and columns of the current spliced ​​screen group. For example, if the number of columns is more, the more adjacent display screens in the same row will form a stronger color contrast field of view, so the value interval model of adjacent display screens in the same row should be selected as the priority.

[0061] The above is a detailed description of an intelligent power-on method for an LED display screen according to the first aspect of the present application. The following is a detailed description of an embodiment of an intelligent power-on system for an LED display screen according to the second aspect of the present application.
