TECHNICAL FIELD

[0001] The present application relates to the display field, and in particular, to a display unit correction method and device and electronic equipment. BACKGROUND

[0002] A light emitting diode (LED) display screen is a flat panel display device composed of LED dot matrix. Generally, an LED display screen is composed of a plurality of display units. The display units can be spliced into an LED display screen after uniformity correction.

[0003] However, after the display units are spliced into an LED display screen, bright lines in units of display units appear on the screen, which affects the display quality of the LED display screen.

[0004] Currently, there is no effective solution to the above problem. SUMMARY

[0005] Embodiments of the present application provide a display unit correction method, device and electronic equipment to at least solve the technical problem that bright lines appear after display units are spliced into an LED display screen after correction, which leads to poor display quality of the LED display screen.

[0006] According to an aspect of an embodiment of the present application, a display unit correction method is provided, including: obtaining first data information of a first display unit, the first data information being data information of the first display unit in a first lighting state; obtaining second data information of the first display unit, the second data information being data information of the first display unit in a second lighting state, a lighting area in the first lighting state being a proper subset of a lighting area in the second lighting state; and obtaining a correction coefficient of an edge light point of the first display unit according to the first data information and the second data information.

[0007] By obtaining the correction coefficient of the edge light point of the display unit in the LED display screen, the edge light point is adjusted according to the correction coefficient, so that the brightness of the entire display unit is uniform after splicing, and bright lines do not appear after the display unit is spliced. Thus, the technical problem that bright lines appear after display units are spliced into an LED display screen after correction, which leads to poor display quality of the LED display screen, is solved.

[0008] Optionally, the lighted area in the first lighted state is a central area of the first display unit, and the lighted area in the second lighted state is the entire first display unit; or the lighted area in the first lighted state is a first area of the first display unit, and the lighted area in the second lighted state is a second area of the first display unit, wherein the first area is a proper subset of the second area.

[0009] In the implementation of the lighted area in the first lighted state being a proper subset of the lighted area in the second lighted state, one display unit can be used to simulate the lighted area in the first lighted state and the lighted area in the second lighted state, so as to realize the lighted area in the first lighted state being a proper subset of the lighted area in the second lighted state by using as few display units as possible.

[0010] Optionally, the lighted area in the first lighted state is the first display unit, and the lighted area in the second lighted state is a display screen including 3*3 display units, and the first display unit is located at the center of the display screen; or the lighted area in the first lighted state is the first display unit, and the lighted area in the second lighted state is a central area of the display screen including 3*3 display units, and the first display unit is located at the center of the display screen and is a proper subset of the central area of the display screen; or the lighted area in the first lighted state is the first display unit, and the lighted area in the second lighted state is at least a partial area of the display screen including at least two display units, and the first display unit is a proper subset of the at least partial area of the display screen.

[0011] In the implementation of the lighted area in the first lighted state being a proper subset of the lighted area in the second lighted state, at least two display units can be used to simulate the lighted area in the first lighted state and the lighted area in the second lighted state. The use of at least two display units to realize the lighted area in the first lighted state being a proper subset of the lighted area in the second lighted state has the advantages of clear logic and simple operation.

[0012] Optionally, the correction coefficient of the edge light point of the first display unit is obtained according to the first data information and the second data information, including: obtaining the correction coefficient of the edge light point of the first display unit according to a proportional relationship between data information corresponding to a first light point in the first data information and data information of the first light point in the second data information, wherein the first light point is a light point in the first display unit.

[0013] In the acquisition of the correction coefficient, a proportional relationship between data of the same lamp point in the lighted area in the first lighted state and the lighted area in the second lighted state is adopted to obtain the correction coefficient of the edge lamp point. The correction coefficient obtained according to the proportional relationship can be applied to the processing of various to-be-corrected data, for example, can be used for the correction of the collected initial data information, or can be used for the correction of the initial correction coefficient, thereby realizing the convenience of subsequent use of the correction coefficient.

[0014] Optionally, the correction coefficient of the edge lamp point of the first display unit is obtained according to a proportional relationship between data information corresponding to the first lamp point in the first data information and data information of the first lamp point in the second data information, including: in the case that the first lamp point is a B i * j lamp point, the correction coefficient of the B i * j lamp point is obtained according to a proportional relationship between data information corresponding to the B i * j lamp point in the first data information and data information of the B i * j lamp point in the second data information, wherein the B i * j lamp point represents a lamp point of the i-th row and the j-th column of the edge of the first display unit; or, in the case that the first lamp point is a non-edge lamp point of the first display unit, the correction coefficient of the non-edge lamp point simulated as an edge lamp point is obtained according to a proportional relationship between data information corresponding to the non-edge lamp point in the first data information and data information of the non-edge lamp point in the second data information; and the correction coefficient of the edge lamp point of the first display unit is obtained according to the correction coefficient of the non-edge lamp point.

[0015] By using the above processing, the correction coefficient of the edge lamp point can be directly obtained according to a proportional relationship between data of the edge lamp point in the lighted area in the first lighted state and the lighted area in the second lighted state, or the correction coefficient of the non-edge lamp point can be obtained according to a proportional relationship between data of the non-edge lamp point in the lighted area in the first lighted state and the lighted area in the second lighted state, and then the correction coefficient of the edge lamp point of the first display unit is obtained according to the correction coefficient of the non-edge lamp point. By using the above direct or indirect acquisition method of the correction coefficient of the edge lamp point, various acquisition methods are provided, so that the specific scene can be flexibly selected.

[0016] Optionally, the correction coefficient of the edge lamp point is obtained according to the first data information and the second data information, and the obtaining includes one of the following: determining the correction coefficient of the edge lamp point point by point; selecting a representative lamp point from the edge region, and determining the correction coefficient of the lamp point in the entire edge region according to the correction coefficient of the representative lamp point; and determining the correction coefficient of the lamp point in a corresponding row or column according to the average value of the correction coefficients of the lamp points in the row or column in units of row or column in the edge region.

[0017] When the correction coefficient of the edge lamp point is obtained, the method can be different according to the number of edge lamp points used to determine the correction coefficient. For example, the correction coefficient of all edge lamp points can be determined point by point, and the correction coefficient of all edge lamp points is determined, so the method is accurate. The correction coefficient of the representative lamp point can be determined, and only the correction coefficient of the representative lamp point needs to be calculated, so only the data of the representative lamp point needs to be collected and processed, and the calculation resources can be effectively saved. When the correction coefficient of the lamp point in a corresponding row or column is determined according to the average value of the correction coefficients of the lamp points in the row or column in units of row or column in the edge region, the average value of the row or column is used, which is between the method of determining the correction coefficient of each lamp point and the method of determining the correction coefficient of the representative lamp point, so a better balance between accuracy and efficiency can be obtained.

[0018] Optionally, the method further includes: obtaining the target correction coefficient of the first display unit according to the correction coefficient of the edge lamp point; or uploading the correction coefficient of the edge lamp point to the first display unit.

[0019] After the correction coefficient of the edge lamp point is obtained, the correction coefficient can be directly stored, or the target correction coefficient of the first display unit can be obtained according to the correction coefficient of the edge lamp point, and the target correction coefficient is stored. Therefore, when the method is applied, the correction coefficient or the target correction coefficient obtained according to the correction coefficient can be selected flexibly according to the specific needs.

[0020] Optionally, the target correction coefficient of the first display unit is obtained according to the correction coefficient of the edge lamp point, and the obtaining includes: correcting the initial correction coefficient of the first display unit according to the correction coefficient of the edge lamp point to obtain the target correction coefficient of the first display unit; or correcting the initial data information collected by the first display unit according to the correction coefficient of the edge lamp point to obtain corrected data information, and obtaining the target correction coefficient of the first display unit according to the corrected data information and the target data information.

[0021] The initial correction coefficient is processed to obtain the target correction coefficient, which is simple and direct. The target correction coefficient is generated by directly adjusting the collected bright chroma data according to the correction coefficient. Since the initial correction coefficient is not needed, the calculation resource can be effectively saved, and the efficiency of obtaining the target correction coefficient is improved.

[0022] Optionally, the first display unit comprises at least one sample display unit, and the method further comprises: obtaining a common correction coefficient of the edge light points according to the correction coefficient of the edge light points of each sample display unit in the at least one sample display unit, and the common correction coefficient of the edge light points is used to correct the edge light points of the display units in the same batch.

[0023] According to the correction coefficient of the edge light points of the sample display unit, the common correction coefficient of the edge light points is obtained, so that the correction of the edge light points of the display units in the same batch is applied, the calculation processing of the edge light points of the display units in the same batch is effectively saved, and the efficiency of obtaining the correction coefficient of the display units in the same batch is effectively improved.

[0024] Optionally, the method further comprises: obtaining a target correction coefficient of at least one display unit in the same batch according to the common correction coefficient of the edge light points, or uploading the common correction coefficient of the edge light points to at least one display unit in the same batch.

[0025] Therefore, when the common correction coefficient of the edge light points is applied in specific applications, it can be flexibly selected whether to store and apply the common correction coefficient of the edge light points or to store and apply the target correction coefficient of the display units in the same batch obtained according to the common correction coefficient of the edge light points according to specific requirements.

[0026] Optionally, the obtaining of the target correction coefficient of at least one display unit in the same batch according to the common correction coefficient of the edge light points comprises: correcting the initial correction coefficient of the at least one display unit according to the common correction coefficient of the edge light points to obtain the target correction coefficient of the at least one display unit, or correcting the initial data information collected by the at least one display unit according to the common correction coefficient of the edge light points to obtain corrected data information, and obtaining the target correction coefficient of the at least one display unit according to the corrected data information and target data information.

[0027] For at least one display unit of the same batch, the initial correction coefficient is processed by using the correction coefficient of the common edge lamp point to obtain the target correction coefficient, which is simple and direct; and the collected initial data information is directly adjusted according to the correction coefficient of the common edge lamp point to obtain the corrected data information, and then the target correction coefficient is generated, and since the initial correction coefficient is not obtained, the calculation resources can be effectively saved and the efficiency of obtaining the target correction coefficient is improved.

[0028] According to another aspect of the embodiment of the present application, a display unit is provided, which comprises M rows and N columns of lamp points, and the brightness value of the edge lamp points of at least one edge of the display unit is less than that of the lamp points in the central region of the display unit after the display unit is lighted up, wherein M and N are positive integers, and the display unit stores a target correction coefficient or a correction coefficient, wherein the target correction coefficient is obtained by processing the correction coefficient according to any one of the above methods, and the correction coefficient is obtained according to any one of the above methods.

[0029] After the display unit is lighted up, the brightness value of the at least one edge lamp point is less than that of the lamp points in the central region, and the display unit stores the correction coefficient obtained by any one of the above methods or the target correction coefficient obtained by processing the correction coefficient obtained by any one of the above methods.

It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0053] Embodiment 1

[0054] In the background art, it is mentioned that after the display units are spliced into an LED display screen, we will find that there are bright lines on the screen in units of display units. After analysis, this is because after the LED display screen is lit up, other units around each display unit will contribute to the brightness of the edge light points, and when the display unit is corrected alone, there is no such brightness contribution around each display unit, so this splicing bright line phenomenon occurs, thereby seriously affecting the display quality. The present scheme specifically describes how to solve this problem.

[0055] According to an embodiment of the present application, an embodiment of a display unit correction method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from here.

[0056] The present application provides a display unit correction method as shown in Figure 1 . Figure 1 is a flowchart of a display unit correction method according to Embodiment 1 of the present application, as shown in Figure 1 , the method comprises the following steps:

[0057] Step S102, obtaining first data information of the first display unit, the first data information being data information of the first display unit in a first lighting state;

[0058] Step S104, obtaining second data information of the first display unit, the second data information being data information of the first display unit in a second lighting state, the lighting area in the first lighting state being a proper subset of the lighting area in the second lighting state;

[0059] Step S106, obtaining a correction coefficient of the edge light points of the first display unit according to the first data information and the second data information.

[0060] Through the above steps, by obtaining the correction coefficient of the edge light points of the first display unit, adjusting the edge light points of the first display unit according to the correction coefficient, the brightness of the entire display unit is uniform after splicing, avoiding the appearance of bright lines after splicing the display unit, thereby solving the technical problem that the display quality of the LED display screen is poor due to the appearance of the splicing bright line phenomenon when the display unit is spliced into an LED display screen after being corrected in the related art.

[0061] As an optional example, the first lighting state can be used to simulate the lighting state before the first display unit is spliced, and the second lighting state can be used to simulate the lighting state after the first display unit is spliced. The correction coefficient of the edge light points of the first display unit can be obtained by the change of the data information before and after the first display unit is spliced.

[0062] In addition, it should be noted that the first display unit mentioned above refers to a unit that can be used to splice into a display screen, that is, a region on the spliced display screen. The form of the display unit can be various, for example, it can be an LED box, an LED module, an LED module, an LED lamp panel, etc. The display unit includes an edge region and a center region, wherein the edge region is the peripheral region of the display unit. The display unit includes a plurality of rows and a plurality of columns of matrix light points, and the peripheral region of the display unit is a predetermined number of rows or a predetermined number of columns of light points in the peripheral part of the matrix. Wherein the size of the predetermined number of rows or the predetermined number of columns can be determined according to the manufacturing accuracy of the specific LED light point. The center region is the region in the display unit except the edge region. The light points in the edge region are edge light points, and the light points in the center region are center light points.

[0063] As an optional embodiment, the first data information and the second data information can include at least one of a plurality of information, such as luminance value information, chrominance value information (luminance chrominance value information), X stimulus value information (red primary color stimulus amount information), Y stimulus value information (green primary color stimulus amount information), Z stimulus value information (blue primary color stimulus amount information), initial correction coefficient information, etc. It should be understood that as long as the information can be used to calculate the influence of the adjacent light points on the light points, it belongs to the protection scope of the present application.

[0064] Wherein, the luminance value information can be the luminance value data of the LED light point. For example, the first data information can be the luminance value data corresponding to the lighted area in the first lighted state, and the second data information can be the luminance value data corresponding to the lighted area in the second lighted state.

[0065] Wherein, the X stimulus value information can be the X stimulus value of the LED light point under the X filter.

[0066] Wherein, the initial correction coefficient information can be the correction coefficient information before the edge light point is corrected. The initial correction coefficient can also be obtained in various ways, for example, a computer device can be connected to the corresponding display unit, and the computer device can send related collection instructions, calculation instructions and data processing instructions to the related collection device to obtain the initial correction coefficient of the lighted area in the first lighted state and the initial correction coefficient of the lighted area in the second lighted state.

[0067] As an optional embodiment, the lighted area in the first lighted state is a proper subset of the lighted area in the second lighted state, that is, the lighted area in the second lighted state contains but is different from the lighted area in the first lighted state. Optionally, in the above relationship of the lighted area of the lighted state, the following implementation modes can be included but are not limited to.

[0068] Option 1: can be based on a display unit to achieve.

[0069] Specifically, the lighting area in the first lighting state is the first region of the first display unit, and the lighting area in the second lighting state is the second region of the first display unit, wherein the first region is a proper subset of the second region.

[0070] For example, the lighting area in the first lighting state is the central region of the first display unit, and the lighting area in the second lighting state is the entire first display unit. Figure 2a is a schematic diagram of lighting a central region of a display unit according to an optional embodiment 1 of the present application; Figure 2b is a schematic diagram of lighting a display unit according to an optional embodiment 1 of the present application. As an optional example, Figure 2a and Figure 2b may be used to illustrate the lighting area in the first lighting state and the lighting area in the second lighting state, respectively.

[0071] For another example, the lighting area in the first lighting state is the region of the first number of columns (or rows) of lamp points in the first display unit, and the lighting area in the second lighting state is the region of the second number of columns (or rows) of lamp points in the first display unit, wherein the first number is less than the second number, for example, the second number of columns can be composed of the first number of columns plus the number of columns of edge lamp points. Figure 3a is a schematic diagram of lighting a first region of a display unit according to an optional embodiment 2 of the present application, Figure 3b is a schematic diagram of lighting a second region of a display unit according to an optional embodiment 2 of the present application. As an optional example, Figure 3a and Figure 3b may be used to illustrate the lighting area in the first lighting state and the lighting area in the second lighting state, respectively.

[0072] Option 2: can be based on at least two display units to achieve.

[0073] Specifically, the lighting area in the first lighting state is the first display unit, and the lighting area in the second lighting state is at least a part of the display screen, and the display screen includes at least two display units, and the first display unit is a proper subset of at least a part of the display screen. That is, the first lighting state simulates a small area before splicing, and the second lighting state simulates a large area after splicing.

[0074] For example, the lighted area in the first lighted state is the first display unit, and the lighted area in the second lighted state is the display screen, which includes 3*3 display units, and the first display unit is located in the center of the display screen. This mode can be considered as: the lighted area in the first lighted state is the first display unit, and the lighted area in the second lighted state is the area corresponding to the 3*3 display units centered on the first display unit. Figure 4a is a schematic diagram of lighted display units according to an optional embodiment three of the present application, Figure 4b is a schematic diagram of lighted display screen including 3*3 display units according to an optional embodiment three of the present application, as an optional example, Figure 4a and Figure 4b may be used to illustrate the lighted area in the first lighted state and the lighted area in the second lighted state, respectively.

[0075] For another example, the lighted area in the first lighted state is the first display unit, and the lighted area in the second lighted state is the central area of the display screen, which includes 3*3 display units, and the first display unit is located in the center of the display screen, and the first display unit is a proper subset of the central area of the display screen. For example, the lighted area in the first lighted state is the first display unit, and the lighted area in the second lighted state is the first display unit and the edge light points of part or all of the other display units spliced with the first display unit. Figure 5a is a schematic diagram of lighted display units according to an optional embodiment four of the present application, Figure 5b is a schematic diagram of lighted display units and their surrounding areas according to an optional embodiment four of the present application, Figure 5a and Figure 5b may be used to illustrate the lighted area in the first lighted state and the lighted area in the second lighted state, respectively.

[0076] For another example, the lighted area in the first lighted state is the first display unit, and the lighted area in the second lighted state is part of the other display units spliced with the first display unit. Figure 6a is a schematic diagram of lighted display units according to an optional embodiment five of the present application, Figure 6b is a schematic diagram of lighted display units and their adjacent display units according to an optional embodiment five of the present application, Figure 6a and Figure 6b may be used to illustrate the lighted area in the first lighted state and the lighted area in the second lighted state, respectively.

[0077] It should be noted that the above-mentioned implementation modes of the lighted area in the first lighted state and the lighted area in the second lighted state are only examples, and other various combinations capable of determining the influence of the edge light points also belong to the present application, which will not be illustrated one by one.

[0078] As an optional embodiment, when the correction coefficient of the edge lamp point of the first display unit is obtained according to the first data information and the second data information, the correction coefficient of the edge lamp point of the first display unit can be obtained according to a proportional relationship between the data information corresponding to the first lamp point in the first data information and the data information of the first lamp point in the second data information, wherein the first lamp point is a lamp point in the first display unit. Optionally, the first lamp point can include but is not limited to the following cases.

[0079] Case one: the first lamp point can be an edge lamp point in the first display unit.

[0080] Specifically, the correction coefficient of the edge lamp point of the first display unit can be obtained according to a proportional relationship between the data information of the edge lamp point in the first data information and the data information of the edge lamp point in the second data information.

[0081] Suppose the first lamp point is an edge lamp point B i * j in the first display unit, the correction coefficient of B i * j can be obtained according to a proportional relationship between the data information corresponding to B i * j in the first data information and the data information of B i * j in the second data information, wherein the B i * j th lamp point represents a lamp point in the i-th row and the j-th column of the edge of the first display unit.

[0082] Case two: the first lamp point can be a non-edge lamp point of the first display unit.

[0083] Specifically, the correction coefficient of the edge lamp point of the first display unit can be obtained according to a proportional relationship between the data information of the non-edge lamp point in the first data information and the data information of the non-edge lamp point in the second data information.

[0084] In the case that the first lamp point is a non-edge lamp point of the first display unit, the correction coefficient of the non-edge lamp point simulated as an edge lamp point can be obtained according to a proportional relationship between the data information corresponding to the non-edge lamp point in the first data information and the data information of the non-edge lamp point in the second data information; and the correction coefficient of the edge lamp point of the first display unit can be obtained according to the correction coefficient of the non-edge lamp point. In order to obtain the correction coefficient of the edge lamp point, the correction coefficient of the non-edge lamp point simulated as an edge lamp point can also be obtained in the manner of simulating the edge lamp point by the non-edge lamp point, and then the correction coefficient of the non-edge lamp point simulated as an edge lamp point is taken as the correction coefficient of the edge lamp point. For example, the first lamp point is Figure 2aThe edge light point of the lighting area is the first light point, but the first light point is a non-edge light point relative to the whole display unit. The correction coefficient of the edge light point of the display unit can be obtained based on the correction coefficient of the first light point.

[0085] As an optional embodiment, when the correction coefficient of the edge light point is obtained, various methods can be used. For example, at least one of the following methods can be used:

[0086] 1) The correction coefficient of each light point in the edge area of the display unit is determined point by point.

[0087] 2) A representative light point is selected from the edge area of the display unit, and the correction coefficient of the representative light point is used to determine the correction coefficient of the light points in the whole edge area.

[0088] 3) In the edge area of the display unit, the correction coefficient of the light points in a row or a column is determined by the average value of the correction coefficients of the light points in the row or the column.

[0089] When the correction coefficient of each light point in the edge area of the display unit is determined point by point, although data collection and calculation processing need to be performed separately for each light point, the correction coefficient obtained for each light point is true and accurate. When a representative light point is selected from the edge area of the display unit, and the correction coefficient of the representative light point is used to determine the correction coefficient of the light points in the whole edge area, the representative light point is selected, and the correction coefficient of the representative light point is used as the correction coefficient of the light points in the whole edge area. The selection of the representative light point is important, which can be obtained based on historical experience or multiple measurements. By selecting the representative light point, only the correction coefficient of the representative light point needs to be calculated, so only the data collection and calculation processing of the representative light point are needed, which can effectively save the calculation resources. When the correction coefficient of the light points in a row or a column is determined by the average value of the correction coefficients of the light points in the row or the column in the edge area of the display unit, the average value is taken in units of rows or columns, which is between the way of determining the correction coefficient of each light point and the way of selecting the representative light point to determine the correction coefficient, so a better balance between accuracy and efficiency can be obtained.

[0090] As an optional example, the method can further include:

[0091] S108 obtains the target correction coefficient of the first display unit according to the correction coefficient of the edge light point; or uploads the correction coefficient of the edge light point to the first display unit.

[0092] Specifically, the target correction coefficient can be obtained according to the correction coefficient, so as to store the target correction coefficient in the first display unit, or the correction coefficient can be uploaded to the first display unit, so as to subsequently use the correction coefficient to obtain the target correction coefficient, etc.

[0093] Further optionally, obtaining the target correction coefficient of the first display unit according to the correction coefficient of the edge light point can at least include the following two kinds:

[0094] The first kind: S108a corrects the initial correction coefficient of the first display unit according to the correction coefficient of the edge light point to obtain the target correction coefficient of the first display unit. Optionally, when the target correction coefficient of the display unit is obtained according to the correction coefficient, the correction coefficient can be used to adjust the correction coefficient of the edge light point, and the correction coefficient of the light point in other areas is not affected and does not need to be adjusted. Therefore, the difference between the target correction coefficient and the initial correction coefficient can only be that the correction coefficient of the edge light point is adjusted, and the correction coefficient of the edge light point in the target correction coefficient is obtained by adjusting the correction coefficient of the edge light point in the initial correction coefficient according to the correction coefficient.

[0095] When obtaining the initial correction coefficient of the first display unit, since the display unit includes edge light points and center light points, the initial correction coefficient includes the first correction coefficient of the edge light point and the second correction coefficient of the center light point. The edge light point is the light point of the edge region of the display unit, and the center light point is the light point of the center region of the display unit except the edge region. It should be noted that there are many ways to obtain the initial correction coefficient of the display unit of the LED display screen, for example, the following method can be used: first, the image of the display unit is collected by the camera, wherein the image is an image including red, green and blue colors; the brightness data of each light point in the display unit is obtained according to the above image; the brightness correction coefficient of each light point is generated according to the initial brightness data (actual brightness data) and the target brightness data of each light point, and the brightness correction coefficient is uploaded to the correction unit for saving and application.

[0096] The second kind: S108a corrects the initial data information collected by the first display unit according to the correction coefficient of the edge light point to obtain the corrected data information, and obtains the target correction coefficient of the first display unit according to the corrected data information and the target data information. Optionally, when the initial data information is corrected according to the correction coefficient, the correction coefficient can be used to adjust the data information of the edge light point, and the data information of the light point in other areas is not affected and does not need to be adjusted. Therefore, the difference between the corrected data information and the initial data information can only be that the data information of the edge light point is adjusted.

[0097] For example, after the initial brightness value of the first display unit is collected, the initial brightness value of the edge light point of the first display unit is directly corrected according to the correction coefficient to obtain the corrected brightness value information, and the target correction coefficient is generated according to the corrected brightness value information and the target brightness value information.

[0098] The correction coefficient of the edge lamp point can be used to represent the influence of the surrounding lamp points on the edge lamp point after the display units are spliced. In the related application of the LED display screen, the lamp points on the other display units around each display unit will have a brightness contribution to the edge lamp point of the display unit, and thus will cause a bright line at the splicing position of the LED display screen. To solve the influence caused by the brightness contribution, the influence of the brightness contribution on the edge lamp point of the display unit can be obtained, which can be represented in various ways, for example, in the way of the correction coefficient mentioned above, and of course, other specific data can also be used. The correction coefficient of the edge lamp point can be obtained by adjusting the corresponding correction coefficient (or directly adjusting the initial data collected), so that the LED display screen can avoid the bright line problem caused by the above reasons after being spliced.

[0099] It should be noted that the method in the present application can be applied to various application scenarios. As an optional example, the method of the present application can be applied before the display unit is shipped. For example, the correction coefficient can be generated by using the embodiment of the present application before the display unit is shipped, so that the display unit will not cause a bright line after being spliced into a display screen after being shipped. Further, the above operation can be performed on each display unit before being shipped, or a sampling method can be used to perform the above operation on the sample display unit, and the generated correction coefficient is applied to all display units (all display units of the same batch). That is, the sample display unit is operated according to the above method, and the common correction coefficient of the edge lamp point is generated. The common correction coefficient of the edge lamp point is applied to the display units of the same batch.

[0100] As an optional example, the sample display unit can be one or more. That is, the first display unit in the above can include at least one sample display unit.

[0101] For example, the first display unit can include one sample display unit. After obtaining the correction coefficient of the sample display unit, the correction coefficient can be used as the common correction coefficient of the edge lamp point and applied to other display units of the same batch.

[0102] For another example, the first display unit can include multiple sample display units. The correction coefficient of each sample display unit is obtained by using the above method, and then the common correction coefficient of the edge lamp point is obtained according to the correction coefficient of each sample display unit, and then the common correction coefficient of the edge lamp point is applied to the display units of the same batch. Optionally, the correction coefficients obtained by multiple samplings can be averaged to obtain the common correction coefficient of the edge lamp point.

[0103] It should be understood that, if the correction coefficient of the common edge light point is obtained by using the sampling method, the application manner of the correction coefficient and / or the corresponding processing and storage can refer to the description of S108 and S108a above, which will not be repeated here for brevity.

[0104] That is, the above-mentioned method of obtaining the correction coefficient of the edge light point of the first display unit can be applied to the correction of the edge light point of other display units in the same batch as the first display unit. For example, when correcting the edge light point of the display unit in the same batch, the correction coefficient of the common edge light point can be determined first. For example, a sample display unit can be selected from the display units in the same batch, and the sample display unit can perform the same processing as the first display unit to obtain the correction coefficient of the common edge light point. The correction coefficient of the common edge light point is used to correct the edge light point of the display unit in the same batch.

[0105] As an optional embodiment, after obtaining the correction coefficient of the common edge light point, the correction coefficient of the common edge light point can be applied similarly to the processing of the first display unit. For example, the target correction coefficient of at least one display unit in the same batch can be obtained according to the correction coefficient of the common edge light point; or, for example, the correction coefficient of the common edge light point can be uploaded to at least one display unit in the same batch. The storage of the target correction coefficient of at least one display unit and the correction coefficient of the common edge light point is similar to the processing of the first display unit, which will not be repeated here.

[0106] As an optional embodiment, the target correction coefficient of at least one display unit in the same batch can be obtained according to the correction coefficient of the common edge light point, which can also be obtained in various ways. For example, the correction coefficient of at least one display unit is corrected according to the correction coefficient of the common edge light point to obtain the target correction coefficient of at least one display unit; or, the initial data information collected by at least one display unit is corrected according to the correction coefficient of the common edge light point to obtain corrected data information, and the target correction coefficient of at least one display unit is obtained according to the corrected data information and the target data information. By adjusting the edge light point of the display unit in the same batch through each sample display unit, the correction of the edge light point of the display unit in the same batch can be quickly and effectively realized.

[0107] As an optional embodiment, after the correction coefficient of the edge lamp point is acquired, the correction coefficient can be directly stored when it is applied, or the target correction coefficient can be obtained according to the correction coefficient of the edge lamp point, and then the target correction coefficient is stored. It should be noted that whether the above correction coefficient is stored or the target correction coefficient obtained according to the correction coefficient is stored, it can be stored by hanging a memory on the display unit, or it can be directly uploaded to the control device corresponding to the display unit, for example, to the receiving card corresponding to the display unit, for the receiving card to control the display of the display unit.

[0115] 2) When all the display units are lit, the colorimetric data of the nth lamp on the edge of the central region is Lum' n ;

[0125] It should be noted that the correction coefficient is calculated in the same way as in the first alternative embodiment, but it should be pointed out that in this alternative embodiment two, according to the bright chrominance data of the first region, the edge of the nth light point of the first region, the correction coefficient Coef n .

[0166] In addition to the point-by-point calculation method of the above various optional implementations, the average value of each row (column) of lamp points can also be calculated, that is, the same correction coefficient is used for each row (column).

[0167] In the above various optional embodiments, either the data of three different colors after passing through the XYZ three filters of the camera can be collected to generate nine sets of correction coefficients, or only the data of one color after passing through one filter can be collected to generate one set of correction coefficients, and the specific LED display screen is flexibly selected.
