As an optional embodiment, the brightness compensation processing is performed on the bright and dark lines at the splicing position of the first non-rectangular module and the second non-rectangular module by adjusting the correction data of the first splicing pixel and the correction data of the second splicing pixel, and the brightness compensation processing includes: and adjusting the brightness compensation value in the correction data of the first spliced pixel point and the brightness compensation value in the correction data of the second spliced pixel point in equal proportion, and performing brightness compensation processing on the bright and dark lines at the splicing position of the first non-rectangular module and the second non-rectangular module until the bright and dark lines at the splicing position of the first non-rectangular module and the second non-rectangular module reach the preset bright and dark line standard. Through the luminance compensation value in the correction data of the first splicing pixel point and the second splicing pixel point of the equal proportion adjustment, when luminance compensation is carried out, the fact that obvious luminance difference can not appear between the first splicing pixel point and the second splicing pixel point is guaranteed, and then after correction is finished, splicing marks can not be highlighted in the splicing position between the first non-rectangular module and the second non-rectangular module, and therefore better display effect is achieved.

Under the condition that the second splicing edge of the first non-rectangular module in the row-by-row direction corresponds to the splicing edges of other non-rectangular modules (except the first non-rectangular module and the second non-rectangular module), the corresponding brightness compensation processing can be carried out on the splicing pixel points on the second splicing edge of the first non-rectangular module in the row-by-row direction and the splicing pixel points on the splicing edges of the other non-rectangular modules, so that the brightness compensation processing of the splicing lines of the display screen formed by the whole non-rectangular module is completed.

In the related technology, the method for solving the problem of splicing bright and dark lines of the LED flat screen mainly comprises the steps of firstly enabling the distance between adjacent pixel points of each splicing seam to be consistent with the distance between normal pixel points as much as possible by manually adjusting the position of a module, and the method is low in efficiency and cannot completely solve the problem of bright and dark lines; and then the problem of splicing bright and dark lines is solved by adjusting the brightness compensation data in the adjacent pixel point correction data of the two modules. The LED flat screen is formed by splicing a plurality of flat rectangular LED modules with the same area size and the same pixel point arrangement, the correction data file format of each LED box or LED module is consistent, the file name of general correction data represents the address of the LED box or LED module, the first column of numbers in the correction data file represents the number of lines where the pixel points of the box or module are located, the second column of numbers represents the number of lines where the pixel points of the box or module are located, the numbers of the subsequent columns represent brightness compensation data, and the positions of the brightness compensation data of two lines and two lines of spliced pixel points at the edge of all the modules are quickly determined according to the number of lines and the number of columns of the pixel points of the LED module, wherein the two lines and two lines are 4. When the bright and dark lines of the splicing between the modules need to be adjusted, the brightness compensation data of the corresponding edge pixel points in the correction data files of the two adjacent module rows or columns of the splicing seam can be adjusted in equal proportion, so that the brightness of the adjacent pixel points of the splicing seam is changed, and after a satisfactory effect is achieved, the corrected data files are stored in the LED module memories of the corresponding addresses.

However, the method can only solve the problem of splicing bright and dark lines of the LED planar screen, the LED spherical screen is formed by splicing planar LED modules which are mechanically bent, the structural types of the modules are various according to different design methods, the modules are different from a triangular structure to a polygonal structure, and the number of splicing seams of each type of module is possibly different. The pixel point arrangement modes on the surface of the module are different, namely the correction data arrangement formats are different, and according to different correction data writing modes, effective correction data and point-supplementing correction data possibly exist in the correction data of the LED spherical screen module, the effective correction data can be in one-to-one correspondence with the pixel points, the point-supplementing correction data does not have channels corresponding to the pixel points, and the correction display effect of the module is not influenced. Therefore, the positions of the pixel points at the adjacent edges of the two modules at each splicing seam can not be quickly determined through the mode of arranging the pixel points of the modules. It should be noted that the predetermined bright and dark line standard may be a standard that the bright and dark lines cannot be seen, and may be flexibly set according to different requirements.

(3) And determining the position of the pixel point at each splicing position according to the positions of all edge pixel points of the various types of modules. And the computer scans the positions of the pixel points line by line, respectively judges the digital size change of the pixel point column number under the condition that the first and the last pixel points of each line have effective correction data, if the digital size change rule is sequentially reduced or invariable or sequentially increased, continuously executes the steps until the pixel point column number digital size change is judged to be not accordant with the change rule, and then integrates the pixel point positions. And then, continuously executing the steps when the number of the pixel points which do not accord with the change rule is judged to appear until the scanning of all the pixel point numbers is finished. And similarly, executing the conditions that the first and the last pixel points in each row have effective correction data respectively, executing the steps until the scanning of all the pixel point rows is finished, and finally obtaining the collection of the pixel point positions of all the splicing positions.
