It should be noted that, in the present embodiment, in each of the plurality of display screen segments generated for one initial LED display screen, any display area of the initial LED display screen has a corresponding display screen segment to represent the display area.
Step S30: and establishing an index relation between the display screen blocks, the corresponding initial LED display screens and the initial correction coefficients according to the position corresponding relation between the display screen blocks and the initial LED display screens.
As shown in fig. 2 and fig. 3, this embodiment lists the structures of an initial LED display screen (a) and an initial LED display screen (B), where the initial LED display screen (a) is composed of 8 boxes including a1, a2, A3, a4, a5, a6, a7, and A8, and the initial LED display screen (B) is composed of 4 boxes including B1, B2, B3, and B4. With the box as a block unit (in the following embodiments, the box is also used as a block unit, and those skilled in the art can set other unit structures as block units, which should not be construed as a limitation of the scope of the present invention), through the process of step S20, 8 display screen blocks are generated for the initial LED display screen (a), and 4 display screen blocks are generated for the initial LED display screen (B).
An index relationship between the display screen blocks and the corresponding initial LED display screens and the initial correction coefficients is established through step S30, namely, the 8 display screen blocks of the initial LED display screens (A) are in one-to-one correspondence with the 8 boxes of the initial LED display screens (A). Preferably, the index relationship in the embodiment of the present invention is a row-column coordinate of an area corresponding to an initial LED display screen represented by a display screen block, and the embodiment uses a preset frame to represent the display screen block for displaying on the display interface according to the index relationship. The application sets that the square represents the display screen block divided by the box body, 8 display screen blocks of the initial LED display screen (A) are displayed as shown in figure 4, the display screen sub-block A (1,1) corresponds to a box body A1 of an initial LED display screen (A), the display screen sub-block A (1,2) corresponds to a box body A2 of the initial LED display screen (A), the display screen sub-block A (1,3) corresponds to a box body A3 of the initial LED display screen (A), the display screen sub-block A (1,4) corresponds to a box body A4 of the initial LED display screen (A), the display screen sub-block A (2,1) corresponds to a box body A5 of the initial LED display screen (A), the display screen sub-block A (2,2) corresponds to a box body A6 of the initial LED display screen (A), the display screen sub-block A (2,3) corresponds to a box body A7 of the initial LED display screen (A), and the display screen sub-block A (2,4) corresponds to a box body A8 of the initial LED display screen (A). The 4 display screen blocks of the initial LED display screen (B) are displayed as shown in fig. 5, wherein the display screen blocks B (1,1) correspond to the box body B1 of the initial LED display screen (B), the display screen blocks B (1,2) correspond to the box body B2 of the initial LED display screen (B), the display screen blocks B (2,1) correspond to the box body B3 of the initial LED display screen (B), and the display screen blocks B (2,2) correspond to the box body B4 of the initial LED display screen (B).
Step S40: and storing the display screen blocks, the initial correction coefficients and the index relation.
And locally storing the display screen blocks, the initial correction coefficient and the index relation.
Step S50: according to the LED display screen to be corrected and a preset block matching strategy, selecting target display screen blocks forming the LED display screen to be corrected from the display screen blocks, and reading an index relation and a corresponding initial correction coefficient associated with the target display screen blocks.
The purpose of the embodiment of the invention is to generate a suitable target correction coefficient for the LED display screen to be corrected, and the LED display screen to be corrected of the embodiment of the invention has correlation with the structures of a plurality of initial LED display screens, so that the target correction coefficient is obtained after the initial correction coefficient is subjected to certain processing, and the correction coefficient of the LED display screen to be corrected is not directly calculated through correction software. In the embodiment of the invention, when each initial LED display screen generates the corresponding display screen block, each display screen block corresponds to one box body of the initial LED display screen, the display screen blocks can be associated with the unique product numbers of the box bodies, so that each box body uniquely corresponds to one display screen block, if the LED display screen to be corrected is composed of the box bodies in some initial LED display screens, the display screen blocks corresponding to the box bodies forming the LED display screen to be corrected can be selected from a plurality of display screen blocks through the block matching process of the step S50, and the display screen blocks are used as target display screen blocks. And correspondingly finding out the initial correction coefficient of the corresponding initial LED display screen through the index relation associated with each target display screen block.
Preferably, the method adopts a probe card mode to determine, detects the coordinate position of each box body or module, each box body or module has a corresponding position, so that the box body or module is conveniently checked to be changed, for example, the initial LED display screen is composed of a row of box bodies and three columns of box bodies, the box body positions can be 1-1, 1-2 and 1-3, and when the box body of 1-1 is changed, the box body of 1-1 can be determined to be changed by the box bodies of 1-2 and 1-3.
In the implementation process of the invention, two conditions exist in the relation between the LED display screen to be corrected and the initial LED display screen, the first one is as follows: the target display screen block of the LED display screen to be corrected is the same as the display screen block of a certain initial LED display screen; and the second method comprises the following steps: the target display screen block of the LED display screen to be corrected is not identical to the display screen block of a certain initial LED display screen. Step S60 is executed for determination.
Step S60: and judging whether the target display screen block of the LED display screen to be corrected is the same as the display screen block of a certain initial LED display screen. If so, go to step S70, otherwise, go to step S80.
Step S70: and generating a target correction coefficient according to the initial correction coefficient of the initial LED display screen.
When the target display screen partition of the LED display screen to be corrected is completely the same as the display screen partition of a certain initial LED display screen, it is indicated that the target correction coefficient required by the LED display screen to be corrected is only related to the initial correction coefficient of the initial LED display screen, and the data volume of the target correction coefficient is the same as that of the initial correction coefficient, and at this time, the target correction coefficient is directly generated according to the initial correction coefficient of the initial LED display screen.
Step S80: and splitting and/or assembling the initial correction coefficient according to the index relation of the target display screen blocks to generate a target correction coefficient.
When the target display screen block of the LED display screen to be corrected is not completely the same as the display screen block of a certain initial LED display screen, the structure of the LED display screen to be corrected is separated, replaced and combined relative to the structure of the initial LED display screen, so that the initial correction coefficient needs to be split and/or assembled according to the target display screen block and the index relation, and the target correction coefficient can be generated.
And after the target correction coefficient is generated, sending the target correction coefficient to a receiving card corresponding to the LED display screen to be corrected, and correcting the display screen to be corrected through the target correction coefficient when the display screen to be corrected displays.
Specifically, as shown in fig. 6, in the embodiment of the present invention, if the target display screen segment of the LED display screen to be corrected is identical to the display screen segment of a certain initial LED display screen, then,
step S101: judging whether a target display screen block in the LED display screen to be corrected has position change relative to a display screen block in the initial LED display screen; if not, step S102 is executed, and if yes, step S103 is executed.
Step S102: the initial correction coefficient is taken as a target correction coefficient.
If the target display screen block in the LED display screen to be corrected does not have position change relative to the display screen block in the initial LED display screen, it indicates that the box body in the LED display screen to be corrected is identical in position to the box body of the initial LED display screen, that is, the LED display screen to be corrected is the original initial LED display screen, and no change is made to the structure of the original initial LED display screen, so that the initial correction coefficient of the initial LED display screen is directly used as the target correction coefficient.
In this case, assuming that the LED display screen to be corrected is the initial LED display screen (a), the display mode of the target display screen is also as shown in fig. 4.
Step S103: splitting a first correction coefficient corresponding to the display screen blocks with changed positions and a second correction coefficient corresponding to the display screen blocks with unchanged positions from the initial correction coefficient according to the index relation; and exchanging the first correction coefficient according to the position change, and splicing the first correction coefficient and the second correction coefficient to generate a target correction coefficient.
If the target display screen block in the LED display screen to be corrected is changed in position relative to the display screen block in the initial LED display screen, the change in the position of the box body in the LED display screen to be corrected relative to the box body in the initial LED display screen is described. Assuming that the display mode of the target display screen segment in the LED display screen to be corrected is as shown in fig. 7, the display screen segments a (1,1) and a (2,1) are exchanged in position with respect to the display mode of the initial LED display screen (a) shown in fig. 4, which indicates that the LED display screen to be corrected is obtained by exchanging the positions of the boxes a1 and a5 in the initial LED display screen (a). At this time, the first correction coefficient corresponding to the display screen partition with the position variation is split from the initial correction coefficient according to the index relationship, the first correction coefficient includes two parts, which are respectively the correction coefficients corresponding to the display screen partitions a (1,1) and a (2,1), and the remaining correction coefficients are the second correction coefficients corresponding to the display screen partitions with the unchanged position. Under the condition that the box body rotates, the first correction coefficients corresponding to the split display screen blocks are directly rotated by the same angle, and then are assembled with the second correction coefficients to generate target correction coefficients.
Specifically, as shown in fig. 8, in the embodiment of the present invention, step S80: according to the index relation of the target display screen blocks, splitting and/or assembling the initial correction coefficient to generate a target correction coefficient, and the method comprises the following steps:
if the target display screen blocks of the LED display screen to be corrected completely correspond to all the display screen blocks of the at least two initial LED display screens, the LED display screen to be corrected is formed by splicing all the box bodies of the at least two initial LED display screens, then
Step S201: judging whether the position of a target display screen block in the LED display screen to be corrected and a display screen block in each initial LED display screen changes or not; if not, step S202 is executed, and if yes, step S203 is executed.
Step S202: and assembling the corresponding initial correction coefficients according to the splicing relation of the at least two initial LED display screens to generate a target correction coefficient.
If the target display screen block in the LED display screen to be corrected and the display screen block in each initial LED display screen do not have position change, it indicates that the LED display screen to be corrected is directly formed by splicing at least two initial LED display screens, and the case position interchange does not occur, and if the LED display screen to be corrected is combined by the initial LED display screen (a) and the initial LED display screen (B), the display mode of the target display screen block may be as shown in fig. 9. At the moment, the corresponding initial correction coefficients are spliced only according to the splicing relation of the initial LED display screen (A) and the initial LED display screen (B), and then the target correction coefficients can be generated.
Step S203: splitting a first correction coefficient corresponding to the display screen blocks with changed positions and a second correction coefficient corresponding to the display screen blocks with unchanged positions from the initial correction coefficient according to the index relation; and assembling the first correction coefficient and the second correction coefficient according to the splicing relation of at least two initial LED display screens to generate a target correction coefficient.
If the target display screen sub-block in the LED display screen to be corrected and the display screen sub-block in each initial LED display screen are subjected to position change, the LED display screen to be corrected is not only formed by splicing at least two initial LED display screens, but also the box body in the at least two initial LED display screens is subjected to position change. Assuming that the LED display screen to be corrected is composed of the initial LED display screen (a) and the initial LED display screen (B), as shown in fig. 10, the display screen blocks a (1,4) and B (1,1) are exchanged in position, which means that the box a4 of the initial LED display screen (a) and the box B1 of the initial LED display screen (B) are exchanged in position, at this time, the first correction coefficient corresponding to the display screen block with a position change is split from the initial correction coefficient according to the index relationship, the first correction coefficient includes two parts, which are the first correction coefficient corresponding to the display screen blocks a (1,4) and B (1,1) and the second correction coefficient corresponding to the display screen block with a position not changed, and the second correction coefficient also includes two parts, which are the corresponding display screen blocks a (1,1), a (1,2), a (1,3), a (2,1), and B, A (2,2), a (2,3), a (2,4), and a second correction coefficient corresponding to a display screen tile B (1,2), B (2,1), B (2, 2). And then the first correction coefficient and the second correction coefficient are spliced according to the splicing relation of at least two initial LED display screens to generate a target correction coefficient.
Specifically, as shown in fig. 11, in the embodiment of the present invention, step S80: according to the index relation of the target display screen blocks, splitting and/or assembling the initial correction coefficient to generate a target correction coefficient, and the method comprises the following steps:
if the target display screen block of the LED display screen to be corrected completely corresponds to a partial display screen block of an initial LED display screen, which indicates that the LED display screen to be corrected is obtained after a partial box body of the initial LED display screen is removed, then
