The time is long, and the large screen is difficult to meet the strict dark normal temperature environment in the using process.
Based on this, the present application intends to provide a solution to the above technical problem, the details of which will be explained in the following embodiments.
According to an embodiment of the application, a correction method of a tiled display device is provided.

It should be noted that, in the process of using the tiled display device, there is a display abnormal condition, and when the display abnormal condition occurs, the abnormal display module can be replaced by a standby display module prepared in advance, so as to improve the display effect of the tiled display device.
Therefore, the standby display module and each sub-display module need to be spliced to obtain the first spliced display device, and the first spliced display device is driven to be lighted up to complete the test of the standby display module.
Specifically, when testing the standby display module, the standby display module may be installed at any display module installation position of the first tiled display device, and for convenience of installation, as shown in fig. 2, the standby display module may be installed at the upper left corner of the first tiled display device.
It can be understood that under the condition that abnormal display appears in the tiled display device that puts into service, in order to avoid changing unusual display module and be equipped with for with the display module after, luminance or the unmatched phenomenon of colourity appear in standby display module and the display module on every side, before tiled display device puts into service, at the in-process that tests standby display module, obtain standby display module's reserve display parameter to the data basis is established in the correction of tiled display device behind adopting standby display module to replace unusual display module.
Optionally, in the correction method of the tiled display device provided in the embodiment of the present application, acquiring the standby display parameters of the standby display module in the first tiled display device includes: driving a first splicing display device, and acquiring first splicing display parameters of the first splicing display device; and carrying out data segmentation on the first splicing display parameters to obtain first sub-display parameters of each sub-display module and standby display parameters of the standby display module.
Specifically, after the first tiled display device is installed, the first tiled display parameters of the whole first tiled display device can be captured by the camera, and the standby display parameters of the standby display module are separated from the first tiled display parameters. And the method also can be used for carrying out one-time complete full-screen Demura correction, and capturing the first splicing display parameters of the whole first splicing display device through a camera in the Demura correction process, and separating the standby display parameters of the standby display module from the first splicing display parameters.
It should be noted that the first tiled display parameters of the first tiled display apparatus include the standby display parameters of the standby display module and the first sub-display parameters of each sub-module. Specifically, the standby display parameter and the first sub-display parameter each include a display parameter value, that is, a luminance value and a chromaticity value, and a position parameter corresponding to the display parameter value, that is, a position coordinate of the standby display module and each sub-display module in the first tiled display device.
When the first tiled display parameters of the first tiled display device are stored, the original brightness values and the original chromaticity values of the display modules can be in one-to-one correspondence with the pixel points on the first tiled display device, and the original brightness values and the original chromaticity values can be recorded and stored in a pixel coordinate (X, Y) mode.
As shown in table 1, each display module and each pixel point have a coordinate (X, Y) on the first tiled display device;
TABLE 1
| Coordinates of the object | X1 | X2 | X3 | X4 | X5 |
| Y1 | 1 | 2 | 3 | 4 | 5 |
| Y2 | 11 | 12 | 13 | 14 | 15 |
| Y3 | 21 | 22 | 23 | 24 | 25 |
| Y4 | 31 | 32 | 33 | 34 | 35 |
| Y5 | 41 | 42 | 43 | 44 | 45 |
It can be understood that the original luminance values and the chrominance values of the respective display modules are recorded and stored in the form of pixel coordinates (X, Y), specifically, the storage format of the original luminance value data is shown in table 2:
TABLE 2
| Y\ |
1 | 2 | 3 | 4 | 5 |
| 1 | A1 | A2 | A3 | A4 | A5 |
| 2 | A6 | A7 | A8 | A9 | A10 |
| 3 | A11 | A12 | A13 | A14 | A15 |
| 4 | A16 | A17 | A18 | A19 | A20 |
| 5 | A21 | A22 | A23 | A24 | A25 |
The format of the raw chromaticity value data is shown in table 3:
TABLE 3
It can be understood that after the saved first tiled display parameters are recorded in a pixel coordinate manner, the standby display parameters of the standby display module can be separated according to the position coordinates of the standby display module in the first tiled device.
For example, as shown in tables 2 and 3, if the pixel coordinate of the spare display module is (1, 1), the original luminance value of the spare display module is determined to be a1 from table 2 according to the pixel coordinate (1, 1), and the original chrominance value of the spare display module is determined to be B1 from table 3 according to the pixel coordinate (1, 1).
And step S104, splicing the sub-display modules to form a second spliced display device, and collecting second sub-display parameters of the sub-display modules in the second spliced display device.
Specifically, as shown in fig. 3, after the test of the standby display module is completed, the standby display module is replaced, and the sub-display module that is used formally is installed at the installation position of the standby display module, so as to obtain the second tiled display device.
After the second tiled display device is put into use, in order to avoid cleaning the current brightness value and the current chromatic value of each sub-display module of the whole second tiled display device when abnormal display conditions occur, the second tiled display device is placed in a strict dark normal-temperature environment for bright-chroma correction. According to the embodiment of the application, before the second tiled display device is put into use, the second sub-display parameters of each sub-display module in the second tiled display device are collected, so that a data base is laid for correction of the tiled display device after abnormal display occurs.
Optionally, in the correction method of the tiled display device provided in the embodiment of the present application, the acquiring sub-display parameters of each sub-display module in the second tiled display device includes: driving a second tiled display device, and acquiring second tiled display parameters of the second tiled display device; and carrying out data segmentation on the second splicing display parameters to obtain second sub-display parameters of each sub-display module.
Specifically, after the second tiled display device is driven to be lightened, the second tiled display parameters of the whole second tiled display device can be captured through the camera, the original brightness values and the original chromatic values of the display modules are in one-to-one correspondence with the pixel points on the second tiled display device, and the recording and the storage are carried out in a pixel coordinate mode. And separating the second sub-display parameters of each sub-display module from the second tiled display parameters based on the coordinate position of each sub-display module. The second sub-display parameters of each sub-display module can be separated in a data splitting manner, and the specific data splitting manner is not limited herein.
In addition, it should be noted that, in order to ensure the display effect of the second tiled display device after being put into use, full-screen Demura correction may be performed on the second tiled display device before being put into use, and in the Demura correction process, the second tiled display parameters of the second tiled display device may be acquired.
And S106, detecting the second tiled display device, and if display abnormity occurs, determining an abnormal display module and abnormal sub-display parameters corresponding to the abnormal display module.
It should be noted that, because the occurrence position of the abnormal display module is random, the position of the abnormal display module needs to be acquired in the process of using the second tiled display device, and a camera can be used to capture an image of the second tiled display device, so as to acquire the abnormal sub-display parameters of the abnormal display module.
Specifically, the display module with the abnormal brightness value and the abnormal chromatic value is an abnormal display module, the position coordinates corresponding to the display module with the abnormal brightness value and the abnormal chromatic value are position parameters of the abnormal display module, and the brightness value, the abnormal chromatic value and the position parameters of the abnormal display module form abnormal sub-display parameters.
Optionally, in the correction method of the tiled display device provided in the embodiment of the present application, determining the abnormal display module and the abnormal sub-display parameter corresponding to the abnormal display module includes: and comparing each second sub-display parameter with the standard parameter to obtain a comparison parameter, and if the comparison parameter is greater than a threshold value, determining the sub-display module corresponding to the second sub-display parameter as an abnormal display module. It should be noted that, the user may select the threshold according to the display requirement, and the specific value or the value range is not limited herein.
It should be noted that the abnormal display module may show that a large area of the display module is not bright, and multiple line-type abnormalities occur.
Specifically, each of the second sub-display parameters may include a luminance value and a chrominance value, and the standard parameter may include a standard luminance value and a standard chrominance value, and when detected, the luminance value is compared with the standard luminance, and if the luminance value is smaller than the threshold, it is indicated that the luminance is within the allowable range, and if the luminance value is larger than the threshold, it is indicated that the luminance is abnormal. Similarly, the colorimetric value is compared with the standard colorimetric value, if the colorimetric value is smaller than the threshold value, the colorimetric value is in an allowable range, and if the colorimetric value is larger than the threshold value, the colorimetric value is abnormal.
And S108, replacing the abnormal display module of the second spliced display device with a standby display module to form a third spliced display device.
Specifically, the position coordinates of the abnormal sub-display module in the second tiled display device are determined, the abnormal sub-display module is detached from the second tiled display device, and the standby display module is installed at the detached position, so that the process of replacing the abnormal sub-display module of the second tiled display device with the standby display module is completed, and the third tiled display device is obtained.
Step S1010, correcting the third splicing display device according to the standby display parameter, the second sub-display parameter and the abnormal sub-display parameter.
It should be noted that, because the position of the abnormal display module is random, the position of the abnormal display module is inconsistent with the installation position of the standby display module when the standby display module is tested. For example, as shown in fig. 2, when the standby display module is tested, the standby display module is installed at position 1 on the first tiled display device, and the position where the abnormal display module appears is not position 1 with a high probability, and the standby display module is used to replace the abnormal display module, so that the brightness or chromaticity of the standby display module and the surrounding display modules are not matched.
For example, as shown in fig. 4, if the position where the abnormal display module appears is position No. 2, the positions of the standby display module and the abnormal display module in the second tiled display device are different, and when the standby display module is placed at position No. 2, the phenomenon that the luminance or the chromaticity of the display modules is not matched occurs, for example, the standby display module and the display module at position No. 3 have a significant difference in luminance or chromaticity, and the uneven luminance or chromaticity can be observed significantly.
Therefore, the third spliced display device is corrected according to the standby display parameters, the second sub-display parameters and the abnormal sub-display parameters which are acquired before the second spliced display device is put into use, and the phenomenon that the standby display module and the surrounding sub-display modules are unmatched in brightness or chromaticity after the standby display module is replaced is avoided.
According to the correction method of the tiled display device, the standby display module is spliced with each sub-display module to form the first tiled display device, and standby display parameters of the standby display module in the first tiled display device are collected; splicing the sub-display modules to form a second spliced display device, and collecting second sub-display parameters of the sub-display modules in the second spliced display device; detecting the second tiled display device, and if display abnormity occurs, determining an abnormal display module and abnormal sub-display parameters corresponding to the abnormal display module; replacing the abnormal display module of the second splicing display device with a standby display module to form a third splicing display device; the third spliced display device is corrected according to the standby display parameters, the second sub-display parameters and the abnormal sub-display parameters, and the problem that in the related technology, after the abnormal display module in the display device is replaced by the standby display module, the brightness and the chromaticity of the standby display module are inconsistent with those of surrounding display modules, and the display quality of the display device is affected is solved. And then reached the effect that improves the display device's behind the change display module display quality.
In order to improve the display uniformity of the third tiled display device, optionally, in the correction method for a tiled display device provided in the embodiment of the present application, correcting the third tiled display device according to the standby display parameter, the second sub-display parameter, and the abnormal sub-display parameter includes: performing data exchange between the standby display parameters of the standby display module and the abnormal sub-display parameters corresponding to the abnormal display module; driving a third spliced display device, acquiring third sub-display parameters of each display module in the third spliced display device, and determining target display parameters based on the distribution characteristics of the third sub-display parameters of each display module; and performing display compensation on the third spliced display device according to the target display parameter so as to realize correction on the third spliced display device.
Specifically, data exchange is performed between the standby display parameters of the standby display module and the abnormal sub-display parameters corresponding to the abnormal display module, that is, brightness values and chromatic values in the standby display parameters are reserved, and the position parameters in the standby display parameters are replaced by the position parameters in the abnormal sub-display parameters.
It can be understood that, the third tiled display device is driven, because the position where the abnormal display module appears has randomness, and the position is inconsistent with the installation position of the standby display module when the standby display module is tested, the standby display module is adopted to replace the abnormal display module, and the condition that the brightness or the chromaticity of the standby display module and the surrounding display modules are not matched exists, therefore, the target display parameters need to be determined according to the third sub-display parameters of each display module in the third tiled display device, so that the display parameters of each display module are adjusted to be close to the target display parameters, and the correction of the third tiled display device is completed.
Optionally, in the correction method of the tiled display device provided in the embodiment of the present application, determining the target display parameter based on the distribution characteristic of the third sub-display parameter of each display module includes: determining a third sub-display parameter meeting a preset condition from the third sub-display parameters of each display module to obtain a plurality of third display parameters; and calculating the average value of the plurality of third display parameters to obtain the target display parameter.
It should be noted that, because the luminance value and the chromaticity value of the display module may be adjusted downward, it is difficult to adjust upward, and the luminance value and the chromaticity value of the damaged display module are relatively low, in order to ensure the reasonability of the determined target display parameters, that is, the target luminance value and the target chromaticity value, a third sub-display parameter meeting a preset condition may be determined in the third sub-display parameters of each display module, for example, the values of the acquired plurality of display parameters are sorted from low to high, the third display parameter located in the range of 20% to 90% is selected, and the target display parameter is determined based on the selected third display parameter. As another example, the top thirty percent of the data may be deleted and the target display parameters determined based on the remaining data.
Specifically, an average value of the selected third display parameter may be calculated, and the calculated average value may be determined as the target display parameter. It should be noted that, the target display parameters are not limited in the embodiments of the present application, for example, the median of the third display parameters of each display module may be taken as the target display parameters, the third display parameters of each display module may also be extracted at preset point intervals, and the target display parameters are determined according to the extracted third display parameters.
In addition, since the display parameters of different regions do not need to be kept completely consistent, for example, the brightness value and the chromaticity value of the middle region of the tiled display device are high, and the brightness value and the chromaticity value of the surrounding region are low, the brightness and the chromaticity of the tiled display device can be ensured to be uniform. Therefore, when the target display parameters are determined, the third tiled display device can be divided into a plurality of regions, and then the target display parameters are determined according to the display parameters of the display modules in each region. It should be noted that, when the target display parameters are obtained for different regions, the difference requirement of the target display parameters between the different regions needs to be met, which may be the difference range requirement or the difference change rule requirement.
It can be understood that, after the target display parameters of each display module are obtained, the difference between the original display parameter values and the target display parameter values of each display module is calculated, so as to obtain the display correction parameter values of each display module, and the display correction is performed on the third tiled display device according to the display correction parameter values, specifically, when the display correction parameters are negative numbers, the display correction parameter values are subtracted from the display parameters of the display modules, so as to obtain corrected display correction parameters, and when the display correction parameters are positive numbers, the display correction parameter values are added to the display parameters of the display modules, so as to obtain corrected display correction parameters.
For example, as shown in fig. 2 and 4, if the original brightness value of the No. 1 backup display module is 15nit (nit) and the original brightness value of the No. 2 display module is 12nit, before the second display device is put into use, the brightness correction parameter value of the No. 2 display module is-2 nit, the brightness value of the No. 2 display module after correction is 10nit, and the brightness value of the No. 3 display module is 10 nit. After the display abnormality occurs in the No. 2 display module, the No. 1 display module is installed at the position of the No. 2 display module, and the brightness value of the No. 1 display module is 15nit, and the brightness value of the No. 3 display module is 10nit, namely, the standby display module and the display modules around the abnormal display module have brightness difference.
In the embodiment of the application, the original brightness value of the No. 1 display module is placed at the No. 2 position, and the display correction parameters of each display module are recalculated. For example, the target brightness value of each display module is 10nit calculated according to the brightness value of the display module No. 1 and the brightness values of the display modules of the second display device except for the display module No. 2. Since the original brightness value of the display module No. 1 is 15nit, the target brightness value is 10nit, the brightness correction value of the display module No. 1 obtained by calculation is 5nit, and the corrected brightness value is: 15-5 ═ 10 (nit). The original brightness value of the No. 3 display module is 14nit, the target brightness value is 10nit, the brightness correction value of the No. 3 display module is 4nit, and the corrected brightness value is as follows: 14-4 is 10(nit), the brightness difference between the standby display module and the display module around the abnormal display module does not exist any more, and the matching difference between the display modules is effectively eliminated. The above expressions are merely exemplary and are not intended to be limiting.
Optionally, in the correction method of the tiled display device provided in the embodiment of the present application, the standby display parameters at least include one of the following: a standby luminance parameter, a standby chrominance parameter; the second sub-display parameter includes at least one of: a second sub-luminance parameter, a second sub-chrominance parameter; the exception sub-display parameter includes at least one of: an abnormal sub-luminance parameter, an abnormal sub-chrominance parameter; the third sub-display parameter includes at least one of: a third brightness parameter and a third chroma parameter.
Optionally, in the correction method of the tiled display device provided in the embodiment of the present application, the target display parameter at least includes one of: the target brightness parameter and the target chroma parameter, and the obtaining of the target display parameter comprises: sequencing the third brightness parameters to obtain average brightness parameters of the third brightness parameters which are greater than the preset brightness parameters so as to obtain target brightness parameters; or sorting the third chroma parameters to obtain an average chroma parameter of the third chroma parameters which is greater than the preset chroma parameters so as to obtain the target chroma parameters.
For example, 6 third luminance parameters, which are respectively 3nit, 6nit, 4nit, 1nit, 8nit and 7nit, are obtained, the preset luminance parameter is 2nit, the third luminance parameters are sorted to obtain sorting results 1nit, 3nit, 4nit, 6nit, 7nit and 8nit, the third luminance parameter greater than the preset luminance parameter 2nit is obtained, the third luminance parameter is 3nit, 4nit, 6nit, 7nit and 8nit, the average luminance parameter is 5.6nit, that is, the target luminance parameter is 5.6 nit.
It can be understood that after the third spliced display device is subjected to display correction, the third spliced display device can be driven to be lightened to determine the display effect, so that whether the third spliced display device is corrected or not is judged. Specifically, under the condition that the display uniformity meets the preset requirement, the third spliced display device is determined to finish correction, and under the condition that the display uniformity does not meet the preset requirement, the third spliced display device can be corrected in an understandable way so as to guarantee the correction effect. For example, the display effect of the third tiled display device can be observed by human eyes, and when the luminance unevenness and the chrominance unevenness are not observed, it is determined that the third tiled display device is corrected.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
