Detailed Description
In order that the above objects, features and advantages of the present application can be more clearly understood, a detailed description of the present application will be given below with reference to the accompanying drawings and detailed description. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
According to the chromatic aberration adjustment matching method, the correction coefficient is obtained according to the service time and the brightness information of the adjacent module of the replacement position module, and the correction coefficient is applied to the module after replacement to correct without secondary correction.
The color difference adjustment matching method according to the embodiments of the present application is described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a color difference adjustment matching method according to an embodiment of the present application is exemplarily shown, where the color difference adjustment matching method is applied to correction before and after a module replacement of various LED tiled display screens, and as shown in fig. 1, the color difference adjustment matching method may include the following steps:
s10: acquiring module replacement information;
when the LED display screen works, each LED box body is interacted with the control system through signals and data, and when the LED box body comprises a plurality of modules, each module on the LED box body is interacted with the control card of the LED box body through signals and data. That is, indirect signal and data interaction is generated between the module and the control system. When the module is dismounted and remounted, the module is powered off and on, and the interruption and reconnection of signals and data occur, so that the control system can identify and confirm the replacement information of the module when the module is dismounted and mounted.
S20: determining the replacement position of the module and the positions of the adjacent modules, and acquiring the service time and the brightness information of the adjacent modules;
when the module and the control system generate signals and data interruption or reconnection, the control system can determine the position of the signal, data interruption or reconnection, namely, the replacement position of the module is identified, and after the replacement position of the module is identified, the module adjacent to the replacement position can be confirmed, so that the position of the adjacent module is confirmed.
For example, an LED display screen is usually formed by splicing a plurality of LED boxes, the plurality of display modules in the plurality of LED boxes are arranged in an array, a first coordinate system can be formed according to the arrangement of the LED boxes, a second coordinate system is formed in a single LED box according to the arrangement of the display modules, when a module is replaced, the LED display screen can be firstly obtained by the LED boxes, a control card of the LED boxes obtains the position where the module is detached and installed, the control card feeds back the coordinates of the replacement position and identification information of the control card to a control system, the control system confirms the coordinates of the LED boxes according to the control card, and thus, the position of the replacement module can be accurately located by constructing two coordinate systems. After the coordinate system is established, as long as the replacement position of the module is confirmed, the position of the module adjacent to the replacement module is determined, and the control card can directly acquire the position information of the adjacent module and can convert the position information into coordinate information.
And after the position information of the adjacent module is obtained, the service time and the brightness information of the module can be obtained. In one or more embodiments, each module can separately store the usage time of the module, and a control card connected with the module can read the usage time of the module from the module through data interaction with the module. For example, after the control system obtains the information about reconnection of the module, the control system sends a signal to the control card, the control card sends a read signal to the module to request to read the service time of the module, and the module feeds back the service time of the module to the control card and then feeds back the service time to the control system through the control card. The brightness and chrominance information can be acquired in real time, and the brightness and chrominance information is included when the control card control module displays, so that the control card can directly acquire the brightness and chrominance information of the adjacent module according to the position after the position of the module is determined.
And after the control card acquires the service time and the brightness information of the adjacent modules, the service time and the brightness information are sent to a control system.
S30: determining a correction coefficient of the replaced module according to the service time and the brightness information of the adjacent modules;
after the control system receives the service time and the brightness information of the adjacent modules sent by the control card, a group of correction coefficients can be determined according to the service time and the brightness information of the adjacent modules, and the correction coefficients are used for correcting the replaced modules.
S40: and correcting the replaced module according to the correction coefficient.
After the correction coefficient is obtained, the correction coefficient can be used for correcting the replaced module, so that the corrected module is adaptive to the adjacent module in brightness and does not need to be corrected for the second time.
Referring to fig. 2, in one or more embodiments, the correction coefficients include a first correction coefficient and a second correction coefficient, the first correction coefficient is obtained according to the using time of the adjacent module, and the second correction coefficient is obtained according to the luminance information of the adjacent module, so that the step of determining the correction coefficient of the replaced module according to the using time of the adjacent module and the luminance information may include the sub-steps of:
s31: obtaining a first correction coefficient according to the service time of the adjacent module;
s33: and calculating to obtain a second correction coefficient according to the brightness and the chrominance of the adjacent module.
After the service time of the adjacent modules is obtained, a parameter of relative service time can be determined according to the service time of the adjacent modules, and the parameter is used for correcting the service time of the replaced module or correcting the brightness of the replaced module by combining the service time of the replaced module. For example, the usage time of four modules adjacent to each other in the horizontal and vertical directions of the module array may be obtained, and the first correction coefficient may be obtained according to the usage time of four adjacent modules.
The second correction coefficient is directly obtained according to the brightness of at least two adjacent modules, for example, the second correction coefficient can be obtained according to the brightness of four adjacent modules, and therefore after the second correction coefficient is used for correcting the replaced module, the brightness of the replaced module can be kept consistent with that of the adjacent module after correction, and chromatic aberration cannot be generated.
Referring to fig. 3, in some embodiments, the step of obtaining the first correction coefficient according to the usage time of the neighboring module includes:
s311: respectively determining light attenuation coefficients corresponding to the adjacent modules according to the service time of the adjacent modules;
s313: calculating the light attenuation coefficients of a plurality of adjacent modules according to a preset strategy to obtain expected light attenuation coefficients;
s315: the desired light attenuation coefficient is taken as a first correction coefficient.
For each LED lamp bead, light attenuation with different degrees can be generated along with the prolonging of the service time, and the light attenuation value is gradually increased along with the increasing of the service time, so that each lamp bead corresponds to a light attenuation function from the factory, and the light attenuation change of the lamp bead is defined. For a module, a module is generally composed of lamp beads in the same batch, and the curves of the light attenuation functions in the same batch are similar, so that one module can also define one light attenuation function, and the light attenuation function defines the change of the light attenuation value along with the increase of the service time.
After the service time of a plurality of adjacent modules is determined, a light attenuation coefficient can be respectively determined according to the light attenuation functions of the adjacent modules, and each adjacent module corresponds to one light attenuation coefficient. For example, when the usage time of four adjacent modules is used for calibration, the light attenuation coefficients corresponding to the usage time of the four adjacent modules are determined respectively. It is understood that when the light attenuation function exists and is determined, if the usage time is determined, the corresponding light attenuation value may be calculated according to the light attenuation function, and the light attenuation coefficient may be obtained according to the light attenuation value, for example, the light attenuation value of the module is directly used as the light attenuation coefficient of the module, or a ratio of the light attenuation value to an initial value at the time of shipment and/or a light attenuation value at the time of approaching the maximum lifetime is calculated, for example, the light attenuation coefficient may be defined as a current light attenuation value/(a light attenuation value at the time of maximum lifetime — an initial light attenuation value).
After the light attenuation coefficients of the adjacent modules are obtained, the expected light attenuation coefficients can be calculated according to the light attenuation coefficients of the adjacent modules. The logic of calculation may be predetermined, and may be, for example, averaging, weighted calculation, averaging after rounding off the maximum value and the minimum value, or the like.
After the expected light attenuation coefficient is determined, the expected light attenuation coefficient can be used as a first correction coefficient.
Referring to fig. 4, in other embodiments, the step of obtaining the first correction coefficient according to the usage time of the neighboring module includes:
s312: determining the maximum value and the minimum value of the service time of the adjacent modules, and calculating a difference value;
s314: judging whether the difference value is within a preset range, if so, calculating the average service time;
s316: a first correction factor is determined based on the average usage time.
When the use times of a plurality of adjacent modules are relatively close, the first correction coefficient can be determined by calculating the average use time and according to the average use time. At this time, it is necessary to first determine whether the service time of the adjacent module is within an expected range, specifically, the maximum value and the minimum value may be directly determined from the service times of the plurality of adjacent modules, and the difference between the maximum value and the minimum value may be calculated. For example, when four adjacent modules are selected, if the service times of the four adjacent modules are relatively close, the average value of the four service times may be directly calculated, and the average value may be a mathematical average value or a weighted average value.
After the average service time is obtained through calculation, the first correction coefficient can be determined according to the average service time.
In some of these embodiments, the average usage time is used as the first correction factor. In this case, in the subsequent correction, the first correction coefficient may be used in combination with the use time of the replaced module to perform the correction.
Referring to fig. 5, in other embodiments, the step of determining the first correction factor according to the average usage time includes:
s31 a: respectively determining light attenuation coefficients corresponding to the average service time of the adjacent modules according to the average service time;
s31 b: calculating according to a preset strategy and a plurality of light attenuation coefficients to obtain an average light attenuation coefficient;
s31 c: the average light attenuation coefficient is used as a first correction coefficient.
After the average service time is determined, the average service time can be substituted into the light attenuation functions of the adjacent modules according to the average service time to obtain a plurality of light attenuation coefficients, and each adjacent module corresponds to one light attenuation coefficient. The calculation of the light attenuation coefficient is the same as that in step S311. After obtaining the plurality of light attenuation coefficients, an average light attenuation coefficient may be calculated according to a preset strategy, and the average light attenuation coefficient is used as a first correction coefficient.
Referring to fig. 6, the step of calculating the second correction coefficient according to the brightness of the adjacent module includes:
s331: and calculating to obtain average brightness according to the brightness of the adjacent modules to obtain a second correction coefficient.
After the brightness values of the plurality of adjacent modules are obtained, in order to make the replaced module adapt to the display of the adjacent module after the correction, the average brightness value can be calculated, and the average brightness value is used for the correction of the replaced module.
Referring to FIG. 7, in one or more embodiments, the step of calibrating the replaced module according to the calibration factor includes
S41: acquiring the service time of the replaced module;
s43: determining a compensation value according to the service time of the replaced module and the first correction coefficient;
s45: and determining a final brightness correction value according to the compensation value by taking the second correction coefficient as a target value, and using the final brightness correction value for correcting the replaced module.
After the first correction coefficient and the second correction coefficient are obtained, the first correction coefficient and the second correction coefficient can be used for correcting the replaced module. When the correction is carried out, the service time of the replaced module is firstly obtained, so that the service time is stored in the replaced module, and when the replaced module is installed on the LED box body, the replaced module is communicated with the control card of the LED box body, and the service time of the replaced module can be read by the control card.
And after the service time of the replaced module is obtained, determining the light attenuation value of the replaced module, and defining the light attenuation value of the replaced module as an actual light attenuation value. When the first correction coefficient is the light attenuation value, if the actual light attenuation value is equal to the first correction coefficient, the module does not need to be corrected after replacement. If the actual light attenuation value is not equal to the first correction coefficient, determining a compensation value according to the difference value of the actual light attenuation value and the first correction coefficient for correcting the brightness. When the first correction coefficient is the ratio, an expected optical attenuation value can be calculated according to the optical attenuation value during the maximum service life of the replaced module, the initial optical attenuation value and the ratio, and the expected optical attenuation value is compared with the actual optical attenuation value to determine a compensation value. And when the first correction coefficient is the service time, substituting the first correction coefficient into the light attenuation function of the replaced module to obtain a substitute light attenuation value, and comparing the substitute light attenuation value with an expected light attenuation value to determine a compensation value.
After the compensation value is determined, the average brightness degree can be used as the expected brightness degree to be corrected, a final brightness degree correction matrix is determined according to the compensation value, the final brightness degree correction matrix is used for correcting the replaced module, and the brightness degree of the module can be corrected to be the average brightness degree, so that the replaced module is in accordance with the display of the adjacent module after being corrected, and color difference cannot be generated. For example, the compensation value and the factory calibration coefficient of the replaced module can be used to obtain a final brightness calibration matrix, or the compensation value and the real-time collected brightness value of the replaced module can be used to obtain the final brightness calibration matrix.
According to the chromatic aberration adjustment matching method, the correction coefficient is obtained according to the service time and the brightness information of the adjacent module of the replacement position module, the correction coefficient is applied to the module after replacement for correction, the module after replacement conforms to the brightness of the adjacent module after correction, chromatic aberration cannot be generated, and secondary correction is not needed.
