Description

Technical Field

[0002] In some technologies, when correcting the brightness of an LED display screen, the brightness data of each LED lamp bead in the LED display screen is usually collected by a dedicated brightness acquisition device, and then a brightness coefficient is added to each LED lamp bead through an algorithm, so that all LED lamp beads can present a relatively uniform brightness effect.

[0003] However, since the LED display screen is composed of splicing display units, if one or more display units of the LED display screen need to be replaced, or if it needs to be re-spliced into an LED display screen on-site during the leasing process, at this time, bright and dark lines will appear at the splicing joints of the re-spliced display units. At this time, if the LED display screen is corrected again, it is time-consuming and laborious.

[0004] In some technologies, when bright and dark lines appear at the splicing joints of the re-spliced display units, the correction software of the LED display screen is used to display a solid color, so that the content displayed by the LED display screen and the correction software are synchronized point-to-point. The edges of the display units with differences are found by human eye observation, and then the parameters of this edge are adjusted on the correction software. The solid color displayed on the correction software will change the color of the corresponding position according to the modified parameters. Finally, observe the LED display screen again. If no difference is found, the correction is completed.

[0005] In the process of implementing the present invention, the inventors found that at least the following problems exist in the above technologies: The method of correcting by observing and adjusting the differences by human eye requires continuously observing the display effect of the LED display screen and adjusting the coefficients of the edges of the display units.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

The character " / " generally represents an "or" relationship between the associated objects before and after.

[0041] To better understand the design solution of the present application, the correction methods of LED displays in some technologies will be described below.

[0042] When one or more display units of an LED display need to be replaced, or when it is necessary to splice them on-site into an LED display during the rental process, bright and dark lines will appear at the splicing points of the re-spliced display units. In some technologies, the correction of LED displays mainly includes two methods. The first method is to add 4 parameters to each display unit through the controller in the LED display. First, display a solid color on the calibration software to make the display content of the LED display and the calibration software synchronize point-to-point. Observe with the human eye and find the edges of the display units with differences. Adjust the parameters of this edge on the calibration software. The solid color displayed on the calibration software will change the color of the corresponding position according to the modified parameters. Observe the display screen. If no differences are found, this correction is completed. The second method is to directly change the overall calibration data to achieve the correction effect. Manually modify the calibration data of the corresponding positions of the entire display unit with the human eye, and then send it to the display screen as a whole to observe the effect.

[0043] In the process of implementing the present invention, the inventor found that there are at least the following problems in the above technologies: The first method of correction by observing and adjusting differences with the human eye requires continuously observing the display effect of the LED display and adjusting the coefficients of the edges of the display units. The efficiency is low, the labor cost is high, and it is easily affected by the subjective experience of the human eye, resulting in low correction accuracy. The second method has a large amount of data sent, a slow speed, and the effect is difficult to be immediately reflected on the LED display, increasing the difficulty of correction.

[0044] Therefore, the embodiment of this application proposes a method for correcting the splicing brightness of an LED display.

[0045] The method for correcting the splicing brightness of an LED display provided in the embodiment of this application can be executed by an LED display splicing brightness correction device. The LED display splicing brightness correction device can be implemented in software and / or hardware. The LED display splicing brightness correction device can be composed of two or more physical entities, or can be composed of one physical entity. For example, the LED display splicing brightness correction device can be an intelligent device such as a computer, a mobile phone, a tablet or an interactive tablet. Specifically, the ED display splicing brightness correction device can be any electronic device with an LED display, such as an LED all-in-one machine, an LED engineering screen, etc., such as the LED display used in a large conference and the LED display used on a stage.

[0046] The LED display splicing brightness correction device may include one or more processing cores, which can implement the LED display splicing brightness correction method of the present application in a purely software manner, or can also adopt a combination of software and hardware to implement the LED display splicing brightness correction method of the present application. For example, at least one of the hardware forms of digital signal processing, field programmable gate array, and programmable logic array can be used to implement it; it can integrate one or a combination of a central processing unit, an image processor, a modem, etc. The LED display splicing brightness correction device can run an application program for the LED display splicing brightness correction method, and the application program can be presented in a form adapted to the interactive flat panel. For example, it can be an APP application program. In some examples, it can also be presented in forms such as system plugins and web plugins.

[0047] Example 1

[0048] The following will combine Figures 1 to 3 , and make a further detailed description of the LED display splicing brightness correction method of the present application.

[0049] Please refer to Figure 1 , a LED display splicing brightness correction method provided by an embodiment of the present application includes the following steps:

[0050] Step S110: After the LED display is spliced, in response to a trigger operation for splicing brightness correction, obtain first correction data of each LED bead in the LED display and the position of each LED bead in the LED display; wherein, the LED display includes a plurality of spliced LED beads; the first correction data is the brightness correction coefficient after the LED bead is corrected during the production of the LED bead.

[0051] An LED display is a flat panel display composed of small LED beads, which is a device for displaying various information such as text, images, and videos; specifically, the LED display is formed by splicing a plurality of LED display units, and the plurality of LED display units are spliced by LED lamp boards, and the LED lamp boards include a plurality of LED beads.

[0052] After the LED display screen is assembled, it includes at least one of the following situations: after the display units are assembled into an LED display screen after being shipped from the factory; or, after replacing one or more display units and reassembling them into an LED display screen. Specifically, for example, when replacing the layout of the LED display screen in stage applications or changing the location of the LED display screen in the rental industry, it is necessary to disassemble and reassemble the LED display screen. In addition, when one or more display units in the LED display screen are damaged and need to be repaired by replacing spare parts, it is also necessary to disassemble and reassemble the LED display screen. After the display units are assembled into an LED display screen after being shipped from the factory; or, after replacing one or more display units and reassembling them into an LED display screen, automatic correction can be performed. The trigger operation in response to the splicing brightness correction can be to click the calibration software of the LED display screen to obtain the first calibration data of each LED lamp bead in the LED display screen and the position of each LED lamp bead in the LED display screen.

[0053] When manufacturing the LED lamp beads, the factory will perform brightness calibration on each LED lamp bead to eliminate the brightness differences among all the LED lamp beads in the display unit and make the brightness of all the LED lamp beads in the display unit consistent.

[0054] Step S120: According to the position of the LED lamp bead in the LED display screen and the mapping relationship between the preset position and the compensation coefficient table, obtain the target compensation coefficient of the LED lamp bead.

[0055] Among them, a compensation coefficient table corresponding one-to-one to the display screen of the LED display screen is stored in the LED display screen splicing brightness correction device. The compensation coefficient table is obtained through the following process: Since the LED display screen is composed of multiple display units spliced together; the display unit is composed of multiple LED lamp boards spliced together; the LED lamp board includes multiple LED lamp beads. Therefore, after the LED lamp beads are spliced into an LED display screen, the brightness values of all the LED lamp beads are collected, the compensation coefficients of all the LED lamp beads are calculated through the calibration software, the brightness values of the LED lamp beads are corrected through the compensation coefficients to make the brightness values of the LED lamp beads tend to be consistent, and the compensation coefficients and the positions of the LED lamp beads are recorded. Then, replace different types of LED lamp boards and adjust the positions of the LED lamp boards, and repeat the above operations multiple times to obtain the compensation coefficients corresponding to the LED lamp beads at each position, so as to obtain the compensation coefficient table. Furthermore, according to the position of the LED lamp beads in the display screen of the LED display screen, look up the compensation coefficient corresponding to the same position in the compensation coefficient table to obtain the target compensation coefficient of the LED lamp bead.

[0056] Step S130: Obtain the second calibration data of the LED lamp bead according to the first calibration data and the target compensation coefficient.

[0057] The second correction coefficient is the working correction coefficient of the LED lamp beads, and the LED lamp beads work according to the working correction coefficient to emit corresponding brightness.

[0058] Step S140: Correct the splicing brightness of the LED display screen according to the second correction data.

[0059] In the embodiment of the present application, after splicing the LED display screen, in response to the trigger operation of splicing brightness correction, the first correction data of each LED lamp bead in the LED display screen and the position of each LED lamp bead in the LED display screen are obtained. The LED display screen includes a plurality of spliced LED lamp beads. The first correction data is the brightness correction coefficient after correcting the LED lamp beads during the production of the LED lamp beads. According to the position of the LED lamp beads in the LED display screen and the mapping relationship between the preset position and the compensation coefficient table, the target compensation coefficient of the LED lamp beads is obtained. According to the first correction data and the target compensation coefficient, the second correction data of the LED lamp beads is obtained. According to the second correction data, the splicing brightness of the LED display screen is automatically corrected. On-site correction does not require spending a lot of time on trial correction. When reinstalling and replacing spare parts, there is no need to send professional personnel to the site for correction or seam repair, which improves the correction accuracy and efficiency and reduces the labor cost.

[0060] Please refer to Figure 2 , in an embodiment of the present application, the method for correcting the splicing brightness of the LED display screen further includes steps S100 to S101:

[0061] Step S100: When producing the LED lamp beads, obtain the brightness parameter of the LED lamp beads, and adjust the brightness parameter to the brightness target value to adjust the brightness of the LED lamp beads to the target effect.

[0062] When producing the display unit, since there are certain fluctuations in the brightness display between the LED lamp beads inside the display unit, it is necessary to perform brightness correction on the LED lamp beads inside the display unit to make the brightness of the LED lamp beads inside the display unit consistent. In the embodiment of the present application, when producing the LED lamp beads, the brightness parameter of the LED lamp beads is obtained. The brightness parameter is the brightness value of the LED lamp beads. The brightness parameter is adjusted to the brightness target value to adjust the brightness of the LED lamp beads to the target effect. The target effect is that the brightness of the LED lamp beads is consistent with the brightness of other LED lamp beads in the display unit.

[0063] Step S101: Divide the brightness target value by the brightness parameter to obtain the first correction data of the LED lamp beads.

[0064] In the embodiment of the present application, divide the brightness target value by the brightness parameter, that is, use the ratio of the brightness target value to the brightness parameter as the first correction data of the LED lamp bead.

[0065] In the embodiment of the present application, by obtaining the brightness parameter of the LED lamp bead, adjusting the brightness parameter to the brightness target value, dividing the brightness target value by the brightness parameter to obtain the first correction data of the LED lamp bead, and further adjusting the compensation coefficient for the first correction data, the correction accuracy of the LED lamp bead can be improved.

[0066] Please refer to Figure 3 , in an embodiment of the present application, obtaining the position of the LED lamp bead in the LED display screen in step S110 includes steps S111 to S113:

[0067] Step S111: Obtain the first port identifier connected to each display unit in the LED display screen, the second port identifier of the LED lamp board, and the model of each LED lamp board in the display unit.

[0068] The LED display screen is composed of multiple display units spliced together. Each display unit includes an output port and an input port. The output port of the previous display unit is connected to the input port of the next display unit. The first port identifier is used to identify the position information connected to each display unit. The display unit is composed of multiple LED lamp boards spliced together. Each LED lamp board includes an output port and an input port. The output port of the previous LED lamp board is connected to the input port of the next LED lamp board. The second port identifier is used to identify the position information connected to each LED lamp board. The LED lamp board includes multiple LED lamp beads. Since each LED lamp board has its own model, the position information of each LED lamp bead in the LED lamp board can be obtained through the model.

[0069] Step S112: Determine the first position of each display unit in the LED display screen according to the first port identifier, determine the second position of the LED lamp board in the display unit according to the second port identifier, and determine the third position of the LED lamp bead in the LED lamp board according to the model.

[0070] In the embodiments of the present application, during the splicing process, each display unit has an output port serial number, which is, for example, an Ethernet port serial number, to identify the first position of the display unit in the entire LED display screen. The display unit is formed by splicing multiple LED lamp boards, and each LED lamp board also has an output port serial number to identify the second position of the LED lamp board in the entire display unit. Each LED lamp board has its own model number to identify the third position of each LED lamp bead in the entire LED lamp board.

[0071] Step S113: Determine the position of the LED lamp bead in the LED display screen according to the first position, the second position, and the third position.

[0072] In the embodiments of the present application, by obtaining the first port identifier of the display unit, the second port identifier of the LED lamp board, and the model number of the LED lamp board, the position of each LED lamp bead can be automatically and quickly determined.

[0073] In an embodiment of the present application, the values of the target compensation coefficients in the compensation coefficient table in step S120 change in an increasing or decreasing manner in multiple consecutive rows and columns. In the embodiments of the present application, the values of the target compensation coefficients in the compensation coefficient table present a certain gradual change rule. Specifically, at the splicing point between a display unit and an adjacent display unit, due to the light compensation of a relatively large number of LED lamp beads around, the brightness of the outermost edge LED lamp beads is greater than that of the LED lamp beads inside the edge. Therefore, the compensation coefficient of the outermost edge LED lamp beads is the largest; and in the process from the outermost to the inside, since the number of LED lamp beads of the adjacent display units around decreases, the light compensation weakens. Therefore, the compensation coefficients of the LED lamp beads in multiple rows and columns decrease. By making the coefficient change of the LED lamp beads in multiple consecutive rows and columns at the edge of the display unit in an increasing or decreasing manner, the brightness fusion between the LED lamp beads during the splicing of the LED display screen is smoother and softer.

[0074] In an exemplary embodiment of the present application, step S130 of obtaining the second correction data of the LED lamp bead according to the first correction data and the target compensation coefficient includes step S131:

[0075] Step S131: Use the product of the first correction data and the target compensation coefficient as the second correction data of the LED lamp bead. By multiplying the first correction data by the target compensation coefficient to obtain the second correction data of the LED lamp bead, the LED corrected according to the second correction data can quickly reach the target brightness.
