[0020] The LED display calibration method provided in this application embodiment can be applied to LED display calibration scenarios. Specifically, taking the replacement of LED modules in an LED display as an example, due to differences in production batches and manufacturing processes of the replaced LED display modules, the display effect of the replaced LED display modules will differ from that of other display modules in the LED display. Therefore, it is necessary to calibrate the replaced LED display modules to ensure uniform display effect of the LED display.

[0021] In the process of developing this invention, the inventors discovered that in the prior art, control software calibrates the display data of each LED in the LED module, sends the calibrated display data to a receiving card, and the receiving card drives the LEDs to display based on the calibrated display data. Because the receiving card needs to receive the corresponding calibrated display data for each LED, the amount of data received is large, the data transmission time is long, and the calibration efficiency is low.

[0022] Therefore, this application only receives the regional adjustment coefficient and corrects the first display data of the LED beads in the area to be corrected based on the regional adjustment coefficient. Compared with the prior art, it does not need to receive the corrected data of each LED bead in the area to be corrected, the amount of data received is small, and the correction efficiency is improved.

[0023] Please see Figure 1 This is a flowchart illustrating an LED display screen calibration method provided in one embodiment of this application. This application provides an LED display screen calibration method, including the following steps: S10: Receive calibration command; the calibration command includes the position information of the area to be calibrated in the LED display screen and the area adjustment coefficient; S20: Based on the location information, obtain the first display data of the LED beads in the area to be calibrated; calibrate the first display data according to the area adjustment coefficient to obtain the second display data; send the second display data to the LED beads so that the LED beads display according to the second display data.

[0024] By applying the embodiments of this application, a calibration command is received; the calibration command includes the position information of the area to be calibrated in the LED display screen and the area adjustment coefficient; based on the position information, first display data of the LED beads in the area to be calibrated is obtained; based on the area adjustment coefficient, the first display data is calibrated to obtain second display data; the second display data is sent to the LED beads so that the LED beads display according to the second display data. This application only needs to receive the position information and the area adjustment coefficient, and calibrate the first display data of the LED beads in the area to be calibrated according to the area adjustment coefficient. Compared with the prior art, it does not need to receive the calibrated data of each LED bead in the area to be calibrated, the amount of data received is small, and the calibration efficiency is improved.

[0025] The following embodiments of this application use a receiving card as the execution subject to illustrate the various steps of the LED display calibration method.

[0026] For step S10, a calibration instruction is received; the calibration instruction includes the position information of the area to be calibrated in the LED display screen and the area adjustment coefficient.

[0027] The area to be calibrated is the region where display data correction is required. The display effect of this area differs from that of other areas in the LED display screen. Specifically, the area to be calibrated can be an area after replacing the LED module, or an area where the LED module is malfunctioning or malfunctioning.

[0028] The location information includes the position coordinates of each LED in the area to be calibrated. The area adjustment coefficient is used to correct the display data of each LED in the area to be calibrated; each area to be calibrated corresponds to one area adjustment coefficient.

[0029] In this embodiment, the receiving card receives a calibration command sent by a control terminal. The control terminal includes, but is not limited to, a host computer, a personal computer, a tablet computer, and a mobile client. The control terminal has an interactive interface, where users can select the area to be calibrated and input the area adjustment coefficient. In response to the user's operation, the control terminal generates a calibration command and sends the calibration command to the receiving card.

[0030] For step S20, based on the location information, the first display data of the LED beads in the area to be calibrated is obtained; based on the area adjustment coefficient, the first display data is calibrated to obtain the second display data; the second display data is sent to the LED beads so that the LED beads display according to the second display data.

[0031] The first display data is the raw display data, including but not limited to raw brightness display data and raw chromaticity display data.

[0032] In this embodiment, the receiving card obtains the first display data of each LED bead based on its position coordinates within the area to be calibrated. The area adjustment coefficient and the first display data of each LED bead are input into a preset calibration formula to obtain the second display data of each LED bead. The receiving card then sends the second display data of each LED bead to the corresponding LED bead, which displays the second display data.

[0033] In one embodiment, step S20, which involves correcting the first display data according to an adjustment coefficient to obtain the second display data, includes step S201, as follows: S201: Multiply the first display data by the adjustment coefficient to obtain the second display data.

[0034] In this embodiment of the application, the first display data of each LED bead in the area to be calibrated is multiplied by the adjustment coefficient to obtain the second display data of each LED bead.

[0035] In this embodiment of the application, by multiplying the first display data by the adjustment coefficient, the second display data can be automatically obtained, thereby realizing the correction of the display data of the area to be corrected.

[0036] In one embodiment, after step S20, steps S21 to S22 are included, as follows: S21: When the display effect of the area to be calibrated is inconsistent with the display effect of the non-calibrated area, receive the updated calibration command; wherein, the updated calibration command includes the updated area adjustment coefficient; the non-calibrated area is the area in the LED display screen other than the area to be calibrated.

[0037] The display effects include, but are not limited to, brightness display effects and color display effects.

[0038] The non-calibrated area can be the surrounding area of ​​the calibrated area, and the LED modules in the surrounding area are adjacent to the LED modules in the calibrated area.

[0039] In this embodiment, when the display effect of the area to be calibrated observed by the human eye is inconsistent with the display effect of the non-calibrated area, or when the measured display effect of the area to be calibrated is inconsistent with the display effect of the non-calibrated area, the user can input a new area adjustment coefficient at the control terminal. The control terminal responds to the user's operation, generates an updated calibration command, and sends the updated calibration command to the receiving card. The receiving card receives the updated calibration command.

[0040] S22: Adjust the display effect of the area to be corrected according to the updated area adjustment coefficient until the display effect of the area to be corrected is consistent with the display effect of the non-area to be corrected.

[0041] In this embodiment, the receiving card recalibrates the first display data according to the updated area adjustment coefficient to obtain calibrated display data, and sends the calibrated display data to the LED beads, which then display the calibrated display data. If the display effect of the area to be calibrated is still inconsistent with the display effect of the non-calibrated area, step S21 and the step of adjusting the display effect of the area to be calibrated according to the updated area adjustment coefficient are repeated until the display effect of the area to be calibrated is consistent with the display effect of the non-calibrated area.

[0042] This application embodiment can achieve the same display effect between the area to be corrected and the area not to be corrected by receiving the updated area adjustment coefficient.

[0043] In one embodiment, after step S21, steps S211 to S213 are included, as follows: S211: Measure the first display parameter value corresponding to the display effect of the area to be calibrated and the second display parameter value corresponding to the display effect of the non-calibrated area using a colorimeter.

[0044] Among them, the colorimeter is used to measure luminance, color temperature, and color coordinates.

[0045] The display parameter values ​​are used to quantitatively describe the display effect of the LED module. These display parameter values ​​include, but are not limited to, brightness values, color temperature values, and color coordinates.

[0046] In this embodiment, a colorimeter is used to measure the first display parameter value corresponding to the display effect of the area to be calibrated and the second display parameter value corresponding to the display effect of the non-calibrated area.

[0047] S212: When the difference between the first display parameter value and the second display parameter value is within a preset range, it is determined that the display effect of the area to be corrected is consistent with the display effect of the area not to be corrected.

[0048] The preset range can be manually set according to actual needs.

[0049] In this embodiment of the application, the difference between the first display parameter value and the second display parameter value is calculated, and it is determined whether the difference is within a preset range. When the difference is within the preset range, it means that the display effect of the area to be corrected is consistent with the display effect of the area not to be corrected.

[0050] S213: When the difference between the first display parameter value and the second display parameter value is not within the preset range, it is determined that the display effect of the area to be corrected is inconsistent with the display effect of the area not to be corrected.

[0051] In this embodiment of the application, when the difference is not within a preset range, it indicates that the display effect of the area to be corrected is inconsistent with the display effect of the area not to be corrected.

[0052] This application embodiment can automatically and quickly determine whether the display effect of the area to be corrected is consistent with the display effect of the non-area to be corrected by measuring the first display parameter value and the second display parameter value.

[0053] In one embodiment, after step S22, steps S221 to S223 are included, as follows: S221: Obtain the third display data of the area to be corrected; wherein the data type of the third display data is different from that of the first display data.

[0054] The third type of display data includes, but is not limited to, thermal data and gap data. Thermal data refers to data related to the light emission and heat dissipation of LED beads, while gap data refers to data related to the inconsistent brightness of the LED display screen caused by inconsistent gaps between LED modules during the installation of LED beads.

[0055] In this embodiment of the application, the receiving card can obtain the third display data of the area to be corrected from its own memory.

[0056] S222: Obtain target display data based on the target area adjustment coefficient, the first display data, and the third display data; wherein, the target area adjustment coefficient is the area adjustment coefficient of the area to be corrected when the display effect of the area to be corrected is consistent with the display effect of the non-area to be corrected.

[0057] In this embodiment of the application, the target area adjustment coefficient, the first display data, and the third display data are multiplied together to obtain the target display data.

[0058] S223: Control the LED beads to display the corresponding display effect based on the target display data.

[0059] In this embodiment, when the first display data is brightness display data and chromaticity display data, and the third display data is thermal data, the display effect is a superposition of brightness display effect, chromaticity display effect, and thermal display effect. When the first display data is brightness display data and chromaticity display data, and the third display data is thermal data and gap data, the display effect is a superposition of brightness display effect, chromaticity display effect, thermal display effect, and gap display effect.

[0060] After obtaining the target area adjustment coefficient, the present application embodiment can use the target area adjustment coefficient to correct the third display data in the area to be corrected, which has a different data type than the first display data. This enables the correction of multiple different types of display data. Compared with the prior art, which corrects each type of display data separately, the correction efficiency is high.

[0061] In one embodiment, after step S222, step S2221 is included, as follows: S2221: Store the target display data in the storage space of an external device.

[0062] External devices are devices that are different from receiving cards and control terminals.

[0063] In this embodiment, the receiving card stores the target display data in the storage space of an external device. When the receiving card malfunctions, the target display data can be read from the external device, thus avoiding data loss caused by the receiving card malfunction.
