[0025] The LED display screen calibration method provided in the embodiment of the present application can be applied to the calibration scenario of the LED display screen. Specifically, taking the replacement of LED modules in the LED display screen as an example, since the production batch and manufacturing process of the replaced LED display module are different, the display effect of the replaced LED display module and other display modules of the LED display screen will be different. Therefore, it is necessary to calibrate the replaced LED display module to make the display effect of the LED display screen uniform.

[0026] The inventor discovered in the process of implementing the present invention that in the prior art, the control software corrects the display data of each LED lamp bead of the LED module, and sends the corrected display data to the receiving card, and the receiving card drives the LED lamp bead to display according to the corrected display data. Since the receiving card needs to receive the corrected display data corresponding to each LED lamp bead, the amount of data received is large, the data transmission time is long, and the correction efficiency is low.

[0027] To this end, the present application only receives the regional adjustment coefficient and corrects the first display data of the LED lamp beads in the area to be corrected according to the regional adjustment coefficient. Compared with the prior art, there is no need to receive the corrected data of each LED lamp bead in the area to be corrected. The amount of data received is small, thereby improving the correction efficiency.

[0028] See also Figure 1 , which is a flow chart of a LED display screen calibration method provided by an embodiment of the present application. The present application embodiment provides a LED display screen calibration method, comprising the following steps:

[0029] S10: receiving a correction instruction; the correction instruction includes the position information of the area to be corrected in the LED display screen and the area adjustment coefficient;

[0030] S20: Acquire first display data of the LED lamp beads in the area to be corrected according to the position information; correct the first display data according to the area adjustment coefficient to obtain second display data; send the second display data to the LED lamp beads so that the LED lamp beads display according to the second display data.

[0031] The embodiment of the present application is applied, by receiving a correction instruction; the correction instruction includes the position information of the area to be corrected in the LED display screen and the area adjustment coefficient; according to the position information, the first display data of the LED lamp beads in the area to be corrected is obtained; according to the area adjustment coefficient, the first display data is corrected to obtain the second display data; the second display data is sent to the LED lamp beads, so that the LED lamp beads display according to the second display data. The present application only needs to receive the position information and the area adjustment coefficient, and according to the area adjustment coefficient, the first display data of the LED lamp beads in the area to be corrected is corrected. Compared with the prior art, there is no need to receive the corrected data of each LED lamp bead in the area to be corrected, the amount of data received is small, and the correction efficiency is improved.

[0032] The following embodiments of the present application use a receiving card as the execution body to illustrate the various steps of the LED display screen calibration method.

[0033] For step S10, a correction instruction is received; the correction instruction includes position information of the area to be corrected in the LED display screen and the area adjustment coefficient.

[0034] The area to be corrected is an area where display data correction is required. The display effect of this area is different from the display effects of other areas in the LED display screen. Specifically, the area to be corrected can be an area after the LED module is replaced, or an area where the LED module displays a fault or abnormality.

[0035] The position information includes the position coordinates of each LED lamp bead in the area to be corrected. The area adjustment coefficient is used to correct the display data of each LED lamp bead in the area to be corrected, and each area to be corrected corresponds to a area adjustment coefficient.

[0036] In the embodiment of the present application, the receiving card receives the correction instruction sent by the control end. The control end includes but is not limited to a host computer, a personal computer, a tablet computer and a mobile client. The control end is provided with an interactive interface, and the user can select the area to be corrected and input the area adjustment coefficient on the interactive interface. The control end generates a correction instruction in response to the user's operation and sends the correction instruction to the receiving card.

[0037] For step S20, the first display data of the LED lamp beads in the area to be corrected is obtained according to the position information; the first display data is corrected according to the area adjustment coefficient to obtain the second display data; the second display data is sent to the LED lamp beads so that the LED lamp beads display according to the second display data.

[0038] The first display data is original display data, including but not limited to original brightness display data and original chromaticity display data.

[0039] In the embodiment of the present application, the receiving card obtains the first display data of each LED lamp bead according to the position coordinates of each LED lamp bead in the area to be corrected. The regional adjustment coefficient and the first display data of each LED lamp bead are input into a preset correction formula to obtain the second display data of each LED lamp bead. The receiving card sends the second display data of each LED lamp bead to the corresponding LED lamp bead, and the LED lamp bead displays the second display data.

[0040] In one embodiment, the step of correcting the first display data according to the adjustment coefficient to obtain the second display data in step S20 includes step S201, which is specifically as follows:

[0041] S201: multiplying the first display data by the adjustment coefficient to obtain second display data.

[0042] In the embodiment of the present application, the first display data of each LED lamp bead in the area to be corrected is multiplied by the adjustment coefficient to obtain the second display data of each LED lamp bead.

[0043] In the embodiment of the present application, the second display data can be automatically obtained by multiplying the first display data by the adjustment coefficient, thereby realizing correction of the display data of the area to be corrected.

[0044] In one embodiment, after step S20, steps S21 to S22 are included, which are specifically as follows:

[0045] S21: When the display effect of the area to be corrected is inconsistent with the display effect of the area not to be corrected, receiving an updated correction instruction; wherein the updated correction instruction includes an updated regional adjustment coefficient; the area not to be corrected is the area in the LED display screen except the area to be corrected.

[0046] The display effect includes but is not limited to brightness display effect and chromaticity display effect.

[0047] The non-to-be-corrected area may be a peripheral area of ​​the to-be-corrected area, and the LED modules in the peripheral area are adjacent to the LED modules in the to-be-corrected area.

[0048] In an embodiment of the present application, when the display effect of the area to be corrected observed by the human eye is inconsistent with the display effect of the area not to be corrected, or the display effect of the area to be corrected measured is inconsistent with the display effect of the area not to be corrected, the user can input a new area adjustment coefficient at the control end, and the control end generates an updated correction instruction in response to the user's operation, and sends the updated correction instruction to the receiving card, and the receiving card receives the updated correction instruction.

[0049] S22: adjusting 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 area not to be corrected.

[0050] In the embodiment of the present application, the receiving card recalibrates the first display data according to the updated regional adjustment coefficient, obtains the corrected display data, sends the corrected display data to the LED lamp beads, and the LED lamp beads display the corrected display data. When the display effect of the area to be corrected is still inconsistent with the display effect of the area not to be corrected, repeat step S21 and the step of adjusting the display effect of the area to be corrected according to the updated regional adjustment coefficient until the display effect of the area to be corrected is consistent with the display effect of the area not to be corrected.

[0051] The embodiment of the present application can achieve consistency between the display effect of the area to be corrected and the display effect of the area not to be corrected by receiving the updated area adjustment coefficient.

[0052] In one embodiment, after step S21, steps S211 to S213 are included, which are specifically as follows:

[0053] S211: measuring, by a colorimeter, a first display parameter value corresponding to the display effect of the area to be corrected and a second display parameter value corresponding to the display effect of the area not to be corrected.

[0054] Among them, the colorimeter is used to measure brightness value, color temperature value and color coordinates.

[0055] The display parameter values ​​are used to quantitatively describe the display effect of the LED module, including but not limited to brightness value, color temperature value and color coordinates.

[0056] In the embodiment of the present application, a first display parameter value corresponding to the display effect of the area to be corrected and a second display parameter value corresponding to the display effect of the area not to be corrected are measured by a colorimeter.

[0057] S212: When the difference between the first display parameter value and the second display parameter value is within a preset range, determining that the display effect of the area to be corrected is consistent with the display effect of the area not to be corrected.

[0058] Among them, the preset range can be set manually according to actual needs.

[0059] In an embodiment of the present application, the difference between the first display parameter value and the second display parameter value is calculated to determine whether the difference is within a preset range. When the difference is within the preset range, it indicates that the display effect of the area to be corrected is consistent with the display effect of the area not to be corrected.

[0060] S213: When the difference between the first display parameter value and the second display parameter value is not within a preset range, determining that the display effect of the to-be-corrected area is inconsistent with the display effect of the non-to-be-corrected area.

[0061] In the embodiment of the present application, when the difference is not within the 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.

[0062] The embodiment of the present application can automatically and quickly determine whether the display effect of the area to be corrected is consistent with the display effect of the area not to be corrected by measuring the first display parameter value and the second display parameter value.

[0063] In one embodiment, after step S22, steps S221 to S223 are included, which are specifically as follows:

[0064] S221: Acquire 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.

[0065] The third 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 lamp beads, and gap data refers to data related to the inconsistent brightness of the LED display screen caused by the inconsistent gaps between LED modules during the installation of LED lamp beads.

[0066] In the embodiment of the present application, the receiving card can obtain the third display data of the area to be corrected from its own memory.

[0067] S222: Obtain target display data according to 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 area not to be corrected.

[0068] In the embodiment of the present application, the target area adjustment coefficient, the first display data, and the third display data are multiplied to obtain the target display data.

[0069] S223: According to the target display data, the LED lamp beads are controlled to display the corresponding display effect.

[0070] In the embodiment of the present application, 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 the 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 the superposition of brightness display effect, chromaticity display effect, thermal display effect and gap display effect.

[0071] After obtaining the target adjustment coefficient, the embodiment of the present application can use the target adjustment coefficient to correct the third display data in the area to be corrected whose data type is different from the first display data, thereby realizing correction of multiple different types of display data. Compared with the prior art of separately correcting each type of display data, the correction efficiency is high.

[0072] In one embodiment, after step S222, step S2221 is included, which is specifically as follows:

[0073] S2221: Store the target display data into the storage space of the external device.

[0074] The external device is a device different from the receiving card and the control terminal.

[0075] In the embodiment of the present application, the receiving card stores the target display data in the storage space of the external device. When an abnormality occurs in the receiving card, the target display data can be read from the external device, thereby avoiding data loss caused by an abnormality of the receiving card.
