[0048] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art based on the present application belong to the scope of protection of the present application.

[0049] Currently, LED (Light Emitting Diode) display technology is booming. Its characteristics such as high brightness, high contrast, wide color gamut, and seamless splicing have promoted the wide application of LED display screens in large conference rooms, studios, monitoring and command centers, internet-famous landmarks in various cities, and various important performance activities.

[0050] During the repair and replacement process of the receiving card or display module of the LED display system, the key point is how to update the configuration parameters more efficiently and economically. The existing data read-back solution is that after replacing the receiving card or display module of the LED display system, professional technicians use control devices (such as computers or controllers, etc.) to manually update the configuration parameters of the replaced receiving card or display module through control software (such as host computer software, etc.). That is, professional technicians need to use special equipment and software to connect to the LED display control system and then send instructions to actively trigger to achieve the update of the configuration parameters, resulting in high maintenance costs and low efficiency during the repair and replacement process of the receiving card or display module of the display system.

[0051] Moreover, after replacing a certain display module in the LED display system, there will be a problem that the brightness and chromaticity of the newly replaced display module are inconsistent with those of its surrounding display modules. The existing technology is to image the LED display screen or display module through a professional camera, obtain the brightness and chromaticity of each LED lamp, generate a set of unique calibration coefficients for each pixel, and then send the calibration coefficients to the control system for storage and solidification. This method is mainly applied to unified calibration during the factory production of LED display modules or on-site full-screen calibration by users. Similarly, professional technicians are also required to use professional equipment for calibration, resulting in low repair and replacement efficiency and high maintenance costs.

[0052] To solve the above problems, the embodiments of the present application provide a display system and a display device.

[0053] In the first aspect of the embodiments of the present application, a display system is provided. Refer to Figure 1 , which is the first structural schematic diagram of the display system provided by the embodiments of the present application. The system includes: at least one display module, and the display module includes a first signal processing unit 101, a plurality of second signal processing units 102 and a plurality of display modules 103, and the second signal processing units 102 and the display modules 103 are in one-to-one correspondence. Among them, the configuration parameters of each second signal processing unit 102 in the same display module are stored in the first signal processing unit 101, and the configuration parameters of the corresponding display module 103 are stored in the second signal processing unit 102.

[0054] The first signal processing unit 101 is configured to, when a preset replacement detection condition is satisfied, read the configuration parameters from each second signal processing unit 102 in the same display module; based on the configuration parameters of each second signal processing unit 102 stored in itself, determine whether there is a target second signal processing unit 102 whose configuration parameters have changed; if so, use the configuration parameters of the target second signal processing unit 102 stored in itself to update the configuration parameters in the target second signal processing unit 102.

[0055] The second signal processing unit 102 is configured to, when a preset replacement detection condition is satisfied, read the configuration parameters from its corresponding first display module 103; based on the configuration parameters of the first display module 103 stored in itself, determine whether the configuration parameters of the first display module 103 have changed; in the case where the configuration parameters of the first display module 103 have changed, use the configuration parameters of the first display module 103 stored in itself to update the configuration parameters in the first display module 103.

[0056] In the embodiments of the present application, the display system may be an LED display system. The configuration parameters of each second signal processing unit 102 in the same display module are stored in the first signal processing unit 101, and the configuration parameters of the corresponding display module 103 are stored in the second signal processing unit 102. The configuration parameters of the display module 103 may include pixel density, image resolution, contrast, etc. The configuration parameters of the second signal processing unit 102 may include position information (for example, which row and which column in the display module), model information, cascading method, decoding method, etc.

[0057] When a certain second signal processing unit 102 of the display system fails and is repaired or replaced, when the preset replacement detection conditions are met, the first signal processing unit 101 can read the configuration parameters from each second signal processing unit 102 of the same display module, and based on the configuration parameters of each second signal processing unit 102 stored in itself, determine whether there is a target second signal processing unit 102 whose configuration parameters have changed. If so, it uses the configuration parameters of the target second signal processing unit 102 stored in itself to update the configuration parameters in the target second signal processing unit 102. It can be understood that if it is determined that there is no target second signal processing unit 102 whose configuration parameters have changed, then the faulty second signal processing unit 102 may have only been repaired and not replaced, and the configuration parameters have not changed. At this time, there is no need to update the configuration parameters of this second signal processing unit 102.

[0058] When a certain display module 103 of the display system fails and is repaired or replaced, when the preset replacement detection conditions are met, the second signal processing unit 102 corresponding to the faulty display module 103 can read the configuration parameters from the display module 103, and based on the configuration parameters of the display module 103 stored in itself, determine whether the configuration parameters of the display module 103 have changed. If they have changed, it uses the configuration parameters of the display module 103 stored in itself to update the configuration parameters in the display module 103. It can be understood that if it is determined that the configuration parameters of the display module 103 have not changed, then the faulty display module 103 may have only been repaired and not replaced, and the configuration parameters have not changed. At this time, there is no need to update the configuration parameters of the display module 103.

[0059] In the display system provided by the embodiments of the present application, during the repair and replacement process of the second signal processing unit or the display module of the display system, when the preset replacement detection conditions are met, the first signal processing unit can read the configuration parameters from each second signal processing unit of the same display module. When it is detected that the configuration parameters in the target second signal processing unit are inconsistent with the configuration parameters of the second signal processing unit stored in itself, the configuration parameters in the target second signal processing unit can be updated using the configuration parameters of the target second signal processing unit stored in itself. Moreover, the second signal processing unit can read the configuration parameters from the first display module corresponding to itself. When it is detected that the configuration parameters in the first display module are inconsistent with the configuration parameters of the first display module stored in itself, the configuration parameters of the first display module can be updated using the configuration parameters of the first display module stored in itself. That is, in the display system provided by the embodiments of the present application, during the repair and replacement process of the second signal processing unit or the display module, when the configuration parameters change, the configuration parameters can be automatically updated without the need for professional technicians to use dedicated equipment and software to connect to the display control system and send commands to actively trigger, which can reduce the maintenance cost of repairing and replacing the second signal processing unit or the display module of the display system and improve the efficiency.

[0060] In a possible implementation manner, the preset replacement detection conditions include: power-on detection and / or insertion detection.

[0061] In the embodiments of the present application, the preset replacement detection condition can be power-on detection. For example, a power-on detection module can be set in the first signal processing unit 101. When the first signal processing unit 101 is electrically connected to the second signal processing unit 102, the first signal processing unit 101 can perform detection and judgment through the power-on detection module. It can also be insertion detection. For example, an insertion detection module can be set in the second signal processing unit 102. When the second signal processing unit 102 is plugged into the display module 103, the second signal processing unit 102 can perform detection and judgment through the insertion detection module.

[0062] See Figure 2a and Figure 2b , which are the schematic diagrams before and after the parameter update of the display system when the display modules are installed and swapped. Figure 2a This is a schematic diagram of a display effect after the display modules are installed and swapped in the embodiments of the present application. Figure 2b This is a schematic diagram of the display effect after the parameter update of the display system in the embodiments of the present application. In Figure 2a and Figure 2b , the numbers in the parentheses represent the position coordinate information of the corresponding display modules. For example, (2, 1) indicates that the display module is located in the first column of the second row of all display modules. In the case of normal display, as Figure 2bAs shown in the figure, the position coordinates of the display module in the second row and the third column should be (2, 3), and the position coordinates of the display module in the third row and the second column should be (3, 2). And in Figure 2a It can be seen that if the installation positions of the two display modules at (2, 3) and (3, 2) are swapped, it will cause the problem of screen distortion on the display screen. In the related art, professionals can only implement the data read-back function in an active triggering manner by sending instructions through control software (such as host computer software, etc.), and then update the parameters, or directly re-transmit the data to make the display screen return to normal display.

[0063] In an example of the present application, the preset replacement detection condition is insertion detection, and an insertion detection module is provided in the second signal processing unit 102. When the two display modules with position coordinates (2, 3) and (3, 2) are re-inserted into their respective corresponding second signal processing units 102, the second signal processing unit 102 will use the insertion detection module to automatically read back the configuration parameters stored in the internal memory or register of the display module. When the logic processing module of the second signal processing unit 102 determines that the display module has changed after data processing, it will automatically send an instruction to send the configuration parameters of the corresponding display module stored in its storage unit to the display modules at (2, 3) and (3, 2) in the form of a data packet. After the display module updates the received configuration parameters, it can achieve normal display. The whole process does not require the participation of professionals, and the display system can automatically complete the data read-back and the update of the configuration parameters.

[0064] In another example of the present application, the preset replacement detection condition is power-on detection, and a power-on detection module is provided in the first signal processing unit 101. When a certain second signal processing unit 102 is repaired and replaced, after the second signal processing unit 102 is re-connected to the first signal processing unit 101 for power-on, the first signal processing unit 101 will use the power-on detection module to automatically read back the configuration parameters stored in the internal memory or register of the second signal processing unit 102. When the logic processing module of the first signal processing unit 101 determines that the second signal processing unit 102 has changed after data processing, it will automatically send an instruction to send the configuration parameters of the second signal processing unit 102 stored in its storage unit to the second signal processing unit 102 in the form of a data packet, so as to achieve the update of the configuration parameters.

[0065] For the display system provided by the embodiments of the present application, the preset replacement detection conditions include power-on detection and / or insertion detection. The first signal processing unit can automatically read back the configuration parameters in the second signal processing unit through power-on detection or power-on detection. The second signal processing unit can automatically read back the configuration parameters of the corresponding display module through power-on detection or power-on detection, providing a judgment criterion for subsequent judgment of whether the configuration parameters have changed and parameter update.

[0066] In a possible implementation, the first signal processing unit 101 is further configured to periodically acquire and store the configuration parameters in each of the second signal processing units 102 in the same display module during the display process of each display module 103.

[0067] The second signal processing unit 102 is further configured to periodically acquire and store the configuration parameters in the corresponding display module 103 during the display process of each display module 103.

[0068] In the embodiment of the present application, during the display process of the display module, the first signal processing unit 101 periodically acquires and stores the configuration parameters in each of the second signal processing units 102 in the same display module, and the second signal processing unit 102 periodically acquires and stores the configuration parameters in the corresponding display module 103, which can ensure that the first signal processing unit 101 stores the configuration parameters in each of the second signal processing units 102 in the same display module in real time, and the second signal processing unit 102 stores the configuration parameters in the corresponding display module 103 in real time.

[0069] In a possible implementation, the second signal processing unit 102 is further configured to send a replacement message for the first display module 103 to the first signal processing unit 101 in the same display module when the configuration parameters of the corresponding first display module 103 change.

[0070] The first signal processing unit 101 is further configured to, in response to the replacement message for the first display module 103, determine whether display correction for the first display module 103 is required according to the first display parameters of the first display module 103 and the second display parameters of the display modules 103 adjacent to the first display module 103; when display correction is required, calculate target display parameters according to the second display parameters, and send the target display parameters to the second signal processing unit 102 corresponding to the first display module 103, so that it can correct the first display module 103 by using the target display parameters.

[0071] In the embodiment of the present application, when the configuration parameters of the second signal processing unit 102 corresponding to its own first display module 103 change, the second signal processing unit 102 will send a replacement message for the first display module 103 to the first signal processing unit 101 in the same display module. After receiving the replacement message, the first signal processing unit 101 will determine whether it is necessary to perform display calibration on the first display module 103 according to the first display parameters of the first display module 103 and the second display parameters of each display module 103 adjacent to the first display module 103. When display calibration is required, the first signal processing unit 101 will calculate the target display parameters according to the second display parameters and send the target display parameters to the second signal processing unit 102 corresponding to the first display module 103, so that the second signal processing unit 102 can use the target display parameters to calibrate the first display module 103. It can be understood that when the first display parameters of the first display module 103 are inconsistent with the second display parameters of each display module 103 adjacent to the first display module 103, or the difference between the first display parameters and the second display parameters is greater than the preset difference, it is necessary to perform display calibration on the first display module 103; when the first display parameters of the first display module 103 are the same as the second display parameters of each display module 103 adjacent to the first display module 103, or the difference between the first display parameters and the second display parameters is less than the preset difference, it is not necessary to perform display calibration on the first display module 103.

[0072] In one example, the display parameters may include the brightness and chromaticity data of the display module. When a certain display module is repaired and replaced, there may be a problem that the brightness and chromaticity of the new display module are inconsistent with those of the surrounding display modules. Refer to Figure 3a and Figure 3b , Figure 3a which is a schematic diagram of the display effect when the brightness and chromaticity of a certain display module after replacement in the embodiment of the present application are inconsistent with those of the surrounding display modules. Figure 3b which is a schematic diagram of the display effect after display calibration in the embodiment of the present application. In Figure 2a and Figure 2b , the numbers in parentheses represent the position coordinate information of the corresponding display module. For example, (2, 1) means that the display module is located in the first column of the second row of all display modules. From Figure 3aAs can be seen, after the display module at (2, 2) is replaced, its brightness and chromaticity are inconsistent with those of the surrounding display modules, and display correction is required. At this time, the first signal processing unit 101 calculates the target brightness and chromaticity data based on the brightness and chromaticity data of the display modules at (1, 2), (2, 1), (2, 3), and (3, 2). For example, the average brightness and average chromaticity of these four display modules can be calculated to obtain the target brightness data and target chromaticity data, and the target brightness data and target chromaticity data are sent to the second signal processing unit 102 corresponding to the display module at (2, 2), so that the display module at (2, 2) can be corrected. The corrected display effect is as Figure 3b shown.
