[0044] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0045] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0046] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0047] The display system is composed of display modules as display units. A single display module at least includes a display array or display dots. The display module has the function of displaying images and videos. For example, the display module can be a display screen. Basic information will be set for each display module of the display screen before leaving the factory, for example: the basic information includes the physical position of the display module in the display system. Another example: the basic information includes the position information of the image area displayed by a single display module in the image to be displayed. This position information may include the coordinates of the vertex (for example: the upper left corner) of the image area in the image to be displayed, as well as the length and width of the image area. Based on the basic information, each display module receives an image and can determine the image area to be displayed from the image. Each display module displays the image area to be displayed, and the entire display system can display a complete image.

[0048] For the convenience of transportation and storage, the display system can be disassembled into multiple display modules, and these display modules can be spliced ​​together when the display system is needed. Sometimes, the display modules of other display systems are spliced ​​incorrectly to the target display system, causing the display system to be unable to accurately display the image. Or, when splicing the display system, the connection relationship between the display modules is wrong, which also makes the display system unable to accurately display the image. This is very inconvenient, increases the complexity of using the display system, and reduces the user experience.

[0049] Figure 1 The following is a flow chart of the method for image display provided by the embodiment of the present disclosure. Figure 1 As shown, the method includes:

[0050] S11, numbering each display module in the display system according to the data transmission sequence between the display modules to obtain a sequence number of each display module.

[0051] The data transmission sequence may be the arrangement sequence of the display modules after the display modules are connected in series using a data line. According to the data transmission sequence, the difference between the serial numbers of adjacent display modules may be the same. The display module may have a built-in chip, such as a built-in receiving card. A single display module may store the serial number in the receiving card. The serial number may include a number in the form of Arabic numerals.

[0052] S12, determining a first image area corresponding to each of the display modules according to a mapping relationship between each image area representing the image to be displayed and each of the serial numbers, and each of the serial numbers.

[0053] In the embodiment of the present disclosure, the image to be displayed can be divided into multiple image areas according to the arrangement and number of display modules in the display system, and each image area corresponds to a display module. For the convenience of description, the image area corresponding to the display module is named the first image area. For a single display system, the arrangement and number of display modules are fixed, so the serial number of the display module in a single display system can represent the physical position of the display area in the display system.

[0054] For example, the display system includes nine display modules, and the display modules are arranged as follows: three display modules in the top row, three display modules in the middle row, and three display modules in the bottom row. Then the image to be displayed can be divided into nine image areas, three image areas in the top row, three image areas in the middle row, and three image areas in the bottom row. In this way, each display module can correspond to one image area.

[0055] For example, the display system includes four display modules, and the display modules are arranged in sequence from left to right. Then the image to be displayed can be divided into four image areas from left to right. Each display module can correspond to one image area.

[0056] In the embodiment of the present disclosure, the mapping relationship may represent the correspondence between each serial number and the image region. Thus, a single display module may determine the image region corresponding to the serial number in the mapping relationship according to its own serial number as the first image region corresponding to the single display module.

[0057] The mapping relationship may include the starting position coordinates and the ending coordinates of the image region intercepted from the image to be displayed, or include the starting position coordinates of the image region intercepted from the image to be displayed and the length and width of the intercepted image region.

[0058] S13: Display each of the first image areas on a corresponding display module.

[0059] Figure 2Schematic diagram of a display system and an image to be displayed provided in an embodiment of the present disclosure. The display system is composed of four display modules. The display modules are arranged as follows: two display modules in the first row and two display modules in the second row. The connection relationship is that the two display modules in the first row are interconnected, the display module on the right side of the first row is interconnected with the display module on the left side of the second row, and the two display modules in the second row are interconnected. In this way, the serial number of the display modules can be as follows: Figure 2 As shown, the display module on the left side of the first row is numbered 1, the display module on the right side of the first row is numbered 2, the display module on the left side of the second row is numbered 3, and the display module on the right side of the second row is numbered 4. In addition, the image to be displayed can be divided into four image areas, namely: image area a and image area b in the first row, image area c and image area d in the second row. Figure 2 , a mapping relationship can be obtained. For the convenience of explanation, the mapping relationship is represented by Table 1. Serial number 1 corresponds to image area a, so the display module with serial number 1 can display image area a; serial number 2 corresponds to image area b, so the display module with serial number 2 can display image area b; serial number 3 corresponds to image area c, so the display module with serial number 3 can display image area c; serial number 4 corresponds to image area d, so the display module with serial number 4 can display image area d.

[0060] Table 1 Mapping relationship between each image area and each serial number

[0061]

[0062] In the embodiment of the present disclosure, each image area in the image to be displayed is no longer bound to the display module, but is related to the serial number of the display module, that is, related to the position in the display system. The method in the present disclosure numbers the display modules according to the connection order, and then determines the first image area that should be displayed on the display module according to the mapping relationship and the serial number of the display module. In this way, even if the position of the display module in the display system changes, or it is switched to another display system, the first image area corresponding to each display module can be accurately determined. Therefore, in the process of assembling the display system, there is no need to limit the connection relationship of the display modules and the position in the display system, so that the efficiency of the display system assembly is improved, and the display system can accurately display the image.

[0063] In a possible implementation, the display modules in the display system are numbered according to the data transmission order between the display modules to obtain the serial number of each display module, including: for a single display module in the display system, when a numbered data packet is transmitted to the single display module, performing the following steps: parsing the numbered data packet to obtain an initial serial number; increasing or decreasing the initial serial number according to a numbering threshold to obtain the serial number of the single display module, and using the serial number of the single display module as a new initial serial number to replace the initial serial number in the numbered data packet; and passing the numbered data packet to the next display module according to the data transmission order.

[0064] The numbering data packet may include an initial serial number. Before the numbering data packet enters the display system, the initial serial number is a preset Arabic numeral. For example, the initial number can be 0 or 20. The numbering data packet is transmitted to a single display module, and the display module can parse the numbering data packet to obtain the initial serial number, and increase or decrease the initial serial number according to the numbering threshold to obtain a number, and use this number as the serial number of the single display module. And use the serial number of the single display module as the new initial serial number to replace the original initial serial number in the numbering data packet. The numbering data packet is output to the next display module that is data-connected to the single display module until the numbering data packet is transmitted out of the display system, or the last display module in the display system obtains the serial number, and the transmission of the numbering data packet is stopped.

[0065] Exemplarily, the initial number in the numbering data packet can be 0, and the numbering threshold is 1. The first display module in the display system receives the numbering data packet, parses out the sequence number 0, and can increment sequence number 0 by 1 to obtain sequence number 1, and use sequence number 1 as the sequence number of the first display module. In addition, the initial sequence number in the numbering data packet is replaced with sequence number 1. The numbering data packet is transmitted to the second display module, and the second display module can parse out the sequence number 1 from the numbering data packet, and increment sequence number 1 to 2 to obtain sequence number 2. In addition, the initial number in the numbering data packet is replaced with sequence number 2, and the numbering data packet is passed to the third display module, and so on, until the numbering data packet is transmitted out of the display system from the last display module of the display system, or the last display module obtains the sequence number and stops passing the numbering data packet.

[0066] In one example, the numbered data packets may be transmitted to each display module together with the image to be displayed.

[0067] In the disclosed embodiment, by transmitting a numbering data packet, each display module in the display system is numbered, and each display module in the display system can automatically obtain its own number without manual intervention, saving manpower. Moreover, no matter whether the display module in the display system is relocated or replaced, the display module in the display system will be renumbered, and each display module will be accurately numbered according to the data transmission sequence, which brings more flexibility to the assembly and maintenance of the display system.

[0068] In a possible implementation manner, the mapping relationship is pre-stored in each of the display modules.

[0069] In the disclosed embodiment, the mapping relationship may be stored in the display module. For example, the mapping relationship may be stored in the display module before assembling the display system. The mapping relationship may also be stored in each display module along with the serial number. In this way, after obtaining the serial number and the image to be displayed, each display module may independently determine the first image area without relying on external hardware, thereby improving the flexibility of the entire method.

[0070] In a possible implementation, the mapping relationship includes multiple sub-mapping relationships, and the first image area corresponding to each display module is determined based on the mapping relationship between each image area representing the image to be displayed and each serial number, as well as each serial number, including: obtaining a first resolution of the image to be displayed; determining a target sub-mapping relationship from the multiple sub-mapping relationships based on the first resolution; and determining each first image area based on each serial number and the target sub-mapping relationship.

[0071] The number and arrangement of the display modules that make up the display system can affect the resolution of the display system. For example, 4 display modules arranged in a row can form a first display system; 64 display modules that are the same as the display modules in the first display system constitute a second display system, with a total of eight rows, and 8 display modules in each row. The resolutions of the first display system and the second display system are different.

[0072] The number and arrangement of display modules directly affect the aforementioned mapping relationship. This means that each display system resolution can correspond to a sub-mapping relationship. In the embodiment of the present disclosure, the sub-mapping relationships corresponding to different resolutions can be used as the mapping relationship in the present disclosure. The first resolution can be directly input from the outside to each display module in the display system, for example: the first resolution and the numbered data packet are input to each display module together. For another example: each display module can identify the first resolution based on the image to be displayed. Determine the target sub-mapping relationship based on the first resolution. Identify the first image area corresponding to the serial number from the target sub-mapping relationship.

[0073] In the disclosed embodiment, the display module includes a mapping relationship (serial number and image area) corresponding to each of the screen resolutions of multiple display systems, so that the display module can be used to assemble display systems of different shapes (number and arrangement of display modules), and the connection relationship between display modules does not need to be considered during the assembly process, and the display system can also accurately display the image to be displayed, further broadening the scope of application of the method.

[0074] In a possible implementation, the method further includes: detecting a numbered data packet within a time interval between two adjacent images to be displayed; or detecting a numbered data packet after the display system is powered on; and transmitting the detected numbered data packet between the display modules in accordance with a data transmission sequence between the display modules.

[0075] Since it is inconvenient to transport the display system directly, the display modules in the display system can be disassembled, transported, and then assembled. The order of the display modules in the original display system may be disrupted during the assembly process. It is also possible that after being transported to a new location, it needs to be assembled into a display system with a different resolution from the original display system, for example: increasing or decreasing the number of display modules. In short, when at least one of the positional relationship, arrangement, and quantity of the display modules in the display system assembled at the new location changes, the numbering data packet can be detected after the display module is powered on. The display system can number each display module as soon as it is powered on, and each display module obtains the serial number in the display system where it is located, and can accurately display the image to be displayed.

[0076] In another scenario, the display system has been powered on and used normally, wherein one or more display modules fail and need to be replaced; or the receiving card in the display module needs to be replaced. Then, the new display module or the new receiving card does not have the correct serial number, so that the display system cannot accurately display the image to be displayed. In order to apply this scenario, the display system can be set to detect the numbered data packet within the time interval between receiving two consecutive display images. If the display system displays a video, the numbered data packet can be detected within the time interval between receiving two consecutive video frames. In this way, when a new display module or receiving card is added to the display system, the new display module or receiving card can quickly obtain the serial number. Since the time interval between two frames or two images can be very short, which is conducive to the millisecond level, the naked eye can hardly feel the image abnormality using the method of the embodiment of the present disclosure, so that the display system replaces the display module (receiving card) without affecting the display effect, thereby improving the user experience of users watching the display system.

[0077] In a possible implementation, before parsing the numbered data packet, the method further includes: periodically acquiring physical location information of all display modules constituting the display system; and parsing the numbered data packet when the physical location information acquired in the current cycle is different from the physical location information acquired in the previous cycle.

[0078] The physical position of the display module may be the row and column position of the display module in the display system. The physical position of the display module may characterize the adjacency relationship between the display modules. The physical position information of the display module may indicate the physical position of the display module. A single display module may correspond to an identifier, such as a number. The identifier of the display module may be stored in the display module, and the identifier of the display module may be used as the physical position information of the display module. The display system may periodically obtain the identifiers of each display module in sequence according to the data transmission order. The obtained display module identifier may indicate the physical position of the display module in the display system, and the connection relationship of each display module in the display system. The period here may be the time interval between two adjacent images to be displayed, or an interval longer than this time interval. The display system may compare the obtained identifiers of each display module with the identifiers obtained in the previous period. Since the identifiers are obtained in the order of data transmission, the identifiers may also be arranged in the order of data transmission, and the identifiers of the same arrangement order obtained twice may be compared. If the identifiers obtained twice in each arrangement order are the same, it means that the physical position of each display module in the display system has not changed in one period, then there is no need to renumber each display module, so there is no need to parse the numbered data packet. If the identifiers obtained twice are different in at least one arrangement order, it means that the physical position of the display module in the display system has changed, so the display module needs to be renumbered. The numbering data packet can be parsed and each display module can be renumbered according to the method disclosed in the present invention.

[0079] In the disclosed embodiment, before parsing the numbered data packet, it is possible to first determine whether the physical position of each display module in the display system has changed. If there is no change, there is no need to parse the data table and repeat the numbering of the display modules, thereby further improving the smoothness of the display of multiple images or videos and improving the user experience.
