Description

Technical Field

[0001] The embodiments of the present application relate to display technology, and more specifically, to an image display method, a display device, and a storage medium. Background Art

[0002] The display screen of the display device may include at least one box, and each box may include multiple display modules (such as a light board or a TFT substrate). Each display module may be connected to the processor of the display device through its corresponding connection module, and data may be transmitted between the connection module and the processor of the display device.

[0003] Taking the display module as a light board as an example, for any light board, the connection module corresponding to the light board can be a socket set on the light board, and the other end of the socket is connected to the HUB board corresponding to the box. Therefore, if the multiple sockets are more dispersed, the size of the HUB board corresponding to the box will be larger, which will lead to lower efficiency in producing the HUB board. Taking the display module as a TFT substrate as an example, for any TFT substrate, the connection module corresponding to the TFT substrate can be a TCON board connected to the TFT substrate. However, because adjacent TCON boards are also connected by connecting wires, the more dispersed the TCON boards are, the longer the connecting wires between the TCON boards will be, which will lead to poor safety.

[0004] Therefore, how to reduce the dispersion between the above-mentioned connection modules is an urgent problem to be solved. Summary of the invention

[0048] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0049] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0050] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0051] The display device may include a display screen and a processor. The display screen of the display device may include at least one box, and each box may include multiple display modules. Each display module may be connected to the processor of the display device through its corresponding connection module, and data may be transmitted between the connection module and the processor of the display device. Taking the display device as a passive (PM) display device as an example, the display module may be a light board, and the connection module may be a socket. Taking the display device as an active (AM) display device as an example, the display module may be a thin film transistor (TFT) substrate, and the connection module may be a logic board (Timer Control Register, TCON).

[0052] Taking passive display devices as an example, Figure 1 Figure 1 is a schematic diagram of the structure of a passive display device. Figure 1 As shown, the display device may include a display screen, a HUB board, and a processor. The display screen of the display device may include at least one box (it should be understood that Figure 1 This is just an exemplary description of the structure of the display device using multiple cabinets as an example). Each cabinet corresponds to a HUB board.

[0053] Each box can include multiple light panels ( Figure 1 (not shown). For any light board, a socket may be provided on the light board, and the other end of the socket is connected to the HUB board. The light board can be connected to the processor through the socket. The socket can serve as a signal transmission channel between the processor and the light board. In other words, the processor can transmit data with the light board through the socket (for example, the processor can send data required for image display to the light board through the socket).

[0054] For any box of the display screen, when the box includes multiple light boards, each light board can be provided with a socket, so there can be multiple sockets. The more dispersed the distribution of the multiple sockets is (that is, the greater the dispersion), the larger the size of the HUB board corresponding to the box will be. The larger the size of the HUB board, the longer the movement distance of the robotic arm used to make the HUB board on the production line during the production of the HUB board, which will lead to lower efficiency in producing the HUB board. The lower efficiency in producing the HUB board will result in lower production efficiency of the display device. Therefore, how to reduce the dispersion of the display module (that is, the above-mentioned light board) of the passive display device is a crucial issue.

[0055] Take a display cabinet as an example. Figure 2 The following is a schematic diagram of the dimensions of an existing cabinet and HUB board. Figure 2As shown, in the existing display device, for any lamp board, the socket of the lamp board is centrally arranged on the lamp board. In the existing implementation, although the area of ​​the HUB board is smaller than the area of ​​the box, the size of the HUB board is still relatively large because the lamp boards are relatively dispersed.

[0056] Figure 3 This is another existing box and HUB board size diagram. Figure 3 As shown, the existing box includes two types of light panels, type A and type B. Among them, the type A light panel is provided with a socket at position 1, and the type B light panel is provided with a socket at position 2. Figure 3 The light board splicing method shown can reduce the distance between the sockets on the A-type light board and the sockets on the B-type light board, so that the dispersion of the light boards is lower, thereby reducing the size of the HUB board. In other words, the existing passive display device needs to use different types of light boards with offset sockets to reduce the dispersion of the light boards and thus reduce the size of the HUB board.

[0057] However, because the existing passive display device includes two different types of lamp boards, the production process of the passive display device requires the production of two different types of lamp boards. Therefore, the production efficiency and compatibility of the lamp boards of the existing passive display device are low, and the subsequent lamp board spare parts design is more likely to be wrong.

[0058] Taking an active display device as an example, any housing of the active display device may include multiple TFT substrates. For any TFT substrate, the TFT substrate may be connected to a processor of the display device through a connection module TCON corresponding to the TFT substrate. For example, Figure 4 This is a schematic diagram of the structure of an active display device provided by this application. Figure 4 As shown, AM-TFT represents a TFT substrate of an active display device. For any housing of the display device, the housing may include two TFT substrates, for example Figure 4 Panel 1 and Panel 2 are shown in FIG. Among them, TCON1 is the connection module of Panel 1, and TCON2 is the connection module of Panel 2. In an active display device, TCONs are also connected by connecting wires. For example Figure 4 The TCON2 shown in the figure is connected to TCON1, and TCON1 is connected to the processor, thereby realizing data transmission between TCON2 and the processor.

[0059] However, because adjacent TCON boards are also connected via connection lines, the more dispersed the TCON boards are (that is, the higher the dispersion), the longer the connection lines between the TCON boards will be, which will lead to poor security.

[0060] Therefore, in summary, how to reduce the dispersion between the connection modules of the display device is an urgent problem to be solved.

[0061] Considering the above problems existing in the existing display devices, the present application proposes a display device including a plurality of pairs of display modules, wherein the connection modules corresponding to each display module are located on a side close to the junction of the pair of display modules. With the display device, since each connection module is located close to the junction of the pair of display modules, the dispersion of the connection modules is reduced.

[0062] Optionally, the display device may be, for example, a smart TV, a smart interactive tablet, an electronic whiteboard, or any other display device with processing capabilities. It should be understood that the display device may be, for example, an active (AM) display device, or a passive (PM) display device, and this application does not limit this. The display screen may be a direct display or a backlight display, and is also applicable to a MiniLED display or a MicroLED display. Exemplarily, the processor may be, for example, a system-on-chip (SoC) of the display device. In addition, it should be understood that Figure 1 , Figure 2 , Figure 3 , Figure 4 These are all exemplary descriptions of the display device, and the present application does not limit the number of boxes, light boards, TFT substrates, etc. included in the display screen of the display device.

[0063] For example, Figure 5 This is a schematic diagram of the structure of a display device provided in this application. Figure 5 As shown, the display device may include: a display screen, and a processor. The display screen may include at least one box. For any box, the box may include at least one group of modules, and each group of modules may include: two identical display modules (e.g. Figure 5 ), and a connection module of the display modules (eg Figure 5 A first connecting module in the first display module, a second connecting module in the second display module).

[0064] Taking the display module as a light board as an example (that is, taking the display device as a passive display device as an example), the connection module (that is, the socket) of the display module can be set in the display module. Taking the display module as a TFT substrate as an example (that is, taking the display device as an active display device as an example), the connection module (that is, the TCON board) of the display module can be connected to the display module through a connecting line.

[0065] In any group of modules, the two identical display modules are centrally symmetrical and connected. The connection module is close to the connecting edge of the two display modules. For any display module, the display module can be connected to the processor through its corresponding connection module. For example Figure 5 The first display module shown in the figure can be connected to the processor via a first connection module. The second display module can be connected to the processor via a second connection module. The processor can be used to send image data to each display module and control each display module to display an image according to the image data.

[0066] Optionally, the two identical display modules being centrally symmetrical may mean that one of the two identical display modules can be obtained by rotating the other display module 180 degrees, or the two identical display modules are spliced ​​in a forward and reverse diagonal form (an asymmetric design method).

[0067] In some embodiments, the display module may include multiple display areas. Optionally, the present application does not limit the number of display areas included in the display module. Taking the display module including multiple display areas as an example, optionally, the display device may, for example, simultaneously send image data of each display area to each display area of ​​all display modules. Alternatively, the display device may also send image data of the display area included in the display module to each display module in turn.

[0068] In some embodiments, the display module can display images in a preset display order. The display order may be related to a relative position relationship. The relative position relationship is the relative position relationship between the display module and other display modules connected to it in the box. Figure 5 Taking the first display module in the example, optionally, the display order of the first display module and the second display module may be related to the relative position relationship between the first display module and the second display module in the box.

[0069] Exemplarily, the above relative position relationship may be, for example, a vertical position relationship. Figure 5 The first display module shown in the figure is above the second display module. Alternatively, the above relative position relationship can also be, for example, a left-right position relationship, etc., which is not limited in the present application. For example, the relative position relationship between the display module and other display modules connected to it in the box can also be that the first display module is on the left of the second display module, etc.

[0070] With the above Figure 5Taking the relative position relationship (upper and lower position relationship) shown in as an example, optionally, the display order of the first display module may be, for example, from the display area on the upper side of the first display module to the display area on the side adjacent to the second display module. The display order of the second display module may be, for example, from the display area on the side adjacent to the second display module to the display area on the lower side of the second display module.

[0071] Taking the above relative position relationship of left and right as an example, optionally, the display order of the two display modules in the group of display modules may be, for example, the order of displaying images in the display area from top to bottom.

[0072] In this embodiment, the two display modules in each group of modules of the display device are identical, and the identical two display modules are connected. The connection module of each display module is close to the connecting edge of the two display modules. Through the above method, the distance between different connection modules is made smaller, thereby reducing the dispersion between the connection modules. By reducing the dispersion between the connection modules, for passive display devices, the size of the HUB board can be reduced, thereby improving the production efficiency of the HUB board; for active display devices, the distance between TCON boards is reduced, thereby improving the safety of the display device.

[0073] Based on the display device provided by the present application, the present application also provides an image display method, through which an image is displayed. The execution subject of the image display method can be the display device (or the processor of the display device).

[0074] The following takes the execution subject of the image display method as a display device as an example, and describes the technical solution of the present application in detail in combination with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0075] Taking the display device as a passive display device, the two identical display modules are the first light board and the second light board, and the connecting module is a socket as an example, as a possible implementation method, the first light board and the second light board can both include at least one driving unit, and each driving unit can correspond to a display area.

[0076] As a possible implementation, for example, Figure 6 A schematic diagram of a group of modules provided by the present application. Among them, the connection modules of each display module are Figure 6 Not shown. Figure 6 As shown, the display module (first light board) above and the display module (second light board) connected thereto include identical driving units. The driving unit may be, for example, Figure 6The IC chips (full name is Integrated Circuit Chip) shown in: for example, IC1 to IC12.

[0077] The display device may send the image data of the display area corresponding to the driving unit to each driving unit in sequence according to a preset data transmission sequence.

[0078] Optionally, for different display modules, the order in which the display device sends image data to the drive units of different display modules may be the same or different. For example, the order in which the display device sends image data to the drive units of different display modules is the same. Figure 6 As shown, the display device can, for example, send the image data of the display area corresponding to the drive unit to each drive unit at one time through the connection module of the display module above in the order of IC1-IC2-IC3-IC4-IC12-IC11-IC8-IC7-IC10-IC9-IC5-IC6. For the display module connected thereto, the display device can also send the image data of the display area corresponding to the drive unit to each drive unit at one time through the connection module of the display module connected thereto in the order of IC1-IC2-IC3-IC4-IC12-IC11-IC8-IC7-IC10-IC9-IC5-IC6.

[0079] In some embodiments, after sending the above-mentioned image data to each driving unit, the display device can also send feedback data to the connection module corresponding to the display module where the driving unit is located through the last driving unit that obtains the image data (for example, IC6 sends feedback data to the socket), so that the processor can obtain the above-mentioned feedback data through the connection module, and determine that each driving unit of the display module has received the image data based on the feedback data.

[0080] The display device may control the first light board to display images according to the first display order based on the image data, and control the second light board to display images according to the second display order based on the image data. The first display order may be from the display area of ​​the "opposite side of the adjacent side" of the first light board to the display area of ​​the adjacent side. The second display order may be from the display area of ​​the adjacent side of the second light board to the display area of ​​the "opposite side of the adjacent side".

[0081] by Figure 6For example, the display area of ​​the "opposite sides of the adjacent sides" of the above-mentioned first light board may refer to, for example, the display area corresponding to IC5 and the display area corresponding to IC9; the display area of ​​the adjacent sides may refer to, for example, the display area corresponding to IC4 and the display area corresponding to IC12. That is to say, for this display module, the preset display order of the display module may be, for example, IC5—IC9—IC6—IC10—IC1—IC7—IC2—IC8—IC3—IC11—IC4—IC12. For the display module (second light board) connected to the display module, the display order of the display module is the above-mentioned second display order, for example, it may be: IC12—IC4—IC11—IC3—IC8—IC2—IC7—IC1—IC10—IC6—IC9—IC5.

[0082] In this embodiment, the two light boards in a group of modules are two completely identical light boards. Through the above display device, when producing the display device, only one type of display module needs to be produced, thereby improving the production efficiency and matching of the connection module of the existing display device, and reducing the possibility of errors in the subsequent light board spare parts design. And through the above image display method of the first display sequence and the second display sequence, the display effects of the first light board and the second light board are the same, which improves the user experience.

[0083] In some embodiments, for any driving unit, if the display device determines that the driving unit has received the image data of the display area corresponding to the driving unit, and determines that the image display order of the display area corresponding to the driving unit has not yet arrived according to the above display order, the driving unit is controlled to cache the image data of the corresponding display area. The display order mentioned here can be the first display order or the second display order mentioned above. Taking the first light board as an example, the display order is the first display order. Taking the second light board as an example, the display order is the second display order.

[0084] Through the above method, the driving unit that receives the image data first will not immediately control the corresponding display area to display the image, but when it is the turn of the driving module to display the image in the corresponding display area according to the display order, it can display the image according to the cached image data, thereby improving the accuracy of image display and further improving the user experience.

[0085] For example, Figure 6Take the driving unit IC1 shown in as an example, according to the data transmission order of IC1-IC2-IC3-IC4-IC12-IC11-IC8-IC7-IC10-IC9-IC5-IC6, IC1 receives the image data first. However, according to the display order of IC5-IC9-IC6-IC10-IC1-IC7-IC2-IC8-IC3-IC11-IC4-IC12, the display area corresponding to IC1 needs to display the image after IC5, IC9, IC6, and IC10 have all received the image data and displayed the image. Therefore, the display device can control IC1 to cache the image data of the corresponding display area, so that when it is IC1's turn to display according to the above display order, the image is displayed according to the cached image data.

[0086] In some embodiments, for any group of modules, the electronic device may also first determine the first moment when each driving unit in the first light board receives the image data of the corresponding display area, and the second moment when each driving unit in the second light board receives the image data of the corresponding display area. Then, the display device may determine the first time difference (also referred to as a synchronization control bit in some embodiments) between the first light board and the second light board for displaying the image based on the first moment and the second moment.

[0087] Then, the display device can control the first light board and the second light board to display images according to the first time difference. For example, the display device can send the first time difference to the first light board and the second light board so that the first light board and the second light board display images according to the first time difference.

[0088] For example, Figure 7 This is a schematic diagram of the time difference when each driving unit in a different light board receives the image data of the corresponding display area provided by the present application. Figure 7 As shown, assuming that the moment when each driving unit in the first light board receives the image data of the corresponding display area is a, and assuming that the moment when each driving unit in the second light board receives the image data of the corresponding display area is b, then the above-mentioned first time difference is the first time difference between moment a and moment b.

[0089] Optionally, the display device can control the first light board and the second light board to start displaying images at the same time according to the first time difference, thereby improving the consistency of image display. Figure 7 For example, time a is before time b, that is, the first light board receives the image data earlier than the second light board. Therefore, the display device can control the first light board and the second light board to start displaying images at the same time at time b after the first time difference after each driving unit of the first light board receives the image data of the corresponding display area.

[0090] In this embodiment, for two light boards in a group of light boards, the two light boards can be controlled to start displaying images at the same time according to the first time difference when each driving unit in the two light boards receives the image data. Through the above method, the asynchronism within the light board and between the light boards, especially the asynchronism problem under shooting conditions, is solved, so that any group of light boards can start displaying images at the same time, which improves the consistency of image display and further improves the user experience.

[0091] Further, optionally, the display device can also control the first light board and the second light board to display a black field of a first preset duration after displaying each frame of image data, so as to perform black field correction. The first preset duration can be relatively short, because of the visual residual effect, the actual display effect of the user watching the display device makes the user unable to distinguish the existence of the black field, and does not affect the user's viewing experience. Exemplarily, the display device can control the light board to display a black field by controlling the level of the light board to be all low.

[0092] It should be understood that the present application does not limit the content of the above image data. Figure 8 A schematic diagram of image data displayed on a display screen. Figure 8 As shown, each square is used to represent the display area corresponding to a light board. Figure 8 As shown in (a) of FIG. 1 , taking the display area of ​​the first light board as an example, the light board can display black. Assume that the light board in a group with the first light board is Figure 8 The second light board shown in Figure 8 In (b), the second light board can display black.

[0093] Then, the display device can obtain the third moment when the first light board starts to display the black field, and the fourth moment when the second light board starts to display the black field. The third moment can also be used to represent the moment when the first light board finishes displaying a frame of image data. The fourth moment can also be used to represent the moment when the second light board finishes displaying a frame of image data.

[0094] The display device can determine the second time difference between the first light board and the second light board for displaying images based on the third moment and the fourth moment. For example, the display device can use the absolute value of the time difference between the third moment and the fourth moment as the second time difference. If the third moment is before the fourth moment, the second time difference can be used to characterize that the moment when the first light board finishes displaying a frame of image data is earlier than the moment when the second light board finishes displaying a frame of image data by the second time difference. If the third moment is after the fourth moment, the second time difference can be used to characterize that the moment when the first light board finishes displaying a frame of image data is later than the moment when the second light board finishes displaying a frame of image data by the second time difference.

[0095] Then, the display device can control the first light board and the second light board to display images according to the above-mentioned first time difference and the second time difference. For example, the display device can control the first light board and the second light board to start displaying images at the same time according to the above-mentioned first time difference, and the display device can control the first light board and the second light board to end displaying a frame of image data at the same time according to the second time difference. Taking the above-mentioned third moment before the fourth moment as an example, the display device can delay the duration of the first light board displaying the frame of image data, so that the first light board displays the frame of image data until the fourth moment, and starts to display the above-mentioned black field at the fourth moment. At the same time, the display device can control the second light board to display the frame of image data The duration remains unchanged (that is, displays the frame of image data until the fourth moment, and starts to display the above-mentioned black field at the fourth moment).

[0096] In this embodiment, through the above-mentioned second time error, the display device can determine at what times the first light board and the second light board can complete the display respectively. That is to say, according to the difference in image display efficiency of different light boards, different light boards are controlled to display images, thereby further improving the consistency of image display and further improving the user experience.

[0097] Taking the display device as an active display device as an example, the display module may include at least one display area, the two identical display modules may be a first TFT substrate and a second TFT substrate, and the connection module is TCON. In this example, as a possible implementation, for any group of modules, the display device may control the first TFT substrate to display images in the order from the display area at the opposite side of the connecting edge to the display area at the connecting edge. The display device may control the second TFT substrate to display images in the order from the display area at the connecting edge to the display area at the opposite side of the connecting edge.

[0098] For example, Fig. 9 This is a schematic diagram of an active display device provided by the present application. Fig. 9 As shown, AM-TFT panel 1 may be a first TFT substrate, TCON1 may be a connection module corresponding to the first TFT substrate, AM-TFT panel 2 may be a second TFT substrate, and TCON2 may be a connection module corresponding to the second TFT substrate.

[0099] In some embodiments, the display device can control the gate signal output by the first TFT substrate corresponding to the connection module by means of shift register, so that the first TFT substrate is accumulated according to the preset number of rows to the number of rows corresponding to the display area at the connecting edge. Optionally, in this process, the source signal output by the connection module can refer to any existing implementation method, which will not be described in detail in this application.

[0100] Exemplarily, assuming that the first TFT substrate includes n rows of display areas, the display device can refer to any existing TCON gate signal output method to control the connection module TCON of the first TFT substrate to output a gate signal so that the first TFT substrate accumulates (for example, adds 1 row each time) a preset number of rows, for example, the first row, to the number of rows corresponding to the display area at the adjacent edge (for example, the nth row), so that the first TFT substrate can realize image display from the opposite side of the adjacent edge to the display area of ​​the adjacent edge.

[0101] In some embodiments, the display device may control the second TFT substrate to display images in a sequence from a display area at the adjacent edge to a display area at the opposite edge of the adjacent edge by reverse shifting.

[0102] Exemplarily, it is assumed that the second TFT substrate includes n rows of display areas. Fig. 9 For example, the display device can control the gate corresponding to TCON2 to start from n, that is, from the nth row (the display area of ​​the adjacent edge) to n-1, n-2...1 row. In this implementation mode, after the display device is powered on, it can first synchronize the gate to accumulate according to the preset number of rows until it overflows after accumulating to n (after accumulating to n, the overflow number is increased by 1 each time it is accumulated). For each increase in overflow data, the display device can control TCON2 to shift in the reverse direction, that is, subtract the overflow data from n, to realize the display area at the adjacent edge to the display area at the opposite side of the adjacent edge in order to display the image. In addition, the display device can also control and coordinate TOCN1 and TCON2 to enable the first TFT substrate and the second TFT substrate to display synchronously.

[0103] In this embodiment, the second TFT substrate is controlled to display images in the order from the display area at the connecting edge to the display area at the opposite edge of the connecting edge by reverse shifting, so that each TFT substrate in the active display device can display in a unified display mode, while reducing the dispersion between the connection modules, ensuring the consistency of image display of each TFT substrate (it can also be said to achieve the delay between the TFT substrates), and improving the user experience. In addition, for the TFT substrate, by reducing the dispersion between the connection modules, each TFT substrate can be concentrated at a centralized location, which improves the simplicity of installation and structural design.

[0104] As another possible implementation, still taking the display device as an active display device as an example, the processor can also first perform frequency doubling processing on the image data of each display area to obtain frequency-doubled image data. The frequency-doubled image data can include: original image frame data, and interpolated frame data. Then, for any group of display modules, the display device can control the first TFT substrate to display the original image frame data, and the second TFT substrate to display the interpolated frame data. Alternatively, the display device can control the first TFT substrate to display the interpolated frame data, and the second TFT substrate to display the original image frame data.

[0105] Optionally, the method for the display device to perform frequency doubling processing on the image data can refer to any existing frequency doubling processing method, and this application will not repeat it here. Exemplarily, the display device can, for example, perform double frequency doubling on the above image data. For example, assuming that the original frame rate of the image data is 64 Hz, the image data after frequency doubling can be 128 Hz.

[0106] For example, Fig.10 This is a schematic diagram of a display of frequency-multiplied image data provided by the present application. Fig.10 As shown, the A1 frame, A2 frame, A3 frame, and A4 frame are all image data displayed on the first TFT substrate. The B1 frame, B2 frame, B3 frame, and B4 frame are all image data displayed on the second TFT substrate. Among them, the image data of the A1 frame, A3 frame, B2 frame, and B4 frame are all original image frame data. The image data of the B1 frame, A2 frame, B3 frame, and A4 frame are all supplementary frame data. Fig.10 As shown, the display device can control the second TFT substrate to display the supplementary frame data (for example, B1 frame image data) when the first TFT substrate displays the original image frame data (for example, A1 frame image data). The display device can control the second TFT substrate to display the original image frame data (for example, B2 frame image data) when the first TFT substrate displays the supplementary frame data (for example, A2 frame image data).

[0107] In this embodiment, the frequency-doubled image data is displayed alternately by the first TFT substrate and the second TFT substrate, so that the display result of the display screen can avoid the display range of the human eye according to the visual residual effect, thereby enabling the display device to achieve consistency in the display module display in terms of visual effect, thereby improving the user experience.

[0108] Fig.11 This is a schematic diagram of the structure of an image display device provided in an embodiment of the present application.

Among them, the first display order is from the display area of ​​the opposite side of the adjacent edge of the first light board to the display area of ​​the adjacent edge; the second display order is from the display area of ​​the adjacent edge of the second light board to the display area of ​​the opposite side of the adjacent edge.

The display order is the first display order or the second display order.

[0113] Optionally, the processing module 22 is also used to determine, for any group of modules, a first moment when each driving unit in the first light board receives the image data of the corresponding display area, and a second moment when each driving unit in the second light board receives the image data of the corresponding display area; determine a first time difference between the first light board and the second light board for image display based on the first moment and the second moment; and control the first light board and the second light board to display images based on the first time difference.

The frequency-doubled image data includes: the original image frame data, and the supplementary frame data.
