[0062] In electronic blackboard splicing display products, multiple display modules are typically spliced together to form a large electronic blackboard. While these modules can display both the same and different content, they lack interaction between the modules. Furthermore, the modules are not integrated, so it's impossible to ensure they are aligned horizontally or vertically, resulting in large gaps between the electronic blackboards.
[0063] In order to solve at least one of the above technical problems, the first aspect of the embodiment of the present disclosure proposes a splicing display module, which includes: a plurality of display modules spliced together, the display module having a splicing side; the display module includes a back plate, a display panel, a cover plate and a first fixing member; the display panel and the cover plate are arranged on the back plate in a direction away from the back plate; wherein, for one display module, the first fixing member is located on the splicing side of the display module and is arranged on the side of the cover plate facing the back plate; one end of the first fixing member is fixed to the cover plate, and the other end is fixed relative to the back plate; for any two spliced display modules, the cover plates of the two are in contact at the edge of the splicing side. The splicing display module disclosed in the present disclosure can well splice the individual display modules together and reduce the seam between adjacent display modules on the splicing side.
[0064] The display module of the embodiment of the present disclosure can be applied to an electronic blackboard, and multiple display modules can be spliced together to form a large electronic blackboard.
[0065] Figure 1a is a schematic structural diagram of a spliced display module provided by the present disclosure; Figure 1b is a schematic structural diagram of the spliced display module shown in Figure 1a omitting the cover plate and display panel; and Figure 1c is a spliced cross-sectional view of the spliced display module shown in Figure 1a . The spliced cross-sectional view shown in Figure 1c is obtained by splicing the cross-sectional views of each cross section together, taken along the AA, BB, CC, and DD directions in Figure 1a .
[0066] In the examples shown in Figures 1a to 1c, the spliced display module includes: a plurality of display modules 1 spliced together, the display module having a splicing side S; the display module 1 includes a back panel 10, a display panel 20, a cover panel 30 and a first fixing member 40; the display panel 20 (not shown in Figures 1a to 1c) and the cover panel 30 are arranged on the back panel 10 in a direction away from the back panel 10; wherein, for one display module 1, the first fixing member 40 is located on the splicing side S of the display module and is arranged on the side of the cover panel 30 facing the back panel 10; one end of the first fixing member 40 is fixed to the cover panel 30, and the other end is fixed to the back panel 10; for any two spliced display modules 1, the cover panels 30 of the two are in contact at the edges of the splicing side S.
[0067] FIG2 is a schematic diagram of the structure of the first fixing member 40 of the spliced display module provided by the present disclosure. In some examples, as shown in FIG2 , the first fixing member 40 includes a first fixing assembly 41 and a second fixing assembly 42. The first fixing assembly 41 includes a first connecting portion 411, a second connecting portion 412, and a third connecting portion 413 connecting the first connecting portion 411 and the second connecting portion 412. The second fixing assembly 42 is located on the side of the third connecting portion 413 facing away from the display panel 20. The first connecting portion 411 is fixedly connected to the cover plate 30. The third connecting portion 413 is fixedly connected to the second fixing assembly 42. The second connecting portion 412 is located between the back plate 10 and the second fixing assembly 42, and the three are fixedly connected.
[0068] There are various ways of fixing the connection between the third connection part 413 and the second fixing component 42, between the second connection part 412, the back panel 10 and the second fixing component 42, and between the first connection part 411 and the cover plate. The following examples illustrate the ways of fixing the connection between the third connection part 413 and the second fixing component 42, between the second connection part 412, the back panel 10 and the second fixing component 42, and between the first connection part 411 and the cover plate. It should be understood that the examples described here are only used to illustrate and explain the present disclosure and are not used to limit the present disclosure.
[0069] Specifically, the first connection portion 411 and the cover plate can be fixedly connected via an adhesive layer. The adhesive layer can be made of, but is not limited to, foam and can also be made of other materials with adhesive properties.
[0070] The second connecting portion 412, the back plate 10, and the second fixing assembly 42 are fixedly connected by a first fastener 43. The first fastener 43 can be a screw, and the second connecting portion 412, the back plate 10, and the second fixing assembly 42 have threads corresponding to the screw, and the second connecting portion 412, the back plate 10, and the second fixing assembly 42 are fixedly connected together by the screw.
[0071] The third connection portion 413 is fixedly connected to the second fixing assembly 42 via a second fastener 44. The second fastener 44 may be a screw, and a thread corresponding to the screw is provided at a corresponding position on the second fixing assembly 42, and the third connection portion 413 is fixedly connected to the second fixing assembly 42 via the screw.
[0072] Through the above-mentioned fixed connection method, a detachable connection method can be achieved between the third connection part 413 and the second fixing component 42, between the second connection part 412, the back panel 10 and the second fixing component 42, and between the first connection part 411 and the cover plate, which is convenient for subsequent maintenance.
[0073] FIG3 is a schematic structural diagram of the second fixing member of the splicing display module provided by the present disclosure. In some examples, the display module 1 further has a non-splicing side S'. As shown in FIG3 , the display module 1 has a second fixing member 50 on the non-splicing side; the second fixing member 50 includes a third fixing component 51 and a fourth fixing component 52. The third fixing component 51 includes a first fixing structure 511 and a second fixing structure 512 that are connected to each other; the first fixing structure and the second fixing structure can be an integral structure. The first fixing structure 511 is located on the side of the cover plate 30 facing the back plate 10, and one end is fixed to the cover plate 30 and the other end is fixed to the back plate 10; the second fixing structure 512 protrudes from the cover plate 30 and has a first receiving groove 5121 facing the display area. A first light bar 5122 is provided in the first receiving groove 5121. The light-emitting element 5123 in the first light bar 5122 protrudes from the cover plate 30 to facilitate the light-emitting element 5123 to emit light. The fourth fixing assembly 52 includes a fourth connecting portion 521, a fifth connecting portion 522, and a sixth connecting portion 523 connecting the fourth and fifth connecting portions 521 and 522. The third fixing assembly 51 is located on the side of the sixth connecting portion 523 facing away from the display panel 20. The fourth connecting portion 521 is fixedly connected to the cover plate 30; the sixth connecting portion 523 is fixedly connected to the third fixing assembly 51. The fifth connecting portion 522 is located between the back plate 10 and the first fixing structure 511 of the third fixing assembly 51, and the three are fixedly connected. The third and fourth fixing structures provide support for the cover plate 30, improving the reliability of the display module.
[0074] FIG4 is a partial enlarged schematic diagram of the spliced display module shown in FIG1a in the M area. In some examples, as shown in FIG4 , the light-emitting element 5123 has a light-emitting area. In the example disclosed herein, the light-emitting element is an infrared light-emitting element, and the effective light-emitting area is 80° as an example for description. In any two adjacent display modules, the orthographic projections of the two adjacent first fixing members 40 on the first plane and the orthographic projections of the two light-emitting areas of the two adjacent light-emitting elements 5123 on the first plane do not overlap; wherein the first plane is the plane where the backplane is located. Through this setting method, the first fixing member can be prevented from blocking the light emitted by the light-emitting element 5123 on the splicing side, thereby affecting the splicing effect.
[0075] In some examples, to avoid touch failure, in any two adjacent display modules 1, the distance between the two adjacent first light bars 5122 is less than 16 mm. More specifically, the first light bar 5122 includes a driving circuit board and a light-emitting element 5123 arranged on the driving circuit board. In any two adjacent display modules 1, the distance between the driving circuit boards of the two adjacent first light bars 5122 is less than 16 mm, for example, 1 mm, 2 mm, 3.5 mm, 5 mm, 6 mm, 7.8 mm, 10 mm, 12 mm, etc. The driving circuit board can be a PCB (Printed Circuit Board). By reasonably setting the distance between the driving circuit boards of the first light bars 5122 of adjacent display modules 1, the occurrence of invalid touch areas, that is, the occurrence of areas not covered by the light emitted by the light-emitting element 5123, can be effectively avoided.
[0076] In some examples, in order to avoid touch failure, in any two adjacent display modules 1, the distance between the light-emitting elements 5123 of two adjacent first light bars 5122 is less than 20 mm, for example, 1 mm, 2 mm, 3.5 mm, 5 mm, 6 mm, 7.8 mm, 10 mm, 12 mm, 15 mm, 16 mm, 18 mm, etc.
[0077] In some examples, as shown in Figures 3 and 4, a first filter strip 5124 is fixed at the opening of the first receiving groove 5121. In any two adjacent display modules 1, there is a seam between the two adjacent first filter strips 5124. To prevent the seam from affecting the display failure of the display module, in any two adjacent display modules 1, for the seam between the two adjacent first filter strips 5124 and the two adjacent light-emitting elements 5123, the light emitted by the two light-emitting elements 5123 does not pass through the seam between the two first filter strips 5124.
[0078] Figure 5 is a partial schematic diagram of a spliced display module provided by the present disclosure. Figure 6 is a schematic diagram of the structure of the first locking buckle and the first fixing block provided by the present disclosure. In some examples, as shown in Figures 5 and 6, any two adjacent display modules 1 have a first locking buckle 60 fixed to the back panel 10 of one on the splicing side S, and a first positioning block 70 corresponding to the first locking buckle 60 fixed to the back panel 10 of the other on the splicing side S. The first locking buckle 60 and the first positioning block 70 are detachably connected.
[0079] In some examples, the first lock 60 includes: a second positioning block 61 and a connecting rod 62; wherein the second positioning block 61 is fixed to the back panel 10 and is arranged corresponding to the first positioning block 70; the connecting rod 62 is an open-loop structure, having a first end 621 and a second end 622, both of which are rotatably connected to the second positioning block 61, and the connecting rod 62 can be rotated to the side of the first positioning block 70 and fixedly connected to the first positioning block 70. The first positioning block 70 has a first groove 71 on the side facing away from the first lock 60, and the connecting rod 62 also includes a middle portion 623 connecting the first end 621 and the second end. In the spliced state, the middle portion 623 of the connecting rod 62 of the first lock 60 is stuck in the first groove 71, thereby further reducing the splicing gap between any two adjacent display modules.
[0080] In some examples, as shown in Figures 5 and 6, the first locking buckle 60 includes a second positioning block 61, a connecting rod 62, and a handle 63. The second positioning block 61 is fixed to the back panel 10 and corresponds to the first positioning block 70. The handle 63 is rotatably connected to the second positioning block 61 at its end near the first positioning block 70. The connecting rod 62 is an open-loop structure, having a first end 621, a middle portion 623, and a second end 622 connected in sequence. The first end 621 and the second end 622 are rotatably connected to the handle 63. The connecting rod 62 can rotate toward the first positioning block 70 and is fixedly connected to the first positioning block 70. In the spliced state, the middle portion 623 of the connecting rod 62 of the first locking buckle 60 is engaged in the first groove 71. The end of the handle, away from the first positioning block 70, presses down onto the back panel 10, forming a self-locking structure with the connecting rod engaged in the first groove 71. This improves the locking strength between two adjacent display modules and enhances the reliability of the entire spliced display module.
[0081] In some examples, as shown in FIG. 6 , the first lock buckle 60 further includes a rotating shaft 64 , and the first end 621 of the connecting rod 62 and the second end 622 of the connecting rod 62 are rotatably connected to the handle 63 via the rotating shaft 64 passing through the handle 63 .
[0082] In some examples, as shown in FIG6 , the first lock catch 60 further includes a third fastener 65, a fourth fastener 66, a fifth fastener 67, and a sixth fastener 68. The third fastener 65, the fourth fastener 66, the fifth fastener 67, and the sixth fastener 68 can each be a nut. The rotating shaft 64 of the first lock catch 60 has a first end 641 and a second end 642. The first end 621 and the second end 622 of the connecting rod 62 of the first lock catch 60 are both threaded. The first end 621 of the connecting rod 62 passes through the first end 641 of the rotating shaft 64. The third fastener 65 and the fourth fastener 66 are located on either side of the first end 641 of the rotating shaft 64 and are threadedly connected to the first end 621 of the connecting rod 62. The second end 622 of the connecting rod 62 passes through the second end 642 of the rotating shaft 64. The fifth fastener 67 and the sixth fastener 68 are located on either side of the second end 642 of the rotating shaft 64 and are threadedly connected to the second end 622 of the connecting rod 62.
[0083] In the spliced state, the connecting rod 62 can be prevented from moving by tightening the fifth fastener 67 and the sixth fastener 68 on both sides of the second end 642 of the rotating shaft 64, and tightening the third fastener 65 and the fourth fastener 66 on both sides of the first end 641 of the rotating shaft 64.
[0084] In the non-spliced state, the first end 621 of the connecting rod 62 has a first side 624 facing the first positioning block 70, and the second end 622 of the connecting rod 62 has a second side 625 facing the first positioning block 70. The length of the connecting rod can be adjusted by adjusting the distance between the third fastener 65 and the fourth fastener 66 and the first side 624 of the connecting rod 62, and adjusting the distance between the fifth fastener 67 and the sixth fastener 68 and the second side 625 of the connecting rod 62.
[0085] FIG7 is a schematic diagram of the structure of a spliced display module provided by the present disclosure. FIG8 is a partial schematic diagram of the spliced display module shown in FIG7 . In some examples, as shown in FIG7 and FIG8 , the spliced display module further includes: a crossbeam 80. The crossbeam 80 is disposed on the side of the back panel 10 of each display module 1 facing away from the cover panel 30, and the back panel 10 is fixed to the crossbeam 80. The crossbeam 80 ensures that each display module 1 is in the same plane in the direction in which the crossbeam 80 extends. The crossbeam 80 can be fixedly connected to the back panel 10 via a bracket 90.
[0086] In some examples, as shown in Figures 7 and 8, when processing a beam 80 that is too long, since the beam 80 is a strip-shaped piece, it is easy to deform during the processing process. Therefore, a segmented beam 80 can be used, and each segment of the beam 80 is set corresponding to a display module 1.
[0087] In some examples, to improve the strength of the beam 80, at least one first opening 81 is provided on the beam 80. In the example of the present disclosure as shown in FIG7, a plurality of first openings 81 are provided side by side along the extending direction of the beam 80.
[0088] FIG9 is a schematic diagram of a partial structure of a spliced display module provided by the present disclosure. In some examples, as shown in FIG9 , any two adjacent display modules 1 have a first latch 90 fixed on the back panel 10 of one at the splicing side S, and a slot 100 fixed on the back panel 10 of the other at the splicing side. The first latch 90 and the slot 100 can be fixedly connected. Specifically, in the spliced state, the first latch 90 is inserted into the slot 100. The first latch 90 and the slot 100 are used to limit the position of the two adjacent display modules 1, so that the cover plate 30 and the display panel 20 of each display module 1 remain consistent in the horizontal and vertical directions.
[0089] Figure 10 is a schematic diagram of the structure of a spliced display module provided by the present disclosure. In some examples, as shown in Figure 10, the display module 1 includes a control chip;
[0090] One of the display modules 1 is a first display module 101 , and the others are second display modules 102 . The control chip in the first display module 101 is a first control chip 1011 , and the control chip in the second display module 102 is a second control chip 1021 . Each second control chip 1021 is in communication with the first control chip 1011 .
[0091] The driving circuit board of the first light bar 5122 in the first display module 101 is connected to the first control chip 1 ; the driving circuit board of the first light bar 5122 in each second display module 102 is connected to the driving circuit board of the first light bar 5122 in the first display module 101 .
[0092] The first display module 101 also includes a first power cord; the second display module 102 includes a second power cord, each of which is electrically connected to the first power cord, which is connected to an external power module. The external power module can be an external power socket, an external power supply, etc., and can be a module that provides voltage.
[0093] The power cord routing method of the disclosed example is an integrated routing method, which is convenient for product use.
[0094] In some examples, the first display module 101 and the second display modules 102 located on both sides of the first display module 101 , the size of the second display module 102 is smaller than or equal to the size of the first display module 101 .
[0095] 11a to 11e are schematic diagrams of splicing of the spliced display module provided by the present disclosure.
[0096] The following describes in detail the splicing application scenario, wiring application scenario, and communication process of the first display module 101 and the second display module 102 with reference to FIG. 11 a to FIG. 11 e .
[0097] Splicing application scenarios:
[0098] In one application scenario, as shown in FIG11 a , the spliced display module includes a first display module 101 and two second display modules 102 . The two second display modules 102 are located on both sides of the first display module 101 , and the sizes of the two second display modules 102 are the same as those of the first display module 101 .
[0099] In one application scenario, as shown in Figure 11b, the spliced display module also includes a first display module 101 and four second display modules 102. The four second display modules 102 are located on both sides of the first display module 101, and the sizes of the four second display modules 102 are the same as those of the first display module 101.
[0100] In one application scenario, as shown in FIG11c , the spliced display module further includes a first display module 101 and two second display modules 102. The two second display modules 102 are located on either side of the first display module 101. The two second display modules 102 are of equal size and smaller than the first display module 101. For example, the first display module 101 is an 86-inch display module, and the second display module 102 is a 63-inch display module.
[0101] In one application scenario, as shown in Figure 11d, the spliced display module also includes a first display module 101 and four second display modules 102. The four second display modules 102 are spliced together in pairs along the width direction of the spliced display module. After splicing, the display modules are located on both sides of the first display module 101. The sizes of the four second display modules 102 are equal and all smaller than the size of the first display module 101.
[0102] In one application scenario, as shown in Figure 11e, the spliced display module also includes a first display module 101 and eight second display modules 102. The eight second display modules 102 are arranged around the first display module 101. The size of the second display modules 102 located on both sides of the first display module 101 along the splicing width direction is equal to the size of the first display module 101, and the sizes of the remaining second display modules 102 are smaller than the size of the first display module 101.
[0103] Cabling and communication application scenarios:
[0104] In the wiring application scenario, the spliced display module of the example of the present disclosure is described using the spliced display module shown in Figure 11c. Specifically, the first display module 101 has a first non-spliced side 101a, a first spliced side 101b, a second non-spliced side 101c, and a second spliced side 101d. The first non-spliced side and the second non-spliced side of the first display module 101 are opposite to each other, and the first spliced side 101b and the second spliced side 101d of the first display module 101 are opposite to each other.
[0105] The second display module 102 has a first non-joined side 102a, a second non-joined side 102b, a third non-joined side 102c, and a jointed side 102d. The first non-joined side and the third non-joined side of the second display module 102 are opposite to each other, and the second non-joined side 102b of the second display module 102 is opposite to the jointed side 102d.
[0106] The first light bars 5122 of the two second display modules 102 on the first non-joined side 102a are electrically connected to the first light bar 5122 of the first display module 101 on the first non-joined side 101a. The first light bars of the two second display modules 102 on the third non-joined side 102c are electrically connected to the first light bar 5122 of the first display module 101 on the third non-joined side 101c. The first light bar 5122 of the first display module 101 on the first non-joined side 101a is electrically connected to the first light bar 5122 of the first display module 101 on the third non-joined side 101c. The first light bar 5122 of the first display module 101 on the first non-joined side 101a or the first light bar 5122 of the first display module 101 on the third non-joined side 101c is electrically connected to the first control chip 1011. The first control chip 1011 of the first display module 101 is electrically connected to the second control chip 1021 of the second display module 102.
[0107] In the disclosed example, the first light bars 5122 of each display module form a segmented routing method, which is conducive to the assembly of the display module and avoids the problem of touch failure caused by the excessive length of the spliced display module in the splicing direction.
[0108] In some examples, because the size of the splicing display module in the splicing direction is too long, the light-emitting elements on the first light strips on both sides of the splicing display module in the splicing direction are difficult to align, resulting in touch failure. In order to solve this problem, a first fixing member is used on both sides of the splicing display module in the splicing direction instead of using a second fixing member on both sides of the splicing display module in the splicing direction, which effectively avoids the light-emitting elements on the first light strip of the third fixing component of the second fixing member on both sides of the splicing display module in the splicing direction being difficult to align, resulting in touch failure.
[0109] The first light bar 5122 can be an infrared light bar. When the spliced display module is in use, the infrared light-emitting elements on the infrared light bar on each display module emit infrared light to form a light network composed of infrared rays. When the user touches the display panel, the finger or other opaque objects will block the horizontal and vertical infrared rays passing through the touch point. The driving circuit board on the infrared light bar will parse the coordinate information of the contact point based on this, and send the information of the contact point to the control chip. The control chip generates display coordinate information based on the coordinate information of the contact point, and controls the display panel to display according to the generated display coordinate information.
[0110] In some examples, as shown in FIG11c , the first display module 101 further includes a timing control module (T-CON for short) and an OPS (Open Pluggable Specification, a computing module plug-in format) computer box. The second display module 102 further includes a timing control module. The timing control module is used to receive display information sent by the control chip and control the display panel for display. The OPS computer box is used to enhance the computing power of the first control chip. A shortened wiring design is used between the OPS and the first control chip as much as possible, such as a straight line connection, to reduce signal interference and radiation.
[0111] In some examples, the signal lines between the modules of the display module are routed separately, and the power lines between the display modules are routed separately, thereby avoiding mutual interference between the signal lines and the power lines.
[0112] FIG12 is a schematic diagram of the structure of the spliced display module provided by the present disclosure. In some examples, as shown in FIG12 , the first control chip 1011 includes an HDMI input port and an output port, a USB input port and an output port, and a VBO output port. The first control chip 1011 can be a SOC.
[0113] Typically, PCs, set-top boxes, and laptops transmit video signals to the display SoC. These signals are transmitted between external devices and use formats such as VGA, DVI, and HDMI. The SoC can convert video signals into formats supported by the TCON, such as VGA to LVDS and HDMI to VBO. The SoC can also control functions such as power on and off, backlight brightness, and audio playback.
[0114] Specifically, as shown in Figures 11c and 12, the first light bar 5122 of the first display module 101 on the first non-splicing side 101a or the first light bar 5122 of the first display module 101 on the third non-splicing side 101c can send the touch coordinate signal to the first control chip 1011 via a USB data cable. The first control chip 1011 can also receive an input signal from the HDMI input port, and the source of the input signal can be an external computer. The first control chip 1011 can send the display coordinate information to the second control chip 1021 via the HDMI output port. The first control chip 1011 can also send the display coordinate information to the timing control module via the VBO output port. The first control chip 1011 can also send the touch coordinate information to the OPS computer box via the USB output port, and receive the display coordinate information returned by the OPS computer box based on the touch coordinate signal via the HDMI input port. Among them, HDMI input and output can support multiple resolutions, for example, 2400*2160, 3840*2160 and other resolutions, VBO output can support multiple resolutions, for example, 2400*2160, 3840*2160 and other resolutions.
[0115] The spliced display module of the disclosed example supports touch signal input, realizing touch and display coordinate mapping; supports OPS computer box control and display; supports touch coordinate output and HDMI input. Through the spliced display module of the disclosed example, it is possible to realize the interaction of multiple display screens of multiple display modules, support multiple screens to display a complete screen in one, support each display screen to independently display different content, support three screens to independently display different applications, support the display screen of the second display module to synchronously display the same screen, support the display screens of multiple second display modules to exchange with each other, support multiple people to write on multiple display modules at the same time, support the saving of written content, and support wireless screen projection.

[0118] The driving circuit board of the infrared light bar of the first display module 101 located on the second non-splicing side 101c obtains a touch signal, parses the touch coordinate information based on the touch signal, and sends the touch coordinate information to the driving circuit board of the infrared light bar of the first display module 101 located on the first non-splicing side 101a. The coordinate information is then sent to the first control chip 1011 via the driving circuit board of the infrared light bar on the first non-splicing side 101a. The first control chip 1011 generates corresponding display coordinate information based on the coordinate information, and controls the display panel 20 for display based on the display coordinate information.
[0119] Scenario 2: The infrared light bar of the second display module 102 located on the first non-joined side 102a controls the display area 1 of the second display module 102, and the infrared light bar of the second display module 102 located on the third non-joined side 102c controls the display area 2 of the second display module 102, and the contact is located in the display area 1 of the second display module 102.
[0120] The driving circuit board of the infrared light bar of the second display module 102 located on the first non-splicing side 102a obtains the touch signal, parses the touch coordinate information based on the touch signal, and sends the touch coordinate information to the driving circuit board of the infrared light bar of the first display module 101 located on the first non-splicing side 101a. The coordinate information is sent to the first control chip via the driving circuit board of the infrared light bar on the first non-splicing side 101a. The first control chip generates corresponding display coordinate information based on the coordinate information and sends the display coordinate information to the second control chip 1021 of the second display module 102. After receiving the display coordinate information, the second control chip 1021 controls its corresponding display panel 20 for display.
