The main reflective sheet has a main reflective surface for reflecting light, and the end face of the main reflective sheet near the first opening is the main reflective surface.

[0009] Optionally, the reflective part further includes two opposing first auxiliary reflective sheets, which are respectively fixedly covered on two opposing first inner wall surfaces in the installation space and are both located between the display panel and the back panel. The first auxiliary reflective sheet has a first auxiliary reflective surface for reflecting light, and the end face of the first auxiliary reflective sheet away from the first inner wall surface is the first auxiliary reflective surface.

[0010] Optionally, the electronic display board also includes a barrier element corresponding to a second inner wall surface in the mounting space, the second inner wall surface being adjacent to a first inner wall surface; the barrier element includes a barrier strip mounted on the end face of the support near the back panel, and capable of preventing the display panel from moving toward the back panel.

[0011] Optionally, the barrier also includes a support strip located on the side of the barrier strip near the back plate and connected to the barrier strip; the reflective part also includes a second auxiliary reflective sheet fixedly covering the surface of the support strip away from the second inner wall surface, the second auxiliary reflective sheet having a second auxiliary reflective surface for reflecting light, and the end face of the second auxiliary reflective sheet away from the second inner wall surface being the second auxiliary reflective surface.

[0012] Optionally, the support bar is inclined, and the support bar gradually tilts away from the second inner wall surface from the first opening to the second opening, so that a holding space is formed between the support bar and the second inner wall surface.

[0013] Optionally, the display screen also includes a display screen controller, the display panel being electrically connected to the display screen controller, which is located within the holding space.

[0014] Optionally, the electronic display board also includes a touch screen, which includes a touch panel and a touch screen controller. The touch panel is electrically connected to the touch screen controller, the touch panel is installed in the first opening, and the touch screen controller is located in the holding space.

[0015] Optionally, the electronic display board also includes a control unit, and a receiving space is provided in the front frame.

Then, the display panel is moved into the installation space through the second opening and mounted on the groove wall of the first mounting groove away from the back plate, so that the display panel remains in the installation space. Next, the optical enhancement component is moved into the installation space through the second opening, so that the optical enhancement component is located on the side of the display panel away from the first opening. Finally, the back plate is installed on the front frame so that the second opening is covered by the back plate. That is, the electronic display board in this application is assembled using an inverted assembly method. During the assembly process of the electronic display board in this application, since both the display panel and the optical enhancement component are located in the installation space through the second opening, there is no need to consider using components such as a middle frame to mount the display panel and press and fix the optical enhancement component. Therefore, the inverted assembly method for assembling the electronic display board in this application not only reduces assembly difficulty and increases assembly efficiency, but also results in a smaller assembled electronic display board.

[0033] As described in the background section, current electronic display boards include a back panel, a middle frame, a front frame, a display screen, a touch screen, and optical enhancement components (such as optical components like brightness enhancement films). The back panel, middle frame, and front frame are arranged sequentially along a predetermined direction. The components of the optical enhancement components are stacked sequentially on the end face of the back panel near the middle frame along the predetermined direction. The end face of the middle frame near the back panel is in contact with the component of the optical enhancement components furthest from the back panel. The middle frame is fixedly connected to the back panel to press the optical enhancement components onto the back panel. The display screen is located on the side of the optical enhancement components furthest from the back panel and mounted on the middle frame. The touch screen is located on the side of the display screen furthest from the optical enhancement components and mounted on the front frame. When assembling the electronic display board, the back panel is first placed on a mounting surface. Then, the components of the optical enhancement components are stacked sequentially on the end face of the back panel near the middle frame along the predetermined direction. Next, the middle frame is fixedly mounted on the end face of the back panel near the middle frame. Then, the display screen is fixedly mounted on the middle frame. Finally, the front frame with the touch screen is fixedly mounted on the end face of the middle frame furthest from the back panel. The existing electronic display boards have many components, making assembly cumbersome and the overall size quite large.

[0034] Reference Figures 1 to 3 as well as Figure 6To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides an electronic display board. The electronic display board includes a front frame 100, a display screen, an optical enhancement component 300, and a back panel 400. The front frame 100 has a mounting space 110, and the mounting space 110 has a first opening formed on the end face of a first end of the front frame 100. The display screen includes a display panel 210, which is disposed within the mounting space 110 and is capable of displaying an image that can be seen through the first opening. The optical enhancement component 300 is disposed within the mounting space 110 and located on the side of the display panel 210 away from the first opening, and is capable of improving the visual quality of the image. Effect: The back panel 400 is mounted on the front frame 100. The mounting space 110 has a second opening formed on the end face of the second end of the front frame 100. The display panel 210 and the optical improvement component 300 can both enter the mounting space 110 through the second opening. The back panel 400 at least partially covers the second opening. A support body 140 is mounted on the inner wall of the mounting space 110. A first mounting groove 141 is provided on the end face of the support body 140 near the back panel 400. The first mounting groove 141 extends to the side of the support body 140 away from the inner wall of the mounting space 110. The display panel 210 is partially mounted on the groove wall of the first mounting groove 141 away from the back panel 400.

[0035] In this embodiment, the display screen can use LED (Liquid Crystal Display) technology or OLCD (Organic Light-Emitting Diode) technology. The display panel 210 is used to display images and is parallel to the back panel 400. The front frame 100 is hollow to form an installation space 110. A first receiving groove 150 is provided on the end face of the front frame 100 near the back panel 400. A second receiving groove is provided on the bottom of the first receiving groove 150 and extends toward the interior of the front frame 100 (i.e., the installation space 110). The display panel 210 and the optical improvement component 300 can both enter the second receiving groove through the first receiving groove 150. The first receiving groove 150 forms a second opening, and the second receiving groove forms the installation space 110.

[0036] The support body 140 is a support boss, integrally formed around the circumference of the mounting space 110 and mounted on the inner wall of the mounting space 110. The display panel 210 can be fixedly attached to the support boss by adhesive or by using external devices to press and fix the display panel 210 onto the support boss. The support body 140 provides support for the display panel 210, facilitating its fixed installation within the mounting space 110. Furthermore, to ensure the integrity of the display panel 210, foam with elasticity and flexibility is adhered to the groove wall of the first mounting groove 141 away from the back plate 400. The display panel 210 is mounted on the surface of this foam near the back plate 400. Moreover, to facilitate assembly and disassembly of the display panel 210, grooves are provided at the corners of the support body 140 for easy insertion of tools or the fingers of operators. The optical enhancement component 300 can also be installed in the mounting space 110 by adhesive bonding to the inner wall of the mounting space 110 or by using a support platform fixedly mounted in the mounting space 110. The back plate 400 is mounted on the bottom of the first receiving groove 150. The end face of the back plate 400 near the first opening is in contact with the bottom of the first receiving groove 150, and the outer peripheral surface of the back plate 400 is in contact with the groove wall of the first receiving groove 150, so that the second opening is completely covered by the back plate 400. The back plate 400 is provided with connecting screws that penetrate the back plate 400 and screw into the front frame 100, so that the back plate 400 and the front frame 100 can be detachably connected. Of course, in other embodiments, the back plate 400 can also be directly mounted on the end face of the second end of the front frame 100 and completely cover the second opening; or the first receiving groove 150 and the second receiving groove have the same cross-section, and the outer peripheral surface of the back plate 400 is in contact with and fixedly connected to the groove wall of the first receiving groove 150, so that the back plate 400 just completely covers the second opening. The shape of the mounting space 110 is generally square. Of course, in other embodiments, the shape of the mounting space 110 can also be cylindrical, triangular prism, or other three-dimensional shapes.

[0037] When assembling the electronic display board, the front frame 100 is first placed on a placement plane or platform, with the first opening located below the second opening. Then, the display panel 210 is moved into the mounting space 110 through the second opening, and the display panel 210 is mounted on the groove wall of the first mounting groove 141 away from the back plate 400, so that the display panel 210 remains in the mounting space 110. Next, the optical improvement component 300 is moved into the mounting space 110 through the second opening, so that the optical improvement component 300 is located on the side of the display panel 210 away from the first opening. Finally, the back plate 400 is mounted on the front frame 100 so that the second opening is covered by the back plate 400. That is, the electronic display board in this application is assembled using an inverted assembly method. During the assembly of the electronic display board in this application, since both the display panel 210 and the optical improvement component 300 are located in the installation space 110 through the second opening, there is no need to consider using components such as a mid-frame to mount the display panel 210 and press and fix the optical improvement component 300. This makes the assembly of the electronic display board in this application by using the inverted assembly method not only easier and more efficient, but also results in a smaller size of the assembled electronic display board.

[0038] Reference Figure 1 and Figure 2 The electronic display board in this embodiment also includes a light-emitting element 500, which is mounted on the end face of the back plate 400 near the first opening. The light-emitting element 500 has a light-emitting end that emits light toward the display panel 210, and there is at least one light-emitting end.

[0039] In this embodiment, the light-emitting element 500 includes three light-emitting strips arranged along the length of the front frame 100. Each light-emitting strip is fixedly mounted on the end face of the back plate 400 near the first opening. The light-emitting strip has light-emitting beads that emit light toward the display panel 210. The light-emitting beads are formed as the light-emitting end of the light-emitting element 500. Of course, in other embodiments, the light-emitting strips may be one, two, or other numbers. The light-emitting element 500 provides a backlight source for the display panel 210 using LCD (Liquid Crystal Display) display technology, thereby ensuring that the display panel 210 can display images normally.

[0040] Reference Figures 1 to 4 In this embodiment, the optical enhancement component 300 includes a brightness enhancement sheet 310, which is mounted on the end face of the display panel 210 near the back plate 400 and at least partially covers the display panel 210.

[0041] In this embodiment, the brightness enhancement film 310 can be fixedly attached to the end face of the display panel 210 near the back plate 400 by adhesive bonding, or it can be fixedly mounted on the end face of the display panel 210 near the back plate 400 by using an external device to press and fix the brightness enhancement film 310. The brightness enhancement film 310 not only increases the brightness of the light illuminating the display panel 210, but also ensures that the light illuminating the display panel 210 is evenly distributed on the display panel 210.

[0042] Reference Figures 2 to 4 As an optional embodiment of this application, a second mounting groove 142 is provided on the end face of the support body 140 near the back plate 400. The second mounting groove 142 is located on the side of the first mounting groove 141 near the inner wall of the mounting space 110. The second mounting groove 142 extends into the first mounting groove 141. The groove wall of the second mounting groove 142 away from the back plate 400 is located between the groove wall of the first mounting groove 141 away from the back plate 400 and the back plate 400. The optical improvement component 300 also includes a diffuser plate 320. The diffuser plate 320 is partially mounted on the groove wall of the second mounting groove 142 away from the back plate 400 and partially covers the brightness enhancement film 310.

[0043] In this optional configuration, the diffuser plate 320 can be either glued to the groove wall of the second mounting groove 142 away from the back plate 400, or it can be fixed to the groove wall of the second mounting groove 142 away from the back plate 400 by using external devices to press and fix the diffuser plate 320. The diffuser plate 320 not only allows the light illuminating the display panel 210 to be more evenly distributed on the display panel 210, but also allows the light passing through the diffuser plate 320 to be evenly dispersed and scattered, thereby reducing the effects of reflection and glare.

[0044] Reference Figure 2 and Figure 4 As an optional embodiment of this application, the electronic display board also includes a limiting member 600, which is installed on the end face of the back plate 400 near the first opening. The limiting member 600 has a blocking end capable of blocking the display panel 210 from moving toward the back plate 400.

[0045] In this optional embodiment, the limiting member 600 is a limiting post. The first end of the limiting post is fixedly installed on the end face of the back plate 400 near the first opening, and the second end of the limiting post abuts against the end face of the diffuser plate 320 near the back plate 400. The second end of the limiting post forms a blocking end. Of course, in other embodiments, if the diffuser plate 320 is not present in the electronic display board, the blocking end of the limiting member 600 will abut against the brightness enhancement film 310. If neither the diffuser plate 320 nor the brightness enhancement film 310 is present in the electronic display board, the blocking end of the limiting member 600 will abut against the display panel 210. To enhance the blocking effect, multiple limiting members 600 are provided, and multiple limiting members 600 are fixedly installed at intervals on the end face of the back plate 400 near the first opening.

[0046] Reference Figure 1 and Figure 2 As an optional embodiment of this application, the optical improvement component 300 further includes a reflective part 330, which includes a main reflective sheet 331. The main reflective sheet 331 is disposed on the end face of the back plate 400 near the first opening. The main reflective sheet 331 has a main reflective surface for reflecting light, and the end face of the main reflective sheet 331 near the first opening is the main reflective surface. The main reflective sheet 331 is provided with at least one through hole. The number of through holes is the same as the number of light-emitting ends and corresponds one-to-one. The light-emitting ends are disposed in the through holes so that light can illuminate the display panel 210.

[0047] In this optional embodiment, the main reflector 331 is fixedly mounted on the end face of the back plate 400 near the first opening by adhesive. Of course, in other embodiments, the main reflector 331 can also be fixedly mounted on the end face of the back plate 400 near the first opening by connecting screws. The main reflector 331 is also provided with a through hole for the limiting member 600 to pass through. The main reflector 331 not only improves the utilization rate of the light emitted from the light-emitting end of the light-emitting element 500, but also improves the contrast of the display panel 210.

[0048] Reference Figure 1 and Figure 6 As an optional embodiment of this application, the reflective part 330 further includes two opposing first auxiliary reflective sheets 332. The two first auxiliary reflective sheets 332 are respectively fixedly covered on two opposing first inner wall surfaces on the mounting space 110 and are both located between the display panel 210 and the back plate 400. The first auxiliary reflective sheet 332 has a first auxiliary reflective surface for reflecting light, and the end face of the first auxiliary reflective sheet 332 away from the first inner wall surface is the first auxiliary reflective surface.

[0049] In this optional embodiment, the first auxiliary reflector 332 is fixedly installed on the corresponding first inner wall surface by adhesive. The first inner wall surface is a narrow inner wall surface on the installation space 110. Of course, in other embodiments, the first auxiliary reflector 332 can also be fixed and covered on the corresponding first inner wall surface by connecting screws. When both the diffuser plate 320 and the brightness enhancement plate 310 are present in the installation space 110, the first auxiliary reflector 332 is located between the diffuser plate 320 and the back plate 400. When only the brightness enhancement plate 310 is present in the installation space 110, the first auxiliary reflector 332 is located between the brightness enhancement plate 310 and the back plate 400. When only the display panel 210 is present in the installation space 110, the first auxiliary reflector 332 is located between the display panel 210 and the back plate 400. The two first auxiliary reflectors 332 further improve the utilization rate of the light emitted from the light-emitting end of the light-emitting element 500, and also further improve the contrast of the display panel 210. In addition, to facilitate the quick fixation of the first auxiliary reflector 332 to the first inner wall surface, a limiting protrusion is fixedly installed on the first inner wall surface. A limiting groove for the limiting protrusion to be inserted is provided on the surface of the first auxiliary reflector 332 away from the back plate 400. The first auxiliary reflector 332 and the front frame 100 can be quickly assembled through the cooperation of the limiting protrusion and the limiting groove.

[0050] Reference Figure 2 , Figure 3 and Figure 5 As an optional embodiment of this application, the electronic display board also includes a barrier 700, which corresponds to the second inner wall surface on the mounting space 110 and is adjacent to the first inner wall surface. The barrier 700 includes a barrier strip 710, which is installed on the end face of the support 140 near the back plate 400 and can prevent the display panel 210 from moving toward the back plate 400.

[0051] In this optional configuration, the second inner wall surface is the wide inner wall surface of the mounting space 110. The length direction of the barrier 700 is parallel to the length direction of the front frame 100. The surface of the barrier strip 710 away from the back plate 400 is in contact with the end face of the support 140 near the back plate 400. The barrier strip 710 can be detachably mounted on the support 140 using connecting screws or fixedly mounted on the support 140 by adhesive. When both the diffuser plate 320 and the brightness enhancement film 310 are present in the mounting space 110, the side of the diffuser plate 320 near the second inner wall surface is located between the side of the barrier strip 710 away from the second inner wall surface and the side of the barrier strip 710 near the second inner wall surface. The end face of the barrier strip 710 away from the back plate 400 can abut against the end face of the diffuser plate 320 near the back plate 400, thereby blocking the diffuser plate 320, the brightness enhancement film 310, and the display panel 210 from facing the back plate. When the brightness enhancement sheet 310 is moved to position 400, and only the brightness enhancement sheet 310 is present in the installation space 110, the side of the brightness enhancement sheet 310 near the second inner wall is located between the side of the barrier strip 710 away from the second inner wall and the side of the barrier strip 710 near the second inner wall. The end face of the barrier strip 710 away from the back plate 400 can abut against the end face of the brightness enhancement sheet 310 near the back plate 400 to prevent the brightness enhancement sheet 310 and the display panel 210 from facing the back plate 400. When the display panel 210 is present in the installation space 110, the side of the display panel 210 near the second inner wall is located between the side of the barrier strip 710 away from the second inner wall and the side of the barrier strip 710 near the second inner wall.

[0064] Reference Figure 9In this embodiment, the back panel 400 has at least one connection hole 410 on its surface away from the front frame 100 for inserting an external connecting device. In this embodiment, the electronic display board is usually installed on a wall, and a wall mount 1500 is usually installed on the wall. The four corners of the wall mount 1500 have connection through holes 1510 for screws or fixing pins to be inserted into the wall. A connecting pin to be inserted into the connection hole 410 is fixedly installed on the end face of the wall mount 1500 away from the wall. The connecting pin is formed as an external connecting device. The electronic display board and the wall can be connected by the connection pin and the connection hole 410. To enhance the stability of the electronic display board on the wall, there are four connection holes 410. Of course, in other embodiments, there may be two, three or other numbers of connection holes 410. In addition, to minimize the size of the electronic display board, connecting blocks are fixedly installed on the end face of the back plate 400 near the first opening. The number of connecting blocks is the same as the number of connecting holes 410, and they correspond one-to-one. The connecting holes 410 extend into the corresponding connecting blocks, but do not extend from the end face of the connecting block near the first opening to the outside of the connecting block. At the same time, to ensure that the connecting blocks do not affect the main reflector 331 and the light-emitting element 500, a convex frame extending towards the first opening is integrally formed on the end face of the back plate 400 near the first opening. The light-emitting element 500 is fixedly installed on the end face of the convex frame near the first opening, and the main reflector 331 is also fixedly installed on the end face of the convex frame near the first opening. Meanwhile, the end faces of each connecting block near the first opening are flush with the end faces of the convex frame near the first opening.

[0065] When assembling the electronic display board of this application, firstly, the touch panel 810 is fixedly installed in the first opening using double-sided tape. Alternatively, the light-emitting element 500 can be fixedly installed on the end face of the convex frame near the first opening. Then, the end of the first end of the limiting member 600 is fixedly installed on the end face of the back plate 400 near the first opening. Next, the main reflector 331 is fixedly installed on the end face of the convex frame near the first opening, with the light-emitting end of the light-emitting element 500 passing through the through hole on the main reflector 331, and the limiting end of the limiting member 600 passing through the through hole on the main reflector 331. After the above preparations are completed, the front frame 100 with the touch panel 810 is placed on the placement plane or platform, with the first opening located below the second opening. Then, the display panel 210 is moved into the installation space 110 through the second opening, and the display panel 210 is mounted on the groove wall of the first mounting groove 141 away from the back plate 400. Then, the brightness enhancement sheet 310 is moved into the installation space through the second opening. Within the mounting space 110, the brightness enhancement sheet 310 is mounted on the end face of the display panel 210 near the back plate 400. Next, the diffuser plate 320 is moved into the mounting space 110 through the second opening and mounted on the groove wall of the second mounting slot 142 away from the back plate 400. Then, two first auxiliary reflective sheets 332 are respectively fixed and covered on the two first inner walls of the mounting space 110. Finally, the blocking strip 710 on the blocking member 700 with the second auxiliary reflective sheet 333 is... The end face of the support 140 near the back plate 400 is fixedly attached to the support body 140. Then, the back plate 400 is fixedly embedded into the second opening, and the blocking end of the limiting member 600 abuts against the end face of the diffuser plate 320 near the back plate 400. Finally, the connecting hole 410 on the back plate 400 is aligned with the external connecting device fixedly installed on the wall, and the electronic display board is pushed toward the external connecting device so that the external connecting device is inserted into the connecting hole 410, thereby installing the electronic display board on the wall.

[0066] In summary, implementing the electronic display board provided in this embodiment has at least the following beneficial technical effects: When assembling the electronic display board, the front frame 100 is first placed on a placement plane or platform, with the first opening located below the second opening. Then, the display panel 210 is moved into the mounting space 110 through the second opening, and the display panel 210 is mounted on the groove wall of the first mounting groove 141 away from the back plate 400, so that the display panel 210 remains in the mounting space 110. Next, the optical improvement component 300 is moved into the mounting space 110 through the second opening, so that the optical improvement component 300 is located on the side of the display panel 210 away from the first opening. Finally, the back plate 400 is mounted on the front frame 100 so that the second opening is covered by the back plate 400. That is, the electronic display board in this application is assembled using an inverted assembly method. During the assembly of the electronic display board in this application, since both the display panel 210 and the optical improvement component 300 are located in the installation space 110 through the second opening, there is no need to consider using components such as a mid-frame to mount the display panel 210 and press and fix the optical improvement component 300. This makes the assembly of the electronic display board in this application by using the inverted assembly method not only easier and more efficient, but also results in a smaller size of the assembled electronic display board.
