LED显示屏通常是由多个LED箱体或显示模组叠加组装而成，而LED箱体则是将控制模块（控制盒）、LED显示模组等通过各种连接方式固定在箱体框架上组成。由于常规显示屏通常由单个或多个钣金/型材箱体或压铸箱体拼接而成，其箱体结构十分复杂，钣金/型材箱体、压铸箱体都需要包含箱体安装结构和模组安装结构，空间上的冗余不可避免，笨重不美观，材料及加工成本有极少的降低空间。同时，常规LED模组上必须设有数据接口和电源接口，为避免低压大电流线路损耗过大，通常只能够将LED电源设置于显示模组附近，这样屏幕本体就需容纳模组、电源及其承载结构，导致LED显示屏厚度、重量、体积都较大，影响产品外观，且带来了高昂的成本。可见，常规LED显示屏厚度、重量、成本都难以大幅度减低，平整度难以提高，无法适应市场的需要、无法顺应产品轻薄化的时代潮流。The LED display is usually assembled by superimposing multiple LED boxes or display modules, and the LED box is to fix the control module (control box), LED display module, etc. on the box frame through various connection methods composition. Since conventional display screens are usually formed by splicing single or multiple sheet metal/profile boxes or die-casting boxes, the box structure is very complicated. Sheet metal/profile boxes and die-casting boxes need to include box installation structure and mold Group installation structure, redundancy in space is inevitable, heavy and unsightly, and there is very little room for reducing material and processing costs. At the same time, the conventional LED module must be equipped with a data interface and a power interface. In order to avoid excessive loss of low-voltage and high-current lines, usually the LED power supply can only be installed near the display module, so the screen body needs to accommodate the module, power supply and Its load-bearing structure results in large thickness, weight, and volume of the LED display, which affects the appearance of the product and brings high costs. It can be seen that the thickness, weight, and cost of conventional LED display screens are difficult to greatly reduce, and the flatness is difficult to improve, unable to meet the needs of the market, and unable to conform to the trend of the times of thin and light products.

The LED display device 100 includes a glass substrate 110 and a plurality of LED display modules 120. Each LED display module 120 is magnetically attracted. Installed and fixed on a glass substrate 110 provided with a number of magnetic adsorption structures 130. The magnetic adsorption structure 130 includes a first magnetic ring 131 and a steel ball 132. The steel ball 132 is attracted to the center of the first magnetic ring 131 so that the first magnetic ring 131 surrounds the corresponding The steel balls 132 are set.

在本实施例中，如图3所示，若干磁性吸附结构130按一定规则均匀分布在玻璃基板110的前表面上。如图1及图2所示，若干LED显示模组120呈矩阵分布在玻璃基板110的前表面上，LED显示模组120包括模组底壳121以及安设于模组底壳121上的模组PCB板122，模组PCB板122远离模组底壳121的一面为发光面（贴有LED灯珠），模组底壳121远离模组PCB板122的一侧设有若干铁磁性材料孔11，每一铁磁性材料孔11均与一磁性吸附结构130对应配合，以将LED显示模组120安装固定在玻璃基板110的前表面上。当LED显示模组120磁性吸附在玻璃基板110上时，钢珠132同时与玻璃基板110及模组底壳121接触且可以在相应的第一磁环131的中心（及铁磁性材料孔11的中心）转动。具体地，模组底壳121为矩形结构，模组底壳121远离模组PCB板122的一侧设有四个铁磁性材料孔11，每一铁磁性材料孔11邻近一模组底壳121的边角设置，使得每一LED显示模组120通过四个磁性吸附结构130安装固定在玻璃基板110的前表面上。模组底壳121远离模组PCB板122的一侧设有两横向相对设置的铁磁性材料块12，每一铁磁性材料块12均部分镂空形成两纵向相对设置的铁磁性材料孔11。通过四个铁磁性材料孔11与四个磁性吸附结构130一一对应配合以安装固定每一LED显示模组120的合理布局，可使得每一LED显示模组120更牢固、更稳定地吸附在玻璃基板110的前表面上。In this embodiment, as shown in FIG. 3, several magnetic adsorption structures 130 are uniformly distributed on the front surface of the glass substrate 110 according to a certain rule. As shown in Figures 1 and 2, a number of LED display modules 120 are distributed in a matrix on the front surface of the glass substrate 110. The LED display module 120 includes a module bottom shell 121 and a mold mounted on the module bottom shell 121. Set the PCB board 122, the side of the module PCB board 122 away from the module bottom shell 121 is a light-emitting surface (with LED lamp beads), and the side of the module bottom shell 121 away from the module PCB board 122 is provided with a number of ferromagnetic material holes 11. Each ferromagnetic material hole 11 is matched with a magnetic adsorption structure 130 to fix the LED display module 120 on the front surface of the glass substrate 110. When the LED display module 120 is magnetically adsorbed on the glass substrate 110, the steel ball 132 is in contact with the glass substrate 110 and the module bottom case 121 at the same time and can be positioned at the center of the corresponding first magnetic ring 131 (and the center of the ferromagnetic material hole 11). ) Rotate. Specifically, the module bottom shell 121 has a rectangular structure, and the side of the module bottom shell 121 away from the module PCB board 122 is provided with four ferromagnetic material holes 11, and each ferromagnetic material hole 11 is adjacent to a module bottom shell 121 The corners of each LED display module 120 are installed and fixed on the front surface of the glass substrate 110 through four magnetic adsorption structures 130. A side of the module bottom shell 121 away from the module PCB board 122 is provided with two laterally opposed ferromagnetic material blocks 12, and each ferromagnetic material block 12 is partially hollowed out to form two longitudinally opposed ferromagnetic material holes 11. The reasonable layout of installing and fixing each LED display module 120 through the four ferromagnetic material holes 11 and the four magnetic adsorption structures 130 in a one-to-one correspondence can make each LED display module 120 more firmly and stably adsorbed on On the front surface of the glass substrate 110.

如图2所示，模组底壳121远离模组PCB板122的一侧还设有四个第二磁环13，每一第二磁环13设于邻近模组底壳121的一侧边中心设置。左右相对设置的两第二磁环13的极性相反设置。上下相对设置的两第二磁环13的极性相反设置。这样一来，四个第二磁环13在LED显示模组120的背面呈不同极性磁环中心对称分布，因此，每个LED显示模组120与相邻的另一个LED显示模组120在上下左右皆为相吸，模组之间的拼缝、间隙可以显著的减少，进而可整体提高本LED显示装置100的显示效果。As shown in FIG. 2, the module bottom shell 121 is further provided with four second magnetic rings 13 on the side away from the module PCB board 122, and each second magnetic ring 13 is provided on a side adjacent to the module bottom shell 121 Center setting. The polarities of the two second magnetic rings 13 arranged opposite to each other are arranged oppositely. The polarities of the two second magnetic rings 13 arranged opposite to each other are arranged oppositely. In this way, the four second magnetic rings 13 are symmetrically distributed in the center of the magnetic rings with different polarities on the back of the LED display module 120. Therefore, each LED display module 120 is connected to another adjacent LED display module 120. The top, bottom, left, and right sides attract each other, and the seams and gaps between the modules can be significantly reduced, thereby improving the overall display effect of the LED display device 100.

如图3所示， LED显示装置110还包括固于玻璃基板的后表面上的控制盒150。如图2所示，模组底壳121远离模组PCB板122的一侧还设有FPC接口座1211，FPC接口座1211的内侧电性连接模组PCB板122。控制盒150于玻璃基板110的前表面引出若干FPC接口线缆151，每一LED显示模组120的FPC接口座1211通过一FPC接口线缆151与控制盒150进行供电与信号连接。这样一来，电源与信号采用一体式FPC接口线缆的设计，使得箱体厚度方向无需留出常规电源、信号接插件的空间，LED显示模组120装好后FPC接口线缆也可以隐藏在LED显示模组120与玻璃基板110之间。如此一来，模组底面与玻璃基板的距离仅为钢珠的直径，相对常规LED显示装置大大减少了空间冗余，使箱体轻薄美观，且简化了模组的安装过程，节约模组的组装时间。As shown in FIG. 3, the LED display device 110 further includes a control box 150 fixed on the rear surface of the glass substrate. As shown in FIG. 2, the side of the module bottom shell 121 away from the module PCB board 122 is further provided with an FPC interface seat 1211, and the inner side of the FPC interface seat 1211 is electrically connected to the module PCB board 122. The control box 150 leads out a number of FPC interface cables 151 on the front surface of the glass substrate 110, and the FPC interface socket 1211 of each LED display module 120 is connected to the control box 150 through an FPC interface cable 151 for power supply and signal. In this way, the power supply and signal adopt the integrated FPC interface cable design, so that there is no need to leave space for conventional power supply and signal connectors in the thickness direction of the box. After the LED display module 120 is installed, the FPC interface cable can also be hidden in Between the LED display module 120 and the glass substrate 110. In this way, the distance between the bottom surface of the module and the glass substrate is only the diameter of the steel ball. Compared with the conventional LED display device, the space redundancy is greatly reduced, the box body is thin and beautiful, and the installation process of the module is simplified, and the assembly of the module is saved. time.

Specifically, a number of iron blocks with holes can be fixed on the back of the module PCB board by welding or the like, and each iron block with holes forms a corresponding ferromagnetic material hole. Since the LED display module in this implementation adopts a bottom-less design, the FPC interface socket provided on the bottom of the module is directly set on the module PCB board, that is, the back of the module PCB board in this embodiment is also provided There is an FPC interface socket, and the FPC interface socket of each LED display module is connected to the control box for power supply and signal through an FPC interface cable.

以上结合附图对本发明的实施方式作了详细说明，但本发明不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本发明原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本发明的保护范围内。The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and modifications to these embodiments still fall within the protection scope of the present invention.

工业实用性Industrial applicability

本发明实施例提供的LED显示装置，其在玻璃基板的前表面上设置若干磁性吸附结构，以通过磁吸方式将LED显示模组安装固定在玻璃基板上，该磁性吸附结构包括第一磁环与钢珠，钢珠吸附于第一磁环的中心，使得第一磁环环绕相应的钢珠设置。这样一来，当LED显示模组磁性吸附在玻璃基板上时，钢珠同时与玻璃基板及模组底壳（或模组PCB板）接触且可以在相应的第一磁环的中心转动。由于玻璃基板的平整度很高，其平整度值可在RA0.005以下，同时，又由于LED显示模组安装固定后，钢珠与玻璃基板及模组底壳（或模组PCB板）直接接触，此时LED显示模组的平整度可以看作仅受模组底壳（或模组PCB板）的平整度的影响，而通过磁吸方式固定的模组底壳（或模组PCB板）的变形几乎可以忽略不计，且模组底壳（或模组PCB板）本身也有很高的平整度，因此相对传统LED箱体，采用本结构的LED显示装置可以有很好的平整度。可见，本技术方案，其可有效解决现有LED箱体平整度难以提高，无法适应市场的需要的技术问题。因此，具有工业实用性。In the LED display device provided by the embodiment of the present invention, a number of magnetic adsorption structures are arranged on the front surface of the glass substrate to magnetically mount and fix the LED display module on the glass substrate. The magnetic adsorption structure includes a first magnetic ring As with the steel ball, the steel ball is adsorbed to the center of the first magnetic ring, so that the first magnetic ring is arranged around the corresponding steel ball. In this way, when the LED display module is magnetically adsorbed on the glass substrate, the steel ball is in contact with the glass substrate and the module bottom shell (or the module PCB board) at the same time and can rotate at the center of the corresponding first magnetic ring. Since the flatness of the glass substrate is very high, its flatness value can be below RA0.005. At the same time, after the LED display module is installed and fixed, the steel ball is in direct contact with the glass substrate and the module bottom shell (or module PCB board) At this time, the flatness of the LED display module can be regarded as only affected by the flatness of the module bottom shell (or module PCB board), and the module bottom shell (or module PCB board) fixed by magnetic attraction The deformation of the module is almost negligible, and the module bottom shell (or module PCB board) itself also has a high flatness, so compared to the traditional LED box, the LED display device with this structure can have a good flatness. It can be seen that this technical solution can effectively solve the technical problem that the flatness of the existing LED cabinet is difficult to improve and cannot meet the needs of the market. Therefore, it has industrial applicability.
