LED显示屏及 LED显示装置技术领域 LED display and LED display device

本发明涉及 LED显示领域，尤其是指一种 LED屏及 LED显示装置。背景技术 The present invention relates to the field of LED display, and more particularly to an LED screen and an LED display device. Background technique

近年来， LED显示屏所组成的大面积 LED显示装置的应用得到迅猛发展， LED 显示已成为城市信息现代化建设的标志，随着信息数字化以及显示技术的发展，已经广泛应用到银行、机场、车站、证券交易市场、海关、体育场以及舞台等场所。 In recent years, the application of large-area LED display devices composed of LED displays has been rapidly developed. LED display has become a symbol of urban information modernization. With the development of information digitization and display technology, it has been widely applied to banks, airports and stations. , stock exchange markets, customs, stadiums and stages.

然而现有 LED显示发展正遭遇着诸如：大显示面积的需求、恶劣应用环境的需求和高产能的需求，这些无疑对 LED显示屏的进一步发展构成了瓶颈。细分之下上述需求难点主要如下： However, the development of existing LED displays is encountering such demands as: large display area demand, demand for harsh application environments, and high throughput requirements, which undoubtedly pose a bottleneck for the further development of LED displays. The above difficulties in the sub-division are mainly as follows:

1、伴随着 LED显示面积的扩大，采用何种快捷的装配结构是一大难题，对比目前行业同类 LED显示屏模组用于相连的结构而言，行业采用边锁结构，特别是对于超薄 LED显示屏模组而言为了连接还需要专门设置于显示单元同宽的边框，无疑浪费了大量材料，加高了单个 LED显示屏模组产品的成本与体积，此外普遍的连接定位精度低的问题也一直困扰着业内，因此现有的连接结构较为不利于租赁行业使用。 1. With the expansion of LED display area, what kind of quick assembly structure is a big problem. Compared with the current similar LED display module used in the industry, the industry adopts side lock structure, especially for ultra-thin In order to connect, the LED display module also needs to be specially arranged on the frame with the same width of the display unit, which undoubtedly wastes a lot of materials, increases the cost and volume of the single LED display module product, and generally has low connection positioning accuracy. The problem has also plagued the industry, so the existing connection structure is not conducive to the use of the rental industry.

而如何及时为大面积的 LED显示屏进行散热也尤为重要，现有各类 LED显示屏均需设置相应散热装置，纵观目前行业同类产品，多采用铁箱、或铝箱体结构作为 LED显示屏的后壳，其多考虑到采用上述箱体结构，由于需要兼顾防水问题，后壳面积大、体积大，且可在箱体内安放风扇，通过强排方式实现散热，但那么大金属质地的后壳存在体积大、重量重的问题，使得 LED显示屏单体很笨重，使用及安装困难。此外传统结构中在金属后壳内加入风扇，风扇功率大转速高，也存在噪音大的问题。 How to timely dissipate heat for large-area LED displays is also very important. All kinds of LED displays need to be equipped with corresponding heat-dissipating devices. Throughout the current industry similar products, iron boxes or aluminum cabinet structures are often used as LED displays. The rear shell of the screen is considered to adopt the above-mentioned box structure. Due to the need to balance the waterproof problem, the rear shell has a large area and a large volume, and a fan can be placed in the box body to achieve heat dissipation by a strong discharge method, but the metal texture is large. The back shell has the problems of large volume and heavy weight, which makes the LED display unit cumbersome and difficult to use and install. In addition, in the conventional structure, a fan is added to the metal back shell, and the fan has a large power and a high rotation speed, and there is also a problem of high noise.

2、恶劣的应用环境使得产品本身能防风，在此基础上还不能因为间隔设置灯条后影响观众观看的适当效果，而高产能则要求 LED从结构上对生产效率进行优化设计。而现有 LED显示屏的面罩上通孔的上下两侧设置水平方向、或左 _ 右两侧设置垂直方向的凸起于面罩的凸棱，该凸棱用于保护 LED灯珠。 LED显示模组一般为竖直或水平安装，观众观看显示屏时会形成一定的角度，而凸起于面罩的凸棱高于 LED灯珠，因而当观众观看 LED显示模组时会遮挡 LED灯珠发出的光线，影响观众对显示屏的观看效果。 2, the harsh application environment makes the product itself windproof. On this basis, it is not possible to influence the viewer's proper effect after setting the light bar at intervals. The high productivity requires the LED to optimize the design efficiency from the structure. On the upper and lower sides of the through hole of the mask of the existing LED display, the horizontal direction or the left side is set. _ The right side is provided with a protrusion protruding in the vertical direction to the rim of the mask, which is used to protect the LED lamp bead. The LED display module is generally installed vertically or horizontally. The viewer will form a certain angle when viewing the display screen, and the ridges protruding from the mask are higher than the LED lamp beads, so that the viewer will block the LED lights when viewing the LED display module. The light from the beads affects the viewer's viewing of the display.

3、现有显示屏结构中多是直接将显示模组的灯板直接固定在金属背板上，虽可使得灯板背后的电路直接与金属背板接触方便其热量的散发，但由于电路上有芯片元器件突出表面，就必须在金属背板上对应位置扣洞，从而方可将灯板固定在金属背板上，如此做来，一则扣洞的加工周期长，且工艺要求加工精度高，不利于 LED显示模组的大批量生产。发明内容 3. In the existing display structure, the light panel of the display module is directly fixed on the metal back plate, although the circuit behind the light board can be directly contacted with the metal back plate to facilitate the heat dissipation thereof, but due to the circuit If there is a chip component protruding surface, it is necessary to buckle the hole at the corresponding position on the metal back plate, so that the lamp board can be fixed on the metal back plate, so that the processing cycle of one button hole is long, and the processing precision is required. High, not conducive to mass production of LED display modules. Summary of the invention

Between the surface of the thermal pad 8 and the lamp plate 7 and between the back plate 6, a positioning hole/positioning post 8-3 for limiting is provided.

参见图 3、图 5 , 作为一实施例，本专利中的导热垫板 8包括相背的第一表面与第二表面，为了保证导热垫板 8与灯板 7、背板 6的连接，导热垫板 8于第一表面对应灯板 7设有定位柱，对应的灯板 7上设置有卡孔，而导热垫板 8的第二表面同样对应背板 6设有定位柱 8-3 , 背板 6上则对应设有定位孔。此外在导热垫板 8表面的器件让位槽 8-1厚度应当不小于灯板 7突出于元件（通常是芯片 7-1 ) 的最高高度，从而可免于原有工艺中背板 6加工扣洞的加工周期。 Referring to FIG. 3 and FIG. 5, as an embodiment, the thermal pad 8 of the present patent includes the first surface and the second surface opposite to each other. In order to ensure the connection between the thermal pad 8 and the lamp plate 7 and the back plate 6, heat conduction is performed.

The corresponding lamp board 7 is provided with a card hole, and the second surface of the heat conducting pad 8 is also provided with a positioning post 8-3 corresponding to the back plate 6. A positioning hole is correspondingly arranged on the plate 6. In addition, the thickness of the device on the surface of the thermal pad 8 is such that the thickness of the bit groove 8-1 is not less than the maximum height of the lamp plate 7 protruding from the component (usually the chip 7-1), thereby avoiding the processing of the back plate 6 in the original process.

进一步的，导热垫板 8的周边 /边缘设有软包边 8-4 , 最佳的，在导热垫板 8的四周设有软包边 8-2 , 且导热垫板 8整体可采用导热塑料制成，所述软包边 _ Further, the periphery/edge of the thermal pad 8 is provided with a soft rim 8-4. Preferably, a soft edging 8-2 is provided around the thermal pad 8, and the thermal pad 8 can be made of a thermally conductive plastic as a whole. Made, the soft edge _

8-2则采用软塑料 /软胶，由此导热垫板 8与软包边 8-2可通过双色注塑一体成型制成，生产效率高，大大缩短了生产工时。此外，在导热垫板 8 的边缘还可对应设置面罩安装让位槽 8-2 , 方便面罩 2的安装。 8-2 is made of soft plastic/soft rubber, so that the thermal pad 8 and the soft edging 8-2 can be made by two-color injection molding, which has high production efficiency and greatly shortens the production man-hour. In addition, at the edge of the thermal pad 8, a mask can be installed corresponding to the positioning groove 8-2 to facilitate the installation of the mask 2.

参见图 4、图 6 , 作为一实施例，本专利中的面罩 2的通孔 2-1是对应灯板 7上 LED灯珠呈点阵式排列的，且在通孔 2-1之间还设置有通孔 2-2 , 通孔 2-2 的形状可为半橢圓形、或圓台形、或圓柱形、或多棱柱形，最佳的，凸台 9-1 的上端面凸起于所述面罩 2且高于容置在所述通孔 2-1 内的 LED灯珠，以更好地保护 LED灯珠，避免其被碰撞损坏，而由于通孔 2-2是仅设置在通孔 2-1的四个端点位置外侧的，从而减少了对 LED灯珠发射的光线的遮挡，增大了对 LED 显示屏的可视角度，提高了观众观看的满意度。 Referring to FIG. 4 and FIG. 6, as an embodiment, the through hole 2-1 of the mask 2 in the patent is arranged in a dot matrix manner corresponding to the LED lamp beads on the lamp board 7, and is further between the through holes 2-1.
