The utility model discloses an outdoor tank body type LED display screen, which comprises a tank body, a power supply arranged in the tank body and a display module arranged on the tank body and is characterized in that the display module is sequentially provided with a mask fixed layer, a luminous cup layer, a PCB (printed circuit board), an aluminum plate and a sealing glue layer from outside to inside, wherein LEDs are arranged on the PCB in an array shape and are directly arranged on an LED chip of the PCB through solid crystals and bonding wires. In the LED display screen, the LED chip is directly packaged, thereby not only ensuring the consistent luminous property and the uniform color mixture so as to be appropriate for producing a high-density display screen, but also reducing the processing procedures and lowering the production cost.

本实用新型公开了一种户外箱体式LED显示屏，包括有箱体、装在箱体内的电源、装在箱体上的显示模组，其特征在于：该显示模组由外到内依次设有面罩固定层、发光杯层、PCB、铝板和封胶层，该PCB上呈阵列状设置有LED，该LED为经固晶、焊线直接设在PCB上的LED芯片。本实用新型将LED芯片直接封装，不仅能保证发光性能一致、混色均匀，适宜生产高密度显示屏，而且减少了加工步骤，降低了生产成本。

At present, the existing outdoor displays are generally used inline or surface mount LED full color LED, the production method is: Is the procurement luminous tube into PCB (or mount) plus waterproof sealant after welding Load Case is made, this production process nearly 20 years no major substantive improvements, the current is still in widespread use. Problems are: Inline lights display mixed color; surface mount waterproof and heat dissipation effect is poor, difficult to achieve both high-density, two limiting further enhance the quality of the display, but also due to line lights, surface mounted lights required by another factory or workshop production, higher production costs.

目前，现有的户外显示屏一般都采用直插式LED或表面贴装式全彩LED，其生产方 法是：是对采购发光管插入PCB (或贴装）焊接加防水胶密封后装入箱体而成，这种生产工 艺近20年没有大的实质改进，目前依然在广泛使用。存在问题是：直插灯显示屏混色差；表 面贴装式防水及散热效果差，二者很难实现高密度，二者限制了显示屏品质进一步提升，而 且因直插灯、表面贴装灯需要由另一生产厂或车间生产，生产成本较高。

The aim of this practical new technologies for existing deficiencies, to provide a new outdoor box-type LED display, the LED chip package directly, not only to ensure consistent luminescent properties, blending evenly, suitable for the production of high-density display screen, and reducing the processing steps, reducing production costs.

本实用新型的目的在于针对现有技术的不足，提供一种新的户外箱体式LED显示 屏，将LED芯片直接封装，不仅能保证发光性能一致、混色均勻，适宜生产高密度显示屏，而 且减少了加工步骤，降低了生产成本。

The utility model is the use of the following technical solution to achieve the above objective: An Outdoor LED Display Cabinet, including the box, mounted in the housing supply, installed in the box on the display module, wherein that: the display module from the outside to the inside in turn has a fixed mask layer, a luminescent layer cups, PCB, aluminum and sealed tube, the PCB is provided with a matrix form on the LED, the LED is a solid-crystal, wire located directly LED chips on the PCB.

本实用新型是采用如下技术方案来实现上述目的：一种户外箱体式LED显示屏， 包括有箱体、装在箱体内的电源、装在箱体上的显示模组，其特征在于：该显示模组由外到 内依次设有面罩固定层、发光杯层、PCB、铝板和封胶层，该PCB上呈矩阵状设置有LED，该 LED为经固晶、焊线直接设在PCB上的LED芯片。

This utility model using the techniques above scheme can achieve beneficial effects:

1 The utility model directly to the LED chip by the solid crystal, wire process settings on the PCB, not only saves DIP, SMD LED factory or by another independent workshop production costs, but also due to the production process unanimously, to ensure consistent performance LED light, greatly enhance the display quality.

The utility model LED Cup layer and the PCB, between the use of aluminum glue curing, but also in the fixed layer and the mask layer is provided between the light-emitting cup sealing gasket, while ensuring the waterproofing effect, changing the existing display screen module from the outer surface of cabinet installation or maintenance of the traditional process, achieved by the installation and maintenance inside the box, so that the latter becomes easy maintenance and viable.

本实用新型采用以上技术方案所能达到的有益效果是：

1.本实用新型直接将LED芯片经固晶、焊线工艺设置在PCB上，不仅节省了直插、 表贴发光管由另一工厂或独立车间的生产费用，而且因生产工艺一致，保证了 LED发光性 能一致，大大提升了显示屏的品质。

2.本实用新型的发光杯层与PCB、铝板之间采用胶水固化，而且在面罩固定层与 发光杯层之间设有密封胶圈，在保证防水效果同时，改变了现有显示屏模组由箱体外侧面 安装或维护的传统工艺，实现由箱体内部进行安装和维护，使后期维护变为方便和可行。
