Example Embodiment

[0021] Combine Figure 1 to Figure 5 , The LED outdoor grid screen includes a box body 100, an LED lamp 200, a PCB board 300 and a protective bottom shell 400. The LED lamp 200 is mounted on the PCB board 300, and the PCB board 300 is hermetically connected to the protective bottom shell 400, and the protective bottom shell 400 protects the PCB board 300. The PCB board 300 and the protective bottom case 400 constitute the smallest display unit module. The PCB board 300 and the protective bottom shell 400 are fixedly installed in the box body 100, and the PCB board 300 is in contact with the box body 100.

[0022] In this embodiment, the box body 100 is a sheet metal box body, which is integrally formed by bending a whole plate. The surface flatness and consistency are greatly improved, and the mosaic and unevenness of the display area are greatly reduced. The box body 100 has a display panel, and the display panel is provided with a plurality of box body through holes to reduce...

Abstract

The invention relates to an outdoor LED grid screen. The outdoor LED (Light-Emitting Diode) grid screen comprises a box body, an LED lamp, a PCB (Printed Circuit Board), and a protective bottom case, wherein the LED lamp is arranged on the PCB; the PCB is hermetically connected with the protective bottom case, the protective bottom case protects the PCB, the PCB and the protective bottom case are fixedly arranged in the box body, and the PCB and the box body lean against each other. After being hermetically connected, the PCB and the protective bottom case are fixedly arranged in the box body, the protective bottom case can protect the PCB, so that the PCB is prevented from being directly exposed outside, corroded by rainwater, corroded, aged and damaged, the LED grid screen is further prevented from being damaged and can used outdoors, thereby greatly enhancing the applications of the LED grid screen.

Description

technical field [0001] The invention relates to an LED screen, in particular to an LED outdoor grid screen. Background technique [0002] In recent years, with the rapid development of LED technology, LED grid screens have become more and more popular and widely used in various fields. [0003] However, in the traditional LED grid screen, the PCB board is fixed on the box body, and the PCB board is exposed outside, without protection and waterproof. If it is installed outdoors, the PCB board is easily eroded by rain, prone to corrosion, aging or even damage, and easily causes damage to the LED grid screen. This makes the LED grid screen only suitable for indoor use, not suitable for outdoor use. This greatly limits the application of LED grid screens. Contents of the invention [0004] Based on this, it is necessary to provide an indestructible LED outdoor grid screen for the above-mentioned problem that the LED grid screen is easily damaged when installed outdoors.
