Description

Technical Field

[0001] This utility model relates to the field of display technology, specifically to a flexible module LED display screen for outdoor display. Background Technology

[0002] Flexible module displays are popular in irregular installation scenarios due to their advantages such as deformability and lightweight design. Flexible modules use flexible substrate materials that can be bent and folded to adapt to the installation needs of irregular shapes. Flexible modules can realize screen designs of various shapes, providing more creative and unique display effects.

[0003] However, when used outdoors, although the power and signal connectors are equipped with protective covers, water may still seep in due to condensation or capillary action in heavy rain or high humidity environments. Frequent bending may loosen the protective covers, and the soft shell base has weak rigidity. After long-term stress or temperature deformation, the lamp board is prone to local warping, resulting in an uneven display surface, or even dim or dead lights. Utility Model Content

A prismatic column 22 is fixedly connected to the outer surface of the waterproof adhesive strip 24. The side of the prismatic column 22 is fixed to the outer surface of the flexible plate 21. The prismatic column 22 can connect the various parts, making the structure more compact. The diversion and drainage component includes a drainage component 25. The surface of component 25 is connected to the surface of flexible board 21. Connectors 26 are symmetrically installed on the outer surface of the hydrophobic component 25. The hydrophobic component 25 includes a hydrophobic plate 251. The surface of the hydrophobic plate 251 is connected to the surface of flexible board 21. The side of the hydrophobic plate 251 is fixed to the surface of the connector 26. A hydrophobic groove 252 is formed on the outer surface of the hydrophobic plate 251.

The side of the flow guide plate 36 is fixedly connected to the outer surface of the corner reinforcement 23.

[0029] The working principle of this outdoor flexible module LED display screen is described in detail below:

[0030] In use, this utility model forms a semi-enclosed structure by connecting the waterproof adhesive strip 24 to the flexible plate 21. The waterproof adhesive strip 24 fills the gap between the flexible plate 21 and the screen 1. The prismatic column 22 installed on the other side of the flexible plate 21 provides support and fixation, and can also prevent the lamp panel from warping. When the display screen is bent, the flexible plate 21, waterproof adhesive strip 24, hydrophobic plate 251 and prismatic column 22 will deform along with the deformation of the screen 1. The hydrophobic component 25 installed between the prismatic columns 22 causes rainwater to drip quickly along the hydrophobic groove 252 when encountering heavy rain. The guide plate 32 fixed on the outer surface of the rainproof box 31 can guide the rainwater from the guide groove to the drip cone 33, allowing the rainwater to drip from the top of the drip cone 33. The condenser tube 34 can actively condense water vapor in heavy rain or high humidity environments. The water droplets condensed from the water vapor will flow along the condenser tube 34 to the cold guide plate 36. A gap is provided between the two guide plates 36, and the water flows out from the gap to prevent water from entering the interface.
