However, the outdoor environment is changeable. In order to adapt the outdoor LED display to the chaotic environment, in addition to the "resolution", the LED display is waterproof, dustproof, anti-theft, lightning-proof, anti-riot, anti-reflection, anti-electromagnetic interference, etc. These are the problems that the digital signage system needs to think about and solve when moving from indoor to outdoor.

　　What else does outdoor LED display need besides high resolution?

1. Outdoor LED display should be waterproof and dustproof: if you want to use it all outdoors, waterproof and dustproof is the first thing you have to face. The protection level of the display device casing must be waterproof, and the general waterproof level is IPX5, which can be normal in heavy rain. Operation: Dust is an important factor that reduces product efficiency and accelerates product aging. Outdoor display equipment must have a specially designed dust-proof structure and dust-proof filter products, and the dust-proof level can reach IP65.

2. The outdoor LED display needs to be intelligent and constant temperature: When the outdoor advertising machine is running, there will be heat from three primary aspects: solar radiation, air convection, and internal electronic components heating. According to the regional temperature difference and the placement of the equipment, the LCD advertising machine must have Determine the temperature control plan. Some are air-conditioning type heat dissipation, and some adopt forced air-cooling type heat dissipation. But no matter what kind of heat dissipation scheme, the product generally meets the operating requirements of temperature: -30°C-55°C, humidity: 10%-90%.

3. Outdoor LED display should be anti-riot and anti-theft: Outdoor display equipment is generally used in outdoor public places. Public safety and the safety of the equipment itself are issues to be considered for outdoor display. General outdoor display equipment will use special tempered laminated glass. Even if the glass is broken, it can only produce fine spider web-like cracks, and the fragments are firmly adhered to the intermediate layer, which can avoid personal injury or property loss due to the falling of the glass. In addition, facing the problem of anti-theft, the screws should be avoided from being exposed, and the anti-theft function lock and solid structural support should be combined to solve the anti-theft problem.

　　4. Outdoor LED display should be lightning-proof: In order to complete the all-weather outdoor playback performance, outdoor display equipment must have a reliable lightning-proof and electric control design to provide safety guarantee for the equipment during thunderstorms.

5. Outdoor LED display should be anti-reflection: the display interface is clearly visible in the outdoor environment. Anti-reflection is also an important aspect to be considered. It is necessary to use glass with special coating treatment to improve the visual point of view and resolution of the screen. , To reduce screen reflections.

6. Anti-electromagnetic interference: The uncontrollability of the outdoor environment makes the anti-electromagnetic interference function of outdoor display equipment very important. We cannot modify the outdoor environment, but we can use shielding methods for the internal electrical parts of the equipment to effectively prevent The interference of internal devices and cables on the signal can also prevent external electromagnetic interference to LED products.
