In addition to looking at resolution, six major issues need to be considered when purchasing outdoor LED displays

Compared with indoor LED display screens, outdoor LED display screens must have a higher resolution index-to meet the display effect of various long-distance or high ambient light conditions. The resolution of traditional liquid crystal displays can only reach 1024×768. According to actual test data, it is shown that outdoor applications must have a resolution of at least 1920×1200 for display equipment to display normally under the influence of sunlight. For LED advertisements The "resolution" will not become a big problem for its application popularization.

However, the outdoor environment is changeable. In order to adapt the outdoor LED display to the chaotic environment, in addition to the "resolution", what else does the outdoor LED display need in addition to the high resolution?  

  Outdoor LED display should be waterproof and dustproof: if you want to use it all outdoors, waterproof and dustproof is the first thing you must face. The protection level of the display device casing must be waterproof, and the general waterproof level is IPX5, which can operate normally in heavy rain; 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 grade can reach IP65. 

  Outdoor LED display needs to be intelligent and constant temperature: When outdoor advertising machine is running, there will be heat from three primary aspects: solar radiation, air convection, internal electronic component heating, etc., according to the regional temperature difference and equipment placement, the LCD advertising machine must have a certain temperature. Control program. Some are air-conditioning type heat dissipation, and some adopt forced air-cooling type heat dissipation. Regardless of the heat dissipation scheme, the product generally meets the operating requirements of temperature: -30°C-55°C, humidity: 10%-90%. 

  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. Generally, outdoor display equipment uses special tempered laminated glass, even if glass Damage 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.  

  Outdoor LED display should be lightning-proof: In order to complete 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.

 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 and reduce The screen is reflective.

  Anti-electromagnetic interference: The uncontrollable outdoor environment makes the anti-electromagnetic interference function of outdoor display equipment very important. We can't modify the outdoor environment, but we can use shielding methods for the internal electrical components of the equipment, that is, effectively prevent the internal components , The interference of the cable to the signal can also prevent the interference of the external electromagnetic to the LED product.
