What should be paid attention to in addition to the resolution of outdoor LED display

　　Outdoor LED display should be waterproof and dust-proof: waterproof and dust-proof is the first thing to face if you want to use it outdoors. The protection level of the display equipment shell must be waterproof, and generally the waterproof level reaches IPX5, which can operate normally in heavy rain; Dust is an important factor to reduce the efficiency of goods and accelerate the aging of goods. Outdoor display equipment should have a specially designed dust-proof structure and dust-proof filtering goods, and the dust-proof grade should reach IP65.

　　The outdoor LED display screen should have intelligent constant temperature: when the outdoor advertising machine is running, it will have heat from the three primary aspects of solar radiation, air convection, and internal electronic components heating. The LCD advertising machine should have a temperature control scheme determined according to the regional temperature difference and the location of the equipment. Some are air conditioning type heat dissipation, and some are forced air cooling type heat dissipation. However, regardless of the heat dissipation scheme, the products generally meet the operating requirements of temperature: - 30 ℃ - 55 ℃, humidity: 10% - 90%.

　　Outdoor LED display screen shall be anti riot and anti-theft: outdoor display devices are generally used in outdoor public places. Public safety and the safety of the device itself are issues that should be considered for outdoor display. Generally, outdoor display devices will use special toughened laminated glass. Even if the glass is broken, only small cracks like spider webs can be generated, and the fragments are firmly adhered to the middle layer, It can avoid personal injury or property loss caused by glass falling. In addition, in the face of anti-theft problem, it is necessary to avoid exposing screws, and solve the anti-theft problem by combining anti-theft locks and solid structural support.

　　Lightning protection shall be provided for outdoor LED display screen: in order to achieve all-weather outdoor playing performance, outdoor display equipment shall also have reliable lightning protection and electric control design to ensure the safety of equipment in thunderstorm days.

　　Outdoor LED display screen shall be anti reflective: the display interface shall be clear and visible in outdoor environment, and anti reflective is also an important aspect to consider. It is necessary to use glass with special coating treatment to improve the visual point of view and resolution of the screen and reduce screen reflection.

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