Compared with indoor LED display, outdoor LED display should have higher resolution index ーー to meet all kinds of long-distance or high ambient light display effect. The resolution of the traditional LCD can only reach 1024 × 768, but according to the actual test data, the outdoor application needs the resolution of display equipment to reach at least 1920 × 1200, in order to display normally under the influence of sunlight, for LED advertising machine, “Resolution” will not become its application popularization too big problem. However, the outdoor environment is changeable, in order to make outdoor LED display adapt to the chaotic environment, in addition to“Resolution”, outdoor LED display in addition to high-resolution and what needs?

Outdoor LED display screen to waterproof and dustproof: want to be used outdoors, waterproof and dustproof is the first to face, display equipment shell protection level must achieve waterproof, general waterproof level IPX5, dust is an important factor that reduces the efficiency and accelerates the aging of commodities. Outdoor display equipment should have specially designed dustproof structure and dustproof filter commodities, and the dustproof grade should reach IP65.

The outdoor LED display screen should be kept at an intelligent constant temperature: the outdoor advertising machine will receive heat from the sun's radiation, air convection and internal electronic component heating when running, according to the regional temperature difference and equipment placement location of different LCD advertising machine to have to determine the temperature control program. Some are air-conditioning type heat dissipation, and some take forced air-cooling type heat dissipation. But no matter what kind of heat dissipation scheme, the commodity generally meets the temperature: -30 ° C ー55 ° C, Humidity: 10% ー90% operation requirements.

Outdoor LED display screen to anti-riot and anti-theft: outdoor display equipment is generally used in outdoor public places, public safety and the safety of equipment itself are outdoor display to consider the problem, general outdoor display equipment will use special toughened laminated glass, even if the glass is broken, it can only produce fine cracks similar to spider webs, the fragments of which firmly adhere to the middle layer, it can avoid personal injury or property loss caused by falling glass. In addition, facing the problem of anti-theft, should avoid the exposure of screws, and combined with anti-theft function of the lock and strong structural support to solve the problem of anti-theft. Outdoor LED display screen to lightning: in order to achieve all-weather outdoor performance, outdoor display equipment must have reliable lightning-proof control design, in thunderstorm for the equipment to provide security guarantee. Outdoor LED display screen to anti-reflection: the outdoor environment display interface clearly visible, anti-reflection is also an important aspect to consider, it is necessary to use a special coated glass, in order to improve the visual point of view and resolution of the screen, reduce the reflection of the screen. Anti-electromagnetic disturbance: the uncontrollability of outdoor environment makes the anti-electromagnetic disturbance function of outdoor display equipment become very important, but we can use the shielding method to the internal electrical components of the equipment, that is, to effectively prevent internal devices, cables on the signal disturbance, but also to prevent external electromagnetic interference on LED goods.
