      He Lilai Classic Outdoor Screen Case: Shanxi Taikoo High-speed Rail Station Square P16 Full Color Screen 1120㎡

    Compared with LED displays for indoor applications, outdoor LED advertising display have higher resolution indicators - to meet the effects of various long-distance or high ambient light conditions. The resolution of the traditional liquid crystal display can only reach 1024×768. But ccording to the actual test data, the resolution of the outdoor application to the display device needs to reach at least 1920×1200 in order to display normally under the influence of sunlight. For LED advertising display, "resolution" will not become a big problem for its application. However, the outdoor environment is changeable, in order to enable outdoor LED screen advertising machine to adapt to the messy environment, in addition to "resolution". These are still some  problems that the digital signage system must consider and solve from the indoor to the outdoor.: LED display waterproof, dustproof, anti-theft, lightning protection, riot, anti-reflection, anti-electromagnetic interference, etc. 

What does the outdoor LED screen need in addition to high resolution?

    Outdoor LED screen advertising display should proof water and dust, in order to fully use the outdoor display, waterproof and dustproof is the first difficult to conquer. And the device housing must be waterproof, the general waterproof level is IPX5 and can normal operation in heavy rain; Dust is an important factor in reducing commodity efficiency and accelerating the aging of products. Outdoor display must have a specially designed dust-proof structure and dust-proof filter products, and the dust-proof level should reach IP65.

Outdoor LED screen advertising display needs intelligent constant temperature: When the outdoor advertising display runs, there will be three primary heat sources: solar radiation, air convection, and internal electronic components. According to the regional temperature difference and the orientation of the device, the LED advertising displays must have certainty temperature control program. Some air-conditioning cooling, some take forced air-cooled heat dissipation. However, no matter what kind of cooling scheme, the commodity generally meets the temperature: -30 °C - 55 °C, humidity: 10% - 90% operating requirements.

Outdoor LED screen advertising display confidential anti-theft and antiexplosion : outdoor display equipment is generally used in outdoor public places, public safety and the safety of the equipment itself is the issue to be considered, the general outdoor display equipment will use special tempered laminated glass, even if damaged glass can only produce fine-grained cracks resembling spider webs. The chips adhere firmly to the middle layer to prevent personal injury or property damage caused by falling glass. In addition, facing the problem of anti-theft, the screws should be prevented from being exposed, combined with the anti-theft features of the locks and solid structural support, to solve the theft problem.

Outdoor LED screen advertising display should to against thunder: In order to complete all-weather outdoor playback performance, outdoor display equipment must also have a reliable lightning electronic control design, in the thunderstorm days to provide equipment security assurance.

Outdoor LED screen advertising display should anti-reflection: visible interface in the outdoor environment is clearly visible, anti-reflection is an important aspect to be considered, it is necessary to use special coated glass to improve the visual view and resolution of the screen, reducing screen reflections.

Anti-electromagnetic interference: The uncontrollability of the outdoor environment makes the anti-electromagnetic interference function of the outdoor display equipment very important. We can't reform the outdoor environment, but we can use a shielding method for the internal electrical parts of the equipment, which effectively prevents the internal devices and the signal by the cable and the signal and also can prevent the electromagnetic disturbance of the LED goods.
