  With ever increasing popularity in the field of LED display in all, more and more places to apply outdoor LED advertising screen display as propaganda.
  Relative to the indoor application of LED display, outdoor LED advertising screen should have higher resolution indicators, in order to satisfy all kinds of long distance or apparent effect of high ambient light conditions.Traditional liquid crystal appeared only 1024 x 768 resolution, and according to the actual test data, the resolution of the outdoor application to show equipment needs to at least 1920 x 1200, can under the influence of the sun appeared normal, for the LED advertising screen, "resolution" will not become too big difficult problem of its application popularization.
  However, outdoor environment changing, in order to make outdoor LED advertising screen adaptive clutter environment, in addition to the "resolution", LED display of waterproof, dustproof, guard against theft, lightning protection, riot, reflection, preventing electromagnetic disturb and so on are digital sign system from indoor to outdoor to think and solve problems.
  Outdoor LED advertising without high resolution also need?
  Outdoor LED advertising screen to waterproof and dustproof: to all outdoor use, waterproof and dustproof is the first face, show equipment casing protection grade must be waterproof, waterproof level is IPX5 commonly, can run normally in the heavy rain;Dust is falling commodity efficiency and accelerate product aging, the important factors that appeared outdoor equipment should be specially designed dust and dust filtering commodity structure, dust-proof grade reaches IP65.
  Outdoor LED advertising screen to intelligent thermostat: outdoor advertising screen at run time from solar radiation, air convection, the internal electronic components of three principal aspects, such as fever heat, according to the regional difference in temperature and equipment placed different LCD screen to have temperature control scheme is determined.Have a plenty of KongDiaoXing type radiator, some compulsory air-cooled heat dissipation.But no matter what the cooling scheme, goods generally meet the temperature: - 30 ℃ - 55 ℃, humidity: 10% - 90% operation requirements.
  Outdoor LED advertising screen to riot anti-theft: outdoor equipment commonly used in outdoor public places, is open to public safety and the safety of the device itself appeared to thinking on the problems of general appeared outdoor equipment can use special tempered laminated glass, even if the glass is broken, also can produce similar spider mesh finely crack, pieces of its strong adhesion on the middle tier, can avoid the glass drop caused personal injury or property loss.In addition, the problem of guard against theft, should avoid screw exposed, and combining the anti-theft lock functions and the structure of the solid support, solve the security problem.
  Outdoor LED advertising screen to lightning protection: to complete the all-weather outdoor play performance, outdoor equipment must have the reliable lightning protection electric control design, the thunderstorm day for equipment supply security guarantees.
  Outdoor LED advertising screen to prevent reflection: outdoor environment show visible interface, the reflection is also a thinking to important aspect, it is necessary to adopt the special coating process of glass, in order to improve the image visual point of view and resolution, reduce the reflective screen.
  Uncontrollability of preventing electromagnetic disturb: outdoor environment, preventing electromagnetic disturb function appeared to outdoor equipment become very important, we can't go to outdoor environment, but we can internal shielding measures should be adopted for electrical parts of equipment, which effectively prevent internal components, cables for signal, but also to prevent external electromagnetic disturb of LED products.
