What is the common size ratio of outdoor LED display?
Graphic screen: according to the contents of the show; video screen: generally 4: 3 or close to 4: 3; ideal ratio of 16: 9. According to the site size and beauty to do, if it is the wall to see your wall position and staircase size ratio, try to do big, even if the resolution to do low should try to choose a large area.
In accordance with the technical point of view, the curtain wall led display in the country are basically square, a little stereotyped, personal recommendations to do some creative to attract the shape. Such as cylindrical rows, the corner of the (such as Beijing Xu water high-speed rail station square square S8 outdoor surface paste), surprisingly designed to attract more people's eyes!
Outdoor LED display size design to consider the factors:
(1) the need to display the content;
(2) site space conditions;
(3) Display unit template size (indoor screen) or pixel size (outdoor screen).
Outdoor screen design and installation should consider factors:
(1) display installed in the outdoors, often sun and rain, wind and dust cover, the working environment is bad. Electronic equipment is damp or severe damp will cause a short circuit or even fire, causing failure or even fire, causing losses;
(2) the display may be caused by lightning strong magnetic field attack;
(3) the ambient temperature changes greatly. The display work itself to produce a certain amount of heat, if the ambient temperature is too high and poor heat, the integrated circuit may work is not normal, or even burned, so that the display system can not work;
(4) wide audience, wide distance requirements, wide field of vision requirements; large changes in ambient light, in particular, may be exposed to direct sunlight.
For the above special requirements, outdoor display must be done:
(1) screen body and the screen body and the building must be strict waterproof and leakproof; screen body to have a good drainage measures, once the occurrence of water can be discharged smoothly;
(2) Install lightning protection devices on displays and buildings. The display body and the shell to maintain a good grounding, grounding resistance is less than 3 ohms, so that lightning caused by the timely discharge of large current;
(3) installation of ventilation equipment cooling, so that the internal temperature of the screen between -10 ℃ ~ 40 ℃. The top of the screen body installed above the axial fan, discharge heat;
(4) use the working temperature of -40 ℃ ~ 80 ℃ between the industrial-grade integrated circuit chip to prevent the winter temperature is too low so that the display can not start. ;
(5) in order to ensure that the environment in the case of strong long-range visual, you must use ultra-high brightness light-emitting diodes;
(6) display media selection of new wide viewing angle tube, wide viewing angle, pure color, consistent coordination, life of more than 100,000 hours.
