What are the difference between INDOOR and OUTDOOR led screens?
From : http://www.szabsen.com/ Author : Time : 2008-11-4 16:08:29From a general point of view the difference between indoor and outdoor screens are the following:
1.Resolution: as the outdoor LED screen are usually watched from greater distances, they do not need the highest resolution (from great distance the human eye do not discriminate small details anyways). The cost due to the big dimensions is therefore compensated by the lower resolution needed to provide a good image quality.
2.IP level and cooling system: outdoor LED screens are treated with a particular ? Technique that grants an excellent resistance to water, salty air and corrosive intrusions typical of the outdoor installations. Moreover a particular forced-ventilation system guarantees that the temperature inside the module remains constant and does not pass the critical levels.
3.Against-sun and against-vandalism protection system: Outdoor LED maxi screens are provided of a special protection system that has the double function of protecting the screens from the sun (increasing the contrast levels and obtaining a better image) and from vandalism acts.
4.Brightness: the outdoor usage requires high brightness components in order to be visible from greater distances and most of all to contrast the direct sunlight.
