Outdoor display LEDs are any LED based displays used outdoors. The displays are specially designed to withstand the harsh challenges found in the outdoors. High-quality LED chips are used on the screens, which guarantee uniform brightness and color over time and even in the sunlight and extreme heat. Antiglare coatings specially designed to minimize reflections from bright sunlight are also used in outdoor display LEDs. Aside from advertising, these displays are useful in the public domain for information dissemination, like showing traffic information on highway billboards, event timetables in outdoor facilities, etc. The displays are more often than not bolted to strong structures to enable them to endure to strong winds and other weather survivors forces. The displays require constant power to turn on, and so need to be connected to reliable power sources.
