Some believe that LED Displays emit too much heat. This is not true.
The heat conducted of an LED Display is distributed efficiently throughout the display (some displays store heat in a sink), making it at a normal temperature. LED Displays are designed to convert higher percentage of electricity in to light, that is why they generate lesser heat.
Moreover, indoor and outdoor LED Displays nowadays are customized depending on the environment it will be used. For example, outdoor displays normally require air conditioning system, fan, or customized cabinet appearance like Inewvation Wind-Thru LED Displays, while Inewvation indoor displays use die-cast aluminum parts in manufacturing.
