The brightness of LED displays used in outdoor applications can be reduced, if required. Appropriate location for large outdoor displays are based on the factors such as local authority planning requirement, line of sight, vehicular access, power and overhead obstructions. Outdoor LED displays enable end-users to carry out 24 hour advertising. Hence, these are being increasingly deployed in shopping malls, car dealerships, real estate offices and retail outlets. Furthermore, outdoor LED displays are also used for promotions of big events.
