Solar Powered LEDBackLit™ Multi-Image Scrolling Display (Patent Pending) Technology:
The thickness and chemical composition of the diffuser used in the LEDBackLit™ modules distributes the light uniformly across the digital poster. An integrated micro-computer controls the poster film exposure time, system and light on/off. A pulse width modulation(PWM) module connects between a photovoltaic (PV) array and a storage battery, preventing the batteries from being overcharged.
