Product Architecture
The WeatherBright™ LC3251 and LC4751 displays are based upon a large-area LCD, using interlaced
LED backlights. The Video Board provides an industry-standard video interface to the user. The
Junction Board accepts the power and serial inputs and manages the system with smart monitoring
and control. The system also incorporates a 12V power supply, fans, a diffuser, temperature sensor
boards, and an open-frame metal framework that mechanically holds the assembly together. A block
diagram of the primary system is shown in the following figure.
