ABSTRACT:
Large electronic signs usually employ either incandescent lights or magnetically manipulated elements. A simple alternative includes a plurality of juxtaposed modules on a transparent diffuser plate, each module being defined by a base plate, a top plate and a conductive, liquid crystal coating layer between the plates; transparent electrical contacts in the area of overhang between the top plate and the diffuser plate, and thin wires extending through the diffuser plate for carrying current to the contacts.
