Abstract
A box-like molded housing with an open front has a flexible printed circuit wrapped around it, the printed circuit having a terminal array attached to a housing flange adjacent the front opening. A frame having a translucent web or filter covers the open front and contains a liquid crystal cell. A slot in the frame contains an elastomeric connector for joining terminals on the cell with terminals on the printed circuit to provide control signals to the cell. The housing interior is a reflector cavity and contains lamps for illuminating the web and the cell through the web. The printed circuit carries surface mount components, supplies power to the lamps, and has a contact array for connection to spring contacts of an external connector.
