Abstract

Briefly, an intelligent label is disclosed that has two viewable surfaces. Each surface is constructed such that a permanent and irreversible message may be set into each surface independently. That is, a first message may be set into the first viewing surface of the electro-optic material, and another message may be set into the second viewing surface, for example, at a later time. Various constructions are described including a construction using two pairs of stimulating electrodes, and a second construction using a single pair of stimulating electrodes.
