Abstract
An electro-optic display device having an activable surface. The surface including several separately activable zones, each zone having at least two sets of parallel discrete elements imbricated one in another and each set also separately activable. By simultaneously activating several different sets of elements, at least two separate imbricated patterns or data may be displayed simultaneously. The separate patterns may be observed independently through a reticulated transparent screen which may be movable to display one pattern, then the other.
Claims4
Passive electro-optic display device including an activable surface adapted to be observed through a reticulated transparent screen including a net having parallel lines permitting observation of different areas according to the incidence of observation of said screen, said device comprising:
- means for simultaneously displaying at least two different imbricated patterns on said activable surface, said means including said surface having several separately activable zones, each zone including at least two separate sets of discrete elements, the elements of each set alternating with those of the other set, each set of elements also being separately activable, and each element being parallel with one another.
