The electrolytic liquid display is a new passive particularly designed for automotive applications. It looks like liquid crystal display but operates on a completely different way by electrolysis phenomenous. A small current at low voltage produces the transfer of silver from a back glass where silver is not visible to the front glass where the thin layer of silver obtained gives a black surface. This type of display fulfil almost all the requirements of automotive uses such as temperature operating range, viewing angle, shocks and vibrations.
Their manufacture operations are cheaper than those for liquid crystal and must finally give a lower manufacturing cost. At last one particularity is its memory effect which may be in some cases an advantage.
