Abstract
A reflective mode liquid crystal cell having an integral self-actuating heater for maintaining a liquid crystal material in the cell above a temperature at which it solidifies. In this cell, the liquid crystal material is disposed between a transparent member, and a member having a nontransparent barium titanate portion. The barium titanate positive temperature coefficient of electrical resistance has a preselected Curie temperature above the temperature at which the liquid crystal material solidifies. A single power source can be used for electro-optic display, and heat generated by current flow through the barium titanate.
