Abstract

Dot-matrix liquid-crystal displays may be constructed by fabricating heating elements at the intersections of mutually perpendicular X and Y address lines, so as to change the optical properties of a layer of heat-sensitive liquid-crystal material. However, the heater elements must have a very highly nonlinear electrical resistance in order to prevent nonaddressed elements from being energized through "sneak paths" formed by several other elements in series between the selected X and Y lines. As the number of display dots increases, the number of possible sneak paths also increases, requiring ever greater nonlinearity.
