ABSTRACT:
In a ferro-electric liquid crystal display, in which the pixels in one row first receive a reset or "blanking" signal, this reset signal is presented by providing the counter electrode, prior to selection, with a reset voltage while simultaneously selecting the row of pixels to be reset. When a single counter electrode is used, it switches to a reset voltage during each selection period. If the counter electrode is divided into sub-strips, these strips switch to a reset voltage once per picture period.
