Paper Abstract

Ferroelectric liquid crystals based on the smectic C* phase have been shown to have fast electro-optic switching by many workers. The development of a video rate VGA display by Thorn EMI Central Research Laboratories has been recently reported. In this paper we report on the development of a ferroelectric technology for printing applications. We describe a printhead technology based on a ferroelectric liquid crystal shutter array. The feasibility of the technology has been demonstrated by building a 300 dpi printhead which has been incorporated into an Oce electrophotographic printer.
