Overview

Designed specifically for displaying video images from sources such as video recorders and camcorders, door security systems, CCD cameras or even hand-held games, Citizen's range of liquid crystal video modules all make use of "Chip-On-Glass" ( C.O.G. ) technology providing the following advantages:-

• High contrast image

• Excellent picture definition

• Compact, lightweight and robust design

Together with the combination of C.O.G. technology, the fast fluid liquid crystal and low resistivity I.T.O. (Indium-Tin Oxide) electrodes ensure that the image on the display is high quality and high contrast making it extremely clear and easy to see.
