Focussing on polarization matrix optics in many forms, this book includes coverage of a wide range of
methods which have been applied to lCD modeling, ranging from the simple Jones matrix method to Co
elaborate and high accuracy algorithms suitable for off-axis optics. researchers and scientists are constantly d

striving for improved performance, faster response times, wide viewing angles, improved colour in liquid e
crystal display development, and with this comes the need to model lCD devices effectively. the authors l

have significant experience in dealing with the problems related to the practical application of liquid crystals, On
in particular their optical performance. g

The Society for Information Display (SID) is an international society which has the aim of a LCD Optical
encouraging the development of all aspects of the field of information display. Complementary
n
to the aims of the society, the Wiley–SID series is intended to explain the latest developments
in information display technology at a professional level. The broad scope of the series c
addresses all facets of information displays from technical aspects through systems
e
and prototypes to standards and ergonomics.
