Abstract
The coupled interaction between the reorientation of a liquid crystal
and the migration of ionic impurities in the presence of an applied electric
field is investigated for two device types commonly used in displays, the
planar and the in-plane switching (IPS) cell. Simulated optical measurements
and transient currents are compared to experimental results in order to discover
means to alleviate the problems associated with ion migration. IPS cells have
a lower electrode surface area than planar cells, and are therefore more sensitive
to the movement of a given ion concentration. As a means to reduce this sensitivity,
the effect of altering the electrode width and gap is studied.
