- A new moiré pattern appearing in the off-state of a display
system with a reflecting surface under illumination of an external ambient
light source was analyzed. The origin of the new moiré pattern was
attributed to the moiré pattern which is formed on the reflecting surface by
external light and plays as a new light source with intensity profile.
Configuring an optically equivalent system with no reflecting surface layer
was proposed in order to overcome the limitation of new simulation
program, which was previously proved to be very efficient in computation
time but unable to handle a non-sequential system containing a reflecting
surface. It was verified that the new simulation algorithm combined with an
equivalent configuration could provide an accurate and computation timeefficient
analyses even for a system containing non-sequential stacked layer
such as a reflecting surface.
