As the electric field increases, the induced birefringence of a polymerstabilized bluephase liquid crystal gradually deviates from the conventional Kerr effect and finally saturates. A new convergence model, named extended Kerr effect, is proposed to explain this saturation phenomenon. This model will give a more accurate account on the electrooptic effect of the emerging blue phase LCDs.
