Abstract
A dual layer liquid crystal display (LCD) is able to achieve a high
dynamic range by stacking two liquid crystal panels one on top of the other
over an enhanced backlight unit. However, the finite distance between the
two panels inevitably introduces a parallax error when the display is
observed off-axis, and the dynamic range limitations of the individual
panels introduce a reconstruction error near sharp edges in the input image.
In Part I, we have formulated the image splitting as a constrained
optimization problem in which a joint minimization of the parallax error and
the visibility of the reconstruction error is performed.In Part II, we describe one possible numerical method which solves the
optimization problem at a low computational cost. We also describe in more
detail the characteristics of the prototype display which has been built by
FIMI-Philips. We finally present some results and an evaluation of the
errors introduced by the proposed splitting algorithm.
