Hi, can anyone point me in the direction of a LCD (or similar device)
which has a high efficiency for the transmission of light when it is
``transparent'' but nearly nothing when it is ``opaque''.

From what I've been able to find out, 5% is about the norm when the
unit is transparent (due to polarisation etc.), whereas I'm looking
for something in the region of 30-50% (or better if possible).

Has anyone any suggestions ??
