David,
Thank you for this wonderful information, although I have used LCD screens
for some time, and am a retired Physicist, I never realised the screens were
a source of polarised light. You are tempting me into some experiments.
In the past have been limited to around 6" square polarising sheets on the
light source, now plenty of source size available.
Regards,
Jim Thyer

Bob,
Thanks much ... however, I was mostly interested in whether it was a well
known fact in the photographic community that one could use an LCD display
as the background or source polarizer - saving on the expense of having to
buy a somewhat expensive plastic sheet polarizer or as an improvisation
when such an item is just not readily available, etc. Like if you live in
a place where there are no suppliers of polarizing materials. Like Oman??
BUT you do have an LCD display!!
Like Herschel! ;)

When I am wearing my "drivers' glasses", a pair of glasses I wear during
the day that has lenses made by, I think, the transitions people, my cell
phone display and the display on my mobile ham rig and the displays at
ATMs and gas pumps are difficult to read.
You may find info here http://www.lcd.kent.edu/ since Kent State
University is reported to be a leader in LCD research and applications.
