    HAHA... someone that knows something about the physics of polarizing materials.

    If you dont know what i mean check out this site, it expalians it a bit http://www.colorado.edu/physics/2000...rizationI.html ...and i thought that the stuff i learned in physics would never come up in real life....

    and im not sure how this can help your lcd problem...sorry.

    I meant twisting, not turning. So that your ears are up and down. You still want to be looking at the screen of course.

    Basically you want to try and align the polarity of your polarised sunglasses with that of the polarised filter in the lcd.

    I found this out on my European road trip last month. If I tilt my head 90 degrees to the side, so glassses are vertical, the screen is uber clear, even in sunlight, looking normally the screen is almost black.

    I was thinking, instead of this being a problem, couldn't we just recover the screen in a different polarising film and have it orientated at 90 degrees to what is already fitted?

    My polarised glasses seem to remove most of the glare and reflections which make the screen hard to see in sunlight, couldn't this be a cheap alternative to Transflective stuff... For those of us with specs

    Well you cant just flip the film since it is not square, so you will need new film. But essentially yes that is all you have to do.

    Thats why I mention using a different overlay film off a bigger monitor.

    I have a polarised antireflective film I got for a 15" monitor ages ago, might swap the lilli one for that, it'll be cool if it works

    Polarizing

    When I tried it with my older Lilliput, it seemed that the screen was polarized at 45 degrees.

    Which makes sense, in general, because it would then not be that affected by polarized lighting, etc. However, for car purposes, it would seem that being polarized to 0 degrees (or 180, depending on your point of view) would be much better...

    I think that's the case with mine, I had some polarized sheeting and on all of my lcds besides the lilliput, at 0 and 90, it would either be virtually crystal clear or black. On the lilliput, it wasn't at either 0 or 90 degrees, it would darken, but not even close to disappear at either orientation

    LOL, thanks. I used to get a pm or two a month asking for a full size pic, but discretion is the better part of valor.
