I've seen some very high contrast LCD projectors with MLA. I believe it does increase contrast because the lens redirects light away from the transistor for each pixel. It is possible that the transitor scatters and/or changes the polarization of light travelling through it, reducing the amount of light passing through could increase the measureable contrast.


By high contrast I mean up in the 600:1 range (measured on/off, not specs). MLA contrast enhancement seems like the most plausible explanation.


Maybe someone with more knowledge of LCD technology can clarify this?

David,


"This is a means of increasing brightness....and thus contrast...I do not believe this does anything for the black level, which is why I laugh."


As pointed out in another thread you started, increasing brightness does not necessarily have anything to do with contrast. And as Kam rightfully points out, redirecting light so that instead of scattering and reducing contrast it usefully increases pixel illumination, both increased brightness and contrast can be achieved simultaneously.

Yes, but what I stated in another thread that was not perpetuated was that if you increase the lumens in a given projector, which has a limited capabillity to block light to produce absolute black, then you inherintly increase the black level.


THAT is why I laugh, because Vidikron, in esence, says that they increase brightness (with MLA), and thus black level, which I do not believe can go hand in hand with digital projectors of today.

However, as you correctly point out, this does NOT mean it can't do anything for contrast.
