I remove the polariz filter on the LCD (the one that face the lamp). Would that help the light passing through the LCD. Because I haven’t put it back and try it out, I just don’t have the time. And should I take the other side out too. THX

The polarizing filter is how the LCD works - it's an integral component, used to block the light that's been twisted 90 degrees out of phase by the liquid crystal.

If you take it off, your panel is useless.

But how is the polarizing filter? Is it a loose sheet, or is it stuck to the panel??

I have removed all loose sheets on the back of my panel, but I have not peeled anything of, and I have not removed anything from the front of the panel. Have I done something wrong? I have not yet tested the panel after I stripped it..


The Edge

Polarizers are dark films adhered to the panel. It would be very hard to remove them.

Maybe he is talking about the difuser

A question on this, if you wanted to, could you replace the filters with your own polarizing film? That would seem to be the easiest way to use all the screen real estate in a passive polarized 3D projector - buy some polarizing film, cut to size and stick 90 degrees offset from one side to the other and from one panel to the other. Both sides would have to be replaced, for a total of four sheets.

Or is there something about an LCD that would prevent this from working?
