While reading a pinned post started by SIMUL8R I realized something interesting about polarizers. There is no good reason they both have to be attached directly to the LCD. This is easiest if the damage is to the front polarizer, just remove the front polarizer entirely and put a much smaller piece of polarizing material just behind the projection lens.

I see from another thread that this is not a new idea, but seems to be in disfavor. There is a misconception that the polarizing filters need to both be touching the LCD. From a physics standpoint this is dead wrong, the only requirement is that the LCD be between the two polarizers and that the polarizers be 90 degrees rotated

Sounds like elken2004 reported that their might be slight loss of illumination due to reflection if the polar is not adhesed to the panel. This makes some sense that an additional optical surface would cause some reflected loss of light, but the same can be said of the tempered glass shield, the LCD, the fresnels, and the focusing lens. Now it is true that more light is lost through a polar than through glass, but that is true wherever the polar is. Perhaps others noticed a significant dimming when the polar was put into place? There is a massive dimming when the LCD is put into place, but we still keep putting them in there... usually my mantra is "when in doubt, experiment", but the only way to experiment with this is to have the same panel with and without the front polar, not likely. In the meantime I'm guessing the loss of light is marginal or similar to a standard LCD arrangement, and it beats the heck out of junking the panel.

Here's a tip. Just edit your first post and stop replying to yourself in every thread.

There have been a LOT of threads about Polar replacements. Keep searching and you will find them.
