Interesting that a mirror backing was used for the first primitive example. Looking over how the light originates from the rear, I wouldn't think that even using a mirror back there should cause image doubling, as what comes from the back is only white light. Bouncing white light escaping through the back should only intensify the source light. The image isn't created until the light goes through a polarized layer, LC layer, another polarizing layer and TFT layer (s?) to emerge in the front. I would think there would more of a problem with image doubling if light from the front entered, and then reflected. Increasing the source fluorescent lamp(s) output is obviously a must. But I wonder if increasing the voltage to the TFTs would rotate the LCs more and get the light angle more aligned with the front polarizing filter. I'd think Toshiba would already have given them enough power to make the light angle and polarizing layer align... but I didn't get that far in my investigation. It seems that the colors are not created from the white light being refracted at different angles as in a prism. From what I read, it seems that there are 3 LCs for each pixel, each with a colored filter in front of it. Oh gosh... I've got to hit the hay! Baaaaaahhh... my kitty libby will have company soon.
