## Burn-ins due to wrong LUTs
You may be wondering, for WW and BB lookup tables, **why don't we reaffirm the pixel status instead**? This would gretly improve the situation, as, even if a pixel is white and will stay white, we could apply the voltage needed to make sure it remains white, and clean any ghosting as well. If we do that, what happens is that pixel is that it sees a DC current applied always in the same sense (or more in one sense than in the other), the result is that it starts to semi-permanently polarize in one direction. The image of those pixels will start to be visible in the display even after days, because the microcapsules are no longer able to move from one direction to the other easily, as they oppose some resistence being *biased* towards one polarization.

I think that this effect in the past tricked a few people believing that with modified LUTs they osserved burn-ins of the pixels that were moved too fast, while actually they were observing a burn-in of *all* the other pixels instead, but the effect to the naked eye is that you see a problem only where there was some animation: actually these are the only pixels that are ok!
