I have a theory that the defective screens lose the static charge that holds the ink particles because of the UV radiation. Window glass blocks most of the UV wavelengths.

I tried with slant sunlight in the evening through a glass pane, and there was a certain amount of fading. What's more interesting is the fact of the fading being almost inmediate at noon and outdoors, even in a (still) cold and sunny winter day.
By the way, thanks to everybody for your feedback!
