This may sound stupid, but from reading a product pamplete for some Japanese
LCD manafacturer, it said that after a while, TFT LCDs may "burn in" like CRTs,
though not as bad.  A screen saver is not a bad idea, even one that just blanks out
the LCD with nothing else.  I don't think this would happen with DSTN, however,
because it is displayed completely differently than TFT, which uses 3 transistors for
each pixel (red, green, blue).
