Are flat panel computer monitors better to eyes than CRTs?

    If I understand right, flat panel computer monitors or laptop monitors
    use liquid crystal while regular monitors shoot electrons to the front
    of the monitor. I wonder if there's any study showing that the flat
    panel monitors cause less harm to eyes in any way. Thanks.

    Dear Yong,

    The accellerating voltage is about 25 Kv on most
    color monitors (last time I checked).

    This is enough to create "soft" X-Rays.
    I think the design of these CRTs is such as to mitigate
    this effect.

    The liquid crystal technology is different
    and would not have this effect -- to
    the best of my knowledge.

    Best,
