    I've seen severe CRT burn-in where text was in the same spot for prolonged times
    - login screens to mainframes
    - airport and train displays

    VFD (Vacuum Fluorescent Displays) are also prone to burn-in.
    I took some photos: ferretronix.com/tech/vfd

    I still use one of these (albeit different button placement):

    I estimate 35 years old. Is it less bright? Hard to say - I'm
    that that much older and still looks fine to me.

    Can't say the same for a Panasonic microwave fluorescent display
    which is maybe 10 years old.
