Can magnets damage laptop screen?

[Bashar]

Since I originally ordered the DUEX from indiegogo last year I haven't attached the metal planets on any of my laptops because I'm afraid that the magnets damages the laptop screen after being attached too much to it because I remember when we were kids and placed some magnets on TV sets it turns blue or green (don't remember if it comes back later or not though)

I know technology has changed but thought of asking before attaching it, if you can share your experience that would be great

I have ThinkPads (W520 and X1 Yoga) and a MacBook Pro (old 2012/2013 model i think)

Thanks in advance
