does anyone know how toxic monochrome LCD screens from calculators actually are? growing up i was taught that these screens contain a liquid form of mercury, and that if you touch a cracked lcd screen you'll get mecury poisoning, is this actually true? i just found my old calculator but it got crushed by something heavy, basically the whole thing was just cracked open and so was the screen. anyways i just picked the caculator up without thinking and threw it in the trash, but i'm scared that i might accidentally have touched some mercury, so i guess my question is, can you get mercury poisoning by picking up a pulverized calculator with a cracked LCD screen? thanks for the help!
