The Notebook Review forums were hosted by TechTarget, who shut down them down on January 31, 2022. This static read-only archive was pulled by NBR forum users between January 20 and January 31, 2022, in an effort to make sure that the valuable technical information that had been posted on the forums is preserved. For current discussions, many NBR forum users moved over to NotebookTalk.net after the shutdown.
My thought was that its only the backlight just like CFL lightbulbs, and the danger there is not liquid mercury but metal mercury which is hardly dangerous at all.
there is a tiny CCFL backlight in the LCD, the mercury content in that is very small. As long as you don't disturb it (like actively touching the broken ccfl tube and lick it as such, then should be no inherent health danger. Just enclose the laptop LCD is some high grade garbage bags, and dispose them according to the local government regulations.
Metallic form of mercury are not easily passed into the body's circulation unless you have a wound (skin forms a barrier). Also, most toxic forms of mercury is organomercury (methyl mercury), which can impair the organ functions during high initial dose or prolonged exposure.
Get some fine zinc powders, and sprinkle it on the LCD, this should react with mercury and make it less likely to evaporate. But given how long you have kept the broken LCD around, you main precaution is to not touch the broken LCD pieces with your bare hand, and use a mask during the cleaning process if you are really paranoid about the health effects.
