Briefly outline what lcd screen contain on the inside and why shouldn't it be opened by someone who is not qualified to work with one

Answers and explanations:

A) LCD stands for Liquid Crystal Display. The technology is widely used for televisions and other types of displays such as computer screens. Inside, LCDs have a liquid substance partly composed of mercury that changes between red, green, and blue once applied electrical voltage. Every LCD has a multipixel screen so those colors mixed can be portrayed.

B) Even if the mercury levels in an LCD are low, contact with it might cause allergic reactions, rashes or birth defects in pregnant women. That is the reason why somebody who is not technically trained to work with LCDs should not open them. In front of failures, the screen should be handled to the closest technical support.
