Let me answer your question with why you should not open an lcd screen without experience and qualifications. Number one, the lcd screen runs on very high voltages that’s why they usually put a sticker on the back that says do not touch, the high voltage can cause ether fatal and non fatal injuries but are very painful ether way. Number 2 it is said that the lcd screen’s liquid crystal contains mercury vapors that can lead to death if not disposed properly. They are fragile, and there is a potential danger of mercury-vapour if the screen leaks some of it. So I recommend you shouldn’t open a lcd screen unless you know what your doing. If your trying to fix a lcd screen it’s too much time and money plus it’s dangerous. Just spend a couple more dollars and instead buy a new display. You can scan the screens bar code it the back to find a replacement. Hope this helps

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.
