Enemy of LCD screens, especially laptops.

Today I learned one new thing.
This discovery takes 3 laptops in which one acts as a constant variable, and a few years of time.


NEVER ever use ALCOHOL to clean your LCD SCREEN!!!!!!!!!!!!!!!!! DAMN IT!



Why?
The alcohol reacts with the LCD compound and causes white display to become yellowish.
You will notice this when you compare new laptops at the store and old ones.
Newer laptops often display a more bluish type of white.

Should you care?
No, unless it annoys you, which is often the case if you do photography and image editing.



Sad... sad... very sad only. ...and all this while I thought I am LCD screen's best friend... did weekly cleaning etc. Sheet.
