Vedclass · Answer

(C) Polycarbonate is commonly used in the production of $LCD$ ($Liquid$ $Crystal$ $Display$) screens,primarily because it is a durable,transparent plastic with excellent optical properties. Polycarbonate is used to make the outer layers of the screen or protective covers due to its high impact resistance and clarity.Here is a brief overview of the other options:- $(A)$ Polyacrylamide: Used mainly in water treatment,paper production,and as a thickening agent; not typically used in $LCD$s.- $(B)$ Buna-$N$: $A$ synthetic rubber (nitrile rubber) used for making seals,gaskets,and fuel hoses; not used in $LCD$s.- $(D)$ Perspex: Also known as acrylic,it is a transparent plastic,but it is more commonly used in optical devices,displays,and lenses rather than $LCD$ screens.
